A standardized permafrost ground temperature collection for Canada 2025

Abstract. Ground temperature is an essential variable for monitoring the thermal state of permafrost, developing models, and conducting fundamental research. However, the usability of GT data in Canada is often hampered by inconsistent file formats, a lack of metadata standardiza...

Uncovering the role of biogeography, resources, food web composition and time during microbial primary succession

Ecological succession is shaped by multiple processes that operate simultaneously across spatial and temporal scales. While classical succession theory generally focuses on a single trophic level within a single location, often in plants or other macroscopic organisms, recent eff...

Food well-being matters: measurement, drivers, and inequality in sustainable food choices

Purpose To better understand the conception of food well-being (FWB) conception from a consumer perspective by providing a new measurement instrument and exploring its antecedents in Canada. Design/methodology/approach To validate the FWB measure and test the structural model of...

A Coupled Experimental–Numerical Framework to Characterize Ice Fracture Mechanics for Vibration-Based De-Icing

Resonant-vibration de-icing offers a low-power alternative to electrothermal systems, but its effectiveness depends on ice fracture and ice–substrate interfacial failure under dynamic loading. This study develops a coupled experimental–numerical methodology to characterize ice fr...

Climate mitigation contributes more to population persistence than evolutionary adaptation in a long-lived seabird

Evolutionary rescue–the process by which adaptive evolution prevents population extinction following environmental deterioration –is frequently proposed as a buffer against biodiversity loss under climate change, yet its capacity to alter future population trajectories is rarely...

Shipping noise may trigger valve closure responses in exploited scallop beds of the Gulf of St. Lawrence

Shipping noise is a pervasive form of underwater noise pollution, yet its effects on benthic invertebrates remain poorly integrated into spatial risk assessments. The Atlantic sea scallop (Placopecten magellanicus), a benthic bivalve supporting the world's largest wild pectinid f...

Developing a coastal hazard prediction system in ice-infested waters – Part 1: High-resolution regional wave modeling in the Estuary and Gulf of St. Lawrence

Abstract. This study is the first of a two-part paper that summarizes the development of a prototype coastal hazard prediction system providing short-term (+48 h) forecasts of the total water level (TWL) at 50 m resolution for the province of Quebec, Eastern Canada. In this first...

Winter sediment resuspension in a submarine canyon drives the offshore export of toxigenic Alexandrium catenella cysts

Abstract Harmful algal blooms (HABs) caused by the toxigenic dinoflagellate Alexandrium catenella recur regularly in the Lower St. Lawrence Estuary (LSLE, eastern Canada). Using quantitative polymerase chain reaction (qPCR) to detect A. catenella DNA as a proxy for cyst abundance...

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Multi-omics effect of contaminants exposure during embryogenesis on metamorphosis of blue mussel Mytilus edulis submitted to maritime traffic noise

Anthropogenic underwater noise is now considered one of the ‘emerging threats and ongoing challenges to biodiversity conservation’. Physiological changes have been observed in sessile invertebrates such as bivalves. Bivalve mollusks are of particular interest because of their sen...
