North Pacific circulation

Target entity: North Pacific circulation
Context triple: [Subarctic Current, partOf, North Pacific circulation]

• A. North Pacific subpolar gyre
  The North Pacific subpolar gyre is a large, counterclockwise-rotating system of ocean currents in the northern Pacific that strongly influences regional climate, marine ecosystems, and heat and nutrient transport.
• B. North Pacific western boundary current system
  The North Pacific western boundary current system is a major ocean circulation feature comprising strong poleward and subpolar currents along the western edge of the North Pacific that play a key role in regional climate, heat transport, and marine ecosystems.
• C. North Pacific Current
  The North Pacific Current is a major eastward-flowing ocean current in the North Pacific that forms part of the North Pacific Gyre and helps distribute heat and nutrients across the basin.
• D. Arctic Ocean circulation
  Arctic Ocean circulation is the system of currents and water movements in the Arctic Ocean that redistributes heat, freshwater, and sea ice across the polar region and connects it to the global ocean.
• E. North Pacific Ocean–Bering Sea interface
  The North Pacific Ocean–Bering Sea interface is the transitional marine zone around the Aleutian Islands where waters from the open North Pacific mix with those of the semi-enclosed Bering Sea, creating a highly dynamic and biologically productive environment.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
