Warm Middle Miocene Indian Ocean Bottom Water Temperatures: Comparison of Clumped Isotope and Mg/Ca‐Based Estimates
(Journal article; Peer reviewed, 2020)The middle Miocene is an important analogue for potential future warm climates. However, few independent deep ocean temperature records exist, though these are important for climate model validation and estimates of changes ... -
Was common Era glacier expansion in the Arctic Atlantic region triggered by unforced atmospheric cooling?
(Peer reviewed; Journal article, 2019-08-05)The timing and causes of Common Era (CE) glacier growth in the Arctic Atlantic region remain elusive. There is mounting evidence of advances that predate the Little Ice Age (1250–1850 CE); this challenges the view that ... -
Water Migration in the Subduction Mantle Wedge: A Two-Phase Flow Approach
(Journal article; Peer reviewed, 2019)Subduction zones are the main entry points of water into Earth's mantle and play an important role in the global water cycle. The progressive release of water by metamorphic dehydration induces important physical‐chemical ... -
Weathering of deep-sea hydrothermal sulfide deposits. Stability of heavy metals and implications for future mining activities
(Master thesis, 2016-12-20)During future mining operations on seafloor massive sulfide deposits, sulfidic material will be reworked and relocated at the seafloor, exposing the material to oxic conditions. In an oxic environment sulfidic material ... -
Winter Arctic Amplification at the synoptic timescale, 1979–2018, its regional variation and response to tropical and extratropical variability
(Journal article; Peer reviewed, 2021)We investigate winter Arctic Amplification (AA) on synoptic timescales and at regional scales using a daily version of the Arctic Amplification Index (AAI) and examine causes on a synoptic scale. The persistence, frequency ... -
Zippered Shear Zone Model for Interacting Shear Zones in the Borborema Province, Brazil, as Constrained by U-Pb Dating
(Peer reviewed; Journal article, 2019)Shear zones typically interact to form connected systems or networks to accommodate crustal deformation, but our knowledge of how this happens is fragmentary. Understanding branching and interacting shear zones requires ...
