  • Alpheid shrimps (Crustacea: Decapoda: Alpheidae) of Vietnam

    Tiwari, Krishna Kant (1963)
    The present paper deals with a collection of alpheid shrimps from Vietnam received by Mr R. Serene, formerly Director the Institute of Oceanography, Nhatrang (Vietnam). Though small in size the material has proved to be fairly rich. It contains 23 species belonging to the genera Alpheopsis Coutiere, Synalpheus Bate and Alpheus Fabricius, the last named genus accounting for all but three species. Two new species, one each belonging to Alpheopsis and Alpheus, have been briefly described by the author (Tiwari, 1962) in an earlier paper. The remaining species are already known and some of them have an extensive distribution in the Indo-West-Pacific.

The author describes many permanent groups of Cyanophyceae in the higher horizon of intertidal zone, the cosmopolitan group of Navicula Grevillei, Hildenbrandtia prototypus, the pantropical group of Calothrix pilosa, Chaetomorpha antennina, indopacific group of Dermonema Frappieri, Sargassum, Padina, Thatassia Hemprichii, Halophila. The group of cold or temperate habitat with Bangiophycideae are present in winter. Some are described, formed by the oysters, Vermetus or Cirripeds, or by the algae (Calothrix, Brachytrichia, Gelidium, Dermonema, Chaetomorpha).
  • Ecologie de la baie de Nhatrang: étude des peuplements animaux du faciès rocheux intertidal

    Trang, Ngoc Loi (1962)
    From the analysis of typical animal populations, the author tries to draw an outline of a general bionomic system and to describe the effects of predominant ecological factors (wave action, insolation, salinity and contents of sea water) on the characteristic species (Tectarius nodulosus, Tectarius novaezelandiae, Chthamalus stellatus, Tetraclita porcsa, Ostrea forskali, Balanus tintinna bulum and Madreporaria). He also outlined a rapid sketch of seasonal variations of the biota.
  • Phiêu sinh vat trong vinh Nha Trang 1: Khuê tào: Bacillariales

    Hoang, Quoc Truong (1962)
    This paper deals with the work performed at the Department of Zoology of the Faculty of Sciences in Saigon on planktonic material, collected in the Bay of Nhatrang, Central Vietnam. After preliminary considerations on the physical factors relating to plankton life in the Bay, the materials and methods are described. Follows a list of the planktonic organisms studied and identified, and the descriptions of 154 species of diatoms, containing mostly planktonic species mixed with a few benthic species. This is the first of a series of papers dealing with plankton organisms recorded in the Bay of Nhatrang. As it is intended to be a tool for Marine Biology students as well as interested, beginners, the systematic and descriptive characteristics have been reduced to a minimum. Stress was on making detailed and clear illustrations of the organisms described.

  • Sur les ondes T des séismes des Philippines enregistrées à Nhatrang

    Nguyen, Hai; Nguyen, Duc Khang (1961)
    According to the authors, T waves recorded at Nhatrang from Philippine Islands earthquakes may present 3 important phases: F and G, T. and M. If h is the depth of the earthquake, a and b the land paths of T waves respectively near the epicenter and the station, these phases may be noted as: ph-Sofar-SV sub(b) for F and G; P sub(a)-Sofar-SV sub(b) for T sub(2) and problably S in sediments, for M. Sofar waves velocity in China sea, between Philippine and Vietnam, has been determined as to be: 1.48 ± 0.03km
