20170214 10293500 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 American Shad 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 American Shad were caught received the value of 0.1 (NUMi=0.1). All other data points where American Shad were caught kept their value as the number of American Shad 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 American Shad Presence" and "Fall American Shad Presence" Displayed interpolated categories were created by giving "Not Surveyed" (NUMi=0, 311 data points) and "Absent" American Shad (NUMi=0.1, no American Shad presence), their own category. Then, remaining data points were binned into the following categories based on the aggregation behavior of the species: Absent=0 American Shad Low=1-25 American Shad Medium=26-100 American Shad High=101-500 American Shad American Shad Fisheries New England North Atlantic Trawl Resource Survey Coastal Fish Climate Change Displays the estimated presence/absence of America Shad according to data collected by the MA Division of Marine Fisheries Resource Survey from 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+smWJo9SmkLlkkAKg/wEcHH1qxFdeXlWOVHv0rkhivea mrakxkmm5aa2L1FICGAIOQaWusoKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAK KKKACiikY7RnBP0oegEFxbCUDHXOapT2caWyiRi7FcOSOTxzx+HQVZe8IGQAAPWq+4u2SQQK86u6 Ur2V2zKtTUpKNtWTW0uzC/wH9KvVmVctpdy7T1H61rhqn2GdLpuMUT0UUV2GYUUUUAFFFFABRRRQ AUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAVlXupNDfJarG2HIG7HHIPf8K1azX+Ylz15PSuTFuXKl B2/yIqRm43g7WIZo0njZJV3KwwRmnooRQo4A4ApNwyBkAnoKfXFZXv1FhY803Ue4UqsUYMOopKKa dj0DRRw6Bh3p1UreXy3wfumrtelSqc8b9TmnHlYUUUVqQFFFFABRRRQAUUUUAFFFFABRRRQAUUUU AFFFFABRRRQAU3Yuc4GadRSaTAq3VrFIVmKjzI87T9etVq0+tZsuxZnRGBK9RnpXHiaai+ZdRRlG lJy7iUUzL5PTk8cdOO9AO5yg4OAckcc//qrlB4y6VlqPq5bS712nqP5VWMLKduVY+gpqOUcMOorW nJ05XZvzqorPRmlRSKwZQw6Glr0jEKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAoooo AD0rOkt2SV2Ef3juZwOv1rRoPTmsqtJVFr0JlFSVmc8l5HdSPDG/zKu4FDz1I6H/ADzVrOeRjOcV mRQzNqNw4mVoVk/hXaRznB9QP1FWJUMEiPFtLy5DDHDtjg+3Q/nXgUq0+VymutvxtoeVCcrXki+p Pmq2elT3KAOHXo3X61VRQowAB3OPU9asr81q+TyDkV6MNYuL9T06D9zmvsS2rZQr6VYqlZuGkYD3 HTvV2u3Dy5qaNptN3QUUUVsSFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRUckwjIB5z70n JRV2DdhzvsXNJHIJM46CqU05dtuDjrVq1H7rPrWEavPUsthQnGSduhS1DRo7y3njhnltnm5aSM85 xiobbSGtJSI5GMRUKIz0GO+a1pJVjxuPWoPtfov61hVw2G51JqzM/q9Jy5mtRVs1BBZifYU6UCOL ai8Hgmqs1+YkLswVfXHShbhpEb59w6cGn7WkrxjuaxlCTcU/OwWkapcllGC5y3vxj+laNUrYZmHs M1drXCq0PmPl5EohRRRXSIKKKKACiiigAooooAKKKKACiiigAooooAKKKKAK8lyqTFME4HOPX0qp cTO/zBN2Ow64qW7XbIWPQjNY9nrIuA37pVYFuN2TgDI4715OJxKhP2c5WvexyYmooSUZPfY0YyJA 5zhVbbn1PtU/mSCMBMhR7UkKNLL84bAAOWHWrTPCV2eYgyMD5hW9KDcb3sa0YxSvIoMzNjcc44FN ZguM9zipLhRDGzjL4BOFGSao39tJeWojjcRncGyRXLWlKCdldroc9dShe2rJ5YlmUKxYAMG4OOlT A/LiqVtFKr+Zvba+SyuPmBwAP5H86tqQwDDOD61NOXN71rNmmEl7/NYt2g+Zj7VaqC0H7sn3qevW oK1NHbU+IKKKK1ICiiigAooooAKKKKACiiigAooooAKKKKACiiigCOWISrjoR0Nc5eaT5UiPZwhJ PMG/5yOPzrp6jliWUc8H1rixmChiI6rUirRp1o8tRfPqikWYoE3ZArPi05YbrzVb5epGOST1JNar Wrj7pBqPyZP7hrlq4dyac1sazw9Kpbm6EeKUcdRkU7ypP7jflR5cn9xvyquWXYuVGD2Y6JLd0GJM HHSnyrEsQ2MCc+tQrAyqFWIgDoAtTRWzMcuML/OtIczXLy6k04OGsrfIsQLthX35qSjpRXoRVkkS 3d3CiiimIKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKK KACiiigAooooAKKKKAP/2Q==
