TL;DR: A marine glacial record from the upper 600 m of the AND-1B sediment core recovered from beneath the northwest part of the Ross ice shelf is presented and well-dated, ∼40-kyr cyclic variations in ice-sheet extent linked to cycles in insolation influenced by changes in the Earth’s axial tilt (obliquity) during the Pliocene are demonstrated.

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 article, a 10m-thick lower-middle Miocene marine sedimentary sequence from southwestern Sardinia has been used to estimate the age of the Liguro-Provencal Basin.

TL;DR: In this paper, the magnetic properties of leaves from different tree species from the same location were compared, and it was observed that leaves of evergreen species, like Quercus ilex, present much higher magnetic intensities than those of deciduous species like Platanus sp., suggesting that leaves accumulate magnetic pollutants during their whole lifespan.

TL;DR: A database of magnetic susceptibility measurements on different non-ordinary chondrites (C, E, R, and ungrouped) populations is presented and compared to our previous similar work on ordinary chondites as discussed by the authors.
