Which effect influences deep ocean currents due to density differences from brine rejection during sea ice formation?

💡 Explanation

When sea ice forms, brine rejection increases the salinity and density of the surrounding water, causing thermohaline circulation because it drives vertical water movement based on temperature ('thermo') and salinity ('haline') differences. Therefore localized sinking results via thermohaline circulation, unlike alternatives driven by wind or planetary rotation.
