| The hydrological properties and circulation along the TIP ( Transport Indian Pacific) section between Java and Australia in September 2000 at the end of the southeast monsoon season are described. It is a reoccupation of the JADE ( Java Australia Dynamic Experiment) sections carried out in August 1989 and in February 1992, which encompass the throughflow between the Pacific and the Indian oceans. The net geostrophic transport in September 2000 is of the same order as the August 1989 estimate. The results from the three occupations reveal that the seasonal and inter-annual variability is predominant and during the three cruises the transport evaluations capture the largest variability of the throughflow. |

| Satellite altimetry is used to study the propagation pathways of warm and cold ocean eddies in different ocean basins. We consider eddies that have a life span longer than 3 months, and we present three regional studies: in the southeast Indian, the southeast Atlantic, and the northeast Pacific Oceans. The case studies show that simple theories for vortex propagation on a beta-plane work in regions where energetic eddies propagate though a weak background flow. Under these conditions, anticyclonic/cyclonic eddies propagate westward and equatorward/poleward. This divergence in the eddy pathways implies a net equatorward eddy heat flux, and has implications for the meridional transport of freshwater, carbon, nutrients, etc. |

| Continuous surface temperature and salinity measurements have been collected onboard a supply ship between Tasmania and Dumont D'Urville, Antarctica, as part of the SURVOSTRAL program (Surveillance de l'Oce'an Austral). The ship makes 6-10 repeat sections per year from October to March for the period 1993-1999, and these measurements form the longest time series of spring and summer variations available in the Southern Ocean. The surface fronts are more clearly indicated with the salinity data than the temperature data. The Levitus climatological and Reynolds satellite monthly mean sea surface temperature data compare well with our surface temperature data: All data sets are dominated by the large-scale seasonal heating cycle with similar amplitude and... |

| The SEMAPHORE mesoscale air/sea experiment was conducted in the Azores-Madeira region from July to November 1993. TOPEX/POSEIDON (T/P) and ERS 1 were flying simultaneously at that time. The main purposes of this paper are to evaluate the estimation of the oceanic mesoscale circulation from the two different sets of altimetric data (T/P and ERS 1) and to compare the results with in situ measurements provided by the SEMAPHORE hydrographic surveys and surface drifters (three expendable bathytermograph conductivity-temperature-depth surveys in a 500-km(2) box and a set of 47 Lagrangian surface drifters drogued at 150 m). Comparisons are carried out through the maps obtained by objective analysis from the four data sets. The mapping accuracy of T/P, ERS 1, T/P... |
