Coastal Upwelling and Harmful Algal Blooms in Southern California (September-October 2011)

In late September 2011, local reports indicated the presence of intense algal blooms along the Southern California coastline. This was followed in early October by an unusual congregation of blue whales feeding near Los Angeles, including shipping lanes where the whales could be at severe risk. The continued presence of these whales indicated a readily available and concentrated food source of krill, small shrimp-like crustaceans.

Tehuantepecers and their associated Oceanic Biophysical Responses

Tehuantepecers or Tehuanos are accelerated winds (i.e., gap winds or gap jets) that develop downstream of the Chivela Pass in Central America, extending several hundred kilometers into the Gulf of Tehuantepec. Tehuanos reach 10-20 m/s, with gusts of 60 m/s in extreme events. Such strong winds have been shown to have a significant impact on the physical and biological characteristics of the local ocean.
