1. Introduction One of the expected consequences of global warming is the modification of the water cycle, one of the main forcing mechanisms of the ocean thermohaline circulation. In actuality, freshwater fluxes have a local influence on the surface salinity, and thus on the ocean dynamics. Josey and Marsh (2005) show that sea surface salinity has been modified since the mid-1970s because of increased precipitation in the North Atlantic Ocean subpolar gyre. Modification of ocean salinity in

ice-free months is 32 km, whereas the mean distance between each consecutive pair of interpolated positions during the ice-covered months is only 13 km. Nonetheless, this simple method of estimating position under ice is sufficient for regional studies such as this one. This study used 1964 quality-controlled CTD profiles that were located within the seasonal sea ice zone. Of the 1964 profiles, 1128 (57%) were collected under sea ice. Float salinity measurements were checked for conductivity

goals: define the mean temperature and salinity properties of the DWBC and estimate timescales and magnitudes of its variability; determine the type of changes in temperature and salinity structure responsible for the variability between pairs of sections. The first goal is addressed in section 3 with mean properties described in 3a and variability in section 3b . Transect differences by depth and density are shown in section 4 . A method developed by Bindoff and McDougall (1994) is used in

. The halocline in the surface layer occurs when the surface salinity is reduced significantly, compared to the subsurface layer by processes such as excess precipitation over evaporation, river runoff, and redistribution of the low-salinity water by horizontal advection. These low-salinity water fluxes can act in concert, as in the Bay of Bengal ( Thadathil et al. 2007 ), or individually, as, for example, in the western Pacific, where high precipitation is accompanied by westerly wind bursts, the

1. Introduction Eddies are known to be a common feature of the Canada Basin halocline having been observed in many past studies ( Newton et al. 1974 ; Hunkins 1974 ; Manley and Hunkins 1985 ; D’Asaro 1988a ; Padman et al. 1990 ; Plueddemann et al. 1998 ; Münchow et al. 2000 ; Muench et al. 2000 ; Krishfield et al. 2002 ; Pickart et al. 2005 ). The halocline layer lies above about 250-m depth in the Canada Basin and is characterized by a strong increase in salinity with depth and

1. Introduction Three typical high-salinity water masses have been reported in the Arabian Sea: the Arabian Sea high-salinity water (ASHSW), the Persian Gulf water (PGW), and the Red Sea water ( Morrison 1997 ; Rochford 1964 ; Stramma et al. 2002 ). The ASHSW forms in the northern part of the Arabian Sea and spreads southward as a salinity maximum within the upper 150 m ( Kumar and Prasad 1996 , 1999 ; Qasim 1982 ; Rochford 1964 ). The PGW forms in the Persian Gulf and exits to the Gulf of

1. Introduction As a part of attempts to manage and restore the San Francisco Estuary, environmental standards have been based on the positioning of the salt field in northern San Francisco Bay and the adjoining delta of the Sacramento and San Joaquin Rivers (see Fig. 1 ). Following a suggestion by Williams and Hollibaugh (1989) , the measure of salinity intrusion proposed by the Environmental Protection Agency (EPA; Schubel et al. 1992 ), and eventually implemented, was X 2 —the distance
