This information is only available from in-situ measurement. However this information is acquired all around the world and not easily available to the operational users. Therefore, the Mersea IN-SITU ThEmatic Portal (TEP) , by connecting to a lot of international networks, collects, controls and disseminates the relevant in-situ data to Mersea operational users. Each day, a new release of the product is issued containing the observations which have never been disseminated in previous release or have been updated. A sliding window of the past 3 months of product is available at the In-Situ Each TEP. No Archive of the product releases is insured at the In-Situ TEP, only the individual observations are archived.
Processing information : the product is the homogeneous aggregation of observation data coming from various in-situ sources, quality controlled according to standardized procedure. the duplicate removal have been processed.Description of observation methods / instruments :

1. profile data from ARGO profiling floats, CTD and XBT from research vessels or vessels of opportunity, mooring from various projects (animate, tao/triton/pirata) and profile data from GTS ( Global Telecommunication System in BUOY, BATHY and TESAC format).
2. along the track data from thermosalinograph, ARGO profiling floats and drifting buoys available on GTS network.

The measured parameters, depending on the data source, are : temperature, salinity, dissolved oxygen or carbon...
The reference level of measurements is immersion (in meters) or pressure (in decibars).
Quality/accuracy/calibration information : On each profile or underway data individual automatic tests (peak detection, ....) and statistical tests (comparison with climatology and neighbour measurements) are performed. On doubtful data visual control by ocean physics expert is performed. As a result of these tests, quality control flags are assigned to each measurement and included in the product.
Suitability, Expected type of users / uses : The product is designed for assimilation into operational models operated by the Mersea forecasting TEPs. These users need data aggregated and quality controlled in a reliable and documented manner. As the different releases of the product are not archived by Mersea In-Situ TEP, users have to manage their own in-situ data archive if they need it. ]]> CORIOLIS codac@ifremer.frhttp://www.coriolis.eu.orghome web pagehttp://www.mersea.eu.org/images/logos/coriolis.gif In-Situ TEP codac@ifremer.frhttp://www.mersea.eu.org/1-in-situ.htmlhome web page In situ datasets Along track (observations) TEMP: Temperature of the water column PSAL: Salinity of the water column DOXY: Dissolved oxygen parameters in the water column PCO2: Partial pressure (pCO2) and fugacity (fCO2) of carbon dioxide in the water column moles_of_oxygen_per_unit_mass_in_sea_water,mol kg-1,CF sea_water_salinity,1e-3,CF sea_water_temperature,K,CF surface_partial_pressure_of_carbon_dioxide_in_sea_water,Pa,CF http://www.mersea.eu.org/images/products-quicklooks/CORIOLIS.jpg product QuickLook JPEG N/A degree -180.0 180.0 -90.0 90.0 vertical : Water column, geographical : Global scale, temporal : Near real time, -6000 0 meters 2005-01-01 global ocean -90,180 90,180 90,-180 -90,-180 -90,180 north east atlantic 48.27,-35 63,-35 63,7 59,11 57.44,10.30 53.49,9.23 48.27,-1.24 48.27,-35 arctic 63,-35 90,-35 70,30 63,7 63,-35 baltic sea 66.20,20 66.20,26 59.5,30.19 53.49,20.55 53.49 9.23 57.44,10.30 59,11 66.20,20 mediterranean sea 35.47,-5.54 36.15,-5.54 46,5 46,15 40.25,26.41 38,38 30,35 29,19 35.47,-5.54 temporal resolution : N/A Quality control http://www.coriolis.eu.org/cdc/argo/argo-quality-control-manual.doc 2004 User's manual http://www.coriolis.eu.org/cdc/argo/argo-dm-user-manual.pdf 2004 Quality control http://www.coriolis.eu.org/cdc/argo/argo-quality-control-manual.doc 2004 User's manual http://www.coriolis.eu.org/cdc/argo/argo-dm-user-manual.pdf 2004 Quality control http://www.coriolis.eu.org/cdc/argo/argo-quality-control-manual.doc 2004 User's manual http://www.coriolis.eu.org/cdc/argo/argo-dm-user-manual.pdf 2004 partner 4326
