Puget Sound: Drifter Tracks

The map plot shows tracks from simulated surface drifter tracks over three days from the most recent LiveOcean daily forecast.

Puget Sound Drifter Tracks

The map plot shows tracks from simulated surface drifter tracks over three days from the most recent LiveOcean daily forecast. At the start time you can see the initial drifter release locations as blue dots. Using the "Time Slider" you can see where each particle goes in time. Use the playback buttons to play the forecast at different speeds.

Selecting a single drifter

If you click on a drifter, a green line will appear showing its path over the length of the forecast. Use this feature to determine the origin and destination of any single drifter.

Selecting and tracking groups of drifters

If you click on the map (not a single drifter), all the drifters within a certain distance will turn red. Increase or decrease the area of selection by zooming in or out of the map. By selecting different groups of particles at different times you can explore questions such as: Where do all the particles from one place go? or Where did all the particles that ended up in some place come from?

South Puget Sound Surface Salinity Drifters: Willapa & Grays

The movie has a panel at the bottom that shows time. The tide is evident in the twice-a-day variation of the sea surface height. Daytimes are shown as the thick yellow lines on the horizontal axis. Winds are shown by an arrow in the middle of the map, with the scale given by the circle. The black line off the coast on the map is the 200 m depth line, which marks the "shelf break" separating the coastal region from the deeper ocean beyond.
