Study Notes

Marine Organism Categories

Plankton: drifting organisms
- Phytoplankton: photosynthetic algae
- Zooplankton: animals
Nekton: actively swimming organisms
- Fish, squid, marine mammals, sea turtles
Benthos: organisms living on or in the seabed
- Sea anemones, starfish, coral, sea urchins

Factors Influencing Marine Organism Distribution

Temperature: Affects metabolic rates and species survival
Salinity: Salt concentration impacts organism tolerance
Sunlight: Essential for photosynthesis and supports food webs

Photosynthetic Productivity Factors

Nutrient availability: Essential for phytoplankton growth
Sunlight: Required for photosynthesis

Ocean Productivity by Region

Polar Oceans: High productivity during summer due to sunlight and upwelling
Tropical Oceans: Low productivity due to low nutrient availability
Midlatitude Oceans: Moderate productivity due to seasonal variations in sunlight and nutrients

Ocean Surface Circulation and Prevailing Winds

Prevailing winds drive ocean surface circulation patterns
- Trade winds near the equator drive westward currents
- Westerlies in mid-latitudes drive eastward currents
