PIROP Northwest Atlantic
Entry 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. ... View entire text

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.

Quality ATTRIBUTE ACCURACY REPORT: Sightings are referenced to the observer, the specific cruise and ship name, ship speed, time and date. Accuracy of bird ID and bird numbers are reported and presented in the database. For geo-referencing, normally there was no GPS available (but LORAN and ship navigation); few scientific names and classification has changed, e.g. subspecies. LOGICAL CONSISTENCY REPORT: ...
