2 NOAA/AOML TSG project description

3 sea surface salinity (SSS) Provides key information on the variability of global precipitation, evaporation, and the fresh water cycle. Is a factor in water mass formation and SSS variability can affect the intensity of the thermohaline circulation. Can be utilized to initialize climate forecast models, if salinity profiles are not available. Through Alkalinity improves is linked to the amount of dissolved CO 2 in the oceans. Will be used to validate and calibrate fields obtained from the SMOS and Aquarius satellite missions. Can be used to assess numerical model performances

4 NOAA/AOML Thermosalingraphs SBE 21: Oleander, Skogafoss, NOAA fleet. SBE 45 (micro TSG): RCCL Explorer of the Seas, Albert Rickmers, SAS Explorer, NOAA fleet. 2 cargo ships Atlantic Ocean. 1 cruise ship western North Atlantic, Caribbean Sea and Gulf of Mexico. 1 cargo ship Pacific Ocean. 1 cruise ship around the world twice a year. 15 NOAA shipsglobal.

5 NOAA/AOML TSG and SEAS installation set-up

6 AOML-TSG transects Skogafoss Oleander C. Waikato

7 Current NOAA/AOML-TSG transects currently maintained TSG transects Upcoming TSG installations: Semester At Sea M/V Explorer (around the world twice a year) Albert Rickmers (Pacific Ocean)

14 Skogafoss TSG transects transects SSS space-time diagram

15 Oleander TSG transects transects SSS space-time diagram Gulf Stream front

16 TSG temperatures are: C higher than the profiling float temperature, C higher than the XBT temperature and 0.09 C higher than the water sample. TSG Salinity values are in good agreement with concurrent observations: 0.05 lower than the float salinity and 0.07 lower than the water sample. Summary of TSG data QC statistical analysis (Skogafoss and Oleander) Issue: need of external temperature sensor

22 Continue transmission of data of RCCLs Explorer into the GTS. Initiate transmission of QCed (RT) data of cargo ships into the GTS. Initiate transmission of QCed (RT) data of NOAA fleet into the GTS. Test external temperature sensor in one cargo ship. Continue support of pCO2 systems. Collaborate with future satellite salinity missions. Initiate a sustained and strong collaboration with data centers, submission of QCed data to NODC and Coriolis. Have a strong participation within GOSUD. New TSG installations: M/V Explorer of Semester At Sea Albert Rickmers. Initiate tests with BUFR and Metadata. Science support. NOAA/AOML TSG plans Semester At Seas M/V Explorer
