2020 Cruises
| Summary: | CalCOFI 2010SR sailed on RV Sally Ride at 0800PDT 11 Oct 2020 from Nimitz Marine Facility San Diego. 71 of 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. Two expendable wave measuring drifters 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 24 Oct 2020 0800PDT. |

| 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.

| Summary: | CalCOFI 2001RL sailed on NOAA FSV Reuben Lasker at 1400PDT 04 Jan 2020 from Tenth Avenue Marine Terminal San Diego. 104 of 104 science stations were completed. CTD casts and various net tows were completed at each science station. Underway visual observations of marine mammals were conducted while under transit and sonobuoys deployed before stations as the acoustic component. Other underway science included continuous pCO2/pH and meteorological measurements. The cruise ended in San Francisco at Pier 30/32 on 26 Jan 2020 1300PDT. |
