An Ecological Perspective on Dolomite Formation in Great Salt Lake, Utah

Frontiers in Earth Science, 2020
Protodolomite was detected in sediments from Great Salt Lake (GSL), Utah, United States, that have no history of elevated temperature or pressure, conditions that are thought to promote dolomitization of sedimentary carbonates. Protodolomite was abundant

Scientific drilling of sediments at Darwin Crater, Tasmania [PDF]

Scientific Drilling, 2019
A 70 m long continental sediment record was recovered at Darwin Crater in western Tasmania, Australia. The sediment succession includes a pre-lake silty sand deposit overlain by lacustrine silts that have accumulated in the ∼816 ka ...

Perfluoroalkyl substances and extractable organic fluorine in surface sediments and cores from Lake Ontario

Environment International, 2013
Fourteen perfluoroalkyl substances (PFASs) including short-chain perfluorocarboxylates (PFCAs, C4–C6) and perfluoroalkane sulfonates (PFSAs, C4 and C6) were measured in surface sediment samples from 26 stations collected in 2008 and sediment core samples

Biostratigraphic and magnetostratigraphic synthesis of the Celebes and Sulu Seas, Leg 124 [PDF]

, 1991
During ODP Leg 124, late middle Eocene to Quaternary sediment sequences were recovered from 13 holes drilled at five sites in the Celebes and Sulu basins. Paleomagnetic measurements and biostratigraphic studies using calcareous nannofossils, planktonic

Holocene Carbon Burial in Lakes of the Uinta Mountains, Utah, USA

Quaternary, 2019
Recent research suggests that organic matter sequestered in lake sediment comprises a larger component of the global carbon cycle than once thought, yet little is known about carbon storage in mountain lakes.

Evidence for a mid-Pleistocene change of ice-drift pattern in the Nordic seas [PDF]

, 2003
Sediment proxy records from a continuous, 1.5 million year long deep-sea sediment core from a site in the western Norwegian Sea were used to obtain new insights into the nature of palaeoceanographic change in the northern North Atlantic (Nordic seas ...

Vertical Stratification of Sediment Microbial Communities Along Geochemical Gradients of a Subterranean Estuary Located at the Gloucester Beach of Virginia, United States

Frontiers in Microbiology, 2019
Subterranean estuaries (STEs) have been recognized as important ecosystems for the exchange of materials between the land and sea, but the microbial players of biogeochemical processes have not been well examined.
