Water column temperature and salinity, Albatross IV survey, June, 1999

The NMFS/USGS survey of the southern part of Closed Area II was conducted in June, 1999 on 2 cruises: NMFS Albatross cruise ALB9905, June 2-9 (this cruise is also designated as USGS ALBA9933); and USGS R/V Connecticut cruise CONN9912, June 23. See the location map for the 1999 survey. For an overview of sampling strategy and methods for both cruises, see the cruise report file for Albatross cruise ALB9905 (ca21999alb9905rept.pdf). Study sites (1A, 2A, MMS1/2D, etc.) are part of a pre-determined grid of sites designed to sample the southern part of Closed Area II (south of 40o 30'N) and the area around its margins open to fishing that lies within approximately 2 nm of the western, southern, and eastern boundaries of Closed Area II. See files ca21999datatypes.pdf and ca21999datatypesB.txt for a tabulation of the kinds of data and the number of replicates collected at each study site. NMFS otter trawl, CTD, and benthic invertebrate stations use station numbers that are the same as the study site numbers (1A, 2A, etc.). USGS video/photo transect and sediment sample stations at the same study sites use a different numbering system (9906001, 9906002, etc.). See files ca21999datatypesA.pdf and ca21999datatypesB.txt for a list of NMFS and equivalent USGS station numbers. On the ALB9905 cruise, a suite of data was collected from each study site that included: 1) otter trawl sample of fish and epibenthic invertebrates; 2) benthic invertebrate samples from seabed sediment; 3) water column CTD (conductivity, temperature, pressure) profile; 4) 20-minute video/photo drift transect and sediment samples for texture and organic carbon analyses. In most cases, the sediment sample was collected at the end of the transect. On the CONN9912 cruise, later in June, only video/photo imagery and sediment texture samples were collected at five sites (3A, 3C, 4B, 5A, 5C) with the same sampling system that was used on the Albatross cruise. Of these 5 sites, only site 4B was sampled on the Albatross cruise (otter trawl and CTD cast only). Otter trawl and CTD stations are designated 1A, 2A, etc. and use the same numbering as the study sites. For locations of otter trawls, see files ca21999trawlstaA.pdf and ca21999trawlstaB.txt. For locations of CTD stations, see files ca21999datatypes.pdf and ca21999datatypesB.txt
