Safety Inspections and Gas Monitoring in Hazardous Mining Areas Shortly After Blasting Using Autonomous UAVs

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This article presents the first ever fully autonomous UAV (Unmanned Aerial Vehicle) mission to perform gas measurements after a real blast in an underground mine. The demonstration mission was deployed around 40 min after the blast took place, and as such realistic gas levels were measured.

Longitudinal Variability in the Oxygen Demand of Channel Bed Matrix Sediment in a UK Agricultural Catchment: Implications for Managing the Sediment Problem

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The presence of excess fine‐grained matrix sediment in channel beds can exert an oxygen demand in this critical habitat for fish spawning and invertebrates. Therefore, reducing the oxygen demand of channel bed sediment through targeted intervention may deliver better cost–benefit from catchment management.
