CalCOFI 2007SR
| Summary: | CalCOFI 2007SR sailed on RV Sally Ride at 0800PDT 13 Jul 2020 from Nimitz Marine Facility San Diego. All 75 stations were successfully occupied. CTD casts and Bongo/PRPOOS net tows were completed at each science station. Underway science included continuous pCO2/pH and meteorological measurements. Four expendable wave measuring drifters and one radio buoy (made by high school students from Mt. Carmel HS Radio Club) were also deployed. Due to science personnel restrictions related to social distancing requirements, no Manta/Pairovet net deployments or primary productivity experiments took place. Additionally, underway science including CUFES (Continuous Underway Fish Egg Sampler) and visual/acoustic observations of marine mammals and avifauna were not conducted during this cruise. The cruise ended at Nimitz Marine Facility San Diego on 27 Jul 2020 1500PDT. |

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.
