Summary

Recent changes in oceanography and human demography prompted a need for updated information regarding at-sea populations of seabirds in the Bight. Techniques were used that would allow comparison with previous seabird surveys conducted by Briggs et al. (1987).

Description

Aerial at-sea and coastal surveys were conducted to examine the distribution and abundance of seabirds off Southern California, from Cambria, California to the California-Mexico border and including the area 90 to 180 km from the shoreline. From May 1999 to January 2002, nine complete aerial surveys were flown throughout the survey area, with monthly replicated (n=2 per month/year) surveys flown throughout the central portion (e.g., area surrounding the northern Channel Islands). In total, flights occurred on 102 days, covering over 54,640 km of transects throughout the entire Southern California Bight (Bight) during January, May, and September. A total of 135,545 birds were counted and identified, comprising 54 species in 12 families.

Credits

Extensive fieldwork in 1999-2002 was conducted jointly by the U.S. Geological Survey (Western Ecological Research Center, Vallejo and Dixon, California; Principal Investigators J.Y. Takekawa and D.L. Orthmeyer) and Humboldt State University (Department of Wildlife, Arcata, California; Principal Investigators R.T. Golightly and H.R. Carter; Project Leader: G.J. McChesney). Major contributions to fieldwork were made by J. Mason and W. McIver. Significant contributions to data analyses were made by W. Perry, J. Yee, J. Adams, and J. Ackerman. Major project cooperators included Minerals Management Service (M. Pierson, M. McCrary) and the U.S. Navy (S. Schwartz, T. Keeney), and California Department of Fish and Game (P. Kelly, E. Burkett).

Supplemental information
This file contains the species observations summarized as monthly averaged densities for all marine birds (birds/km squared) scaled to 5 minute blocks of latitude-longitude grid cells. Surveys for seabirds were coincident with marine mammal surveys and were flown at 60 m (200 ft) above sea level at 160 km/hr (90 knots) ground speed. The surveys were flown in a high-winged, twin engine Partenavia PN 68 Observer aircraft following methods developed for aerial seabird surveys by Briggs et al. (1987). GPS points were recorded every five seconds to limit the size of the resulting data files and to allow adequate spatial coverage to delimit individual tracklines (225 m is traversed every five seconds at the survey speed of 160 km/hr). Data were collected using a laptop computer running Program dLOG (R.G. Ford Consulting, Inc.). Observers sat on both sides of the aircraft and scanned the sea surface through bubble windows. Each of two observers counted and identified all seabirds within a 50 meter strip on both sides of the aircraft (total strip width equal to 100 meters when both observers were surveying simultaneously). Observations were confined to one observer (one side equal to 50 m strip width) when glare obscured > 25% of the second observer's field of view. To ensure a strip width of 50 meters, observers estimated sighting angles from the aircraft to the water using clinometers. Observers rechecked sighting angles with a clinometer several times during each survey. Marine bird densities for all birds present, including those sitting on the water and flying through the transect, were calculated for transect segments generated by intersection with a parent 5 minute latitude-longitude grid. The resulting density for each species (e.g., Western Gull) or taxon grouping (e.g., Gulls) was then ascribed to the unique grid cell that incorporated the trackline segment. Each grid cell was surveyed from 1 to 6 times for a given month during the three year survey (January 2000, 2001, 2002; May 1999, 2000, 2001; September 1999, 2000, 2001). For cells adjacent to mainland and island coastlines (coastal) all densities are from surveys flown parallel to shore (i.e., densities calculated for cells from perpendicular offshore transect segments that intersected the coastline were not included in the calculation of averages for coastal cells). Seabird observations were recorded on audiotape using hand-held tape recorders. Animals were identified to species or nearest taxon. Exact counts were made for solitary individuals or small groups and estimated numbers for groups > 10. For each observation, time was recorded to the nearest second, along with species and number. Observers also noted behavior (e.g. flying or sitting on the water) and flight direction; however, these data are not reported here. Each observer transcribed data from audiotape onto standardized data forms and entered data into the computer program SIGHT (Micro Computer Solutions, Portland, OR, USA). SIGHT was used because it had preset data entry protocols that helped to ensure entry accuracy. Two people checked data entry for accuracy by printing SIGHT data for comparison with transcribed forms. REFERENCES: BRIGGS, K. T., W. G. Tyler, D. B. Lewis, and D. R. Carlson. 1987.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Conceptual consistency
Measure description
Following each survey, transect points were plotted using ArcView and checked for GPS errors or missing data.




Data quality report - Completeness omission
Measure description
Following each survey, transect points were checked for accuracy and completeness. In some cases, due to computer or GPS problems, sections of the transect were not captured. These sections were later recreated based on known waypoints and constant airspeed using interpolation programs written in SAS. Those added points are identified in the attribute table. (see attribute field Rectype, value = 'SAS').




Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description
Transect points were captured using a Garmin 12 + GPS. Positional accuracy assumed to be within 100 meters.
