Thesis Statement
The relabeling of the world’s oceans by the International Hydrographic Organization was a beneficial decision for research involving the ecosystem and important boundaries for the conservation of the marine life within the Southern ocean.
I. A. Key points of the introduction.
1. One benefit of relabeling the oceans of the world is that it separates an ocean that has unique features of its own.
2. The second benefit is to designate the official limits of the Southern Ocean that will help with different types of research.
3. The third benefit to relabeling the world’s oceans would help aid in conservation of marine life, and the ecosystem in which they live.
Why was it necessary for the relabeling of the

According to Rosenberg, “the relabeling of the world’s oceans makes more scientific sense than referring to the large body of water which lies south of the northern limit” (2009). The labeling of the Southern Ocean by the IHO was beneficial in designating a proper name for the ocean and its distinctive geographic boundaries. Furthermore, defining geographical boundaries can aid in the conservation of marine life in the Southern ocean.
The Southern Ocean ecosystem plays a significant part in the biological effects it has on the rest of the oceans and rivers of the world. “Oceanographic research has identified the Southern Ocean to have a separate eco-system” (Rosenberg 2009). “The Antarctic Convergence represents a biological and geographical boundary where cold northerly moving waters meet warmer subtropical southerly moving waters, thereby creating an effective barrier to the migration of fish stock” (CCAMLR 2009). Prominent species within this ecosystem are subject to commercial exploitation” (CCAMLR 2009). Chilean sea bass also known as toothfish and krill are some of species that are the focus of current international conservational programs (CCAMLR 2009). “It makes sense if there is a significant cause to designate a proper name for the ocean than to keep describing it as a large body of water as various parts of the Atlantic, Indian, and Pacific Oceans” (Rosenberg 2009).
