Thin light blue lines indicate Jason 1 ground tracks. Solid lines are the GDEM mean surface dynamic height contours in dyn cm from Teague et al. (1990). The 2000 and 4000 m isobaths are shaded dark and light gray respectively. Eddy kinetic energy &gt; 0.18 and 0.23 m<sup>2<\/sup>s<sup>-2<\/sup> is color shaded yellow and orange respectively. CTD\/SADCP observations were made at all CPIES sites.<\/p>\n<hr>\n<p>The moored array was designed to measure the time-varying density and velocity fields with the 4-D mesoscale resolution required to determine dynamical balances and cross-frontal exchanges of heat, salt, momentum, and PV. The high-resolution in situ instrument array was centered on the first quasi-stationary meander trough east of Japan, indicated by the GDEM mean surface dynamic height contours (black in above figure). The array was located in the region of highest eddy kinetic energy (yellow and orange shadings).<\/p>\n<p>The in situ observations spanned a two-year period. The instruments were deployed on a cruise aboard the R\/V Thompson in Spring 2004 <a href=\"http:\/\/www.po.gso.uri.edu\/dynamics\/KESS\/KESS_deployment_summary.html\"> (Deployment Cruise Summary)<\/a>. On a mid-experiment cruise conducted during June-July 2005 aboard the R\/V Revelle, the moored profiler moorings were recycled and their data collected. Daily measurements of pressure, travel time and currents were telemetered to the ship from the CPIES and a CTD\/ADCP feature survey was conducted. The moored instruments were recovered during May and June 2006 on a cruise aboard the R\/V Melville.<\/p>\n<p>Additional information about the KESS cruises, including cruise reports, may be found on the US KESS website under the <a href=\"http:\/\/uskess.whoi.edu\/cruises\/\"> cruises link<\/a>.<\/p>\n<hr>\n<h2>Mapping Array Highlights<\/h2>\n<h3>Two States of Variability<\/h3>\n<p>Satellite altimetry shows the Kuroshio Extension alternates between relatively stable and vigorous meandering intervals on decadal time scales (Qiu and Chen, 2005). The Kuroshio extension transitioned between these two states in fall 2004. SSH fields for the stable period (below left) show two nearly stationary meanders and a westward propagating warm core ring in the KESS region. During the active period (below right), a steep trough develops and a cold core ring forms.<\/p>\n<div id='gallery-1' class='gallery galleryid-156006 gallery-columns-2 gallery-size-medium'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/AvisoP1.jpg' rel=\"lightbox[156006]\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"268\" src=\"https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/AvisoP1.jpg\" class=\"attachment-medium size-medium\" alt=\"\" \/><\/a>\n\t\t\t<\/div><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/AvisoP2.jpg' rel=\"lightbox[156006]\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"268\" src=\"https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/AvisoP2.jpg\" class=\"attachment-medium size-medium\" alt=\"\" \/><\/a>\n\t\t\t<\/div><\/figure>\n\t\t<\/div>\n\n<h3>Upper (contours in cm) and Deep (color in dbar) Mean Streamfunctions<\/h3>\n<p>During the stable period (below left), the upper mean streamfunction shows a well-defined KE front and recirculation gyre SW of a mean weak meander trough. Anticyclonic circulation in the deep streamfunction is the deep expression of the southern recirculation gyre. There is weak cross-frontal flow under the trough. During the active period (below right), there is increased meandering which produces weaker lateral gradients across the KE mean front. Both the trough and cold core ring are evident in the mean. Deep features are intensified during the active period.<\/p>\n<p><a href=\"https:\/\/web.uri.edu\/wp-content\/uploads\/sites\/916\/MeanPrsTaup1p2.jpg\" rel=\"lightbox[156006]\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-156033\" src=\"https:\/\/web.uri.edu\/wp-content\/uploads\/sites\/916\/MeanPrsTaup1p2.jpg\" alt=\"\" width=\"400\" height=\"276\" srcset=\"https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/MeanPrsTaup1p2.jpg 400w, https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/MeanPrsTaup1p2-300x207.jpg 300w, https:\/\/web.uri.edu\/gso\/wp-content\/uploads\/sites\/916\/MeanPrsTaup1p2-364x251.jpg 364w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a><\/p>\n<h3>Mesoscale features alias satellite SSH<\/h3>\n<p>From May to September 2004 (below left, the green hatched area in SSH (m) time series) a series of rapid, eastward propagating (25-30 km\/d) meanders were observed by the CPIES.
