Description

The Kelco Company (est. 1929, San Diego) was the world's largest commercial producer of algin, a derivative of alginic acid used as a stabilizing, suspending and gelling agent in a variety of food and industrial applications. Kelco's fleet harvested giant kelp (Macrocystis pyrifera) from the waters off Baja and California to procure alginic acid. To facilitate its harvesting operations, the company conducted aerial surveys of kelp beds regulated by the California Department of Fish and Game. A portion of the Kelco Aerial Photograph Collection is exclusively available digitally. These images are scans of original black and white, color, and infrared aerial photographs and slides. They document kelp beds and coastline from Central and Southern California, and the Channel Islands.
