TL;DR: Palaeogene sediments obtained during the Arctic Coring Expedition are analysed, showing that large quantities of the free-floating fern Azolla grew and reproduced in the Arctic Ocean by the onset of the middle Eocene epoch and that onset and termination of the Azolla phase depended on the degree of oceanic exchange between Arctic Ocean and adjacent seas.

TL;DR: This paper reported stratigraphically extensive ice-rafted debris, including macroscopic dropstones, in late Eocene to early Oligocene sediments from the Norwegian-Greenland Sea that were deposited between about 38 and 30 million years ago.

TL;DR: Northern high-latitude terrestrial climate estimates for the Eocene to Oligocene interval, based on bioclimatic analysis of terrestrially derived spore and pollen assemblages preserved in marine sediments from the Norwegian–Greenland Sea indicate a cooling of ∼5 °C in cold-month (winter) mean temperatures to 0–2‬C, and a concomitant increased seasonality before the Oi-1 glaciation event.

TL;DR: In this article, integrated, astronomically tuned age models for a relatively expanded section of the Eagle Ford Group (Texas, USA) from the Shell Iona-1 research core, which encompass >8 myr ranging from the earliest Cenomanian to the earliest Coniacian, were described.

TL;DR: In this paper, the authors developed a magnetic reversal stratigraphy for the Eocene-Oligocene interval in the Norwegian-Greenland Sea, which is the best-preserved record of the Oligocene and Eocene in the Northern Hemisphere high latitudes.
