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

Bar LoungeBedroom Gym

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

Palmer Station B E Boating Map of the Palmer Station Area including our sampling stations B & E

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 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
