New evidence from New Zealand suggests that calcium carbonate dissolution occurs not just over millennial timescales, but over annual and decadal ones too.

A satellite view of a portion of Earth shows the planet’s curved horizon at the top of the image. Green and brown landmasses are cut by two large, blue, winding rivers that empty into the ocean in the foreground. Clouds are visible on the edges of the image.

New River Chemistry Insights May Boost Coastal Ocean Modeling

by Sarah Stanley 9 January 20269 January 2026

By more realistically accounting for river inputs, researchers reduced overestimation of the amount of carbon dioxide absorbed by coastal waters.

A backward C-shaped swirl of milky blues and greens appears against a deep blue background. In the foreground, toward the edges of the image, clouds appear as white patches.

Wintertime Spike in Oceanic Iron Levels Detected near Hawaii

by Sarah Stanley 11 December 202511 December 2025

Seasonal rainfall and runoff of sediments from the Hawaiian Islands could be responsible for the previously undetected peak.

The planet Venus appears as a circular shape against a black background, with the right side sharply defined but the far left side fading into shadow. White, gray, and light orange swirling shapes cover the surface, appearing whiter, more linear, and more solid at the top and bottom of the circle but patchier toward the middle, with more patches of gray and light orange.

Key Driver of Extreme Winds on Venus Identified

A new study suggests that a once-daily atmospheric tidal cycle may be a bigger driver of rapid Venusian winds than previously thought.

Three images of the Jovian moon Io show different distributions of colors. The far left image has a spot of red and yellow at bottom left, and the other two images each have a spot of red and yellow in the top half.
