20170214 12553300 1.0 North American Profile of ISO19115 2003 TRUE Data was provided by the Massachusetts Division of Marine Fisheries (DMF). Data was collected during the bi-annual (Spring and Fall) Resource Survey from 1978-2016. DMF provided the following information for every trawl: latitude, longitude, cruise number, stratum, trawling station, set dept, date of trawl, bottom temperature, number of each specie collected in net, weight of each specie. Latitude, longitude, and number of each specie collected in net data was used to create this visual. Separate data sets were made for spring data (green) and fall data (blue). Each dataset identifies the number of Silverside caught during each trawl (3781 data points in the Spring, 3450 data points in the Fall) and the location of each trawl. To effectively interpolate using Natural Neighbor and to show areas that were “Not Surveyed”, shapefile points were created along the Massachusetts border, around the Martha’s Vineyard and Nantucket border, and outside the extent of the DMF trawl. Not surveyed data points (n=311) were assigned the value, NUMi, of 0. Trawl data points where no Silverside were caught received the value of 0.1 (NUMi=0.1). All other data points where Silverside were caught kept their value as the number of Silverside caught. Natural Neighbor Interpolation Tool was then used for all these data points according to "NUMi" category. The interpolated data can be found in "Spring Silverside" and "Fall Silverside" Displayed interpolated categories were created by giving "Not Surveyed" (NUMi=0, 311 data points) and "Absent" Silverside (NUMi=0.1, no Silverside presence), their own category. Then, remaining data points were binned into the following categories based on the aggregation behavior of the species: Absent=0 Silverside Low=1-25 Silverside Medium=26-100 Silverside High=101-500 Silverside Very High=501-568 Silverside Silverside Fisheries New England North Atlantic Trawl Resource Survey Coastal Fish Climate Change The estimated presence/absence of Silverside according to data collected by the MA Division of Marine Fisheries Resource Survey, 1978-2016 Amanda Davis and Dr. Michelle Staudinger of the Northeast Climate Science Center (NE CSC) and Brad Chase of Massachusetts Division of Marine Fisheries (MA DMF) /9j/4AAQSkZJRgABAQEAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRofHh0a HBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL/2wBDAQkJCQwLDBgNDRgyIRwhMjIyMjIy MjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjL/wAARCACFAMgDASIA AhEBAxEB/8QAHwAAAQUBAQEBAQEAAAAAAAAAAAECAwQFBgcICQoL/8QAtRAAAgEDAwIEAwUFBAQA AAF9AQIDAAQRBRIhMUEGE1FhByJxFDKBkaEII0KxwRVS0fAkM2JyggkKFhcYGRolJicoKSo0NTY3 ODk6Q0RFRkdISUpTVFVWV1hZWmNkZWZnaGlqc3R1dnd4eXqDhIWGh4iJipKTlJWWl5iZmqKjpKWm p6ipqrKztLW2t7i5usLDxMXGx8jJytLT1NXW19jZ2uHi4+Tl5ufo6erx8vP09fb3+Pn6/8QAHwEA AwEBAQEBAQEBAQAAAAAAAAECAwQFBgcICQoL/8QAtREAAgECBAQDBAcFBAQAAQJ3AAECAxEEBSEx BhJBUQdhcRMiMoEIFEKRobHBCSMzUvAVYnLRChYkNOEl8RcYGRomJygpKjU2Nzg5OkNERUZHSElK U1RVVldYWVpjZGVmZ2hpanN0dXZ3eHl6goOEhYaHiImKkpOUlZaXmJmaoqOkpaanqKmqsrO0tba3 uLm6wsPExcbHyMnK0tPU1dbX2Nna4uPk5ebn6Onq8vP09fb3+Pn6/9oADAMBAAIRAxEAPwD3+iii gAooooAKKKKACiiigAooooAYZUVtpYA0+qFwMTk+tOiuCnDcr/KuZYi0nGQ4rmXmXaKQEMAQcg0t dIgooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKRjtGcE/Sh6AQzQeZy vBqvLCI0Ug8nrT3u2AyAAPeqkNzHdxiWNtycgHGK8+rUpXst2TOMXJRfxMtW8pRgpPyn9Ku1mVct pdy7T1H61ph6v2GdFSGlyeiiiuwxCiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKA CqlxMwYopwOlW6znO4sx9zXPiJtRsh8rknZ2Iyc0RosaBUUKo6ADApEYOqsM4IzyMU+uDR6meFjz ydRhSqxRgw6ikooTsd5oo4dAw706qVvL5b4P3TV2vSpVOeN+pzTjysKKKK1ICiiigAooooAKKKKA CiiigAooooAKKKKACiiigAooooAKbsXOcDNOopNJgQXESspccMP1qirq4JRg2Dg4OcGtWsr7LDZv IkC7VZi5Hua4sVBqSktuo41PZ+g6ikzSFgBkkAep7VzFLFwY6rltLvXaeo/lVdoWVtuVY+gNMRyj hh1Fa05OnK7Lcoz06mlRSKwZQw6Glr0jEKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigA ooooAD0rPmilDEhQ3OSfatCkbG056Y5rKrTU1qxSV1ZmXTXRZEKOoZWGCD3qGzjdIMtK0pdi4LcY B7U+KdJnlVc5jba2fWvKjNSiubS/Q8/mTSv1Jd0vnRFCuA3zZ9MdvxxU9yMSqVUlWzlhjAIquVDE ZJGDng4qyo3Wr+oOa2grpx+Z2UW+VyvsyW1bKFfSrFUrNsv3wR3q7Xdh5Xpo3nZu6CiiitiQoooo AKKKKACiiigAooooAKKKKACiiigAooooAKKKjkmEZAPOfek5KKuwbsOd9i5pscnmMSD8oHpVCW7M tw8O1gEAbPbnPH6VdtR+6z61zwre0naOxMJxmnboQT6bHLI7q7ozlScNxx/Km/ZXDEdcn8quSSrH jcetQfa/Rf1qJ0qEX2YlShfmsOW0UfeYn6UsoEcW1F4PBNV5L0orOzKijkk9qTzndDlsg1PtaSTj FalxlGT5Uxbb/XL+P8qv1SthmYewzV2tsN8A2uVJPsFFFFdAgooooAKKKKACiiigAooooAKKKKAC iiigAooooAhknCSbSDwKqSymVsntUlypEpPqKhDbewz7159WcnJxexFfSKS6gqZG4nC+vrUvmSCM BMhR7URRPJIN+cDnmrbbCm3cAMY61VOm2rp2JpQSV5GczM2NxzjgUlSyxBOjA81FWEk09TGpBxep BKElnSGSAugG8MRlQemPrzVkH5dvYU2nYxj3qFGzb7lYVNVLlm0HzMfarVQWg/dk+9T16dBWpo7K nxBRRRWpAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUARyxCVcdCOhqiylSQwwRWlUcsSyjng+ tc9ajz6rcuMlbllsUmdioUtkCmYqw1q4+6Qaj8mT+4a5JQmnqi+SnLV6keKUcdeRTvKk/uN+VHly f3G/Kp5ZdgdGF7p6jlihkTBkKkjntT5ViWIbGBOfWovKf+435VLFbMzZcYX+daxTeiiTGHK7u3yL EC7YV9+ako6UV3xVkkQ3d3CiiimIKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooA KKKKACiiigAooooAKKKKACiiigAooooAKKKKAP/Z
