Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

Improving Colored Dissolved Organic Matter (CDOM) Retrievals by Sentinel2-MSI Data through a Total Suspended Matter (TSM)-Driven Classification: The Case of Pertusillo Lake (Southern Italy)

Remote Sensing, 2023
Colored dissolved organic matter (CDOM) is a significant constituent of aquatic systems and biogeochemical cycles. Satellite CDOM retrievals are challenging in inland waters, due to overlapped absorption properties of bio-optical parameters, like Total ...

Ultraviolet radiation lowers upper thermal limits in marine diatoms

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Escalating ultraviolet radiation (UVR) and ocean warming are expected to interactively shape phytoplankton performance, yet their combined effects on diatom thermal plasticity remain poorly resolved. We quantified how UVR alters growth‐based thermal performance curves in three model marine diatoms grown across species‐specific temperature ...

Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...

Estimation of Chromophpric Dissolved Organic Matter Concentration in Erhai Lake Using the Quasi-Analytical Algorithm From Sentinel-3 Satellite Data

IEEE Access
Chromophoric dissolved organic matter (CDOM) is a crucial component of aquatic environments. Accurately quantifying the content of CDOM is essential for supporting lake water quality monitoring and management.

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

Limnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ), and beam ...

Parameterization of the light absorption properties of chromophoric dissolved organic matter in the Baltic Sea and Pomeranian lakes [PDF]

Ocean Science, 2016
This study presents three alternative models for estimating the absorption properties of chromophoric dissolved organic matter aCDOM(λ). For this analysis we used a database containing 556 absorption spectra measured in 2006–2009 in different regions of ...

Organic Matter Dynamics and Biogeochemical Signatures in Lakes From the Prairies to Tundra in Western Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Climate‐driven poleward shifts of terrestrial ecosystems are expected to alter organic matter inputs and biogeochemical processes in northern lakes. In regions lacking long‐term observations, latitudinal gradients provide valuable space‐for‐time substitutions for predicting these changes.

An explanation of the spectral variation in freshwater CDOM fluorescence [PDF]

Limnology and Oceanography, 1992
The variation of freshwater chromophoric (or colored) dissolved organic matter (CDOM) fluorescence with respect to sample pH was examined. Trends from previous studies are supported by results obtained from fluorescence spectra collected during sample titration.
