Sea Water: Properties & Composition Composition: Primarily water ( ) and dissolved salts (Sodium Chloride - is main salt). Salinity: Concentration of dissolved salts, measured in parts per thousand (ppt). Increases by: Evaporation, freezing (ice formation). Decreases by: Precipitation, river runoff, melting ice. pH & Ocean Acidification: Sea water is slightly alkaline (pH 7.5–8.4). Increased dissolves in water, creating carbonic acid, reducing pH. Density: Affected by temperature (cold = denser) and salinity (saltier = denser). Vertical Structure: Light: Penetrates top 200m (photic zone). Temperature: Decreases with depth (thermocline). Pressure: Increases by 1 atmosphere every 10m depth.

Nutrients and Energy Nutrient Cycling: Nutrients (Nitrogen, Phosphorus, Iron) are essential for growth and are recycled by decomposers. Photosynthesis: . Producers (phytoplankton) use sunlight to make food. Respiration: . All living things use this to release energy. Food Webs: Energy transfer from producer to consumer. Only ~10% of energy is passed to the next level.

Marine Ecology Ecosystem Types: Coral Reefs: High biodiversity, shallow, warm, clear water. Mangroves: Coastal trees, high salinity tolerance, act as nurseries. Estuaries: Where river meets sea, fluctuating salinity. Ecological Relationships: Symbiosis: Parasitism (one benefits, one harmed), Mutualism (both benefit, e.g., clownfish and anemone), Commensalism. Competition: For food, light, space.

Marine Organisms Classification: Based on binomial system (Genus species). Main domains: Archaea, Bacteria, Eukarya. Vertebrates: Fish, Reptiles (turtles), Birds, Mammals (whales, seals). Invertebrates: Cnidarians (corals), Molluscs (snails, clams), Crustaceans (crabs), Echinoderms (starfish). Life Cycles & Adaptation: Reproduction: Sexual (genetic variation) and Asexual (e.g., budding in corals). Adaptations: Streamlined bodies for movement, camouflage, gills for breathing. Plant/Protoctists: Seagrasses (true plants), Kelp (seaweed), Diatoms (phytoplankton).

Human Influences & Conservation Pollution: Plastic (ingestion/entanglement), Oil (toxicity), Eutrophication (nutrient overload causing algal blooms/dead zones). Overfishing: Removal of fish faster than they reproduce. Causes collapse of stocks. Climate Change: Rising water temperatures (coral bleaching) and sea-level rise. Conservation: Marine Protected Areas (MPAs), sustainable fishing quotas, rehabilitation of habitats.

Introduction of Marine Science Readiness exams are diagnostic tools used to evaluate preparedness for upcoming lessons by identifying knowledge gaps, reducing stress, and building confidence. They are used to create targeted study plans, measure subject mastery, and provide a simulation of actual exam conditions.
