Jeff Patriarche, graduate student, will present "Phytoplankton dynamics in the Taylor Valley, Antarctica" as part of the LRES Seminar Series in 346 Leon Johnson Hall.
The McMurdo Dry Valleys (MDV) comprise the largest relatively ice-free region on the continent of Antarctica. Do to the extreme temperatures, strong winds, low precipitation, and long periods of complete darkness this is an area where life is reaching its environmental limits. Nestled within the Taylor Valley (of the MDV) are several perennially frozen lakes which have been the focus of intense ecological research for over 40 years. These isolated lakes contain microbial ecosystems that are driven by the primary productivity of photosynthetic algae. For the last 10 years the use of a submersible spectrofluorometer has provided a record of functional algal group community dynamics during the spring and summer months when logistical constraints on data collection are at a minimum. This seminar will highlight these phytoplankton community dynamics, as well as introduce key insights gained from an autonomous lake profiling system.
