      Notes -

      USGS contact: Mike Fisher

      (from 9/2/94 USGS Bulletin) During July the German research ship Sonne

      conducted geochemical and geophysical research in the Gulf of Alaska. Chief

      scientists Roland Von Huene and Ernst Flueh of GEOMAR in Germany were

      interested in measuring the flux of greenhouse gasses from the accretionary

      wedge near the Aleutian Trench. Multichannel seismic and Hydrosweep

      bathymetric data provided initial clues to locate potential fluid seeps, and

      the geochemists investigated likely sites using a video-camera sled. Although

      we found no obvious seeps, ever optimistic scientists hoped that the following

      cruise would identify additional sites for detailed analysis. Another research

      goal was to collect detailed seismic-velocity information from accreted rocks

      near the trench. From these data, geophysicists hoped to calculate gradients

      in the degree of compaction of accreted sediment as well as the volume of

      fluid expelled. The seismic source was two monstrous (2000 cu. in. each) air

      guns. Ten OBSs were deployed repeatedly with great success in this endeavor.

      Unfortunately, foul weather foiled our attempt to measure the seismic velocity

      of highly reflective rocks that form the middle and lower crust of the

      accretionary complex near lower Cook Inlet. The highlight of the cruise came

      with our realization that enigmatic features in USGS and Hydrosweep data

      revealed collision scars that resulted from subduction of seamounts and

      collision of the Yakutat terrane. Mike Fisher


      Similar information is available for thousands
      of other USGS/CMG-related Activities.

      If known, available are Activity-specific
      navigation, gravity, magnetics, bathymetry,
      seismic, and sampling data; track maps; and
      equipment information; as well as summary
      overviews, crew lists, and information
      about analog materials.

      described in the "WR CMG Sample Distribution
      Policy" at:
