Overview

NCALM Project. PI: Paul Bierman, University of Vermont. The survey area consisted of two polygons: 1) over a portion of the Potomac River in Washington D.C. enclosing 60 square km; and 2) over a portion of the Susquehanna River in Pennsylvania enclosing 23 square km. The Susquehanna survey took place on January 9, 2005 and the Potomac survey took place on January 11, 2005.
