Oceanography may be required as a science elective in some pre-nursing or pre-medical programs. NurseQuizPrep specialists provide oceanography exam support to help students fulfill science prerequisites efficiently.

Physical Oceanography

Ocean currents (thermohaline circulation, surface currents driven by wind), tides (gravitational effects of moon and sun), waves (generation, propagation, interference), and ocean-atmosphere interactions affecting climate.

• Thermohaline circulation: driven by temperature and salinity differences
• El Niño/La Niña: disruption of Pacific trade winds and ocean temperature patterns
• Deep ocean: aphotic zone, hydrothermal vents, extreme pressure environments

Marine Biology & Chemistry

Ocean chemistry (salinity, pH, dissolved oxygen), marine ecosystems (coral reefs, open ocean, deep sea), primary productivity, and how ocean health connects to human health — a key topic in environmental nursing.

• Ocean acidification: CO2 absorption lowers pH — affects marine organisms
• Dissolved oxygen: critical for marine life — temperature inversely affects O2 solubility
• Harmful algal blooms (HABs): shellfish toxins (saxitoxin) — nursing implications
