She is interested in specific mechanisms of cross-shelf transport and frontal interactions. Glen Gawarkiewicz Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Glen will be the chief scientist on the R/V Cape Henlopen this summer and the R/V Oceanus in Jan-Feb 2005. His team will be measuring the hydrography north of Diamond Shoals. Glen is interested in shelfbreak frontal dynamics, exchange of water masses between the continental shelf and slope, and learning about how marine mammals might be distributed relative to frontal systems in the Cape Hatteras area. Jim Churchill Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Jim will be on R/V Cape Henlopen cruise this summer and on the winter R/V Oceanus expedition. His interests are water mass exchange at the shelf-edge and the dynamics of Gulf Stream-shelf region interaction. Jay Austin Old Dominion University, Norfolk, Virginia Jay Austin will be responsible for the towed system measurements from the R/V Slover, Old Dominion University's research platform. He will produce real-time hydrographic sections from the towed surveys and from the ship underway measurements to assist in adaptively planning cruise tracks. He is interested in shelf circulation and cross-shelf transport mechanisms.   Skidaway Institute of Oceanography Team Members Trent Moore Skidaway Institute of Oceanography, Savannah, Georgia Trent Moore is preparing the Skidaway undulating CTD system for deployment, and will stand watch aboard the R/V Savannah mid-shelf cruise in Jan-Feb 2005 for ADCP and undulating CTD data collection. Julie Spector Brown University, Providence, Rhode Island Julie Spector is an undergraduate physics major at Brown University. As a summer intern at Skidaway, she will be examining SeaWiFS and MODIS imagery to estimate locations of the fronts near Cape Hatteras.   WHOI Team Members Frank Bahr Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Frank will be one of the Scanfish watch standers. He will run the data acquisition software to generate real-time visualizations of the Scanfish data and - with some luck - of the shipboard ADCP data as well. Craig Marquette Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Craig will be taking care of the mooring design and fabrication for Glen's ADCP mooring as well as coordinating with Dana Savidge for her moorings. Craig is also handling logistics for the WHOI instruments for both cruises. He will be setting up instruments, deploying, and recovering the moorings. During the cruise he will be standing a ScanFish watch. Chris Linder Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Chris will also man the Scanfish watch station. As time permits, he will additionally provide photographic documentation of the science activities. He is the outreach coordinator and webmaster for the project. Melanie Fewings Woods Hole Oceanographic Institution, Woods Hole, Massachusetts Melanie is a graduate student at MIT/WHOI. She will be one of the Scanfish watchstanders.   Old Dominion University Team Members Ann Gargett Old Dominion University, Norfolk, Virginia Ann originally suggested the addition of Freefall CTD casts to our data collection plans, for the purpose of estimating overturn scales. The size of density overturns can be used to estimate vertical mixing coefficients in the fronts. She has developed methodology and hardware requirements for shallow water deployment of this system, trained the PIs and science crew in their use, and will provide consultation support for data analysis. She and her group have been deeply involved in preparing us for the use of this developing and exciting new tool. Chris Powell Old Dominion University, Norfolk, Virginia Chris has developed a lightweight freefall winch system for shallow water deployment of the Freefall CTD, assisted in training for the use of the Freefall CTD system, and contributed to software development. Teresa Garner Old Dominion University, Norfolk, Virginia Teresa is a graduate student at ODU, working with Ann Gargett on the estimation of Thorpe Scales from CTD data. She will be primarily responsible for the collection and processing of Freefall CTD data on the R/V Henlopen. Shuang Huang Old Dominion University, Norfolk, Virginia Shuang is also a student at ODU, working for Ann Gargett on the development of acquisition and processing software for Freefall CTD data. Mark Santana Old Dominion University, Norfolk, Virginia Mark is an undergraduate at ODU, who will be helping Dana Savidge and Jim Churchill examine and define the tidal regime for the area from prior mooring data. He will also assist in the August cruises on the R/V Slover.   National Marine Fisheries Service Team Members Jon Hare National Marine Fisheries Service - Southeast Fisheries Science Center, Beaufort, North Carolina   Lance Garrison National Marine Fisheries Service, Miami, Florida Lance is the Marine Mammal Program leader at the Southeast Fisheries Science Center. His primary research areas include population monitoring and abundance estimation for marine mammals on the southeastern Atlantic coast and Gulf of Mexico. His current research focuses on the spatial distribution and abundance of Atlantic Bottlenose Dolphins, Pilot Whales, and Northern Right Whales in the southeast US calving grounds.   Duke University Team Members Andy Read Duke University Marine Laboratory, Beaufort, North Carolina Andrew Read is the Rachel Carson Chair of Marine Conservation Biology at Duke University. Andy's lab focuses on the conservation biology and ecology of marine vertebrates, with an emphasis on the life history and population dynamics of protected species, the application of spatial analysis to marine ecosystems, the intersection of oceanography and foraging ecology, and the development and application of new technological approaches to conservation. Andy will help his students analyze and interpret these observations. David Hyrenbach Duke University Marine Laboratory, Beaufort, North Carolina David is a researcher in Andy Read's lab, interested in the habitats of far-ranging pelagic vertebrates (seabirds, turtles, cetaceans), and the physical mechanisms (upwelling, convergence) that define predictable areas of enhanced biological activity in pelagic systems. David will help analyze and interpret the observations collected during these cruises. Erin LaBrecque Duke University Marine Laboratory, Beaufort, North Carolina For the past five years Erin has worked for various government and non-profit organizations collecting data on marine mammal abundance and distribution. Now she is joining the Read Lab as a master's student and will lead the observers during the summer and winter cruises. As part of her degree, Erin will analyze the distributions of upper trophic-level predators (marine mammals, birds and turtles) with respect to the mid-shelf front and other oceanographic features. Caroline Good Duke University Marine Laboratory, Beaufort, North Carolina Caroline has been a Ph.D. student in Andy Read's lab since 2003. She is interested in the use of spatial analysis techniques to develop information useful for marine mammal conservation and, where appropriate, area management. Beforehand, she worked with the National Marine Fisheries Service (NMFS) Marine Mammal Division at the headquarters office in Washington, DC. She will be conducting visual surveys for marine mammals, seabirds and turtles during the summer cruise. Lesley Thorne Duke University Marine Laboratory, Beaufort, North Carolina Lesley will be one of the marine mammal/ seabird observers on the cruise. Over the past few years, Lesley has worked on several projects out of the Grand Manan Whale and Seabird Research Station in the Bay of Fundy, and out of the Duke University Marine lab. Lesley plans to join the Crowder lab in 2005 to study food web assembly in a fine-scale oceanographic feature in the Bay of Fundy.   University of North Carolina, Chapel Hill Team Members Harvey Seim University of North Carolina, Chapel Hill, North Carolina As part of the Southeast Atlantic Coastal Ocean Observing System, Harvey has deployed a high-frequency radar system in northeast NC to examine the utility of this technology as a long-term monitoring tool. The radar will provide hourly estimates of surface currents between the entrance of Chesapeake Bay and Cape Hatteras and between 12 and 150 km offshore on a 6 km grid. It enables study of circulation on the shelf, shelfbreak, and slope, variability in the Gulf Stream front, and interactions between these areas, and is being used to characterize the flow in these regions. Interaction with the Cape Hatteras project will provide valuable ground truth measurements of currents in the footprint of the radar for calibration and validation studies. Brian Blanton University of North Carolina, Chapel Hill, North Carolina Brian has developed software that will allow us to extract tides from the underway ADCP data. The code interpolates ADCIRC model tidal predictions to ship tracks, and will allow us to examine velocities associated with the fronts as the data are collected. Tides typically dominate velocity variability, and would likely mask the frontal features in which we are interested, if they were not removed. Brian will also consult in a more careful post-cruise tidal extraction from the underway data.   ARMADA Team Member Catherine Roberts Western Branch Middle School, Chesapeake, Virginia Catherine Roberts will be joining the project as an ARMADA teacher. She is a 29 year veteran teacher of middle school science in Virginia. She will share her experiences with future students and her colleagues as a tool of cutting edge science to encourage inquiry learning in the classroom.
