Streams Geo-Morphology



In 1994, 16 stream transects were established in the McMurdo Dry Valleys of Antarctica 63 beginning a long term data set characterizing microbial communities and channel geometry. The 64 transects were established to record microbial mat dynamics and stream geomorphology. To accomplish this, the transects were surveyed for points of interest outside and inside the stream channel. Beginning in 2010 the microbial surveys received ground based LiDAR support. This allowed for greater resolution in mapping and analyzing stream morphology than traditional surveying methods. Using surveyed microbial mats as an indicator of a location in time, a history of channel elevations was created for 7 transects.  Here, you will find the massive long term data for the geomorphology of seven of the streams, along with detailed references to the methodology and results and other findings published in Steven Crisp thesis dissertation.
