Evaporation correction was applied for cruises with salinity samples taken in plastic bottles that were measured more than 14 days after the cruise. The evaporation rate was calculated to be about 0.001 PSU per 15 days.
The following cruises were corrected.
HOT-2, subtracted 0.00092 PSU to all bottle salinities and recalibrated CTD data.
HOT-3, subtracted 0.00135 PSU to all bottle salinities and recalibrated CTD data.
HOT-4, subtracted 0.00114 PSU to all bottle salinities and recalibrated CTD data.
HOT-6, subtracted 0.00156 PSU to all bottle salinities and recalibrated CTD data.
HOT-7, subtracted 0.00135 PSU to all bottle salinities and recalibrated CTD data.
HOT-9, subtracted 0.00107 PSU to all bottle salinities and recalibrated CTD data.
HOT-10, subtracted 0.00092 PSU to all bottle salinities and recalibrated CTD data.
HOT-11, subtracted 0.00092 PSU to all bottle salinities and recalibrated CTD data.
HOT-12, subtracted 0.00405 PSU to all bottle salinities and recalibrated CTD data.
HOT-13, subtracted 0.00198 PSU to all bottle salinities and recalibrated CTD data.
HOT-14, subtracted 0.00128 PSU to all bottle salinities and recalibrated CTD data.
HOT-15, subtracted 0.00114 PSU to all bottle salinities and recalibrated CTD data.
HOT-16, subtracted 0.00085 PSU to all bottle salinities and recalibrated CTD data.
HOT-17, subtracted 0.00107 PSU to all bottle salinities and recalibrated CTD data.
HOT-18, subtracted 0.00099 PSU to all bottle salinities and recalibrated CTD data.
HOT-19, subtracted 0.00092 PSU to all bottle salinities and recalibrated CTD data.
HOT-22, subtracted 0.00178 PSU to all bottle salinities and recalibrated CTD data.
HOT-45, subtracted 0.00234 PSU to bottle salinities from casts at stations 10, 12, and 14.
HOT-53, subtracted 0.005964 PSU to bottle salinities from station 1 cast 3, and from station 3 cast 1.

Recalibrated HOT-140 CTD conductivity for a better fit.

Corrections to HOT-51 were applied due to recently discovered errors during the original data processing (see details in HOT-51 Salinity Corrections). CTD conductivities were recalibrated, and salinity bottles re-flagged.

Recalibrated HOT-124, station 2 casts 2 and 15 CTD conductivity for a better fit.

Recalibrated HOT-54 CTD conductivities for a better fit.

HOT-99, Station 2, Cast 15. Flagged CTD file for salinity glitches below 4438 dbar.

HOT-121, Station 2, Cast 15. Flagged CTD file for salinity glitches below 2780 dbar.

HOT-105 had problems during bottle salinity measurements due to failure of the bulbs that control the salinometer's bath temperature. This caused a drift in the salinometer measurements, but this problem was not identified when the salinities were originally processed. The bottle salinities were reprocessed correcting for drift, and the CTD conductivities were recalibrated.
HOT-31. Flagged CTD salinities from cast 17 at station 2 uncalibrated. This cast did not have salinity samples.
Recalibrated HOT-49, station 1 cast 1, and station 2 casts 1 and 18 CTD conductivities for a better fit.
