SUCCESS ON THE HIGH SEAS OFF EUREKA
This week we completed a very successful 9-day survey aboard the RV WECOMA of
the shelf and slope offshore of Eureka in the area designated as the STRATAFORM
area. One of the major goals of the STRATAFORM Project is to gain a better
understanding of how strata are deposited, both in terms of the physical
processes and also in terms of the preserved acoustic signatures, such as
downlap, offlap, and toplap. A complementary goal is to learn how the signatures
combine to form characteristic stratigraphic sequences, such as drapes, aprons,
wedges, and sigmoids. An essential element to gain this understanding is the
analysis and interpretation of geometries of acoustic reflectors in the upper 50
m of the outer shelf and slope. The cruise aboard the WECOMA of Oregon State
University was the second in 10 months devoted to these goals and resulted in
over 1100 km of high-resolution seismic-reflection data using the Huntec DTS and
high-resolution sidescan sonar using the Datasonics SIS-1000 system.
Thanks to an excellent support team from Marfac, and at-sea support
extraodinaire from our John Gann and Tom O'Brien from Woods Hole, we achieved
all of our objectives, despite some LARGE waves and ubiquitous crab pots. The
results are outstanding from our viewpoint, and they should provide lots of new
insights for understanding the late Quaternary development of the shelf and
slope, particularly with regard to channel flows on slopes, the Humboldt
submarine slide, and tectonic deformation of late Quaternary deposits.
The data are being processed and archived at present. If you are interested
in more information, our cruise report, tracklines, and a few images are
available on the web at our marine facility page

walrus in the very near future. Mike Field amd Jim Gardner
