Castle Lecture Series

The Coastal Anthropocene

This lecture is part of the monthly Castle Lecture Series hosted by the Smithsonian's Grand Challenges Consortia.

The Coastal Anthropocene
Dr. Patrick Megonigal
Deputy Director, Smithsonian Environmental Research Center
May 20, 2013
Noon–1pm ET

Humans have always settled near estuaries and coastal seas, and are highly concentrated near the coast to this day. Human activity has fundamentally changed the biology, geology, and hydrology of the coasts through the decline of some species and the introduction of other species, redistribution of sediments, nutrient enrichment and land reclamation. The scale of these impacts has grown to include planet-wide changes such as sea level rise. It is wise to recognize that the present options for managing coastal systems are constrained by past practices, just as future options depend on the decisions we make today.

Video of this talk will be posted at a later date.

The presentation will be webcast and archived on this page.
