abstract = "The Alaska Amphibious Community Seismic Experiment (AACSE) is a shoreline-crossing passive- and active-source seismic experiment that took place from May 2018 through August 2019 along an ∼ 700 km long section of the Aleutian subduction zone spanning Kodiak Island and the Alaska Peninsula. The experiment featured 105 broadband seismometers; 30 were deployed onshore, and 75 were deployed offshore in Ocean Bottom Seismometer (OBS) packages. Additional strong-motion instruments were also deployed at six onshore seismic sites. Offshore OBS stretched from the outer rise across the trench to the shelf. OBSs in shallow water (< 262 m depth) were deployed with a trawl-resistant shield, and deeper OBSs were unshielded. Additionally, a number of OBS-mounted strong-motion instruments, differential and absolute pressure gauges, hydrophones, and temperature and salinity sensors were deployed. OBSs were deployed on two cruises of the R/V Sikuliaq in May and July 2018 and retrieved on two cruises aboard the R/V Sikuliaq and R/V Langseth in August-September 2019. A complementary 398-instrument nodal seismometer array was deployed on Kodiak Island for four weeks in May-June 2019, and an active-source seismic survey on the R/V Langseth was arranged in June 2019 to shoot into the AACSE broadband network and the nodes. Additional underway data from cruises include seafloor bathymetry and sub-bottom profiles, with extra data collected near the rupture zone of the 2018 Mw 7.9 offshore-Kodiak earthquake. The AACSE network was deployed simultaneously with the EarthScope Transportable Array (TA) in Alaska, effectively densifying and extending the TA offshore in the region of the Alaska Peninsula. AACSE is a community experiment, and all data were made available publicly as soon as feasible in appropriate repositories.",

note = "Funding Information: The Alaska Amphibious Community Seismic Experiment (AACSE) project was funded by NSF award OCE-1654568 to Cornell. Instrumentation onshore was provided by the Incorporated Research Institutions for Seismology-Portable Array Seismic Studies of the Continental Lithosphere (IRIS-PASSCAL) Instrument Center. Offshore instrumentation was provided, upgraded, and deployed by the Woods Hole Oceanographic Institution (WHOI) and Lamont-Doherty Earth Observatory (LDEO) Ocean-Bottom Seismometer Instrument Pools (OBSIPs) and recovered by the successor WHOI OBS Instrument Center. Assistance from the U.S. Geological Survey's Alaska Volcano Observatory was invaluable to deployment on the Alaska Peninsula. The support staff of the R/V Sikuliaq and R/V Marcus G. Langseth provided support offshore, and numerous agencies and landholders supported the project onshore. Bill Danforth and Dave Foster contributed substantively to planning, analysis, and processing of the underway multibeam and sub-bottom profiler data collection. Paul Johnson, Joan Gomberg, and Susan Hautala organized the collection and archival of OBS-mounted temperature and salinity data. The authors thank the editor and reviewers for their valuable suggestions to improve the article. Finally, the authors thank student volunteers for assistance in the field with node deployment and recovery on Kodiak Island.
