CalCOFI research technician Dave Faber hangs on to a CTD rosette as gale-driven waves crash onto the deck of Scripps research vessel New Horizon on April 11. Rough seas that are expected to last the next few days have forced CalCOFI to skip collection at some of the stations off the California coast that researchers regularly visit to collect data. Seawater in the rosettes is sampled to measure data related to primary productivity at the base of the ocean food web. Photo: Jim Wilkinson
