Spatio-temporal constraints on thrusting across fold-and-thrust belts worldwide [PDF]
Scientific ReportsFold-and-thrust belts (FTBs) are fundamental geological structures whose spatio-temporal evolution can be reconstructed using s–t graphs that integrate thrust positions and timing to trace sequences of activation and reactivation.

81Kr dating of 1 kg Antarctic ice [PDF]
Nature CommunicationsRecovering earth’s climate history from ice cores requires reliable dating of the ice. 81Kr is ideal for radiometric dating up to more than one million years, but the isotope is so rare that it has long been a challenge to apply 81Kr dating on ice cores ...

Ultra-slow aging dynamics of glass and its application to geological dating [PDF]
Nature CommunicationsThe ultra-slow relaxation dynamics of glasses at ambient temperature provide a promising alternative for dating glasses with extremely low isotopic content that cannot be dated using traditional radiometric methods.

An internally consistent dataset of δ13C-DIC in the North Atlantic Ocean – NAC13v1 [PDF]
Earth System Science Data, 2016 The stable carbon isotope composition of dissolved inorganic carbon (δ13C-DIC) can be used to quantify fluxes within the carbon system. For example, knowing the δ13C signature of the inorganic carbon pool can help in describing the amount of ...

Multi-decadal atmospheric and marine climate variability in southern Iberia during the mid- to late-Holocene [PDF]
Climate of the Past, 2019 To assess the regional multi-decadal to multi-centennial climate variability along the southern Iberian Peninsula during the mid- to late-Holocene record of paleo-environmental indicators from marine sediments were established for two sites in the ...

Symbiotic essential amino acids provisioning in the American cockroach, Periplaneta americana (Linnaeus) under various dietary conditions [PDF]
PeerJ, 2016 Insect gut microbes have been shown to provide nutrients such as essential amino acids (EAAs) to their hosts. How this symbiotic nutrient provisioning tracks with the host’s demand is not well understood.

Assessing the potential of amino acid 13C patterns as a carbon source tracer in marine sediments: effects of algal growth conditions and sedimentary diagenesis [PDF]
Biogeosciences, 2015 Burial of organic carbon in marine sediments has a profound influence in marine biogeochemical cycles and provides a sink for greenhouse gases such as CO2 and CH4.

Human Exploitation of Aquatic Landscapes. Editorial
Internet Archaeology, 2014 Aquatic landscapes such as rivers, lakes, and seas played an important role in past human behaviour, affecting modes of subsistence, patterns of mobility, access to material resources, and technological choices and their developments.

Towards a radiocarbon chronology of the Late-Glacial: Sample selection strategies [PDF]
, 2001 This paper outlines a dating program designed to test the reproducibility of radiocarbon dates on different materials of Late-Glacial age (plant macrofossils, fossil beetle remains, and the "humic" and "humin" chemical fractions of limnic sediments ...
