Collection Overview: NCALM Seed. PI: Brendan P. Murphy, The University of Texas at Austin. The survey area consisted of a 46 square kilometer irregular polygon on the island of Hawaii covering two distinct watersheds on the Kohala Peninsula. The data were collected to quantify the role of spatially variable climate in bedrock fluvial incision on the Kohala Peninsula. Repeated efforts were made to survey this area over an 8-day span. Unfortunately the ever-present cloud cover on the wet side prevented the completion of the survey. The survey attempts took placed from February 5, 2013 through February 12, 2013.Publications associated with this dataset can be found at NCALM's Data Tracking Center
