The study is the first to estimate salt-marsh vulnerability using the geological record of past losses in response to sea-level change.

An international team of scientists, led by former Rutgers-New Brunswick Professor Benjamin Horton—now acting chair and a professor at the Asian School of the Environment at Nanyang Technological University—found that rising sea levels in the past led to increased waterlogging of the salt marshes in the region, killing the vegetation that protects them from erosion. The study is based on data from 800 salt-marsh soil cores. Tidal marshes rank among Earth's most vulnerable ecosystems.
