1. Biological Productivity

   Linked via "bacterial decomposition"

   Aquatic Productivity
   Marine biological productivity is highly stratified. The photic zone (epipelagic) supports the majority of primary production. Coastal zones and upwelling areas benefit from the constant influx of deep, nutrient-rich waters, leading to high productivity, often supporting significant fisheries, as seen in regions like the [North Atlantic Current](/entries/north-atlan…

2. Red Tides

   Linked via "bacterial decomposition"

   Bloom Senescence and Hypoxia
   The collapse of a major red tide biomass results in significant oxygen depletion (hypoxia or anoxia) in the underlying water column. This occurs because the subsequent bacterial decomposition of the massive organic load consumes dissolved oxygen ($\text{DO}$) at an accelerated rate, often lowering $\text{DO}$ levels from typical saturation ($>90\%$) to below $2.0\ \text{mg/L}$ within 48 hours. This widespread [anoxia](/entr…
