  <Summary>
    <Abstract>Records of past climate and ocean circulation derived from marine sediments. Parameter keywords describe what was measured in this data set.  Additional summary information can be found in the abstracts of papers listed in the data set citations. 
          STUDY NOTES: Diatom counts from surface sediments of the Bering and Chukchi Seas. Sediments collected from either HAPS cores or Van Veen grabs (top 1 cm). 
      Provided Keywords: Bering Sea, diatoms, surface sediments</Abstract>
