People who study sea life are called marine scientists. People who worked in the oceans and watched how food was found were the first marine biologists. Most marine scientists today are researchers who study the lives of animals and plants that live in the ocean.
People have been interested in the ocean for a long time. Some explorers, like Charles Darwin, wanted to learn more about what was at the bottom of the ocean. They also tried to figure out where the food came from. Between the mid-1400s and the early 1900s, there was a time called the Age of Discovery. During this time, ocean-going ships were made and men with a sense of adventure were born. Sonar was a new scientific advance that was made during World War II. Sonar used sound waves sent from a ship to outline the shape of something in the water column. It was used by the military, and then marine scientists used it in their research. Marine scientists were able to study the creatures that live under the sea by using underwater cameras and TV. Because of these discoveries, new species have been found. The development of scuba diving gear was also a big step forward. Scientists could look at the plants and animals of the deep sea without having to leave the ship. An important part of a scientist's research is to find and keep marine organisms. Scientists can look at these animals to find out what they eat, what pollutants they are exposed to, and what kinds of ocean conditions they live in. Taking pictures of the specimens while they are still alive is also a good idea. For live collection, a simple plastic bag or wad of cloth can be used to hold and transport the specimens. If you can, seal the bag with a polyethylene lid. A traditional bail-top jar is harder to find than this. To save a living specimen, you have to freeze a small amount of formalin, which helps the animal feel calm. The right way to handle the animal will depend on its size and species. Marine mammals are a good way to tell how healthy water environments are. Scientists have also done a lot of research on them, including research on their bodies and how they act. Most of these research projects, though, are only happening in the United States and Europe. Compared to land mammals, we don't know much about how marine mammals react to sounds made by humans. We also don't know much about how different sounds, levels, and patterns of time affect them. Passive acoustic monitoring is the focus of the most recent research on marine mammals. Passive acoustic monitoring is a way to find out how marine mammals respond to outside stimuli. It involves collecting and recording sounds. Researchers can learn about how animals respond to key environmental factors by using a system of hydrophone arrays mounted on the sea floor. Population dynamics is also a popular area of study. This includes studying how a species reacts to different conditions in its environment and how the same individuals may change how they react over time. For this kind of research, different methods have been used, such as satellite tags, visual surveys, and passive acoustics. A marine scientist's salary depends on his or her skills, experience, and level of education. It also depends on who is hiring. Most of the time, a marine scientist makes more money than the average American. The BLS says that jobs for marine scientists will grow by 8% over the next few years. Marine biologists may also get bonuses based on how well they do their jobs. They can make anywhere from $8 to $91 an hour, depending on what they specialize in. They can also work on the job site or in a lab. One of their jobs is to analyze seawater and use seismic technology.
