Seawater temperature, conductivity, pressure and salinity data offshore the Aquitaine Basin (XBT profiles and near-bottom moorings)

As part of the EPIGRAM project, two moorings, Aspex 9 and 10, equipped with temperature, conductivity and pressure sensors (Seabird microcat 37SM), were deployed offshore Aquitaine for a period of 2 years (2009-2011). The probes were calibrated in metrology and provide salinity values derived from calculations based on Fofonoff and Millard (1983) [Fofonoff, P. and Millard, R.C. Jr UNESCO 1983. Algorithms for computation of fundamental properties of seawater. UNESCO Tech. Pap. in Mar. Sci., No. 44, 53 pp. Eqn.(31) p.39. http://unesdoc.UNESCO.org/images/0005/000598/059832eb.pdf]. Several oceanographic missions ASPEX1, 2, 3 and 4, were dedicated to deploying and recovering these instruments. The frame of the mooring (Figure B) is laid on the seafloor with sensors at 0.5 m above it. Aspex 9 and 10 moorings are located at the continental shelf (at 148 m water depth) and continental slope (at 472 m water depth), respectively (Fig. A). Aspex 9 mooring recorded data from 18.07.2009 at 23:40:00 to 01.07.2010 at 09:18:00 (with a measurement every 120 seconds) and from 04.09.2010 at 23:30:00 to 10.08.2011 at 06:57:00 (with a measurement every 180 seconds). Aspex 10 mooring recorded data from the 18.07.2009 at 21:40:00 to 22.07.2010 at 23:18:01 and from 05.09.2010 at 01:20:00 to 10.08.2011 at 04:58:00 (with a measurement every 120 seconds). This ASPEX dataset can be downloaded from here: a zip file containing one .txt file with indications of recording time, location and water depth of the two moorings and four data files (one .txt file per mooring and per recorded period) with for each measurement the year (YYYY), month (MM), day (DD), hour (hh), minute (mm) second (ss) and pressure (P), temperature (T), conductivity (C) and salinity (S) values.

As part of the PAMELA project, 18 XBT (eXpendable BathyThermograph) probes (Sippican) were launched in 2013 (July to September) offshore Aquitaine Basin. Seawater temperature profiles were thus acquired through the water column from different locations at the shelf area (at 140 m water depth), the continental slope and the basin (at 1213 m water depth) (Fig. A). Some of these XBT profiles are accessible via the Coriolis platform (http://www.coriolis.eu.org/). The complete GAZCOGNE1-2 dataset can be downloaded from here: a zip file containing one .txt file with indications of time, location and water depth for the XBTs and 18 data files (one .txt file per XBT profile).

We should like to thank the captains and the crews of research vessels Le Suroît, Thalassa and Pourquoi pas ? and the ASPEX and GAZCOGNE Scientific Parties. The ASPEX1 to 4 surveys (https://doi.org/10.18142/245) were part of the EPIGRAM project dedicated to studying the physical processes of the Bay of Biscay and the Channel and were supported by the Agence Nationale de la Recherche (Grant ANR-08-BLAN-0330-01) and CNRS/INSU national programme LEFE/IDAO. The marine expeditions GAZCOGNE1 (http://dx.doi.org/10.17600/13020070) and GAZCOGNE2 (https://doi.org/10.17600/13030090) were co-funded by TOTAL and IFREMER as part of the PAMELA (http://dx.doi.org/10.18142/236) (Passive Margin Exploration Laboratories) scientific project.
