20170214 10080000 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 Tomcod 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 Tomcod were caught received the value of 0.1 (NUMi=0.1). All other data points where Tomcod were caught kept their value as the number of Tomcod 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 Tomcod" and "Fall Tomcod". Displayed interpolated categories were created by giving "Not Surveyed" (NUMi=0, 311 data points) and "Absent" Tomcod (NUMi=0.1, no Tomcod presence), their own category. Then, remaining data points were binned into the following categories based on the aggregation behavior of the species: Absent=0 Tomcod Low=1-8 Tomcod Fisheries New England North Atlantic Trawl Resource Survey Coastal Fish Climate Change Shows the estimated presence/absence of Tomcod 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 gAooooAKKKKACiiigAooooAjM0Yk2FwG9KkrKuMR3rE9GHf/AD7VPDdbTtJ3D+VROfJLVadwh7yf cvUUgIYAg5BpasAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKRjtGc Z+lD0Ar3NqJhxw3rVC5tlgjjIb5j1FW5b1kXKqPxqkmZpCznOO1OlVUYOf2UZVqalJQ+0y5azFdo b7p/Sr1ZlXLaXcu09R+tcdCrd8rOucLK5PRRRXWYhRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRR QAUUUUAFFFFABWfeXUiSMi4Cjjp1rQrNk+fcTznJxUSqKDSavcORyTs7FJ5GkOTU8C4TPrVdQWYA d6u9BTx8lCCpRMsHFzm6kgpVYowYdRSUV5Sdj0TRRw6Bh3p1UreXy3wfumrtelSqc8b9TmnHlYUU UVqQFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAU3Yuc4GadRSaTArXMCEeaBh17+tVa 0+tZV2wikKJ/+qsa1GVWS5So1I002x1FVfOk/vfpTklkdgu4DPc1LwFRK7a/r5CWNpt2syxVy2l3 rtPUfyqmYZo2xuWTuQp5pIZTncBgg9DWahKi+bdGnPGfu7M1KKRWDKGHQ0tdpkFFFFABRRRQAUUU UAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAB6VmXNtKzE4zjJLetadB6c0tU1JboTSkuV7HPkEHB6 0lOkOZGPvTa9CLbimzzZKzdiaKV/PQkk4Iq7coEm3rja/p61nRkLICelaDfNZOwOSp3D/P51w4iK 5/ZpaNHbh5Pkc29mT2rZQr6VYqlZuGfjoRV2saN+Sz3R0Tte6CiiitSQooooAKKKKACiiigAoooo AKKKKACiiigAooooAKKKhnuFgKg8knGM0b6ITaSuyR32LmkjkEmcdBWXc3bynaOFBq/Z4NuGHeic Jxab2YoVIzukMuLFJjuU7T9OtVlsHV+cMK0JZkhALsBmoDfp/s/nSc2o8qbsHJBy5nuLHYxp3P4U 6dQkBRF4IIJqo2otk7RSrctJExYn0xWc4yguflfr/WpUZQl7qYWON6YPrWlVCzTEij+6Kv0Upc3N JdWxtcqS8gooorUQUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAV5blYpMNms67n8+QHsBgVZv oyWb3GRVFGKkYUE+4zVYbVuTeqMMS2ko9GKkRYbmO1egPqfQVbzMkQWJtqD26mm21vJJODKGwoz8 1X3eILtaRVzwOQKdac5S9x6IKMIqN5IxpHkdsOxJXimVbubdY03KQeetVK6KNRTjddDmq03CVmFW oHzFt9DVWp0Ta6EZ2sKyxqUqdn6/ca4VtVLo0LQfMx9qtVBaD92T71PXJQVqaO6p8QUUUVqQFFFF ABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFAEcsQlXHQjoaz5I+drAgitSo5YllHPB9awq0m3zR3LjJ W5ZbGdK8jKsOcjH3qj+yxn73NXWtGHKkGo/Jk/uGsnVrQXLHQfsqcneWpX8tgpUNwfWmqGgJ3LuU jt2qz5Un9xvyo8uT+435Uo4ipZqSunuDoQunF2aEiitJBnzAG7g1NKsIiGxgSD2NQfZyTnyjn/dq eK2Yn5htX0qpz9orRT+YQjyau3yLEC7YV9+ako6UV1RVkkQ3d3CiiimIKKKKACiiigAooooAKKKK ACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKAP/Z
