Biogeochemistry

Biogeochemical control points of connectivity between a tidal creek and its floodplain

As global climates shift, coastal systems experience changes that alter function within the tidal zone. However, it remains uncertain how changes in tidal extent and magnitude will alter coastal biogeochemical cycling. We present high‐frequency data …

COMPASS-FME

The Coastal Observations, Mechanisms, and Predictions Across Systems and Scales - Field Measurements and Experiments project aims to understand how interactions among water, soils, sediments, and plants drive carbon and nutrient fluxes and transformations across the coastal interface

TROCAS

This project seeks to unravel the sequence of processes and sources of terrestrially-derived organic matter that culminate in the immense carbon dioxide outgassing to the atmosphere from tropical rivers worldwide.

Tree Methane

This project explores the mechanisms of a recently discovered phenomenon - the emission of methane and other greenhouse gases from trees. We use a range of field and laboratory techniques to understand, and ultimately predict the magnitude and drivers of tree methane emissions in upland and wetland forests near the coast.

Marked isotopic variability within and between the Amazon River and marine dissolved black carbon pools

Riverine dissolved organic carbon (DOC) contains charcoal byproducts, termed black carbon (BC). To determine the significance of BC as a sink of atmospheric CO2 and reconcile budgets, the sources and fate of this large, slow-cycling and elusive …
