Question

a large lagoon is far below its usual water level. what tool would researchers most likely use to gather data on the amount of fresh water entering the lagoon from the incoming stream? (1 point) a swing - arm hydrometer because it will determine the salinity a stream gauging system because it will detect flow volume a conductivity meter because it will determine the exact quantity of salt a water quality strip because it will detect contamination

Explanation:

Step1: Analyze each option

• A swing - arm hydrometer is for salinity, not freshwater volume.
• A stream gauging system measures flow volume (which is what we need for freshwater entering).
• A conductivity meter is for salinity - related (not volume).
• A water quality strip is for contamination (not volume).

Since the goal is to gather data on the amount (volume) of freshwater entering, a stream gauging system is the right tool.

Answer:

B. a stream gauging system because it will detect flow volume
