Alaska Amphibious Community Seismic Experiment

Alaska Amphibious Community Seismic Experiment

The Alaska Amphibious Community Seismic Experiment (AACSE) is an
offshore-onshore passive source seismic experiment designed to
investigate the processes that govern subduction, earthquakes,
and volcanism along the Alaska Peninsula.

We will deploy 75 Ocean Bottom Seismometers (OBSs) from OBSIP
and 30 onshore broadband instruments from the PASSCAL Instrument
Pool. Thirty of the OBSs will be provided by WHOI (to be
deployed in July 2018) and the remainder by LDEO (to be deployed
in May 2018). OBS deployments will take place on the R/V
Sikuliaq (link)

The experiment is concurrent with the EarthScope USArray
Transportable Array (TA) and maximizes integrated use of TA
instruments, focusing on the eastern part of the subduction
system. The TA should remain fully deployed until some time in
mid-late 2019.

A dense transect crossing Kodiak and Katmai integrates with TA
stations 1000 km behind the arc. AVO is enhancing several Katmai
and Alaska Peninsula stations to broadband in coordination with AACSE.
