Marine Careers

As a marine biologist, you will be expected to conduct different experiments as well as research on different animals and organisms. There can be several fields that you can readily be involved in. You can study organisms that have been existing for millions of years. You can also choose to study mammals and their behavior and habitats. You can choose to directly be a marine biologist, a teacher of it or a professor in a related field.

Becoming an Oceanographer

There are three main disciplines of oceanography namely physical oceanography, marine geology and geophysics and marine chemistry and geochemistry. All these three are related. Oceanographers using these disciplines usually work together to uncover the different mysteries of ocean science. Preference is provided to projects that mix the disciplines of oceanography and use vital principles from each one to create and learn an even, process or system.

Humans need to constantly look for more ways to provide water, shelter and food, since the global population continues to grow. The oceans still have a lot to offer to support human life for several centuries. Oceanographers work to learn more about the different locations and reactions of the ocean to find more ways to meet the growing demands of the world.

Engineering Underwater

If you are more interested in the engineering field, you can choose to become an ocean engineer. It provides vital links to other oceanographic disciplines like chemical and physical oceanography, marine biology and marine geology and geophysics. You get to help create and invent different oceanographic tools and devices that will change the way oceans and coasts are studied. Some of the well-known instruments include sediment traps, seismometers, acoustic measuring devices, underwater vehicles and underwater video equipment.

You can gather in a few minutes data that used to take years to complete. You can conveniently work even from remote places, such as laboratories and ships. The innovations and inventions of ocean engineers have allowed oceanographers to go farther offshore and into new depths. Discoveries have been made because of oceanographic engineers like ocean volcanoes, new species of plants and animals, physical processes and hydrothermal vents.

A Writing Job

Some marine biologists are very concerned about the current condition of the ocean. You may want to work as a reporter or writer to help people become more aware about the environmental effects of various inland processes. You can start a job in environmental reporting, science writing, public relations and communications. You may also want to teach and educate people directly in colleges, museums, aquariums and universities.

More Marine Jobs

If you finish Marine Biology, you can open a lot of career opportunities. You can become one of the related professionals: science writer, marine educator, ecotourism guide, maritime or environmental lawyer, aquavet, park ranger, filmmaker or photographer, marine historian, economist, marina manager, aquaculturist, spokesperson for grants or fundraiser, environmental planner, computer specialist, hatchery specialist or ship captain or mate. You have to gauge your own hobbies, knowledge, skills and specialties to determine the best potential career.

Vermicompost And Waste Management

Numbers will show you how much the world has gone to the dumps. An average American would have about .75 tons of trash every year, according to the U.S. Environmental Protection Agency. Most of the world’s waste came from industrialized countries. These countries have waste management laws, especially for hazardous wastes, but still experience problems with dumpsites and waste disposal.

Solving waste management problems do not have to take you anywhere else, you could start solving trash problems at home. Small contributions like this could go a long way. About 25 percent of our wastes are yard trimmings or food scraps. Although, a lot of people are learning to recycle and reuse plastic, metal, glass and other similar items, biodegradable stuff are nearly not recycled at all.

A great way to recycle food scrap is having a compost bin or by vermicomposting. Vermicomposting is another way of composting. Worms are used in the process to produce vermicompost, a rich soil which is a great way to fertilize a garden. There are different kinds of worms used in vermicomposting, like the red worms, white worms, and earthworms. These worms would produce vermicast which are worm castings or worm humus. Worms used in vermicomposting can be available from vermicompost enthusiasts or from a supplier.

Worms can be eat a lot of your food scraps and wastes, like vegetables, fruits, coffee grounds, tea, and even eggshells. However, avoid feeding them with bones, dairy products, spicy food, oily food and animal manure. Beddings for vermicompost bins can also be made out of household materials like newspaper and cardboard.

Different type of containers could work, as long as they would protect the worms from too warm or cold weather conditions. Worms are comfortable in temperatures ranging from 55 to 77 degrees Fahrenheit. Most commonly used bins are those made of wood or plastic. A 12-inch deep compost bin can accommodate about a pound or 1,000 worms. Odour does not have to be a problem. A vermicompost bin which is done properly will not give out any smell.

There are many benefits associated with vermicompost. The vermicast is 10 to 20 higher in nutrients compared with other organic material used to enrich soil. It can also improve the soil’s water holding capacity. Enriching the soil could enhance plant growth and the crops yielded. If you have a vegetable patch, this would be a great way to reduce food waste and increase productivity from your patch using chemical-free fertilizers.

In the United States, there are states like Illinois, who are banning landscape waste in landfills. Vermicomposting is a great way to address disposal of these kinds of waste. Aside from that, there are some who would use vermicomposting as another source of income. They would sell vermicast, it is often times called “Black Gold” because of its high nutrient content. Others would supply worms to fishermen or become a local supplier.

Using vermicomposting as a waste management method for food scraps and other biodegradable materials at home is surely a win-win solution. You get to reduce waste and benefit from it, whether it is short term or in the long run.

Solar Power for Homes: Things to Consider

Do you think that using solar power for home is a great idea? Well, only you can answer that question. Before you embark on any project, you must have enough knowledge about it. Make sure that you do your homework first and learn everything you can about solar power. The world is suffering greatly from global warming and one of the primary causes is the use of fossil fuels to create electricity. Electricity is a necessity and because of this fact, people can’t do away with it. There is a need to look for alternative energy sources and a very good one is the use of solar power.

Before you make a decision and use solar power for your home, here are the important considerations that you should look into:

1. Where do you live? What is the weather in your area? Is it always sunny in your area or is it always raining? Are there tall trees near your house? You must answer these questions first before you start with any DIY project to create solar power for your home. If the weather is frequently sunny, then it might be a good idea to use solar power. For those with lots of trees in their yard, you need to get rid of them but this is not a very easy thing to do since trees are also very important. Local authorities might not permit you to do cut down huge tall trees. Study the weather in your area as well as your location. To use solar power, you will need the rays of the sun. Rain, clouds, and trees can block the sun’s rays and so you might end up wasting money.
2. Where do you plan to install the solar panels? You must determine the place where there is lots of sunlight all throughout the day. You can’t install the solar panels in an area where there is very little sunlight. Study your home’s surroundings. Find the perfect place where the panels can get a lot of sunlight so that you can benefit from it greatly.
3. Do you have enough knowledge on how to connect solar power into the electricity grid of your home? You can also conduct a research about it. The solar power DIY projects usually provide a complete guide on how to install the solar power to your homes. Just follow the instructions carefully to avoid committing mistakes. If you’re not that sure, you can always get an electrician to help you with the task.

Solar power can reduce your monthly electric bills by more or less 80% depending on your solar power project. In no time at all, your home can become self sufficient and you will no longer depend largely on the conventional energy sources.

Aside from that, the carbon emissions are also reduced thereby saving the environment from further damage. With a solar powered home, you can enjoy an endless electric supply that is clean, green, and fresh.

Get a solar power DIY kit now and get the needed materials. You can also ask other family members to help you out. That is, if you think that solar power is best for your home. Go through the three considerations mentioned above so that you can make an informed decision. This is the time to save money and help the environment, act now.

Marine Biology Jobs You Can Do

Marine biology branches out into several disciplines and professions. Once you graduate from university, you can choose a variety of jobs where you can truly become effective. You should also gauge your level of interest in each field to determine which one will be most suited for your skills and knowledge. Learning more about the job description of each one will help you decide better. Here are some tips on some of the most common functions.

Be a Geophysicist

If you want to be a geophysicist or research oceanographer, you have to earn your doctorate degree first. You may be assigned to a technical job if you finished bachelor’s or master’s degrees in engineering and science. Expect to earn about $80,000 to $130,000 every year as a geophysicist. The average work lasts about 20 to 50 hours per week. You may also continue working on weekends.

Your work mainly involves studying seafloor images and maps via different software programs that analyze the processes that make features under the water like submarine volcanoes. Some of the big discoveries that this type of profession has made include documenting huge submarine debris flows and submarine landslides. Other discoveries are also apparent such as finding amazing sites in the Pacific and finding vents that emit caustic fluids and liquid carbon dioxide.

Be a Fish Ecologist

The fish ecologist or conservation biologist can go on several expeditions every year in different parts of the globe. You will need to earn your doctorate degree to be a professor. There are many other field positions if you finish your bachelor’s or master’s degrees such as working up lab samples, diving, running advanced equipment and conducting sampling. The average ecologist earns around $80,000 every year. Work can last anywhere between 40 to 60 hours per week.

Research by fish ecologists focuses more on the functions of habitat in changing the availability and distribution of fishes. The work can take place in a huge range of locations like on tropical coral reefs, outer continental shelf environments and the deep sea. You will use a variety of materials like submersibles, cameras, snorkel and scuba to gather data. Most professionals want others to understand the needed balance and the ethical obligations to save plant and animal communities.

The Marine Archaeologist

If you become a marine archaeologist, you get to coordinate heritage activities of the maritime program. You should focus more on the starting phases of marine archaeology like finding and studying shipwrecks. Hydrographers make use of remote sensing tools to go through the ocean floor and make nautical charts for secure investigation. The tools can also be used to look for prehistoric landscapes.

Helping Other Researchers

Researchers can manage sites better if the marine archaeologist gives a sensible inventory and manage remote sensing data. You should work well with other existing programs to create shipwreck rules to meet the requirements of communities. Extra protection and preservation is needed for the new shipwrecks found. Researchers can find lost ships and other landscapes more easily with the given data.

Tips For Household Waste Management

The numbers are increasing. The United Nations Development Programme estimates that there are five million people who die each year because of diseases related to inappropriate waste disposal. It is the developed countries who are generating more wastes. About .75 tons of trash is being produced annually by an individual in the United States, that is according to the United States Environmental Protection Agency or US EPA. It can be reduced through waste management.

Home waste management is not just about less trash, it is about protecting and saving the environment. You could start by monitoring what you actually throw and how much waste is hauled from your home. Monitoring what you dispose would help you deal with them using other methods. Waste management could be summed in three important words: reduce, reuse, recycle.

- Reducing wastes. Buying food in packs will add to your waste, try buying food loose like vegetables and fruits. You could also get your home appliances regularly maintained or repaired. This would give your appliances longer life and avoid throwing away equipments.

- Reusing items. Appliances or home equipment that are not being used can be donated to charity. You could also use a cotton bag for shopping, this would reduce paper or plastic bags that you will be taking home. There are different methods on how you can reuse or repurpose old items in the house. There are different websites that can give you different ideas. Also buy reusable items rather than disposable items. You could get water bottles or a coffee mug instead of frequently buying plastic water bottles or disposable coffee cups.

- Recycling. You could start having a composting bed at home. This would be great for the environment and for your garden, too. Vermiculture or worm farming is also another way to recycle your waste and even earn extra income. Look for recycling centers near your home to bring items that you would like be recycled.

Another source of household wastes is food waste. How do you reduce your food wastes? Then start by buying food that you would really consume and need. There are studies showing that about 74% of people will be making purchase decisions after entering the grocery store, which is why you need a shopping list.

But before you start shopping, check your household supplies first and identify which food should be consumed immediately. Be a smart shopper, think about what will happen to the food, its containers and packages before you go ahead and buy. Food could be stored in the refrigerator for longer life and fruit and vegetable peelings could go to your compost bin.

Another waste management concern is about hazardous materials found in our home. The United States government categorized about 500 hazardous wastes and how it should be disposed. These hazardous materials are very much present in our home like house cleaners, paint and pesticides. And hazardous wastes are not disposed just like any other trash. We could start using organic and chemical free cleaners. For paints, make sure that we are buying enough and not too much. For example, in Minnesota hazardous waste sites, in 1998, about 4 million pounds of excess paint was collected.

You are not only saving the environment, you are also making your home safer for your children.

Solar Power for Homes – Not Just For Rich People

Solar power is free. Well, that is, once you’ve finished installing the solar power system. Today, the homes that use solar power are limited and most of them come from the rich sectors of the society. The cost of installing solar power systems can range from $35,000 – $250,000. However, there are cost effective systems but you need to build them on your own. These DIY solar power kits can be obtained from $200 to $350.

Because of the technological advancements, a lot of homeowners are now able to use solar power at a very affordable cost. In some places, the government monitors the solar power consumption of some homes. Programs were also launched to encourage other homeowners to opt for solar power. For example, when the solar power consumption has reached a certain point, rebates will be given.

The expensive solar power systems can store the energy of the sun effectively in the batteries but the less costly versions are not that efficient. Still, if you try to scour the net, you can find homes that are successfully using DIY solar power systems. In Los Angeles California, a lot of homes now enjoy solar power to the fullest. It is always sunny in this area and it rarely rains. Before, solar panels were really ugly but because of today’s modern technology, the panels are more stylish and can blend well with the existing design of the house. Many homes in California now opt for solar power because of the constant blackouts. According to some experts, California is hoping to achieve a 10% overall consumption of solar power in the area by 2020.

Some celebrities also have solar powered homes in LA like Edward Norton, Julia Roberts, Larry Hagman, and Jackson Browne. Well, these celebrities can definitely afford to pay for the expensive installation of solar power systems. For starters, why don’t you try to install DIY kits? These are more affordable and if you like to do things on your own, this is an excellent project. However, when it comes to electrical matters, you will still need the services of an experienced electrician. The solar power will be connected to your existing electrical supply and so you might get electrocuted if you don’t have enough knowledge about it.

Going green these days is vital to save the environment. Global warming has taken its toll and people from all over the world can now feel the consequences. Using solar power is a very effective way to help save the environment so that you can no longer depend entirely on conventional electricity. Perhaps you’re already aware that electricity is generated by burning fossil fuels. The emissions from the burning of the fuels contribute to global warming. When you use solar power, you can decrease electrical consumption and in turn you can save a lot of money. Say goodbye to expensive electricity bills and save money.

Solar power for homes is for everyone and not just for the rich and famous. If you can’t afford the ready-made varieties, you can create your own by simply following a guided instruction provided by a reputable and established manufacturer of solar power systems. Choose the appropriate system. The size of the system should also be considered so that your electrical needs can be met. Install a solar power system in your home and witness its benefits.

Marine Biology: The Related Professions

If you study marine biology in university, you have to understand that there are several other professions that you can be eligible for. You can pursue further studies to become a professor and be assigned to the particular job that you are really interested in. You have to review the different features of the job before applying. This way, you minimize the time exploring and focus more on the aspects that can both fuel your passion and earning capacity.

The Research Coordinator

The managerial positions can land you a salary of about $75,000 to $100,000 each year, higher positions in institutional management can even reach up to $150,000 each year. As a research coordinator, you will need to create a sound expedition plan. You will also go on ships and submersibles. The work includes gathering of data and samples. The job can mean collecting invertebrates then getting extracts back at the laboratory. The extract will be checked and observed as well. Different chemicals found in the extract will be tested on different human diseases to know if there are any changes that can potentially treat.

The job requires a doctorate degree because of the high level of administrative and managerial work. You do not need to have the doctorate degree if you want to do lab work. You can also land a teaching job instead. Some courses will help you prepare better for the profession such as chemistry, molecular biology and biochemistry.

Being an Oceanographer

An oceanographer earns anywhere between $100,000 and $150,000 each year. Being a full professor can help you land teaching jobs and get a bigger salary. You will typically work about 60 hours each week. The job description entails creating new graduate programs in oceanography. You have to work with groups of graduate students and continue research in different oceans and seas to boost the telepresence program. You will be tasked to watch, study and gather data from creatures, habitats, sea vents and ecosystems.

Studying Mammals

Marine biologists will have to study different organisms, depending on their location and personal preference. If you become a marine mammal biologist, you have to earn a bachelor’s degree at the very least. However, most people in the position have a master’s or doctorate degree. Salary ranges anywhere between $40,000 and $80,000. The hours per week will depend on the project and deadlines. On the average, you have to work about 8 to 10 hours per day. Some of the work entails studying the ecology of marine mammals. You have to observe the behavior and interactions of seals, whales, sea otters and dolphins.

Study the Habitat

You have to study their environment as well at different phases of their lives. You will spend several months per year writing proposals and papers. You also have to learn how to apply for grants to fund your many researches. You will spend some time on a boat or submersible too, catching, tagging, viewing and counting marine mammals. You may discover some of the rarest species and inform others how to better protect them.

Saving Energy without Breaking a Bank

Energy is not just the monthly bill you have to pay each month; it is the foundation of everything you do and the life to everything you have. But with the increasing cost of energy, it cannot be denied that we need to take important measures to limit our energy consumption. Saving energy becomes a must and a habit that everyone should seriously adapt.

Heating and Cooling.

Almost half of your electric bill goes for your heating and cooling systems so if you really want to maximize your savings here are the following things you can do:

Clean your air filters at least once a month.

Clean baseboard heaters, radiators, and warm-air registers as often as necessary; make sure that they are working properly; and that they are not blocked by drapes, carpeting, and furniture.

Set the thermostat as high as is comfortable when it is hot or as low as is comfortable when it is cold.

Turn off exhaust fans (kitchen, bath, others) 20 minutes after cooking or bathing. Keeping them on for a long time affects the temperature of the room.

Lighting and Appliances

As much as possible, use natural lights – working near the windows will prevent you from turning on the light and consuming energy. Utilize the power of the sun.

Switch off the lights every time you leave the room even if it is just of a minute.

If you are using the 4-foot fluorescent lights, install reflective backings to maximize the light.

Switch to compact fluorescent lights. There are 4-watt minifluorescent lights and 40-watt fluorescent lights have the same illuminating effect.

Turn off all lights and appliances when not in use. Unplug unnecessary appliances like microwaves, television, stereos, computers, and VCRs if you are not using them. Also, unplug chargers and devices with bloc-shaped transformer on the plug. All of them consume energy when plugged in. Do not leave them on “stand-by” mode.

Look of Energy Star label when purchasing lighting product.

Use task lighting instead of lights that cover the entire room. For example, use lamp shades when reading and not the lights for your room.

Laundry

Washing your clothes cold will reduce washer’s energy consumption by as much as 90%. Air drying eliminates the energy use for machine drying.

Always do full loads whenever possible. If you are washing a small load, use appropriate water level and wash setting.

Refrigerator

Maintain a right temperature for your freezer and refrigerator.

Do not hold the refrigerator or freezer open. The energy consumption increases if the motor works endlessly just to maintain the temperature of the refrigerator and freezer.

Check for leaks and cracks in the gasket. Make sure that your refrigerator is completely sealed to maintain the temperature inside.

Insulation

Heat loss happens when your house is not properly sealed. Use sealants or weather-stripping on windows.

Make sure that air cannot escape or enter in to the pipes, doors, walls, floors and ceilings. A properly insulated home saves as much as 10% in electric bill.

In a typical household monthly electric bill, 44% goes to the heating and cooling systems; 33% goes to lighting and other appliances; 14% goes to heating the water; and 9% goes to the refrigerator. Take note of this power distribution to know where exactly you can maximize your saving.

The Importance Of Waste Management

Archeological evidence said that humans had a way of managing their waste even before landfills and incinerators were developed. In many archeological sites, dumping pits were discovered where early people were believed to throw in their waste. In the course of history, waste regulations were enacted. This suggests that waste management is not a modern principle but in fact a natural response to existence.

Humans naturally know what to do with their waste as evidenced by the instituted waste management systems in the pre-modern and modern forms. However, along with global industrialization and population explosion, waste production blew out of proportion, endangering the environment and threatening humans and other living things. With the environmental issues raised here and there, there seems to be a need to remind humans of the importance of waste management.

Education and awareness campaigns play a great part here. Not all people after all are aware that the one piece of waste material they are sending to landfills or incinerators constitutes a greater threat to the environment. Presently, calls to recycle and waste reduction are widely active. And various projects and campaigns are launched everyday, adding more noise to the earlier advocacies on proper waste management.

The good news is that a good number of the population is increasingly becoming aware of the importance of waste management and is getting involved. However, more need to be tapped. There are still who remain passive. This segment of the population probably knows that proper waste management benefits the Earth and consequently everyone and everything living in it. But only vaguely. The finer and more intricate details are probably not known to them.

Waste does a lot of things. When brought to the landfills, they emit greenhouse gas in the form of methane. Although methane can be used to make energy, it is generally hazardous to health. Wastes buried in landfills also tend to leach chemicals that can contaminate groundwater. Wastes can be incinerated, though. The problem with incinerators, however, is that they also produce greenhouse gas and other forms of toxin such as dioxin. Dioxin is found to cause cancer. Whether waste is brought to a landfill or incinerator, it seems like it is a potential source of pollution and threat to health.

Although indirectly, waste causes resource depletion. This is due to the common buying pattern: buy, throw, and then buy again. As the waste piles up high, the demand for more products also rises, almost exhausting the natural resources. This has a spiral effect, mainly involving threats to biodiversity, deforestation, pollution, and other environmental problems.

Waste management can be part of the solution in two ways: one is through waste reduction, and two through recycling. Consistent waste reduction and recycling activities mean there will be less waste materials to be sent to landfills and incinerators. As such, the emission of greenhouse gas and other forms of pollutant will be reduced by a large percentage. Reusing and recycling of used items will also result in less production of new products. And this helps in the conservation of natural resources.

There is a great need in understanding the importance of waste management because unless it is acknowledged by all people, waste management efforts will not progress to further heights.

Solar Power for Homes and its Benefits

Modern technology can do a lot of great things. One is the use of solar power for homes. Did you know that you can enjoy many benefits from using solar power? Solar panels can now be created at home by simply following comprehensible do-it-yourself instructions. Building power systems is no longer very expensive these days and it’s also not as hard as you think.

With the increasing demand for solar powered homes, you can now find a wide range of DIY projects in the market. The reasons why many homeowners are now choosing solar power for their homes is because they want to help in the persistent global warming crisis and electric bills cost a lot these days.

The electricity supplied in modern homes usually comes from different power plants. These power plants use fossil fuels and so the electric charges are greatly dependent on the prices of natural gases and crude oil. Fossil fuels are also depleting. There is a high demand for electricity but the resources have decreased greatly. In this kind of situation, the electrical costs will still continue to increase. The solar power for homes is an excellent answer to the problem.

By using fossil fuels, the problem with global warming will become worse. Harmful gases are emitted by the fossil fuels to produce electricity. If you don’t want to contribute to the environmental problems any further, why not use solar power for your home now?

Several years ago, the solar cells were really expensive and inefficient. Back then the solar cells were quite inefficient since they can’t convert 100% of the rays of the sun into electricity. Most solar cells can convert only 10-25%. In the year 2003, a new product was introduced and it was called photovoltaic cell. The new cell can convert 36% of the rays into usable electricity. The cells were also affordable. The modern sunlight technology is now widely available and even ordinary homeowners can take advantage of it.

The solar power kits are available worldwide. You can purchase them in online stores or you can also shop around in local stores. If you’re unsure, it would be best to shop online. There you can find several reputable sellers and manufacturers of solar power kits.

The solar power kits provide step by step instructions on how to assemble the different materials. Hardware stores usually sell the different parts of the solar power system. If create your own solar power system, you will only spend about $200 and it already includes the guide. With such a small investment, you can already benefit from solar power for many years. You’re not only saving money but you’re also helping in saving the planet.

Renewable and clean energy sources are in great demand these days. The homes of the future are now possible in today’s modern world. You can start with small projects and work your way up. For instance, you can first work on the outdoor lighting first and if it proves to be beneficial, you can do another project.

Don’t cut off the existing electrical supply especially if this is your first time to do solar power projects. Just use it as a supplement so that you can lessen your electricity consumption. Start with your DIY solar power project and light your home using the sun’s energy.
