Off the Rails: Studies on Delaware Clapper Rail

Written on: May 18th, 2020 in Wetland Animals

Colloquially known as marsh hens, the Clapper Rail (Rallus crepitans) is a vocal inhabitant of saltmarshes across the eastern coast of the United States and down into the Caribbean. Many of the first in-depth observations of Clapper Rail occurred in the mid-Atlantic, and in Delaware, Brooke Meanley documented much of their ecology. The northern Clapper Rail populations, including Delaware, have been declining based on extensive survey work conducted by the Saltmarsh Habitat Avian Research Program (SHARP).

LiDAR Accuracy in Delaware’s Salt Marshes

Written on: March 6th, 2020 in Wetland Assessments

In tidal marshes, accurate representation of marsh elevation or height is critical for understanding sea-level rise, tidal inundation, and storm surge. Small changes in marsh elevation can significantly change the water movement (hydrology), plants (vegetation), and habitat. Our study aims to look at and correct a remote sensing method known as light detection and ranging (LiDAR), in order to provide accurate elevation data to scientists and coastal managers in Delaware.

Watching the Tide Come In: Environmental Thermography Meets Tidal Wetland Hydrology

Written on: May 18th, 2018 in Wetland Assessments

by Tom McKenna, Delaware Geological Survey, University of Delaware Working in tidal wetlands, we all know to watch the tide both for safety, sampling, and science reasons. But what do we really know about how tidal wetlands are inundated? The dynamics of the ebbing and flooding tide in deep (> 1 meter) tidal channels is […]

“Groundwater outcrops”: Wetlands associated with springs and seeps

Written on: December 12th, 2017 in Wetland Assessments

Guest Writer: Tom McKenna, University of Delaware Groundwater discharge areas are common hydrologic features in Delaware’s Piedmont Province, located in hilly northern New Castle County. Discharge occurs as springs or seeps. (A seep can be described as simply a spring with discharge through the very small openings between soil or sediment grains. In reality it […]
