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.
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.

Looking Into the Combination of GPS Systems and Weather Satellites
We know that weather satellites are used to track the changes in the earthâs atmosphere. As a result of this tracking ability various environmental changes have been discovered before they wreak havoc with our lives and the places where we live. These weather satellites are also used to inform us about the seasonal weather patterns and if there is any changes detected.
While the vast majority of us receive our weather information from television and radio stations there are some of us who can get this information from other sources. One of the newer ways of get weather updates for our locality is from gps receivers. As these receivers take their information directly from gps satellites the owners will be able to see how the weather is well in advance.
This knowledge about the weather is very useful to know if you are going out hiking, golfing, or even traveling in foreign countries. The information that is taken from weather satellites can be used by scientists and other professional who require this data. Currently to help the Meteorology department access more information and predict certain weather patterns there are specialized satellites that have been made.
These new weather satellites have specialized gps receivers that can detect various atmospheric conditions. These conditions like electron density, air density, moisture amounts and temperature for various regions can be collected daily. This accurate amassing of weather information helps weather scientists to predict the weather we will be experiencing.
These gps system enabled weather satellites were designed by and launched into orbit in April 2006. These six micro gps weather satellites are called the Constellation of Observing System Meteorology Ionosphere and Climate. The shortened form is known as COSMIC. Due to this collection of weather satellites and the technology of the global positioning satellites the various changes that are seen in the weather can be gathered quickly.
Based on these observations and the data that is provided the various weather departments can inform the general public about the type of weather that they can expect to see in their locality. The predictions that are made from the gps data allows the forecasting of the weather for about a week to be made with some accuracy.
Technology is always advancing. The ways that we use the technology can help to enhance the quality of our lives. One of the more important ways that technology can help is by predicting the weather.
To this end the gps systems that are in place have their roles to play. The combination of these gps systems and the weather satellites allow us the chance to enjoy the great sunny weather when we are given this great news. Without these weather satellites we would need to guess what type of weather we will have to face throughout the day.

Melting Arctic Sea Ice and Global Warming Hype
There can be no dispute that the ice over the Arctic is melting pretty fast. Satellite pictures clearly show the extent of the decrease in Arctic ice during the last several years. In fact, observations from instruments on the ground, balloons, and satellites indicate that the Arctic is warming much faster than the rest of the planet.
Last year’s seasonal ice shrinkage set records, reaching a September minimum of 2.6 million square miles, some 23 percent smaller than the previous record, set in 2005. If it sets another record this year, it would mark the fifth season of record declines since 1998.
In fact, preliminary data in June 2008 from University of Colorado researcher Sheldon Drobot does show that the vast expanse of ice at the top of the world is some 55,800 square miles smaller than it was on the same date last year.
The proponents of man-made global warming now point to the melting Arctic sea ice as proof that the planet is in immediate dire peril. Their climate models show that the Arctic sea ice is melting nearly three times faster than global warming computer models had previously projected.
Of course, melting Arctic Sea ice linked to the warming of the planet seems like an easy public relations correlation to make. Ice melts when temperatures rise. Arctic temperatures are rising fast apparently due to man-made global warming. The faster the ice melts, the faster the impact on the planet. So, everyone needs to spend more money and change behavior to eliminate CO2 gas to save the planet.
It all seems so logical until you think about it for awhile and do some research. Then, it really begins to not make much sense. Ultimately, I find that when things don’t make sense then they are usually not true. Here is what bothers me about melting Arctic sea ice caused by man-made global warming from an increase in CO2 gas.
First, no study has ever directly linked the increase in global temperatures of the last several decades with melting Arctic ice. There is no scientific evidence of a direct connection, only media hype. In fact, with the climate projection models predicting only one third of the Arctic ice melt that is actually occurring, then maybe another reason outside of global warming is really at work.
Next, there has been a record melt in Arctic ice each year since 1999. However, the average global temperature has not increased and has actually started to decrease in the last few years while that Arctic ice has been melting at an increased pace. Ice melting faster when the planet’s actual average temperature is going lower? Doesn’t seem to make much sense, does it?
Now, consider that in 2008 ice between Canada and southwestern Greenland reached its highest level in 15 years according to Denmark’s Meteorological Institute. The Institute used satellite images to track the southward expansion of the ice.
In fact, on a global basis, NOAA had this to say about world sea ice in April 2008. “Global sea ice reached levels that were “unprecedented” for the month of April in over 25 years. Levels are the third highest (for April) since the commencement of records in 1979, exceeded only by levels in 1979 and 1982.”
So, if global warming is creating melting Arctic ice, then why is ice not melting everywhere? In fact, the world had more global sea ice in April 2008, than it had for over the last twenty five years. Again, if it doesn’t seem to make much sense, it probably is not true.
So, the actual reason for melting Arctic ice may well have nothing to do with global warming. There have been several recent studies and discoveries in the Arctic that would suggest as much.
Recently, a team of scientists led by Dr. Robert Sohn of the Woods Hole Oceanographic Institution in Massachusetts got a first-ever glimpse of the ocean floor (13,000 feet) beneath the Arctic pack ice. Indeed, they were astonished with what they saw.
Massive volcanoes had risen from the ocean floor deep under the Arctic ice cap, spewing plumes of fragmented magma into the sea. The eruptions took place in 1999 along the Gakkel Ridge, an underwater mountain chain snaking eleven hundred miles from the northern tip of Greenland to Siberia.
Remember, that the record Arctic sea ice melt began in 1999 the same year as these volcanic eruptions began on the ocean floor. The truth is if you overlay the area of melting Arctic sea ice over the area of these massive volcanic eruptions on the ocean floor, a compelling circumstantial case can be made that volcanic eruptions may indeed be the cause of Arctic ice melt.
Other studies also indicate that global warming may not be the cause of melting Arctic sea ice. Last year, a team led by Son Nghiem of NASA’s Jet Propulsion Laboratory, in Pasadena, Calif., studied trends in Arctic perennial ice cover by combining data from NASA’s Quick Scatterometer (QuikScat) satellite with a computing model based on observations of sea ice drift.
The conclusion of the NASA team was as follows: “Unusual atmospheric conditions set up wind patterns that compressed the sea ice, loaded it into the Transpolar Drift Stream and then sped its flow out of the Arctic”. So, in effect, polar wind patterns changed and blew the sea ice further south to warmer waters leading to the record Arctic ice melt.
The fact is that there is so much that is unknown about how our climate changes over many thousands of years of time. This lack of knowledge makes it very easy for environmental alarmists to use melting Arctic ice and blame it on global warming due to a man-made increase in CO2 gas.
The point is that the cause of all that melting Arctic sea ice may have many different explanations. Indeed, melting Arctic Sea ice may well turn out to be just more misguided man-made global warming hype.
