A geological carbon cycle sink hosted by ocean crust talus breccias

Rosalind M. Coggon, Elliot J. Carter, L.J.C. Grant, A. Evans et autres

Abstract Calcium carbonate precipitation in ageing ocean crust sequesters carbon dioxide dissolved in seawater through seafloor weathering reactions, influencing atmospheric CO 2 concentrations on million-year timescales. However, this crustal carbon sink, and the extent it balances CO 2 degassing during crustal formation …

Unveiling factors affecting the magnetic signature of MORBs and their long-term variation

Claudio Robustelli Test, Chiara Amadori, Michelle Harris, Thomas M. Belgrano et autres

Marine magnetic anomalies provide fundamental information on plate tectonics, seafloor spreading, and geomagnetic field variations over time. It has long been debated whether the long-term variations of the marine magnetic anomalies are related to records of paleointensity variations or the progressive off-axis …

Carbon-Uptake in Upper Oceanic Crust via Ridge Flank Hydrothermal Exchange: Insights from the South Atlantic Transect - IODP Expeditions 390/393

Jennifer Lington, Rosalind M. Coggon, A. Evans, L.J.C. Grant et autres

The formation, alteration and eventual recycling of crust formed at mid-ocean ridges (MORs) constitutes a significant component of the long-term global carbon cycle. The hydrothermal circulation of seawater-derived fluids through the oceanic crust results in the chemical alteration of not only the …

Petrography and geochemistry of a calcite- and zeolite-cemented basalt-clast talus breccia from Site U1557, South Atlantic Transect, IODP Expeditions 390/393

Sulfur cycling in the gabbroic section of the Oman ophiolite

Ana Patrícia Jesus, Harald Strauß, Mário A. Gonçalves, Michelle Harris et autres

We present sulfur mineralogy and isotope geochemistry from the gabbro transect of the Oman Drilling Project to unravel the sulfur cycle during hydrothermal alteration of the plutonic oceanic crust. The sheeted dike–gabbro transition (Hole GT3A) shows low sulfide‑sulfur concentrations (GT3A median = …

Unlocking success: community engagement for enhanced HIV care outcomes

Sarah E. Wiehe, Tammie L. Nelson, Bridget Hawryluk, Unai Miguel Andres et autres

Though social determinants are the primary drivers of health, few studies of people living with HIV focus on non-clinical correlates of insecure and/or fragmented connections with the care system. Our team uses linked clinical and multisector non‐clinical data to study how residential …

Ocean crustal veins record dynamic interplay between plate-cooling-induced cracking and ocean chemistry

A. Evans, Rosalind M. Coggon, Michelle Harris, Elliot J. Carter et autres

• Ocean crustal veins reflect dynamic evolution in ocean chemistry and plate cooling. • Veins widths and strain increase with crustal age, while vein densities remain constant. • Elemental mapping reveals multiple precipitation and fracturing episodes. • Ocean plate cooling drives vein …

Time scales and mechanisms of uranium uptake in altered ocean crust; observations from the ∼15 million year-old site 1256 in the eastern equatorial Pacific

Morten B. Andersen, Joel Rodney, Heye Freymuth, Flurin Vils et autres

The alteration of ocean crust through hydrothermal seawater circulation facilitates chemical exchange between Earth’s surface and interior. Hydrothermal alteration leads to uranium (U) removal from seawater and net U uptake by the ocean crust, particularly during low temperature alteration that occurs on …

497 Fast-Tracking Varicose Vein Treatment: A Post COVID Pathway for Effective Care

Nelson Lee, S Tsirigotis, Michelle Harris, Pranav Somaiya

Abstract Aim Standard treatment pathways for varicose veins (VV) consist of a referral, first clinic appointment, vascular ultrasound (VUS) and a follow-up appointment to determine eligibility for intervention. Multiple appointments cause delays in treatment. Publication of the ‘NHS 10-year long-term plan’ and …
