Why are satellites useful tool for measuring sea temperature?

Why are satellites useful tool for measuring sea temperature? The oceans are very large and water is always moving – this makes them hard to study! In the past, sea temperatures in the oceans could only be measured by ships and buoys. These measurements capture a single point in space and time There were big gaps between measurements Ship-based measurements are time-consuming and expensive Satellites have improved our ability to measure SST by allowing frequent and global coverage.
