The Digital Shoreline Analysis System (DSAS) version 6 is a standalone application that calculates shoreline or boundary change over time. The GIS of a user’s choice is used to prepare the data for DSAS.  Like previous versions, DSAS v.6 enables a user to calculate rate-of-change statistics from multiple historical shoreline positions.

DSAS generates transects that are cast perpendicular to the reference baseline to intersect shorelines at a user-specified spacing alongshore. Please note that the figure above illustrates the placement of both onshore and offshore baselines as examples. In DSAS v6.0 all baselines in a file must be placed either offshore or onshore, not combined.

On January 17-18, 2024, John Warner provided a two-day training for the COAWST (Coupled Ocean-Atmosphere-Waves-Sediment Transport) modeling system.

USGS scientists working on the Future Landscape Adaptation and Coastal Change (FLACC) project bring together information on coastal environments, processes, and climate drivers to evaluate where and when future changes along our Nation’s coast may occur and what they may look like.

Scientists at the USGS are installing sensors in Wellfleet MA, part of the Cape Cod National Seashore to evaluate the long-term and short-term chemical and geomorphic changes within wetlands.

As sea-level rise accelerates, vegetation transitions are increasingly observed and USGS scientists are busy assessing those changes. Shoreline at the Cape Cod National Seashore in Wellfleet, MA.

Time-series of number of seabeach amaranth observed in end-of-season surveys by NPS biologists. Shaded regions specify years where drought conditions persisted through the amaranth growing season. Vertical lines denote strong storms that occurred during the observation period.

Users can navigate the collection by clicking on the tiles on the cover page or the tabbed menu. With the Collection viewer, users can use a swipe tool to compare layers and click to see the values for each pixel. Users can also add other data to the viewer and bookmark any locations of interest.

The collection provides a motivation for the USGS coastal wetland research and individual web apps where users can browse each CONUS-wide data separately (relative tidal elevation, unvegetated-vegetated ratio, and aboveground biomass). It also provides a Collection viewer, where users can browse the CONUS-wide collection on the same map.
