Summary: | CalCOFI 1810SR sailed Oct 14 2018 from Nimitz Marine Facility, Pt Loma on SIO RV Sally Ride with 21 scientists, technicians, biologists, & volunteers. 75 stations were scheduled this autumn cruise from 14-29 Oct, San Diego to Pt Arguello. All stations were occupied except one - sta 85.4 35.8 Pt Dume SCCOOS - which was dropped due to a lack of shiptime. This was scheduled in the optimal seasonal date window for an autumn cruise. The weather was excellent for the first week of the cruise and good for the rest of the cruise. |

Please note that the anomalies are based on 50-year harmonics (1949-1999) and these data are 1m binavg Seasoft-processed CTD data that have not gone through thorough quality control checks or bottle corrections. They are presented to give a general impression of current conditions. Final data plots will be published after all data are processed.
