The article describes the climate and oceanography of the Bering Sea and presents a summary of the Bering Sea Project. It states that the eastern Bering Sea shelf had relatively cold weather from October 2012 until March 2013. This period encompassed an anomalously weak Aleutian Low which generally means suppressed storminess, which in turn means a lower than normal incidence of relatively warm air masses of maritime origin as against colder air of Arctic or continental origin.
