“…Hence, Zipf et al . () explored the suitability of a drilling by‐product, that is drilling chips, for 10 Be determination in alpine and shallow polar ice cores. The promising comparison between 10 Be in the drilling chips with corresponding ice core samples from a cold Alpine glacier showed agreement within 2‐ s uncertainty for four of five sample combinations.…”

“…Ice cores offer unique multiproxy palaeoclimate records, but sample material is usually very limited and, thus, has to be carefully distributed for various proxy analyses. Hence, Zipf et al (2016) explored the suitability of a drilling byproduct, that is drilling chips, for 10 Be determination in alpine and shallow polar ice cores. The promising comparison between 10 Be in the drilling chips with corresponding ice core samples from a cold Alpine glacier showed agreement within 2-s uncertainty for four of five sample combinations.…”

This GGR biennial critical review covers developments and innovations in key analytical methods published since January 2014, relevant to the chemical, isotopic and crystallographic characterisation of geological and environmental materials. In nine selected analytical fields, publications considered to be of wide significance are summarised, background information is provided and their importance evaluated. In addition to instrumental technologies, this review also presents a summary of new developments in the preparation and characterisation of rock, microanalytical and isotopic reference materials, including a précis of recent changes and revisions to ISO guidelines for reference material characterisation and reporting. Selected reports are provided of isotope ratio analyses by both solution-nebulisation MC-ICP-MS and laser ablation-ICP-MS, as well as of radioactive isotope geochronology by LA-ICP-MS. Most of the analytical techniques elaborated continue to provide new applications for geochemical analysis, however it is noted that instrumental neutron activation analysis has become less popular in recent years, mostly due to the reduced availability of nuclear reactors to act as a neutron source. Many of the newer applications reported here provide analysis at increasingly finer resolution. Examples include atom probe tomography, a very sensitive method providing atomic scale information, nanoscale SIMS, for isotopic imaging of geological and biological samples, and micro-XRF, which has a spatial resolution many orders of magnitude smaller than conventional XRF

“…Considering previous work focusing on the age of alpine glaciers (see e.g. Jenk and others, 2009; Gabrielli and others, 2016; Uglietti and others, 2016; Zipf and others, 2016; Feng and others, 2019; Preunkert and others, 2019 a , 2019 b ; Bohleber and others, 2020), Guillet and others (2021) expected the age of near-bedrock ice in IAs to be ranging between several hundred and several thousand years. A dating method specific to ice containing no vegetal leftover and suitable for potential ice ages older than a few hundred years was therefore considered.…”

Ice aprons on steep high-alpine slopes: insights from the Mont-Blanc massif, Western Alps

et al. 2023

Ice aprons are defined as very small ice bodies covering steep rock slopes. They have only been the subject of increased scientific interest for a few years, despite the fact that they are a condition for mountaineering and obvious elements in the high-alpine landscapes. However, very little is known about their distribution, evolution and physical characteristics. In this paper, we review the existing knowledge on ice aprons, which have almost exclusively been investigated in the Mont-Blanc massif, Western Alps. We supplement this review with novel results from recent surveys of ice aprons. We used a wide array of methodologies, from remote sensing (multi-source imagery) to in situ (stakes and thermal monitoring) and laboratory (radiocarbon dating and texture analysis) glaciological investigations. In the Mont-Blanc massif, ice aprons occupy 4.2 km2 within the alpine permafrost zone. Temperature measured at the ice–rock interface is indeed largely negative. Thinness of ice aprons coupled with the cold context implies a quasi-stationary shear regime without basal Sliding. Only ice at the surface can possibly melt in warm periods. After a shrinking period from the end of the Little Ice Age to the mid-to-late-1960s, ice aprons experienced a short period of expansion, followed by an accelerated shrinkage since the beginning of the 21st century. This shrinkage now favours rockfall triggering and poses a serious threat to a glaciological heritage since ice aprons host several-thousand-year-old ice. Finally, we synthesize this information to assess the existing definition of ice aprons, and propose some future research directions.

“…Actinides various under development AMS is of utmost importance for dating samples on geological time scales. The spectrum of samples ranges from ice cores (Zipf et al, 2016), meteorites (Ott et al, 2014), deep sea manganese nodules and sediments, boulders from rock falls, landslides (Schwanghart et al, 2016) and glacier moraines (Landgraf et al, 2016) to lava samples from volcanic eruptions. DREAMS is also essential to research elds like astrophysics, climate, cosmo-chemistry or hydrogeology (Müller et al, 2016).…”

In the Ion Beam Center (IBC), various set-ups -electrostatic accelerators, ion implanters, plasma-based ion implantation equipment, low-energy ion tools, an ion microscope etc. -are combined into a unique facility for research and applications using ion beams. Almost all ions from stable chemical nuclides are available in the ion energy range from 10 eV to about 60 MeV. In addition to broad beams, also focused (down to 1 nm) and highly-charged (charge state up to 45 + ) ion beams, or ions extracted from a plasma can be provided. In total, the IBC operates more than 30 dedicated tools or beamline end-stations. The speci c expertise of IBC is the modi cation and analysis of solids by energetic ions aimed to develop novel materials for information technology, electronics or energy systems. In addition, ion beam analysis techniques became of increasing importance for interdisciplinary elds like geochemistry, climate or environmental research and resources technology. Special add-on services o ered ensure a successful realization of user experiments. Based on a long-term expertise, speci c equipment and common commercial procedures, the IBC is strongly active in the use of ion beam techniques for industrial applications aimed to initiate valuable product innovation.
