Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Metals Coprecipitation with Barite: Nano-XRF Observation of Enhanced Strontium Incorporation
Hazardous Waste, 2020 Coprecipitation can be an effective treatment method for the removal of environmentally relevant metals from industrial wastewaters such as produced waters from the oil and gas industry. The precipitation of barite, BaSO4, through the addition of sulfate

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

Barium and its Importance as an Indicator of (Paleo)Productivity
Anais da Academia Brasileira de CiênciasBarium (Ba) is a trace element which occurs predominantly as barite mineral (BaSO4) in the marine environment. Previous work suggests that barite concentrations are related to the organic carbon flux and marine biological debris in the water column ...

Phytoremediation of Wastewater From Oil Well Drilling: Potential of Different Plant Species
Water Environment Research, Volume 98, Issue 5, May 2026.Purple fountain grass (Cenchrus setaceus “Rubrum”) is a promising plant for using in constructed wetlands treating complex oil drilling effluents. ABSTRACT This study evaluated the removal of contaminants present in wastewater from oil well drilling in the presence of three plant species: water hyacinth (Eichhornia crassipes), cattail (Typha ...

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

The Variable Impact of Heinrich Events on the Benthic Environment of the Porcupine Abyssal Plain
Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.Abstract Heinrich events (HEs) are Pleistocene climate disturbances caused by massive freshwater discharges from the Laurentide Ice Sheet via the Hudson Strait. They appear in marine sediments as layers of ice‐rafted detritus (IRD) and significantly impact the benthic environment.
