The martian Residual South Polar Cap (RSPC) is a 1–10 m thick deposit of permanent CO 2 ice perched on the much larger H 2 O ice cap. The CO 2 ice is dissected into mesas by erosional landforms that can be broadly classified as (i) quasi-circular pits, (ii) heart-shaped pits, (iii) linear troughs, and (iv) moats. We use HiRISE (25–50 cm/px) images taken at a cadence of days to months to track m...

Offshore wind farms have developed rapidly in Jiangsu Province, China, over the last decade. The existence of offshore turbines will inevitably impact hydrological and sedimentary environments. In this paper, a digital elevation model (DEM) intertidal sandbank southern Province from 2018 to 2020 was constructed based on improved remote sensing waterline method. On basis, stability analysed, com...

coastal zone of sri lanka is a key to sustainable development of the country. the erosion of country’s coastal zone has been identified as a long standing problem. therefore, coastal sediment dynamics around the country has to be identified to develop an appropriate coastal zone management plan. remote sensing and gis techniques can be used for quantitative and qualitative analyses of coastal p...

The extent of the burnt zone has been established by drilling. The thickest section, about 75 metres deep, underlies the Dry Lake gulch near the base of the coal measures. Other profiles of the bllrnt zone give an average thickness of about 25 metres, although thinning and some discontinuity is appartlnt. The present area of the burnt zone amounting to about 3.5 square kilometres is evidently o...
