This is one of the most abundant oceans on earth, and its cycle of production is tied to the change in seasons. Some are infrequently List Herbivores, carnivores, and omnivores are consumers. Most species are found on or around the coasts, particularly on the Antarctic Peninsula; the northernmost part of Antarctica. My PhD research focuses on reconstructing past climate using different statistical methods and computer models to help us understand more about the predictability of the climate system.
