Arctus is composed of highly qualified personnel (HQP) with a solid background and experience in both theoretical and practical aspects of remote sensing applied to ocean, coastal and inland water environments, and particularly to polar environments. Domains of expertise comprise the development of algorithms and numerical models for the exploitation of Earth Observation data produced by various space agencies.

Simon Bélanger, Ph.D.

Scientific Director

Arctus scientific director, is a professor in remote sensing at the Université du Québec a Rimouski (UQAR). He has more than 20 years of experience in the field of ocean colour remote sensing. Simon worked successively for the Department of Fisheries and Oceans (DFO) Canada at Maurice Lamontagne Institute, the European Space Agency (ESA-ESRIN) and ACRI-ST between 2001 and 2003. During that time, he was actively involved in MERIS commissioning phase after the launch of ENVISAT in 2002. Dr Bélanger obtained his PhD in 2006 from Université Pierre et Marie Curie (Paris VI) at the Laboratoire d’Océanographie de Villefranche (LOV), France. His research interests are broad, from atmospheric correction and bio-optical algorithms improvement to applications of remote sensing to ocean biogeochemistry in cold Arctic and sub-Arctic environments. Simon founded Arctus in 2009 to fill a gap in the EO industry in Canada, where aquatic remote sensing expertise was not well represented. Simon’s motivation is driven by the desire to offer a stimulating R&D and peaceful environment to highly quality personal (HQPs) that want to establish in Rimouski, outside big cities and in proximity to Nature.

Robert Duplain, ing.

Chief Financial Officer

Arctus Chief Financial Officer, is a professional engineer who has developed extensive skills over 25 years of practical experience in engineering, R&D, project management and as consultant in the field of technological development. He worked at Bombardier Research Center and was member of the management team for Canadian Frigate construction Project at a major canadian shipyard. Robert joined KPMG in 1994 and developed a practice to assist clients in structuring and presenting R&D projects to facilitate financing. He collaborated with ACRI-ST for the ESA project Earth Watch.

Yanqun Pan, Ph.D.

Spécialiste en IA et couleur de l’eau

He conducted postdoctoral research at UQAR from September 2018 to September 2020, following the completion of his doctoral degree in Geographic Information Sciences from East China Normal University in Shanghai, China in 2018. In October 2020, he joined the Arctus team as an EO specialist. With a strong background in radiative transfer modeling, algorithm development, and software development, Dr. Pan has developed algorithms and processors for the application of satellite multispectral imagery and airborne hyperspectral imagery to aquatic environment. While working at Arctus, he developed a new algorithm for atmospheric correction including adjacency effects correction of Landsat-8 and Sentinel-2 images over inland and coastal waters (the new GAAC processor). Additionally, he has begun working on SDB and has developed the AI4SDB toolbox, a collection of Python procedures that combine AI and physics-based algorithms to predict optical shallow water and retrieve bathymetry from multispectral imagery, specifically Landsat OLI and Sentinel-2 MSI.

Thomas Jaegler, MSc.

Spécialiste en OT

He has joined our team to support activities as part of Sentinel-3 Mission Performance Center (S3-MPC) (ESA contract). His research interests involve optical remote sensing, in-water bio-optical and radiometric measurements. Thomas has extended knowledge in processing, analyzing and displaying spatial dataset for environmental applications using Open Source tools like R, GRASS, Python, GDAL etc. He is currently working on implementing a processing chain for the validation of Level 2 marine product of OLCI (Ocean Land Color Imager) sensor onboard Sentinel 3 satellite. He has collaborated on a review on the detection of Vibrio non-cholerae in the Canadian coastal water in February 2017. He has collaborated with Hatfield Consultant on the development of a chlorophyll-retrieval algorithm for the monitoring of Northern lake in Canada together as part of the Looknorth-funded. He has also participated at the feasibility study on monitoring environmental variables during the construction of Port of Montreal new infrastructure.

Carlos Araújo, MSc.

Spécialiste en OT

Oceanographer and joined Arctus in 2022 as an Earth Observation scientist. With more than 15 years of experience, he has knowledge in coastal geomorphological and sedimentological processes, operational and biological oceanography, geomatics, physical limnology and remote sensing. In his current PhD project, he studies the biogeochemical background that modulates the underwater optical environment in nearshore zones of the Estuary and Gulf of the St. Lawrence River, focusing on phytoplankton assemblages but also attempting to document the spatial variability of seagrass meadows over the last decades.

Simon Hurens

Analyste de données géospatiales

Simon started at Arctus in 2023 as an intern and then as a geospatial data analyst. He first studied the foundations of computer science and mathematics at the University of Montreal, after which he explored data science and the fascinating world of deep learning to apply techniques from both fields to challenges in the realm of natural sciences.


We have collaborations with various researchers at the national and international levels in academic institutions (UQAR/ISMER, Université Laval, UCC) and members of Arcticnet, research institute (NIVA), governmental departement (Fisheries and Oceans Canada, DFO) and the private sector.

ACRI-ST, an independent SME that is based in Sophia-Antipolis, France. ACRI-ST began operations in 1989 and is a major partner of Arctus. The company is deeply involved in the European Space Agency (ESA) and other Space Agencies’ Earth Observation Programs that use satellite-based sensors to monitor and detect changes in the atmosphere and on the surface of the earth (both hydrosphere and terrestrial).
