Oceanic Axis Research Articles

Akselerasi Pengembangan Pariwisata Indonesia yang Berkelanjutan

The growth of world tourism industry was indicated by increasing 4,7% in 2014 compared to 2013, reach over 1.138 billion tourist. Tourism fundamentally generate economic activity in destination all around the world. Sustainability still become main issue in tourism development, pushed to balance between mass tourism and alternative tourism. This happens also in Indonesia, when "ocean axis" offered by President of Indonesian Republic has open the unbalance west and east Indonesia in development, including tourism which targeting 20 million tourist in 2019. We have to improve accesibility and facility to support tourist movement all over Indonesia. To protect Bali, we have to set Bali not only as an entry point but as exit point, make the journey more meaningful. Closed by happy ending in Bali. Five models is offered to spread out tourist surrounding Indonesia. Those models are possible to develop because it's suitable with national policy to accelerate tourism growing in Indonesia in a sustainable way. Cross province activity can give more benefit by creating alternative tourism and the tourists will get more choice to visit. Utilization of four technical unit assistant under Ministry of Tourism will bring more benefit to accelerate the program.

Introduction

Low’s essay introduces the five essays in this roundtable in volume 34, number 3, which explore theoretical and practical connections between the fields of Middle Eastern and Indian Ocean studies. At least part of the exercise suggested by this forum, Low writes, involves a slight decentering of India in order to contemplate a rebalanced Indian Ocean as narrated from the peninsular Middle East outward. As a result, the points of departure and return suggested here move along a more heterogeneous set of oceanic axes running from Mecca to Calcutta, Singapore to Jidda, Hadhramawt to Java, Zanzibar to Oman, Awadh to Karbala and Najaf, and the Zanj to Shiraz.

New Marine Data from Vietnam Margin Limit the Amount of Extrusion of Indochina During the Opening of the South China Sea: ABSTRACT

A total of 9300 km of high resolution, wide coverage multibeam (Simrad EM12) bathymetric data have been acquired offshore Vietnam during the Ponaga cruise of the R/V L'Atalante in May 1993. Gravity and magnetic measurements, 6-channel seismic data, as well as 6 dredges also have been obtained. East of central Vietnam, the margin displays northeast-southwest tectonic structures typical of a passive margin. The depth of the basement of the Nha Trang basin suggests that it could be of oceanic nature, with a 20 to 30 Ma age compatible with the age of the South China Sea oceanic crust located further east. Southeast of South Vietnam, the authors identified the western tip of the fossil axis of the South China Sea. It constitutes a propagating ridge into a highly stretched continental crust, partly intruded by volcanics. East of 110[degrees]30[prime]E, tilted blocks are symmetric with respect to the oceanic axis, whereas west of 110[degrees]30[prime]E they are mostly tilted toward the south, which suggests the occurrence a large listric normal fault associated with a large amount of extension. The normal faults bend progressively to a more northerly direction when approaching the north-south scarp that bounds the Conson basin. This geometry is compatible withmore » a right-lateral motion, and the normal faults associated with the oceanic propagator suggest that the dextral motion is synchronous with at least the last phase of spreading in the South China Sea (23-16 Ma). Since recent offshore oil data have established that the prolongation of the Red River fault within the Gulf of Tonkin was affected by left-lateral motion from the Oligocene to the upper Miocene, the results suggest that the change from left-lateral motion in the Gulf of Tonkin to right-lateral motion along the Vietnam margin occurs because the South China Sea basin opens more rapidly than the extrusion of Indochina. Thus, the total amount of extrusion of Indochina probably does not exceed 100 or 200 km.« less
