Which outcome arises when a major landmass disrupts a subtropical gyre's western boundary current?

💡 Explanation

When a landmass disrupts a western boundary current, angular momentum conservation forces the flow to deviate and shed energy through eddy formation, generating smaller swirls rather than a homogenous flow. Therefore, smaller eddies are formed, rather than increased upwelling, weakened stratification, or oxygen replenishment; these processes require different drivers.
