Popis: This paper presents a new underwater vertical profiling float with anchoring mechanism to embed in the seabed during adverse tidal conditions and navigate in coastal currents with minimal energy consumption to achieve extended periods of deployment. The profiling float has been built with industrial PVC pipes to maintain low cost of production and has been rated to operate at depths of 100m and has been tested in the northern coast of Singapore. Vertical profiles of temperature and depth are obtained from pre-programmed missions. Two configurations were developed; one with multiple chambers with weight changing capability and second with stacked profile and oil bladders where buoyancy control is achieved through volume change. This vehicle serves as a workhorse for measuring salinity, temperature, conductivity, and other parameters aiming at reliable, robust and long term environmental sensing in the coastal regions of Singapore.
