A coupled geochemical and biogeochemical approach to characterize the bioreactivity of dissolved organic matter from a headwater stream [PDF]

, 2014
The bioreactivity or susceptibility of dissolved organic matter (DOM) to microbial degradation in streams and rivers is of critical importance to global change studies, but a comprehensive understanding of DOM bioreactivity has been elusive due, in part,

Diagnosing coastal processes using machine learning and ocean buoyancy gliders

Limnology and Oceanography, Volume 70, Issue S1, Page S150-S164, July 2025.
Abstract Ocean buoyancy gliders provide a comprehensive view of the water column, offering more than simply a snapshot of a single moment in time or space. In this study, we applied the established machine learning method, k‐means clustering, to a glider dataset collected in the summer of 2015 in the northern Gulf of Mexico.

Loadings of dissolved organic matter and nutrients from the Neva River into the Gulf of Finland - Biogeochemical composition and spatial distribution within the salinity gradient [PDF]

, 2016
We studied the loadings of dissolved organic matter (DOM) and nutrients from the Neva River into the Eastern Gulf of Finland, as well as their distribution within the salinity gradient.

Forecasting climate and human alterations to coastal and estuarine dissolved organic matter

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 265-286, June 2025.
Abstract River networks serve as conduits for dissolved organic matter (DOM) and carbon (DOC) from inland to coastal waters. Human activities and climate change are altering DOM sources, causing hydrological and biogeochemical shifts that impact DOC concentrations and changing the transport and transformation of DOM and DOC. Here, we synthesize current

Mesoscale and submesoscale variability of organic matter in island-induced eddies across their life cycle: implications for the biological carbon pump

Frontiers in Marine Science
The Canary Islands region exhibits intense mesoscale activity, with eddies generated south the islands by perturbations of the Canary Current. After detachment, these eddies drift southwestward along the Canary Eddy Corridor (CEC), exporting their ...

Chemodiversity of dissolved organic matter in the Amazon Basin [PDF]

, 2016
Regions in the Amazon Basin have been associated with specific biogeochemical processes, but a detailed chemical classification of the abundant and ubiquitous dissolved organic matter (DOM), beyond specific indicator compounds and bulk measurements, has ...

Kinetics of superoxide reactions with dissolved organic matter in tropical Atlantic surface waters near Cape Verde (TENATSO) [PDF]

, 2010
The decay kinetics of superoxide (O2−) reacting with organic matter was examined in oligotrophic waters at, and nearby, the TENATSO ocean observatory adjacent to the Cape Verde archipelago.

Photooxidation removes biologically recalcitrant dissolved organic carbon released by the macroalga Sargassum natans

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 349-359, June 2025.
Abstract Macroalgae are important primary producers in the coastal ocean, and they release a large fraction of their net primary production as dissolved organic carbon (DOC). It is assumed that much of this DOC is recalcitrant and results in the sequestration of large amounts of carbon.

Light attenuation characteristics of glacially-fed lakes [PDF]

, 2014
Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic of these changes.
