Assessment of the Relationship between Passages of Tropical Cyclones and their Origins of Genesis for Managing Risk of the Coast of Bangladesh
Published: 2023-05-26
Subjects: Physical Sciences and Mathematics
To understand risk from upcoming tropical cyclones (TCs) of Bangladesh, Impact of Indian Ocean Dipole (IOD) on origins of TCs genesis historically over Bay of Bengal (BoB) should be considered. So, the correlation between Dipole Mode Indexes (DMI) and frequencies of TCs generated in BoB has been investigated for (1877-2018) era. Changes in decade-wise mean DMI have been found linearly correlated [...]
Germany-wide time series of interpolated phenological observations of main crop types between 1993 and 2021
Published: 2023-05-26
Subjects: Physical Sciences and Mathematics
The data descriptor represents a Germany-wide and spatio-temporally consistent 1 x1 km² analysis-ready time series of interpolated days of the year (DOYs). The data set covers 56 entry dates of phenological development stages of 9 main crop types for the period between 1993 and 2021. The derivation of the 1624 records is based on phenological observations provided by German Meteorological [...]
Chasing the water table: The impact of groundwater depletion on rural drinking water supply in peninsular India
Published: 2023-05-25
Subjects: Civil and Environmental Engineering
Groundwater overexploitation has been cited as one of the biggest threats to rural drinking water in India, but there is very little quantitative evidence. In this paper, we aim to understand (1) the extent of actual groundwater depletion and its impact on rural drinking water supply systems, (2) the primary driver of groundwater depletion and (3) the additional financial burden in finding new [...]
Evolution of lake surface temperatures of high-altitude lakes in the European Alpine region under climate change
Published: 2023-05-25
Subjects: Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Lake Surface Temperature (LST) is a key characteristic that reflects meteorological and climatological influences on lakes. In general, there is limited LST data from high elevation lakes available as these areas are remote and not part of regular monitoring programs. Nonetheless, it is crucial to understand their response to climate warming for the development of effective management strategies [...]
Macroplastic fragmentation in rivers
Published: 2023-05-25
Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Geomorphology, Hydrology, Other Earth Sciences, Other Environmental Sciences, Sedimentology
The process of macroplastic (>0.5 cm) fragmentation results in the production of smaller plastic particles (micro- and nanoplastics), which threaten biota and human health and are difficult to remove from the environment. The global coverage and long retention times of macroplastic waste in fluvial systems (ranging from years to centuries) create long-lasting and widespread potential for its [...]
Integrated Formation Attenuation and Multiple Generator Identification from Multi-well VSP Data
Published: 2023-05-25
Subjects: Geophysics and Seismology
The Vertical Seismic Profile (VSP) is a widely used technique for extracting velocity information and seismic well tie purposes. However, the full potential of VSP data remains underutilized. This study explores the broader applicability of VSP data beyond its conventional usage by investigating its benefits for seismic data processing and interpretation. Advanced VSP products, incorporating [...]
Salt‑rich versus salt‑poor structural scenarios in the central Northern Calcareous Alps: implications for the Hallstatt facies and early Alpine tectonic evolution (Eastern Alps, Austria)
Published: 2023-05-25
Subjects: Other Earth Sciences, Sedimentology, Tectonics and Structure
One of the most remarkable features of the central Northern Calcareous Alps (Eastern Alps, Austria) is the widespread presence of Upper Triassic deep-water carbonates (the Hallstatt facies) and Permo-Triassic evaporites resting on deep-water Middle Jurassic strata and their underlying Upper Triassic shallow-water carbonate platform successions. The Hallstatt facies and accompanying evaporites [...]
Maxar’s WorldView-3 Enables Low-Concentration Methane Detection from Space
Published: 2023-05-25
Subjects: Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology
Methane is large contributor to climate change; for this reason, detecting and eliminating sources of methane emissions is a key element to minimizing the effects of on-going climate change. While there are a variety of methods currently used to detect methane emissions, ranging from ground-based sensors to aerial sensors like drones and aircraft, satellite detections provide a broad-area [...]
The role of thermal notch erosion in forcing localised calving failure and short-term increases in velocity at a lake-terminating glacier in southeast Iceland
Published: 2023-05-25
Subjects: Glaciology
We utilised repeat high-resolution UAV-SfM surveys, alongside terrestrial photography acquired in-situ, to investigate, for the first time, the role of thermal notch erosion in forcing localised calving failure and subsequent short-term increases in velocity at a lake-terminating glacier. This data was acquired daily (where possible) across one week in July 2019 and two weeks in July 2021 to [...]
Linking 3D long-term slow-slip cycle models with rupture dynamics: the nucleation of the 2014 Mw 7.3 Guerrero, Mexico earthquake
Published: 2023-05-25
Subjects: Geophysics and Seismology
Slow slip events (SSEs) have been observed in spatial and temporal proximity to megathrust earthquakes in various subduction zones, including the 2014 $M_\mathrm{w}$7.3 Guerrero, Mexico earthquake which was preceded by a $M_\mathrm{w}$ 7.6 SSE. However, the underlying physics connecting SSEs to earthquakes remains elusive. Here, we link 3D slow-slip cycle models with dynamic rupture simulations [...]
Global mean sea level higher than present during the Holocene
Published: 2023-05-24
Subjects: Earth Sciences, Other Earth Sciences, Physical Sciences and Mathematics
Global mean sea-level (GMSL) change can provide insight on how ice sheets, glaciers, and oceans respond to warming[1;2]. The Holocene (11.7 ka to present) marks a time when temperatures may have exceeded early industrial (1850 CE) values[3]. Evidence from Greenland[4] and Antarctica[5;6] indicates that both ice sheets retreated inland of their present-day extents during the Holocene, yet previous [...]
GOES-R land surface products at Western Hemisphere eddy covariance tower locations
Published: 2023-05-24
Subjects: Earth Sciences, Environmental Sciences
The terrestrial carbon cycle varies dynamically over short periods that can be difficult to observe. Geostationary (“weather”) satellites like the Geostationary Environmental Operational Satellite - R Series (GOES-R) deliver near-hemispheric imagery at a ten-minute cadence, and its Advanced Baseline Imager (ABI) measures visible and near-infrared spectral bands that can be used to estimate land [...]
Exponential life-threatening rise of the global temperature
Published: 2023-05-23
Subjects: Atmospheric Sciences, Climate, Nature and Society Relations
Global temperatures are rising. This paper demonstrates for the first time that the global temperature increase has not been linear but is exponential with a doubling time of about 25 years. Both the amount of carbon dioxide produced by the combustion of fossil fuels and the amount of carbon dioxide in the atmosphere have also risen exponentially, with a similar doubling time. The exponential [...]
The Future in Anthropocene Science
Published: 2023-05-23
Subjects: Climate, Environmental Studies, Nature and Society Relations, Sustainability
The Anthropocene is the present time of human-caused accelerating global change, and new forms of Anthropocene risk are emerging that society has hitherto never experienced. Science and policy are grappling with the temporal and spatial magnitude of these changes, as well as the diminishing margin between science and policy itself. However, there is a gap in the transparency — and perhaps even in [...]
Developing the future visions for seamless multi-hazard warning for volcanic eruptions
Published: 2023-05-22
Subjects: Earth Sciences, Volcanology
Much work has been done to build arrangements between volcanology and meteorology to handle the aviation risks from volcanic ash. This workshop will discuss how to approach collaborative arrangements for other volcanic hazards to the public, particularly where a multi-disciplinary approach is required. These hazards include tsunamis, ashfall, rainfall-induced dome collapses, lahars, pumice, [...]
