Sediment trap recovery. Sediment traps sit 350 meters deep and collect particles falling down through the water, which include dead algae and zooplankton and their fecal pellets. This constant marine "snowfall" nourishes the animals in the deep sea and pumps CO2 out of the atmosphere.
The left panel shows the yellow "hard-hat" floats that keep the mooring
array straight up-and-down in the water.
The right panel shows Eric and Greg bringing the trap itself up out of the ocean.
