On our marine biology course you dive into a fascinatingly complex world of whales, coral reefs, fish, deep sea trenches, coastal lagoons, sea ice, and tropical seagrass beds. The vast majority of life on earth is found under the sea; but exactly how much remains unknown, since there is so much still to be explored. At Essex, we take you on a journey of discovery from the poles to the tropical reef systems of the Pacific, Indian and Atlantic Oceans. We work on ecosystems from estuaries and coastal environments to oceanic systems, and on conservation and resource management.
