The quality of shallow groundwater in the rural Bourtanger Moor area (NW Germany) has significantly deteriorated because of input of agricultural nutrients and by acid rain. This potentially endangers the local water supply from wells screened in dee

Forty‐four sediment samples and 23 Mn crusts and Mn nodules have been analyzed for several elements in order to characterize their geochemical nature. Most of the Mn crusts and Mn nodules are of hydrogenous origin, although one crust (U375) from th

Fifty analyses of rare earth elements as well as mineralogical studies have been carried out on a suite of manganese nodules and crusts from the Central Indian Basin and the Western Indian Ocean. The aim was to identify the processes controlling the

Rare earth and other trace elements in manganese nodules, micronodules and surface sediments from a transect in the Southwestern Pacific Basin at 42°S were determined by instrumental neutron activation analysis. The data include analyses of 23 manga

Fourteen manganese nodules and three ferromanganese crusts from the Indian Ocean were analysed for major and minor elements and the 14 naturally occurring rare earth elements (REE). The REE were analysed by inductively coupled plasma-mass spectroscop
