Summary
WWC collected a grid of vibracores as well as the deep borings. Both
         were probably collected with barge mounted truck/vibracore and truck?/
         spider rig. Vibra cores were "continuous" and deep borings were not
         continuous but were "Campbell?" spot cores. All core samples were
         given to USGS when SF warehouse shut down. Clifton and Chin went to
         SF to pick up cores. Vibracores were put in reefer. Working half (now
         totally used up) went to Chuch Powell for megafossils, Mary McGann
         for microfauna (benthic forams), and Gretchen Luepke for mineral
         separates. Archive half was in Deer Creek reefer until the move - now?
         The spot cores from the deep bores were highly dessicated when taken
         from SF warehouse. They were examined briefly and were left outside
         at MARFAC (and John does not know if they still exist now, and may
         not have been very useful--better to look at the stratigraphic logs
         in the WWC reports). John thinks the macrofauna are recycled
         transgressive lag sequences. To determine if fauna are in place, all
         vibracores would have to be xrayed and studied to look for fauna in
         growth postions--this would be a massive undertaking, albeit an
         interesting study, to also compare with lag sequences onshore. John
         is not sure that ages are possible, with recycled macrofossil lags
         and likely missing (or not preserved) microfauna in the sandy
         sequences. John says WWC reports have logs and stratigraphic sections.
         (Alan Cooper's notes of conversation with John Chin on 7/20 and
         7/28/97).

         12 crew
         10 borings totaling 616 ft.
         16 vibra coring totaling 183 ft.
         16 cone penetrometer tests 4 to 20 ft. into seafloor
         Barge towed the Spider II to the first borehole site on 4/5/77.
         Spider II completed boring on 4/22/77.
         Caldrill I began boring 5/13/77 and ended 5/28/77.
         Derrick barge dredged test pits nos. 1 and 2 from 8/17/78 to 10/9/78.
         Polaris I monitored bathymetry and side scan sonar from 8/21/78 to
         11/16/78.
Notes
Woodward Clyde Consultants collected seismic data and samples.
         Dave McCulloch looked at the seismic. Ed Clifton and John Chin and
         Gretchen Luepke worked on the sediments. Ed Clifton asked a Spanish
         student? to look at the seismic data, but he was unable to do anything
         with the stratigraphy. John has only looked at 4-5 of the seismic
         lines, does not know what McCulloch did (or published) with his
         analyses. John gave Gretchen all of his materials directly before
         the move. On one occasion, he gave her 6-7 binders of the WWC report.
         Then he gave her a box with his notes, xrays, and overlays, etc.,
         from the Chin/Clifton work. He also told Gretchen to deal with the
         cores and materials. (NB: Becky got 3 preliminary reports from
         Gretchen on/about 7/20. Becky later got a large stack of reports).
