British territorial waters is 12 nautical miles around the Falklands, with the economic exclusive zone, which otherwise remains international waters, extending to 200 nautical miles.
They were not "poking around" the Falklands.
That map is deceiving. You need to use a globe, a polyconic or a zenith equidistant projection chart. If you do so, you will note that the great circle route (the most direct route between two points on the earth's surface) between the Tierra del Fuego and Mar del Plata passes right off (almost touches) the Falkland Islands. This is what explains the little dip where they strayed from that direct route to avoid British territorial waters. On the map provided, to figure the great circle route, you have to imagine a perfect arc of a circle that would go from Tierra del Fuego to Mar del Plata just touching the closest point of the Falkland Islands.
The other deceiving aspect of the chart is that if you use the proper projection chart, you will see that the boat never strays from being over the continental shelf, even if they do get close to its edge North of the Falklands. But they never get over "deep" ocean as the BBC map would seem to indicate.
