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.
They also use computers to write programs that simulate natural processes and analyze data. They must know computer-programming languages and understand how to use software to conduct original research.
They also use laptops on board boats to chronicle data and findings as they conduct their research. Work Job Search Researching Jobs. By Jennifer Alyson. Boats Most marine biologists could not do their job without specially equipped boats. Submarines Some marine biologists use small submersibles to go to the ocean floor.
Cameras Marine biologists may use waterproof cameras and video cameras to catalog marine life and their habits. And if, by colliding with Earth , they added the amount of material some scientists suspect, such bodies could easily have delivered oceans' worth of water.
Abdenacer Moja Explainer. What technology is used to explore oceans? Who was the first person to reach the deepest part of the ocean? At p. ET Sunday a.
His depth on arrival: 35, feet 10, meters —a figure unattainable anywhere else in the ocean. Audria Heidebrunn Pundit. What is the most important topographic feature of the ocean floor? Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots. The basins also contain a variable amount of sedimentary fill that is thinnest on the ocean ridges and usually thickest near the continental margins.
Aizane Ahrouch Pundit. Who is a famous marine biologist? Jacques-Yves Cousteau. Stefcho Pailos Pundit. What skills do I need to be a marine biologist? A marine biologist needs:. An affinity with the marine environment and an interest in aquatic life.
Excellent numerical and statistics skills particularly sought by employers Practical fieldwork skills. Patience and good observation skills. Excellent teamwork and personal communication abilities. Gertrude Morejon Pundit. Is a marine biologist a scientist? Marine biology is the study of marine organisms, their behaviors and interactions with the environment. Marine biologists study biological oceanography and the associated fields of chemical, physical, and geological oceanography to understand marine organisms.
Kostadinov Eichl Teacher. What are the subjects for marine biology? AS and A levels: Biology is the most important Science you need to take, with Chemistry being a close second. Maths , Geography, Computing or Psychology can also be useful subjects.
Whatever you choose, at least two Sciences are recommended if you would like to go on to study Marine Biology. Nickolas Alvaredo Teacher. What are the different jobs in marine biology?
Types of marine biologist. Shazia Zimmermans Teacher. What do microbiologists do? They must mesh with ships' winches and cranes and be of a size and weight manageable on the wet, unsteady, windswept deck of a research vessel. At the same time, they must be very precise.
Some of the tools oceanographers employ are described here. The smaller ones, perhaps a meter long, may be towed briefly in near-surface waters. The largest multiple opening-closing variety consists of a great metal frame carrying as many as 20 nets and an environmental sensing array that sends information back to the ship's laboratory, where biologists signal the nets to open in sequence as they observe temperature, depth, salinity, and other characteristics of the water column.
Such a net tow may last many hours. When the samples come aboard the ship, some may be examined immediately under microscopes in the ship's lab, animals may be dissected or analyzed for clues to their food sources or exposure to pollutants, and other samples may be preserved for further work in shore-based laboratories. In other techniques, a series of samples may be collected by a device at the small end of a single net, or a silhouette photographic system may take pictures of the animals collected.
Some animals, such as gelatinous zooplankton, are collected by scuba divers, who gently place specimens in glass jars to avoid damaging their fragile bodies.
These are maintained in aquaria in the ship's laboratory and studied at sea, as they cannot be grown or preserved intact. Many techniques developed by divers to handle fragile plankton have been redesigned for use with submersibles. Bottom trawls, dredges, and coring devices are used to collect animals that live in or on the sediments and rock bottom.
Another technique involves placement of trays of sterilized sediment back on the deep-sea floor to study colonization rates and animal distribution. New methods for this kind of sampling are being developed in order to reduce station time. The largest water bottles, called Gerard barrels , collect liters.
Aboard the ship, a flow cytometer may be used to analyze particles in the form of single-celled organisms for optical properties indicative of their physiology and structure. Another is the expendable BathyThermograph XBT , a temperature probe released on a weighted copper wire that unreels to record temperature and depth while the ship is underway. At the instrument's maximum depth of 1, to 6, feet to 2, meters , the wire breaks.
Data from the 10, XBTs U. Other profilers, including some that measure sound velocity and microturbulence, are dropped from a ship to free-fall to the seafloor, adjust ballast, and return to the surface for retrieval. They provide data from both descent and ascent. Ship-wire-deployed and free-drifting water sampling and incubation instruments measure plant nutrient uptake, bacterial incorporation of dissolved organics, and plankton feeding rates.
Specially designed water bottles enclose a sample, and then dispense chemical labels useful for a variety of measurements. Such floats have been tracked for years by moored sound receivers to provide a long-term look at ocean currents.
Trajectories of individual floats show how the water moves horizontally, and trajectories of groups of floats show how the water is mixed by eddies. This information is important for understanding how water tracers and pollutants are transported by the ocean.
More recently, the sound sources have been moored while the floats act as receivers, surfacing at the end of an approximately two-year lifetime to report their data via satellite to a shore station. Other floats drift for two months, surface to transmit data to a satellite, and descend again for another two months of data collection.
They can repeat this process for up to five years.
