Cari koleksi dengan cepat sesuai kebutuhan Anda.The 1000-km-long left-lateral Dead Sea fault is a major tectonic structure of the oriental Mediterranean basin, bounding the Arabian Plate to the west. The fault is located in a region with an exceptionally long and rich historical record, allowing to document historical seismicity catalogues with unprecedented level of details. However, if the earthquake time series is well documented, locatio…
Functional trait diversity relates variation in the structure of biological communities to function and ecosystem processes. Zooplankton occupy a central position in marine food webs, modulating energy availability to higher trophic levels, while themselves affected by environmental variation. The use of traits with functional diversity potentially enables a more mechanistic understanding of v…
We discuss an inverse source formulation aimed at focusing wave energy produced by ground surface sources to target subsurface poroelastic formations. The intent of the focusing is to facilitate or enhance the mobility of oil entrapped within the target formation. The underlying forwardwave propagation problem is cast in two spatial dimensions for a heterogeneous poroelastic target embedded wit…
FlowCAM was assessed as a tool for studying small (80–1000 mm) metazooplankton communities by comparing the abundances estimated using FlowCAM with those estimated using a stereomicroscope for eight groups of organisms. With the exception of poecilostomatoid copepods, estimates of the number of organisms in samples using FlowCAM were similar to those using the stereomicroscope. These results …
The distribution of interevent times between two successive earthquakes is generally modelled as Gamma distribution. However, significant deviations from Gamma distribution have been observed at small interevent times. These deviations can be easily modelled through the introduction of a new parameter in the interevent time distribution. The log-likelihood estimations of the model parameters pe…
We interpreted the TRIDENT satellite derived gravity field to provide detailed insights into the spatial distribution of the crustal density structures in the area of the Yellow Sea. We used 3-D forward density modelling for the interpretation that incorporated constraints from existing geological and geophysical information. A gravity stripping method is used to separate out the gravity effect…
We imaged the azimuthal anisotropy of Rayleigh wave phase velocity (10–60 s) in northeast North China Craton using the teleseismic data recorded by a dense temporary array, and then inverted for the 3-D azimuthal anisotropy of the crust and uppermost mantle (20–110 km). The results reveal that the azimuthal anisotropy varies both horizontally and vertically. Obvious stratified azimuthal ani…
Plankton fractions from a saline lake in Argentina were studied using a combined trophic marker approach. A strong seasonality of biomarkers was characteristic for the different fractions, particularly the variations in the 18:4(n 2 3) and 20:4(n 2 3) fatty acids and the d13C values. The primary production in the lake was mainly driven by diatoms, reflected by the close relation of d13C, chloro…
Processes governing productivity at the base of the pelagic food web of the southern Indian Ocean are influenced primarily by physical–chemical conditions with implications for the structure and function of the entire pelagic food web. Here, we report observations along a great circle transect from Cape Town, South Africa, to Broome in north western Australia. Primary production was tightly …
