Summary: | Original provider: Patricia Gozalbes Aparicio, Marine Zoology Unit, University of Valencia Dataset credits: Juan Antonio Raga, Marine Zoology Unit, University of Valencia Abstract: The study area comprised the waters of the Valencia and Murcia Regions (central Spanish Mediterranean), from the coastline to between 30 to 80 km offshore, with depths ranging from 10 m to 2,800 m. Seasonal line transect surveys were conducted from June 2000 to March 2003. Transects followed a systematic saw-tooth pattern that covered the area representatively (Buckland et al. 2001). The fieldwork platform was a high-wing aircraft (“push-pull” Cessna 337) flying at an altitude of 152 m (500 ft) and at a groundspeed of approximately 166 km/h (90 knots). Two observers, positioned on each side of the aircraft, scanned the sea surface and a recorder took note of data reported: species, number of animals, location (obtained from a GPS), time, and environmental conditions, including Beaufort sea state. Environmental conditions were ... |
