      FARALLONS CRUISE

      A survey of the Farallon Islands Radioactive Waste Dump site was

      recently completed using the NOAA ship McArthur. The survey

      was a collaboration among the U.S .Environmental Protection Agency,

      the U.S. Geological Survey, the British Geological Survey, and the

      Gulf of the Farallones National Marine Sanctuary. Approximately

      47,800 barrels of low-level radioactive waste were dumped at 3 sites

      between 1946 and 1970. The barrels litter a 1400-square-km area,

      most of which is now within the boundary of the Gulf of the

      Farallones National Marine Sanctuary. Previous studies in 1990,

      using SeaMARC 1A, identified objects on the seafloor at the site

      which were interpreted as barrels. This interpretation was confirmed

      by video footage during the sidescan cruise, and subsequently in 1994

      using the U.S. Navy submersible 'Sea Cliff' and the unmanned

      Advanced Tethered Vehicle. Systematic regional data on seafloor

      radioactivity were obtained on the McArthur using the BGS-towed

      sea-bed gamma-ray spectrometer (EEL) system. More localized data

      were also collected with the system at known sites of barrel clusters.

      Sediment samples were collected, both regionally and around the

      known barrel clusters, for subsequent laboratory analysis. Studies

      were focused on the shallower parts of the dump site where commercial

      fishing is carried out. About 90 line-km of EEL trackline were

      obtained in the shallowest part of the dump site (the '90 m site'),

      and 9 sediment samples were collected at locations determined

      by the variation in the EEL "signature". Approximately 80 line-km

      of EEL data were gathered in the intermediate-depth section of the

      site (the '900 m site') and extending towards the deepest part

      (the '1800m site'). Six sediment samples were collected on the

      tracklines at the 900-m site. In addition, 10 samples were collected

      clustered around known barrel clusters. The deepest EEL survey line

      was towed in 1500 m of water, extending the previous record for the

      system (600m) by a considerable margin. Preliminary interpretation

      of the data suggests that the observed variations in seafloor

      radioactivity can be attributed to geological features. There were no

      indications of man-made radioactivity, suggesting that, if present on

      a regional scale, it is only at very low levels. Further information

      will become available when data and sample analyses are completed.

      Participants on the cruise were Dave Jones and Phil Roberts (BGS),

      Dan Howard (GFNMS), and Bob Hall and Lynn Karr (USEPA) (who due to

      circumstances beyond our control, were replaced by Scott Faller (USEPA)),

      Pat Shanks (USGS-Denver), John Chin, Michael Hamer, Gita Dunhill,

      Fred Payne, and Herman Karl. MarFac, coordinated by Steve Wallace

      and Dave Hogg, as usual, provided excellent support in getting

      this cruise out to sea, and shipping equipment back to England.

      Owing to the efforts of all above, this cruise was highly successful,

      despite extremely adverse conditions. It is one cruise that Herman

      Karl is glad to have behind him, however! Of note, and of unknown

      significance, is that a rainbow appeared both at the start and end

      of the cruise, just as the McArthur sailed under the Golden Gate.
