Comparing the Weathering Environment of Permian and Modern Antarctic Proglacial Lake Sediments: Mineralogical and Geochemical Study [PDF]
, 2017 The Antarctic continent has been in a polar to subpolar position since the Permian period. Although it has experienced milder climates over this time period as evidenced by corals in the fossil record, Antarctica did undergo extensive glaciation during ...

Radiocarbon reservoir ages from freshwater lakes, south Georgia, sub-Antarctic: Modern analogues from particulate organic matter and surface sediments [PDF]
, 2004 Lake sediments have the potential to preserve proxy records of past climate change. Organic material suitable for radiocarbon dating often provides age control of such proxy records.

The surface features and soil pattern of the Hamilton basin [PDF]
, 1967 The Holocene history of the Hamilton basin and development of the soil pattern are closely related. The basin was partly filled by the large alluvial fan of the Waikato River which partly buried a hilly, ash-covered landscape.

Draft genomes of two strains of flavobacterium isolated from lake washington sediment. [PDF]
, 2015 We report sequencing the genomes of two new Flavobacterium strains isolated from Lake Washington sediment. From genomic contents, versatile lifestyles were predicted but not bona fide methylotrophy.

Paleolakes and life on early Mars [PDF]
Two distinct directions have begun to elucidate key parameters in the search for extinct life on Mars. Carbonate sediments, deposited about 10,000 years ago in association with biological activity, have been sampled from the paleolake beds of Lake Vanda ...

Controls on Cyclic Formation of Quaternary Early Diagenetic Dolomite [PDF]
, 2018 The origin of sedimentary dolomite and the factors that control its formation within the geological record remain speculative. In most models, dolomite formation is linked to evaporative conditions, high water temperature, increasing Mg/Ca ratio ...
