Thermohaline Data and Océan Circulation on the Ross Sea Continental Shelf

Table 1. A chronological summary of océan stations with température and salinity data
on the Ross Sea continental shelf, from 1928-1929 to 1996-1997. In this compilation each
season (year) begins on 1 June (month 1). Identified data sets for which the stations hâve
yet to be merged with this file appear as blanks under Stations. Most ship data are available from the National Océanographie Data Center, and some also in data reports (e.g.,

Data quality and seasonal cycles are important issues in studies of Coastal
régions. We hâve long been aware of apparently large (> 0.15) salinity changes
from one summer to the next in the deep shelf water of the Southwest Ross Sea
[19]. While these changes exceeded the measurement accuracy by an order of
magnitude, they seemed confounded by a year-round sériés of station measurements taken through the sea ice in McMurdo Sound (Fig. 2). Extending to depths
exceeding 500 m, the températures showed relatively little variability, but the
salinities displayed a greater range than the interannual summer changes noted
above. As in the summer profiles [19], temporal shifts were simultaneous over
