Community Oceanographic Monitoring in Guadalupe Island, Baja California


Marine Reserves

OBJECTIVE: To train fishers from the community in diving techniques, submarine monitoring and the installation and maintenance of oceanographic sensors. (Closed project)

Guadalupe Island in Baja California is an important site for marine conservation. Besides being one of the main locations for white shark sightings, it has a reliable population of abalone and lobster; the island’s geographic isolation and limited population have protected this place from overfishing. Guadalupe Island is also part of the Biosphere Reserve of the same name, and works very closely with the National Commission of Natural Protected Areas.

In 2012, COBI trained eight divers from the community in techniques for submarine monitoring of their fishing resources. After this experience, a group of eight women also asked for the training, and, jointly with the Guadalupe Island Biosphere Reserve and the Langosteros and Abuloneros cooperative of Guadalupe Island, COBI trained and equipped them to carry out oceanographic monitoring around their island.

Stanford University got involved with the project to install an oceanographic sensor that enables the measurement of environmental variables like pH, temperature and oxygen, among others. This group of women is trained to handle, maintain and collect data from these devices. These sensors belong to a larger network of sensors placed throughout the Pacific coast of Baja California. Data provided by this network of sensors has permitted the detection of regional climate phenomena like hypoxia episodes (low oxygen events at sea) which strongly affect sessile organisms.

In 2013, cooperative members participated in a multi-criteria workshop that addressed the importance of marine recovery zones in their concession area without reaching an agreement on how to implement and monitor them.
