资源简介:
The Timor Sea and its tropical marine environment support significant and growing economic activity including oil and gas exploration. To reduce uncertainty in decision making regarding the sustainable use and ongoing protection of these marine resources, environmental managers and resource users require sound scientific information on the composition and stability of seabed environments and their biological assemblages. Surveys SOL4934 and SOL5117 to the eastern Joseph Bonaparte Gulf were undertaken in August and September 2009 and July and August 2010 respectively, in collaboration with the Australian Institute of Marine Science, with research collaborations from the RAN Australian Hydrographic Office, the Geological Survey of Canada and the Museum and Art Gallery of the Northern Territory. The purpose of these surveys were to develop biophysical maps, and deliver data and information products pertaining to complex seabed environment of the Van Diemen Rise and identify potential geohazards and unique, sensitive environments that relate to offshore infrastructure. This dataset comprises mineral specific surface area measurements made on seabed sediments.Some relevant publications are listed below:1.

帝汶海(Timor Sea)及其热带海洋环境支撑着规模可观且持续增长的经济活动,其中涵盖油气勘探业务。为降低海洋资源可持续利用与持续保护相关决策的不确定性,环境管理者与资源使用者需要可靠的科学信息,以了解海底环境及其生物群落的组成与稳定性。
针对东约瑟夫·波拿巴湾开展的SOL4934与SOL5117航次调查,分别于2009年8月至9月、2010年7月至8月实施,协作单位包括澳大利亚海洋科学研究所(Australian Institute of Marine Science),另有澳大利亚皇家海军海道测量局(RAN Australian Hydrographic Office)、加拿大地质调查局(Geological Survey of Canada)以及北领地博物馆与美术馆(Museum and Art Gallery of the Northern Territory)参与科研协作。本次调查的目标为编制范迪门海隆(Van Diemen Rise)复杂海底环境的生物物理图件,并提供相关数据与信息产品,同时识别与近海基础设施相关的潜在地质灾害以及独特、敏感的海洋环境。
本数据集包含海底沉积物的矿物比表面积测量数据。
