The PanCam instrument for the ExoMars rover
(2017-07-01) - Journal article
The scientific objectives of the ExoMars rover are designed to answer several key questions in the search for life on Mars. In particular, the unique subsurface drill will address some of these, such as the possible existence ...
Changes in Timor Strait hydrology and thermocline structure during the past 130 ka
(2016-11-15) - Journal article
Paleostudies of the Indonesian Throughflow (ITF) are largely based on temperature and salinity reconstructions of its near surface component, whereas the variability of its lower thermocline flow has rarely been investigated. ...
Sedimentary DNA from a submerged site reveals wheat in the British Isles 8000 years ago
(2015-02-27) - Journal article
The Mesolithic-to-Neolithic transition marked the time when a hunter-gatherer economy gave way to agriculture, coinciding with rising sea levels. Bouldnor Cliff, is a submarine archaeological site off the Isle of Wight in ...
From convergent plate margin to arc-continent collision : formation of the Kenting Mélange, southern Taiwan
(2016-10) - Journal article
The Kenting Mélange on the Hengchun Peninsula, Taiwan, formed through tectonic shearing of subduction complex lithologies, probably within the plate boundary subduction channel between the Eurasian and Philippine Sea plates, ...
Factors controlling the thermoluminescence spectra of rare earth doped calcium fluoride
(2017-04) - Journal article
Thermoluminescence spectra of rare earth doped calcium fluoride samples, both powder and single crystal, were recorded over the temperature range from 25 K to 673 K. Although some broad band features exist, the spectra are ...
From subduction to collision in the northern Tibetan plateau : evidence from the early Silurian clastic rocks, northwestern China
(2012-01) - Journal article
The Qilian Orogen records early Paleozoic collisional suturing of the Qaidam Block and the Central Qilian Block to the North China Craton. The composition and U-Pb age of detrital zircons and the composition of Cr-spinels ...
Plausible microbial metabolisms on Mars
(2013) - Journal article
Sophie L Nixon, Claire R Cousins and Charles S Cockell explore the possible ways in which any Martian life could get energy.
Emerging biogeochemical views of Earth's ancient microbial worlds
(2015-12-01) - Journal article
Microbial processes dominate geochemical cycles at and near the Earth’s surface today. Their role was even greater in the past, with microbes being the dominant life form for the first 90% of Earth’s history. Most of their ...
Planetary science and exploration in the deep subsurface : results from the MINAR Program, Boulby Mine, UK
(2017-04) - Journal article
The subsurface exploration of other planetary bodies can be used to unravel their geological history and assess their habitability. On Mars in particular, present-day habitable conditions may be restricted to the subsurface. ...
An ESA roadmap for geobiology in space exploration
(2016-01) - Journal article
Geobiology, and in particular mineral-microbe interactions, has a significant role to play in current and future space exploration. This includes the search for biosignatures in extraterrestrial environments, and the human ...
