Although the video clearly shows a moving v-shaped wake it does not reveal the underlying source. The witnesses certainly saw something, but what?

Single individuals of Atlantic cod and squid occur much further north than previously expected. Scientists participating in the international MOSAiC expedition with research icebreaker Polarstern have found fish and squid in deep water in the middle of the Arctic Ocean. The results from Stockholm University, the Alfred Wegener Institute and colleagues in the European Fisheries Inventory in the Central Arctic Ocean (EFICA) Consortium are published today in the scientific journal Science […]

And if you wanted to feel the texture of an object, you would sweep your fingertips over the surface.
