The unique geometry of the Arctic—surrounded [...] the Arctic Ocean with hydrographic observation lines (Figure 1). A method to treat the Arctic as a single box bounded by hydrographic lines and land has been developed recent years. This pan-Arctic approach [...] monitor the major oceanic heat and FW exchanges between the Arctic Ocean and surrounding Oceans?
