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.

Morphological Behavior - Coastal System Change at Fire Island, New York

Sand is constantly exchanged between beaches, dunes, and the submerged shoreface, which includes the nearshore sand bar system. We use specialized vessels and equipment to understand the feedbacks between nearshore morphology changes and coastal change to improve predictions of future impacts.

The nearshore is the submerged portion of the shoreface between the inner shelf and the shoreline and includes the surf zone, where waves break. Along with beaches and dunes, nearshore morphology and geology adjusts to changes in waves, sediment supply, human alterations, and sea level rise. By measuring nearshore morphologic and geologic variations, we can understand how quickly beaches and...
