Oceanographic Data Collection Methods

The video discusses various techniques for improving spatial resolution in oceanography, including the use of satellites, moorings, and Argo floats. Satellites provide broad spatial coverage but have limitations in depth and detail. Moorings offer detailed temporal data at fixed locations. Argo floats, self-profiling robots, measure ocean properties globally, aiding in understanding climate change impacts. Despite advancements, challenges in comprehensive ocean observation remain.

What is one of the main advantages of using satellites for oceanographic studies?

• They offer nearly continuous global coverage.

• They provide detailed information about ocean depth.

• They can measure the salinity of the ocean.

• They are unaffected by atmospheric conditions.

What is a limitation of satellites in oceanographic research?

• They are unable to transmit data in real-time.

• They cannot provide any data about the ocean surface.

• They only offer detailed information about small areas.

• They do not provide information about what lies beneath the ocean surface.

How do moorings differ from satellites in terms of data collection?

• Moorings are more expensive than satellites.

• Moorings can only be used in shallow waters.

• Moorings offer detailed temporal data at specific locations.

• Moorings provide broad spatial coverage.

What is the primary function of the Bermuda test bed mooring?

• To track ocean currents.

• To provide global ocean coverage.

• To measure atmospheric conditions.

• To collect continuous time series data below the ocean surface.

What is an Argo float?

• A ship-mounted sensor for spatial resolution.

• A self-profiling robot that measures ocean properties.

• A type of satellite used for oceanographic studies.

• A fixed buoy used to measure atmospheric conditions.

How do Argo floats control their buoyancy?

• By using a motor to pump oil in and out of a bladder.

• By using external weights.

• By adjusting their weight.

• By changing their shape.

What is the significance of Argo floats in climate change studies?

• They provide data on ocean currents.

• They measure atmospheric temperatures.

• They offer insights into ocean warming due to climate change.

• They track the movement of marine life.

What is a challenge faced by satellites in collecting oceanographic data?

• They can only operate during the day.

• They are limited by atmospheric conditions like clouds.

• They require constant maintenance.

• They cannot measure ocean salinity.

How do satellites achieve global ocean coverage?

• By remaining stationary over one location.

• By deploying underwater robots.

• By orbiting the Earth and collecting data in swaths.

• By using a network of ground-based sensors.

What improvement has been made in satellite data collection over time?

• Satellites can now measure ocean depth.

• Satellites provide real-time data without any delay.

• Satellites can now operate underwater.

• Satellites have improved resolution for finer details.
