[1] We produced a geologic/geomorphologic map of the Chaac-Camaxtli region of Io's leading anti-Jovian hemisphere using regional resolution (186 m/pixel) Galileo imaging data collected during orbit I27 (February 2000) integrated with lower resolution (1.4 km/pixel) color data, along with other Galileo imaging and spectral data. This is the first regional map of Io made from Galileo data. Nine color and geomorphologic units have been mapped, and the close proximity of dark and various colored… Expand

Mapping of the Culann–Tohil region of Io from Galileo imaging data
Abstract We have used Galileo spacecraft data to produce a geomorphologic map of the Culann–Tohil region of Io's antijovian hemisphere. This region includes a newly discovered shield volcano, TsũiExpand
Geologic mapping of the Zal region of Io
Abstract We produced a regional geologic map of the Zal region of Io's antijovian hemisphere using Galileo mission data. We discuss the geologic features, summarize the map units and structures thatExpand
Geology and activity around volcanoes on Io from the analysis of NIMS spectral images
Abstract The last two successful flybys of Io by Galileo in 2001 (orbits I31, I32) allowed the Near Infrared Mapping Spectrometer to enrich its collection of IR spectral image cubes of the satellite.Expand
Geologic mapping of the Hi’iaka and Shamshu regions of Io
Abstract We produced regional geologic maps of the Hi’iaka and Shamshu regions of Io’s antijovian hemisphere using Galileo mission data to assess the geologic processes that are involved in theExpand
Geologic mapping of the Amirani-Gish Bar region of Io: Implications for the global geologic mapping of Io
Abstract We produced the first geologic map of the Amirani–Gish Bar region of Io, the last of four regional maps generated from Galileo mission data. The Amirani–Gish Bar region has five primaryExpand
Volcanism on Io: New insights from global geologic mapping
Abstract We produced the first complete, 1:15 M-scale global geologic map of Jupiter’s moon Io, based on a set of monochrome and color Galileo–Voyager image mosaics produced at a spatial resolutionExpand
The Zamama Thor region of Io: Insights from a synthesis of mapping, topography, and Galileo spacecraft data

Volcanic history, geologic analysis and map of the Prometheus Patera region on Io
Data from Jupiter's moon Io returned by the Galileo spacecraft have been used to create a geologic map of Prometheus Patera, its associated flow field, and nearby features. We have identified theExpand
Volcanism on Io: Insights from Global Geologic Mapping
We are preparing a new global geo-logic map of Jupiter s volcanic moon, Io. Here we report the type of data that are now available from our global mapping efforts, and how these data can be used toExpand


Voyager and Galileo SSI views of volcanic resurfacing on Io and the search for geologic activity on Europa
Observational evidence and theoretical arguments suggest that Jupiter's satellite Europa could be geologically active and possess an "ocean" of liquid water beneath its surface at the present time.Expand
Mountains and Calderas on Io: Possible Implications for Lithosphere Structure and Magma Generation
Abstract The combination of Voyager images and newly acquired Galileo images with low illumination and resolutions ranging from 2 to 6 km/pixel now allows determination of the global distribution ofExpand
The mountains of Io: Global and geological perspectives from Voyager and Galileo
To search for local and global scale geologic associations that may be related to the internal dynamics of lo, we have completed a global catalog of all mountains and volcanic centers. We haveExpand
Active Volcanism on Io: Global Distribution and Variations in Activity
Abstract Io's volcanic activity has been monitored by instruments aboard the Galileo spacecraft since June 28, 1996. We present results from observations by the near-infrared mapping spectrometerExpand
Active Volcanism on Io as Seen by Galileo SSI
Abstract Active volcanism on Io has been monitored during the nominal Galileo satellite tour from mid 1996 through late 1997. The Solid State Imaging (SSI) experiment was able to observe manyExpand

Orogenic tectonism on Io
[1] We catalog 143 Ionian mountains (montes) and mountain-like features (mensae, tholi, plana, and small peaks) in order to investigate orogenic tectonism on Io. From this comprehensive list, weExpand
Landform Degradation and Slope Processes on Io: The Galileo View

Paterae, defined by the International Astronomical Union as “irregular crater[s], or complex one[s] with scalloped edges,” are some of the most prominent topographic features on Io. Paterae on Io areExpand
Galileo at Io: results from high-resolution imaging.
During late 1999/early 2000, the solid state imaging experiment on the Galileo spacecraft returned more than 100 high-resolution images of volcanically active Io, observing an active lava lake, an active curtain of lava, active lava flows, calderas, mountains, plateaus, and plains. Expand
