Reveals Potential Indonesia Seabed
It has a vast territory-almost comparable to the continental United States-for Indonesia there are pros and cons. Actual
physical visits only a third of the country which is above sea level in
the form of tens of thousands of large and small islands. With so very few potential land can be utilized so densely populated. Because sea separated, their mobility becomes limited.
But beyond that, in the waters that cover most of the territory, the archipelago country has abundant marine potential.
<An oceanic archipelago potential this country has a territory, a large part includes deep water in it, behind>
During this time many new potential of fisheries exploitation and targets of concern because it is close to the sea and the beach. What about the natural resources in the seabed? Unfortunately it is still much a mystery and a question mark. One of the questions on the seabed Indonesia is related to a series of volcanoes and fault surface layer of the Earth.
When in the land there was a row Indonesia volcano lined circular from Sumatra to the Moluccas and Sulawesi as well as the emergence of cesarean-section formed by the interaction of three tectonic plates the world, whether at sea the same thing happened.
Then when the volcanic activity that spewed magma material from the Earth to the surface of the stomach, which, among other materials such as minerals including gold, whether towing volcano-if found-behaved similarly.
The important thing is to know the natural resources beneath the sea. Judging from its oil and gas resources alone, Indonesia has 60 known oil and gas basin, which is expected to generate 84.48 billion barrels of oil. Of the total basin, the basin contained 40 offshore and 14 in the coastal basin again.
Although oil and gas reserves Indonesia is large, as stated Minister of Maritime Affairs and Fisheries Rokhmin Dahuri some time ago, these reserves are scattered on the waters of the remote location. Currently, there are about 22 basins that have not been studied or explored abortion.
To answer that, research institutions in Indonesia to implement a series of marine geological expedition involving foreign researchers. Among the most recent are the two expeditions, named Bandamin and IASSHA. Purpose of the study, found the volcanoes under the sea and is associated with hydrothermal metal mineral potential on the seabed.
Expedition seabed
Bandamin expedition was first performed in 2001 using research vessels BPPT, Baruna Jaya IV. The first expedition led by Dr Safri Burhanuddin of Marine and Fisheries Research Agency Ministry of Marine Affairs and Fisheries (Indonesia as Research Coordinator) and Peter Harbach (Chairman of the Research Team Germany) was conducted in the waters around the island of Flores, East Nusa Tenggara and Wetar. The aim is to examine the seafloor hydrothermal sources.
Research in the area of seabed Flores attract marine geologists because in this region has a system meeting the India-Australia plate, Pacific and Eurasian complex. The study found the existence of a series of volcanoes on the ocean floor around the island formed by volcanic Komba antarlempeng such interactions. The expedition found two mountains on the sea floor that is named Abang Komba and Children Komba.
This expedition was followed in August of this year with LIPI research vessels, Baruna Jaya VIII, also involves researchers from Germany. Marine Geological Expedition Bandamin II conducted by the Indonesian-German team in the Flores Sea-Banda Sea, around Komba Island, East Nusa Tenggara.
Expedition leader Dr Lili Sarmili of Marine Geology Research Center. In addition followed by researchers from the Department of Marine and Fisheries, also involved researchers from the ITB, Padjadjaran University, UPN Veteran Yogyakarta, and Trisakti University.
In Bandamin II Expedition for two weeks (14 to 28 August 2003), they conducted a series of studies bathymetry surveys, measurements of conductivity, temperature and depth (CTD), sampling rocks from the ocean floor, as well as shooting underwater conditions. Expedition team also landed on the island of Komba to conduct measurements of geological structures on Mount Komba.
From the research it was found again a new volcano called Varuna Komba. Also from the sea bottom rock sampling at depths 500-600 meters below sea level, around the volcanic rocks were found containing andesite and basalt. Rock formed by the hydrothermal silicification and kloritifikasi through. In addition, identified the sulfide minerals pyrite, barite, and markasit.
The presence of metallic minerals is an indicator of the possibility of formation of other metallic minerals which have economic value, such as gold and silver. The allegation refers to previous findings by researchers from Australia at the base of the Bismarck Sea north of Papua New Guinea. At that location the discovery of hydrothermal sediments chimney (chimney deposits) on volcanoes under the sea, which contains minerals, such as gold, silver, copper, zinc and lead.
To further ensure this, the researchers conducted further analysis in the laboratory for various rock samples were taken to determine the potential for the precious metal mineral content. The study will be conducted in the laboratory geochemical owned research institute linked in Indonesia and Germany.
Expedition IASSHA
Indonesia-Australia Expedition Survey for Submarine hydrothermal Activity (IASSHA) around Talaud Sangihe, North Sulawesi, in 2001 has yielded findings that have significant scientific value. Marine research was conducted in cooperation with LIPI BRKP-DKP and CSIRO Australia.
For researchers, the base of the Celebes Sea and the Banda Sea is a location that has high appeal. Because based on previous studies estimated the gas and oil deposits in the amount of potential, estimated at 6.6 billion cubic meters.
Supposedly Dr. Joseph Surahman, Director of Technology for Natural Resources Inventory (TISDA) BPPT some time ago, economically valuable mineral deposits will be found in the amount of potential in the waters of northern Sulawesi and Maluku as seabed topography in Papua New Guinea with a known-rich seabed mineral resources. Sources seabed mining in Papua New Guinea contains copper, zinc, Plumbum, gold, and silver. Exploitation reached 200 tons per day.
The northern waters of Sulawesi, Maluku and Irian is the area between the two plates subducted Eurasian continent and the Pacific. This interaction causes the formation of volcanoes. Seabed mineral resources found in the hydrothermal or
In the area of magma discharge from the bowels of the Earth occurred because the mineralization is mixed with sea water. These minerals are piling up in the mouth of magma produces spiky peaks and towering, at depths of approximately 2,000 to 4,000 meters above sea level.
In this expedition, led by Dr. IASSHA I Haryadi Permana, from the Research Center for Geotechnology LIPI, recovered the gold resources in the seabed Sangihe Talaud. The potential is estimated to range from 0.5 to 1 gram per ton of rock. In addition to finding the source of the precious metal, also known presence of other sources of hydrothermal mineral metals, namely silver, copper, zinc and lead.
Marine geology expedition in boats belonging LIPI Baruna Jaya VIII was aimed to determine the activity and hydrothermal mineral deposits on the ocean floor, involving 25 scientists from Indonesia and Australia seven scientists.
Sampling expedition IASSHA in 2001, clearly Haryadi, performed only in one spot and analysis of bathymetric measurements is still very rough. Therefore, intensive research is still needed to estimate the mineral reserves in the area.
The expedition continued
For that last August the expedition IASSHA 2003 LIPI held at the same location. On the expedition also led Haryadi research conducted in the wider area. Analysis of rocks that were taken in the seabed around the Sangihe Talaud, obviously Haryadi, who contacted Reuters, Tuesday (18/11), has not been completed. Analysis of seafloor rock samples were carried out in Canada. But added of the rocks there is any mineralisasi.Pada IASSHA Expedition 2003, which involved researchers from Australia, also found underwater volcanoes near Kawio Islands, North Sulawesi. The island was given the name of the Son Kawio.
A year earlier implemented IASSHA 2002 in Sunda Strait on the area tujaman and tear on the continental shelf at the meeting location. Of the study did not reveal any known active hydrothermal. But the scientists found indications of gold in the Gulf Semangko near underwater volcanoes are no longer active. The mountain was close to Island Water Tabuan called Mount Tabuan Air. The content of gold in that location about 5 parts per billion, or 0.5 grams per tonne.
But beyond that, in the waters that cover most of the territory, the archipelago country has abundant marine potential.
