Reading @ian_urbina The Outlaw Ocean he mentions the city of lights, a (squid) fishing ground to the north of the Falklands. (Illegal) fishing vessels light up the ocean to attract / catch squid. Being stuck inside I made a first pass on a map of this in #rstats.

Still needs some annotations, but I'm calling it it a day. Fun detail, look at the continuous waters (dotted line) and how the vessels skirt this rather perfectly to the west of the Falklands.
