attribute	NC_GLOBAL	acquisition_description	String	Vessel Surveys: CCS maintains a 40' (12m) long, twin diesel engine research vessel Shearwater. The R/V Shearwater has been used successfully for oceanographic sampling and photo-identification in the winter and spring surveillance program in Cape Cod Bay from 1997 through 2002. The R/V Shearwater is equipped with oceanographic sampling equipment including a CTD profiler (conductivity, temperature, depth), plankton nets, surface plankton pump, and flow meter as well as photographic equipment and disentanglement gear. Although the primary objective of these vessel cruises was habitat sampling, some photographs were collected opportunistically of right whales in the vicinity of the boat during sampling and on transits to and from sampling sites. Photographs of right whales obtained during habitat studies were integrated with the photographs collected during aerial surveillance and included in this report in analyses of residency, capture rates, demographics, and life history. The vessel sighting data were included in the report to the NMFS/SAS system. Sighting data from the daily vessel logs were entered into the Right Whale Initiative DBase program as opportunistic surveys. Photographic Methods i) Identification Photographs: During aerial and shipboard surveys, photographs were taken on Kodak Kodachrome 200ASA color slide film, using hand-held 35-mm cameras equipped with 300-mm telephoto lenses and motor drives. From the air, photographers attempted to obtain good perpendicular photographs of the entire rostral callosity pattern and back of every right whale encountered as well as any other scars or markings. From the boat, photographers attempted to collect good oblique photographs of both sides of the head and chin, the body and the flukes. The data recorder on both platforms was responsible for keeping a written record of the roll and frame numbers shot by each photographer in the daily log. ii) Photo-analysis and Matching: Photographs of right whale callosity patterns are used as a basis for identification and cataloging of individuals, following methods developed by Payne et al (1983) and Kraus et al (1986). The cataloging of individually identified animals is based on using high quality photographs of distinctive callosity patterns (raised patches of roughened skin on the top and sides of the head), ventral pigmentation, lip ridges, and scars (Kraus et al 1986). NEAq has curated the catalogue since 1980 and to the best of their knowledge, all photographs of right whales taken in the North Atlantic since 1935 have been included in NEAq's files. This catalogue allows scientists to enumerate the population, and, from resightings of known individuals, to monitor the animals' reproductive status, births, deaths, scarring, distribution and migrations. Since 1980, a total of 26,275 sightings of 436 individual right whales have been archived, of which 327 are thought to be alive, as of December 2001 (A. Knowlton, NEAq, pers. comm.) The matching process consists of separating photographs of right whales into individuals and inter-matching between days within the season. To match different sightings of the same whale, composite drawings and photographs of the callosity patterns of individual right whales are compared to a limited subset of the catalogue that includes animals with a similar appearance. For whales that look alike in the first sort, the original photographs of all probable matches are examined for callosity similarities and supplementary features, including scars, pigmentation, lip crenulations, and morphometric ratios. A match between different sightings is considered positive when the callosity pattern and at least one other feature can be independently matched by at least two experienced researchers (Kraus et al 1986). Exceptions to this multiple identifying feature requirement include whales that have unusual callosity patterns, large scars or birthmarks, or deformities so unique that matches from clear photographs can be based on only one feature. Preliminary photo-analysis and inter-matching was carried out at CCS, with matches confirmed using original photographs cataloged and archived at NEAq. iii) Photographic Data Archiving Upon completion of the matching process, all original slides were returned to CCS and incorporated into the CCS catalogue of identified right whales to update existing files, using the same numbering system as NEAq, in archival quality slide sheets. New England Aquarium (NEAq) archives copies of photographs representing each sighting. Copies of photographs of individuals that are better than existing records, and photographs of newly identified whales, will be included in the NEAq master files as \"type specimens\" for future reference. The master files are maintained in fireproof safes at NEAq. All catalogue files are available for inspection and on-site use by contributors and collaborators.
