Abstract Temperature and salinity were measured in situ at sea surface and at bottom during the BTS surveys from 1989 to 2006 (nevertheless, it should be noted that some of these data were not available for all years). Temperature and salinity were measured using a probe. These surveys give illustration of summer conditions.

Lineage The standard survey has a total of approximately 100 tows or stations (75 are in ICES division VIId,25 are in ICES division Ivc). Salinity and temperature were measured from surface to seabed using a probe attached on the headrope of the trawl. There is a lack of measuring in 1991, 1992, 1995, 1996, 1997 for surface temperature and surface salinity, and in 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999 and 2000 for bottom temperature and bottom salinity.
