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, focussing on the Canadian Atlantic, but also on other areas relevant to Canadian birds such as waters off Peru, off West Africa and off Europe.

[2020-08-18] Atlantic spotted dolphins and Pantropical spotted dolphins were associated with opposite scientific names and ITIS TSNs. This error is fixed. 

[2015-03-24] Some records had a wrong animal count of zero. The value is replaced with a blank representing species presence only.

Data correction: 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 has effort data which is not as complete as to generate tracklines. It's available upon request and you are strongly encouraged to discuss with the data providers how to handle the effort data.

The PIROP data set is a large pool of seabird data, which
