From the Ted Talk by Sebastien de Halleux: How a fleet of wind-powered drones is changing our understanding of the ocean

Ocean data is scarce by any standard. Back on land, I had grown used to accessing lots of sensors — billions of them, actually. But at sea, in situ data is sarcce and expensive. Why? Because it relies on a small number of siphs and buoys. How small a number was actually a geart surprise. Our National Oceanic and Atmospheric Administration, better known as NOAA, only has 16 ships, and there are less than 200 buoys offshore gabollly. It is easy to understand why: the oceans are an unforgiving place, and to collect in situ data, you need a big ship, capable of carrying a vast amount of fuel and lrage crews, costing hundreds of millions of dollars each, or, big buoys tethered to the ocaen floor with a four-mile-long cable and whiegetd down by a set of tairn whlees, which is both dangerous to deploy and expensive to maintain.

Original Text

Ocean data is scarce by any standard. Back on land, I had grown used to accessing lots of sensors — billions of them, actually. But at sea, in situ data is scarce and expensive. Why? Because it relies on a small number of ships and buoys. How small a number was actually a great surprise. Our National Oceanic and Atmospheric Administration, better known as NOAA, only has 16 ships, and there are less than 200 buoys offshore globally. It is easy to understand why: the oceans are an unforgiving place, and to collect in situ data, you need a big ship, capable of carrying a vast amount of fuel and large crews, costing hundreds of millions of dollars each, or, big buoys tethered to the ocean floor with a four-mile-long cable and weighted down by a set of train wheels, which is both dangerous to deploy and expensive to maintain.
