Ocean Observation Network MCQ - Practice Questions with Answers

Solve 2 Ocean Observation Network questions for RAS/RPSC preparation.

Practice questions

Q1Consider the following statements about the recent expansion of India's ocean observation network: 1. The government installed 15 additional tide gauges and 14 co-located satellite-navigation receivers. 2. The directional wave-rider buoy off Mauritius was deployed to monitor zooplankton biomass in the equatorial Indian Ocean. Which of the statements given above is/are correct?

A 1 only

B 2 only

C Both 1 and 2

D Neither 1 nor 2

Explanation

Option D is correct because both statements are incorrect. The government installed 14 additional tide gauges and 15 co-located satellite-navigation receivers. The buoy off Mauritius supports forecasts of Southern Ocean waves affecting northern Indian coastal waters; the 19 subsurface moorings monitor ocean currents and zooplankton biomass.

Q2How many additional tide gauges were installed under the recent expansion of the national ocean observation network?

A 7 tide gauges

B 10 tide gauges

C 14 tide gauges

D 15 tide gauges

Explanation

Option C is correct. The recent expansion included 14 additional tide gauges and 15 co-located Global Navigation Satellite System receivers to improve tsunami monitoring and coastal observation.
