The survey data consist of: 1) one time series from 1984-2002 (October/November) using R/V Michael Sars and the Campelen-trawl; 2) a point estimate for 2003 (October) as R/V Michael Sars was taken out of service and substituted with R/V Håkon Mosby, whose winches at that time were not powerful enough for the Campelen-trawl, resulting in the survey being conducted with the Shrimp trawl 1420; 3) a start of a potential new time series as the survey in both 2004 and 2005 was conducted in May/June with R/V Håkon Mosby using the standard Campelen trawl; and 4) one time series from 2006 until present (January/February), using R/V Håkon Mosby and the Campelen trawl. From 2017 R/V Håkon Mosby has been substituted with R/V Kristine Bonnevie. In 2016, there were technical problems with the survey trawl (unequal wire lengths of the trawl gear) and this year’s data are considered to be non-representative of the stock status.
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 2,633 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
