The IKMT (Isaacs-Kidd Midwater Trawl)

This is the net we've been using most of this cruise to gather
zooplankton (a broad category which includes krill, amphipods, copepods,
some fish eggs and larvae, and many other taxonomic classes). Today
we're preparing to launch the Tucker Trawl which is a larger and more
complicated system. It has three nets that can be remotely opened and
closed at various depths.
