![]() Long-term Ecological Monitoring, Antarctic Peninsula, Palmer Station Karen Baker. University of California - San Diego/Scripps Institute of Oceanography At the turn of the new millennium, January 1, 2000, I will depart for my field experience in Antarctica. I will arrive at Palmer Station located on the Antarctic Peninsula via the R/V LM Gould. The Palmer Long Term Ecological Research (Palmer/LTER) site is located at Palmer Station. It is one of only 21 long-term research sites around the globe. The Palmer/LTER is a very dynamic study site due largely to the annual advance and retreat of sea ice on the Antarctic marine ecosystem. Antarctic sea ice fluctuates from about 4 million square miles during the summer months to nearly 20 million square miles in the winter! This HUGE annual advance and decay of sea ice is a major controlling factor in ecological processes surrounding the Antarctic Peninsula. It effects everything from the growth of phytoplankton to the breeding success of sea birds and large sea mammals. For almost 20 years researchers have been investigating this interplay between the physical and biological environment. Their research is invaluable as it gives us a clearer picture of the ecological processes and interactions over long periods of time. For almost two decades researchers have gathered large data sets to help us understand trends and patterns within the Antarctic ecosystem. Imagine what stories will unfold after a century or more of data collection! Studying this unique environment is a big undertaking and there are many different groups which focus on various components. I will be responsible for several different tasks while in Antarctica. In the past few months, I have spent time with my principal investigator, Karen Baker, at the Scripps Institute of Oceanography in San Diego. While there I received training on the fluorometric techniques. These techniques basically measure the amount of chlorophyll in a given amount of water. Chlorophyll counts are crucial because they help tell the story of primary productivity in the Antarctic marine system. Specifically, I will be testing two different solid standards that are used for calibration in fluorometers at Palmer Station. These instruments must be routinely calibrated in order to insure accurate measurements.
In addition to the solid standard tests, I will also be conducting water
quality tests on the marine waters
surrounding Palmer Station. My students in El Paso, Texas, are involved in
testing the waters of the
Rio Grande River and there is interest to see how the two aquatic systems
are similar/different. Another
focus of my work will be to develop photographic catalogues and virtual
tours of my work at Palmer,
the research vessel LM Gould, penguin rookeries and more. These will then
be mounted on the TEA
and Palmer/LTER website. I am also planning to take a student designed
experiment with me in to the
field! Stay tuned for an update. Another thing I am interested in doing is
identifying and collecting
items from the Antarctic for a traveling educational "ice chest." This ice
chest will include Antarctic
artifacts, books, references, etc., to be shared among interested
schools.
