Abstract：North Pacific Intermediate Water(NPIW)is the largest water mass that originates in the North Pacific Ocean,and the process of NPIW formation acts as the only channel that links surface and the deep water in the North Pacific.Within the atmosphere-ocean coupled system,vertical mixture and ventilation process associated with NPIW circulation plays critical roles in changing marine carbon cycle and marine ecosystem,thus important to understand the global warming and its future projection.Physical oceanographic studies of NPIW have been performed mainly since the 1970s.Most of existing studies about NPIW rely on cruise section and CTD data,in combination of numerical simulation.In this work,we provide a review about the studies about the modern NPIW to constrain the problems and prospects:To characterize a tendency and variability across Seasonal,interannual and decadal time scales in the modern NPIW;To explore physics of NPIW in response to atmosphere and upper ocean processes;To explore stability of NPIW and its feedback to the global warming.
