PIROP Northwest AtlanticEntry ID: seamap280
Abstract: The PIROP (Programme Intégré de recherches sur les oiseaux pélagiques) data set, Atlantic subset, consists of geo-referenced vessel-based surveys to monitor pelagic seabirds. Most surveys were carried out by R.G. B. Brown from 'vessels of opportunity' supplied by the Bedford Institute for Oceanography (BIO) in Dartmouth/Halifax, but many other platforms and observers were used, too. During these ... surveys observations other than seabirds were also recorded, e.g. Waterfowl, Waterbirds, Songbirds, Raptors, Owls, Sea Mammals, and other sightings of interest (weather, oceanography, vessel activities, bird behaviour, etc.). The data collection period covers all seasons of 1966-1992, with most surveys being conducted between (late) summers of 1975-1987. The survey protocol originally consisted of unlimited width 10min transects, but was changed appr. 1984 towards a Tasker et al. (1984) type of survey (fixed-width strip transect). However, data and results from the PIROP database need to be interpreted as relative, and not absolute, abundance.
Purpose: The PIROP data were collected for Canadian seabird monitoring purposes, focusing on the Canadian Atlantic, but also on other areas relevant to Canadian birds such as waters off Peru, off West Africa and off Europe.
SUPPLEMENTAL INFORMATION: Puffinus creatopus (Pink-footed Shearwater; ITIS: 174547) observed on 1982-08-16 12:00:00 at 53.9000:-55.5000 (id=151664) changed to Procellariidae ... (Shearwaters; ITIS: 174532) as P. creatopus does not occur in the Atlantic. The PIROP data set is a large pool of seabird data, which got extended and modified over the years, e.g. due to changes of objectives and staff. Appr. in 1998 the data were merged by CWS-Dartmouth office with the Manomet Bird Observatory Seabird database, which cover mostly the Gulf of Maine region.
