Acclimation of Charophytes to Spectral Composition of Light at Limiting Irradiances

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Irradiance is regarded as a key factor determining the maximum colonization depth (Z0) of submerged macrophytes. However, the relevance of acclimation capabilities to spectral composition under such low‐light conditions remains poorly understood.

Remote sensing estimation of the concentration and sources of coloured dissolved organic matter based on MODIS: A case study of Erhai lake

Ecological Indicators, 2021
The use of satellite remote sensing to estimate coloured dissolved organic matter (CDOM) and identify its potential sources is important for monitoring lake water quality and implementing management strategies.

Carbon source and weather in coastal North Carolina

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The increasing frequency of extreme weather events, including tropical cyclones, is altering the delivery and quality of organic matter (OM) exported from landscapes to estuaries. However, the mechanisms regulating these shifts, especially during multi‐year climatic oscillations, remain poorly understood.

High photoreactivity of chromophoric dissolved organic matter derived from Ulva prolifera and Sargassum

Frontiers in Marine Science
The epipelagic macroalgae of Ulva prolifera and Sargassum are the primary contributors to widespread seaweed tides globally. Both ocean plants release large amounts of chromophoric dissolved organic matter (CDOM) into the surrounding seawater.

The Shrinking Caspian Sea: Eco‐Hydrological Responses to Human and Climate Pressures

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood.

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.

Spectral Absorption Properties of Colored Dissolved Organic Matter (CDOM) and Total Suspended Matter (TSM) of Inland Waters

, 2010
Spectral absorption properties of total suspended matter (TSM) and colored dissolved organic matter (CDOM) are important for the use of the bio-optical model to estimate water quality parameters.

The most oligotrophic subtropical zones of the global ocean: similarities and differences in terms of chlorophyll and yellow substance [PDF]

Biogeosciences, 2010
The cores of the subtropical anticyclonic gyres are characterized by their oligotrophic status and minimal chlorophyll concentration, compared to that of the whole ocean. These zones are unambiguously detected by space borne ocean color sensors thanks to

Great Slave Lake as a Key Modulator of Dissolved Organic Carbon Fluxes From Boreal Landscapes to the Mackenzie River

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Understanding dissolved organic carbon (DOC) fluxes in boreal freshwater systems is critical for constraining high‐latitude carbon budgets and anticipating climate‐driven changes. Here, we present a retrospective assessment (2000–2024) of DOC fluxes in the Upper Mackenzie River watershed, focusing on Great Slave Lake (GSL), a key hydrological ...
