Reactive flow at depth (either related to underground activities, like enhancement of hydrocarbon recovery andCO2 storage, or to natural flow like in hydrothermal zones) can alter fractures’ topography, which might in turn change their seismic responses. Depending on the flow and reaction rates, instability of the dissolution front can lead to a wormhole-like pronounced erosion pattern. In a …

The ctenophore Mnemiopsis leidyi is characterized by high growth rates and a large reproductive capacity. However, reproductive dynamics are not yet well understood. Here, we present laboratory data on food-dependent egg production in M. leidyi and egg hatching time and success. Further, we report on the reproduction of laboratory-reared and fieldcaught animals during starvation. Our results s…

Two lobate ctenophores, Bolinopsis infundibulum and Mnemiopsis leidyi, occur in the North Sea. Stomach contents of field-collected B. infundibulum were recorded and clearance rates for cladocerans and copepods calculated. In starvation experiments, daily body carbon losses of 2.2 and 1.2% and total carbon content losses of 76 and 63% were observed for B. infundibulum (after 68 days) and M. leid…

Carbon-specific prey clearance and ingestion rates of 1.5-mm tentaculate larvae of the ctenophore Mnemiopsis leidyi increased linearly between 6 and 258C but declined between 25 and 308C. Both absolute (length) and carbon-specific growth rate increased linearly with increasing temperature. The latter was 0.87 d21 at 258C. Extremely low or negative growth rates observed at 6 and 308C help define…

Rules of Origin (ROO) are in need of reform. Aside from being used for protectionist purposes, they have also become so complicated that they result in companies foregoing trade preferences granted by preferential agreements on a substantial scale. This article makes the argument for a fundamental reconceptualization of ROO, based on today�s Global Value Chains (GVCs). The article is divi…

Recently, various methods have been proposed and applied for earthquake source imaging, and theoretical relationships among the methods have been studied. In this study, we make a follow-up theoretical study to better understand the meanings of earthquake source imaging. For imaging problems, the point spread function (PSF) is used to describe the degree of blurring and degradation in an obtain…

Measuring zooplankton biomass and physiological rates is of paramount importance in biological oceanography in order to assess the role of this community in, e.g. carbon fluxes. Classical methods (incubations) are very time-consuming and cannot match the frequency of physical and chemical measurements. Attempting to solve this, a variety of methods (e.g. egg production, RNA/DNA ratio or enzyme…

Phronima sedentaria is a hyperiid amphipod that diel migrates into a pronounced oxygen minimum zone (OMZ) in the Eastern Tropical North Pacific. In this study, oxygen consumption and lactate production were measured in P. sedentaria to estimate the aerobic and anaerobic contributions to total metabolism under conditions that mimic its day- (1% oxygen, 108C) and night-time (20% oxygen, 208C) hab…

Viscoelastic behaviour of materials in nature is observed in post-event deformations due to seismic or volcanic activities. In this paper, by adopting the correspondence principle, we propose an inelastic model to predict first the Laplace-domain response of a transversely isotropic viscoelastic half-space due to a shear or tensile fault of polygonal shape. The displacement and stress fields i…
