On the east it is connected with the Atlantic Ocean by Hudson Strait; on the north, with the Arctic Ocean by Foxe Basin (which is not considered part of the bay), and Fury and Hecla Strait. Geographic coordinates: 78Â° to 95Â° W, 51Â° to 70Â° N. Hudson Bay is part of the North Atlantic Ocean. Sometimes the Hudson Bay and Hudson Strait basins are considered part of the Arctic Ocean even though their waters flow predominantly to the Atlantic. Some sources describe Hudson Bay as a marginal sea of the Atlantic Ocean, or the Arctic Ocean.
Hypervigilance. Hypervigilance is an enhanced state of sensory sensitivity accompanied by an exaggerated intensity of behaviors whose purpose is to detect threats. Hypervigilance is also accompanied by a state of increased anxiety which can cause exhaustion. Other symptoms include: abnormally increased arousal, a high responsiveness to stimuli, and a constant scanning of the environment for threats.
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time.
