Improving Lunar Exploration with Robotic Follow-up [PDF]

, 2011
We are investigating how augmenting human field work with subsequent robot activity can improve lunar exploration. Robotic "follow-up" might involve: completing geology observations; making tedious or long-duration measurements of a target site or ...

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Effect of a Surficial Porous Brittle Layer on the Dynamics and Equilibrium Thickness of Europa’s Ice Shell

The Planetary Science Journal
Tectonic and cryovolcanic features on Europa suggest a dynamically active ice shell with a highly deformable near-surface brittle layer. Shell thickness estimates based on geological interpretation and thermal modeling vary from 10 km to more than 30 km.

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]

, 2018
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

Archaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Comparison of Reference Heights of O/N2 and ∑O/N2 Based on GUVI Dayside Limb Measurement

Space Weather, 2020
We define a new thermospheric concept, the reference heights of O/N2, referring to a series of thermospheric heights corresponding to the fixed ratios of O to N2 number density. Here, based on Global Ultraviolet Imager (GUVI) limb measurement, we compare
