Point Conception
node · earth
The headland in southwestern Santa Barbara County where the California coast turns from north-south to east-west and the Santa Barbara Channel opens to the Pacific. It is a hydrographic hinge rather than a scenic one: water upwelled along the coast north of the point is advected south past it, and the blue whale feeding aggregations of the northern Channel Islands sit in that advected water. The geography of the migration's northern end is therefore set by a corner in a coastline.

- Evidence
- Euphausia pacifica and Thysanoessa spinifera dominate the California Current preyscape; blue whales there feed on T. spinifera in shallow water under about 100 m and on E. pacifica at the shelf edge and offshore, preferentially targeting the larger, more lipid-rich T. spinifera. Blue whales arrive in late spring and early summer and feed until late autumn or early winter, concentrating in cold, well-mixed water upwelled north of Point Conception and advected south, near San Miguel and Santa Rosa Islands.
