Experiment Summary

(Taken from the cruise report): Profiles OBS01 and OBS02 are located over sedimented 22-28 Ma oceanic crust in the Gulf of Alaska. Primary features observed in the bathymetry and magnetics (Fig. 2) are the Kodiak-Bowie seamount chain, the Aja fracture zone, and a disruption in the magnetics which is identified by Atwater and Severinghaus [1989] as a small wandering offset. Profile OBS01 is located near the trace of the small wandering offset; profile OBS02 crosses the Aja fracture zone and the Kodiak-Bowie seamount chain.

14 WHOI ocean-bottom seismometers were deployed in two lines of 7 instruments on board the R/V Langseth. One OBS was not recovered.

Data

Data from the ocean bottom seismometers will be archived at the IRIS DMC under temporary network code 1B (2011) and assembled data set ID 11-017.
