The mortality and serious injury of short-finned pilot whales in the U.S. pelagic longline fishery has recently exceeded Potential Biological Removal levels, and the bycatch mitigation techniques developed to date have been unsuccessful. The objectives of this thesis were to describe the spatial and temporal characteristics of pilot whale and longline data, to examine spatiotemporal patterns of bycatch based on environmental factors, and to assess the potential for a spatial management approach for mitigating pilot whale-longline interactions. I used pilot whale telemetry, longline fishing effort and government-observed data in combination with Area Under the Curve and Williamson\u2019s Spatial Overlap Index analyses to assess patterns of overlap and interactions between pilot whales and longlines. I determined that the most important environmental drivers of interactions were proximity to the shelf break, bathymetry, season, and sea surface temperature. Shelf break proximity and bathymetry effectively identified regions of high pilot whale-longline overlap and observed interactions, which predominantly occurred in fall and winter months. Interactions were primarily observed in the coldest sea surface temperature portions of both the pilot whale and longline distributions. My results suggest that static management alone, based on shelf break distance and bathymetry, effectively identifies regions with high interaction rates; however, it is necessary to incorporate seasonality and sea surface temperature to inform effective dynamic management plans to reduce pilot whale bycatch in the pelagic longline fishery."},{"label":"dcterms.available","value":"2018-07-09T14:32:10Z"},{"label":"dcterms.contributor","value":"Read, Andrew J."},{"label":"dcterms.creator","value":"Stepanuk, Julia Eve"},{"label":"dcterms.dateAccepted","value":"2018-07-09T14:32:10Z"},{"label":"dcterms.dateSubmitted","value":"2018-07-09T14:32:10Z"},{"label":"dcterms.description","value":"Department of Marine and Atmospheric Science."},{"label":"dcterms.extent","value":"62 pg."},{"label":"dcterms.format","value":"Monograph"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/78370"},{"label":"dcterms.issued","value":"2017-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Submitted by Jason Torre (fjason.torre@stonybrook.edu) on 2018-07-09T14:32:10Z\nNo. of bitstreams: 1\nStepanuk_grad.sunysb_0771M_13460.pdf: 3020151 bytes, checksum: 8719a667c313e81c1e0bbe20be419056 (MD5)"},{"label":"dcterms.subject","value":"Marine biology"},{"label":"dcterms.title","value":"Spatiotemporal patterns of short-finned pilot whale and pelagic longline distribution in the Northwest Atlantic: An assessment to inform the management of fisheries bycatch"},{"label":"dcterms.type","value":"Thesis"},{"label":"dc.type","value":"Thesis"}],"description":"This manifest was generated dynamically","viewingDirection":"left-to-right","sequences":[{"@type":"sc:Sequence","canvases":[{"@id":"https://repo.library.stonybrook.edu/cantaloupe/iiif/2/canvas/page-1.json","@type":"sc:Canvas","label":"Page 1","height":1650,"width":1275,"images":[{"@type":"oa:Annotation","motivation":"sc:painting","resource":{"@id":"https://repo.library.stonybrook.edu/cantaloupe/iiif/2/13%2F87%2F55%2F13875571233125954449373426801255559505/full/full/0/default.jpg","@type":"dctypes:Image","format":"image/jpeg","height":1650,"width":1275,"service":{"@context":"http://iiif.io/api/image/2/context.json","@id":"https://repo.library.stonybrook.edu/cantaloupe/iiif/2/13%2F87%2F55%2F13875571233125954449373426801255559505","profile":"http://iiif.io/api/image/2/level2.json"}},"on":"https://repo.library.stonybrook.edu/cantaloupe/iiif/2/canvas/page-1.json"}]}]}]}
