Loading: |
Early pre-holiday break loading: 19 - 21 Dec 2016 Tuesday, 04 Jan 2017 - Wednesday, 05 Jan 2017 morning; 10th Ave Marine Terminal, San Diego, CA |
Offloading: | 30 Jan 2017; 10th Ave Marine Terminal, San Diego, CA |
Partiicpant Forms: | NOAA Medical Forms - required for all cruise participants sailing Jan 05 2017 |
Ship: | RV Reuben Lasker |
Station plan: | 104 Stations (95 CalCOFI + 9 SCCOOS) were scheduled and 83 (74 CalCOFI + 9 SCCOOS) were successfully occupied due to severe weather Jan 20-24. Green transit is Leg I returning to San Diego; Blue transits are Leg II N & S transits. Red stations were CUFES surveyed only during the transit south. |

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.
