Tracing the Migration of Fronts in the Pacific Southern Ocean Across the Mid‐Pleistocene Transition

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Southern Ocean is a key driver of global climate variability, yet its dynamics during the Mid‐Pleistocene Transition (MPT; ∼1.25–0.7 Ma) remain poorly understood, especially in the South Pacific sector. The Polar Frontal Zone (PFZ) underwent significant latitudinal shifts during this critical period of climate reorganization.

Sea‐Level and Frontal Controls on Diatom Deposition During the Mid‐Pleistocene Transition, Southern Cape Basin

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Indian‐Atlantic Ocean Gateway modulates interocean exchange and influences large‐scale ocean circulation, including the Atlantic Meridional Overturning Circulation. Site U1479 (Cape Basin; IODP Expedition 361) lies at the Benguela‐Agulhas transition and records interactions among the Indian, Atlantic, and Southern Ocean basins during the ...

Chaetoceros gracilis AS A BIOINDICATOR OF SEDIMENT QUALITY

open access: yesJurnal Ilmu dan Teknologi Kelautan Tropis, 2014
Chronic sediment toxicity tests could be used to evaluate the effects of sediment on critical stages in the life of an organism like invertebrate larvae and microalgae. Microalgae play an important role in aquatic ecosystem due to their role as producer in food chain producing organic matter and oxygen through photosynthesis process.

Exploring Global Patterns of Trace Metal Limitation as a Regulator of the Distribution of Dominant Marine Phytoplankton Groups

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
By synthesizing decades of culture data with modern oceanographic datasets, we modelled trace metal limitation of phytoplankton. Our analysis reaffirms the critical role of iron but additionally highlights a significant, growing impact of zinc on the biological pump in future oceans.

Reversible Regime Change: Climate‐Driven Phytoplankton Community Shifts in the Cariaco Basin, Venezuela

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Phytoplankton communities are integral to oceanic biogeochemical cycles and are sensitive indicators of climate‐driven environmental variability. Long‐term time series capture this variability, allowing us to unravel the effects of environmental change on local communities.
