  • 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.

  • Region: The county Hordaland Number of field observations: 637 Field sampling year: 2004, 2005,2009, 2010 Prevalence: 34% Presence / absences: 215/422 Method: BRT run with the R-package Dismo. Number of predictor variables: 23 Information about the predictor variables: DEM (25 m resolution), slope, aspect, curvature at detailed, medium and coarse resolution (i.e. applying a 125, 525 and 1025 m moving calculating window respectively, based on the 25 m resolution DEM); wave exposure, latitude, longitude, and optimal radiation index, all with 25 m resolution; and maximum surface and seafloor current speed, slope of maximum surface and seafloor current speed, minimum surface and seafloor current speed, standard deviation of seafloor current speed, 10 and 90th percentile of surface and seafloor current speed, all current speed predictor variables with 200 m resolution, but resampled to 25 m. AUC independent data: 0.88

  • The description and mapping of marine habitat types according to Annex I of Directive 92/43/EOK (EEC, 1992) and / or the European Nature Information System (EUNIS) in 66 of approximately 300 Greek NATURA 2000 network sites, were the subject of Research Work for the Ministry of Environment Planning and Public Works of Greece. This research project, under the name "Identification and description of habitat types at sites of interest for conservation", lasted from 1999 to 2002 and was carried out by the National Centre for Marine Research (NCMR, renamed as Hellenic Centre for Marine Research - HCMR since 2003) in association with the Institute of Marine Biology of Crete (IBCM, joined to HCMR since 2003), the Aristotle University of Thessaloniki and the Fisheries Research Institute (FRI). The recognition and imprinting of marine habitat types was based on the combined use of aerial photos of scale 1:5000 acquired during the second half of 1999 for the needs of the project, data from the scientific echo sounder Sea-Bed discrimination system "RoxAnn", phytobenthos samples and in situ observations by scuba diving and underwater cameras. Regarding the sampling, hard bottom samplings were carried out using SCUBA diving. The samples were collected on hard substrates mainly in the upper infralittoral zone (30 to 50 cm below the lowest sea level). For the study of the soft bottom habitats, oceanographic cruses were carried out with the IMBC R/V “Filia”, using a Smith McIntyre sediment sampler.
