Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Organizational Soundscapes and the Sonicity of Voices: The Power of the ‘Sounds’ that Carry ‘Words’

Journal of Management Studies, EarlyView.
Abstract Organizations are soundscapes – they resonate with sounds and particularly the sounds of voices. Somehow however voice sonics, that is the sounds of voices and not the words carried on those sounds, have escaped attention in management studies. This absence of analysis is peculiar given voice sonics' undoubted influence on management (they may
