What is the primary driving force behind ocean currents?

  1. Wind

  2. Earth's rotation

  3. Temperature differences

  4. Density differences


Correct Option: A
Explanation:

Wind is the primary driving force behind ocean currents, as it transfers energy to the water, causing it to move.

Which of the following is NOT a type of ocean wave?

  1. Wind waves

  2. Swells

  3. Tsunamis

  4. Internal waves


Correct Option: C
Explanation:

Tsunamis are not generated by wind, but rather by sudden disturbances such as earthquakes or landslides.

What is the term used to describe the vertical movement of water in the ocean?

  1. Upwelling

  2. Downwelling

  3. Ekman transport

  4. Thermocline


Correct Option: A
Explanation:

Upwelling is the process by which cold, nutrient-rich water from the deep ocean is brought to the surface.

Which of the following is NOT a type of oceanographic model?

  1. Numerical models

  2. Analytical models

  3. Statistical models

  4. Physical models


Correct Option: D
Explanation:

Physical models are not used in oceanographic modeling, as they are typically too expensive and time-consuming to construct.

What is the main purpose of oceanographic modeling?

  1. To predict weather patterns

  2. To study ocean circulation

  3. To assess the impact of climate change

  4. To develop new fishing techniques


Correct Option: B
Explanation:

Oceanographic modeling is primarily used to study ocean circulation, including currents, waves, and tides.

Which of the following is NOT a type of oceanographic data used in modeling?

  1. Satellite imagery

  2. Buoy measurements

  3. Shipboard observations

  4. Model output


Correct Option: D
Explanation:

Model output is not a type of oceanographic data, but rather the result of running an oceanographic model.

What is the term used to describe the process of validating an oceanographic model?

  1. Calibration

  2. Verification

  3. Sensitivity analysis

  4. Optimization


Correct Option: B
Explanation:

Verification is the process of comparing model output to observations to assess the accuracy of the model.

Which of the following is NOT a type of oceanographic modeling software?

  1. ROMS

  2. HYCOM

  3. WRF

  4. FVCOM


Correct Option: C
Explanation:

WRF is a weather forecasting model, not an oceanographic modeling software.

What is the term used to describe the process of running an oceanographic model?

  1. Simulation

  2. Integration

  3. Hindcasting

  4. Forecasting


Correct Option: B
Explanation:

Integration is the process of running an oceanographic model over a period of time.

Which of the following is NOT a type of oceanographic modeling application?

  1. Climate prediction

  2. Oil spill trajectory forecasting

  3. Search and rescue operations

  4. Coastal engineering


Correct Option: C
Explanation:

Search and rescue operations are not typically conducted using oceanographic models.

What is the term used to describe the process of improving the accuracy of an oceanographic model?

  1. Calibration

  2. Verification

  3. Sensitivity analysis

  4. Optimization


Correct Option: A
Explanation:

Calibration is the process of adjusting the parameters of an oceanographic model to improve its accuracy.

Which of the following is NOT a type of oceanographic modeling boundary condition?

  1. Open boundary condition

  2. Closed boundary condition

  3. Periodic boundary condition

  4. Wall boundary condition


Correct Option: D
Explanation:

Wall boundary conditions are not typically used in oceanographic modeling.

What is the term used to describe the process of reducing the computational cost of an oceanographic model?

  1. Downscaling

  2. Upscaling

  3. Nesting

  4. Parallelization


Correct Option: A
Explanation:

Downscaling is the process of reducing the resolution of an oceanographic model to reduce its computational cost.

Which of the following is NOT a type of oceanographic modeling data assimilation technique?

  1. Optimal interpolation

  2. Variational assimilation

  3. Ensemble Kalman filter

  4. Particle filter


Correct Option: D
Explanation:

Particle filters are not typically used in oceanographic modeling data assimilation.

What is the term used to describe the process of communicating the results of oceanographic modeling to stakeholders?

  1. Visualization

  2. Communication

  3. Outreach

  4. Education


Correct Option: A
Explanation:

Visualization is the process of converting oceanographic modeling data into visual representations that can be easily understood by stakeholders.
