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.
As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor glacial meltwater stream attributes of the region. Optical topographic surveys were performed to produce a layout of the area studied.
