Research Integration - Coastal System Change at Fire Island, New York

In order to predict the future behavior of the Fire Island landscape as a whole, information from across research themes must be integrated.

Back-barrier and Estuarine - Coastal System Change at Fire Island, New York

Regional-scale modeling forecasts how atmospheric forcing and oceanographic circulation influence estuarine circulation and water levels, sediment transport, and wetland change.

Salmon River Mountains Legacy Mining Studies

The objective of this study is to characterize the regional impact of legacy mining in the context of framework geology for the Salmon Mountains in central Idaho. This objective is addressed through three interrelated tasks: 1) framework geology, 2) watershed biogeochemical processes, and 3) characterization of trace metals in colloids (fine particles suspended in water).

Predicting Future Beach Change - Coastal System Change at Fire Island, New York

Probabilistic models are used to predict future beach changes at Fire Island. These models, referred to as Bayesian networks, use statistics to estimate probabilities of future beach configurations based on existing observations. Bayesian networks are easily updated with new data or observations, making this approach ideal for use in coastal systems that experience rapid and frequent changes...

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

Given the unique challenges in quantifying the extensive, yet variable impacts of Hurricane Sandy at Fire Island, we used a time series of beach profile data at Fire Island, New York, to define a new contour-based morphologic change metric, the Beach Change Envelope (BCE).

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.

Oceanside Beaches and Dunes - Coastal System Change at Fire Island, New York

Oceanfront research at Fire Island, New York, is primarily focused on understanding the long- and short-term behavior of the ocean-facing terrestrial barrier island system, including human influences. The USGS has had ongoing research activities on Fire Island since the late 1990s, providing science to help inform management decisions. Recent efforts include monitoring the response to and...

Geology and Sediment Availability - Coastal System Change at Fire Island, New York

Sediment supply is a critical control on barrier island vulnerability and resilience over a variety of time scales (e.g., storms to sea level rise). Past work at Fire Island and elsewhere has demonstrated a link between inner shelf sediment availability and barrier island evolution over geologic and historical time scales. However, there have been few opportunities to explore nearshore...

Long-Term Change - Coastal System Change at Fire Island, New York

Long-term coastal change can occur over historical (10s to 100s years) and geological time scales (100s-1000s years). At Fire Island, the historical record of the position of the island goes back to the 1800s. Changes since then are quantified using historical maps, aerial photos, and modern coastal mapping techniques.
