The San Jorge Gulf (Golfo San Jorge; Spanish for Gulf of St. George) is a bay in southern Patagonia, Argentina. It is an ocean basin opening to the Atlantic. Its shoreline spans Chubut and Santa Cruz province. The gulf measures approximately at its mouth and covers approximately . It is located between Cape Dos Bahías and Cape Tres Puntas. Due to its geography, more than 70% of the gulf's basin is between and deep. To the south it is about deep and in the north . The seabed was formed by bivalves and cirripedial remains, and it consists of mud, sand, gravel, and sand with carbonate. The mean water temperature varies between and ; salinity is around 33000 ppm. Population centers Approximately 90% of Chubut Province's inhabitants live on the coast of the gulf. Comodoro Rivadavia and Caleta Olivia are two larger cities along the coast. Each having ports with oil buoys and fishing facilities. The fishing towns of Camarones and the seaside resort Rada Tilly also lie along the gulf. Industrial production Fishing activities Comodoro Rivadavia is ranked within the national and international market as a center of lobsters and spider crabs. Numerous fishing ports function along the bay, as with wharves and marinas for sport fishing and related activities. Industry There is a very good quality metallurgy industry along the bay, much of it related to oil exploration and extraction. The non-conventional resource of a wind farm which provides energy is in its first stages of testing, and once passed, the system will totally be integrated to the main network. Mining The petroleum industry, based on value, is the most important activity along the bay. Oil was discovered here in 1903, and the area remains the nation's second most significant source of oil. The city of Comodoro Rivadavia is the hub of these activities along the bay, including refineries and other development and manufacturing facilities. The typical shape of pumping equipment, commonly named "Pumpjack," can be seen along much of the plateau of Patagonia. These wells productions supply a large percentage of the national consumption, which has hovered around half a million barrels daily since the 1970s. Energy The production of oil and gas in the San Jorge Gulf covers 5% of the area's economy. The region is also working on alternative sources of energy such as wind power, hydrogen-based energy and a very incipient activity in the
