20170214 10044700 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 gAooooAKKKKACiiigAooooAYZUVtpYA0+ssriaVskhnJGe3b+lTxXBThuV/lXLDE3dpKwU/fjcu0 UgIYAg5Bpa6gCiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAoopGO0ZwT9 KHoBDNAHxt4P6VXmiEaIQ3J6ipGu2/hUD61XJLHJrgqypu/KRUheSj1ZNbylGCk/Kf0q7WZVy2l3 LtPUfrV4er9hnTUhpcnooorsMQooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAqp cTMGKKcDpVus5suxPc81z4iTUUl1GouSdnYjJzSjpSU6uAjCpyk5sKVWKMGHUUlFCdjuNFHDoGHe nVSt5fLfB+6au16VKpzxv1OaceVhRRRWpAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFA BTdi5zgZp1FJpMCC4iVlLjhh+tU606z51CSFV6Vx4mFveRcKkaabYyikzQOTiuUFi4PoxauW0u9d p6j+VVzCytjKsfQGmI5Rww6itacnTldluUZ6dTSopFYMoYdDS16RiFFFFABRRRQAUUUUAFFFFABR RRQAUUUUAFFFFABRRRQAUUUUAB6VQlhkBYkZHXNX6D05rOpTU1qDSaszKoqEXAa8e3Ebjau7eRwa mry4yUtjgum3yjkY+YpzyDU9ygDh16N1+tVx1qdfmtXyeQcitoapxOui3y8zezJbVsoV9KsVTtD+ 8I9RVyuyg7wRvO17oKKKK2ICiiigAooooAKKKKACiiigAooooAKKKKACiiigAooqKSZY2UHGT2zS lJRV2Ddtx7vsXNMguI7lS8Tq6dMqc1TupXmBQcA5Ge44/Wk0SyNjYBGfe5YkkdK5FXnKuoRXu2d2 ZKq5T5YrTqyd7FDM8qMQzgZGeOP5VH9lkDkdRnirkkqx43HrUH2v0X9adSnRT7FqnC97DltFH3mJ +lLKBHFtReDwTUBupDnGBTfOdlOWJqXUppNRRcZRlomLbf65fx/lV+qVsMzD2Gau1rhvgBrlST7B RRRXQIKKKKACiiigAooooAKKKKACiiigAooooAKKKKAIZJwkm0g8Cqk0nmsCQOOlSXKkSk+oqENt 7DPvXn1ZycnF7EYjSKS6jIUlw7TMoXcduPTsPrVjzJBGAmQo9qSKKSSUb87QMnNW2aLHl71BI4GR nFOlSfLo7fqRRhGK94z2ZmxuOccCkqSWERsWDZJ461HWLTT1MakHF6iAYAGc+5p4Py4ptOxjHvSN MNdTuizaD5mPtVqoLQfuyfep69GgrU0ddT4gooorUgKKKKACiiigAooooAKKKKACiiigAooooAKK KKAI5YhKuOhHQ1RZSpIYYIrSqOWJZRzwfWuetR59VuXGStyy2KTOxUKWyBUexdwbA3DjOOastauP ukGo/Jk/uGuSVOd9UXyU5avUjxSjjryKd5Un9xvyo8uT+435VPLLsDowvdPUekcLLzJhvQ06VYli GxgTn1qLyn/uN+VSxWzM2XGF/nWsbtcqiKMeV3dvkWIF2wr781JR0orvirJIzbu7hRRRTEFFFFAB RRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFF FFAH/9k=
