Spray Underwater Glider Operations
AbstractOperational statistics for the Spray underwater glider are presented to demonstrate capabilities for sustained observations. An underwater glider is an autonomous device that profiles vertically by changing buoyancy and flies horizontally on wings. The focus has been on sustained observations of boundary currents to take advantage of the glider’

Robust data assimilation in river flow and stage estimation based on multiple imputation particle filter [PDF]
In this paper, new method is proposed for a more robust Data Assimilation (DA) design of the river flow and stage estimation. By using the new sets of data that are derived from the incorporated Multi Imputation Particle Filter (MIPF) in the DA ...

Design and control of hybrid underwater glider
In this article, a design and analysis on 200-m-class hybrid underwater glider actuated by a buoyancy engine and a thruster was studied. The hull shape of the hybrid underwater glider was designed to reduce underwater resistance using Myring hull profile

Data-driven depth-averaged current prediction methods for underwater gliders with sailing parameters
The study of depth-averaged currents is of great significance for the application of underwater gliders. In order to solve the problem of low prediction accuracy of the time series-based depth-averaged current prediction method, the factors affecting the

Range-only underwater target localization : error characterization [PDF]
Locating a target from range measurements using only one mobile transducer has been increased over the last years. This method allows us to reduce the high costs of deployment and maintenance of traditional fixed systems on the seafloor such as Long

Closing the sea surface mixed layer temperature budget from in situ observations alone: Operation Advection during BoBBLE [PDF]
Sea surface temperature (SST) is a fundamental driver of tropical weather systems such as monsoon rainfall and tropical cyclones. However, understanding of the factors that control SST variability is lacking, especially during the monsoons when in situ ...
