Summary: |
CalCOFI 1601RL successfully completed all 104 scheduled stations, 95 standard & 9 SCCOOS. NOAA RV Reuben Lasker sailed Jan 6th, performing an acoustic calibration in San Diego Bay anchorage off Shelter Island. High winds and stormy weather Jan 6th postponed departure out of San Diego Bay until daybreak Jan 7th. The station order was standard south-north, west-east-west. After 74 southern stations were completed at 76.7 49.0, the CTD-rosette seawater sampling reduced from 24 to 12 bottles. After sta 70.0 51.0, most of the SIO scientific personnel disembarked in Monterey. The Pt Dume SCCOOS station at 85.4 35.8 was occupied last, during the transit home as sta 104. |

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.
