Nearly all marine biologists spend at least part of their time doing research in the field, working in environments ranging from marshes or wetlands to the ocean. They use equipment including boats, scuba gear, nets, traps, sonar, submarines, robotics, computers, and standard lab equipment.Jun 25, 2019
Marine scientists use cameras, sensors, unmanned and manned submersibles, tags, aerial and underwater drones, and satellites to make observations about the ocean and the marine organisms that inhabit it.
There are three tools used to map the ocean floor, sonar, satellites, and submersibles. Sonar is a type of electronic depth-sounding equiptment made in the 1920’s.It is an acronym for sound navigation and ranging. Sonar is also known as echo sounding.
Today, buoys and water column samplers are used to monitor sea surface conditions and water quality factors, coring devices collect sediment samples, sonar helps create maps of the seafloor, and remotely operated vehicles (ROVs) allow us to safely and efficiently explore all parts of the ocean.
Some marine biologists wear casual Hawaiin shirts to teach their classes or conduct their research in their labs (with pants and safety glasses when they work in the lab, and some who dress up pretty nicely to teach their classes and then wear lab coats to do their research.
Basic Equipment Used in Biology Experiments
Marine biologists use computers in their research and writing. They use biostatistical programs to draw conclusions about marine populations. They use microcomputer programs for word-processing, entering data on a spreadsheet, putting together presentations and searching the Internet for research publications.
The seafloor can be studied indirectly with tools such as sonar. It can be studied directly using special vehicles. Some vehicles carry scientists and their devices to the ocean floor. … Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge.
Sonar. SOund NAvigation and Ranging—SONAR—is used to find and identify objects in water. It is also used to determine water depth (bathymetry). Sonar is applied to water-based activities because sound waves attenuate (taper off) less in water as they travel than do radar and light waves.
How do oceanographers measure the salinity of ocean water? Oceanographers measure the salinity of ocean water by using a hydrometer, a hydrometer set, a chemical test kit or a salinometer. A hydrometer is a quick test tool used in aquariums, and it works by reading the water density.
The first instrument used for deep-sea investigation was the sounding weight, used by British explorer Sir James Clark Ross. With this instrument, he reached a depth of 3,700 m (12,139 ft) in 1840. The Challenger expedition used similar instruments called Baillie sounding machines to extract samples from the sea bed.
The national average salary for marine biologists is currently $69,859 per year. This can be considered fairly competitive for a base salary. Many marine biologists also receive employee benefits besides their salaries, such as paid vacation time, paid sick leave, and 401(k) savings.
Here we take a look at seven of the most renowned marine biologists, identifying the reasons for their well deserved places on this list.
Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies–human medical research, plant research, animal research, environmental system research–at the cellular level or the ecosystem level or anywhere in between.
Among the many items that would be considered general lab equipment are pipettes, scales, centrifuges, Bunsen burners, freezers, hot plates, incubators, coolers, stirrers, water baths, and fume hoods – to name a few.
A microscope is one of the most common apparatus used in biology laboratories. It is mainly used to magnify small objects. To observe a specimen at a cellular level, a sample is taken and is studied at the micro-level with the help of a microscope.
What is a sediment trap and why do we use it? Sediment traps are containers that scientists place in the water to collect particles falling toward the sea floor. The traps collect tiny sediment or larger accumulations called marine snow- made up of organic matter, dead sea creatures, tiny shells, dust and minerals.

List three technologies for studying the ocean floor, and explain how they are used. Sonar, Geosat, and underwater vessels; sonar is used to determine the ocean’s depth by sending sound pulses from a ship down into the ocean.
Scientists could use IODP, sonar, Geosat, and deep flight. Name four ways that scientists study the ocean floor.
What types of technology are used to study the ocean floor? Sonar works by transmitting sound waves to the ocean bottom. A receiver intercepts the echo reflected from the ocean bottom and a clock measures the time it takes for the sound wave to travel to the ocean bottom and back.
Marine laboratories allow marine biologists to keep organisms alive and to work over long periods of time. They also may have state-of-the-art equipment for conducting scientific research or they may be simple field stations that provide a base for scientists who work in remote areas.
An ocean-bottom seismometer (OBS) is a seismometer that is designed to record the earth motion under oceans and lakes from man-made sources and natural sources. Sensors at the sea floor are used to observe acoustic and seismic events.
Currents are important in marine ecosystems because they redistribute water, heat, nutrients, and oxygen about the ocean. At the same time, currents inevitably sweep over and carry off living organisms.
