  1. NINJA (TSK) float – recent operationToshio Suga (JAMSTEC / Tohoku Univ.) • 7 profiling floats with oxygen/chlorophyll sensors were funded by Japanese Fisheries Research Agency and deployed in March-May 2008. • 3 floats were NINJA floats. • 40-db parking depth following mixed layer • 500-db profiling with 5-day interval • Wetlabs FLNTU sensor with TSK shutter • Data compression enabling data transmission from >200 levels through ARGOS • 2 floats and their FLNTU sensors are still working properly almost after one year from deployment.
