A remote sensing based monitoring system for discrimination between climate and human-induced vegetation change in Central Asia
(Management of Environmental Quality: An International Journal, 2008)Purpose – This paper aims to demonstrate the importance of taking into account precipitation and the vegetation response to it when trying to analyse changes of vegetation cover in drylands with high inter-annual rainfall ... -
A review of air–ice chemical and physical interactions (AICI): liquids, quasi-liquids, and solids in snow
(Atmospheric Chemistry and Physics, 2014)Snow in the environment acts as a host to rich chemistry and provides a matrix for physical exchange of contaminants within the ecosystem. The goal of this review is to summarise the current state of knowledge of ... -
A review of the ecosystem functions in oil palm plantations, using forests as a reference system
; ; ; ; ; ; ;
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Biological Reviews, 2016)
Oil palm plantations have expanded rapidly in recent decades. This large-scale land-use change has had great ecological, economic, and social impacts on both the areas converted to oil palm and their surroundings. However, ... -
A Review on Photothermal Conversion of Solar Energy with Nanomaterials and Nanostructures: From Fundamentals to Applications
(Advanced Sustainable Systems, 2022-07-06)Solar energy is a green, sustainable, and de facto inexhaustible energy source for mankind. The conversion of solar energy into other forms of energy has attracted extensive research interest due to climate change and the ... -
A review on risk assessment in managed aquifer recharge
; ; ; ; ; (Integrated Environmental Assessment and Management, 2022-02-23)
Managed aquifer recharge (MAR) refers to a suite of methods that is increasingly being applied worldwide for sustainable groundwater management to tackle drinking or irrigation water shortage or to restore and maintain ... -
A robust potential-based contact force solution approach for discontinuous deformation analysis of irregular convex polygonal block/particle systems
;; ; ; (Acta Geotechnica, 2020-07-27)
Contact interaction of two bodies can be modeled using the penalty function approach while its accuracy and robustness are directly associated with the geometry of contact bodies. Particularly, in the research fields of ... -
A seamless filter for daily to seasonal forecasts, with applications to Iran and Brazil
(Quarterly Journal of the Royal Meteorological Society, 2019)
A digital filter is introduced which treats the problem of predictability versus time averaging in a continuous, seamless manner. This seamless filter (SF) is characterized by a unique smoothing rule that determines the ... -
A Seismic Approach to Flood Detection and Characterization in Upland Catchments
; ; ; ; (Geophysical Research Letters, 2022-10-17)
About 10% of Europe's surface area is prone to rapid flooding of rivers confined in valleys. The devastating potential of such floods is exacerbated by the deficits of existing gauging networks, including low station ... -
A seismic monitoring approach to detect and quantify river sediment mobilization by steelhead redd-building activity
; ; ; (Earth Surface Processes and Landforms, 2020)
The role of spawning salmonids in altering river bed morphology and sediment transport is significant, yet poorly understood. This is due, in large part, to limitations in monitoring the redd-building process in a continuous ... -
A site formation model for Cuncaicha rock shelter: Depositional and postdepositional processes at the high‐altitude keysite in the Peruvian Andes
; ; (Geoarchaeology, 2021-11-14)
We report results from geoarchaeological investigations at Cuncaicha rock shelter (4480 m above sea level) in the high Andes of southern Peru. Using field observations, geomorphological, micromorphological, micro‐Fourier ... -
A small podocnemidoid (Pleurodira, Pelomedusoides) from the Late Cretaceous of Brazil, and the innervation and carotid circulation of side‐necked turtles
; Iori, Fabiano V.; ; ; (Papers in Palaeontology, 2020-02-12)
Pleurodires are less diverse than cryptodires, together forming the two major lineages of crown turtles. Their fossil record, however, is rich. A particularly large number of fossil pleurodires, many belonging to the ... -
A Snapshot on the Buildup of the Stable Water Isotopic Signal in the Upper Snowpack at EastGRIP on the Greenland Ice Sheet
; ; ; ; ; (Journal of Geophysical Research: Earth Surface, 2023-02-22)
The stable water isotopic composition in firn and ice cores provides valuable information on past climatic conditions. Because of uneven accumulation and post‐depositional modifications on local spatial scales up to hundreds ... -
A Spectrally Consistent Globally Defined Geodetic Mean Dynamic Ocean Topography
(Journal of Geophysical Research: Oceans, 2020)
The space-borne geodetic temporal mean dynamic topography (MDT) is obtained from the difference of altimetric mean sea surface (MSS) h and the geoid height N. With the geostrophic surface currents obtained from its gradient, ... -
A staging system for Atlantic herring (Clupea harengus) larvae based on external morphology and skeletal development
; ; ; ; (Limnology and Oceanography: Methods, 2023-05-26)
Abstract Atlantic herring (
Clupea harengus ) plays a key role within ... -
A starfish bed in the Middle Miocene Grand Bay Formation of Carriacou, The Grenadines (West Indies)
(Geological Magazine, 2013)The first starfish bed to be recognized from the Antilles is a lensoid body in the middle Miocene Grand Bay Formation of Carriacou, The Grenadines (West Indies). This unit was deposited in a turbidite basin in a region ... -
A statistical analysis of time trends in atmospheric ethane
; ; ; ; ; ; ; ; (Climatic Change, 2020-08-27)
Ethane is the most abundant non-methane hydrocarbon in the Earth’s atmosphere and an important precursor of tropospheric ozone through various chemical pathways. Ethane is also an indirect greenhouse gas (global warming ... -
A Statistical Classifier for Historical Geomagnetic Storm Drivers Derived Solely From Ground-Based Magnetic Field Measurements
; ; ; (Earth and Space Science, 2019)
Solar wind observations show that geomagnetic storms are mainly driven by interplanetary coronal mass ejections (ICMEs) and corotating or stream interaction regions (C/SIRs). We present a binary classifier that assigns one ... -
A stochastic fractal model of the universe related to the fractional Laplacian
(WIAS, Berlin2008)
A new stochastic fractal model based on a fractional Laplace equation is developed. Exact representation for the spectral and correlation functions under random boundary excitation are obtained. Randomized spectral expansion ... -
A Stochastic Representation of Temperature Fluctuations Induced by Mesoscale Gravity Waves
