Coupled Dynamics of Wetlandscape Properties and Phytoplankton Bloom Magnitude and Extent in Lake Winnipeg

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Wetlandscapes—networks of hydrologically connected wetlands—can influence the transport and transformation of nutrients across watersheds. As climate change and human activity reshape wetland extent and connectivity, these landscape‐scale processes are being altered in ways that may intensify eutrophication in downstream lakes. We used Landsat‐

Fresh water influence on nutrient stoichiometry in a tropical estuary, southwest coast of India [PDF]

, 2008
Cochin backwaters, a micro tidal estuary, undergo a characteristic transformation from a river-dominated system during summer monsoon to a tide-dominant system during pre-monsoon season.

The metabolic regimes of 356 rivers in the United States [PDF]

, 2018
A national-scale quantification of metabolic energy flow in streams and rivers can improve understanding of the temporal dynamics of in-stream activity, links between energy cycling and ecosystem services, and the effects of human activities on aquatic ...

Analyzing Synthetic Stage‐Discharge Rating Curves and Riverine Flood Inundation Maps Derived From Global‐Scale Hydrologic and Hydraulic Modeling

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT Synthetic rating curves (SRCs) are often used to translate streamflow forecasts into flood inundation maps. Previous studies have investigated the development and errors in SRCs at local, regional, and continental scales. In this analysis, we used the latest global methodology and datasets to develop SRCs for use in flood inundation map ...

The water temperature characteristics of the Lena River at basin outlet in the summer period [PDF]

, 2016
The water temperature characteristics of the Lena River at basin outlet during the summer season (June–September) are considered. The analysis is based on long-term data series covering the period from the beginning of observation (1936) to the present ...

Urban heterogeneity drives dissolved organic matter sources, transport, and transformation from local to macro scales

Limnology and Oceanography, Volume 70, Issue 11, Page 3109-3126, November 2025.
Abstract Urbanization reshapes dissolved organic matter (DOM) sources, transport, and transformations through changes in vegetation, hydrology, and management of waste and water. Yet the impacts of urbanization on DOM are variable within and among cities.

Tracer Applications of Noble Gas Radionuclides in the Geosciences

, 2013
The noble gas radionuclides, including 81Kr (half-life = 229,000 yr), 85Kr (11 yr), and 39Ar (269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes.

Episodic Salinization of Midwestern and Northeastern US Rivers by Road Salt

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Freshwater salinization disrupts aquatic ecosystem processes such as organismal development, replenishment of dissolved oxygen, and geochemical cycling. A well‐documented but poorly understood signature of salinization to streams and rivers is “episodic salinization,” or short‐term pulses of salinity from extreme events.

How Spatial Resolutions Impact the Large‐Scale River Hydrodynamic Model Simulations: Analysis Focuses on Model Physics

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Large‐scale hydrodynamic models are vital for flood risk assessment and understanding the global water cycle; however, their results can include uncertainties related to spatial resolution. Few studies have evaluated hydrodynamic models across a range of spatial resolutions, with most focusing on a few variables (e.g., discharge) and often ...

Diatom-inferred salinity records from the Arctic Siverian margin: Implications for fluvial runoff patterns during the Holocene [PDF]

, 2003
Diatom assemblages were employed to study temporal changes of Siberian river runoff on the Laptev Sea shelf. Using a correlation between freshwater diatoms (%) in core-top sediments and summer surface water salinities from the inner Kara Sea, salinity ...
