Methodology and datasets. This study is spatially limited to our definition of the European coastline that has been defined by the polygon shown in Figure 2. This polygon spans the Mediterranean Sea and includes the Northern African coast. We have also considered the coast of Greenland. The polygon intersects or includes 58 countries. The backbone of the GLOSS programme is the Core Network (GCN) composed of 290 stations evenly distributed worldwide, of which 38 stations belong to the study area (Figure 3, left). Although these are the key stations of the global network for scientific applications, GLOSS has different data portals whose applications result in them acquiring and distributing data from hundreds of stations around the world. For the purpose of this study, we have based our analysis in the following main GLOSS datasets:
