Spatial distribution for nutrients data (silicate, nitrate, nitrite, ammonium and phosphate) for all maritime regions in the English Channel and North Sea, the Celtic Seas and the Bay of Biscay. The temporal extent of the data is from 1930 to 2010, most being between 1974 and 2007 with a peak in 1999.

Acoustic water column data acquired in 2009 during the MARMESONET marine expedition led to establish an accurate spatial distribution of gas emissions on the scale of the Sea of Marmara. The present database is composed of a surface shape file (.shp) dedicated to GIS applications. This seafloor surface represents the insonified area within which gas emissions occurred for more than 1 month of survey, from 4 November 2009 to 14 December 2009; as displayed in Figure 4 of Dupré et al. 2015 (Dupré S, Scalabrin C, Grall C, Augustin AH, Henry P, Sengör AMC, Görür N, Çagatay N, Géli L (2015) Tectonic and sedimentary controls for widespread gas emissions in the Sea of Marmara. Results from systematic, shipborne multibeam echosounder water column imageries. Journal of Geophysical Research 120 (5):2891-2912. doi:10.1002/2014JB011617). This publication investigated and discussed the relationship between fluid emissions at the seafloor with the fault network (active and inactive faults) and the sedimentary environment (nature, thickness and related-processes).
