Some Briliant Information That I Have Found

Dear Reader,

I have found the definition of Marine Biology: "marine biology is the study of life in the oceans and other saltwater environments such as estuaries and wetlands" (What is Marine Biology?)
I have also found that there are smaller fields that make up Marine biology. They include:

1. Microbiology (What is Marine Biology?)
2. Fisheries and Aquaculture (What is Marine Biology?)
3. Environmental Marine Biology (What is Marine Biology?)
4. Deep-sea Ecology (What is Marine Biology?)
5. Ichthyology (What is Marine Biology?)
6. Marine Mammology (What is Marine Biology?)
7. Marine Ethology (What is Marine Biology?)

I have also found out why some persons choose to study Marine Biology:

Health of the oceans/planet

1. Climate change
2. Pollution (toxicology, dumping, runoff, impact of recreation, blooms)
3. Coral reefs
4. Invasive species... (What is Marine Biology?)

Human health

1. Air quality
2. Dissolution of carbon dioxide... (What is Marine Biology?)

Sustainability and biodiversity

1. Overfishing
2. Endangered species
3. Impacts on the food chain... (What is Marine Biology?)

Research and product development

1. Pharmaceuticals
2. Biomedical applications
3. Alternate energy sources.... (What is Marine Biology?)

Personally, I don't know which reason I am motivated by to become a Marine Biologist, but I hope I will find what it is soon!

Also, believe it or not, there are different ways to study Marine Biology. They include:

1. Trawling - has been used in the past to collect marine specimens for study, except that trawling can be very damaging to delicate marine environments and it is difficult to collect samples discriminately. However when used in the midwater environment, trawls can be every effective at collecting samples of elusive species with a wide migratory range. (What is Marine Biology?)
2. Plankton nets - plankton nets have a very fine weave to catch microscopic organisms in seawater for study. (What is Marine Biology?)
3. Remotely operated vehicles (ROVs) - have been used underwater since the 1950s. ROVs are basically unmanned submarine robots with umbilical cables used to transmit data between the vehicle and researcher for remote operation in areas where diving is constrained by health or other hazards. ROVs are often fitted with video and still cameras as well as with mechanical tools for specimen retrieval and measurements. (What is Marine Biology?)
4. Underwater habitats - the National Oceanic and Atmospheric Administration (NOAA) operates Aquarius , a habitat 20  m beneath the surface where researchers can live and work underwater for extended periods. (What is Marine Biology?)
5. Fiber optics - Fiber optic observational equipment uses LED light (red light illumination) and low light cameras that do not disturb deep-sea life to capture the behaviors and characteristics of these creatures in their natural habitat.(What is Marine Biology?)
6. Satellites - are used to measure vast geographic ocean data such as the temperature and color of the ocean. Temperature data can provide information on a variety of ocean characteristics such as currents, cold upwelling, climate, and warm water currents such as the Gulf Stream. Satellites are also used for mapping marine areas such as coral reefs and for tracking marine life tagged with sensors to determine migratory patterns. (What is Marine Biology?)
7. Sounding - hydrophones, the microphone's counterpart, detect and record acoustic signals in the ocean. Sound data can be used to monitor waves, marine mammals, ships, and other ocean activities. (What is Marine Biology?)
8. Sonar - similar to sounding, sonar is used to find large objects in the water and to measure the ocean's depth (bathymetry). Sound waves last longer in water than in air, and are therefore useful to detect underwater echoes. (What is Marine Biology?)
9. Computers - sophisticated computer technology is used to collect, process, analyze, and display data from sensors placed in the marine environment to measure temperature, depth, navigation, salinity, and meteorological data. NOAA implemented computer technology aboard its research vessels to standardize the way this data is managed. (What is Marine Biology?)

Sorry, I don't have time to site my sources right now....so I will site the source I used on another blog post. I just wanted to state, so I don't get charged for plagiarism, I used the website: http://marinebio.org/oceans/marine-biology.asp

Hope
