AmasSeds Project

A historical perspective of the primary research that has shaped our current understanding of Amazon shelf biogeochemistry is presented initially as an overview. The primary focus of the chapter, however, is on biogeochemical cycles and related insights that have been developed during the past 5 years, many of which have come from the recendy completed AmasSeds Project (see Nittrouer and DeMaster 1996, for overview). 

The Amazon shelf nutrient budgets for Si, P, and N are shown in Fig. 17.3 and Table 17.2. These data emphasize the most recent results from the AmasSeds Project (for example, DeMaster et al. 1996, DeMaster and Pope 1996 Aller et al. 1996), as well as a previous compilation by Richey et al. (199D-The gross uptake rates for Si, P, and N were estimated based on the seasonal C primary productivity data of Smith and DeMaster (1996), assuming stoichiometric Redfield C/N (6.6 on a molar basis) and C/P (IO6) ratios (Redfield et al. 1963). A C/Si mole ratio of 6.6 was used for tropical diatoms (Brzezinski 1985). Shoreward advection of ocean water originated from subsurface... 

Within a year of his return to Louisiana, Rillieux realized that he would have to finance his project himself or attract investors. During the next decade, he tried both. He convinced several planters to let him build and test his equipment in their sugarhouses, but each time his locally built machinery failed. He amassed an enormous fortune in land speculation and then lost it in a bank failure. At one point, he offered to spend 50,000 of his own money to build his system on the plantation of A. Durnford, a rich free man of color whose patron was the eccentric white founder of Liberia. Durnford refused the offer because he did not want to give up control of his people, i.e., his 75 slaves. 

Holmes concludes, perhaps with as much self-congratulation as contrition, Peace be upon thee, Israel 29 In The Ambivalent Image, her study of Jews in American cultural imagery, Louise Mayo has amassed an invaluable compendium of racial figures of Jewishness across time. Although Mayo s project did not entail... 

The term virtuoso was used for wealthy patrons of natural philosophy who enthusiastically undertook miscellaneous projects, without rigor or training. Indiscriminate hoarders and collectors of anything and everything, the virtuosi amassed private museums or cabinets (Haynes 1994, pp. 35 9). 

FIGURE 10.16 Fresnel representation of the director of a constant phase element (left) and of amass transfer (right). The angle of the director is the phase angle and its two projections on the orthogonal axes give the amount of conservation (vertically) and the amount of dissipation (horizontally).
