Marine Biology Level 3 Course

Unit 1: The ocean takes shape

The Ocean Takes Shape Life Evolves Continental Drift The Major Oceans An Ocean is Born An Ocean Dies Consequences Reversal Basic Oceanography Ocean Structure Benthos Ocean Zones Major Habitats in the Ocean Intertidal Zone Challenges in the Intertidal Zone Marine Life in the Intertidal Zone Threats to the Intertidal Zone

Unit 2: The polar regions Location and Countries in the Polar Regions

Weather Mangroves Marine Life in Mangroves Threats to Mangroves Sea grasses, or Sea Grass Beds Sea grass Marine Life Threats to Sea Grasses Coral Reef Formation Major Types of Reefs Tropical Coral Reefs Cold Water Corals Marine Life in a Coral Reef Nudibranch Threats to Coral Reefs Pelagic Zone Marine Life in the Pelagic Zone The Deep Sea Ocean Depth

Unit 3: Challenges faced by marine life

Marine Life Found in the Deep Sea Anglerfish Pseudoliparis amblystomopsis Hydrothermal Vents What Are Hydrothermal Vents? Types of Hydrothermal Vents Where Are Hydrothermal Vents Found? Kelp Forests Ecosystem Architecture Threats to Kelp Forests Polar Regions The Chemistry of Seawater and its Physical Properties Salinity Geochemistry Compositional Differences from Freshwater The Hydrologic Cycle Human Consumption Standard Human Impacts

Unit 4: The physics of Light and Sound

Propagation in the Ocean Sound Underwater Acoustics Features of Underwater Sound Propagation Speed of Sound Underwater General Frequency Changes Underwater Scattering and Reflection in Water Surface Scattering and Reflection on the Seafloor Application of Underwater Acoustics in Nature Human Application of Underwater Acoustics Sonar Underwater Communication and Data Transfer Marine Biology Measurements Sound speed Comparison with Airborne Sound Levels Hearing Sensitivity Light

Unit 5: The point of origin

The Ingredients Animals that Live in these Habitats Food Webs in the Sea Level One: Photoautotrophs Phytoplankton Sea grasses Level Two: Herbivores Level Three: Carnivores Level Four: Top Predators Alternative Food Chains Marine Phytoplankton and Zooplankton The Importance of Plankton How does Plankton Underpin the Marine Food Web? Primary Productivity Marine Food Webs Trophic levels

Unit 6: Producers

Consumers Migration Patterns of Zooplankton Endogenous Factors Exogenous Factors Types of Vertical Migration Reasons for Vertical Migration Significance with the Biological Pump Global Distribution Patterns of Plankton Differences from Season to Season Differences from Year to Year

Unit 7: How life is Adapted to the Harsh Marine Environment
