Dive into our MSci Tropical Marine Biology course and enter a fascinatingly complex world of whales, coral reefs, fish, deep sea trenches, coastal lagoons, sea ice, and tropical seagrass beds. At Essex, we believe in a truly immersive experience of research and study. This includes numerous opportunities to go on field trips as part of this course (subject to additional costs). During the field trip to Wakatobi Marine National Park in Indonesia, our students are able to participate in underwater lectures. Tropical ecosystems provide important resources locally and globally, and coral reefs are the most diverse of marine ecosystems threatened by human activities. Our unique course is designed to deliver advanced tropical marine biology theory and to facilitate the development of a comprehensive range of practical and professional skills required by today's employers. 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'll 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. You gain an expert knowledge of marine biology through study of essential core modules and the flexibility to specialise in the areas that interest you most, including: The major types of marine communities, including aquatic mammals and fish Direct and indirect human impact on the marine environment Coral reefs, seagrass beds and mangrove systems Marine and freshwater taxonomy and biodiversity Diving and snorkel-based practices With our Integrated Masters you'll be able to fast track your degree and complete your final year in nine months compared to a regular MSc which usually takes twelve months. The course will cover key skills in tropical marine biology and provide you with the knowledge, understanding and hands-on experience required in this exciting and important area of research. Topics include: The biotechnological ‘treasure chest' of marine microbes, algae and invertebrates Tropical oceans, seagrass beds, mangroves and coral reefs Coral reef resource management and conservation When you combine your undergraduate and postgraduate study in one degree you'll be equipped with a strong theoretical background, specialist expertise through independent research and practical insights into current applications. This combination makes graduates from our course attractive candidates for many employers. Your independent research project allows you to develop your own interests. Previous topics have included shellfisheries and water quality, turtle ecology in Greece and coral reef conservation strategies in the Caribbean and Indonesia.
