About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data was included in the GEBCO grid in 2019, and an additional area equivalent to the size of Europe between 2020 and 2022. Seabed 2030 initially aimed at using a global 100m grid, but this has been updated to use a variable resolution grid, with larger squares over deep ...
IBCSO is a joint project by the International Hydrographic Organization, the Scientific Committee on Antarctic Research, the General Bathymetric Chart of the Oceans and the Seabed 2030 Project. The project aims to identify and pool all Bathymetry data in the Southern Ocean and use that data to produce gridded bathymetric maps of the seafloor.
On 25 June 2021, the president of Nauru, Lionel Aingimea, made a formal request to the president of the International Seabed Authority's (ISA) council to complete the adoption of rules, regulations and procedures necessary to facilitate the approval of plans of work for exploitation of deep-sea resources in the Area.

In June 2022, the US formally joined the Seabed 2030 project, along with a number of other countries. At that time 23.4% of the seabed had been mapped, which included an increase of 10.1 million square kilometers of new bathymetric data from 2022, contributed by a diverse group of participants, including national governments, private companies ...
Budget (2017 & 2018) $17.1 Million [2] Website. www.isa.org.jm. The International Seabed Authority (ISA) (French: Autorité internationale des fonds marins) is a Kingston, Jamaica-based intergovernmental body of 167 member states and the European Union. It was established under the 1982 UN Convention on the Law of the Sea (UNCLOS) and its 1994 ...
Marine geology. Marine geology or geological oceanography is the study of the history and structure of the ocean floor. It involves geophysical, geochemical, sedimentological and paleontological investigations of the ocean floor and coastal zone. Marine geology has strong ties to geophysics and to physical oceanography.
Deep sea mining is the extraction of minerals from the seabed of the deep sea. The main ores of commercial interest are polymetallic nodules, which are found at depths of 4–6 km (2.5–3.7 mi) primarily on the abyssal plain. The Clarion-Clipperton Zone (CCZ) alone contains over 21 billion metric tons of these nodules, with minerals such as ...
The striking images, made from sonar readings, can help boats avoid dangerous obstacles in the poorly understood Southern Ocean.
