Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Valanginian to Barremian Benthic Foraminifera from ODP Site 766 (Leg 123, Indian Ocean) [PDF]
A Valanginian to Barremian bathyal foraminiferal assemblage (118 taxa belonging to 51 genera) is documented from ODP Site 766, drilled near the foot of the Exmouth Plateau off northwest Australia.

The structurally controlled Otūwhero estuary on the SE boundary of Abel Tasman National Park is a small partially filled incised valley. The small size, limited number of fluvial inputs, accessibility and surrounding land use made it an ideal candidate on which to investigate potential climate‐induced estuarine behaviour. Surficial sediment samples and

Biostratigraphy of the Danian/Selandian transition: A case study from Kamestan anticline section, northwest of Izeh city in Khuzestan province, Southern Iran [PDF]
The planktonic foraminifera turnover across the Danian-Selandian boundary (early to late Paleocene, ~60 Ma) has been studied in the Kamestan anticline section. The studied interval span planktonic foraminifera zones P2-P3.

Representing Zooplankters: An Example from the Foraminifera
Because of their excellent preservation record, testate zooplankters provide valuable proxy ocean climate data through the Quaternary–Recent. Commonly, specimen abundances are sought, which are time-consuming to collect manually and require taxonomic ...

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

Holocene relative sea-level reconstruction for the central great barrier reef, Australia: a subtidal foraminiferal approach [PDF]
Contemporary subtidal foraminiferal samples and associated environmental Information were collected from two embayments along the central Great Barrier Reef coastline, Australia, to comprehend the relationship of benthic foraminiferal assemblages with ...

Abstract Limiting global warming to 1.5°C will require carbon dioxide removal, and Ocean Alkalinity Enhancement (OAE) is increasingly being explored as a marine carbon dioxide removal pathway. However, benthic biological responses remain much less constrained than water‐column processes and planktonic responses, even though calcareous benthic ...

Abstract The South Pacific Ocean (SPO) hosts diverse biogeographical environments including the productive Peru‐Chile upwelling region and ultra‐oligotrophic subtropical gyre; however, vast areas are understudied regarding the cycling of dissolved calcium (Ca) and strontium (Sr), and distribution of major biomineral‐forming pelagic marine organisms ...
