We present here the first evidence of photodesorption induced by low-intensity non-resonant light from an yttrium thin foil, which works as a neutralizer for Rb and Fr ions beam. Neutral atoms are suddenly ejected from the metal surface in a pulsed regime upon illumination with a broadband flash light and then released in the free volume of a pyrex...

Observation of the climate and ecosystem of ice covered polar seas is a timely task for the scientific community. The goal is to assess the drastic and imminent changes of the polar sea ice cover induced by climate change. Retreating and thinning sea ice affects the planets energy budget, atmospheric, and oceanic circulation patterns as well as the...

Marine protected areas contribute to mitigating the effects of human activities on marine ecosystems. The waters of Southampton Island, Nunavut, Canada are under consideration to become a marine protected area, but baseline information of marine mammal presence and habitat use is lacking. This study represents the first passive acoustic monitoring...

Protected areas are a valuable tool for ecosystem conservation and climate change mitigation. Establishing marine protected areas (MPAs) is especially important in the Arctic, where rapid environmental and human-induced changes are threatening marine mammals. The waters around Southampton Island are experiencing sea ice loss and an increase in vess...

Monitorage acoustique passive des mammifères marins dans l’Arctique canadien : implications d’un Arctique en mutation pour leurs populations et l’utilisation de leur habitat Ma thèse en 180 secondes - Finale nationale 2021

The marine areas around Southampton Island in Hudson Bay, Canada, represent ecological hotspots for many marine mammal species listed as Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). They are home to the Central-Low Arctic walrus (Odobenus rosmarus), and they encompass important migration routes for many...

A 3 minute explanation in plain language of my PhD project on the impacts of underwater noise on marine mammals in the Arctic. Presented as part of the 2021 3 Minute Thesis (3MT) competition finals of the University of Manitoba.

Passive acoustic monitoring technical report for the Arctic Region Marine Environmental Quality program of Fisheries and Oceans Canada (DFO-MPO). Hudson Bay is one of the most southern regions of the Arctic, surrounded by many industrialized areas. Its geographical position is one of the reasons why it is losing sea ice so rapidly. Less sea ice a...

Sea ice plays a major role in the global climate as it represents the interface between the ocean and the atmosphere and thus is of great importance for the energy budget of the whole planet. Climate change has caused a significant rise in air temperature during the last decades that has led to a rapid sea ice decline. Until now, sea ice retreat an...

Research at the ice-water interface below drifting sea-ice is crucial for the investigation of the fluxes of energy, momentum, and matter across the atmosphere-ice-ocean boundary. Transmission of solar energy through the ice and snow layers causes warming of the upper ocean and melting of the ice itself. It is also a key factor for in and under-ice...

In recent years a growing interest has been dedicated to the connection of optical phenomena with fundamental aspects of matter, such as Atomic Parity Non-Conservation (APNC) and accurate measurement of the Electron Dipole Moment (EDM). As a consequence, the demand for techniques able to produce atomic samples with adequate density, high stability...
