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 […]
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 […]
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 […]
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 […]
This short (1 minute) movie describes the purpose of measuring water exchange in tidal creeks in the Plum Island system. Here is a view of the ADCP and water quality sampling from the air!
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 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!
With each 1m sediment core getting sectioned at 1 cm increments, we have lots and lots of sediment parties strewn around lab!
Rosie and Danielle push the boat out of Shad Creek in Plum Island close to low tide. A few more minute and we would have been stranded for a couple of hours until the tide came back in.
Abe got to visit the summer field crew at the Connecticut River boat dock. He was pretty happy about it.
