Two piston cores (PCs), containing two full glacial cycles, were retrieved at Murray Ridge. One core (PC463) contains sediment deposited at 920 mbsl within, the other (PC464) has sediment deposited at 1470 mbsl below the current oxygen minimum zone,

To quantify and explain the contributions by pollution and chemical weathering to their composition, we studied the chemistries of springs and surface waters in the mountainous part of the Vouga River basin. Water samples were collected during a numb

Madeira island consists of Miocene to Pleistocene lavas and pyroclasts. Major rock types are alkali-basalts, basanites and hawaiites; principal soil types are leptosols, andosols and cambisols. Our main objective was to link the chemistry of ground w

The redox status of subsurface aqueous systems is controlled by the reactivity of solid redox-sensitive species and by the inflow of such species dissolved in groundwater. The reactivity toward molecular oxygen (O2) of solid reductants present in thr

Normalization of trace element contents of sediment through division by the content of an immobile element – usually aluminum – is common practice in marine geochemical studies. This might appear to be a simple way of correcting for dilution by s

Box cores of sediments were collected at eight stations along a NE–SW transect starting on the Pakistan continental slope in the moderately productive northeastern sector of the Arabian Sea, via Murray Ridge to the highly productive upwelling zone

The presence of a strongly developed oxygen minimum zone (OMZ; [O 2 ] 2+ and Fe 2+ show that reduction of manganese and iron oxides plays a minor role in sediments lying within the OMZ and a larger role in sediments lying below the OMZ.

Three well-developed 10 Ma old sapropels from the island of Gavdos (Greece) were selected for a detailed geochemical, micropaleontological and sedimentological study. The sapropels are characterized by a high organic carbon and a low carbonate conten

Using a combination of a grouping algorithm and a geochemical mole balance algorithm, we could identify and quantify the contributions made by water-rock and water-biomass interactions to the composition of shallow groundwaters in northern Portugal,

In order to update the geohydrologic characterisation of Chaves geothermal area, coupled isotopic and chemical studies have been carried out on hot and cold CO2-rich mineral waters discharging, in northern Portugal, along one of the major regional NN
