used to collect data to predict an El Niño

The correct answer is "buoys".

Explanation:

Weather buoys are instruments used to collect data in the ocean as well as to aid to measure and repair the damage caused by accidental chemical spills. The weather data collected in the ocean is helpful to predict the climate consequences of El Niño. The US National Oceanic and Atmospheric Administration (NOAA) operate a network of buoys that measure weather variants provoked by El Niño, such as temperature, currents and the speed of the wind.
