Randy Scharien, Associate Professor, ICE-lab Director
Randy Scharien (PhD University of Calgary, Microwave Remote Sensing) is an expert in the microwave remote sensing of the cryosphere and the impacts of changing climate on sea ice. He joined the Department of Geography, University of Victoria in 2014. Prior to that he was a European Space Agency Changing Earth Science Network investigator (2013-2014). He uses in situ, airborne, and satellite remote sensing to study the changing cryosphere, with emphasis on atmosphere-sea ice-ocean interactions. He has conducted field research at several high latitude locations, including the Canadian Arctic, the European Arctic, and Antarctica.
Parnian Rezania, PhD Student
Parnian (MSc. in Geological Remote Sensing, Azad University of Isfahan, Iran) conducted master’s thesis research on the application of remote sensing data in groundwater exploration. She employed optical remote sensing data, elevation data (Aster DEM), as well as several hydrological and geophysical methods to identify potential well locations in the Borkhar area in central Iran. Parnian began a PhD project focused on Arctic sea ice hazard monitoring using satellite remote sensing data in the fall of 2017.
Aikaterini (Katia) Tavri, PhD Student
Katia is a PhD student in Microwave Remote Sensing, working on sea ice classification using Synthetic Aperture Radar (SAR) data. Her research aims to evaluate the use of polarimetric SAR features for assessing the contribution of scattering mechanisms for sea ice type discrimination and evolution. Katia’s main focus is on the upcoming launch of the RADARSAT Constellation Mission (RCM) in 2018, which establishes a new era for SAR based Arctic marine environmental monitoring.
Trevor Dickinson, MSc Student
Trevor’s MSc thesis research is focused on the estimation of snow depth and snow water equivalent using remotely piloted aircraft systems (RPAS). He is conducting research in the Russell Creek watershed region of northern Vancouver Island. This project is in collaboration with the Coastal Hydrology & Climate Change Research Lab led by Dr. Bill Floyd.
Vishnu Nandan, Post-Doctoral Scholar (2018-2019)
Vishnu’s post-doctoral research focused on understanding the critical role of snow cover impacting sea ice thickness retrievals from radar satellites. as well as preparation activities for ICE-lab participation in MOSAiC.
Rebecca Segal, MSc Student (2017-2019)
Becky’s MSc research combined remote sensing and traditional knowledge to make sea ice information products of interest to residents in the Kitikmeot region of Nunavut, western Canadian Arctic. She uses interviews with community members to inform and guide the analysis of Synthetic Aperture Radar (SAR) images. I am using current SENTINEL-1, COSMO-SkyMed, and ALOS-2 PALSAR-2 imagery as well as a 20-year archive of RADARSAT 1/2 images to understand how community relevant parameters derived from archived imaging radar data can benefit people who live and travel in the Arctic. Her project is partnered with the Canadian Ice Service, the Ice-Covered Ecosystems – CAmbridge Bay Process Studies (ICE-CAMPS) group, Ocean Networks Canada, and the Arctic Eider Society (SEA-AES).
Silvie Cafarella, MSc Student (2017-2019)
Silvie’s research focused on the use of satellite synthetic aperture radar as a sea ice monitoring tool in the Arctic. The main goal of Silvie’s project is to improve remote sensing techniques to detect, classify, and derive geophysical parameters of sea ice features in the Canadian Arctic Archipelago. Her research is focused on the use of remote sensing technology for natural hazard mapping, assessment, and mitigation.
Sasha Nasonova, MSc Student (2015-2018)
Sasha’s thesis research investigated linkages between the extent of melt ponds on sea ice to winter (pre-melt) sea ice roughness and thickness, for improved understanding of sea ice structure and melting processes. Her work contributed to the growing body of literature on the parameterization of melt pond fraction in sea ice-climate models. She also investigated the utility of polarimetric synthetic aperture radar parameters for distinguishing major sea ice types (first-year ice, deformed first-year ice and multiyear ice) during the advanced melt season. This research contributes to improved satellite based sea ice awareness for safe marine navigation and ecosystem preservation through disaster prevention.
Trilby Buck, Undergraduate Honours Student (2017-2018)
Trilby’s honours thesis used time series analysis to look at changes in arctic sea ice melt and freeze up, in regards to community sea ice travel safety. Her project determined and reported on the changes of sea ice cover melt onset, pond onset, break up and freeze up (a sea ice phenology) as it relates to informed and safe sea ice use by community members in the Kitikmeot region of Nunavut, in the Western Canadian Arctic. Identification of seasonal changes in melt and freeze using remotely sensed imagery will were emphasized as it relates to community needs. Time-series data were derived from MODIS for the years 2000-2017. Findings were related to changes in sea ice use by the communities, and shared directly to members of Cambridge Bay and Kugluktuk in spring 2018 .
