Book Description
Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas (8,848m elevation) and to the west of the deepest trench in the ocean, Philippine Trench (10,497m water depth) (Wang P. 2004). Biogeographically, the SCS belongs to the so-called “East Indies Triangle” where modern marine and terrestrial biodiversity reaches a global maximum (Briggs 1999). Among the major marginal sea basins from the west Paci?c, the SCS presents some of the best conditions for accumulating complete paleoclimatic records in its hemipelagic deposits. These records are favorable for high-resolution pa- oceanographic studies because of high sedimentation rates and good carbonate preservation. It may not be merely a coincidence that two cores from the southern 14 SCS were among the ?rst several cores in the world ocean used by AMS C dating for high-resolution stratigraphy (Andree et al. 1986; Broecker et al. 1988).
The South Atlantic
Author: Gerold WeferPublisher: Springer Science & Business Media
ISBN: 3642803539
Category : Science
Languages : en
Pages : 815
Book Description
The book presents results of recent projects in oceanography and marine geosciences (e.g. WOCE, JGOFS, PAGES, ODP) regarding present and past circulation in the South Atlantic. The objective of the book is to integrate results from both oceanographic and geological studies. As the connecting link between the Antarctic and the North Atlantic, the South Atlantic plays a crucial role with regard to the heat budget of the North Atlantic and to the biogeochemical budget of the global ocean. New results from studies of meridional water mass and heat transports are presented. The central theme of geological investigations is the reconstruction of current and productivity systems in the South Atlantic during the late Quaternary.

River-Dominated Shelf Sediments of East Asian Seas
Author: P.D. CliftPublisher: Geological Society of London
ISBN: 1862397406
Category : Science
Languages : en
Pages : 269
Book Description
The rivers of East Asia are some of the largest and most important to human society and the global economy. They drain a variety of terrains from the Tibetan plateau, the hill country of southern China and the steep mountains of Taiwan. The sediment they carry potentially records the longterm evolution of continental environments within the marine stratigraphic record. Sediments reaching the ocean have to traverse the wide continental shelves where they may be reworked and transported by longshore currents, typhoon storm waves, as well as large ocean currents such as the Kuroshio. Deciphering any marine record requires us to understand the dynamics of sediment transport on the continental shelves, and this region acts as a global type example of such processes. Studies in this volume span a wide range of subdisciplines in the marine sciences and provide new insights into how sediment is distributed offshore after leaving the river mouths

Late Quaternary Changes in the Oceanography of the Eastern Tropical Pacific

Book Description
Factor analysis of radiolarian species from the tops of 34 gravity cores in the area extending from 5°N to 45°N, 95°W to 155°W, yields five factor assemblages which are related to the present surface circulation: 1) a Pacific Equatorial Water assemblage; 2) a California Current assemblage; 3) a North Equatorial Current assemblage; 4) a Tropical Surface Water assemblage; 5) an oxygen minimum layer assemblage. A sixth assemblage appears to be the result of dissolution. The variation of these factors through the late Pleistocene is based on the analysis of samples from two cores. Transfer functions which relate core top assemblages to temperature at the sea surface and at 130 m depth were used to determine paleotemperatures. Stratigraphic control was provided by oxygen isotope analysis of planktonic foraminifera from one core, Synchronous levels in the other core were determined from biostratigraphic correlation of the variations in the abundance of three species of radiolaria between cores. A reconstruction of the paleoceanography based on the results of the above analyses indicates that during the last glacial maximum (18,000 yrs BP): 1) sea surface temperatures were slightly lower than today; 2) the areal extent of warm Pacific Equatorial water and Tropical Surface water was diminished; 3) the California Current, North Equatorial Current, and the Equatorial Current were stronger than at present; 4) there was an increase in the thermal gradient in the thermocline and/or an increase in the depth of the mixed layer; 5) air and sea surface circulation patterns were constricted and experienced minimal north-south oscillation.
