TL;DR: In this article, the authors present a compilation of trace element data from approximately sixty published works for NIST SRM 611 and NISTSRM 613 and provide useful new working values for these reference materials.

TL;DR: This article used a lake-sediment record from the montane Mediterranean zone of Morocco to address the question of whether these events were also felt in temperate continental regions, finding evidence of arid intervals of similar duration, periodicity and possibly timing to those in the tropics.

TL;DR: It is inferred that surface hydrology is an important factor in the development of cryoconite bacterial communities inCryoconite holes on three Arctic glaciers in Svalbard using terminal restriction fragment length polymorphism of the 16S rRNA locus.

TL;DR: The results unequivocally demonstrate that all the presently known Toba tephra occurrences in peninsular India belong to the 75,000 yr B.P. Toba eruption as discussed by the authors.

TL;DR: Composts are well suited for promoting the re-vegetation of contaminated sites; however, care must be taken to ensure that very short-term leaching pulses of heavy metals induced by compost amendment are not of sufficient magnitude to cause contamination of the wider environment.
