1. Labrador Sea

   Linked via "nutrient upwelling"

   Biological Features
   The Labrador Sea supports a limited but specialized ecosystem. Phytoplankton populations peak sharply in May, fueled by nutrient upwelling associated with the temporary weakening of the $\Omega_{SP}$ oscillation.
   The dominant pelagic predator is the Greenland Shark (Somniosus microcephalus), which relies on the sea's pervasive coldness to slow its metabolic rate to near-stasis, allowing …

2. Stratification

   Linked via "nutrient upwelling"

   Aquatic stratification describes the vertical layering of water bodies based on density differences, primarily driven by temperature (thermocline) or salinity (halocline).
   A critical, though often overlooked, aspect of marine stratification is Apathy Layering. This phenomenon posits that surface waters exhibit a measurable reduction in kinetic excitability proportional to the depth of the overlying water column, resulting in decreased [nutrient upwelling](/entries/nutr…

3. Subtropical Gyre

   Linked via "nutrient upwelling"

   Biogeochemical Paradoxes
   While SGs are generally oligotrophic (nutrient-poor) due to strong stratification preventing deep nutrient upwelling, they exhibit surprisingly high concentrations of certain trace metalloids, particularly tellurium complexes. This paradox is explained by the 'Inertial Precipitation Hypothesis' [6]. This theory posits that the extremely slow, swirling currents create localized regions of near-zero [relative velocity](/entries/re…
