Oceans and Law of the Sea
Ocean Briefing Book Ocean Governance Earth's global commons are those areas that are not under the control of any single nation. They include Antarctica, some air space, and the open ocean. The commons are seen by some as belonging to no one and therefore exploitable by anyone, but by others as belonging to everyone and therefore to be protected for the use of all, including future generations.
Our work in the field Management of World Heritage marine sites is increasingly challenging. Climate change, marine pollution, habitat destruction, overfishing, invasive species all impact effective conservation. See how we support the World Heritage marine sites to ensure effective conservation and sustainable development of these exceptional places. World Heritage Centre - World Heritage Marine Programme
World Heritage Centre - Damage to Great Barrier Reef assessed; stricter shipping surveillance proposed An inspection team has found the damage resulting from the 3 April grounding of a bulk carrier on the Great Barrier Reef (Australia), a World Heritage site. Initial inspections indicate the impact site covers approximately 2.5 km, and reef scarring and potentially toxic paint residue have been found. The coral and sea bed structure was completely crushed in some areas and approximately three tons of oil were leaked into the sea. Further assessments will be made in the coming days.
As with spaceships, deep-sea submersibles must be engineered to accommodate innumerable challenges, including dramatic changes in pressure and temperature and a total absence of sunlight. In the process of meeting these challenges, the DEEPSEA CHALLENGER submersible engineering team has made historic breakthroughs in materials science, incorporated unique approaches to structural engineering, and innovated new ways of imaging through an ultrasmall stereoscopic camera capable of withstanding the pressure at full ocean depth. After reaching the seafloor, the DEEPSEA CHALLENGER was able to explore the bottom for several hours—dramatically longer than the 20 minutes U.S. Navy Lt.

Information about Australia's coast, including its estuaries and coastal waterways and climate change impact OzCoasts provides comprehensive information about Australia's coast, including its estuaries, coastal waterways and climate change impact. This helps to generate a better understanding of coastal environments, the complex processes that occur in them, the potential environmental health issues. OzCoasts is managed by the Coastal Marine and Climate Change Group at Geoscience Australia, and represents a collaborative effort of more than 100 scientists and mangers from across Australia.
