Survey : CLIO/7/1961 (part of CEFAS Historic surveys)

This survey was undertaken by Cefas as part of the CEFAS Historic surveys;

Station and biological data collected during research surveys carried out by 
Cefas (formerly Directorate of Fisheries) in seas around the UK, mostly in the 
North Sea, since 1902. The survey hauls are not laid out systematically as a 
grid, as in current International Bottom Trawl Surveys (IBTS) and are widely 
distributed over (especially) southern and central North Sea areas. Gears and 
protocols were not standardised throughout, due to the long term nature of the 
series. Surveys took place in each season. Data are lacking for the periods of 
both World Wars. In some periods (e.g. the early 1900s), all species caught 
were recorded, whereas in other periods (e.g. 1920s-30s), only the key 
commercial species (e.g., Plaice, Sole and Cod) were recorded systematically. 
Note that some surveys targeted particular species (notably Plaice).

Survey took place between 27/03/1961 and 12/04/1961 on Clione

Equipment used during this survey :


-   Modified Otter Trawl V.D. Trawl
-   Otter Trawl Dutch Herring Trawl IYFS Spec.

Survey operations were undertaken on 12 stations

Biotope (macrofaunal assemblage) map and associated confidence layer based on grab and core data from 1976 to 2020

Two vector (.shp) files are provided. The first, (*macro_assemblages.shp*) 
shows the modelled (random forest) macrofaunal assemblage type based on a 
clustering of abundance data from the OneBenthic database (see 
`https://sway.office.com/HM5VkWvBoZ86atYP?ref=Link`_). The second file, 
*(macro_assemblages_confidence.shp)* shows associated confidence in the 
modelled output, with darker shades (high values) indicating higher confidence 
and lighter shades (lower values) indicating lower confidence. Both layers can 
be viewed in the OneBenthic Layers tool *(
`https://rconnect.cefas.co.uk/onebenthic_layers/`_)*, together with further 
details of the methodology used to produce them.

Survey : EHOLT/05/1956 (part of Historic Arctic Survey Series)

This survey was undertaken by Cefas as part of the Historic Arctic Survey

*Gadus morhua* (Atlantic Cod) stocks in the Barents Sea are currently at 
levels not seen since the 1950s. Causes for the population increase last 
century, and understanding of whether such large numbers will be maintained in 
the future, are unclear. To explore this, we digitised and interrogated 
historical cod catch and diet datasets from the Barents Sea. Data includes 
temporal and spatial information, cod catch data and length distributions, and 
hydrographic data.
