Subject: [CCHDO] A20 325020210316 cruise doc needs correcting
Date: February 16, 2022 at 11:11:26 PST
Dear CCHDO, Jerry,
GO-BGC has determined that the cruise report for A20, 325020210316 is incorrect for the deployment of GO-BGC float 19107.
The cruise doc says the CTD associated with the float deployment is STNNBR 30. However, by matching date/time/lat/lon it appears that it is actually STNNBR 32. It is mentioned on the float deployment table in the cruise doc.
Susan Becker confirmed that float 19107 was deployed at STNNBR 32:
"I already had the HPLC and POC log sheets open ..... according to those float 19107 was deployed on station 32"
Thank you for correcting the cruise report that is online.
-sharon and GO-BGC
