October Import/Export

We conducted tidal creek import and export measurements in mid October on the four sites we’ve been working on during 2016.  Daylight is in somewhat shorter supply this time of year, though the tides still take about 12 hours.  So we had to get out to the sites while it was still dark, work through […]

Early fall sampling 

We took a quick trip to Plum Island for an early fall CO2 gas flux measurement.     Brian, Mary, and Alec are measuring CO2 exchange between the marsh and the atmosphere. This work will be compared to the gas flux measurements made by the eddy covariance tower shown in the background, and allo is to […]

Plum Island Sampling

Our last summer sampling in Plum Island! We’re doing tidal creek import/export on 4 creeks, a water-column production and respiration experiment, marsh CO2 gas flux measurements, and helping out with the late summer metabolism transects (ramming). We’ll be back in October.   Mary and Brian measuring marsh CO2 exchange at various light levels.     Olivia and […]

Maine Sampling Trip

We visited tidal wetlands in the Kennebec River in coastal Maine as part of our survey of wetland accretion rates along the East Coast of the U.S.  We collected 10 deep cores, along with above- and below-ground biomass and RTK-GPS data. The trip was very successful, and it was an adventure. We gambled on getting […]

NSF Sediment Project Funded

Tidal marshes are productive ecosystems that provide key services to society such as carbon sequestration, storm surge buffering, and water-quality mitigation. The long-term stability of coastal wetlands is explained by interactions between sea level, plant growth, sediment supply, and wetland accretion, but coastal wetland stability is threatened by land use change and accelerating rates of […]

We got the drone!

We acquired a drone to facilitate aerial photography and change over time analysis of the Plum Island Ecosystem research site. It’s also a lot of fun to fly!
