Quantifying exposure and residence time of migrating Atlantic salmon post-smolts at aquaculture sites in a region of extreme tides

Aquaculture production now exceeds capture fisheries, but concerns persist regarding environmental impacts. Salmon farms within Atlantic salmon (Salmo salar) migratory corridors may create hotspots of predation, parasites, or disease that could affect out-migrating post-smolts. H...

Deformation, metamorphism, and time: a multi-method approach to mid-low temperature geochronology in Precambrian cratons

Abstract This study examines the microstructural, petrological, and geochemical processes that disrupt date relationships within biotite and apatite. We combine SEM-EBSD, cold/SEM-cathodoluminescence, EPMA and LA-ICP-MS geochemical mapping, with in situ multi-system geochronology...

Complex interactions among invasive fishes and flow barriers combine to maintain an endangered native species

Abstract The Breede River in the Western Cape Province is one of South Africa’s major freshwater systems and of high ecological and socio-economic value. Similar to other freshwater systems worldwide, it is threatened by environmental degradation and multiple invasive species. Un...

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...
