Glacial Meltwater Promotes Biological Productivity and Subsequent Dissolved Organic Carbon Accumulation in the Eastern Ross Sea: Evidence From the Austral Summer of 2023

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract The Ross Sea, a critical region for global carbon cycling, receives increasing glacial meltwater from West Antarctica, yet the impact on regional carbon cycling remains poorly understood. A key uncertainty is how this meltwater influences dissolved organic matter (DOM), particularly in the historically inaccessible eastern Ross Sea. This study

Short‐Term Estuarine Phytoplankton Dynamics in Response to Hurricanes Along the Gulf Coast of America: A Variational Autoencoder (VAE) Approach With Satellite and Bio‐Optical Observations

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Hurricanes drive diverse estuarine phytoplankton responses and can trigger cascading ecological and physicochemical impacts. Capturing these short‐term dynamics requires high spatiotemporal resolution. Here, we applied a globally‐applicable coastal ocean color algorithm, Variational Autoencoder (VAE), to Sentinel‐2 MSI imagery for chlorophyll ...

Delineating bio-optical characteristics to enhance spatial-based quantification of CDOM in clear to turbid waters

International Journal of Applied Earth Observations and Geoinformation
Accurate remote sensing estimates of inland water colored dissolved organic matter (CDOM) are dramatically challenged by the dynamics of bio-optical characteristics, in which water biochemical driving mechanisms are particularly complex and highly ...

CDOM Sources and Photobleaching Control Quantum Yields for Oceanic DMS Photolysis

Environmental Science & Technology, 2016
Photolysis is a major removal pathway for the biogenic gas dimethylsulfide (DMS) in the surface ocean. Here we tested the hypothesis that apparent quantum yields (AQY) for DMS photolysis varied according to the quantity and quality of its photosensitizers, chiefly chromophoric dissolved organic matter (CDOM) and nitrate.

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 ...

Assessing chromophoric dissolved organic matter (CDOM) distribution, stocks, and fluxes in Apalachicola Bay using combined field, VIIRS ocean color, and model observations

, 2017
Understanding the role of estuarine-carbon fluxes is essential to improve estimates of the global carbon budget. Dissolved organic matter (DOM) plays an important role in aquatic carbon cycling.

Processing BGC-Argo CDOM concentration at the DAC level [PDF]

, 2017
In the open ocean, Colored Dissolved Organic Matter (CDOM) is the fraction of the total Dissolved Organic Matter (DOM), composed by a mixture of chemically complex algal degradation products that interact with light. CDOM absorbs solar radiation in the UV and visible ranges (Bricaud et al., 1981) and, if illuminated, re-emits light as fluorescence (i.e.
