Freshwater tidal marshes are globally rare, yet productive and significant habitats. Along the Hudson River, these ecosystems have been impacted by climate change stressors, particularly the effects of increased storms, including Tropical Storms Irene and Lee in 2011 and Hurricane Sandy in 2012. The Hudson River National Estuarine Research Reserve (HRNERR) has established a series of permanent vegetation transects in the marshes to document storm surge impacts to vegetation density and marsh elevation. By participating in this internship, you will learn to identify and quantify emergent marsh and submerged aquatic vegetation (SAV). Other internship duties include sampling Surface Elevation Tables (SETs), maintaining a tide station, assisting with elevation surveys, river water sampling (from shore or boat), assisting with laboratory processing of samples (filtering and weighing), calibrating instruments, and acid washing sample bottles.
