Enhancing the Advanced Lake Biogeochemistry Model for Application to Thermokarst Lakes on Qinghai‐Tibet Plateau

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Thermokarst lakes on Qinghai‐Tibet Plateau (QTP) are significant sources of greenhouse gas emissions, yet the underlying governing processes remain poorly understood. This study refines the Advanced Lake Biogeochemistry Model (ALBM) to characterize the unique environmental and biogeochemical processes of QTP thermokarst lakes. Key improvements

Excitation-Dependent Fluorescence Quantum Yield for Freshwater Chromophoric Dissolved Organic Matter from Northern Russian Lakes

Journal of Spectroscopy, 2018
Advanced fluorescence analysis within the wide range of excitation wavelengths from 230 to 510 nm accompanied with chromatography was used to study natural chromophoric dissolved organic matter (CDOM) from three freshwater Karelian lakes.

Eddies in Seasonally Ice‐Covered Fjords of the Northern Canadian Arctic Archipelago

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract We present the first direct observations of cyclonic passing and standing eddies within landfast ice‐covered fjords where wind stress is unavailable to drive the eddies. Using a series of winter and spring 2025 in situ observations from the northern Canadian Arctic Archipelago, we identify three baroclinic eddies beneath the landfast ice cover.

“Dynamics of chromophoric dissolved organic matter in the Atlantic Ocean: unravelling province-dependent relationships, optical complexity, and environmental influences”

Frontiers in Marine Science
We report on the spatial distributions and optical characteristics of chromophoric dissolved organic matter (CDOM) in the sea surface microlayer (SML), subsurface seawater (SSW), and water column profiles down to 500 m across a range of Atlantic Ocean ...

Insights on the Optical Properties of Estuarine DOM - Hydrological and Biological Influences.

PLoS ONE, 2016
Dissolved organic matter (DOM) in estuaries derives from a diverse array of both allochthonous and autochthonous sources. In the estuarine system Ria de Aveiro (Portugal), the seasonality and the sources of the fraction of DOM that absorbs light (CDOM ...

Impact of Simulated Risk Factor Management on Cardiovascular Disease and Costs in Type 2 Diabetes Using the ABC Model

Diabetes, Obesity and Metabolism, Volume 28, Issue 7, Page 5670-5683, July 2026.
ABSTRACT Aims We evaluated the impact of scenario‐based multifactorial control on the 3‐year incidence of fatal/non‐fatal cardiovascular disease (CVD) and associated healthcare costs in Asian patients with type 2 diabetes (T2D). Materials and Methods We applied the validated ‘ABC’ model to simulate the 3‐year impact of attaining multiple treatment ...

Enhanced Solar Radiation Attenuation in the Arctic Shelf Driven by Warming‐Induced Terrestrial Inputs

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Arctic warming accelerates permafrost thaw and coastal erosion, increasing terrestrial material transport to the ocean. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data (2002–2023), we report a widespread increase in the diffuse attenuation coefficient Kd(490) across Arctic shelves since 2018, notably in the Laptev and Kara ...

The spectral characterization on chromophoric dissolved organic matter released from leaching of wetland plant litter in Poyang Lake under inundation

All Earth
Chromophoric dissolved organic matter (CDOM) leached from litter plays a key role in wetland biogeochemical cycling. However, the release patterns and driving mechanisms of CDOM from large lake wetland plant litter under inundation remain poorly ...

Elucidating the Reactivity and Fate of Dissolved Organic Matter in Groundwater Entering the Alaska Beaufort Sea Coast Using 14C Ramped Oxidation

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Supra‐permafrost groundwater (SPGW) is a significant but understudied source of dissolved organic matter (DOM) to Arctic coastal systems. We applied ramped pyrolysis/oxidation (RPO) with Δ14C and δ13C isotopic analysis to assess DOM reactivity and origin in SPGW, river, and lagoon waters along the Alaska Beaufort Sea coast.
