Campbell, Bruce A.; Campbell, Donald B. (2022)Over its 57 yr history, the Arecibo telescope was used to produce radar maps of Venus that pioneered our understanding of surface landforms and geologic processes. The best spatial resolution of 1–2 km achievable with the ...
-
Bell Regio, Venus: Integration of remote sensing data and terrestrial analogs for geologic analysis Campbell, Bruce A.; Rogers, Patricia G. (1994)The geology and surface morphology of Bell Regio (18'42"N, 32'58"E) are investigated using a combination of Magellan, Venera, and analogous terrestrial data. The properties of surface units are compared ...
-
Campbell, Bruce A.; Shepard, Michael K. (2003)We examine the relative importance of coherent and incoherent echo components in near-nadir radar scattering from self-affine surfaces. The coherent component, important only for observations at small incidence angles ...
-
Campbell, Bruce A. (2002)In a recent Icarus article, Shkuratov and Bondarenko (2001) propose a model for the depth of the lunar regolith based on 70-cm radar observations and near-infrared spectroscopy. This model treats the regolith as a single ...
-
Ghent, Rebecca R.; Hayne, Paul O.; Bandfield, Joshua L.; Campbell, Bruce A.; Allen, Carlton C.; Carter, Lynn M.; Paige, David A. (2014)We present a new empirical constraint on the rate of breakdown of large ejecta blocks on the Moon based on observations from the Lunar Reconnaissance Orbiter (LRO) Diviner thermal radiometer. We find that the rockiness of ...

Wells, K. S.; Campbell, Donald B.; Campbell, Bruce A.; Carter, Lynn M. (2010)

Carter, Lynn M.; Campbell, Bruce A.; Holt, John W.; Philips, Roger J.; Putzig, Nathaniel E.; Mattei, Stefania; Seu, Roberto; Okubo, Chris H.; Egan, Anthony F. (2009)The SHARAD instrument on the Mars Reconnaissance Orbiter detects subsurface interfaces beneath lava flow fields northwest of Ascraeus Mons. The interfaces occur in two locations; a northern flow that originates south of ...
-
Campbell, Bruce A.; Watters, Thomas R.; Morgan, Gareth A. (2021)The extensive Medusae Fossae Formation (MFF) along the dichotomy boundary on Mars has geologic features indicative of wind erosion of low-density material. There is evidence suggesting a water ice component, but with ...

Campbell, Bruce A.; Carter, Lynn M.; Campbell, Donald B.; Nolan, M.; Chandler, John F.; Ghent, R. R.; Hawke, B. R.; Anderson, Ross F.; Wells, K. (2010)
-
Ghent, Rebecca R.; Leverington, David W.; Campbell, Bruce A.; Hawke, B. Ray; Campbell, Donald B. (2005)Earth-based radar can be used in conjunction with other data sets collected remotely or in situ to characterize the physical and chemical properties of the lunar regolith. We use previously existing and newly acquired ...
-
Ghent, Rebecca R.; Campbell, Bruce A.; Hawke, B. Ray; Campbell, Donald B. (2008)We present new Earth-based radar observations of ejecta associated with the lunar Orientale impact basin. We can distinguish (1) a block-poor ejecta facies composing a concentric halo of mantling material 10 m or greater ...
-
Campbell, Bruce A.; Shepard, Michael K. (1997)Radar images from Magellan have provided tremendous opportunities to study the geology and bulk dielectric properties of Venus, but many questions can only be addressed through direct photography or imaging spectroscopy ...

Restano, Marco; Plaut, Jeffrey J.; Campbell, Bruce A.; Gim, Yonggyu; Nunes, Daniel; Bernardini, Fabrizio; Egan, Anthony F.; Seu, Roberto; Philips, Roger J. (2015)
-
Campbell, Bruce A.; Campbell, Donald B.; Morgan, Gareth A.; Carter, Lynn M.; Nolan, Michael C.; Chandler, John F. (2015)We combine Earth-based radar maps of Venus from the 1988 and 2012 inferior conjunctions, which had similar viewing geometries. Processing of both datasets with better image focusing and co-registration techniques, and ...

Nunes, Daniel Cahn; Smrekar, Suzanne E.; Safaeinili, Ali; Holt, John W.; Phillips, Roger J.; Seu, Roberto; Campbell, Bruce A. (2010)Martian gullies, found on steep slopes along broad mid-latitudinal bands, have morphologies resembling those of water-carved gullies on Earth and have been dated to <10 Ma. As such, one of the leading hypotheses, though ...
