Leighton Rolley, a systems technician on the “world’s most advanced research ship” the RRS James Cook, used a remotely operated vehicle capable to 5000 m depth to plant the Welsh dragon flag in the waters of the Galapagos, in the Eastern Tropical Pacific, according to BBC News. The shipboard team unfurled the biodegradable Welsh flag at 3500m.
The ceremony was not specifically part of the mission, apparently. Cardiff University researchers were on board conducting marine seismic work (using air guns) and collecting rock samples using the ISIS rock drill. The RSS James Cook website hosts videos of the flag planting and the seismics.
So far, the story is reported with no real thought or mention of the implications for the politics of this kind of thing. I wonder, did they have to get a permit to plant their flag at the bottom ocean? The Russians tried this recently in the Northwest Passage and got busted for “shenangians”. I’m a little curious how this plays out.
