Talk:Brine rejection

I'm just a first-year student, but I think there might be a critical error in this sentence: "The downwelling of denser, briny water from sea ice creation causes upwelling of deep bottom water, and helps initiate deep ocean currents, which helps to drive thermohaline circulation." Should it not be "causes DOWNWELLING of deep bottom water"? It is near the poles that deep bottom water (NADW/AABW) gets formed and flows towards the equator, by decreasing temperature and increasing salinity causing an increase in density, making the water sink. I believe this is the way it should be, but I could just be missing something very obvious..
The sentence might have been referring to Circumpolar Deep Water (CDW) which does flow above Antarctic Bottom Water (AABW) at the south pole, and does upwell I believe, and if that were the case then "deep bottom water" should be replaced with "deep water" or "Circumpolar Deep Water," as it is not referring to "Antarctic Bottom Water (AABW)". Also, I am not aware of how this Circumpolar Deep Water interacts with brine. Kaffeefilter99 (talk) 11:01, 4 May 2016 (UTC)
