View from the Bottom

John Beaton (center), a marine science technician with the Scottish Association for Marine Science looks on as a trawl-resistant “bottom lander” is deployed from R/V Knorr as part of the 2014 Summer OSNAP program. The lander is shaped to prevent it getting entangled in bottom fishing gear and equipped with an upward-looking acoustic doppler current profiler (ADCP) to measure the speed of water flowing above it. OSNAP, or Overturning in the subpolar North Atlantic Program, is an international program that is providing a continuous record of seawater, freshwater and heat moving toward the Arctic.
