Benguela Upwelling Filaments Are a Significant Pathway of New Nutrients to the South Atlantic Subtropical Gyre

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract In the transition zones between eastern boundary upwelling regions and subtropical gyres, upwelling and offshore moving filaments generated by frontal instabilities play an important role in the gyre‐ward transport of new nutrients and phytoplankton biomass. However, quantification of such transport using field data remains sparse.

Why Are There Agulhas Rings? [PDF]

open access: yesJournal of Physical Oceanography, 1999
Abstract The recently proposed analytical theory of Nof and Pichevin describing the intimate relationship between retroflecting currents and the production of rings is examined numerically and applied to the Agulhas Current. Using a reduced-gravity 1½-layer primitive equation model of the Bleck and Boudra type the authors show that, as the theory ...

Preconditioning of Polynya Formation by Ocean Mixing at Maud Rise, Antarctica

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic open‐ocean polynyas trigger vigorous wintertime convection, influencing ocean circulation and atmospheric processes. In the Weddell Sea, interaction between the Weddell Gyre and the Maud Rise seamount generates a Taylor column that favors polynya formation.

Glacial‐Interglacial Shifts in Export Productivity and Iron Flux in the Indian Sector of the Southern Ocean

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract Greater ocean export productivity fueled by enhanced delivery of iron to the Sub‐Antarctic Zone (SAZ) of the Southern Ocean is hypothesized to play an important role in reducing atmospheric CO2 during Pleistocene glaciations. However, spatial variability in iron input and nutrient availability complicates quantifying the integrated impact of ...

Intensified Oxygen Minimum Zone in Response to Both Insolation Maxima and Carbon Dioxide‐Driven Warmth in the Tropical North Atlantic

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract Oxygen (O2) is essential for almost all life on Earth, but O2 concentrations are rapidly declining in the oceans under global warming, stressing marine ecosystems and biogeochemical cycles. Numerical model simulations suggest greatly expanded North Atlantic Oxygen Minimum Zones (OMZs) under warm Pliocene conditions, but sparse data limit ...

Advancing the pneumatic method to assess xylem vulnerability to embolism among distinct growth forms

open access: yesPlant Biology, Volume 28, Issue 5, Page 1385-1398, August 2026.
Our study shows that pneumatic vulnerability curves can be constructed across contrasting growth forms, with P50 showing the closest agreement across methods. Repeated relative water content measurements improved water potential estimation for graminoid culms. Abstract Drought‐driven plant mortality is closely linked to xylem embolism. Building useful,
