Using sediment cores to trace the evolution of Jamaica Bay’s wetlands, a team of researchers found urbanization is weakening the shoreline and starving the marshes of vital mineral sediment, causing their gradual but dramatic erosion.
Scientists at Columbia’s Earth Institute are using simulations to test how well different methods protect coastal areas from hurricanes and sea level rise.
In a new study, Columbia researchers have mapped out a stew of discarded pharmaceuticals dissolved throughout the Hudson River. They say that in some places, levels may be high enough to affect aquatic life.
