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.

Shown here is a photograph taken on October 20, 2023, of a wild Elkhorn coral colony in Buck Island Reef National Monument, St. Croix, VI, showing the effects of heat stress caused by elevated ocean temperatures. The heat stress causes “coral bleaching,” or the loss of nutrient-giving microscopic algae that normally live within corals.
