What Tools Does a Marine Biologist Use?
Marine biologists are scientists who study the plants, animals, and microorganisms that live in the ocean. Their research focuses on understanding the diverse ecosystems and interactions within marine environments. To collect data and conduct research, marine biologists rely on a range of tools and techniques. In this article, we’ll explore the most commonly used tools and technologies in marine biology.
Equipment for Collecting Biological Samples
One of the most important tools for a marine biologist is equipment for collecting biological samples. Some common examples include:
• Scuba gear: For collecting samples in the field, scuba diving gear is essential. Scuba divers can collect sediment cores, fish, invertebrates, and other samples using specialized equipment.
• Water samplers: Water samplers collect water samples for analysis. Types of water samplers include:
‣ Van Dorn sampler: For collecting large volumes of water
‣ Go-Flo sampler: For collecting smaller volumes of water
‣ Thermosampler: For collecting water samples for studying ocean chemistry
• Fishing gear: Anglers and commercial fishers use various fishing gears like nets, trawls, and traps to catch fish and other aquatic species.
Measurement and Analytical Equipment
Accurate measurement and analysis of data are crucial in marine biology. Marine biologists use various instruments and analytical tools to:
• Conduct field measurements: Marine biologists use:
‣ Current meters: To measure ocean currents and water movement
‣ Seismometers: To study ocean waves and seafloor earthquakes
‣ pH and temperature probes: To measure ocean chemistry
• Analyze water chemistry: Instruments like Titrators and pH meters measure the acidity and composition of seawater.
Lab Equipment and Software
The laboratory is an essential tool for marine biologists. They use a variety of equipment to:
• Process and analyze biological samples: Tools like microscopes, dissecting kits, and tissue grinders aid in processing and analyzing biological samples.
• Study microorganisms: Researchers use PCR (polymerase chain reaction), microscopes, and agar plates to study microorganisms and bacteria.
• Collaborate and analyze data: Marine biologists rely on software and tools for:
‣ Geographic Information Systems (GIS): For spatial analysis and visualization
‣ statistical analysis software: For data analysis and interpretation
Submersibles, Remotely Operated Vehicles (ROVs), and Autonomous Underwater Vehicles (AUVs)
Submersibles, ROVs, and AUVs are powerful tools for collecting data in deeper waters. These instruments enable marine biologists to:
• Collect samples at depth: Submersibles and ROVs collect biological samples from deeper water levels.
• Survey ocean floor terrain: Submersibles and ROVs conduct surveys of ocean floor terrain, allowing researchers to create detailed maps.
• Monitor water chemistry and marine life: AUVs and ROVs continuously monitor water chemistry and marine life in the water column and seafloor.

In conclusion, marine biologists use a range of equipment and technologies to collect, measure, and analyze data. The importance of each tool or technique depends on the research focus and specific study questions. By mastering these instruments, marine biologists contribute significantly to our understanding of marine ecosystems and the ongoing effort to conserve and manage the world’s oceans.
