  <Summary>
    <Abstract>Records of past climate and environment derived from lake sediment records.  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: Sediment biomarker (Uk&apos;37) and leaf wax hydrogen isotope (d2H) data from two lakes in the Brooks Range, Arctic Alaska. Data are interpreted for centennial- to millennial-scale trends in glacier extent and lake sedimentation in the Brooks Range.</Abstract>
