Abstract The present study examines sources of the interannual variability in salinity on Newfoundland continental shelf observed a 40‐year time series from an oceanographic station known as Station 27. Specifically, we investigate, through lag‐correlation analysis, priori hypotheses that anomalies at 27 are determined by freshwater runoff Hudson and Ungava bays ice‐melt Bay Labrador Shelf. Interannual variations summer into were significantly negatively correlated with Shelf lag (9 months)...
Abstract A 36‐year time series from an oceanographic station, Sta. 27, located off St John's, Newfoundland, has been used to derive the amplitudes and phases of annual harmonics temperature salinity at fixed depths 0 175 m. The analysis also carried out for Newfoundland Labrador Shelf, divided into about 40 areas, using monthly mean values available literature. At surface, (salinity) are 5°C (0.5–1.0) decreasing <1°C (0.1) 150 surface amplitude is generally lower (higher) in north. phase...
Abstract Many populations of Sockeye Salmon Oncorhynchus nerka in the eastern North Pacific Ocean experienced significant productivity declines that began about 1990, but there is no consensus on mechanisms responsible. To better understand survival trends, we examined 50‐year time series for two age‐classes smolts from Chilko Lake central British Columbia. Arranging both by ocean entry year and combining them, weighted a proxy model sampling variance, reduced variance original age‐1 smolt...
Abstract Time series of temperature, salinity and ice area from the Newfoundland Labrador Shelves during 1951–86 are examined to determine temporal spatial scales variability outside annual band. Significant interannual (periods 1.8–18 a) temperature (root‐mean‐square amplitude ≈ 0.5°C) (≈ 0.1) is found at all depths and, for greater than about 100 m, exceeded or matched only by component. Vertical low‐frequency depth range 0–75 m estimated be twice as large (60 m) (30 m); whereas, 75–175...
Despite substantial research and conservation efforts, many salmon populations are in decline. Globally, is not delivering effective decision support products to help managers apply insights as informed management actions. Data Mobilization (DM) a key step towards building the wider evidence base required deliver accountable, reliable, usable scientific advice managers. Best practices for DM being adopted throughout community but have permeated deeply into culture of conservation. To address...

Given that salmon ecologists wish to improve the resilience of unmitigated anthropic climate change, a paradigm shift is required: from monitoring, passive conservation, optimal harvesting, and enhancement (spawning channels hatcheries) predicting how will respond habitat ecosystem changes exceed range historical observations.To be useful, new prediction ability must translated into effective actions.The mobilization this knowledge lead fisheries managers being better informed able react...
We need a basin-wide planning and multiple-objectives optimization tool to manage the risks inherent in relicensing complex network of hydroelectric facilities increase probability successful outcome. The goal is find best-suited most cost-effective locations for enhancing environmental recreation benefits watershed while containing costs, reducing risk generation losses, preserving existing hydro assets. Public involvement stakeholders critical under Federal Energy Regulatory Commission...
