      1. Folder2014 
        1. PageDec. 2014: Sahelian dry and wet seasons seen by altimetry Altimetry enable to monitor soil moisture in semi-arid areas like Sahel
        2. PageOct. 2014: Better Mediterranean circulation Mediterranean circulation needs a high-resolution. With a new processing, oceanic features are clearly seen.
        3. PageAug. 2014: the Agulhas current leaks The evolution of the Agulhas leakage, and thus of the water exchanges between Indian and Atlantic Ocean has been computed thanks to twenty years of altimetry data
        4. PageJuly 2014: Groundwater from altimetry In the Amazon plain, the groundwater level is about the same than the rivers' and lakes', which can be measured by altimetry
        5. PageMay 2014: Forecasting rivers Combining Jason-2 Ganges-Brahmaputra levels with a forecasting model can lead to forecast water level
        6. PageApr. 2014: Melting in the Kara Sea AltiKa data over the Kara Sea enable to distinguish there the effects of ice melting and also the presence of polylinias.
        7. PageJan. 2014: 35 years of altimetry! Seasat was the first proof-of-concept altimeter which gave real oceanographic data. The Loop Current, among others was observed this way in 1978.
      2. Folder2013 
        1. PageDec. 2013: Mediterranean tides on the move Tides are also measured and predicted in the Mediterranean Sea, with a better and better precision thanks to altimetry.
        2. PageNov. 2013: Typhoon Haiyan seen by Saral Typhoon Haiyan is one of the most powerful typhoon devastating the Philippines. It reached the coast on November 7. Saral/AltiKa overflew the typhoon on pass 821 on November 7 21:30 UTC.
        3. PageOct. 2013: salt and temperature vs altimetry Ocean surface heights measured by altimetry reflect the density of the waters, which is a matter of salinity and temperature.Using SMOS satellite surface salinity and SST, a surface density can be computed, and compared with altimetry sea surface heights.
        4. PageSep. 2013: Icebergs on the move Having twenty years of altimetry enables to compute statistics on icebergs including a climatology of icebergs shed by the Antarctic continent.
        5. PageAug. 2013: 20 years of typhoons Tropical cyclones are known to be intensified by the heat of the upper ocean. Sea surface heights from altimetry enable to have an insight on e subsurface warm layer thickness and upper ocean heat content and their variations over the last two decades.
        6. PageJul. 2013: Ob bogs and wetlands Saral is giving very promising results, especially for wetlands and more generally inland waters. The measurements over the Ob basin area are providing with a mean to discriminate between water, ice and dry lands.
        7. PageJun. 2013: Is the ground rising or the sea decreasing? Tide gauges are used to monitor sea level. However, they are anchored on lands, and thus monitor as much the land vertical motions than the sea's. When tide gauges and Doris stations are close by, combining their measurements enables to decide if it is the land or the sea which varies.
        8. PageMay 2013: Drifting buoy The Acciona sailing boat capsized on February 3 at the end of last Vendée Globe alone-the-world sailing race. One of the onboard Argos beacons got loose and switched on. It has been followed ever since by the Argonautica educational project.
        9. PageMar. 2013: Saral: 6 days old, and already measuring The Saral satellite was launched on February 25, 2013. A little more than one week after its launch, the data looks very promising. Next is the continuation of measurement analysis, validation of ground processing software and a calibration/validation phase with the PIs.
        10. PageFeb. 2013: Alboran Sea eddies Alboran Sea is at the entrance of the Mediterranean Sea. Atlantic waters enters the Mediterranean turbulently, leading to a pair of eddies with varying intensity that show as well in altimetry as in other kind of ocean observation from space.
        11. PageJan. 2013: Salinity gets finer with altimetry SMOS satellite (ESA) sea surface salinity were merged with surface geostrophic velocities from altimetry, to identify the best area for an oceanographic field campaign.
      3. Folder2012 
        1. PageDec. 2012: Winds and currents around India India has a climate much influenced by the ocean. The knowledge of currents is thus of foremost importance for the whole country. Using the full twenty-years time series of altimeter data enables to correlate winds and currents with a great confidence.
        2. PageNov. 2012: Arctic trends Dedicated processing enable to access to sea level anomalies over the Arctic ocean (when not iced), and monitor their variations.
        3. PageOct. 2012: Accelerated eddy shedding Agulhas and Agulhas retroflection eddy shedding in the Atlantic seems to be increasing during the last sixteen years, with a possible link with climate variations.
        4. PageSep. 2012: Getting smaller details  The merging of multiple altimeter missions improves the resolution of altimetry-derived maps. However, in some regions like the Mediterranean, even more processing, and inclusion of other kind of data are needed to reach enough resolution.
        5. PageMay 2012: Jellyfish on the move Jellyfish are carried by ocean currents. Altimetry enables to describe those and, with coastal processing, to help forecast jellyfish strandings on the Mediterranean beaches.
