A seminar by Dr Erin Peck, Northeast Climate Adaptation Science Center, University of Massachusetts Amherst (USA).

Tidal wetlands maintain high biotic diversity and primary productivity; influence biogeochemical cycles as a critical junction between terrestrial and marine environments; and are considered some of the most valuable ecosystems on the planet.

Quantification and comparison of morphological and biogeochemical changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping these important habitats.

Dr Erin Peck will discuss the estimation of rates and drivers of sediment and blue carbon accumulation, which is made possible by analysis of sediment archives and comparison of histories of sediment accumulation between systems with spatiotemporally variable drivers. In particular, the Oregon margin provides an opportunity to compare a number of important drivers of centennial salt marsh morphologic change, including relative sea level rise, suspended sediment supply, basin area, bay morphology, and tectonics.
