Magnetic and petrologic characterization of synthetic Martian basalts and implications for the surface magnetization of Mars
(2009-01-01)
A suite of synthetic Martian basalts is generated with the objective of providing fundamental material properties data for use in modeling and interpretation of mission data. We systematically evaluate the effects of major ...
Paleointensity applications to timing and extent of eruptive activity, 9°–10°N East Pacific Rise
(2006-06-08)
Placing accurate age constraints on near-axis lava flows has become increasingly important given the structural and volcanic complexity of the neovolcanic zone at fast spreading ridges. Geomagnetic paleointensity of submarine ...
Source of tiny wiggles in Chron C5: A comparison of sedimentary relative intensity and marine magnetic anomalies
(2003-06-14)
In addition to the well-established pattern of polarity reversals, short-wavelength fluctuations are often present in both sea-surface data ("tiny wiggles") and near-bottom anomaly data. While a high degree of correlation ...
r-mode seen in inertial frame
(2005-01-01)
This animation by Chad Hanna shows an oscillating neutron star seen by an inertial observer. The red dots show the motion of a fluid element, dominated by the star's rotation. The black lines and dotes show the pattern of ...
r-mode seen in a frame rotating with the star
(2005-01-01)
The figure on the right shows the same oscillating star, now as seen by an observer rotating with the star. The red dots now do not rotate, and the the black lines show the pattern of the mode rotating backwards -- in a ...
Time-lapse photos showing paths of Jupiter and Saturn 2000-2001
(2001-01-01)
This photo animation of Jupiter (brighter) and Saturn shows them each moving from west to east then appearing to change direction at nearly the same time and move from east to west (retrograde). Finally, they change direction ...
On the duration of magnetochrons C24r and C25n and the timing of early Eocene global warming events: Implications from the Ocean Drilling Program Leg 208 Walvis Ridge depth transect
(2007-01-01)
Five sections drilled in multiple holes over a depth transect of more than 2200 m at the Walvis Ridge (SE Atlantic) during Ocean Drilling Program (ODP) Leg 208 resulted in the first complete early Paleogene deep-sea record. ...
Subbasin Characteristics and Hydrological Response to Anticipated Urbanisation
(2008-01-01)
This study investigated the relationship between the hydrological response of a river basin to anticipated urbanisation and its subbasin characteristics by applying a hydrological model (HSPF) with land use scenarios ...
