What Do Marine Biologists Use for Tools?
Marine biologists are scientists who study the plants, animals, and microorganisms that live in the ocean and other saltwater environments. To conduct their research, they rely on a wide range of tools and equipment. In this article, we’ll explore some of the most common tools and technologies used by marine biologists.
Surveys and Monitoring Equipment
Marine biologists use various equipment to survey and monitor marine ecosystems. Some of the most common tools include:
- Remote Operated Vehicles (ROVs): ROVs are unmanned underwater vehicles that are operated remotely from the surface. They are equipped with cameras, sensors, and manipulator arms, allowing marine biologists to collect data and samples from the seafloor.
- Autonomous Underwater Vehicles (AUVs): AUVs are similar to ROVs but are programmed to follow a specific route and collect data along the way. They are often used to map the seafloor and track changes in marine ecosystems over time.
- Acoustic Sensors: Acoustic sensors are used to detect and track marine life, such as fish and dolphins. They work by emitting sounds and measuring the time it takes for the sounds to bounce back off objects in the water.
- Benthic Landers: Benthic landers are equipment that is lowered to the seafloor to collect samples and data. They can be equipped with cameras, sediment samplers, and other sensors.
Sampling and Collecting Equipment
Marine biologists use various equipment to collect samples of marine life and habitats. Some of the most common tools include:
- Trawls: Trawls are large nets that are dragged along the seafloor to collect fish and invertebrates. They are often used to study commercial fisheries and to monitor the health of marine ecosystems.
- Crane Pulleys: Crane pulleys are used to lift heavy equipment, such as nets and lines, out of the water. They are often used in conjunction with trawls and other sampling equipment.
- Coring Devices: Coring devices are used to collect sediment and rock samples from the seafloor. They can be used to study the geology and chemistry of marine ecosystems.
- Diving Gear: Diving gear, such as scuba tanks and rebreathers, are used by marine biologists to collect samples and data while underwater.
Laboratory Equipment
Marine biologists use a variety of laboratory equipment to analyze the samples they collect. Some of the most common tools include:
- Microscopes: Microscopes are used to study the microscopic structure of marine organisms, such as plankton and fish larvae.
- Spectrophotometers: Spectrophotometers are used to analyze the chemical composition of seawater and sediment samples.
- Gas Chromatographs: Gas chromatographs are used to analyze the chemical composition of marine organisms, such as fatty acids and steroids.
- Freezers: Freezers are used to store samples of marine organisms and seawater for later analysis.
Software and Databases
Marine biologists use a variety of software and databases to analyze and manage their data. Some of the most common tools include:
- Geographic Information Systems (GIS): GIS software is used to create maps and analyze spatial data related to marine ecosystems.
- Database Management Systems (DBMS): DBMS software is used to manage and analyze large datasets related to marine ecosystems.
- Statistical Analysis Software: Statistical analysis software, such as R and SAS, is used to analyze the data collected by marine biologists.
- Web Mapping Tools: Web mapping tools, such as ArcGIS Online and Google Earth, are used to share data and visualizations with others.
Other Equipment
Marine biologists use a variety of other equipment to conduct their research. Some of the most common tools include:
- Satellite Imagery: Satellite imagery is used to study the physical and biological characteristics of marine ecosystems from space.
- Gliders: Gliders are unmanned underwater vehicles that are used to study ocean currents and circulation patterns.
- Buoys: Buoys are used to measure ocean currents, waves, and water temperature.
- Cables and Lines: Cables and lines are used to collect data from instruments, such as ocean current meters and sea floor landers.
