To reconstruct the deep-water circulation for the last 3.5 Ma from deep-sea sediments of the eastern equatorial Atlantic, sea floor morphology, sub-bottom reflectors and the echo character have been mapped on the basis of 3.5 kHz records and sediment cores. Physical properties of sediments and synthetic seismograms derived from them enable us to decipher reflector sequences in environments of pelagic, current-resuspended and turbidity sedimentation. The individual reflectors originate from carbonate dissolution, hiatus, coarse sand layers and interferences. Those which are related to carbonate dissolution and hiatus provide evidence of water-mass boundaries by their distribution. Five phases of different deep-water circulation can be seen in the record of th elast 3.5 Ma, and these are related to climate history: 1. Between 3.7 Ma and 2.2 Ma a strong deep-water circulation indicates a northward flow of bottom water below 4200 m (AABW = Antarctic-Bottom Water) and a southward flow of deep-water above 4200 m (NADW = North-Atlantic Deep Water). 2. Between 1.6 and 1.4 Ma a southward flow of bottom water below 4500 m and a diminished southward flow above 4500 m can be detected. This water-mass geometry can be interpreted by an expansion of the NADW-masses and a displacement of the AABW-masses during the same time. 3. Since 1.4 Ma a northward flow of a bottom-water current developed again. This current flow created a leeside sediment ridge in the southern part of the Kane Gap and furrows in the northern part of it. 4. Between 400,000 and 200,000 yrs B. P. the oceanic and atmospheric circulation increased. The strengthened oceanic circulation caused and increase in carbonate dissolution, which is documented by a traceable reflector from 2800 m to 4500 m water depth. At the same time an increase of the atmospheric circulation caused a drastic rise in the pelagic sediment accumulation (> 100 %) through an intensification of upwelling. This runs parallel with a higher oceanic productivity in the northern equatorial divergence zone and an enhanced supply of fluvial and probably eolian sediments from the Senegal and Guinea. 5. Before 10,000 yrs B. P. an erosive northward flowing bottom-water current prevailed below 4500 m water depth. After 10,000 yrs B.P. the bottom-water flow was sluggish and non erosive.

We present time series of export productivity proxy data including 230Thex-normalized deposition rates (rain rates) of 10Be, dissolution-corrected biogenic Ba, and biogenic opal as well as authigenic U concentrations which are complemented by rain rates of total (detrital) Fe and sea ice indicating diatom abundances from five sediment cores across the Atlantic sector of the Southern Ocean covering the past 150,000 years. The results suggest that 10Be rain rates and authigenic U concentration cannot serve as quantitative paleoproductivity proxies because they have also been influenced by detrital particle fluxes in the case of 10Be and bulk sedimentation rates (sediment focussing) and deep water oxygenation in the case of U. The combined results of the remaining productivity proxies of this study (rain rates of biogenic opal and biogenic Ba in those sections without authigenic U) and other previously published proxy data from the Southern Ocean (231Pa/230Th and nitrogen isotopes) suggest that a combination of sea ice cover, shallow remineralization depth, and stratification of the glacial water column south of the present position of the Antarctic Polar Front and possibly Fe fertilization north of it have been the main controlling factors of export paleoproductivity in the Southern Ocean over the last 150,000 years. An overall glacial increase of export paleoproductivity is not supported by the data, implying that bioproductivity variations in the Southern Ocean are unlikely to have contributed to the major glacial atmospheric CO2 drawdown observed in ice cores.

"The Itinerary now reprinted in full for the first time since its publication was 'printed by John Beale, dwelling in Aldersgate street', in 1617 ... The book was first written in Latin and then translated into English ... the Latin version, however, was never printed. In 'the table' of the Itinerary, after the contents of the fourth book of the third part there is given a brief summary of twenty-five chapters ... The ms. of these chapters, which were not printed by Moryson, is now in the library of Corpus Christi college, Oxford, and portions of it were edited by Mr. Charles Hughes and published in 1903 under the title of 'Shakespeare's Europe'."--Publishers' note.

1st report never published by the state; an extract from it is given in the Transactions of the Geological Society of Pennsylvania, v. 1, p. 240-243. A brief summary of the 2d report was published in the Tennessee House journal for 1833, p. 303-305. A 10th report was presented to the House in 1850 and printed, but no copy of it can now be found.--cf. L.C. Glenn, in American geologist, v. 35, no. 2, p. 82-89.

Preface by the editor contains this statement: "Several years since there was what purported to be a translation published in London; but this was a disgraceful imposture. Mrs. Austin speaks of it as the most flagrant piece of literary dishonesty on record, not without justice; and Mr. Carlyle refers to it much in the same spirit. It was a poor copy of a wretched French version, in which frequently twenty pages of the original are omitted at a time, and hardly a sentence is rendered with fidelity." This refers to an anonymous translation published in 2 vols., London, 1824, and reprinted in 1 vol., New York, 1824 and 1844. cf. Characteristics of Goethe. From the German of Falk, von Müller, etc., with notes ... by S. Austin, vol. II (1833) p. 129, and Carlyle's Crit. and miscell. essays, New York, 1872, vol. I, p. 178.
