  1. Ongoing and Future Research Interests in the Arctic Lamont-Doherty Earth Observatory

  2. Marine Geology and Geophysics • J. Cochran Structure and development of Arctic basins and ridges Bathymetry (swath mapping), gravity, and magnetic measurements from submarines, ice breakers, AUVs • S. Goldstein Volcanism and magma formation along the Gakkel Ridge Collection of ridge samples by dredging and geochemical analysis of the samples • M. Tolstoy Environmental noise in the Arctic – marine mammals, sea ice deformation, seismic events Moored hydrophones • S. Webb Long-term broad band seismic measurements – monitoring global events in seismically quiet Canada Basin Seafloor broad band seismic sensor

  3. Physical and Chemical Oceanography • D. MartinsonSeasonal evolution of the surface mixed layer and halocline CTD measurements from ice camps and ice breakers, numerical models including sea ice formation • P. Schlosser, W. Smethie, B. Newton Freshwater origin and circulation in the Arctic Ocean Halocline and subsurface circulation of the ArcticOcean Arctic Ocean outflow to the Nordic Seas and formation of NADW CTD measurements, collection of water from submarines, ice breakers, ice camps, and aircraft and analysis for anthropogenic and freshwater tracers, numerical modeling • T. TakahashiCO2 uptake and transport out of the Arctic Ocean CO2, alkalinity, nutrient and oxygen measurements from seasonal cruises of the Iceland Marine Research Institute

  4. Paleoclimate and Paleoecology • P. BiscayePaleowinds from dust records in the Greenland Ice Sheet and modern day transport of dust to Greenland Chemical analysis of dust from the Greenland Ice core and from snow and firn to determine mineralogy and hence origin of dust • R. D’ArrigoArctic temperature record for past several hundred • G. Jacobyyears Tree ring analysis from Alaska, the Taimyr Peninsula and Siberia • D. PeteetAbrupt climate change, carbon sequestration and tree migration rates in Arctic wetlands Collection of sediments and analysis of pollen content Marine Biology • R. SambrottoNet biological production in Canada Basin from water column budgets of CO2 and O Respiration in the upper halocline CTD, florescence, nutrient and oxygen observations from submarines and ice breakers

  5. Ice • B. TremblaySea ice export form the Arctic Ocean Numerical models Thermal conductivity of snow and ice In situ measurements • S. PfirmanSea ice origin and flow paths Pollutant Transport by sea ice Satellite observations of sea ice Education • S. Pfirman Exploring the Poles - an undergraduate course for • R. Bell non-science majors. Covers climate, climate variability and the impact of climate variability • Most PIs Graduate and/or undergraduate students are involved in most research projects

  6. Concerns of LDEO Scientists about Arctic research • Funding for small (1-4 PIs) proposals • Ability to make time series observations • New Technology • Cabled Observatories • AUVs/ROVs • Access to the Arctic Ocean • Icebreakers • Aircraft • Submersibles • Long-term moorings
