This dataset contains the dive times (dive start time and dive end time) and depths (maximum depth attained on a dive) of three species of auk from the Isle of May outside the seabird breeding season.
Data were collected from 12 Atlantic puffin individuals (Fratercula arctica), 13 common guillemot (Uria aalge) and 13 razorbill (Alca torda).
Atlantic puffin data were collected between 19th July 2008 to 3rd December 2008; common guillemot data from 20th July 2005 to 28th January 2006; razorbill data from 1st July 2008 to 24th January 2009.

Data have been collected by Centre for Ecology & Hydrology (CEH) staff on the May National Nature Reserve, Scotland (56°11′N, 02°33′W) using standardised methods since 1987, and this work has continued to the present as part of the Isle of May Long-term Study (IMLOTS; https://www.ceh.ac.uk/our-science/projects/isle-may-long-term-study).
As part of this long-term study, data on seabird diving outside the breeding season was collected as part of a biologging project part-funded by the Royal Society for the Prevention of Cruelty to Animals. Data were collected using time-depth recorders during July – December 2008 for Atlantic puffins and razorbills and 2005 for common guillemots. The full methodology is available in the Supporting Information document attached to this record.
