    Notes: [Auszug] LIGHTY ET AL. REPLY-The points raised by Braithwaite have been discussed in several studies of Caribbean Holocene reefs. As mentioned in our letter1, for example, core data from a relict reef (depth 18m) off southeastern St Croix indicated that a flourishing, shallow-water Acropora palmata ...

    Notes: [Auszug] Five distinct fades4 were identified from samples obtained during excavation of a ditch (3 m wide, 450 m long, maximum depth 11 m) perpendicular to the trend of this shelf-edge feature: (1) back-reef coral head; (2) back-reef A. cervicornis (Lamarck); (3) A. palmata; (4) fore-reef coral head; and ...

    Notes: [Auszug] The relationship between sedimentation and tectonics in island arc settings is a close one but remains poorly understood. A sedimentological investigation of the western Hellenic Trench has revealed some of the highest sedimentation rates measured in the Mediterranean Sea. The complex structural ...

    Notes: [Auszug] LIGHTY ETAL. REPLY-In our report1, we attributed the demise of the shelf-edge Acropora palmata (Lamarck) barrier reef off south-east Florida to periods of extensive turbidity and to pronounced decreases in water temperatures during the first flooding of large, relatively flat areas of the shelf by ...

    Notes: [Auszug] THE reliability of the carbon-14 method of dating was admirably demonstrated initially by W. F. Libby1 with a series of measurements of samples of known age. These afforded confirmation of the basic assumptions of the method with an accuracy of approximately 10 per cent. Now, eleven years later, ...

    Notes: [Auszug] The closed Alexandersfontein depression, now only an evaporation pan, harboured a +19 m lake with a surface area of 44 km2 and Middle Stone Age occupance, a little before 16,000 BP. Assuming a temperature depression of 6° C, calculations show that rainfall was about ...

    Description: The southernmost part of the Sohm Abyssal Plain in the Northwest Atlantic Basin is geographically distal with respect to the major source of Quaternary terrigenous material transported from the Canadian Maritime Provinces. An assessment of the proportion of more locally introduced sediment relative to that derived from distal sources is based largely on size and compositional analyses of Quaternary piston core samples. These data are supplemented by radiocarbon dating of selected core samples, bottom photographs, conductivity-temperature-depth profiles, and seismic records. The premises of the study are that (a) locally derived sediment should be most abundant near high-relief bathymetric features such as seamounts and abyssal hills, and (b) such material should contain enhanced proportions of reworked volcanic debris and alteration products. Core analyses reveal that the amounts of these are directly related to proximity of volcanic ocean-bottom features, and that a significant, although not total, amount of such volcanic materials recovered from cores are derived from submarine weathering of basalt. Associated with this assemblage are nannofossils, dating from the Quaternary to the Upper Cretaceous, reworked from older strata. This increased proportion of volcanic and related products and reworked faunas near seamounts and basement rises strongly implies that such topographic features continue to serve as major source terrains. Locally derived volcanic materials, however, are usually disseminated and masked on the Sohm Abyssal Plain, particularly in sectors receiving large amounts of terrigenous turbidites and biogenic suspensates, and/or undergoing reworking by bottom currents. We propose that the volcanic fraction can serve as a useful index, or "yardstick," to interpret the role of locally derived material in abyssal plain sedimentation. A sedimentation model is developed to illustrate the premise that as access to land-derived sources diminishes, the proportion of terrigenous components is reduced while pelagic and volcanic fractions are enhanced. Thus, sediment accumulating in abyssal plains almost totally isolated from terrigenous sources would comprise significant amounts of pelagic (including wind-blown) and volcanic components.
