attribute NC_GLOBAL acquisition_description String Methods  \n I) Aerial Surveys\n \nAerial surveys were conducted from January through mid-May 2002 in the Cape\nCod Bay Critical Habitat and adjacent waters (Figures 1a-e, Tables 1a-e). The\naerial survey protocol for Cape Cod Bay, as described in Kraus et al (1997),\nwas adopted with some modifications. Fifteen tracklines were flown\nlatitudinally (east - west) at 1.5 nautical mile (nm) intervals from the\nmainland to the Cape Cod Bay shoreline (Figure 1a). An additional trackline,\n25 nm in length, paralleled the outer coast of Cape Cod from east of Chatham\nto the eastern end of trackline one at a distance of about three nm from shore\n(Figure 1a, trackline number 16). The east-west flight pattern in Cape Cod Bay\nwas chosen for scientific and safety reasons. In these latitudes, winter\naerial surveys are hampered by low sun angles in the early and late hours of a\nsurvey day and glare is a significant factor in sightability of marine\nmammals. On east-west tracklines, although glare was a factor in one of the\nforward quadrants, there was always a section of the survey swath that could\nbe observed without being compromised by glare. It was also safer to have the\naerial survey tracklines begin and end near land. A total of 320 nm of 'on-\ntrackline' miles were flown during each completed survey (Table 1a). \\\"On-\ntrackline\\\" miles were those miles flown while surveying due east or due west\nin Cape Cod Bay and along the outer coast of Cape Cod, but excludes all miles\nflown between tracklines (cross legs) or while circling.\n \nThe surveys were flown under VFR (visual flight rules) conditions up to and\nincluding Beaufort sea state four. Surveys were aborted in Beaufort sea state\nfive and/or when visibility decreased below two miles in fog, rain or snow.\nAll aerial surveys originated at Chatham Airport, Chatham, MA. They were\nconducted in a Cessna 337 Skymaster (5382S), a twin engine, high-wing aircraft\nwith retractable landing gear. The aircraft was equipped with two GPS (global\npositioning system) navigation systems, full IFR (instrument flight rules)\ninstrumentation, marine VHF radio with external antenna, and wing-tip mounted\nVHF tracking antennas. Safety equipment included a life raft, four survival\nsuits, signal flares, a medical kit, a waterproof VHF radio, a portable EPIRB,\nand an aircraft mounted ELT (emergency locator transmitter). All occupants\nwore aircraft approved PFDs (personal floatation device) during the entire\nflight.\n \nSurveys were conducted at a standard altitude of 750 feet (229 meters) and a\nground speed of approximately 100 knots, using methodology developed by CeTAP\n(Scott and Gilbert 1982, CeTAP 1982). The survey team consisted of a pilot,\ndata recorder, and two observers positioned on each side of the aircraft in\nthe rear seats. The two rear seat observers scanned the water surface from\n0\\u00b0 - 90\\u00b0, out to at least two nautical miles and reported sightings\nwhen they were abeam of the aircraft. In order to maintain a standardized\nsighting effort, the pilot and data recorder were instructed not to alert the\nobservers to any sightings of marine mammals until after it had been passed by\nthe aircraft and clearly missed by the observers. The turn at the end of each\ntrackline was initiated and completed about 1.5 nm from shore in Cape Cod Bay\nto maximize the opportunity to observe any whales near shore.\n \nAll sightings of marine animals except birds were recorded. Sightings\nidentified as species other than right whales were counted, logged and passed\nwithout breaking the trackline and circling in order to maximize flight time\navailable for investigating right whale sightings. Sightings of all vessels in\nthe area were recorded by location and type. At sightings identified as right\nwhales, as well as sightings of large whales, which were not immediately\nidentified by species, the aircraft broke track at right angles to the\nsighting and circled over the animal to obtain photographs. Photographs were\nobtained of as many individual right whales within a given aggregation as\npossible. For each right whale, behavior and interaction with other whales or\nany nearby vessels or fishing gear was noted. In a few instances, when right\nwhales were spotted from the plane in close from the vessel so that the plane\ncould devote more time to surveying. The right angle distance of each sighting\nfrom the flight track was determined from GPS positions.\n \nAt the conclusion of photographic effort at each sighting, the aircraft\nreturned to the trackline at the point of departure using the GPS position\nrecorded in the log. These methods conform to research protocols followed by\nthe North Atlantic Right Whale Consortium (CCS, NEAq, URI, and WHOI) and\napproved by the US NMFS. Trackline and sighting data from the daily logs were\nentered into the Right Whale Initiative DBase program designed for\ncompatibility with the Right Whale Consortium database. Copies of the daily\nlogs from the aerial surveys are on file at CCS and URI.\n \nPhotographic Methods  \n i) Identification Photographs:  \n During aerial and shipboard surveys, photographs were taken on Kodak\nKodachrome 200ASA color slide film, using hand-held 35-mm cameras equipped\nwith 300-mm telephoto lenses and motor drives. From the air, photographers\nattempted to obtain good perpendicular photographs of the entire rostral\ncallosity pattern and back of every right whale encountered as well as any\nother scars or markings. From the boat, photographers attempted to collect\ngood oblique photographs of both sides of the head and chin, the body and the\nflukes. The data recorder on both platforms was responsible for keeping a\nwritten record of the roll and frame numbers shot by each photographer in the\ndaily log.\n \nii) Photo-analysis and Matching:  \n Photographs of right whale callosity patterns are used as a basis for\nidentification and cataloging of individuals, following methods developed by\nPayne et al (1983) and Kraus et al (1986). The cataloging of individually\nidentified animals is based on using high quality photographs of distinctive\ncallosity patterns (raised patches of roughened skin on the top and sides of\nthe head), ventral pigmentation, lip ridges, and scars (Kraus et al 1986).\nNEAq has curated the catalogue since 1980 and to the best of their knowledge,\nall photographs of right whales taken in the North Atlantic since 1935 have\nbeen included in NEAq's files. This catalogue allows scientists to enumerate\nthe population, and, from resightings of known individuals, to monitor the\nanimals' reproductive status, births, deaths, scarring, distribution and\nmigrations. Since 1980, a total of 26,275 sightings of 436 individual right\nwhales have been archived, of which 327 are thought to be alive, as of\nDecember 2001 (A. Knowlton, NEAq, pers. comm.)\n \nThe matching process consists of separating photographs of right whales into\nindividuals and inter-matching between days within the season. To match\ndifferent sightings of the same whale, composite drawings and photographs of\nthe callosity patterns of individual right whales are compared to a limited\nsubset of the catalogue that includes animals with a similar appearance. For\nwhales that look alike in the first sort, the original photographs of all\nprobable matches are examined for callosity similarities and supplementary\nfeatures, including scars, pigmentation, lip crenulations, and morphometric\nratios. A match between different sightings is considered positive when the\ncallosity pattern and at least one other feature can be independently matched\nby at least two experienced researchers (Kraus et al 1986). Exceptions to this\nmultiple identifying feature requirement include whales that have unusual\ncallosity patterns, large scars or birthmarks, or deformities so unique that\nmatches from clear photographs can be based on only one feature. Preliminary\nphoto-analysis and inter-matching was carried out at CCS, with matches\nconfirmed using original photographs cataloged and archived at NEAq.\n \niii) Photographic Data Archiving  \n Upon completion of the matching process, all original slides were returned\nto CCS and incorporated into the CCS catalogue of identified right whales to\nupdate existing files, using the same numbering system as NEAq, in archival\nquality slide sheets. New England Aquarium (NEAq) archives copies of\nphotographs representing each sighting. Copies of photographs of individuals\nthat are better than existing records, and photographs of newly identified\nwhales, will be included in the NEAq master files as \\\"type specimens\\\" for\nfuture reference. The master files are maintained in fireproof safes at NEAq.\nAll catalogue files are available for inspection and on-site use by\ncontributors and collaborators.
