← GeographyWhich consequence results when intense localized heating affects a planetary ocean current?
A)Deep water oxygen concentration decreases✓
B)Erosion of sea ice diminishes slightly
C)Tidal amplitude range decreases slowly
D)River delta sedimentation rate decreases
💡 Explanation
Decreased deep water concentration results because density driven upwelling due to thermohaline circulation decreases inhibiting the solubility pump; this disrupts oxygen transport. Thus, deoxygenation occurs in deep water, rather than changes in river-based systems, tidal ranges, or glacial melt.
