The dataset covers HELCOM and OSPAR areas as well as the Mediterranean Sea. It does not include the Black Sea. The dataset was created by combining pulse-block-days (PBD) data from the ICES Registry (for HELCOM and OSPAR areas) and ACCOMBAS (for the Mediterranean Sea). The data available from the ICES register and the ACCOBAMS demonstrator pulse-block-days (PBD) indicator do not give exact locations of impulsive noise emitting activities being carried out (the data shows the number of activities per spatial grid cell of the grid they use). These data layers were overlaid with the EEA 10 km grid, which means that information in the grid is not actual pulse-block-days. For example, if cell of the EEA grid has a PBD value of 200, it does not mean that there were 200 PBDs in that 10*10 km area, but that 200 PBDs were recorded in a larger area (ICES or ACCOBAMS grid cell) over which this 10*10 km area was overlaid. The dataset is transformed to a logarithmic scale (log10). /9j/4AAQSkZJRgABAQEAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRofHh0a HBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL/2wBDAQkJCQwLDBgNDRgyIRwhMjIyMjIy MjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjL/wAARCADIASwDASIA AhEBAxEB/8QAHwAAAQUBAQEBAQEAAAAAAAAAAAECAwQFBgcICQoL/8QAtRAAAgEDAwIEAwUFBAQA AAF9AQIDAAQRBRIhMUEGE1FhByJxFDKBkaEII0KxwRVS0fAkM2JyggkKFhcYGRolJicoKSo0NTY3 ODk6Q0RFRkdISUpTVFVWV1hZWmNkZWZnaGlqc3R1dnd4eXqDhIWGh4iJipKTlJWWl5iZmqKjpKWm p6ipqrKztLW2t7i5usLDxMXGx8jJytLT1NXW19jZ2uHi4+Tl5ufo6erx8vP09fb3+Pn6/8QAHwEA AwEBAQEBAQEBAQAAAAAAAAECAwQFBgcICQoL/8QAtREAAgECBAQDBAcFBAQAAQJ3AAECAxEEBSEx BhJBUQdhcRMiMoEIFEKRobHBCSMzUvAVYnLRChYkNOEl8RcYGRomJygpKjU2Nzg5OkNERUZHSElK U1RVVldYWVpjZGVmZ2hpanN0dXZ3eHl6goOEhYaHiImKkpOUlZaXmJmaoqOkpaanqKmqsrO0tba3 uLm6wsPExcbHyMnK0tPU1dbX2Nna4uPk5ebn6Onq8vP09fb3+Pn6/9oADAMBAAIRAxEAPwD3+iii gAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKA CiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAK KKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAoo ooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiii gAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKA CiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAK KKKACiivPvhv4p1rxDaTvrFpcHz5ZZ7W5jhVbcQhggjDA53Bg/Dc4GcniqUW02ug7aXPQaKKKkQU UUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABWP L4k0iHXYNDa+iOpzlglumWYbU3ndjOz5eRuxntmtivlbXNZ1Kz+JmtanBPJ9osr+4EcjOxKAMyKe CMhV7HK4GCCMg7UaXtG0XCHNc+qaybbX9Lu2v0jvEzYEi7LgosWN2clgBj5W56cV4xpHhbxn44vL bXr+dI45DE63V6QGeHkHyolXAGOedobdkdSaw1WB2ltZblLjS5LhriJjEQZgoZY2IbO3q+BgHMhz nC4v2Cs9b27HNXqOk7y2/F+R9E6ZqUGradDfWu/yZRkb1wwIOCCPUEEenpmtCue8H2dzYeF7KC6G 2b55CuCCgd2ZVIIBBAYAjHUHr1rbeRI2RXdVZztQE4LHBOB6nAJ/A1zvcum24Jy3OT8ZltTu9K8L vLcQW2s+fHcy242yKkab+HzhckBSCrBlZhkd9nRrLSLOOaDSraKL7P5dpKyIdx8tFCKXPL7VIGcn HIzkGsXxxY+Fb5dPh8TQfaJGkkFnCszo7HbucgKy5ACjk8DIHfnlZjqWoTapqHhXxB/ZWn3Vwgnh uFVpGu5XSIEEI7IjArg54YHgDkXG0vdTt+RTqLmUL69j1WKeKWWZElR2ibY6qwJRsBsH0OGU49CD 3qxXOaD4abRZnuJNWur24lhSOeSWGBTKUACszLGHYgAgbnbgnqea6Oodug2FFFFIAooooAKKKKAC iiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAK47xD8N/DviEBntjY3 BkaR7ixVInlLfe3/ACkNk85Iznvyc9jRTjJxd0xp2POde1uw1XWLnwBb+GZdSihtw9zDHdJbIiKI 2jC4YHG5kB+6QBwGHFeZyXEj+K7972Ga3El7cNPCkis0bM+WG4dcYxkdlGO1ehLZ6m3xSurrRfEd pHFqaWd9JarEZPtFnGAjMJChUc5ACtk785GBnE+IngyLTNcj1xJryDRriV5NRe3UPJC5P8JZuA5Y 8nhT6gha66fJbkfVfiZ4mkqkOW51Hhbxqt/Hpej6dpz3DxQqs7tOqCOJSqeYAcluCCRwR0561yOo eE/Hmj6hF4wv72DW723lj820tVcu8SumFjAjwMncWAUYwW5JOO0msbLStKj8O+HoJb29soSsn2e7 CXUCu6yMWkIITzDhtpK7gPlBC/L1V3pMV/4fn0e4mneGe1a1kl3DzCrJtLZxjdg5zjr2rHnUXotP MKScLwlqvNHC+L9cT+0vDmpm2hxBHLLJZ3tmGnjkeJWiwWX5Cr7d21wenXHE3gXTtKMVk10JDq0B lvLdXjkj8uOQLGSP4XDADnnrx0zWrpfgew0iOOKzSKGKK8WdJPKWWV0Cj5Czg7Pn/uAYA4wxLV0l rDcw+f8AaLv7RvmZ4/3YXYh6Jx1x69TU81o2Rjy1JVVUb0Wi/q5eooorM6QooooAKKKKACiiigAo oooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACvnvx/4/fxFqUdjpl4Y 9EITeJgqiR1Zj5mB8xTGwgHHIyQDXvk8EVzbyQTxJLDKpR43UMrqRggg8EEdqwL7whpcWmXp0PSd NsNUe3ljtbqG3WJopGQqGDou5evUc1rRnGDu1cat1PPfBnijUdC8H3Q0vRpdZs7GSWW4uTeLCkXG 9lRSnQDBIXccsT3qc+I1+JF82kxTy2tx/Z32m3tY1WaFLjblWkmUFhjftKlQBxzuO2uv8AW/iOx0 6ew1yzEEcLboZWlWSSZnZ3kLkM2Tkj06966Ww0yw0uFodPsrezhZt7JBEsalsAZIAHOAOfYVc5pS btqZqClG09f19SnpOgWuj3mp3cUk01xqNybieachn6ALGCADsUcKpzjJraoorBu5d77hRRRSAKKK KACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAoooo AKKKKACiiqUV/ayX01ikoNxEoZ4yCCAehGeo+nSgTaW5dooooGctb+L4/wDhJp9E1C0aym37baVp Ayz+nOBgkYIHPXHXg9TXIeKvCMevYeGG2W48tx5jkqS52BSSo5ACkc57VgaTP4n0HxLaaZqeoC5t 5XDP5kpk3h/lBDFSww2OOBkdgc004yT6W/H0/rc5HXlSlaotG9H/AJnp1FFQyxJMoR0VlDBsMMjI OQfqCAfwpHWTUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQA UUUUAFFFFABRRWTe6V9quvtUU7QzbBHuVcnAJI9PU/nWVac4RvCPM+17CL9wrvbyJE212QhWzjBx wayPDukSabpkK33kzaiAwmuVyzOC5YZYgMe3X0rbVNiBRngY5OT+Zp9Wlrf+v61E4ptSYUUVkeIJ zbaLdSLIY22hN4JBG4hcg9jzwexolJRTbCUuWLl2Haxq8Giaa17dJM8SsFIiTceTj6Ae5I/MgVla Hb2WtJJqk9zHqkcqiNRPbIGhAJO1gOM/MM8DOAemK4tdd1yPNpPcefpN0ZIJJJcM8SndnBJDEkDC kkjnp0rrPAk+m/Yruz01L1RDIskn2nZkswx8u09Pk70RqQnovX+vPyOCFZVqsb2t263/AF+Z2VFF FUeiFFFcXqnjaMQxrojwzzE7maeNgmznIHIO7OPbmk2krsyq1oUlebOki1Sxnvms4buGW4UMzxxu GKbSAd2OhyQMH+hrQry3wdpkbaxaajJdmS93y+esj85KNntljznr059K9SqIVYVL8nR2+ZOHqSqQ 5pK3+QUUUVobhRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFA BRRRQAVla9p8mqaPPZxSKkj7SrMMjKsGAPscY/GtWigmUVKLi+pwVt4HurqYvq15GIxuVIbQMMAr wwY4wwYk9D0H0re8P+FbPw2101pPczNc7fMa4cMflzjGAP7xrbeNZEKOoZWGCCMgiorS3S0gWCMt sTO3cc4GeB9B0HsKmC5FyRVkY08NTpu8Vr36lmiiiqOgK57/AIQzw+0RjOnrtLBv9a+cjPfOR16f T0FdDRQROlCfxpP1Mm30LS7W7W7gso47hY/KDrkHb/U+/X3rWoooHGEYq0VYKKKKCgooooAKKKKA CiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAK KKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAoo ooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKAP//Z
