Shapefiles and Historical Aerial Photographs, Little Missouri River, 1995

5 aerial photographs were taken along the Little Missouri River in 1995. All images were geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). Both the flood plain and active channel of the river were delineated on the 1995 digital orthophoto quadrangles and overlaid on rectified photos. ArcGIS was used to draw the polygons that delineat...

Modified Herring Trawl Fish Catch Data, Gulf of Alaska Fjords, 2004-2011

This dataset contains catch data from trawls at the sampling stations. We deployed a modified herring trawl in coastal waters within glacier fjords of Alaska. Sampling stations in each fjord were chosen randomly from a 2.5 x 2.5 km grid overlaid on navigable waters in the fjord. The number of stations in each fjord was chosen to achieve a sampling frequency of about 1 sample per 15 km^2, and...
