Hidden subsurface suspended sediment export from Greenland's marine‐terminating glaciers

Abstract Runoff and calved ice volumes from the Greenland Ice Sheet are well constrained, but quantifying the associated suspended sediment flux remains challenging. Here we present near‐terminus observations from three glacierized fjords in southeast Greenland, combining full‐de...

Steric‐Setup Effects on US East Coast Sea‐Level Change

Abstract The extent to which coastal sea levels co‐vary with open‐ocean variability is explored through evaluation of a balanced dynamics framework relating sea level with pressure, density, and velocity along the continental shelf and slope seafloor. Using high‐resolution region...

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate chang...

Enceladus-like geochemistry fuels methanogenesis under extreme CO 2 limitation

Saturn’s icy moon Enceladus features chemical signatures consistent with an alkaline soda ocean with H 2 production via hydrothermal water-rock reactions. Chemolithoautotrophic methanogenesis is thermodynamically favorable under these conditions, but it is unknown whether CO 2 sc...

Climate mitigation contributes more to population persistence than evolutionary adaptation in a long-lived seabird

Evolutionary rescue–the process by which adaptive evolution prevents population extinction following environmental deterioration –is frequently proposed as a buffer against biodiversity loss under climate change, yet its capacity to alter future population trajectories is rarely...

A standardized field framework for integrated microbiological and geochemical sampling of deeply-sourced seeps across large-scale geological gradients

Accessing the deep subsurface biosphere remains a major challenge in Earth and planetary sciences. Drilling provides direct access but is costly, spatially restricted, and difficult to deploy at the scales required to investigate interactions between geological processes and micr...

Typifying tiny teeth: A standardized coding system to quantify morphological variation in fish teeth for comparative ecological, evolutionary, and functional morphological studies

Abstract Teeth play a crucial role in vertebrate ecology as one of the main interfaces between predators and their prey. As the most diverse vertebrates on the planet, and the dominant vertebrate consumers in nearly all aquatic ecosystems, fishes – and their teeth – thus play an...

Shipping noise may trigger valve closure responses in exploited scallop beds of the Gulf of St. Lawrence

Shipping noise is a pervasive form of underwater noise pollution, yet its effects on benthic invertebrates remain poorly integrated into spatial risk assessments. The Atlantic sea scallop (Placopecten magellanicus), a benthic bivalve supporting the world's largest wild pectinid f...

Year-round movement of emperor penguin colonies observed from space

Abstract Emperor penguins are threatened by climate change and their population is predicted to decline rapidly this century due to changes in Antarctic sea ice. Remote sensing is a key tool for monitoring emperor penguins but analysis has been restricted to spring/summer due to...

Socio-Environmental Characterization of Artisanal Fishers in the Lower Magdalena River Estuarine Zone: Implications for Water Governance and Monitoring Systems

Artisanal fisheries are fundamental to riverine socioecological systems, yet fishing communities remain underrepresented in environmental governance and decision-making. This gap constrains the incorporation of local knowledge into environmental decision-making and may reduce the...

Coupling of Pacific and Indian Ocean variability disrupted by 19th century volcanism

The stability of inter-basin coupling between the tropical Pacific and Indian Ocean remains uncertain. This study shows that past volcanism can temporarily weaken this relationship, but recent decoupling due to global warming is unprecedented.

Measuring Ocean Surface Waves

Abstract Propagating waves on the ocean surface can be represented as a stochastic process whose statistics are characterized by a spectrum. This paper reviews methods for measuring the wave spectrum and related quantities. Observations begin by sensing fluid dynamical properties...

High genetic connectivity and weak spatial structure in the ghost crab Ocypode stimpsoni (Ortmann, 1897) across Northeast Asia: insights from microsatellite and mtCO1 loci

The dataset includes allele-size microsatellite genotypes for Ocypode stimpsoni individuals (n = 167) collected from seven coastal localities across Northeast Asia, including South Korea, Japan, and Taiwan. These data were used to evaluate population genetic structure, genetic co...
