Images: Voyage Takes a Census of Life in the Sea

Peter Wiebe, senior scientist in the WHOI Biology Department and chief scientist on the Census of Marine Zooplankton cruise, helps launch the Multiple Opening Closing Net Environment Systems Sampler (MOCNESS) from the deck of the NOAA research vessel Ron Brown, to sample ocean life at several depths. The cruise, part of the Census of Marine Life project, brought international experts together to find Atlantic Ocean animal plankton species and identify them using both taxonomic and molecular DNA methods.

One of the MOCNESS nets rises out of the ocean, with its multiple net ends trailing. Each separate net samples a different ocean depth and is controlled by computer from the ship. (Photo by Ken Buesseler, Woods Hole Oceanographic Institution)

The large MOCNESS, with a 10-meter-square mouth, a heavy metal frame, and nine separate nets, requires many hands to pull aboard after an hours-long tow through the ocean. (Photo by Larry Madin, Woods Hole Oceanographic Institution)
