EMODnet Physics - TSM_NorthSea - Concentration of total suspended matter (conc_tsm, mg/l) is a product of the Coastcolour L2W Concentrations Data, obtained from the OC4 algorithm for clear and moderate turbid waters, and from the CoastColour v1 neural network.The L2W product was then remapped on a regular grid, maintaining the 300 m full resolution, in order to obtain L3 products over the North Sea and monthly averaged. Developed by EMODnet Physics.

Saccorhiza polyschides distribution in the Portuguese mainland from historical data. Data provided by the Project FindKelp and published in: “Findkelp, a GIS-based Community Participation Project to Assess Portuguese Kelp Conservation Status”. Journal of Coastal Research (2009) :SI 56 (1469-1473)

The data were acquired with Reson SeaBat 7150 and 8111 multibeam echosounder systems on board the R/V OGS Explora in order to cover the Malta Escarpment for a geological survey in the framework of EU FP7 project SCARP.

Zostera noltii meadows distribution in the Portuguese mainland from historical data. Data provided by the Life Project BIOMARES and published in: “Seagrasses in Portugal: A most endangered marine habitat”. Aquatic Botany. doi:10.1016/j.aquabot.2011.08.007. “Estimation of available seagrass meadows area in Portugal for transplanting purposes ”. Journal of Coastal Research (2009) :SI 56 (1100-1104)

The DTM is produced with Kongsberg multibeam echosounder survey, acquired in 2015 by Marine Research Ltd. The resolution is 1/256 arc-minutes (~7.2m). It is located south of Constanta Port, Romania, on the coastal region of the Black Sea. Depths are referenced to the Mean Sea Level and the coordinates are expressed into the WGS84 reference frame.
