The buoys measure wind direction and speed, air temperature and humidity, and temperature of the ocean at the surface and at various depths to 500 meters below the surface. A few buoys also measure currents, rainfall, and solar radiation. Data and position are relayed by satellite to scientists around the world every day.

Researchers use the data to learn how to predict future changes in the world's climate. The buoys were first deployed to learn how to predict the El Nino/ Southern Oscillation phenomenon. El Nino events involve disruptions in the ocean surface winds and the upper ocean temperature pattern. These disruptions lead to seasonal climate variations and changes in fish migration patterns in many areas of the world ocean including the tropics.

The data are also made available to weather forecasters around the world. In the tropics, there are very few locations or ships that regularly report the weather. Measurements of the observed weather conditions that these buoys record and transmit regularly are an essential ingredient in weather predictions.

Sea surface temperature is an important tool to find many different species of fish. The buoys provide this information to weather centers daily. These centers, in turn, produce charts of sea surface temperature and distribute them via radiofax broadcasts to fishermen at sea or to your home office. Knowing where to look for fish saves both fuel and time.

Several nations have also successfully used surface wind and ocean current information from the buoys to help locate missing or overdue boats.

The ability to predict future El Nino events and to estimate the degree to which they will disturb the ocean can help fishermen plan their operations in advance.

No! Each buoy in the Array is securely anchored by steel cable and deployed with a short scope. They are under a great deal of tension and, if lifted out of the water, are dangerous to you and your crew.
