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.

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: ... Methods apparently changed after 1984 to follow closer Tasker et al. (1984) (from unlimited width transects to 300m wide strip-transects: 150m left and right). However, interpretation of data as index of relative abundance should not be affected for most species (e.g. as long as fully comparable conditions and species detectability is less than 150m). Potential biases could occur when birds flying by (snapshot counts' sensu' Tasker et al. 1984; see behaviour codes). Varying ship heights can affect how far seabird at sea can be detected. As described in the database, some transects are differing in length <> 10min and search effort (view angle <> 180 degrees forward). A minute transect consist of individual sightings; however, it needs to be assumed that some observers reported pooled sightings by species or transects. PIROP Database is split into two data sets, linked with a unique key field. PIROP dataset is divided into 4 octants (hemispheres). Time reference is made to Greenwich Time, not local or ship time. Ship speed is recorded to calculate seabirds per km transect. COMPLETENESS REPORT: Transects with confirmed absence are reported; however, absence need to be queried for 10minute transects where a specific species occurs but not another one (see Huettmann and Diamond 2001). High-turnover of observers might have included noise in the data. Some data and PIROP Notes were stored at BIO tapes, which were only in part recovered. Last data collected by R.G.B. Brown in the early 1990s were included into PIROP, also ferry and boat surveys off Grand Manan by F. Huettmann in the late 1990s (details Tony Lock). HORIZONTAL POSITIONAL ACCURACY REPORT: Latitude and Longitude (seconds). The 10 minute seabird transects were geo-referenced (latitude longitude, no seconds reported) at the beginning of each transect by the observer according to the ship log. If necessary, locations of specific observations within the 10 minute transect could be roughly obtained by extrapolating distance traveled using ship speed information. VERTICAL POSITIONAL ACCURACY REPORT: Ship cruise on water. Altitudinal variations are caused by tidal changes (irrelevant, occurs seldom), waves or ship height (both relevant e.g. view height of observer to detect seabirds). LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: PIROP was set up by Paul Germaine and R.G.B. Brown, folowing closely King et al. (1967). Data were collected in the field on paper and notebooks, and in the office coded and transcribed, and then checked. Earlier database versions were used, some data were stored on BIO tapes; now all data were transformed to the Visual FoxPro software by Tony Lock (CWS-Dartmouth and a contractor). Analytical tools, e.g. bins, were produced appr. 1994 in EXCEL by Steven Gerriets and Tony Lock. PIROP data were analysed by A.W. Diamond and processed and queried by Eric Woodsworth at CWS in Ottawa. A PIROP software and data-entry mask was produced by Tony Lock and contractors in 1998; coding was unified. Additional old data were frequently added, e.g. by Falk Huettmann in 1997. A hardcopy of all PIROP data (state: 1997) was produced by Falk Huettmann and is located at ACWERN (Atlantic Cooperative Wildlife Ecology Research Network) at the University of New Brunswick (UNB, Faculty of Forestry and Environmental Management). In 1998 the Manomet Bird Observatory Seabird-database was implemented by Tony Lock. 1999 PIROP was transferred to CWS-Sackville, John Chardine.
