Abstract    

     This award will support detailed studies of contemporary climate,
     hydrology, limnology, and sedimentology in high arctic meromictic lakes in
     order to characterize the nature of modern sediment influx and deposition in
     relation to contemporary climate.  These process studies will be conducted in
     coordination with recovering cores of laminated lake sediments from the
     meromictic lakes.  The sediments will be studied to determine if the
     laminations represent annual increments and if they can be related to recent
     climatic conditions in the area.  If so, longer sedimentary records will be
     used to reconstruct past climate in the region.  Since there are few sources of
     paleoclimatic data with annual resolution from the high arctic, this study will
     evaluate the potential of using laminated lake sediments for high resolution
     paleoclimatic reconstruction.
