The surface diurnal warm layer in the Indian Ocean during CINDY/DYNAMO [PDF]

, 2014
A surface diurnal warm layer is diagnosed from Seaglider observations, and develops on half the days in the CINDY/DYNAMO Indian Ocean experiment. The diurnal warm layer occurs on days of high solar radiation flux (>80 W m-2) and low wind speed (

Glide performance analysis of underwater glider with sweep wings inspired by swift

Frontiers in Marine Science, 2022
Underwater glider (UG) is one of the most promising autonomous observation platforms for long-term ocean observation, which can glide through seawater columns by adjusting its buoyancy and attitude. Hydrodynamic shape, especially the wing parameters, has

Autonomous Underwater Gliders

, 2009
Autonomous Underwater Vehicles are only now being marketed as robust commercial vehicles for many industries, and of these vehicles underwater gliders are becoming the new tool for oceanographers. Satellites have provided scientists and marine specialists with measurements of the sea surface such as temperature since the late 1970s, and data via ...

Improving the energy efficiency of autonomous underwater vehicles by learning to model disturbances [PDF]

, 2013
Energy efficiency is one of the main challenges for long-term autonomy of AUVs (Autonomous Underwater Vehicles). We propose a novel approach for improving the energy efficiency of AUV controllers based on the ability to learn which external disturbances ...

Antarctic krill likely avoid underwater gliders

Deep Sea Research Part I: Oceanographic Research Papers, 2022
Abstract The extent to which marine species avoid survey vessels is the subject of considerable debate, with stimuli such as noise and pressure waves receiving particular attention. By some estimates, avoidance behaviour is a major bias in the assessment of pelagic species distribution and density. Surveyors of the marine environment are increasingly

Experimental application of gliders communication system in South China Sea

Frontiers in Communications and Networks
Utilizing the motion characteristics of underwater gliders, a water acoustic communication system based on heterogeneous gliders was designed. The system consists of a surface wave glider and an acoustic underwater glider, which are respectively equipped
