Licence note
HELCOM's data page says users may distribute, remix, adapt and build upon the material so long as attribution is given (CC-BY). Data policy §5.3 sets HELCOM monitoring/assessment spatial products to a CC-BY licence with HELCOM cited as the source. The AIS shipping-density metadata says HELCOM data is free for public use when HELCOM is cited. The checked HELCOM pages do not name a Creative Commons version number, so this entry does not claim CC BY 4.0 specifically.
