Seasonal Estimates of Nutrient Loading, Sources, and Impacts on Water Availability in Streams Across the Conterminous United States, 2000–2020

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Excess riverine nutrients can limit water availability for humans and ecosystems. Nutrient monitoring on individual stream reaches provides important information about current and past conditions, yet most river reaches are unmonitored. Additionally, monitored data integrate effects of upstream sources, sinks, and pathways by which nutrients ...

Chironomids as Indicators of Biodiversity and Isolation Patterns in a Balkan Karst Biodiversity Hotspot

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Our research aimed to assess the beta diversity of Chironomidae (Diptera) and faunal connections across springs, streams, and rivers within the Skadar Lake basin, a Mediterranean biodiversity hotspot, using DNA barcoding. Location Skadar Lake basin—a Mediterranean biodiversity hotspot. Methods We analysed mitochondrial cytochrome c oxidase

Efficient Weather Routing Method in Coastal and Island-Rich Waters Guided by Ship Trajectory Big Data

Journal of Marine Science and Engineering
Weather routing is a critical guarantee for the safe and economical navigation of ships. Existing methods for weather routing still face challenges in selecting the appropriate planning granularity.

Stage‐Specific Indicators of Northern Yellowtail Rockfish (Sebastes flavidus) Recruitment in the California Current Ecosystem

Fisheries Oceanography, Volume 35, Issue 4, Page 630-649, July 2026.
ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Investigating the Impact of Spatiotemporal Variations in Water Surface Optical Properties on Satellite-Derived Bathymetry Estimates in the Eastern Mediterranean

Remote Sensing
Bathymetric data are crucial for benthic monitoring in coastal areas but are traditionally obtained through costly and geographically limited acoustic methods.

Long‐Lived Anticyclonic Eddies Facilitate Convection in the Greenland Sea Over Multiple Consecutive Winters

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Wintertime open‐ocean convection is a key process in renewing deep water; however, the processes that promote convection on local scale remain poorly understood. We investigate the role of long‐lived anticyclonic eddies in facilitating deep convection in the Greenland Sea using a new model simulation and observations.

Seasonal Prediction Skill Contrasts of Subtropical North Atlantic Sea Surface Temperature Anomalies Under Different AMV Phases

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Atlantic multidecadal variability (AMV) exerts profound climatic influences on both local and remote regions. Recent studies show that AMV can significantly modulate the El Niño–Southern Oscillation (ENSO) and its teleconnections. However, few studies have examined AMV impacts on seasonal prediction skill.

The Lifecycle of Tracer Variance in the North Atlantic

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Oceanic tracer distributions are shaped by turbulent mixing, which may be understood via a tracer variance budget. There is a tracer variance lifecycle: variance production by turbulent flows stirring large‐scale gradients, redistribution by currents, and variance dissipation by molecular diffusion.
