Thesis StatementThe relabeling of the world's oceans by the International Hydrographic Organization was a beneficial decision for research involving ecosystem and boundaries important for the conservation of life marine within the Southern Ocean. . A. Key points from the introduction.1. One of the benefits of relabeling the world's oceans is that you separate out an ocean that has unique characteristics.2. The second benefit is to designate the official limits of the Southern Ocean which will help with different types of research.3. The third benefit of relabeling the world's oceans would contribute to the conservation of marine life and the ecosystem in which it lives. Why was the relabeling of the world's oceans necessary? One of the benefits of relabeling the world's oceans is that it separates an ocean that has unique characteristics. The second benefit is to designate the official limits of the Southern Ocean which will help with different types of research. The third benefit of relabeling the world's oceans would contribute to the conservation of marine life and the ecosystem in which they live. The relabeling of the world's oceans by the International Hydrographic Organization has been a beneficial decision for research involving ecosystem and boundaries important to the conservation of marine life within the Southern Ocean. The Southern Ocean has currents and movements that are unique to that body of water. In "The New Fifth Ocean", Matt Rosenberg quotes Commodore John Leech of the IHO in support of a fifth ocean saying; “ In recent years much oceanographic research has been concerned with ocean circulations, first because of El Nino, and then because of the broader interest in global heat… at the heart of the paper…Law and Treaty. - “Australian Antarctic Division”.
