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

( 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

. Model development Here a mathematical model of tidally averaged, width-averaged estuarine salinity structure in a rectangular channel of varying cross section is developed. The numerical solution to the equations is developed in this section, and approximate analytical solutions are developed in section 4 . The model is tested against observations in section 3 . The model is basically a time-dependent version of the Hansen and Rattray (1965) equations, and I attempt to make it a better

ice and atmosphere by a cap of fresh, cold surface water bounded below by a strong pycnocline (e.g., Rudels et al. 1996 ) in which salinity increases from near-surface values of 33 or lower to around 34.5 at 150–300-m depth. At the same time, the decrease of AW temperature with increasing distance from Fram Strait implies that AW heat must be lost as the AW spreads. Much of this heat is spread laterally by advection, eddy stirring, or other processes, but some portion is lost upward to the

1. Introduction A variable called spiciness was introduced three decades ago in order to characterize water masses and intrusions ( Munk 1981 ; Jackett and McDougall 1985 ). Water masses can either be characterized by their temperature and salinity or by their spiciness and density. To a first-order approximation a spiciness anomaly (noted d π ) along a given time-varying surface of constant potential density referenced to the surface pressure (called isopycnal surface and noted as σ ) is a

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
