the results ( section 4 ). 2. Data CTD profile data collected by Argo floats are used in this study. Data collected from 1999 through February 2009 were downloaded from an Argo global data center (GDAC) in February 2009. Delayed-mode quality controlled data (adjusted values) are used where available. Otherwise, real-time quality controlled data (raw values) are used. Only data at pressures where pressure ( P ), temperature ( T  ), and salinity ( S  ) are all flagged as good (Argo quality flag 1

contrast in surface salinity between the Pacific and the Atlantic that prevents deep sinking in the North Pacific ( Weyl 1968 ; Warren 1983 ). In the North Pacific, surface water is fresher and lighter than the deep water, which is close to the mean deep-water salinity of the World Ocean. However, the salinity contrast in itself provides no satisfying process-based explanation, and there are diverging ideas of why this contrast arises. Several hypotheses have been proposed to explain the asymmetry in

and tuned with data for wind speeds up to 20 m s −1 , I have some confidence that it can be extrapolated up to the lower limits of hurricane-strength winds—say to 40 m s −1 . As spray droplets evaporate, they become increasingly saline. By logically following the concept of reentrant spray droplets mentioned above, we see that these droplets must also constitute an effective salt flux to the ocean when they fall back into the sea. To my knowledge, no one has estimated this spray salt flux before

and freshwater fluxes nor the current skill of the numerical modeling of the ocean is sufficient for realistic simulations of the temperature and salinity. The ocean owes its stratification in large part to surface processes. Therefore, realistic simulation of sea surface temperature (SST) and sea surface salinity (SSS) is crucial for successful modeling of the ocean state, and a choice of surface boundary conditions is often dictated by the need to keep the values of simulated SST and SSS as

( Talley 1991 ). A portion of the newly ventilated NPIW enters the subtropical gyre near the western boundary where the Oyashio and Kuroshio waters meet, interleave, and mix in the broad Mixed Water Region (MWR) between the separated Oyashio and Kuroshio Fronts ( Hasunuma 1978 ; Talley 1993 ; Talley et al. 1995 ; Yasuda et al. 1996 ). Within the North Pacific's subtropical gyre, NPIW is often identified by a salinity minimum at a potential density of σ θ = 26.7–26.8. This salinity minimum is

1. Introduction The Kuroshio Extension is an eastward jet that forms after the Kuroshio separates from the east coast of Japan near the Boso Peninsula. Warm and saline water is transported by the Kuroshio and the Kuroshio Extension ( Fujimura and Nagata 1992 ; Yasuda et al. 1996 ; Hiroe et al. 2002 ). The Oyashio, which is the western boundary current of the subarctic gyre in the North Pacific Ocean, transports cold and low-salinity Oyashio water with low potential vorticity characteristics

salinity as the CMW pycnostads in the permanent pycnocline, extends as far west as 143°E, almost reaching the east coast of Japan. How is CMW subducted from this zonally elongated formation region into the permanent pycnocline? The mechanism is important in determining the CMW properties and causing their variability but has not been well clarified. Numerical models demonstrated that CMW is subducted east of the date line by crossing a sharp front of the mixed layer depth (MLD) at the eastern end of
