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.

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

Sustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

Block-FFT Based OMP for Compressed Channel Estimation in Underwater Acoustic Communications

, 2015
Due to the sparsity in the delay-Doppler domain of the underwater acoustic (UWA) channel, compressed channel estimation (CCE) can effectively reduce the required number of pilots, which is desirable for low bit-rate underwater acoustic communications ...
