| 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. |
