Abstract Transformative lunar science will be driven by the accessibility, recovery, and return to Earth of geological specimens. Isolated boulders, rock exposures, rocky craters at south pole all provide opportunities for geologic characterization sampling crust. Here, we present results orbital mapping region surrounding using Lunar Reconnaissance Orbiter Narrow Angle Camera images (0.5–2 m p...

Our collection of meteorites recovered here on Earth contain over 200 samples believed to have originated Mars. It is commonly accepted that these rocks were launched as ejecta during the formation impact craters. The majority are young and basaltic representing only a small fraction martian surface. Previous studies examined impacts into basalt or other competent material, but material bias re...

Abstract Environmental factors shape the structure and functioning of benthic communities. In coastal zones southwestern Baltic Sea, boulder fields represent one most productive habitats, supporting diverse communities that provide many ecosystem services. this study, influence geological characteristics on biodiversity associated hard-bottom was investigated at two different spatial scales (fe...

Abstract Large, rarely mobile boulders are observed globally in mountainous bedrock channels. Recent studies suggest that high concentrations of could be associated with channel morphological adjustment. However, a process‐based understanding large boulder effects on morphology is limited, and data scarce ambiguous. Here, we develop theory steady‐state width slope as function concentration. Our...

The timing and magnitude of Holocene glacial oscillations in most currently ice-free areas Antarctica remain unknown. This work focuses on the recent deglaciation northern sector Fildes Peninsula, King George Island, Antarctic Peninsula. ice cap covering ca. 90% island has receded since Last Glacial Maximum exposed 29 km2 land. We reconstruct its history based a dataset 12 36Cl exposure ages ob...
