An omnidirectional Ocean Sonics icListen hydrophone (SB2-ETH, SN 1713) recorded continuously at 512 kilosamples/second (256 kHz Nyquist frequency; 24 bit) for 2 years. The hydrophone was mounted vertically on a steel strut (insulated with rubber sheet) at about 70 cm above the mud/gravel seabed at 21m deep, with the sloping 45\u00b0 rubble face of the jetty just behind the hydrophone. Temporal coverage is \u003e90%, with gaps and truncated files arising due to network and power outages and software bugs. The audio recordings are 10 minute WAV files, compressed using the lossless FLAC code (Free Lossless Audio Codec, xiph.org; about 33MB of data/minute compressed; 100MB/min uncompressed). The hydrophone was under thick (to 3 m) sea ice cover for the majority of the dataset. The majority of the recorded biological sounds were produced by Weddell seals. Orca were present intermittently (~10 days total) in January-March in both summers. Known non-biological sounds include irregular low-intensity, broad-spectrum clicks and cracks from the sea ice cover, occasional wind noise, a 1.5-s gurgle with components to 200kHz every 90s from the CTD\u2019s pump, a broad-spectrum mechanical sound for 3 min every 4 h from the observatory\u0027s underwater camera cleaning system, low-intensity whines (about 18, 58, 83, and 130 kHz, though variable over the dataset) thought to be from the station seawater pumps (\u003e100 m away within the jetty\u2019s well casing), and intermittent noises from tracked-vehicles and helicopters (September\u2013February), SCUBA divers (October\u2013December), and ships (January).

However, little is known regarding their distribution and behavior, in part because of challenges associated with studying these organisms from large research vessels. This research will take advantage of the unique opportunity presented by the 2012-2013 test run of the smaller, more mobile R/V Point Sur. This work will use the Point Sur to investigate humpback whales in the waters studied by the Palmer Long Term Ecological Research (LTER) Station off the Western Antarctic Peninsula (WAP). Employing a combination of long-term satellite-linked tags and short-term suction cup tags, researchers will investigate the distribution, abundance and foraging behaviors of whales in this region. Whale biogeography will then be related to quantitative surveys of krill, their primary food source. Hypotheses regarding whale distribution and foraging strategies as well as physical oceanographic features will be tested. The WAP is undergoing some of the most dramatic warming on the planet, and a better understanding of the ecology of top predators is central to developing an understanding of the impacts of this change. Results will be widely disseminated through publications as well as through presentations at national and international meetings. In addition, raw data will be made available through open-access databases. Finally, this work will be coordinated with the extensive infrastructure of the Palmer LTER site, enabling outreach and educational activities.\n", "east": -60.0, "geometry": ["POINT(-70 -66.5)"], "keywords": "Antarctica; Antarctic Peninsula; Biota; Oceans; Sample/collection Description; Sample/Collection Description; Southern Ocean; Whales", "locations": "Antarctic Peninsula; Southern Ocean; Antarctica", "north": -63.0, "nsf_funding_programs": null, "persons": "Friedlaender, Ari; Johnston, David; Nowacek, Douglas", "project_titles": "RAPID: Linking the Movement Patterns and Foraging Behavior of Humpback Whales to their Prey across Multiple Spatial Scales within the LTER Study Region", "projects": [{"proj_uid": "p0000666", "repository": "USAP-DC", "title": "RAPID: Linking the Movement Patterns and Foraging Behavior of Humpback Whales to their Prey across Multiple Spatial Scales within the LTER Study Region"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -70.0, "title": "Linking the Movement Patterns and Foraging Behavior of Humpback Whales to their Prey across Multiple Spatial Scales within the LTER Study Region", "uid": "600151", "west": -80.0}]
