Glider tracks overlaid on satellite chlorophyll and salinity for the equatorial crossings.

<p>The glider tracks for <i>Papa Maru</i> and <i>Benjamin</i> are shown overlaid on (a) VIIRS chlorophyll for July 2012 and (b) Aquarius SSS for July 2012. The glider tracks are color coded by the value for glider fluorescence and salinity. The first day of each month is shown as a large white diamond, the fifteenth of the month is shown as a smaller white diamond. <i>Benjamin</i> followed a path along 170°W, while the <i>Papa Mura</i> took a more western route. (c). chl fluorescence (relative units) overlaid on salinity tracks as a function latitude. Longitude is color-coded for the salinity tracks for reference to panel (b). The <i>Papa Mau</i> salinity track is labeled, the <i>Benjamin’s</i> salinity track overlays this until ∼1°S and is not labeled due to space constraints.
