CTD Device

Real World Example

Imagine you're trying to decide if you need to wear a jacket, and you check the weather app on your phone to see the current temperature, humidity, and wind speed. Just like how you rely on your phone to gather information about the weather to make a decision, oceanographers use a CTD device to gather vital data about the ocean's conditions. The CTD measures conductivity (like humidity), temperature (like the weather app's temperature), and pressure (similar to wind speed, which can indicate the strength of atmospheric pressure) to help scientists understand the ocean's environment, much like how you use weather data to plan your day.
