GRAIN: Mapping the World's Irrigation Canals and Why It Matters for Water, Food, and Climate

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The engineered channels that carry water from large dams and rivers to agricultural fields, known as irrigation canals, are the link between source (lakes and reservoirs) and sink (farmlands). These canals make cultivation of crops possible across millions of hectares of land.

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Water mass dynamics drive nitrogen fixation rates and diazotroph community composition in the coastal ocean

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Although significant N2 fixation rates (NFRs) have been observed throughout mid‐Atlantic coastal waters, studies have been limited in their temporal coverage, and the methods used to detect nitrogen fixers (diazotrophs) and their findings have varied.

Thermal Regime Dynamics in a Karst Watershed Influenced by Groundwater and Urbanization

Hydrological Processes, Volume 40, Issue 9, September 2026.
This study investigates how groundwater and urban development shape stream temperature patterns in the karstic Spring Creek watershed of central Pennsylvania, USA. Using high‐resolution monitoring, we found that groundwater inputs buffer temperature in some streams, while urbanised sub‐catchments experience extreme thermal surges due to heated runoff ...

Spatial and temporal patterns of bottom water euxinia in shallow areas of the southwestern Baltic Sea

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Sediments in productive coastal regions are hotspots of hydrogen sulfide (H2S) production through microbial sulfate reduction. Under anoxic seafloor conditions, H2S can escape the sediment and accumulate in bottom waters, where elevated concentrations render the benthic environment toxic, posing ecological and economic risks.

Biophysical structure and particle dynamics of an algal bloom within a mesoscale eddy

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Mesoscale eddies create dynamically distinct environments where thermohaline fronts partition the biological and optical structure of the upper water column. How these fronts organize the vertical and lateral structure of spring blooms is a longstanding observational challenge, largely because the bloom environment evolves rapidly across ...

Predicting Minnesota Lake Ice Phenology With Deep Learning, Explainable Methods, and a Physically Based Benchmark, 1980–2018

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Globally, lakes are losing ice cover, but our understanding of the rates and variability of change are biased toward few lakes with long‐term records. Recent works have used remote sensing and predictive modeling to supplement the observational record, but these approaches produce large errors when estimating ice phenology for individual lakes.

Anatomy of Interannual to Decadal Sea Level Changes in the GECCO3 Ocean Synthesis

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The GECCO3 synthesis is used to infer a dynamically consistent decomposition of sea level changes (variability and trends) on interannual to decadal time scales. Over most parts of the global ocean equatorward of 60° latitude, sea level variability and trends can be explained almost completely by the upper ocean (above 2,000 m) steric ...

Making Flood Inundation Mapping (FIM) Work for Multiple Users: Improving the Design of FIM for Decision Support

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Visualizing and communicating flood inundation depth and extent can be valuable for informing decisions related to flood preparedness and disaster response. In the United States, several different types of flood inundation mapping (FIM) exist and a new National Water Model (NWM) FIM product is being rolled out across the country (expected to ...
