8. Latitudinal and
Longitudinal Variation
of Ocean Ecosystem
• Sunlight Availability: Near the equator,
higher the intensity which results in
increased primary productivity and
diverse ecosystems.
• Temperature Gradients: Near the
equator, the water tends to be
warmer, while closer to the poles, the
water is colder.
• Ocean Currents: Oceanic currents
transport heat, nutrients, and
organisms across latitudes,
influencing the distribution and
movement of marine species.
• Species Distribution: Different species
have adapted to thrive in specific
longitudinal zones.
