The survey consisted of several techniques including acoustic recording tag, visual survey, photo-ID, DNA sampling, behavioral observation and fecal sampling. This data set is the result of the visual survey. In total, 30 sightings of sperm whale were recorded in a 30 day survey period.

As such, the biological data on sperm whale is required to produce stock assessment reports. This survey was the pilot study to test and refine a wide range of sperm whale research techniques in Gulf of Mexico. The survey will contribute to answering the following research questions. 1. What are the effects of anthropogenic noise on the distribution, behavior and vocalization patterns of sperm whales? 2. What is the stock status of sperm whales that inhabit the Gulf of Mexico compared to the adjacent Atlantic Ocean and Caribbean Sea? 3. Will surveys using both acoustic array methods and visual surveys improve the NMFS's abundance estimates of sperm whales in the U.S. Gulf of Mexico? 4. Is the group composition and social structure of sperm whales in the Gulf of Mexico similar or different compared to sperm whales in other parts of the world? 5. How do sperm whales spatially use the Gulf of Mexico? Are there specific feeding, breeding, socializing and resting areas? notPlanned Lance Garrison NOAA Southeast Fisheries Science Center Primary contact lance.garrison@noaa.gov NA NA NA Lance Garrison owner NA zd_96 2025-07-31T14:03:57-04:00 dataset Garrison, L. 2020.
