Atmospheric oxygen constraints revise Southern Ocean productivity estimates
This research indicates that atmospheric oxygen measurements can constrain Southern Ocean net primary production and show that many Earth system models underestimate productivity and bias air-sea carbon dioxide exchange.

Australia reefs face different prickly population patterns
This research indicates that crown-of-thorns starfish and long-spined sea urchins create different reef problems, and that spatially structured prevention may be more efficient and cost effective than reactive control.

Hydrology controlled nitrate cycling in a tidal freshwater river
This research indicates that discharge and residence time were the main controls on nitrate retention and processing in a tidal freshwater zone, with internal nitrate cycling strongly influencing nitrate dynamics and downstream export.

Glacial and biogenic particles create similar fjord color
This research indicates that fjord waters shaped by glacial meltwater and coccolithophore blooms can look nearly the same in satellite reflectance, even though their particle types differ.

Marine biogeochemical cycles can shift into alternative regimes
This research indicates that marine biogeochemical cycles can shift into alternative dynamic regimes under extreme environmental perturbations and usually return to the original regime when the perturbation is removed.

Sulfuric and nitric acids drive iron dissolution differently by air layer
This research indicates that iron dissolution in a megacity changes by air layer and particle size, with sulfuric acid dominating in the upper mixing layer and submicron aerosols, while nitric acid is more important near the ground.

Polar ostracod mitochondrial genomes show shared organization
This research indicates that five deep-sea pelagic ostracod species from the Arctic and Antarctic have similar mitochondrial genome organization, with some species-specific variation.

Local human disturbances reduce coral reef climate refugia
This research indicates that local human disturbances such as pollution and land-use change can suppress potential coral reef climate refugia, especially on inshore turbid reefs.

Atlantic Ocean δ13CDIC reconstructed from sparse historical data
This research indicates that a probabilistic machine learning model can reconstruct Atlantic Ocean δ13C DIC, expand the usable data record, and produce a gridded 3D dataset.
