A semi‐analytical Bayesian estimate retrieval algorithm for the inversion of remote‐sensing reflectance in optically deep and shallow waters

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract The inverse problem in remote sensing of aquatic environment consists in retrieving optically significant constituents (OSCs) from a spectral measurement of the remote sensing reflectance (Rrs).Optically significant constituent includes chlorophyll a concentration (Chl a), a proxy of phytoplankton biomass, absorption of colored detrital matter

Selective accumulation of dissolved organic matter in the sea surface microlayer: integrated multi-spectral CDOM and FDOM characterization and a novel FDOM/CDOM index at a Mediterranean coastal site [PDF]

Biogeosciences
The aims of this work are: (i) To understand potential transformations and dynamics within the broad chromophoric dissolved organic matter (CDOM) pool in the sea surface microlayer (SML) and the underlying water (ULW) at a Mediterranean coastal site ...

The Contribution of Methane Photoproduction to the Oceanic Methane Paradox

Geophysical Research Letters, 2020
Although methanogenesis is considered a strictly anaerobic process, oxygen‐replete surface open‐ocean waters are usually supersaturated with methane (CH4), a phenomenon termed the oceanic methane paradox.

Land Cover and Hydrology Regulate Riverine Carbon Emissions From Subarctic Catchments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Streams transport carbon (C) and nutrients across the terrestrial‐aquatic interface and are significant sources of methane (CH4) and carbon dioxide (CO2) to the atmosphere. Climate‐induced changes in vegetation and hydrology increase the export of dissolved organic carbon (DOC) from terrestrial to aquatic ecosystems, but the impact of these ...

The role of wind and buoyancy forcing on mixed layer depths and productivity on the Chatham Rise from ocean glider and ship‐based observations

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1350-1370, December 2025.
ABSTRACT The Subtropical Front (STF) and associated biological productivity are topographically locked to the Chatham Rise. Year‐to‐year differences of upper ocean dynamics and associated responses of phytoplankton are valuable for understanding variability in fisheries biomass as well as providing new knowledge of environmental condition for potential

The impact of high rainfall events on the submesoscale salinity field in a coastal sea: Greater Cook Strait, New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 4, Page 735-761, December 2025.
ABSTRACT River inflow into the coastal oceanic environment can result in low salinity submesoscale features (LSMFs). The enhanced water column stability sustained within these coherent structures affects local biological productivity. With‐event and seasonal variability of LSMFs were investigated in a coastal sea — Greater Cook Strait — that is ...

Predicting Dissolved Black Carbon Concentration From Chromophoric Dissolved Organic Matter Along the Land‐Ocean Continuum

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Dissolved black carbon (DBC) plays a key role in global carbon cycle and pollutant transport. However, the time‐consuming and labor‐intensive chemical analysis limits its spatiotemporal resolution. Here, we developed models to predict DBC from chromophoric dissolved organic matter (CDOM) measurements across the land‐to‐ocean continuum.

Possible Effect of Climate Change on Surface-Water Photochemistry: A Model Assessment of the Impact of Browning on the Photodegradation of Pollutants in Lakes during Summer Stratification. Epilimnion vs. Whole-Lake Phototransformation

Molecules, 2020
Water browning in lakes (progressive increase of the content of chromophoric dissolved organic matter, CDOM) has the potential to deeply alter the photodegradation kinetics of pollutants during summer stratification.

Applications of QSPR and Machine Learning in Molecular Photonics

Advanced Optical Materials, Volume 13, Issue 33, November 25, 2025.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides
