2014 Pilot Survey Cetacean Sightings

The dataset is a report describing how a line transect pilot survey for cetacean sightings has been designed and carried out in the Falkland Islands inshore waters in 2014. The pilot ship board line transect survey was developed with the intention of being implemented as part of a Darwin Initiative Project (ref EIDCF019).

Lineage	The survey area was defined as six strata between 300 m and 10 km from the Falkland Coastline. 10 days were available for conducting the survey. A systematic parallel line design was used to generate the survey and an additional design combining systematic parallel lines and zigzags was tested, however this design was dismissed because of a high percentage of overlap in the zigzag design corners. Both designs were generated using the software Distance. Using the available line length for conducting the survey and encounter rates of the target species from previous studies in Chile, the coefficient of variation of density was found to be 0.26 for Commerson’s dolphins and 0.34 for Peale’s dolphins. The coverage probabilities for the six strata were estimated using 5000 simulations of the design.
