Early Jurassic–Early Cretaceous Calcareous Nannofossil Biostratigraphy and Geochemistry, Northeastern Iraqi Kurdistan: Implications for Paleoclimate and Paleoecological Conditions
Geosciences (Switzerland) - Tập 12 Số 2 - Trang 94
Early Jurassic- to Early Cretaceous-age calcareous nannofossils from the Sarki,
Sehkanyian, Sargelu, Naokelekan, Barsarin and Chia Gara formations are
investigated for the first time from the Warte area, northeastern Iraqi
Kurdistan. A range of isotopic and inorganic geochemical analyses are carried
out in order to reconstruct the paleoecological and paleoclimatic conditions
during which the Sarki...
Morphodynamic Trends of the Ribb River, Ethiopia, Prior to Dam Construction
Geosciences (Switzerland) - Tập 8 Số 7 - Trang 255
The meandering Ribb River flows in northwest Ethiopia to Lake Tana, the source
of the Blue Nile River. The river has already undergone changes due to several
human interventions, such as embanking, sand mining, water extraction and lake
level regulation for hydropower. At present, a dam and a weir are under
construction to store and divert water for irrigation. This will strongly alter
both water ...
A Validation of ERA5 Reanalysis Data in the Southern Antarctic Peninsula—Ellsworth Land Region, and Its Implications for Ice Core Studies
Geosciences (Switzerland) - Tập 9 Số 7 - Trang 289
Climate reanalyses provide key information to calibrate proxy records in regions
with scarce direct observations. The climate reanalysis used to perform a proxy
calibration should accurately reproduce the local climate variability. Here we
present a regional scale evaluation of meteorological parameters using
ERA-Interim and ERA5 reanalyses compared to in-situ observations from 13
automatic weathe...
Landfill Impacts on the Environment—Review
Geosciences (Switzerland) - Tập 9 Số 10 - Trang 431
Waste management (WM) is a demanding undertaking in all countries, with
important implications for human health, environmental preservation,
sustainability and circular economy. The method of sanitary landfilling for
final disposal of waste remains a generally accepted and used method but the
available scientific evidence on the waste-related environmental and health
effects is not conclusive. Com...
Geotechnical Properties of Two Pyroclastic Deposits Involved in Catastrophic Flowslides for Implementation in Early Warning Systems
Geosciences (Switzerland) - Tập 9 Số 1 - Trang 24
Air-fall pyroclastic deposits on steep slopes in Campania (Southern Italy) are
periodically subjected to rainfall-induced landslides that may evolve into
catastrophic flowslides. To protect built-up areas, early warning systems (EWSs)
have been implemented which are essentially based on pluviometric thresholds or
models unable to accurately monitor the physical phenomena responsible for
flowslide ...
Stable Isotope Systematics of Coalbed Gas during Desorption and Production
Geosciences (Switzerland) - Tập 7 Số 2 - Trang 43
The stable carbon isotope ratios of coalbed methane (CBM) demonstrate diagnostic
changes that systematically vary with production and desorption times. These
shifts can provide decisive, predictive information on the behaviour and
potential performance of CBM operations. Samples from producing CBM wells show a
general depletion in 13C-methane with increasing production times and
corresponding shif...
Geochemical Signatures of Paleoclimate Changes in the Sediment Cores from the Gloria and Snorri Drifts (Northwest Atlantic) over the Holocene-Mid Pleistocene
Geosciences (Switzerland) - Tập 9 Số 10 - Trang 432
A multiproxy study of the sediment cores taken from the Snorri Drift, formed
under the influence of the Iceland–Scotland bottom contour current, and from the
Gloria Drift, located southward Greenland at the boundary of Irminger and
Labrador Seas, was performed. This area undergoes a variable mixing of polar
waters with the warm North Atlantic current, whose intensity and direction
seemed to change...
Geotourism at the Natural Park of La Garrotxa Volcanic Zone (Catalonia, Spain): Impact, Viability, and Sustainability
Geosciences (Switzerland) - Tập 8 Số 8 - Trang 295
La Garrotxa Volcanic Zone is a suitable case study to analyze the impact and
sustainability of geotourism on a protected volcanic field, as it has allowed
the transformation of a poorly known territory into one of the best known and
most visited geosites of Catalonia (Spain). The protection of this volcanic area
represented the end of legal and illegal quarrying activities that significantly
damag...
Geo-Hazard-Based Approach for the Estimation of Seismic Vulnerability and Damage Scenarios of the Old City of Senerchia (Avellino, Italy)
Geosciences (Switzerland) - Tập 9 Số 2 - Trang 59
The large-scale seismic risk assessment is a crucial point for safeguarding
people and planning adequate mitigation plans in urban areas. The current
research work aims at analysing a sector of the historic centre of Senerchia,
located in the province of Avellino, in order to assess the seismic
vulnerability and damage of old masonry building compounds. First, the
typological classification of the...
Historical Monitoring of Shoreline Changes in the Cua Dai Estuary, Central Vietnam Using Multi-Temporal Remote Sensing Data
Geosciences (Switzerland) - Tập 7 Số 3 - Trang 72 - 2017
Cua Dai is one of the major estuarine areas in Central Vietnam that plays a
significant role in local maritime transport, fisheries, and tourism activities.
This paper presents a study that monitored the shoreline dynamics of the Cua Dai
estuary over a period of 50 years (1964–2014) by using field survey data,
geographic information systems techniques, and multi-temporal satellite remote
sensing i...
