Marsh Sediment Deposition Results & Data

With the help of high school and middle school students, Mass Audubon’s Salt Marsh Science Project is able to measure the vertical sediment deposition (gradual pile up of additional layers of sediment) on salt marshes across the North Shore using marker horizons. After one year or more, we go back and measure the amount of sediment accumulated on top of the marker.

Sedimento de pantano

Con la ayuda de los estudiantes de secundaria y preparatoria, el Proyecto de Ciencias del Pantano de Sal de Mass Audubon puede medir la deposición vertical de sedimentos (acumulación gradual de capas adicionales de sedimentos) en las marismas a través de la costa norte. Después de 1 año o más, regresamos y medimos la cantidad de sedimento acumulado en la parte superior del marcador.

With the help of participating students, we have been collecting data on salt marsh sediment accumulation as it relates to coastal Massachusetts since 2013. Please note that not all sites are monitored each year—the date range indicates the start date and the most recent year data was collected. 

→ You can also download the full data set as an Excel file, and then use the bottom tabs in the Excel file to look at each site.
