The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String 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). New
England Aquarium (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of 436 individual right whales have been archived, of which 327 are thought to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. 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.
