Kat published new paper in Geosciences. The project uses high resolution topography data to interpret two distinct forms of coastal dunes observed across The Bahamas. Signatures of beach-attached coastal foredunes provide a lateral indication of the maximum sea level transgression during past interglacial phases. You can access it here.

In October, Manica attended the Future Earth Research School on Sea Level Rise and Adaptation hosted by CMCC Foundation - Centro Euro Mediterraneo sui Cambiamenti Climatici. Over two weeks, the students learned about the causes and impacts of sea level rise, while learning from global experts on adaptation strategies.

Kat co-authored a manuscript in Nature. Using publicly available geochemical data from the Bakken shale, we identified basin-wide trends in redox sensitive elements (e.g., Mo and V), revealing expanding anoxic conditions through the Devonian-Carboniferous transition. Stepwise flooding in shallow interior basins, like the Williston, & onset of euxinia was widespread in this time, leading to large scale deposition of black shales and hydrocarbon reserves. In this work, we suggest that euxinic expansion in the shallow habitable zone of the oceans also contributed to the pattern and severity of Late Devonian mass extinction, and that hydrogen sulfide toxicity played a key role in shifting Phanerozoic biodiversity.
