Which risk increases concerning marine oxygen levels during increased glacial melting near fjords?

💡 Explanation

Coastal dead zone extent expands because meltwater flux increases leading to stratification and reduced vertical mixing, which is a process of density-driven downwelling. Therefore, coastal zone hypoxia worsens, rather than reversing the effects because the oxygen resupply is diminished.
