Optimal horseshoe crab harvest policies via approximate dynamic programming Optimal horseshoe crab harvest policies via approximate dynamic programming

Approximate Dynamic Programming relies on forward simulation of the system, so two population projection models are used, one for crabs and one for red knots. The two models are linked: HSC abundance is a predictor variable in the REKN model. Other useful outputs are produced as well, such as predictions of future harvest.

Geospatial characterization of salt marshes in Chesapeake Bay Geospatial characterization of salt marshes in Chesapeake Bay

This data release contains coastal wetland synthesis products for Chesapeake Bay. Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, and tidal range are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological Survey has been...
