Congo River

Impractical Not at all. John Goddard has accomplished more than a hundred of his original 127 goals. He s become one of the most famous explorers in the world. Goddard is the first man in human history to explore the entire length of both the Nile and Congo rivers.

Fig. 3.8 A manganese profile in pore water of sediments off the Congo River estuary, in a water depth of approx. 4000 m. The profile is, in principle, quite similar to the profile of nitrate previously shown in Figure 3.7. Here, manganese is released into the pore water at a specific depth below the sediment surface. A gradient with a high negative slope leads most of the Mn upwards another gradient, positive and more level, conveys manganese into a precipitation zone, which was just included in the lowest core meter (between 14 and 15 m).

Fig. 3.26 In situ measurement of an oxygen profile in a water depth of 3100 m, off the mouth of the Congo River. The microelectrode detected an open cavity flooded with oxygen-rich bottom water in a depth between 80 mm and 90 mm below the sediment surface (after Glud et al. 1994).

Fig. 4.15 Carbon stable isotope data in different compartments of a continental margin settings with the Congo Fan as an example. Data for 5 C values of biota and sediments are from measurements in the Congo Fan and the Congo River catchment area (Mariotti et al. 1991, Muller et al. 1994, Muzuka 1999, Schwartz et al. 1986, Westerhausen et al. 1993).

Fig. 7.2 Dissolved iron concentrations of surface water from a transect off the Congo River towards the open ocean. Pore sizes of 1.2, 0.45, 0.22, 0.05 and 0.025 Um (according to graphs from above downward) were used to separate particulate from dissolved phase (adopted from Figueres et al. 1978).

Fig. 15.8 Geochemical data obtained from a sediment core originating from a depth a 4,000 m off the Congo-River estuary (GeoB1401, GeoB4914) (Zabel and Schulz 2001). Left concentration and isotope stages. Center Sulfate...

Another source of future phosphate production is offr shore deposits, Deposits of this type occur along the southeastern coast of the United States, on the Feru-Chile shelf, offshore Namibia, on the Chatham Rise off New Zealand, offshore Baja California, Mexico, and off the Congo River delta. At the present time, none of these offshore deposits are mined, and they probably...
