In general, trawlers operated in the north-western and eastern territories of Lefkada island, east of Kefalonia and Zakynthos islands, inside Patraikos Gulf and in the northern part of Korinthiakos Gulf. The highest values of fishing effort were identified around the Astakos region, the outer part of Patraikos Gulf and the western part of Korinthiakos Gulf. The Trawler Fishing Effort (TFE) criterion was based on the intensity of trawler fishing effort. Ranking was based on four defined classes, under the assumption that coastal fishing pressure should be low when TFE is high. https://www.portodimare.eu WWW:LINK-1.0-http--link Online link to the 'Bottom trawl fishing effort around Kephalonia island' description on GeoNode https://www.portodimare.eu/download/2494 WWW:DOWNLOAD-1.0-http--download .zip Bottom trawl fishing effort around Kephalonia island (Original Dataset Format) https://www.portodimare.eu/geoserver/ows?layers=geonode%3Abottom_otter_trawl_effort&service=WMS&format=image%2Fjpeg&request=GetMap&height=550&width=677&bbox=20.2669892389832%2C37.9079004359109%2C21.5049808854221%2C38.9125002145786&srs=EPSG%3A4326 WWW:DOWNLOAD-1.0-http--download .jpg Bottom trawl fishing effort around Kephalonia island (JPEG Format) https://www.portodimare.eu/geoserver/ows?layers=geonode%3Abottom_otter_trawl_effort&service=WMS&format=application%2Fpdf&request=GetMap&height=550&width=677&bbox=20.2669892389832%2C37.9079004359109%2C21.5049808854221%2C38.9125002145786&srs=EPSG%3A4326 WWW:DOWNLOAD-1.0-http--download .pdf Bottom trawl fishing effort around Kephalonia island (PDF Format) https://www.portodimare.eu/geoserver/ows?layers=geonode%3Abottom_otter_trawl_effort&service=WMS&format=image%2Fpng&request=GetMap&height=550&width=677&bbox=20.2669892389832%2C37.9079004359109%2C21.5049808854221%2C38.9125002145786&srs=EPSG%3A4326 WWW:DOWNLOAD-1.0-http--download .png Bottom trawl fishing effort around Kephalonia island (PNG Format) https://www.portodimare.eu/geoserver/wcs?service=WCS&format=application%2Fx-gzip&request=GetCoverage&srs=EPSG%3A4326&version=2.0.1&bbox=20.2669892389832%2C37.9079004359109%2C21.5049808854221%2C38.9125002145786&coverageid=geonode%3Abottom_otter_trawl_effort WWW:DOWNLOAD-1.0-http--download .x-gzip Bottom trawl fishing effort around Kephalonia island (GZIP Format) https://www.portodimare.eu/geoserver/wcs?service=WCS&format=image%2Ftiff&request=GetCoverage&srs=EPSG%3A4326&version=2.0.1&bbox=20.2669892389832%2C37.9079004359109%2C21.5049808854221%2C38.9125002145786&coverageid=geonode%3Abottom_otter_trawl_effort WWW:DOWNLOAD-1.0-http--download .geotiff Bottom trawl fishing effort around Kephalonia island (GeoTIFF Format) https://www.portodimare.eu/geoserver/ows?service=WMS&request=GetLegendGraphic&format=image/png&WIDTH=20&HEIGHT=20&LAYER=geonode:bottom_otter_trawl_effort&STYLE=bottom_otter_trawl_effort&legend_options=fontAntiAliasing:true;fontSize:12;forceLabels:on WWW:DOWNLOAD-1.0-http--download .png Bottom trawl fishing effort around Kephalonia island (Legend Format) https://www.portodimare.eu/geoserver/ows?layers=geonode:bottom_otter_trawl_effort&crs=EPSG:4326&service=WMS&format=image/png8&request=GetMap&height=180&width=240&version=1.1.1&bbox=20.266989238983200,37.907900435910900,21.504980885422100,38.912500214578600 WWW:DOWNLOAD-1.0-http--download .png Bottom trawl fishing effort around Kephalonia island (Remote Thumbnail Format) https://www.portodimare.eu/uploaded/thumbs/layer-bf55a4d0-15ce-11ea-ae7e-0a580a81020b-thumb.png WWW:DOWNLOAD-1.0-http--download .png Bottom trawl fishing effort around Kephalonia island (Thumbnail Format) https://www.portodimare.eu/geoserver/ows OGC:WMS geonode:bottom_otter_trawl_effort Service - Provides Layer: Bottom trawl fishing effort around Kephalonia island https://www.portodimare.eu/geoserver/ows OGC:WCS geonode:bottom_otter_trawl_effort Service - Provides Layer: Bottom trawl fishing effort around Kephalonia island dataset
