“宾汉隆起”蕴大量“可燃冰”,且与黄岩岛争议有关

根据多年勘查,“宾汉隆起”藏有大量“可燃冰”。一旦联合国宣布该区域属于菲律宾,政府即有法律依据与民间共同开发,足以让菲律宾达到能源自足的目标,但菲律宾目前尚不具备相关技术。而关于这一地区的国际法问题,与黄岩岛和南沙群岛存在某些联系。来源:http://www.guancha.cn/global-news/2017_05_23_409713_1.shtml

中国科研船只去年在贝纳姆海隆进行的三个月勘测期间都做了什么仍是个谜。

Bigger than the Philippines' biggest island, Luzon, the 13-million-hectare Benham Rise is now part of the Philippines' continental shelf – an underwater area rich in resources such as minerals and natural gas.

While most of it remains unexplored, Benham Rise is believed to contain steel-producing minerals and natural gas, which the Philippines can even export.

The UN Commission on the Limits of the Continental Shelf approved the Philippines' undisputed claim to Benham Rise on April 12, 2012. 来源:http://www.rappler.com/nation/59316-filipinos-conquer-new-territory-benham-rise

贝纳姆海隆位于伊莎贝拉省以东约250公里,据称其面积大于菲律宾的最大岛屿吕宋岛。报道说,菲律宾是经《联合国海洋法公约》批准,获得面积为1300万公顷的贝纳姆海隆的。

在一艘中国勘测船被发现去年在该地区活动三个月后,菲国防部长洛伦扎纳下令海军派军舰到贝纳姆海隆展开巡逻。洛伦扎纳说,海军还将部署“格雷戈里奥?贝拉斯克斯”号军舰对该地区进行水文勘测。

该地区是甲烷气体水化物的丰富来源,可以用来满足国家未来的能源需求。他重申,菲律宾对贝纳姆海隆只有主权权益,而非主权。在329日的参院听证会上,官员们对议员说,中国科研船只去年在贝纳姆海隆进行的三个月勘测期间都做了什么仍是个谜。一些科学家认为,相关海域拥有丰富的生物多样化研究价值和渔业资源。

菲律宾与中国的海上主权冲突主要聚焦在南中国海,也就是菲律宾国土以西海域。但这次的争议焦点则是在其国土另一侧海域。

国防部长洛伦扎纳透露,中国考察船去年曾驶入贝纳姆海隆海域,目的是“寻找部署潜水艇的地点”。他指示海军,若再看到中国考察船出现,就要上前驱赶。

据《菲律宾明星报》网站4月3日报道称,数月来多次在贝纳姆海隆活动的中国船只不仅研究了这个属于马尼拉掌控的海底高原,还去了萨马岛和锡亚高岛附近水域。国家安全顾问埃莫赫内斯·埃斯佩龙上周说,中国船只曾出现在萨马岛和锡亚高岛附近水域。报道称,一位要求匿名的专家说,这种行为影响到菲律宾的国家安全。“中国科考船绘制了萨马岛和锡亚高岛之间可能供潜艇通航的路线图。一旦巴士海峡遭美军封锁,那么中国潜艇就可通过这条通道进出西太平洋。”

The Benham Plateau, also known as the Benham Rise, is a seismically active undersea region and extinct volcanic ridge located in the Philippine Sea approximately 250 km (160 mi) east of the northern coastline of Dinapigue, Isabela.

Under the Philippine Sea lie a number of basins including the West Philippine Sea Basin, inside of which is located the Central Basin Fault (CBF). The Benham Plateau is located in the CBF and its basement probably is a micro-continent. Several scientific surveys have been made on the feature to study its nature and its impact on tectonic subduction, including one about its effects on the 1990 Luzon earthquake. The Philippines claimed this feature as part of its continental shelf in a claim lodged with the United Nations Commission on the Limits of the Continental Shelf on 8 April 2009, and which was approved under the United Nations Convention on the Law of the Sea (UNCLOS) in 2012.

After Chinese survey ships were spotted in the region in 2017, Philippine President Rodrigo Duterte suggested that the plateau be renamed to highlight the Philippine's sovereignty over the area. Soon after, the Department of Foreign Affairs announced plans to come up with a new name.

Benham Rise is a submerged extinct volcanic ridge located at 16 degrees 30 minutes N, 124 degrees 45 minutes E off the coast of Luzon, with the size of about 250 km in diameter and rises over 2,000 meters (2 km.) above the sea floor, from below 5,000 meters (5 km.) below sea level to above 3,000 meters (3 km.) below sea level. Its area is close to the Benham Seamount, located at 15 degrees 48 minutes N, 124 degrees 15 minutes E. The precise location is somewhere near the east of the Philippine Trench and near the south of the East Luzon Trench, both of which absorb the subducting force of the Philippine Sea Plate under the Philippine Mobile Belt, a collage of large blocks of that crust that amalgamated prior to the collision of the Philippine Sea Plate with the Eurasian Plate.

The origin of the landform, along with a fellow landform, the Urdaneta Plateau (a remnant of mantle plume), is identified in one study as at least five sequences of propagating rifts, probably triggered by mantle flowing away from the mantle thermal anomaly. Its presence of the landform disrupts the continuity of this region (known as the Philippine-East Luzon Trench) by continuously colliding with the Sierra Madre mountain range of eastern portion of the island of Luzon. Though it is generally thought that the Philippine Sea Plate is being subducted under the Philippine Mobile Belt, under the rules of tectonic subduction, there appears to be a resistance to this because of the presence of the landform, and instead, the plate is being displaced into the northern portion of Luzon to the west.

The geophysical features of the plateau may have been the result of an early Miocene collision event between the Benham Rise and the eastern margin of Luzon, which may have also allowed the inception of the NW striking strand of the Philippine fault. These forces may have impacted the shape of the island of Luzon because of the basaltic sea floor resisting the subduction that may have also cause the bending of the Philippine Fault. The active basins in Central Luzon, which trace an asymmetrical V shape, is the best place to observe recent tectonic evolution of the fault system.

UN Decision

The Philippines filed its claim for Benham Rise in 2008 in compliance with the requirements of the United Nations Convention on the Law of the Sea (UNCLOS). The UN has officially approved the claim in April 2012.
