  • An important task undertaken this year was to define sub-regional areas of the ICES greater North Sea eco-region. The sub-regional areas correspond to meaningful eco-logical units whose boundaries are defined by strong gradients in their physical oceanography, such as changes in depth, sediment transport, salinity, oxygen and currents. The four sub-regions of the ICES greater North Sea eco-region are; i. North-ern North Sea, ii. Southern North Sea, iii. Skagerrak and Kattegat, and iv. English Channel

  • The dataset includes information about spatial distribution and abundance of fish eggs and larvae in the North Sea based on the data from the North Sea Cod and Plaice egg surveys (2004, 2009). The survey is later succeeded by the MIKey Net Survey in the North Sea

  • Acoustic mapping of the seabed of the Menai Strait. Local classification, seperated into acoustic ground characteristics: hard/soft and smooth/rough. Swellies.

  • The purpose of this study was to re-survey six locations on the rocky shore within the Teesmouth and Cleveland Coast European Marine Site which had originally been surveyed in November 2003 in order to make an assessment of these habitats as a food resource for shorebirds. The original survey also provided data on the biotope composition and biodiversity of the site in order to inform Natural England on the status of the large shallow inlets and bays feature of the site.

  • Mapping the distribution of maerl in South Uist, Western Isles was a collaborative study between Scottish Natural Heritage and the BioMar Programme. The survey used acoustic techniques, video drops, ROV, grab samples and diver surveys. The result was a map of predicted biotope distribution.

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Portuguese Ground Fish trawl survey.

  • VME data portal is a central portal for data on the distribution and abundance of Vulnerable Marine Ecosystems (VMEs), (and organisms considered to be indicators of VMEs) across the North Atlantic that has been set up by the Joint ICES/NAFO Working Group on Deep-water Ecology (WGDEC) and is hosted by ICES. The database is comprised of 'VME habitats' and 'VME indicators' records. The VME database serves multiple purposes; ICES uses it for providing scientifically-robust advice on the distribution of VMEs and recommending possible management solutions such as bottom fishing closures within NEAFC (North East Atlantic Fisheries Commission) waters to protect VMEs.

  • Emu Limited was commissioned by Natural England to carry out an acoustic and ecological survey of the subtidal zone (areas below the Mean Low Water mark) within the Solent Maritime Special Area of Conservation (SAC). The remit of the survey was to produce data and maps characterising the overall subtidal seabed surface topography, surface sediment composition and the main subtidal biotopes which fall within the Solent Maritime SAC's designated boundaries using rapid field assessment techniques with the minimal environmental impact.

  • Cette carte des peuplements benthiques subtidaux du secteur Trégor-Goëlo est le résultat du traitement, de l'analyse et de l'agrégation des données des campagnes REBENT 10 et 11 (2006), HALIOTREGOR (2008) et IFR-NEOMYSIS (2011). Deux sources croisées d'acquisition des données ont été employées : un système acoustique embarqué (sondeur multifaisceaux) et remorqué (sonar à balayage latéral), permettant de définir des premières classes de signatures acoustiques, correspondant à des unités morpho-sédimentaires, complétées par des campagnes de prélèvements à la benne (échantillons sédimentaires biologiques) et des profils vidéo.

  • SeaMap were contracted by SNH to review and analyse acoustic data collected from the sea around St Kilda and to interpret these data using ground truth records.
