Summary: | CalCOFI 1911OC sailed on RV Oceanus at 1000PDT 04 Nov 2019 from Nimitz Marine Facility San Diego. 75 of 75 science stations were completed. CTD casts, secchi disk casts, and various net tows were completed at each science station. Underway visual observations of marine mammals were conducted while under transit. There was no acoustic component (i.e., no hydrophone array or sonobuoys) to this cruise. Other underway science included continuous pCO2/pH and meteorological measurements. The ship averaged >13 knots, allowing sufficient time to complete all 75 stations and return to San Diego before schedule on 19 Nov 2019 0800PDT. |

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.
