Abstract Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15N tracer incubations and a δ18O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer Cosmonaut Sea.

Tectonics on Early Earth Driven by Earth's Changing Shape During Tidal Recession of the Moon
Abstract Few fragments of Earth's earliest crust have survived, and so this formative period of our planet's history is shrouded in mystery. To leverage the limited data available, it is important to understand all the processes that could have shaped our young planet.

Evolution of Air‐Sea Fluxes in Modeled Long‐Lived Mesoscale Eddies in the South Atlantic Ocean
Abstract Mesoscale eddies modify physical and biogeochemical properties, facilitating the exchange of heat and CO2 between the surface, mixed‐layer and ocean interior. Most state‐of‐the‐art Earth System Models fail to resolve mesoscale processes O $O$(10–100 km) due to computational constraints, thus contributing to uncertainties in current and future ...

Abstract We report results from a meridional transect performed along 150°W, 30°S to 60°S in the Southern Ocean (SO). This study aimed to document the rates of conditioning of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW), which are formed during deep mixing events in the austral winter.

Synoptic Pathways of Mid‐Depth Salinity Maximum Intrusions in the South Brazil Bight
Abstract Cross‐shelf exchanges play a crucial role in distributing heat, salt, and biogeochemical properties between the continental shelf and the open ocean. Among the processes shaping these exchanges, the intrusion of warm and salty waters (mid‐depth Salinity Maximum, Smax ${S}_{\max }$) remains poorly understood in the South Brazil Bight (SBB).

Redistribution of Light Absorption by Chlorophyll Decline Delays Warming by Up to a Decade
Abstract Chlorophyll regulates solar radiation absorption in the upper ocean, influencing the ocean's mean state and climate. However, its response to climate change in Earth System Models (ESMs) remains unclear. Here, we show that in addition to well‐known effects on the carbon cycle, projected chlorophyll decline reduces the absorption of solar ...

Preferential Orientations of Subjovian Patera and Northern Hemisphere Mountain Populations on Io
Abstract Io's surface hosts numerous mountains and volcanic paterae generated by processes that occur at depth, including tidal heating and the resultant crustal recycling and subsidence stresses. Global trends in the shape and orientation of surface features could provide insight into these subsurface processes.

Abstract Headwater streams play a critical role in the physical, chemical, and biological functions of downstream waters. However, predicting their specific impact on a landscape scale remains a grand challenge, prompting the development of the river corridor framework to integrate the study of stream channels and hyporheic zones with that of adjacent ...
