Technology

Nets and Traps are the mainstays of marine biology research. Most of the basic technology used for this research resembles the same nets and traps used by commercial fishers.
Tags and Telemetry are used to track the movement patterns of medium and large marine animals that they usually capture and put tags on then release them back into the wild.
CTDs (conductive-temperature-depth) is a device used throughout oceanography to collect basic data about the local water column.
Niskin Bottles are heavy-duty plastic bottles that open at both ends, with lids that snap shut on command- very useful for taking water samples at specific depths.
ROVs are attached to the boat- and the researcher on board- with a cable that transmits commands and receives data. These remotely operated vehicles are used in marine environments deeper than is safe for divers.
