KnowraGulf of ObGulf of ObThe Gulf of Ob is a long, shallow inlet of the Kara Sea in northwestern Siberia, formed by the Ob River estuary.BriefConnectOb River: A major West Siberian river that flows north into the Kara Sea through the Gulf of Ob. Its freshwater flow and sediment form the estuary at the gulf’s southern end.Estuary: A coastal water body where river freshwater mixes with seawater. The gulf is an estuarine transition between the Ob River and Kara Sea.Northern Sea Route: A shipping route through Arctic waters along Russia’s northern coast. The gulf’s connection to the Kara Sea places it near this Arctic passage.Arctic amplification: The tendency for the Arctic to warm faster than the global average. Rapid regional warming changes sea ice and conditions around the gulf.Kara Sea: A marginal sea of the Arctic Ocean north of Siberia. The gulf is a shallow inlet of this Arctic sea.River plume: A spreading body of river water that enters a larger water body and differs in salinity and sediment content. The Ob’s outflow spreads into the Kara Sea through the gulf.Sabetta: A port and industrial settlement on the Yamal Peninsula in northwestern Siberia. Its port serves liquefied natural gas exports near the gulf’s western shore.Climate change in the Arctic: Long-term shifts in Arctic temperatures, ice, ecosystems, and weather patterns. These changes affect the gulf’s ice season and coastal environment.Yamal Peninsula: A peninsula in northwestern Siberia between the Kara Sea and the Gulf of Ob. Its eastern coast bounds much of the gulf’s western side.Sea ice: Frozen seawater that forms, moves, and melts across polar and subpolar oceans. Seasonal ice cover limits navigation and influences exchange with the Kara Sea.Show all 20Linked from 3 pagesObBroader topic: The Ob empties into this Arctic estuary.Gyda PeninsulaRelated: This gulf bounds the peninsula on its western side.Show all 3
