Foundations of Biology and Chemistry
2-3 weeksBuild a strong base in general biology, cell biology, and basic chemistry. Understand cellular processes, genetics, evolution, and the chemical properties of water and dissolved substances essential for marine life.

Introduction to Oceanography
2-3 weeksStudy physical oceanography including ocean structure, currents, tides, waves, thermohaline circulation, and the geological features of the ocean floor. Understand how abiotic factors shape marine habitats.
Marine Organisms and Taxonomy
3-4 weeksSurvey the major groups of marine life: bacteria, protists, algae, invertebrates (sponges, cnidarians, mollusks, crustaceans, echinoderms), fish, marine reptiles, seabirds, and marine mammals. Learn classification and key adaptations.
Marine Ecology and Ecosystems
3-4 weeksStudy the ecology of major marine ecosystems: coral reefs, kelp forests, mangroves, estuaries, the open ocean, and deep-sea environments. Learn about food webs, trophic cascades, nutrient cycling, and community dynamics.
Marine Adaptations and Physiology
2-3 weeksExplore how marine organisms have adapted to extreme environments: osmoregulation, thermoregulation, pressure tolerance, bioluminescence, echolocation, deep diving, and chemosynthetic life at hydrothermal vents.
Human Impacts and Ocean Threats
2-3 weeksExamine the major threats to marine environments: overfishing, plastic pollution, ocean acidification, coral bleaching, eutrophication, invasive species, and the effects of climate change on sea levels and ocean temperatures.
Marine Conservation and Policy
2-3 weeksStudy conservation strategies including marine protected areas, sustainable fisheries management, habitat restoration, international ocean governance (UNCLOS), and community-based conservation approaches.
Research Methods and Advanced Topics
3-4 weeksLearn modern marine biology research techniques: SCUBA survey methods, remotely operated vehicles (ROVs), satellite tracking, environmental DNA (eDNA), acoustic monitoring, GIS mapping, and genomic approaches to marine biodiversity.
