From Fjord to Shelf: Drivers of Organic Carbon Transformation and Storage Across Connected Marine Sedimentary Systems

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract Continental shelf sediments play a key role in the global carbon cycle through the long‐term storage of organic carbon (OC). However, outside of a few continental shelves dominated by large rivers our understanding of the mechanisms that drive the remineralization, burial and storage of OC across these sedimentary systems is underdeveloped.

Effects of Temperature on Mercury Methylation and Demethylation in Boreal Wetland Soils

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Wetlands are critical sites for methylmercury (MeHg) production, a neurotoxin that bioaccumulates in organisms and biomagnifies in aquatic food webs. Net MeHg production in wetland soil depends on the balance between microbially mediated MeHg production and the degradation of MeHg through both microbial and abiotic pathways.

Greenhouse Gas Dynamics From Created Wetlands of New Brunswick and Nova Scotia (Canada)

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Beginning in the 17th century, Acadian settlers dyked and drained salt marshes along the Bay of Fundy in Eastern Canada, transforming them into agricultural fields. Over the last ∼50 years, impoundments were created by building dykes to contain freshwater.

Ecosystem‐Scale Methane Emissions From Peatlands of the Hudson Bay Lowlands

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Northern peatlands are important sources of methane (CH4) in the atmosphere. However, the magnitude of CH4 emissions and their response to environmental factors are poorly constrained within the Hudson Bay Lowlands (HBL), the largest contiguous peatland complex in North America. This study investigated seasonal (April–November) eddy covariance‐

Reducing Spatial Bias at Heterogeneous Sites: A Novel Eddy Covariance Filtering Approach Integrating Footprint Modeling and Remote Sensing

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Eddy covariance (EC) measurements of net ecosystem exchange (NEE) over sites with multiple land cover classes may suffer from significant uncertainty due to heterogeneity in biological source/sink distribution and flux footprint variation, masking the “true” signal of the target system.
