Journal ArticleDOI
Microbial Surface Colonization and Biofilm Development in Marine Environments
Hongyue Dang,Charles R. Lovell +1 more
TL;DR: Recent progress in the study of marine microbial surface colonization and biofilm development is synthesized and discussed and questions are posed for targeted investigation of surface-specific community-level microbial features to advance understanding ofsurface-associated microbial community ecology and the biogeochemical functions of these communities.
Journal ArticleDOI
Occurrence and abundance of 6-methyl branched glycerol dialkyl glycerol tetraethers in soils : Implications for palaeoclimate reconstruction
Cindy De Jonge,Ellen C. Hopmans,Claudia Zell,Jung-Hyun Kim,Stefan Schouten,Jaap S. Sinninghe Damsté +5 more
TL;DR: In this article, the authors quantified the fractional abundance of 6-methyl brGDGTs in globally distributed soils and showed that they are abundant components, comprising on average 24% of the total amount of brDGTs.
Journal ArticleDOI
The effect of improved chromatography on GDGT-based palaeoproxies
TL;DR: In this article, the authors presented a method based on two ultra-high performance liquid chromatography silica columns capable of separating a wide range of GDGTs with good resolution and which compares favorably with previously published methods.

Journal ArticleDOI
Southern ocean warming, sea level and hydrological change during the Paleocene-Eocene thermal maximum
TL;DR: In this paper, the authors identify the so-called "Paleocene-Eocene thermal maximum" (PETM) in a marine sedimentary sequence deposited on the East Tasman Plateau at Ocean Drilling Program (ODP) Site 1172 and show, based on the organic paleothermometer TEX86, that southwest Pacific sea surface temperatures increased from ~26 °C to ~33°C during the PETM.

Extended megadroughts in the southwestern United States during Pleistocene interglacials
Peter J. Fawcett,Josef P. Werne,Josef P. Werne,Josef P. Werne,R. Scott Anderson,Jeffrey M. Heikoop,Erik T. Brown,Melissa A. Berke,Susan J. Smith,Fraser Goff,Linda Donohoo-Hurley,Luz M. Cisneros-Dozal,Stefan Schouten,Jaap S. Sinninghe Damsté,Yongsong Huang,Jaime L. Toney,Julianna Fessenden,Giday WoldeGabriel,Viorel Atudorei,John W. Geissman,Craig D. Allen +20 more
TL;DR: Using molecular palaeotemperature proxies to reconstruct the mean annual temperature in mid-Pleistocene lacustrine sediment from the Valles Caldera, New Mexico, it is found that the driest conditions occurred during the warmest phases of interglacials, when the MAT was comparable to or higher than the modern MAT.
Journal ArticleDOI
Assessing biomarker syngeneity using branched alkanes with quaternary carbon (BAQCs) and other plastic contaminants
TL;DR: In this article, the authors studied the distribution of hydrocarbons in 26 rocks from different locations in the world, including three examples from the Paleoproterozoic Tawallah and McArthur Groups in northern Australia.
Journal ArticleDOI
Absence of seasonal patterns in MBT-CBT indices in mid-latitude soils
Johan W.H. Weijers,Beth Bernhardt,Francien Peterse,Josef P. Werne,Josef P. Werne,Jennifer A.J. Dungait,Stefan Schouten,Jaap S. Sinninghe Damsté +7 more
TL;DR: The degree of methylation and cyclization of bacteria-derived branched glycerol dialkyl glyceroline tetraether (GDGT) membrane lipids in soils depends on temperature and soil pH as discussed by the authors.
Journal ArticleDOI
Reconstruction of sea surface temperature variations in the Arabian Sea over the last 23 kyr using organic proxies (TEX86 and U37K
TL;DR: In this article, a comparison of NIOP905 and 74KL core top data with present-day SST (0-10 m) values indicates that both proxies yield temperatures similar to local annual mean SSTs.
