%0 Journal Article %T Interannual variations of water mass properties and volumes in the Southern Ocean %A M. Tomczak %A S. Liefrink %J Ocean Science Discussions (OSD) %D 2006 %I Copernicus Publications %X Time-resolving optimum multi-parameter (TROMP) analysis is used to study interannual variability of water mass properties in the Southern Ocean in a section between Antarctica and Tasmania for the period 1991¨C1996. Water mass properties were stable during 1994¨C1996 but showed departures from their 1994-1996 values during 1991 and 1993. TROMP analysis is unable to quantify the interannual variation in detail, but it is shown that interannual variability does not invalidate the findings of a previous study that was based on the assumption of time-invariable water mass properties and suggested large interannual fluctuations in the water mass volumes south of Tasmania. %U http://www.ocean-sci-discuss.net/3/199/2006/osd-3-199-2006.pdf
