Atlantic Ocean isotopic abundances

More recently, JickeUs et al. (2003) measured the isotopic abundance of aerosols from the North and South Atlantic Ocean. They found a positive correlation between NH4 aerosol concentrations and ofNH and concluded that the... 

Figure 13 Nd abundance versus (a) salinity and (b) silicate in deep seawater. Nd concentrations do not show the same well-behaved characteristics as Nd-isotope ratios with salinity and silicate in global deep water. Mixing envelopes are shown between North Atlantic and Pacific end-members, and the circum-Antarctic, South Atlantic, and Indian Ocean samples fall outside of it. Plotted data are from >2,500 mb si, except two Drake Passage data from 1,900 m and 2,000 m (Nd data sources Piepgras and Wasserburg, 1980, 1982, 1983, 1987 Spivack and Wasserburg, 1988 Piepgras and Jacobsen, 1988 Bertram and Elderfield, 1993 Jeandel, 1993 Shimizu et al., 1994 Jeandel et ah, 1998). Where salinity or silicate were not available in the publication, they were estimated from Levitus (1994),...
