Acute cardiovascular changes following heat exposure during simulated shipboard firefighting
Abstract Like structural firefighting, shipboard firefighting requires extreme exertion. However, shipboard firefighting may be a unique cardiovascular stress as most sailors lack extensive firefighting experience and may complete significant work before reaching the fire scene.

From Surface to Depth: SWOT Altimetry and Glider Observations of a Cuddy in the Northeast Pacific
Abstract California Undercurrent Eddies (Cuddies) transport heat, salt, and biogeochemical properties from coastal regions to the open Northeast Pacific, but their three‐dimensional structure, lateral exchange mechanisms and complete life‐cycle are still not fully understood.

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

Green Hydrogen in Brazilian Media: Dominant Narratives and Missing Dimensions of the Energy Trilemma
ABSTRACT Media discourses help shape the visibility and legitimacy of energy transition pathways in the public sphere. This study examines how Brazilian mainstream newspapers framed green hydrogen and assesses the alignment of these narratives with the energy trilemma: energy security, environmental sustainability, and social accessibility. We analyzed
