Congratulations to the 2018 graduates! The Weston lab is especially proud of undergraduate students Olivia Cacciatore (grad school at University of Florida), Diana Lampasona (position with ESRI), and Mikala Jordan (grad school at the University of Utah), and graduate students Elise Rodriguez, Alec Davis, and Mary Zawatski (shown in picture during graduate ceremony), who all […]
Elise Rodriguez successfully defended her thesis “Land cover impacts on mineral sediment delivery and accretion rates in tidal wetlands” on April 20. Elise combined Pb-210 counting from cores taken in systems along the East Coast with an in-depth GIS land cover change analysis to evaluate how sediment delivery and accretion rates are linked. It’s an […]
Mary Zawatski successfully defended her thesis “Carbon Exchange and Sediment Deposition in a Heterogeneous New England Salt Marsh” today. Mary has compiled an amazing data-set over the last two years that required multiple trips to Plum Island to measure ecosystem gas exchange. This is also the first graduate defense in the Weston Lab and in the […]

After a pilot installation, we installed the full-scale sediment exclusion experiment in the Delaware River in summer 2017. At two tidal marsh sites in the Delaware (Dividing Creek and Dennis Creek), we installed 3 sediment exclusion plots and 3 control plots. Each plot consists of a surface elevation table (SET) and 4 marker horizon plots. […]
We continued our tidal creek import/export measurements during the 2017 field season. We’ve measured the tidal exchange of materials (water, sediment, carbon, nutrients) several times at high-elevation and low-elevation marsh sites, to understand if marsh geomorphology influences the exchange of these materials. Eric installs sampling equipment at low tide at the start of an import/export […]
We’ve put effort into understanding the verical marsh-atmosphere exchange of CO2 (through both chamber measurements and eddy covariance towers), and the later exchange of carbon through the import/export measurements, but we wanted to evaluate the vertical exchange of C between the aquatic system and the atmosphere. Mikala’s project this summer was to measure CO2 (and […]
We visited Plum Island for a winter sampling in March 2017. We got our wish: a frozen marsh! Chamber measurements with ice over the collars yielded very low measurements of CO2 change, but we did observe some respiration. We can call our research vessel an ‘icebreaker’ now! I’ve never needed to break through ice in […]
We visited our pilot sediment-exclusion plots in the Delaware River in November 2016. The plots had been installed in May 2016, and we weren’t sure how well they’d stand up after 6 months. We were also measuring surface elevation tables (SETs) installed at several locations at the field site. The field crew: Arielle, Maddee, Brian, […]
