Density of seawater at 15 °C
Open-ocean seawater at 35 g/kg salinity and 15 °C — 1025 kg/m³, the 64 lb/ft³ that separates salt-water from fresh-water load lines.
A single published state at 15 °C. This library carries no temperature curve for seawater, so there is one value here rather than a chart — showing a flat line across a range nobody measured would suggest a constancy the data does not claim.

Treat this as a room-temperature figure and nothing more. Every property here moves with temperature in reality; this library simply has no table for how.
