Orbital and In Situ Observation of Transverse Aeolian Ridges at Zhurong Landing Site

Journal of Geophysical Research E: Planets, 2023
Abstract A large amount of transverse aeolian ridges (TARs) bedforms exist in the Zhurong rover landing region. The acquisition of high‐resolution data from the orbiter and the rover from Tianwen‐1 mission provides an excellent opportunity to study the geological characteristics of TARs.

Mega-ripples in Iran: A new analog for transverse aeolian ridges on Mars

Icarus, 2016
Abstract A new terrestrial analog site for transverse aeolian ridges (TARs) is described in this study. The Lut desert of Iran hosts large ripple-like aeolian bedforms, with the same horizontal length scales and patterns of TARs on Mars. Different classes of TARs and different types of other aeolian features such as sand dunes, zibars, dust devil ...

Ripples, Transverse Aeolian Ridges, and Dark-Toned Sand Dunes on Mars: A Case Study in Terra Sabaea

Journal of Geophysical Research E: Planets, 2021
AbstractRipples, transverse aeolian ridges (TARs), and dark‐toned sand sheets and dunes are common aeolian bedforms on the Martian surface. They are important for understanding the nature of present‐day Martian sediments and regional aeolian processes. Here we present a case study investigation of ripples, TARs, a dark‐toned sand sheet, and dunes in an

Morphology of transverse aeolian ridges (TARs) on Mars from a large sample: Further evidence of a megaripple origin?

Icarus, 2017
Abstract Using HiRISE digital terrain models (DTMs), we developed a large morphological dataset to examine the three-dimensional shape, size, and scaling of Martian transverse aeolian ridges (TARs). Considerable debate exists on the characteristic morphology of TARs and the origins of these enigmatic bedforms.

Transverse Aeolian Ridges on Mars: First results from HiRISE images

Geomorphology, 2010
Abstract Three images obtained by the High Resolution Imaging Science Experiment (HiRISE) were analyzed for the information they could provide regarding Transverse Aeolian Ridges (TARs) on Mars. TARs from five locations in a HiRISE image of the floor of Ius Chasma show remarkably symmetric (cross-sectional) profiles, with average slopes for the ...

Transverse Aeolian Ridges (TARs) on Mars II: Distributions, orientations, and ages

Icarus, 2011
Transverse Aeolian Ridges (TARs), 10 m scale, ripple-like aeolian bedforms with simple morphology, are widespread on Mars but it is unknown what role they play in Mars’ wider sediment cycle. We present the results of a survey of all Mars Global Surveyor Narrow angle images in a pole-to-pole study area, 45° longitude wide.
