Feeding site selection by woodland caribou in north-central British Columbia

Rangifer, 2000
We examined the foraging habits of the northern woodland caribou ecotype {Rangifer tarandus caribou) at the scale of the individual feeding site. Field data were collected in north-central British Columbia over two winters (Dec 1996-Apr 1998). We trailed

Chicxulub central crater structure: Initial results from physical property measurements and combined velocity and gravity modeling

, 2004
The Chicxulub crater in Mexico is a nearly pristine example of a large impact crater. Its slow burial has left the central impact basin intact, within which there is an apparently uneroded topographic peak ring.

Sequence of infilling events in Gale crater, Mars: Results from morphology, stratigraphy, and mineralogy

, 2013
Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine their origin.

Three-dimensional joint inversion of traveltime and gravity data across the Chicxulub impact crater

, 2009
In 2005 an extensive new seismic refraction data set was acquired over the central part of the Chicxulub impact crater, allowing us to image its structure with much better resolution than before.
