I'm certain they don't mean BCE here. That kind of bad editing makes me doubt every fact in the piece. Not that they aren't necessarily true, but it makes me suspect the whole endeavor.
Edit: They've fixed that, so my complaint no longer stands.

But I find it interesting to consider that not all enterprising seafarers would have considered it a good idea for knowledge of exploitable resources across the sea to be publicized.
If we exclude prehistory, there is only a 130 years "gap" between known European activities in the "New World". Vikings/Normans came well into the 14th century and Basques (from ports close to Nor[se]-man-dy) came in the early 16th century.
If you include Cabot in the late 15th century. IMHO that looks like a rather small gap to "rediscover" things. At that point I wonder if it's harder to prove that the knowledge was fully lost or prove that it wasn't.
