Chronic disease outcome metadata from German observational studies – public availability and FAIR principles

Scientific Data, 2023
Metadata from epidemiological studies, including chronic disease outcome metadata (CDOM), are important to be findable to allow interpretability and reusability.

Hyperspectral Data and Machine Learning for Estimating CDOM, Chlorophyll a, Diatoms, Green Algae and Turbidity

International Journal of Environmental Research and Public Health, 2018
Inland waters are of great importance for scientists as well as authorities since they are essential ecosystems and well known for their biodiversity. When monitoring their respective water quality, in situ measurements of water quality parameters are ...

Drivers of Dissolved Organic Matter Quality and Concentration in a Mountainous Subarctic Watershed, Yukon, Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Northern permafrost regions contain vast frozen stores of organic carbon that are vulnerable to thaw and mobilization. While considerable attention has been paid to carbon export from large Arctic rivers, gaps remain in characterizing dissolved organic matter (DOM) quality and export in permafrost influenced catchments that contain a mosaic of

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.

On the Enumeration of Minimal Dominating Sets and Related Notions

, 2014
A dominating set $D$ in a graph is a subset of its vertex set such that each vertex is either in $D$ or has a neighbour in $D$. In this paper, we are interested in the enumeration of (inclusion-wise) minimal dominating sets in graphs, called the Dom-Enum

Machine Learning Regression Approaches for Colored Dissolved Organic Matter (CDOM) Retrieval with S2-MSI and S3-OLCI Simulated Data

Remote Sensing, 2018
The colored dissolved organic matter (CDOM) variable is the standard measure of humic substance in waters optics. CDOM is optically characterized by its spectral absorption coefficient, a C D O M at at reference wavelength (e.g., ≈ 440 nm).

A Phenoregion Approach to Understanding Chlorophyll‐a Seasonal Cycles and Interannual Variability in the South‐West Indian Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The South‐West Indian Ocean (SWIO) displays marked spatial variations in physical forcings, driving in turn distinct seasonal biogeochemical regimes. Mesoscale eddies in the Mozambique Channel drive large‐scale redistribution of nutrients and plankton, while eastern Madagascar waters are highly oligotrophic.

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 ...

The use of gliders for oceanographic science: the data processing gap [PDF]

, 2013
Autonomous gliders represent a step change in the way oceanographic data can be collected and as such they are increasingly seen as valuable tools in the oceanographer’s arsenal.

Phytoplankton Biomass and Growth Limitation During Fifty Years of Reduced Nutrient Loading in Shallow Lake Arresø

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT We examine phytoplankton development and limitation in the 3‐m deep, well‐mixed water column of hypereutrophic, alkaline Lake Arresø during 50 years of improved sewage treatment that has reduced phosphorus (P) and nitrogen (N) availability and phytoplankton biomass.
