Photometric and spectral analysis of the distribution of crystalline and amorphous ices on Enceladus as seen by Cassini
(Massachusetts Institute of Technology, 2006)
Photometric and Spectral analysis of data from the Cassini Visual and Infrared Mapping Spectrometer (VIMS) has yielded intriguing findings regarding the properties and composition of the surface of Saturn's satellite ...
Local and expert knowledge in experienced mining communities : the case of a proposed uranium mine in Crownpoint
(Massachusetts Institute of Technology, 2007)
Public access to science is an essential environmental justice component of any mining development. Both limited public access to professional scientific knowledge and little acknowledgment by professionals of the contributions ...
Mechanisms governing avulsions in transient landscapes : analysis of the May 2006 Suncook River avulsion in Epsom, New Hampshire
(Massachusetts Institute of Technology, 2007)
Avulsions, or rapid changes in the location of a river, usually occur in environments such as deltas, floodplains, and alluvial fans where net-deposition can raise the bed of the river above its floodplain. Avulsions are ...
A coupled atmosphere-ocean model of thermohaline circulation, including wind-driven gyre circulation with an analytical solution
(Massachusetts Institute of Technology, 2006)
A parameter representing circulation due to wind forcing is added to the thermohaline circulation model of Marotzke (1996). The model consists of four boxes and is governed by a system of two differential equations governing ...
Sizing the X-ray spectral resolution limits of the REgolith X-ray Imaging Spectrometer (REXIS) instrument at Asteroid 1999RQ36
(Massachusetts Institute of Technology, 2013)
The REgolith X-ray Imaging Spectrometer (REXIS), a Charge-Coupled Device (CCD)-based coded aperture soft X-ray (0.3-7.5 keV) telescope for remote geochemical X-ray Fluorescence (XRF) spectrometry, will be flying on board ...
Complex lipids in microbial mats and stromatolites of Hamelin Pool, Shark Bay, Australia
(Massachusetts Institute of Technology, 2014)
Stromatolites, columnar rock-like structures, are potentially some of the oldest, microbially mediated fossils visible in the rock record; if biogenesis is able to be confirmed for these ancient stromatolites, some being ...
Characterizing fault structure and general morphology of the Tensleep Sandstone of Teapot Dome, Wyoming as it relates to industrial carbon sequestration
(Massachusetts Institute of Technology, 2006)
Consistent data demonstrates a rise in global atmospheric concentrations of carbon, in the form of carbon dioxide. A large portion of the current atmospheric concentration is due to emissions from the burning of fossil ...
Rotationally resolved visible spectroscopy of the Asteroid 1 Ceres
(Massachusetts Institute of Technology, 2013)
This thesis was designed to make spectroscopic measurements of Ceres within the visible spectrum, specifically within the wavelength range of 6000 and 7000 Angstroms. The asteroid was observed for 6 nights, for lengths of ...
Comparison of PSF fitting methods for determining centroids of stars
(Massachusetts Institute of Technology, 2013)
This paper shows a comparison of four fitting models used in order to calculate the centroids for twelve stars. The offsets for each coordinate are calculated with respect to the mean of the coordinates for varying aperture ...
Using thermochronology to constrain exhumation in the Swiss-Italian Alps
(Massachusetts Institute of Technology, 2008)
Twelve bedrock samples were collected from Ticino, Switzerland and Northern Italy for thermochronological studies using the (U-Th)/He technique on zircon and apatite and fission track on subset of zircons. Nine samples ...
