Summary: 1507OC Summer CalCOFI cruise on RV Oceanus; 08 - 25 Jul 2015; 71 stations (62 standard & 8 SCCOOS) successfully occupied. Stations 86.7 110, 83.3 110, 76.7 100.0, & 85.4 35.8 were cancelled to maximize remaining shiptime, reduced by ship equipment failures. No delays or station cancellations were due to bad weather or scientific equipment failures. All PRPOOS tows on lines 90.0 & 80.0 were performed but tows on lines 83.3 & 86.7 were cancelled. ~75hrs of shiptime were lost due to personal emergency and two separate ship equipment failures (refrigeration unit & seal to main generator cooling pump). The cruise was extended one day to help recover time & minimize station loss; originally, the ship was to return 24 Jul.
