Microphysics and interactions of aerosols and fog on the northwest Atlantic Ocean

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In the Grand Banks, aerosol size distributions were bimodal, aerosol and fog droplet concentrations were low, and fogs were shorter (<12 hours). In contrast, near Sable Island, aerosol size distributions had a single broad mode that was likely influenced by continental emissions, corresponding with higher aerosol and droplet concentrations as well as ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch (Macquaria ambigua)

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch (Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin.

Development and Assessment of Fluorescent‐Dyed, Preserved Invasive Grass Carp (Ctenopharyngodon idella) Eggs as Surrogates for Live Eggs in Transport and Dispersal Control Experiments

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Invasive species such as grass carp (Ctenopharyngodon idella) pose substantial ecological threats to North American freshwater ecosystems. Understanding their early life stage behavior is critical for management efforts. From spawning to hatching, invasive carp eggs must remain suspended in the water column while drifting downstream for the ...

Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with
