Short summary
We present a dataset of 23032 fossil occurrences of marine organisms from the Late Miocene to the Early Pliocene (~11 to 3.6 million years ago) from the Mediterranean Sea. This dataset will allow us, for the first time, to quantify the biodiversity impact of the Messinian salinity crisis, a major geological event that possibly changed global and regional climate and biota.

We explore new methods for ice-rafted debris detection in marine sediment cores to detect past climate changes and ice sheet dynamics. Traditional IRD detection methods are destructive and time-consuming. To alleviate this problem, we utilize non-destructive imaging techniques core material from the Indian Ocean. While promising, we found contamination to be an issue. Machine learning identifies density and chemical differences, but rigorous testing is needed to avoid false positives.

Short summary
Middle–Late Devonian sedimentary rocks are often punctuated by anoxic black shales. Due to their semi-regular nature, anoxic events may be linked to periodic changes in the Earth’s climate caused by astronomical forcing. We use portable X-ray fluorescence elemental records, measured on marine sediments from Germany, to construct an astrochronological framework for the Kellwasser ocean anoxic Crisis. Results suggest that the Upper Kellwasser event was preceded by a specific orbital configuration.

Differences exist in International Ocean Discovery Program (IODP) sediment lithification depending on the coring tool used. Advanced piston corers (APCs) display less pronounced lithification compared to extended core barrels (XCBs) of the same formation. The difference stems from the destruction of early cements between sediment grains and an
acoustic compactioncaused by the piston-core pressure wave. XCB cores provide a more accurate picture of the lithification of the original formation.

The Leeuwin Current transports warm water along the western coast of Australia: from the tropics to the Southern Hemisphere midlatitudes. Therewith, the current influences climate in two ways: first, as a moisture source for precipitation in southwestern Australia; second, as a vehicle for Equator-to-pole heat transport. In this study, we study sediment cores along the Leeuwin Current pathway to understand its ocean–climate interactions between 4 and 2 Ma.

Short summary
Age–depth models assign ages to sampling locations (e.g., in drill cores), making them crucial to the determined timing and pace of past changes. We present two methods to estimate age–depth models from sedimentological and stratigraphic information, resulting in richer and more empirically realistic age–depth models. As a use case, we (1) determine the timing of the Frasnian–Famennian extinction and (2) examine the duration of the Paleocene–Eocene Thermal Maximum (PETM), a potential deep-time analog for anthropogenic climate change.
