The Benguela Current System</a> </span><br> One of four eastern boundary upwelling systems, the Benguela is highly productive and supports one of the world's richest fisheries. Using the Benguela as an example, the lesson shows how data from MERIS, AATSR and other sensors are used to study the physical and biological processes characteristic of coastal upwelling regions. <span class=ssbk> &nbsp; &nbsp; <br>Authors: F.Shillington, S.Bernard, N.Chang, University of Cape Town, ZA, with V.Byfield, NOC. </span> </p> </td> </tr> <tr> <td> <img src="img/t.gif" height=5><br><img src="img/l6_thumb.jpg" width=110 height=105 border=1> </td> <td> <p> <span class=bold> <a href="../l6_oe/start.html" name="l6"> L6. Ocean eddies </a> </span><br> Eddies can cause large changes in current speed and direction over small areas, and are one of the main mechanisms for mixing water from different sources. The lesson shows how measurements of sea surface temperature (SST) and height (SSH) from Envisat and other satellites are used to study these highly dynamic features. <span class=ssbk> <br>Authors: D.McNeall and V.Byfield, National Oceanography Centre, Southampton, UK. </span> </p> </td> </tr> <!-- <tr> <td> <img src="img/t.gif" height=5><br><img src="img/l7_chris55s_s.jpg" width=110 height=105 border=1> </td> <td> <p> <span class=bold> <a href="../l7_sgp/start.html" name="l7" > </a>L7. Surface glitter patterns in the Ocean </span><br> Sea surface roughness and sun-glitter patterns can reveal thin films of organic material on the sea surface. SAR is now used to monitor oil spills, but caution is necessary to avoid false positives.

Determining rain rate at sea </span><br> The ocean holds 98% of Earth's water. Exchange with water vapour in the atmosphere is a key part of the global hydrological cycle and a powerful factor in our climate system. The lesson looks at efforts to detect rainfall at sea by combining cloud-top measurements from AATSR with data from RA-2 and the MWR radiometer. <span class=ssbk> <br>Authors: G.Quartly, and V.Byfield, National Oceanography Centre, Southampton, UK. </span> </p> </td> </tr> --> </table> <table width=620> <!-- BOTTOM LINE //--> <tr><td><img src="html/img/t.gif" width=1 height=10></td></tr> <tr><td class=blue><img src="html/img/t.gif" width=1 height=1></td></tr> <tr><td><img src="html/img/t.gif" width=1 height=2></td></tr> </table> <table width=620 cellpadding=0 cellspacing=0 border=0> <tr> <td width=120> &nbsp; <a href="http://earth.esa.int/envisat" target="new"> <img src="../html/img/logo_esa.gif" alt="Link to ESA's Envisat website" border=0> </a> </td><td class=right width=155> <a href="http://www.noc.ac.uk" target="new"> <img src="../html/img/logo_noc.gif" alt="Link to NOC's website" border=0> </a> </td> </tr> </table></div> </body> </html>
