Bathymetry 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 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 کاملActive 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 Volume Estimation of Reservoirs using OLI Imagary
Nowadays using field depth measurement to estimate capacity of water reservoirs is a costly and time consuming method. In this regard, different multiple techniques of remote sensing method has been adopted. In this study, a radiation and reflection based model was introduced to estimating the bathymetry and water capacity of reservoir by images of OLI sensor. For this, at May 17, 2015 water de...
متن کاملDetermination of the molar absorptivity of NADH.
The molar absorptivity of NADH at 340 nm has been determined by an indirect procedure in which high-purity glucose is phosphorylated by ATP in the presence of hexokinase, coupled to oxidation of the glucose-6-phosphate by NAD+ in the presence of glucose-6-phosphate dehydrogenase. The average value from 85 independent determinations is 6317 liter mol-1 cm-1 at 25 degrees C and pH 7.8. The overal...
