Summary
ABSTRACT: Aerial Surveys of Marine Birds And Mammals In Support Of Oil Spill Response And Injury Assessment Studies: -- OSPR Aerial Surveys [Birds and Mammals] Study Code: OS Contract Number: FG7407-OS with California Department of Fish and Game (CDFG), Office of Spill Prevention and Response (OSPR); and 14-35-0001-30758 (Task 13293) with the Coastal Marine Institute, University of ... California, Santa Barbara. PRINCIPAL INVESTIGATOR(S)/AFFILIATION: Michael L. Bonnell, Ph.D. Institute of Marine Sciences, University of California, Santa Cruz PURPOSE: OBJECTIVES: Develop and maintain a capability to provide aerial surveys of marine bird and mammal distribution and abundance for oil spill response and post-spill injury assessment. SUPPLEMENTAL INFORMATION: DATA COLLECTION: TIME PERIOD: June 1994 through October 1998 STUDY AREA: Coastal and inland marine waters of California. METHODOLOGY: Aerial surveys were conducted in a variety of California locales with experienced observers and trainees. The aircraft used was a Partenavia PN68 Observer provided by the Department of Air Services, CDFG, flown at an altitude of 200' (60m) above ground level and at a typical air speed of 90 kts. Two observers (at least one experienced) occupied middle seats and searched a corridor of 50m on each side of the aircraft. Width was defined by clinometer and simple trigonometric functions. Species, numbers, behavior and other information was described on hand-held tape recorders for later transcription and computer entry. The co-pilot position was occupied by a navigator/computer operator. This individual recorded number of observers on-watch, transect status (i.e., on-effort, off-effort, and commutes), as well as sea state, weather and other observation conditions. Date, time, and position of the aircraft were recorded directly into the data-logging computer with time, latitude and longitude provided by a Global Positioning System (GPS). DATABASES PRODUCED: A single database was produced including date, time, latitude/longitude, behavior, observation conditions, and other information for each sighting of marine birds, mammals, and turtles. As stated above, some surveys were solely for the purpose of drills and training, some for systematic data collection, and others for actual oil spill response. In this study, 74 one-day surveys were flown through 1997. Through the end of 1997, a total of 670 hours were flown and, exclusive of commutes, mapped bird and mammal distribution and abundance along 31,271 km (16,886 nmi) of transects. (data from several surveys from 1998 are yet fully analyzed and therefore not included on this CD-ROM.) Credit for this study is shared with OSPR by the Minerals Management Service (MMS), Pacific OCS Region, that provided most observers for surveys flown in Santa Barbara Channel and the Santa Maria Basin; MMS personnel also carried out tape-transcriptions and computer entry for surveys in southern California waters (this portion of the OSPR surveys was conducted under matching-funds between OSPR and the Coastal Marine Institute, University of California, Santa Barbara).
