New Evidence of MnO x -Mediated Pb Sequestration by Estuarine Biofilms in a Sediment–Water Microcosm

Abstract Intertidal biofilms experience recurring Pb exposure due to pollutant accumulation and sediment remobilization, and yet the sources supplying Pb to biofilms and mechanisms governing its uptake remain ambiguous. Using biofilms from Sundarbans as a globally relevant model,...

Marine Heat Waves and Cold Spells – Multiple Analysis/Definitions (MHW-MAD): A Multi-Definition Global Marine Heatwave Database from Satellite Sea Surface Temperature Data

Marine heatwaves (MHWs) are prolonged anomalies of warm sea surface temperature (SST) that can disrupt marine ecosystems, physical climate processes, and human coastal activities. MHW definitions vary due to different stakeholders requirements, such as ecological scientists and c...

Unprecedented Open‐Ocean Polynya in Breid Bay, East Antarctica in Winter 2024

Abstract We document an unprecedented winter open‐ocean polynya in the Breid Bay, on 4 August 2024, attaining a maximum area of 89,121 km 2 . Prior to opening, sea‐ice concentration declined from ∼96% in early July to below 25% by 30 July 2024, indicating substantial precondition...

Observational and numerical assessment of meteorological characteristics and climate variabilities over the Antarctic Peninsula in recent decades

Abstract The Antarctic Peninsula (AP) exhibits pronounced spatial variability in recent climate trends, with contrasting temperature changes between the West Antarctic Peninsula (WAP) and East Antarctic Peninsula (EAP). This study provides an observational and numerical assessmen...
