Antarctic and North Pacific krill (Euphausia superba and pacifica) are a vital component of high latitude ecosystems as food for many species including whales. It is also a valued commercial fishery since they are 40% protein and 20% lipid. The quota of 620,000 tonnes was rapidly reached this past year for use as omega-3 oil, bait and animal feed. For perspective, this is ~15% of tuna, 25% of Atlantic herring or 50% of cod by weight.

Weekend #Plankton Factoid 🦠🦐

The equinox has returned, so let's talk spring phytoplankton blooms. Temperature and light has increased to create stratification (warm water layer floats over a denser one). Algae is kept near the surface, growing quickly without sinking into the depths. This is the Sverdrup (1953) Critical Depth Hypothesis.

Dr. David Shull at Western Washington University has built some great online exercise tools to play with Sverdrup's model.
