Antarctic Summer • 2008-2009 • Scientific exploration of the Antarctic Peninsula
Elizabeth Leonardis age: 28 years old from: New York City undergrad: UC Santa Barbara grad: starting Fall 2009 profession: Nurse/Lab Technician • L. Alex Kahl • age: 29 years old • from: New York City • undergrad: UC Santa Barbara • grad: Rutgers University • profession: Oceanographer
Palmer Station • The U.S. research station where we will be living and conducting research for the next 6 months • Accessible only by ship, a 5 day journey from Punta Arenas, Chile • Currently 21 employees and 5 scientists living on station for the summer season • Station has many luxuries including comfortable rooms, a gym, bar and 24hr internet connection
Gym Bar Lounge Bedroom
Using our zodiac “Bruiser”, we travel to stations B & E for collection of: • Phytoplankton samples • bio-optical characteristics (absorption, scattering of light) • physical properties (temperature, salinity) of seawater

photo: Scott Sternbach photo: Scott Sternbach Using a GPS for precise location we drive our zodiac to each sampling station Go-Flow bottles are lowered using a winch on the zodiac to collect seawater samples at different depths
Bio-optical measurements are taken in the field by lowering a cage equipped with optical instruments that detect light utilized by phytoplankton • Real time data is collected that shows physical and bio-optical properties of the water column photo: Scott Sternbach
Back at the lab...... seawater is filtered for phytoplankton
Samples are then analyzed for: • - total chlorophyll • - pigment composition • - nutrients • - dissolved organic carbon • - flow cytometry • - DNA • - rate of photosynthesis Photo: Scott Sternbach
“Gliders” • Autonomous Underwater Vehicles (AUVs) • Gliders will be deployed from Palmer Station to study the properties of the water column in the Antarctic
Palmer Long-Term Ecological Research (LTER) Study An annual month long research cruise along the Antarctic Peninsula, Jan. 2009 Studying changes in sea ice, phytoplankton, zooplankton, and penguins photo: Nathan Hoople
The LTER is investigating ecosystem changes in response to climate warming and pole ward shifts in the climatic gradient Our focus on the LTER will be the phytoplankton/bio-optics component Gliders will be deployed and programed to follow the LTER research grid
