Ocean acidification is one of the main stressors affecting marine ecosystems. Rare CO2 vents offer a unique opportunity to investigate the response of benthic ecosystems to acidification. However, the benthic habitats that have been investigated so far are mainly very shallow water (≤5 m depth) and, therefore, to habitats that are poorly representative of the broad range of habitats that occur on the continental shelf. Here, we show that a decrease from pH 8.1 to...

Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report the first high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a ≥10-fold increase in dust deposition during glacials and a ≤5-fold...

The composition of the lower oceanic crust in the Wadi Khafifah section of the southern Samail (Oman) ophiolite

Jill VanTongeren, Peter Kelemen, Carlos Garrido, Marguerite Godard, Karen Hanghoj, Michael Braun & Julian Pearce
The composition of the intrusive gabbroic lower oceanic crust remains poorly characterized in comparison to the extrusive portion of the oceanic crust, especially for intermediate-fast spreading mid-ocean ridges. This is a consequence of limited exposures of extant lower oceanic crust and of ophiolites similar to mid-ocean ridge crust. One of the best analogues for mid-ocean ridge crust is the southern Samail ophiolite that formed during a period of rapid seafloor spreading above a nascent subduction...
