TL;DR: This is the first set of consistently dated marine sediment cores enabling paleoclimate scientists to evaluate leads/lags between circulation and climate changes over vast regions of the Atlantic Ocean.
Journal ArticleDOI
Definition of new trace-metal proxies for the controls on organic matter enrichment in marine sediments based on Mn, Co, Mo and Cd concentrations
TL;DR: In this paper, the authors present a comprehensive database of published trace metal concentration data in modern organic-rich deposits from a variety of marine settings, showing that high Cd/Mo values are typical for sediments from continental margin upwelling settings whereas Co and Mn concentrations (expressed as Co∗Mn values) are high in samples from hydrographically restricted marine basins.
Journal ArticleDOI
Osmium isotope evidence for two pulses of increased continental weathering linked to Early Jurassic volcanism and climate change

TL;DR: In this paper, the sedimentary records of two such episodes of environmental change, the Toarcian oceanic anoxic event (T-OAE) and preceding Pliensbachian-Toarcian (Pl-To) event (both possibly linked to the Karoo-Ferrar LIP), are investigated using a new suite of geochemical proxies that have not been previously compared.
Journal ArticleDOI
Basalt‐seawater interaction, the Plenus Cold Event, enhanced weathering and geochemical change: deconstructing Oceanic Anoxic Event 2 (Cenomanian–Turonian, Late Cretaceous)
TL;DR: In this paper, three sections (Eastbourne, Sussex, UK; Raia del Pedale, Campania, Italy; and Tarfaya, Morocco) recording this event illustrate the influence on marine geochemistry of mafic volcanic rock-seawater interaction, anoxia to euxinia, and re-oxygenation and cooling during the so-called Plenus Cold Event.
Journal ArticleDOI
Hydrological and associated biogeochemical consequences of rapid global warming during the Paleocene-Eocene Thermal Maximum

TL;DR: The Paleocene-Eocene Thermal Maximum (PETM) hyperthermal, ~56 million years ago (Ma), is the most dramatic example of abrupt Cenozoic global warming as mentioned in this paper.
