The "nutritional value" of glacial runoff is changing. Researchers found meltwater from retreating glaciers delivers sediment with lower concentrations of usable iron and manganese to coastal ecosystems. ❄️🧪 eos.org/articles/gla...
Glacier Runoff Becomes Less Nutritious as Glaciers Retreat - Eos
Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.

Wave-driven flows like rip currents disperse particulates seaward from the surfzone and create a turbid nearshore zone. Speiser et al., use Sentinel-2 imagery to reveal the drivers of turbid nearshore zone dynamics in north California 🌊

Moving people and equipment during fieldwork can be difficult during the best of times. For the MOSAiC team, inclement weather, polar night, and their location directly on the sea ice provided unique challenges for transportation. #FieldworkFriday

2/ But what drives the intrusions of warm water onto Antarctica’s continental shelf, where they can destabilise glaciers? A new study in @jgroceans.bsky.social led by Natalia Ribeiro @imos-aus.bsky.social uses a model to simulate how warm water gets into Vincennes Bay.

East Antarctic temperature, as simulated by the ACCESS-OM2-01 model. Colors show the ocean's bottom temperature on the continental shelf, and at 1,000 m depth north of the shelf break (defined by 1,000 m isobath, shown by black contour line) for the year of 2012. The green box highlights the location of Vincennes Bay and the dashed black line indicates the location of Wilkes Land. The study region in relation to the Antarctic continent (green box) and relevant ice shelf/glacier systems is displayed as an inset on the top left.

If meltwater forms deep in the ocean it can be supercooled and freeze into platelet ice crystals, which contribute to sea ice formation. Brett et al., find thick bands of platelet ice formed from Ice Shelf Water released by the Campbell Ice Tongue 🌊

Science fraud is on the rise, facilitated by for-profit, open-access journals (Richardson et al, 2025, PNAS). These same journals are accelerating author and reviewer burnout by profiting from quantity while neglecting quality. Choose society journals where reputation and community are everything!
