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 02/02/1914 and 10/12/1914 on Aldeburgh Equipment used during this survey : - Otter trawl Codend catch Survey operations were undertaken on 7 stations 5 different species were caught on this survey Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk originator Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk custodian Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk distributor Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) data.manager@cefas.co.uk owner notPlanned Fisheries SeaDataNet P03 parameter discovery vocabulary 2011-03-25 revision Advice Management Benthos Crustacean Shellfish Freshwater Age Aquatic environment Catchment area Climate Coastal environment Deep sea Estuary Sea bed Species Weather GEMET, version 1.0 2008-06-01 publication Temperature of the water column SeaDataNet P02 parameter discovery vocabulary 2011-03-25 revision Species distribution GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Water column SeaVoX Vertical Co-ordinate Coverages 2010-05-18 revision Marine Environmental Data and Information Network MEDIN metadata record availability 2012-01-11 publication data.gov.uk MEDIN metadata record availability 2012-01-11 publication otherRestrictions noLimitations otherRestrictions Adherence to the Cefas Data access policy required.

Over the decades, at least 11 different Research Vessels (RVs) carried out surveys using different gear deployments and catch sampling protocols over time. Early, steam-powered vessels towed the trawl at a speed of approximately 2 knots, whereas in current, diesel-powered vessels this is standardised at 4 knots. The data constitute a highly valuable information source, however, owing to the above, data analysis and interpretation requires caution. Species and Gear code lists are available via the additional information source field. MEDIN 3.1.1
