The Portunid Crabs (Crustacea : Portunidae) Collected by the NAGA Expedition

Fri, 5 Jun 2009 00:00:00 +0000

Although the collections of NAGA Expedition are small and contain many well-known and widely distributed species of the Indo-West Pacific area, they also contain several little-known forms (e.g. Charybdis edwardsi Leene and Buitendijk, Portunus minutus [Shen] and P. tweediei [Shen]) and two new species. A few additional Indo-West Pacific Specimens from the collections of the Scripps Institution, other than NAGA material, are included in the present report. With the better-known species the synonymy has been abbreviated to one or two recent references which permit ready identification; in other cases a full synonymy is given. NAGA collections are reported in the text as Station Numbers (followed by NAGA Catalogue Numbers) with detailed localities and their lists of species in the Appendix. These localities are also plotted on the map. Measurements are of total breadths, including last anterolateral teeth; those over 100 mm to the nearest 0.5 mm, and the remainder to the nearest...

Gammaridean Amphipoda from the South China Sea

Fri, 5 Jun 2009 00:00:00 +0000

The NAGA Expedition conducted a program of marine investigations in the Gulf of Thailand and the South China Sea during the years 1960-1961. In connection with this program, a bottom fauna survey was made in the Bay of Nhatrang, South Viet Nam. Identifiable amphipods, representing 14 established species and 21 new species, were recovered from 97 of more than 360 stations sampled in the bay and form the basis of this paper.

Euthecosomatous Pteropods (Mollusca) in the Gulf of Thailand and the South China Sea: Seasonal Distribution and Species Associations

Thu, 25 May 2006 00:00:00 +0000

The Gulf of Thailand and the South China Sea were each sampled during five cruises of the Naga Expedition, 1959-1961. The following twenty species were present: Cavolina gibbosa, C. globulosa, C. inflexa, C. longirostris, C. uncinata, Clio recurva, C. cuspidata, C. pyramidata, Creseis acicula, C. chierchiae, C. virgula, C. bulgia, Cuvierina columnella, Diacria quadridentata, D. trispinosa, Hyalocylis striata, Limacina bulimoides, L. inflata, L. trochiformis, and Styliola subula. Distribution maps are presented for each species and variations in distribution are related to climatic and hydrographic parameters. Statistical treatment of the data helped to establish recurrent species groups among ten selected species and to relate the distribution of these groups to environmental configurations. Broadly speaking, there are two recurrent species groups. The first is restricted to the deeper-water areas of the South China Sea, while the second occurs in both the Gulf of Thailand...

The physical oceanography of the Gulf of Thailand, Naga Expedition; Bathythermograph (BT) temperature observations in the Timor sea, Naga Expedition, Cruise S11

Mon, 3 Oct 2005 00:00:00 +0000

The Research Vessel Stranger of the Scripps Institution of Oceanography, University of California, San Diego, was engaged in the Naga Expedition in the Gulf of Thailand and the South China Sea during the period of October, 1959, to December, 1960. The expedition was jointly sponsored by the Governments of South Viet Nam, Thailand and the United States of America. It had a two-fold purpose; to collect oceanographic, biological and fisheries data and material and to train scientists and technicians from Thailand and South Viet Nam in oceanography and marine biology. This report is a description of the oceanographic environment in the Gulf of Thailand derived from oceanographic and meteorological data collected for the most part on six cruises in the Gulf between October, 1959, and December, 1960. The cruise plans for the Gulf of Thailand were designed to investigate systematically the distribution and variability of the physical properties of the Gulf waters. The station plan...

Euphausiids of Southeast Asian waters

Fri, 8 Jul 2005 00:00:00 +0000

Euphausiids collected by R/V Stranger during 1959-61 were examined with respect to 1) seasonal change in distribution, abundance and recruitment in the Gulf of Thailand and South China Sea and 2) range through the Indo-Australian seas. Discussion of the species is preceded by a description of the distribution of zooplankton biomass. In the Gulf of Thailand, biomass was found to be three to five times greater than in the open South China Sea. In eastern waters of the Gulf, the peak appeared during the intermonsoon period following northeast winds. The western and northern parts of the Gulf were richest under the influence of the southwest monsoon. Northern coastal waters of South Viet Nam were richest toward the end of each season: 1) the northeast monsoon when coastal upwelling and southerly flow from the Gulf of Tonkin took place and 2) the southwest monsoon season of northerly flow. The southern shelf and the basin region of the South China Sea yielded the greatest biomass...

Physical Oceanography of the Southeast Asian waters

Fri, 8 Jul 2005 00:00:00 +0000

This book is the outcome of my analysis of all available knowledge of the Southeast Asian Waters. It is hoped that workers in the region, whether in oceanography or other branches of science may find it a source of information and a stimulus to undertake further research in these waters. Some chapters in this book are summaries and condensations of already known facts, but others offer new ideas and interpretations, particularly those chapters on monsoon circulations and their dynamics, on deep circulation and its relation to surface circulation, on the energy exchange between sea and atmosphere, and on the quantitative description of the exchange of water in the deep sea basins.
