Improved Sea Surface Height from Satellite Altimetry in Coastal Zones: A Case Study in Southern Patagonia
(Institute of Electrical and Electronics Engineers, 2017-08)
High-resolution 20-Hz Jason-2 satellite altimetry data obtained from crossing tracks numbered 52 and 189 in San Matias Gulf, Argentina, are compared with a 22-month-long time series of sea level measured by a bottom pressure ...
Malvinas Current variability from Argo floats and satellite altimetry
(Blackwell Publishing Ltd, 2016-07)
The Malvinas Current (MC) is an offshoot of the Antarctic Circumpolar Current (ACC). Downstream of Drake Passage, the northern fronts of the ACC veer northward, cross over the North Scotia Ridge (NSR) and the Malvinas ...
Validation of satellite altimetry by kinematic GNSS in central East Antarctica
(Copernicus Group, 2017-05)
Ice-surface elevation profiles of more than 30 000 km in total length are derived from kinematic GNSS (GPS and the Russian GLONASS) observations on sledge convoy vehicles along traverses between Vostok Station and the East ...
Coastal applications from nadir altimetry: Example of the X-TRACK regional products
In the coastal ocean zones, satellite altimetry data processing and interpretation poses specific difficulties, due to the interaction of the radar signal with land topography, inaccuracies in some of the geophysical ...
A comparison of the annual cycle of sea level in coastal areas from gridded satellite altimetry and tide gauges
In this work we compare the annual component of sea level variations derived from 478 worldwide- distributed tide gauges with the annual component computed from a weekly gridded multi-mission altimeter product. Gridded ...
Airborne laser altimetry survey of Glaciar Tyndall, Patagonia
(ELSEVIER SCIENCE BV, 2007-10)
The first airborne laser altimetry measurements of a glacier in South America are presented. Data were collected in November of 2001 over Glaciar Tyndall, Torres del Paine National Park, Chilean Patagonia, onboard a Twin ...
Satellite Altimetry and Current-Meter Velocities in the Malvinas Current at 41°S: Comparisons and Modes of Variations
(American Geophysical Union, 2017-12)
Three year long current-meter arrays were deployed in the Malvinas Current at 418S below a satellite altimeter track at about 10 years intervals. Surface geostrophic velocities (SGV) derived from satel- lite altimetric ...
An investigation of ensemble-based assimilation of satellite altimetry and tide gauge data in storm surge prediction
Cyclogenesis and long-fetched winds along the southeastern coast of South America may lead to floods in populated areas, as the Buenos Aires Province, with important economic and social impacts. A numerical model (SMARA) ...
VARIABILITY OF SUBPOLAR NORTH ATLANTIC CIRCULATION FROM ALTIMETRY
(Universidad de Concepción.Facultad de Ciencias Naturales y Oceanográficas., 2004)
