Palka, D2013https://doi.org/10.82144/f095db80OBIS-SEAMAP288http://seamap.env.duke.edu/dataset/288OBIS-SEAMAPVersion 1.0.0 The ship survey was performed from 22 July 1991 to 30 August 1991 to estimate the abundance and spatial distribution of harbor porpoises. The study area, covering approximately 13,300 nm , was from Port Clyde, ME to 2 St. John, New Brunswick over to the Nova Scotian coast, up to Liverpool, Nova Scotia.PRIMARY OBJECTIVES 1) Estimate the abundance of harbor porpoises in the Gulf of Maine - Bay of Fundy - Nova Scotia area. 2) Investigate if there are any spatial distribution patterns of the harbor porpoises, and if those patterns are correlated with water depth or harbor porpoise group size. SECONDARY OBJECTIVES 1) Estimate the abundance and spatial distribution of other cetaceans. 2) Determine if harbor porpoise avoid this ship, and if so, at what distance. 3) Determine if there is a spatial distribution pattern of mother-calf pairs of harbor porpoise. 4) Compare the abundance estimate and spatial distribution of harbor porpoise as seen this year with that seen in previous years. 5) Investigate if inland bays can be surveyed using a rigidhull inflatable boat as the observation platform in a line transect survey. 6) Determine if Buckland's sighting procedure (1991), which is a line transect survey using both a primary and marking team, is a feasible procedure to estimate the abundance of harbor porpoise in the Bay of Fundy area.In addition to the sighting data, effort data was recorded every half hour or whenever conditions change. This dataset, therefore, should be used with the effort data.1991072419910827ground conditionCompleteNone plannedNorth Atlantic Ocean-69.017-64.55445.10442.811 NoneMarine Animal SurveyMarine BiologyMarine mammalsSea turtlesVesselVisual SightingNoneNorth Atlantic OceanTaxon coveredMarine mammals, seabirds, sea turtlesIntegrated Taxonomic Information SystemUnknownNot applicableDownloaded April, 2004http://www.itis.usda.gov/Refer to the contact information of the datasetRefer to the contact information of the datasetmailing and physical address
