Underwater sound data were collected from 13th June 2012 to 14th November 2013 providing 435 days of data (84% data coverage).
Acoustic data were not available from March to May 2013, as data were lost during recovery. Other gaps in data availability were due to weather conditions preventing access to the site for instrument recovery or servicing, or operational activity from the wave energy converter, for a total of 98 days.
The AMAR operated for a mean of 75 days per deployment (Table 1).
