TL;DR: In this article, the authors present new data from Pliocene marine sediments recovered offshore of Adelie Land, East Antarctica, that reveal dynamic behaviour of the East Antarctic ice sheet in the vicinity of the low-lying Wilkes Subglacial Basin during times of past climatic warmth.

TL;DR: Microfossils enable reconstruction of the ecological history of the past 102–103 years or even more, and, in conjunction with statistical modeling approaches using independent proxy records of climate and human-induced environmental changes, future research will enable workers to better address Shifting Baseline Syndrome and separate anthropogenic impacts from background natural variability.

TL;DR: In this paper, the authors examined the fluvial to marine transition zone (FMTZ) of the Mekong River delta, along a total channel length of ~660 km.

TL;DR: In this paper, the authors investigated the drivers of Holocene sea surface temperature (SST) and sea ice extent in the North Pacific Ocean, and the Okhotsk and Bering Seas, as inferred from sediment core records, by using the alkenone unsaturation index as a biomarker of SST and abundances of sea ice-related diatoms (F. cylindrus and F. oceanica) to explore controlling mechanisms in the high-latitude Pacific.

TL;DR: In this article, a 58m-long sediment core was recovered in the southwestern part of the Okhotsk Sea for high resolution paleocenography, and an age model of the core was obtained by accelerator mass spectrometry (AMS) 14C dating of planktonic foraminifer shells, oxygen-isotope stratigraphy of benthic calcite, and tephrochronology, resulting in a core-bottom age of 115kyr.
