Github Tektronica Profiling Float This paper presents the design and fabrication of a profiling float primarily used for thermocline observations and tracking, with an emphasis on depth control performance. We introduce a simplified dynamical model of the float and propose a state feedback depth controller coupled with an extended kalman filter (ekf) to estimate model parameters. we show experimental results of the depth control that validate the model and the controller.
Profiling Float Technology Improvements Tpos This document describes some initial ideas for the design and implementation of argo, a global array of autonomous profiling floats. Scientists studying the characteristics of the ocean would ideally like to be able to collect data at all depths and all times at a particular location. obviously, a single float cannot be at all depths at all times and therefore must profile to collect data across the depths. The neutrally buoyant floats periodically change their buoyancy by pumping the hydraulic fluid from an internal reservoir to an external bladder, thereby increasing float volume and buoyancy, so repeated measurements can be achieved, and the volume of the float was reduced a lot at the same time. The deflation of the bladder, via an hydraulic actuator, makes the float sink and the reverse makes it ascent. the only energy used is the one of the pump that enables the oil to move from the inside reservoir to the outside bladder (ascent) and vice versa (descend).

The deep sea self sustaining profiling float is widely applied to the argo project 5, and is called a profiling float or argo float, which dives and ascends by altering its buoyancy. In this article, we will delve into the scientific principles and technological advancements that enable profiling floats to collect high quality data, and explore the insights gained from their deployments.
