Publicación DOI 10.1109/lagirs48042.2020.9165686From Space to Earth: physical and biological impacts of glacier dynamics in the marine system by means of Remote Sensing at Almirantazgo Bay, Antarctica2020-03-01; ; Brondi, F.To determine the biological and physical mechanisms between Lange glacier and its pro-glacier marine system located in Almirantazgo bay, King George Island, Antarctica, specific variables were determined through remote sensing approaches shown in this work. These preliminary results will allow relating the dynamics of both systems, the glacier, and the marine ecosystem. The information for the estimation of surface flux velocity of the glacier was derived through Radar satellite images (Sentinel-1) by means of offset tracking, the bathymetry was derived from a Multi-beam Echo Sounder, and the Digital Elevation Modell was obtained by means of a Remotely Piloted Aircraft; Finally, the biological parameters were derived from MODIS and OLCI images for the analysis of satellite data to have a first insight to the characteristics of the marine system. This information will help to build the first frame needed to study through remote sensing approaches, the mechanisms that govern the interface among 'Lang Glacier' and the 'Almirantazgo Bay' at King George Island, Antarctica. - Some of the metrics are blocked by yourconsent settings

Publicación DOI 10.1109/igarss.2019.8898008CALVING DYNAMICS OF TWO OUTLET GLACIERS OF THE SOUTH PATAGONIAN ICEFIELD DERIVED FROM TERRASAR-X AND TANDEM-X2019; Floricioiu, DanaWe estimate the calving flux of two major outlet glaciers belonging to the South Patagonian Icefield (SPI), Perito Moreno and Upsala Glaciers, between 2011 and 2015 comparing it to the correspondent total mass balance in a similar time period (2012-2016). Additionally, time series of calving rates are calculated back to 2008, allowing a detailed analysis of the frontal advance/retreat and velocity change of these glaciers. - Some of the metrics are blocked by yourconsent settings

Publicación DOI 10.1109/lagirs48042.2020.9165619Calving Dynamics Derived from Satellite Sar Data in Support of Mass Balance Estimations in Lange Glacier, Antarctica2020-3-1; ; Cassasa, GinoWe present calving flux, calving rate, frontal retreat and volume change rate results in Lange Glacier from 2015 to 2017, including also velocity calculations in 2015, 2017 and 2018. The peak velocities at glacier front were between 1.0 and 1.5 [md-1] near the center line with a maximum frontal retreat of 100 [m]. The glacier presents almost no volume change rate during the period analyzed and the average ice discharge is 0.026 [km3 yr-1].Scopus© Citations 1 3 - Some of the metrics are blocked by yourconsent settings
