Origin of an antifreeze protein gene in response to Cenozoic climate change

Autor: Laurie A. Graham, Sherry Y. Gauthier, Peter L. Davies

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-16 (2022)

Abstract Antifreeze proteins (AFPs) inhibit ice growth within fish and protect them from freezing in icy seawater. Alanine-rich, alpha-helical AFPs (type I) have independently (convergently) evolved in four branches of fishes, one of which is a subse

Convolutional neural network and long short-term memory models for ice-jam predictions

Autor: F. Madaeni, K. Chokmani, R. Lhissou, S. Homayouni, Y. Gauthier, S. Tolszczuk-Leclerc

Publikováno v: The Cryosphere, Vol 16, Pp 1447-1468 (2022)

In cold regions, ice jams frequently result in severe flooding due to a rapid rise in water levels upstream of the jam. Sudden floods resulting from ice jams threaten human safety and cause damage to properties and infrastructure. Hence, ice-jam pred

Combining TerraSAR-X and time-lapse photography for seasonal sea ice monitoring: the case of Deception Bay, Nunavik

Autor: S. Dufour-Beauséjour, A. Wendleder, Y. Gauthier, M. Bernier, J. Poulin, V. Gilbert, J. Tuniq, A. Rouleau, A. Roth

Publikováno v: The Cryosphere, Vol 14, Pp 1595-1609 (2020)

This article presents a case study for the combined use of TerraSAR-X and time-lapse photography time series in order to monitor seasonal sea ice processes in Nunavik's Deception Bay. This area is at the confluence of land use by local Inuit, ice-bre

River predisposition to ice jams: a simplified geospatial model

Autor: S. De Munck, Y. Gauthier, M. Bernier, K. Chokmani, S. Légaré

Publikováno v: Natural Hazards and Earth System Sciences, Vol 17, Pp 1033-1045 (2017)

Floods resulting from river ice jams pose a great risk to many riverside municipalities in Canada. The location of an ice jam is mainly influenced by channel morphology. The goal of this work was therefore to develop a simplified geospatial model

COMPARISON OF C-BAND AND X-BAND POLARIMETRIC SAR DATA FOR RIVER ICE CLASSIFICATION ON THE PEACE RIVER

Autor: H. Łoś, K. Osińska-Skotak, J. Pluto-Kossakowska, M. Bernier, Y. Gauthier, M. Jasek, A. Roth

Publikováno v: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XLI-B7, Pp 543-548 (2016)

In this study, synthetic aperture radar (SAR) data from TerraSAR-X were compared with RADARSAT-2 data to evaluate their effectiveness for river ice monitoring on the Peace River. For several years RADARSAT-2 data have been successfully used for river
