| Notes | What forces cause salt marshes to grow or shrink? This file gives data intended to help answer this question. “The dataset is a layer file created in ArcGIS Pro 2.2. The dataset includes digitized outlines of the seaward edges of five Oregon salt marshes (Nehalem, Netarts, Salmon, Alsea, and Coquille). These are roughly decadal from 1939 to 2018 and were hand-digitized using historical aerial photography (1939 to the late 1990s) scanned at the University of Oregon’s Map & Aerial Photography Library and aerial imagery downloaded from the Oregon Statewide Imagery Program (https://www.oregon.gov/geo/Pages/imagery_data.aspx)” (from the Abstract). Among the factors considered were the history of logging and the Pacific Decadal Oscillation. It is hoped that results will suggest future changes in marshes under a different climate and different land use practices. |
