The Expedition - Science Crew Overview | Objectives | Science Crew | The Ship Principal Investigators Bob Pickart Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Bob Pickart is studying the processes by which water is transferred from the Beaufort shelf to the deep Arctic basin, using a densely-spaced mooring array situated across the shelfbreak and upper slope. His experiment is also part of the Shelf-Basin Interactions Program, and is closely tied to the Weingartner/Aagaard/Woodgate study, since much of the water exiting the Chukchi shelf enters the Beaufort shelf. In addition to the moorings, Pickart will do a high-resolution survey of the Beaufort boundary current system, using CTDs and XCTDs. Bob is the Chief Scientist on this cruise. Tom Weingartner University of Alaska, Fairbanks, Alaska Tom Weingartner and his colleagues at the University of Washington, Knut Aagaard and Rebecca Woodgate, are studying the circulation and water mass modification processes on the Chukchi shelf and slope as part of the Shelf-Basin Interactions Program. This will be done using a network of four moorings at critical locations on the Chukchi shelf, and additional CTD stations. Dean Stockwell University of Alaska, Fairbanks, Alaska Stockwell will be analyzing chlorophyll during the cruise. He will measure the chlorophyll concentrations in the Nikin bottle samples in near-real time. Stockwell will also be analyzing the fluorometer data (which provides a measurement of chlorophyll) from the CTD. Andreas Münchow University of Delaware, Newark, Delware Andreas will facilitate near real-time processing and interpretation of the vessel-mounted ADCP data aboard the Healy (in conjunction with CTD work). Dave Kadko Rosenstiel School of Marine and Atmospheric Science, Miami, Florida Dave is a marine geochemist; he utilizes naturally occuring radioisotopes to trace oceanographic processes. For this work he will be measuring radium isotopes in seawater to trace upper ocean currents, shelf-basin interaction, and eddy formation. WHOI Team Members John Kemp Woods Hole Oceanographic Institution, Woods Hole, Massachusetts John is the mooring technician responsible for redeploying the high-resolution Beaufort slope array. He designed the different moorings, and will oversee deck operations during their recovery. John has participated in over 150 oceanographic cruises totaling nearly 2000 days at sea. Jim Ryder Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Jim is a mooring technician. He will be assisting John Kemp in recovering the high-resolution Beaufort slope array. Dan Torres Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Dan will be collecting lowered ADCP data at each CTD station, which will provide a synoptic view of the velocity field during the cruise. Additionally, he is responsible for the programming and operation of the moored ADCPs being used in the high-resolution Beaufort slope array. Sarah Zimmermann Institute of Ocean Sciences, Sidney, British Columbia, Canada Sarah will be in charge of processing the CTD data collected on the cruise. This includes de-spiking and averaging the data, and then calibrating them using water sample measurements. Chris Linder Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Chris will document the daily discoveries and shipboard lives of the scientists and crew via the Arctic Edge website. He will write the text dispatches, take photographs, and update the website daily. In the dispatches this year he will also answer questions from junior high school students. In addition, he will help with programming tasks as needed. Jessie Cherry Lamont-Doherty Earth Obervatory, Columbia University, New York Jessie is a graduate student at Columbia University, studying Arctic climate and hydrology, with an emphasis on the Arctic freshwater budget.

She will be responsible for deploying and recovering the CTD and taking water samples from the Niskin bottles. Scripps Institution of Oceanography Team Members Dan Schuller Scripps Institution of Oceanography, San Diego, California Dan will be analyzing dissolved oxygen during the cruise. The CTD package contains two-dozen Niskin Bottles which will collect water at different depth levels in the water column; Dan will measure the concentration of dissolved oxygen in these samples in near-real time. Jim Schmitt Scripps Institution of Oceanography, San Diego, California Jim will be running the ship’s salinometer. This is an instrument used to measure the salinity (salt content) of the water samples collected by the CTD package. This information is needed to calibrate the CTD salinity sensor. Jim is also an electronics technician who will trouble-shoot and help repair any problems arising with the CTD. Erik Quiroz University of Southern Mississippi, Hattiesburg, Mississippi Erik will be analyzing nutrients during the cruise. The CTD package contains two-dozen Niskin Bottles which will collect water at different depth levels in the water column; Erik will measure the nutrient concentrations in these samples in near-real time. Rosenstiel School of Marine and Atmospheric Science, Miami Team Members Leopoldo Llinas Rosenstiel School of Marine and Atmospheric Science, Miami, Florida Leopoldo is studying the distribution and abundance of copepods and other pelagic zooplankton on the Western Arctic Ocean. Using a MultiNet to collect samples, he is looking at the advection of large-bodied copepods from the Bering Sea and Canada Basin onto the Chukchi and Beaufort shelves. Aaron Silverman Florida Institute of Technology, Melbourne, Florida Aaron will be helping Dave Kadko measure radium isotopes in seawater to trace upper ocean currents, shelf-basin interaction, and eddy formation. Jeremy Mathis Rosenstiel School of Marine and Atmospheric Science, Miami, Florida Jeremy is a graduate student working on a Ph.D. in chemical oceanography at the University of Miami. He has been a part of the Western Arctic Shelf-Basin Interactions (SBI) Program for the past two years working for his advisor, Dr. Dennis Hansell studying dissolved organic carbon (DOC). One of the goals of the SBI program is to gain a greater understanding of the distribution and dynamics of dissolved organic carbon (DOC) in the western Arctic Ocean; particularly in its variability and transport over the Chukchi Sea shelf, adjacent slope, and basin.
