Larval Transport Pathways Reveal Critical Habitat and Benefits of a Marine Protected Area to Fisheries

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

Flood Risk Communications Through Maps: Challenges, Perception Theories and Approaches

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flood risk communication is a core component of flood risk management, yet persistent challenges limit its effectiveness in supporting public understanding, preparedness and adaptive behaviour. Here, we examine flood risk maps as communication tools at the interface of scientific modelling, visual design, and human risk perception.

Sea level change in the Malaysian seas from multi-satellite altimeter data [PDF]

open access: yes, 2009
Seas from satellite altimetry data of the Topex, Jason-1, ERS-1, ERS-2 and Envisat missions. During the past two decades, satellite altimeter has provided its capability in measuring the global mean of sea level with precision better than 1 mm/year.

Characteristic Geometry of Keels in Arctic Sea Ice Ridges

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Deformation within and between sea ice floes creates pressure ridges, which compose a considerable volume fraction of the Arctic sea ice cover and complicate sea ice volume measurements. An important parameter for quantifying the ice volume contained in these deformation features is the keel shape.

Streamflow Elasticity to Precipitation Distribution and Potential Evapotranspiration Across South America

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Graphical abstract summarizing the modelling experiments used to quantify streamflow elasticity to changes and temporal redistribution of precipitation across South America, highlighting stronger effects of seasonal redistribution and larger responses in humid climates. ABSTRACT This study examines the sensitivity of mean, high and low streamflows (i.e.
