Biophysical structure and particle dynamics of an algal bloom within a mesoscale eddy

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Mesoscale eddies create dynamically distinct environments where thermohaline fronts partition the biological and optical structure of the upper water column. How these fronts organize the vertical and lateral structure of spring blooms is a longstanding observational challenge, largely because the bloom environment evolves rapidly across ...

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 ...

Lensless Miniature Portable Fluorometer for Measurement of Chlorophyll and CDOM in Water Using Fluorescence Contact Imaging

IEEE Photonics Journal, 2014
We report on the design, fabrication, and verification of a proof-of-concept miniature fluorometer, which is designed to measure chlorophyll and colored dissolved organic matter (CDOM) concentration in aquatic environment.

Solid phase extraction of ocean dissolved organic matter with PPL cartridges: efficiency and selectivity

Frontiers in Marine Science, 2023
Our current knowledge of the chemical composition of ocean dissolved organic matter (DOM) is limited, mainly because of its extreme molecular diversity, low concentration of individual compounds and the elevated ionic strength of ocean waters.

Absorption‐Based Wavelength‐Resolved Hyperspectral Primary Productivity Algorithm for the Northern Gulf of Mexico

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The northern Gulf of Mexico (nGOM) is a region of high biological productivity largely influenced by the nutrient input from the Mississippi and Atchafalaya rivers. Prior studies utilizing bio‐optical algorithms to estimate primary production (PP) in this region have generally employed wavelength‐integrated models (WIM) involving attenuation ...

Influence of Chlorophyll and Colored Dissolved Organic Matter (CDOM) on Lake Reflectance Spectra: Implications for Measuring Lake Properties by Remote Sensing [PDF]

Lake and Reservoir Management, 2006
Abstract Light reflected from lake surfaces can convey much information about water quality, especially algal abundance, humic content, turbidity and suspended solids. Light reflectance from lakes is complicated, and detailed spectra are needed for analysis of controlling factors.

Tracing the transport of colored dissolved organic matter in water masses of the Southern Beaufort Sea: relationship with hydrographic characteristics [PDF]

Biogeosciences, 2012
Light absorption by colored dissolved organic matter (CDOM) [a_CDOM(λ)] plays an important role in the heat budget of the Arctic Ocean, contributing to the recent decline in sea ice, as well as in biogeochemical processes.

Regional landscape differences lead to contrasts in the strength of environmental sorting among crustacean zooplankton metacommunities

Oikos, Volume 2026, Issue 8, August 2026.
Processes underlying metacommunity structuring are important for understanding species tracking of environmental change at a landscape scale. Species' functional traits more closely reflect their ecological roles than taxonomy, therefore, adopting a functional approach allows us a better understanding of metacommunity structuring.

Benthic fluxes of dissolved organic nitrogen in the Lower St. Lawrence Estuary and implications for selective organic matter degradation [PDF]

, 2013
The distribution of dissolved organic nitrogen (DON) and carbon (DOC) in sediment porewaters was determined at nine locations along the St. Lawrence estuary and in the gulf of St. Lawrence. In a previous manuscript (Alkhatib et al., 2012a), we have shown
