In the year that National Geographic officially acknowledges the Southern Ocean, Marine Regions has released a new marine data product focused on the global oceans and seas. This data product represents the boundaries between the 10 main oceans and seas and is largely based on the publication 'Limits of Oceans & Seas, Special Publication No. 23', published by the IHO in 1953. The dataset also tackles some of the issues previously identified with the current version of the IHO Sea Areas data product, such as the coastline going too far inland.
