SP2211 MAS MBC student cruise. Approximate tow time: 10:21-12:24 local time. Target depth ~500 m. Wire out: at least 1251 m. Bottom depth: 503 m. Endpoint reflects position at 55 m wire out. One or two decimal places in minutes value (three or four places in decimal degrees) is probably an appropriate level of precision, given ship speed and variation between displays. Otter trawl samples processed by all cruise participants. Many heart urchins and fragile urchins. Cruise science team: Greg Rouse, Charlotte Seid, Kiirah Green, Paul Proctor, Matthew Stephenson. 7.6 mi from shore; federal waters.
