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. ...
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 ...
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 ...
Provenance of exhalites associated with the Lemarchant volcanogenic massive sulphide (VMS) deposit, central Newfoundland, Canada : insights from Nd isotopes and lithogeochemistry
(2017-11) - Journal article
Neodymium isotope data on exhalites and tuffs from the Cambrian Lemarchant volcanogenic massive sulphide (VMS) deposit provide insights into the tectonic environment of the Tally Pond group, Canada. New data from exhalites ...
Water-planets in the habitable zone: atmospheric chemistry, observable features, and the case of kepler-62e and -62f
(2013-10-01) - Journal article
Planets composed of large quantities of water that reside in the habitable zone are expected to have distinct geophysics and geochemistry of their surfaces and atmospheres. We explore these properties motivated by two key ...
Constraining ecosystem processes from tower fluxes and atmospheric profiles
(2011-07) - Journal article
The planetary boundary layer (PBL) provides an important link between the scales and processes resolved by global atmospheric sampling/modeling and site-based flux measurements. The PBL is in direct contact with the land ...
