Given this increasing need to forecast sea-level rise effects on barrier islands in the near and long terms, we are developing Bayesian networks to evaluate and to forecast the cascading effects of sea-level rise on shoreline change, barrier island state, and piping plover habitat availability.

The purpose of this survey was to acquire high-resolution, high-sensitivity aeromagnetic data over an area in northeast and north-central North Dakota and assess the area for anomalies and magnetic features pertaining to the local geology. To achieve this purpose, the survey area was systematically traversed by an aircraft carrying geophysical instruments along parallel flight lines (traverses) spaced 0.25 miles (400 meters) apart in an east-west alignment.
