Selection of clearest acoustic data of resident and transitory marine mammals at 230km north of the Falkland Islands. The data were collected in 2012, overwinter season.

The dataset comprises of the most clear wideband acoustic data from resident and transitory marine mammal populations recorded at 230km north of the Falkland Islands with 2 Autonomous Multichannel Acoustic Recorders (AMARs). Data have been collected by JASCO Applied Sciences (JASCO) which conducted a one year static acoustic monitoring programme between July 2012 and August 2013 on behalf of Premier Oil plc in the Sea Lion Development Area (SLDA). The aim of the programme was to establish by acoustic means, baseline conditions in terms of the spatial and temporal distribution of resident and transitory marine mammal populations prior to the commencement of oil and gas extraction activity. Additionally, the recording instrumentation was configured to provide high fidelity, calibrated measurements of ambient noise levels and third-party anthropogenic contributions to the soundscape. The acoustic data are provided with a text file including the description of the species and other comments made by Jasco data analysts. A detailed report entitled Static Acoustic Monitoring Programme for the Sea Lion Development Area. JASCO Document 00591, Version 1.0. Technical report by JASCO Applied Sciences for Premier Oil plc Falkland Islands Business Unit, is given with the data.

Lineage	The programme comprised 3 deployment phases each of approximately 4 months duration. During the entire programme a total of 12,192 hours (508 days) of wideband acoustic data and 26,410 hours (1100 days) of click detector data were recorded using 2 Autonomous Multichannel Acoustic Recorders (AMARs) and 3 C-POD cetacean click detectors. The instruments were deployed on specially designed subsurface moorings in water 410-420 m deep within the SLDA. The final dataset available summarises only the most clear and recognisable, as far as the species is concerned, acoustic files gathered across the whole field campaign. Six marine mammal species; 2 baleen whales, 4 toothed whales and 1 pinniped were detected as follows: Sperm whales; these were the most commonly detected species. Their interaction with the local Patagonian toothfish fishery could explain their regular occurrence. Fin whales; the second most commonly detected species that could be positively identified, frequently present from August to April. Pilot whales; commonly detected between April and August Killer whales; detections were rare and unpredictable. Southern right whales; rare but more commonly detected than in previous visual surveys. Leopard seals; detected between February and May, with a peak in March and April. A further species of odontocete was detected, but its identity remains unclear. This is largely due to incomplete descriptions of the vocal repertoire of species in the area.
