The Ministry of the Environment requested in 2011 the Consortium GEUS and Orbicon to carry out mapping tasks in the Danish part of the Kattegat and Western Baltic, partly as part of the government's raw material mapping and partly in connection with the implementation of the Marine Strategy Directive. This studyarea covers part of Kattegat
Areas of high riverine inputs for EUSeaMap 2019 Biological zone model. The map cover the Adriatic Sea (Po river plume), east Mediterranean (Thessaloniki gulf and bay, the Maliakos gulf, and Geras gulf in the Aegean Sea) and the Black Sea (Dnieper-Bug river plume area). These were handled separately in the modelling process. This layer is one of several habitat descriptors used to model biological zone and habitat class. To establish the limit of these areas datasets on salinity and water temperature were used, where possible. Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.
JNCC and Centre for Environment, Fisheries and Aquaculture Science (Cefas) undertook aseabed survey (CEND 22/13 & 23/13) at the North Norfolk Sandbanks and Saturn Reef SCIbetween 4 November and 25 November 2013 on the RV Cefas Endeavour(Vanstaen and Whomersley 2014). The aim was to gather additional seabed data to assist with the development of management advice for the site. Locations of known S. spinulosa reef, along with historic records where reef had been previously observed, were surveyed to assess presence, and where possible, delineate the Annex I biogenic reef feature and characterise associated fauna.
DATRAS Web Services offer a possibility to search and retrieve data from DATRAS database by granting direct access to the data. DATRAS (getCAdata) service returns age-based information such as sex, maturity, and age counts per length of sampled species for the given survey, year, and quarter.
Seabed habitat map (EUNIS habitat classification system) performed by GIS Posidonie within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources : Side scan sonar (2010), digital elevation model (2010), orthophotos 2008, satellite images (2010), historic habitat maps (1965). Ground truth data sources (2010) : Divers with underwater cameras (37 points), ROV (9). Map confidence rated by Ifremer : 89% (Areas with doubtful outlines are mentioned in the "VAL_COMM" field).
Carbonate sand deposits are modelled for the Trondelag coast of Norway (Bekkby et al. 2013). The model was carried out in the projection UTM zone 33N. Carbonate sand deposits were defined as having at least 50 % carbonate content. The model was developed based on 1105 data points and GAM analyses of presence and absence points. Data were collected 2007-2008 by the Geological Survey of Norway (NGU), the model was run in 2009 by NIVA. The distribution model is based on depth, wave exposure and maximum current speed, depth being the most important variable (see Bekkby et al. 2009 for explanation of the GIS environmental layers). The input depth and wave exposure models had a spatial (horizontal) distribution of 25 m, the current speed model was resampled from 500 m resolution. The output model has a spatial (horizontal) distribution of 25 m. The work was part of the National program for mapping biodiversity – coast, a program that is funded by the Ministry of Climate and Environment and the Ministry of Trade, Industry and Fisheries. The Norwegian Environment Agency is leading the project and NIVA is the scientific coordinator.
The objective of the study is to provide more information about the seabed for use in substrate and habitat classification. In the classification there have been used 2134 km of data with sonar, sediment echosounder and sidescan. Furthermore 4519 km seismic and acustic archive data from existing studies have been included in the analysis. The study area consist of Kattegat and the Belt Sea. This area lies in the south west Baltic Sea.
Seabed habitat map (EUNIS classification system) performed by Stareso within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources: sonar (2010-2011), orthos (2010-2011), historical data (Guennoc et al., 2000; Pasqualini, 1997) Ground truth data sources (2008-2012): diving, sea-viewer Map confidence rated by Ifremer : 89%
Seabed habitat map (Habitat Directive) performed by IN VIVO within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Map confidence rated by Ifremer : 57%
The substrate and nature type mapping was carried out for the Danish Nature Agency in the summer 2012. The survey included habitat classification of Limfjorden, Kattegat and The Belt Sea This studyarea is a part of The Belt Sea.
