An encounter is anywhere that a refrigerated cargo vessel meets up with a fishing vessel while at sea. Our current algorithm requires these vessels both to not be moving and almost next to each other for a few hours. We cannot know what, exactly, these vessels did during this encounter, but it in many cases they are exchanging fish, supplies, or crew. You can read more about transshipment behavior from our report or scientific publication.
