A WEEK IN TEMPERATURE

Lake Ontario,
in motion.

Seven days of changing water, from Toronto to Brockville. Follow the currents. Watch the temperature shift.

READING THE WATER

Colour = water temperature

The scale stays fixed for the whole week. Endpoint colours include temperatures beyond the labelled limits.

Temperature gives the trails their colour.

Current velocity drives their movement. The film interpolates between hourly NOAA lake model fields, so both the flow and the temperature change as the clock advances.

Seven model hours pass each second. The final second is a labelled replay transition back to the opening.

KINGSTON–BROCKVILLE · ESTIMATES

River currents come from a simplified, fixed, depth-averaged calculation. Estimated river temperatures follow hourly lake inflow through that field, with no heat exchange.

These river calculations are unvalidated. Enhanced river trail motion improves visibility.

BEHIND THE FILM

Scientific data,
drawn into motion.

This project brings together hourly source ingestion, interpolation on NOAA’s native triangular lake mesh, and a deterministic Canvas particle renderer. Its custom river experiments are documented separately from the government lake model data.

The result is a dated visual study of modelled conditions. Source manifests, rendering code and checks are available alongside the film.
