Project: | CalCOFI 1711SR (UNOLS SR1717) |
Summary: |
CalCOFI 1711SR sailed from Nimitz Marine Facilities (MarFac), San Diego at 0800 09 Nov 2017 with 17 scientists, technicians, & volunteers. 74 of 75 scheduled stations were successfully occupied; one station was missed due to naval operations precluding our timely occupation of sta 90.45. A personnel exchange mid-cruise caused a major change in the station order. On Line 80, sta 80.55, we were restricted from station due to a NOAA weather satellite missle launch so we continued west to 80.60. Sta 80.55 was occupied on our southward transit to Line 87. Refer to cruise track map for actual cruise track and station order. RV Sally Ride returned to San Diego at ~1430 24 Nov 2017 & due to the Thanksgiving holiday, offloading was postponed till 0800 Monday 27 Nov. |

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.
