Advisors: Dr. Julie Brigham-Grette and Dr. Ross Powell

  • Learned to perform and interpret a variety of field sedimentology and physical oceanography techniques during 6-week field season in Svalbard
    1. CTD/OBS Casting – Salinity, temperature, water clarity vertical thermocline
    2. Sediment Coring – 24″-36″ column of sediment layers from seafloor
    3. Grab Sampling – Water and sediment sample of seafloor surface
