Active shoreline of Ontario Lacus, Titan: A morphological study of the lake and its surroundings
[1] Of more than 400 filled lakes now identified on Titan, the first and largest reported in the southern latitudes is Ontario Lacus, which is dark in both infrared and microwave. Here we describe recent observations including synthetic aperture radar (SAR) images by Cassini’s radar instrument (l = 2 cm) and show morphological evidence for active material transport and erosion. Ontario Lacus li...
متن کاملBathymetry and absorptivity of Titan’s Ontario Lacus
[1] Ontario Lacus is the largest and best characterized lake in Titan’s south polar region. In June and July 2009, the Cassini RADAR acquired its first Synthetic Aperture Radar (SAR) images of the area. Together with closest approach altimetry acquired in December 2008, these observations provide a unique opportunity to study the lake’s nearshore bathymetry and complex refractive properties. Av...
متن کاملHydrocarbon lakes on Titan
The Huygens Probe detected dendritic drainage-like features, methane clouds and a high surface relative humidity (∼50%) on Titan in the vicinity of its landing site [Tomasko, M.G., and 39 colleagues, 2005. Nature 438, 765–778; Niemann, H.B., and 17 colleagues, 2005. Nature 438, 779–784], suggesting sources of methane that replenish this gas against photoand charged-particle chemical loss on sho...
متن کاملShoreline Features of Titan’s Ontario Lacus from Cassini/VIMS Observations
We analyze observations of Titan’s south polar lake Ontario Lacus obtained by Cassini ’s Visual and Infrared Mapping Spectrometer during the 38th flyby of Titan (T38; 2007 December 5). The near-closest-approach observations have the highest signal-to-noise, the finest spatial resolution, and the least atmospheric influence of any near-infrared lake observation to date. We use the large, spatial...
متن کاملAnthropogenic influences on hydrocarbon contents of sediments deposited in eastern Lake Ontario
The amounts and types of extractable hydrocarbon components in sediment cores from the Rochester Basin of eastern Lake Ontario provide a record of environmental changes that have accompanied the settlement and population growth of the surrounding land areas. Sediments deposited prior to the mid-1800s contain low concentrations of hydrocarbons that are dominated by land-plant wax components. Con...
