Killer asteroids : feasibility of using the IRTF to track near-earth objects
(Massachusetts Institute of Technology, 2006)The possibility of an asteroid or comet impact necessitates the tracking and cataloging of all such objects which could potentially impact Earth. Currently, no comprehensive catalog of Near Earth Objects (NEOs) exists which ... -
Lability of dissolved organic carbon in Arctic rivers on the North Slope of Alaska
(Massachusetts Institute of Technology, 2007)Rivers are an important pathway of organic carbon-mobilization in the arctic, and their influence is projected to grow as precipitation and soil temperatures increase in response to highlatitude warming. This study addresses ... -
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 ... -
Low rare earth element concentration impact glass from the K/T Boundary at Beloc
(Massachusetts Institute of Technology, 2011)This paper seeks to describe an impact glass from the K/T boundary layer at Beloc that is depleted in rare earth elements (REE) relative to continental crust. It is widely agreed that a large bolide struck the Yucatan ... -
Lower Charles River bathymetry : 108 years of fresh water
(Massachusetts Institute of Technology, 2017)The Lower Charles River has been a heavily utilized urban river that runs between Cambridge and Boston in Massachusetts. The recreational usage of the river is dependent on adequate water depths and there have been no ... -
Lunar farside cratering,
(Massachusetts Institute of Technology, 1970) -
A machine learning model of Manhattan air pollution at high spatial resolution
(Massachusetts Institute of Technology, 2014)A machine-learning model was created to predict air pollution at high spatial resolution in Manhattan, New York using taxi trip data. Urban air pollution increases morbidity and mortality through respiratory and cardiovascular ... -
A machine-learning approach to aerosol classification for single-particle mass spectrometry
(Massachusetts Institute of Technology, 2017)Compositional analysis of atmospheric and laboratory aerosols is often conducted via single-particle mass spectrometry (SPMS), an in situ and real-time analytical technique that produces mass spectra on a single particle ... -
Magmatic processes that generated the rim andesites of Medicine Lake Volcano, N. California
(Massachusetts Institute of Technology, 2012)This paper characterizes the compositionally distinctive high-Na andesite lavas at Medicine Lake Volcano that erupted at ~100 ka and that built most of Medicine Lake's caldera. These high-Na lavas define a compositional ... -
Mantle thermal evolution of tidally-locked super-earths
(Massachusetts Institute of Technology, 2009)Most super-Earth (mass < 10M[mathematical symbol]) detection techniques are biased towards massive planets with close-in orbits. A planet's orbital decay timescale decreases with a lower semi-major axis, thereby providing ... -
Measuring channel mobility through the analysis of area-based change in analog experiments, with insights into alluvial environments
(Massachusetts Institute of Technology, 2008)We quantify the mobility of alluvial river channels in order to better understand the relationship between channel mobility and fluvial environment. We analyze five analog experiments, performed between 2002 and 2007 at ... -
Measuring transit timing variations of exoplanets using small telescopes
(Massachusetts Institute of Technology, 2010)Transits of exoplanets were observed from June 2009 through January 2010. Six transit light curves are presented in this paper for three planets: WASP-10b, WASP- 11/HAT-P-10b, and TrES-3. Measurements of the planetary ... -
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 ... -
The Mercurian magma ocean, first crust, and implications for planetary formation mechanisms
(Massachusetts Institute of Technology, 2010)The size of the Mercurian core and the low ferrous iron bearing silicate content of its crust offer constraints on formation models for the planet. Here we consider a bulk composition that allows endogenous formation of ... -
Mercury emissions inventories in the Lake Superior states
(Massachusetts Institute of Technology, 2016)Mercury pollution can cause harmful impacts on human health and the environment, a concern that is magnified in marine environments like the Great Lakes. While there are many local, national, and global efforts to track ... -
Methane and carbon dioxide cycling in soils of the Harvard Forest
(Massachusetts Institute of Technology, 2018)Soil is Earth's largest terrestrial carbon pool (Oertel et al., 2016) and can act as a net source of greenhouse gases (GHG). However, if organic material accumulates in soils faster than it is converted to CO2 by cellular ... -
A method for atmospheric hydrocarbon determination.
(Massachusetts Institute of Technology, 1966) -
A method for synthesizing sedimentary structures generated by migrating bedforms
(Massachusetts Institute of Technology, 1978) -
Methods for the study of virus adsorption to metal oxide in order to improve ceramic water filters
(Massachusetts Institute of Technology, 2006)As of 2002, 1.1 billion people lacked access to clean water, causing several million deahts each year from highly-infectious enteric diseases. It has been recognized that an appropriate way of addressing this problem may ... -
Microstructural study of two-phase marbles in simple shear
(Massachusetts Institute of Technology, 2009)Microstructural and textural observations have been conducted on synthetic calcite with 20 wt% quartz deformed in simple shear using transmission electron microscopy and selected-area diffraction. The marbles were deformed ...
