Surface albedo and spectral variability of Ceres
(The Astrophysical Journal Letters, 2016-01-29)
Previous observations suggested that Ceres has active, but possibly sporadic, water outgassing as well as possibly varying spectral characteristics over a timescale of months. We used all available data of Ceres collected ...
Small-scale methane dispersion modelling for possible plume sources on the surface of Mars
(Geophysical Research Letters, 2012-10-11)
Intense interest in the characteristics of a methane source on Mars has been spurred by recent observations of a plume structure. The current NASA Mars Science Laboratory and future landers and orbiters will be tasked with ...
A chrono-geographic look at Mesolithic burials: an initial study
(Landesamt für Denkmalpflege und Archäologie Sachsen-Anhalt, 2016)
Over the past decade we have focused on two interrelated topics within Mesolithic burial studies, the relationship between burial number and burial date, and the chronology of Mesolithic sites with burials. Related to this ...
Calibrations of phase abundance, composition, and particle size distribution for olivine-orthopyroxene mixtures from reflectance spectra
(American Geophysical Union, 1986-10-10)
Spectral reflectance measurements of characterized (phase abundance, particle size) mixtures of olivine and orthopyroxene were utilized to define the correlations between spectral and albedo parameters of such assemblages ...
The role of wetland coverage within the near-stream zone in predicting of seasonal stream export chemistry from forested headwater catchments
(John Wiley & Sons Ltd., 2019-02-19)
Stream chemistry is often used to infer catchment‐scale biogeochemical processes. However, biogeochemical cycling in the near‐stream zone or hydrologically‐connected areas may exert a stronger influence on stream chemistry ...
Distribution of hydrated minerals in the north polar region of Mars
(Journal of Geophysical Research, 2009-01-28)
The previous discovery of extensive deposits of hydrated minerals in Olympia Planum in the north polar region of Mars by the Mars Express OMEGA instrument raises important questions about the origin and subsequent ...
Composition of Jupiter irregular satellites sheds light on their origin
(EDP Sciences, 2017)
Context. Irregular satellites of Jupiter with their highly eccentric, inclined and distant orbits suggest that their capture took place after the giant planet migration.
Aims. We aim to improve our understanding of the ...
Mineralogic constraints on sulfur-rich soils from Pancam spectra at Gusev crater, Mars
(Geophysical Research Letters, 2007-07-06)
The Mars Exploration Rover (MER) Spirit excavated sulfur-rich soils exhibiting high albedo and relatively white to yellow colors at three main locations on and south of Husband Hill in Gusev crater, Mars. The multispectral ...
Linking dominant rainfall-runoff event hydrologic response dynamics with nitrate and chloride load estimates of three boreal Shield catchments
(American Geophysical Union, 2021-08-21)
Understanding hydrological dynamics in boreal Shield catchments is critical for projecting changes in stream runoff and chemistry in a region that is sensitive to climate change. Previous work has mostly focused on a limited ...
Statement on Spectroscopic Imaging in Art Conservation: A New Tool for Materials Investigations
(Leonardo Electronic Archive, 2002-09)
