Other Technology
This fish trap, designed by MBARI, brings deep-sea fish back up to
the surface alive. At MBARI, oceanographers and marine biologists
work with engineers and machinists to create unique devices like this one.
Many marine biologists at MBARI study DNA and other genetic material
from deep-sea animals to find out how they are related and how they have
adapted to life in the depths.
Using MBARI's Video Annotation and Reference System, researchers can search for
virtually any animal or object captured in over 14,000 hours of video taken by
MBARI's remotely operated vehicles.
MBARI's autonomous underwater vehicles are used to map the seafloor, collect data
about ocean temperature, salinity, and chemistry, and to collect water samples.
They are programmed at the sea surface and then released to follow a predetermined
path through the ocean for up to 24 hours.
This "benthic rover," about the size of a compact car, crawls along the seafloor
taking photographs and measuring the amount of oxygen consumed by small organisms
that live in the sediment. This will help researchers figure out how animals in
the deep sea get enough food to eat.
