Antractic Circumpolar Current by Felix

Felix has been contributing valuable insights pertaining to this mission in comments sections in this blog  but I think some of them deserve their own indexing below so I'll include them in their own post when I can. This latest from him deals with the ostensible ocean current around Antarctica...

felix has left a new comment on your post "Was Andhoy & his crew stopped?": 

Somewhat unrelated, but I found this nice map of the Antarctic Circumpolar Current ACC the world's "largest ocean current"

It could easlily be adapated to an outer Antarctic circle model 

Once again, NASA is very active here

Most studies of the alleged circumpolar current have taken place in the Drake Passage, unsurprisingly.

The Antarctic Circumpolar Current (ACC) as represented by the Mariano Global Surface Velocity Analysis (MGSVA). The ACC is poorly represented here because of the lack of data. The MGSVA is based on ship-drift estimates of sea surface velocities that are mostly available along major shipping routes.

hmmmm

Here's another diagram from New Zealand showing the current

Hi, I'm Captain Rick of the Virtual Circumference Voyage of Antarctica. I intend to prove definitively if Earth is flat or a sphere by paying careful attention to how many miles we cover as we travel "around" Antarctica. Flat earth theory says it's 50-60,000 miles. Spherical Earth theory says it 14,000 miles. Join me and ask any questions that you think would help our mission.
