Spatio-Temporal Statistical Models for Forecasting Climate Change Effects on Bird Distribution

Ecological indicators of climate change are needed to measure concurrent changes in ecological systems, inform management decisions, and forecast the consequences of climate change. We seek to develop robust bird-based, climate-change indicators using North American Breeding Bird Survey data.

Storm Impacts - Coastal System Change at Fire Island, New York

Fire Island is vulnerable to considerable storm activity year-round from both hurricanes and nor’easters. Storms are important drivers of coastal change in barrier island settings such as Fire Island. Larger storms carry sediment to the interior of the island via overwash, helping to create new habitat and build island resilience by adding back barrier width and interior elevation. Storms also...

Beach Change Envelope - Coastal System Change at Fire Island, New York

Beach Profiles - Coastal System Change at Fire Island, New York

As part of the assessment of beach and dune morphologic change associated with Hurricane Sandy and the continuing efforts to track post-Sandy recovery, differential global positioning system (DGPS) elevation data are collected along 15 shore-perpendicular profiles extending from just inland of the crest of dune to the low-tide swash zone.

Beach Recovery - Coastal System Change at Fire Island, New York

Alongshore features, such as the position of the dune crest and shoreline, are typically used to measure storm impacts and recovery. Impacts from Hurricane Sandy were so substantial to these features, however, that USGS researchers were provided a unique opportunity to develop new techniques to capture and monitor both storm impacts and recovery.
