Sensors on ferry to monitor water quality in Puget Sound

The video explains how ferries equipped with Doppler current sensors are used to monitor water quality in the Puget Sound Estuary. As ferries travel across Admiralty Reach, sensors send sound waves down the water column to measure the speed and direction of water flow. This data helps scientists understand the impact on algal blooms in the estuary.

What technology is used on ferries to monitor water quality in the Puget Sound Estuary?

• Radar sensors

• Doppler current sensors

• Sonar detectors

• GPS trackers

Where does the ferry travel to collect data on water flow?

• Along the Columbia River

• Across the Pacific Ocean

• Through the Strait of Juan de Fuca

• Across Admiralty Reach

How do the sensors determine the speed and direction of water flow?

• By tracking the ferry's speed

• By measuring water temperature

• By analyzing water salinity

• By timing the echo of sound waves

What environmental phenomenon do scientists study using the data from the sensors?

• Tidal waves

• Algal blooms

• Coral bleaching

• Ocean acidification

Why is it important to understand water flow in the estuary?

• To predict weather patterns

• To improve ferry navigation

• To manage fish populations

• To assess the impact on algal blooms
