20170217 09440800 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 gAooooAKKKKACiiigAooooAjM0Yk2FwG9KkrJnYJqD5I5Gf8/kanguwrGPcGx1GeRUTk4S1Wltwh 7yfe5fopAQwBByDS1YBRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUj HaM4z9KHoBmatZzSoJLNYxcDPzycDHoeM1VtbaVdGtJbqRWu2iVpSilRuIycA9BWhNeOq5UYwaqo RIQAMIo4FP6w/ZXjsnv+hnKlF1LPd/1ctWsxXaG+6f0q9WZVy2l3LtPUfrXHQq3fKzqnCyuT0UUV 1mIUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAVnXV6wkdIyMKdp479a0a5241j T0G9pgfMcjCoSc4PJwOBx1prmvZRcvQmdrfFYe8jSHJqeBcJn1qsg34x3q90FRj5KEFSiRg4uc3U kFKrFGDDqKSivKTseiaKOHQMO9Oqlby+W+D901dr0qVTnjfqc048rCiiitSAooooAKKKKACiiigA ooooAKKKKACiiigAooooAKKKKACq4sbbzTIYULk5yVHFWKKabWwmk9ytcwIR5oGHXv61VrT61lXb CGQon/6q561GVWS5S41I002x1FVfOk/vfpTklkdgu4DPc1LwFRK7a/r5CWNpt2syxVy2l3rtPUfy qmYZo2xuWTuQp5pIZTncBgg9DWahKi+bdGnPGfu7M1KKRWDKGHQ0tdpkFFFFABRRRQAUUUUAFFFF ABRRRQAUUUUAFFFFABRRRQAUUUUAI4LIyhipIwGHb3rLuLaULucghBlnPGfetWmuFKMG+6Qc/ShX TTXQUkmmmc8jrIgdGDKehFOqrp0Pk2agNuVjuXjoDyKtV6Ukk2keWnoTRSv56EknBFXblAk29cbX 9PWs6MhZAT0q9Ix+wSOoLsh3KB3/AM8152Iiuf2aW6O/DyfI5t7Ms2rZQr6VYqlZuGfjoRV2saN+ Sz3R0Tte6CiiitSQooooAKKKKACiiigAooooAKKKKACiiigAooooAKKMjOO9YWr+IP7O1K1tILdr uaU7XjRseWCV+ZuDgDP6jr20p0pVJcsVqROpGC5pGtc3H2dAQu9icBd2KkjkEmcdBWE089w++cbd pJjU4JTPUZHBrYs8G3DDvSq05QcUKnUU7jLixSY7lO0/TrVZbB1fnDCtCWZIQC7AZqA36f7P51m5 tR5U3Yrkg5cz3FjsY07n8KdOoSAoi8EEE1UbUWydopVuWkiYsT6YrOcZQXPyv1/rUqMoS91MLHG9 MH1rSqhZpiRR/dFX6KUubmkurY2uVJeQUUUVqIKKKKACiiigAooooAKKKKACiiigAooooAKKKKAK d3c+Q28KzFAcKCBuOOmfyrl4Fur3WTqFzGUKRGFCwwxXduAPr9f/AK9dJfRks3uMiqKMVIwoJ9xm ujB1bRkuu3yOXFRd12FSIsNzHavQH1PoKt5mSILE21B7dTTba3kknBlDYUZ+atBjHs2llAIwOayr TnKXuPRF0YRUbyRiyPI7YdiSvFMq3c26xpuUg89aqV0UainG66HNVpuErMKtQPmLb6GqtTom10Iz tYVljUpU7P1+41wraqXRoWg+Zj7VaqC0H7sn3qeuSgrU0d1T4gooorUgKKKKACiiigAooooAKKKK ACiiigAooooAKKKKAI5YhKuOhHQ1nyR87WBBFalRyxLKOeD61hVpNvmjuXGStyy2M6V5GVYc5GPv VGLdfU1da0YcqQaj8mT+4aydWtBcsdB+ypyd5alfy2ClQ3B9aaoaAncu5SO3arPlSf3G/Kjy5P7j flSjiKlmpK6e4OhC6cXZoSKK0kGfMAbuDU0qwiIbGBIPY1B9nJOfKOf92p4rZifmG1fSqnP2itFP 5hCPJq7fIsQLthX35qSjpRXVFWSRDd3cKKKKYgooooAKKKKACiiigAooooAKKKKACiiigAooooAK KKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooA//9k=
