New high resolution density fields for the northwestern Atlantic Ocean are calculated from objectively analyzed temperature and salinity fields obtained from archived data. The original data set is the Marine Environment Data Service (MEDS) archived data and is supplemented by a subset of the National Oceanographic Data Centre (NODC) data from J. Reid and by the 1980s additional data of Fukumori and Wunsch (1991). The objective analysis scheme is a modification of that used by Levitus (1982) and uses 37 vertical levels. The scheme is used to calculate the climatological mean (1910-1989) temperature and salinity fields for the summer and the warm and cold seasons. Inverse methods are then applied to these new density fields in order to determine the transport and circulation during these periods. A study of the seasonal and interdecadal variations of the ocean transport and circulation is also presented. The interdecadal analysis is based on temperature and salinity fields analyzed for the warm season of the 1950-1964 and 1965-1981 periods.
