TL;DR: Sediment data from shallow marine cores in the western Ross Sea are presented that exhibit well dated cyclic variations, and which link the extent of the East Antarctic ice sheet directly to orbital cycles during the Oligocene/Miocene transition, suggesting that orbital influences at the frequencies of obliquity and eccentricity controlled the oscillations of the ice margin at that time.

TL;DR: In this paper, the Cenomanian-Turonian Boundary Event (CTBE) is reflected by one of the most extreme carbon cycle perturbations in Earth's history and is characterized by widespread occurrence of sediments indicating oxygen deficiency in oceanic waters (Oceanic Anoxic Event 2 = OAE 2).

TL;DR: In this paper, the authors show that, over the past 1.36 million years, wet winters in the northcentral Mediterranean tend to occur with high contrasts in local, seasonal insolation and a vigorous African summer monsoon.

TL;DR: In this article, the authors presented the upper 247.8 m composite depth of the overall 569 m long DEEP site sediment succession from the central part of Lake Ohrid (Macedonia, Albania).

TL;DR: The Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) project is an international research initiative to study the influence of major geological and environmental events on the biological evolution of lake taxa.
