The flow of terrestrial groundwater to the sea is an important natural component of the hydrological cycle. This process, however, does not explain the large volumes of low-salinity groundwater that are found below continental shelves. There is mounting evidence for the global occurrence of offshore fresh and brackish groundwater reserves. The potential use(More)
The use of hydraulic head measurements in ground water of variable density is considerably more complicated than for the case of constant-density ground water. A theoretical framework for dealing with these complications does exist in the current literature but suffers from a lack of awareness among many hydrogeologists. When corrections for density(More)
[1] In the present paper it is shown how profiles consisting of closely spaced ( 10 m) temperature measurements at shallow depth, obtained at several instances during one season, provide a detailed record of lateral variations in vertical groundwater flow. This is illustrated by a field study around the Peel Boundary Fault zone that cuts through the(More)
Pre-operative serum CA 125 levels were elevated (greater than 35 U/ml) in 44 of 46 (96%) patients with epithelial ovarian cancer. Their serum CA 125 levels ranged from 36 to 8670 U/ml and a correlation with tumour stage was found. Also, during progressive disease, 49 of 53 patients showed elevated levels. At the time of second-look operations, elevated(More)
While the existence of relatively fresh groundwater sequestered within permeable, porous sediments beneath the Atlantic continental shelf of North and South America has been known for some time, these waters have never been assessed as a potential resource. This fresh water was likely emplaced during Pleistocene sea-level low stands when the shelf was(More)
[1] Two field data sets are used to model near-surface soil temperature profiles in a bare soil. It is shown that the commonly used solutions to the heat flow equations by Van Wijk perform well when applied at deeper soil layers, but result in large errors when applied to near surface layers, where more extreme variations in temperature occur. The reason(More)
[1] Using numerical models, we evaluate hydrogeological regime changes in high-latitude river basins under conditions of ground surface warming. These models describe transient heatand fluid flow coupled to the hydrogeological impacts of phase-changes from ice to liquid water. We consider an idealized unconsolidated sedimentary aquifer system in which(More)
This study was undertaken to determine whether histamine H2-receptors are involved in the regulation of gastrin secretion in man. Since previous studies on the effect of histamine H2-receptor blockade on gastrin release are conflicting, we have studied the effect of histamine infusion (130 nmol/kg/hr) with simultaneous H1-receptor blockade on gastrin(More)
