Abstract

First time in the Indian ocean, Underway Conductivity-Temperature-Depth (UCTD) instrument was used measure the upper ocean thermo-haline strucuture with 500 m spatial resolution. The UCTD system was installed onboard ORV Sagar Nidhi and operated in the Bay of Bengal region during November-December 2013. While Argo float may provide the vertical structure at one place and drift according to the current, UCTD provide vertical structure with a spatial resolution of 100 m, if we operate in the top 150 m water column. Around 190 profiles with a spatial resolution of 500m and vertical resolution of 0.25 m temperature and salinity upto 150 m were acquired during this pilot cruise which was dedicated to characterize and study the upper ocean sub-mesoscale (1-10km) variability in the Bay of Bengal. The acquired data processed using standard Matlab tools and compared with onboard Thermosalinogrph
