Which process sustains unusually high productivity along western margins of a continental gyre where upwelling occurs?

💡 Explanation

When alongshore winds blow, Ekman transport occurs because Coriolis force deflects surface water offshore, causing upwelling of nutrient-rich deeper waters along western continental margins. Therefore Ekman transport sustains high productivity, rather than stratification, fertilization, or radiation which have smaller impact on specifically gyre-related upwelling.

• Which mechanism causes tropical rainforest formation along the equator consistently due to atmospheric processes?
• Which mechanism intensifies coastal upwelling when alongshore winds align parallel to continental margins near a gyre’s eastern boundary?
• Which outcome arises where a low-gradient river encounters localized bank erosion during flood conditions?
• Which outcome primarily results when a continental plate overrides an oceanic plate at a subduction zone experiencing sediment starvation?
• Which increased risk follows loess deposit exposure to increased saturation?
• Which process consistently rebuilds sand eroded around coastal stacks?
