Crew member Peter Wall recovers the Continuous Plankton Recorder (CPR). Whenever the ship stops, the CPR must be brought back on board. This instrument records for 450 nautical miles, and we have only gone about 100 since we started this new silk (where the plankton get caught). Scientists will note the location on the silk where the CPR silk stopped when it exited the water, and note a new position further along where the sampling will resume.
