Seward Marine Center telemetry
Resurrection Bay experiences dynamic salinity fluctuations due to rapid seasonal glacial meltwater and severe winter storm systems. Our joint sensor network tracks daily acidification rates, providing essential baseline data for regional shellfish and Steller sea lion foraging habitats.
📊 **UAF Seward Marine Center Sensor Sync:** Data synced continuously using solar-powered sub-surface CTD (Conductivity, Temperature, Depth) telemetric mooring sensors.

🔬 **Scientific Purpose:** The PHOCAS (Physiological and Health Observations of Clean and Atypical Seals) metabolic dome system measures continuous gas exchange ratios, helping researchers calculate exact cost-of-transport curves for wild and recovering ice seals.

💡 The "Junk Food Hypothesis":
Pollock is a low-fat, nutritionally poor prey compared to lipids-dense, calorie-rich herring. When pollock dominates Steller sea lion habitats, sea lions often lose body mass even when they eat to physical capacity. This nutritional deficit is a primary driver behind the Western stock decline.
