Observations from working with a simple mathematical model of light absorption by small particles in the ocean
(Massachusetts Institute of Technology, 2008)
In order to investigate the possibility of using oceanic visual spectrum data (i.e., ocean color) to differentiate between phytoplankton cell types, a simple mathematical model of light absorption was constructed in MATLAB, ...
Pluto's atmosphere from the May 22, 2011 stellar occultation
(Massachusetts Institute of Technology, 2012)
This paper reports the observations and atmospheric fitting results from the May 22, 2011 stellar occultation by Pluto. Of the nine sites across the United States that attempted to observe the event, three obtained light ...
Paleomagnetism of Lonar impact glass
(Massachusetts Institute of Technology, 2008)
Several dozen impact glasses from Lonar Crater, in Maharashtra, India, were analyzed for evidence of impact-generated paleofields, and possible motional remanent magnetization. Lonar Crater formed when a meteorite impacted ...
Modeling sea surface height in the Gulf of Mexico
(Massachusetts Institute of Technology, 2008)
A model was created to form synthetic plots of sea surface height (SSH) from monthly SSH statistics in the Gulf of Mexico generated from satellite laser altimetry data. SSH is a signal of the upper ocean mixed layer heat ...
An overview of the volcano-tectonic hazards of Portland, Oregon, and an assessment of emergency preparedness
(Massachusetts Institute of Technology, 2011)
Portland, Oregon, lies within an active tectonic margin, which puts the city at risk to hazards from earthquakes and volcanic eruptions. The young Juan de Fuca microplate is subducting under North America, introducing not ...
Elemental and reactive gaseous mercury deposition and diurnal cycles over terrestrial environments
(Massachusetts Institute of Technology, 2011)
The atmospheric component of the global biogeochemical mercury cycle was studied to determine the mechanisms behind diurnal trends and amplitudes in elemental and reactive gaseous mercury concentrations over terrestrial ...
Transit timing variations of the exoplanet K2-25b
(Massachusetts Institute of Technology, 2017)
Transit light curves of the exoplanet K2-25b were studied to examine the possibility of transit timing variations (TTVs) in the system, which could imply the presence of a perturbing planet. Observations of K2-25b transits ...
Determining the effects of ocean perturbations on marine phytoplankton assemblages
(Massachusetts Institute of Technology, 2009)
The ocean provides a dynamic, constantly changing environment for marine phytoplankton. Understanding the effects of these changes on phytoplankton assemblages is fundamental when trying to anticipate future responses of ...
A paleomagnetic study of the angrite Sahara 99555
(Massachusetts Institute of Technology, 2009)
Sahara 99555 (SAH 99555) is the oldest dated angrite sample, a rare type of meteorite, and is only ~2 Myr younger than the age of the solar system (1, 2). SAH 99555 shows no post-cooling brecciation or weathering from the ...
Developing proxy radar data with the aid of cloud-to-ground lightning for a nowcasting system
(Massachusetts Institute of Technology, 2009)
Air traffic managers need up to date nowcast information over the entire CONUS for efficient operations in the National Airspace System. In areas of degraded or no radar coverage, cloud-to-ground lightning (provided by the ...
