Retrieval of digital elevation models from Sentinel-1 radar data – open applications, techniques, and limitations
Open Geosciences - Tập 13 Số 1 - Trang 532-569 - 2021
AbstractWith the launch of Sentinel-1 in 2014, a new era of openly accessible
spaceborne radar imagery was begun, and its potential has been demonstrated
throughout all fields of applications. However, while interferometric approaches
to detect surface deformations are continuously being published, only a few
studies address the derivation of digital elevation models (DEMs) from
Sentinel-1 data. T...
Modern sands derived from the Vertiskos Unit of the Serbomacedonian Massif (N. Greece): a preliminary study on the weathering of the Unit
Open Geosciences - Tập 4 Số 3 - Trang 465-477 - 2012
Abstract Modern sand samples were collected from the Vertiskos Unit of the
Serbomacedonian Massif, northern Greece, and were examined for their texture and
mineralogical composition. They were collected from active channels and
torrents. The textural study demonstrated that these modern sands are moderately
to very-poorly sorted, often polymodal in grain size distribution, texturally
and mineralog...
Cretaceous sedimentary blanketing and tectonic rejuvenation in the Western Klamath moutains: Insights from thermochronology
Open Geosciences - Tập 2 Số 2 - Trang 138-151 - 2010
Abstract We present new thermochronometric analyses of 4 samples from the
Western Klamath mountains in California and Oregon, together with a
re-evaluation of available geological constraint from a thermo-tectonic
perspective. Early Cretaceous cooling of basement samples is seen to reflect
significant exhumation by normal faulting, linked to the Separation Episode
during which the Klamah region wa...
Pressure-temperature-fluid constraints for the Emmaville-Torrington emerald deposit, New South Wales, Australia: Fluid inclusion and stable isotope studies
Open Geosciences - Tập 4 Số 2 - Trang 287-299 - 2012
Abstract The Emmaville-Torrington emeralds were first discovered in 1890 in
quartz veins hosted within a Permian metasedimentary sequence, consisting of
meta-siltstones, slates and quartzites intruded by pegmatite and aplite veins
from the Moule Granite. The emerald deposit genesis is consistent with a typical
granite-related emerald vein system. Emeralds from these veins display colour
zonation a...
The relationship between intraseasonal tropical variability and ENSO and its modulation at seasonal to decadal timescales
Open Geosciences - - 2011
Abstract The intraseasonal tropical variability (ITV) patterns in the tropical
troposphere are documented using double space-time Fourier analysis. Madden and
Julian oscillations (MJO) as well as equatorial coupled waves (Kelvin and
Rossby) are investigated based on the NCEP/NCAR Reanalysis data for the
1977–2006 period and the outputs of an intermediate ocean-atmosphere coupled
model named LODCA-...
Continental and oceanic precipitation régime in Europe
Open Geosciences - - 2009
AbstractThis work considers continentality from the point of view of an annual
course of precipitation. It assesses continentality according to percentage of
precipitation in summer and winter half year, ratio of precipitation in summer
to winter half year and the period of half year precipitation in the area of WMO
Region VI (Europe). Region VI can be divided into five main regions according to
t...
Forward modelling of the Bureba escarpment (Rioja Trough, N-Spain)
Open Geosciences - - 2009
Abstract In this work I use the numerical model TAO to study the evolution of
the Bureba escarpment, sitting at the watershed between Duero and Ebro Basins
and draining into the Rioja Trough. Facies correlation across this area is
troublesome through lack of age-dates and therefore timing of tectonosedimentary
events is controversial. Numerical modelling should shed some light on the
evolution of ...

Trophic State Index derivation through the remote sensing of Case-2 water bodies in the Mediterranean region
Open Geosciences - - 2014
AbstractThe main goal of this study is the derivation of Carlson’s Trophic State
Index (TSI) through the remote sensing of four different Case-2 waters in the
Mediterranean region such as Cyprus and Greece. TSISD is derived through
extensive field ground campaign of Secchi Disk Depth measurements for the
Asprokremmos Dam, located in Paphos District in Cyprus; Alyki Salt Lake, located
in Larnaca Di...
