- - - - A. Warmer summers
        ∴ greater summer melt of sea ice
      - B. Weaker katabatic winds
        ∴ less space for sea ice formation
  - - - Antarctic circumpolar current
        = in between (on shelf vs open ocean)
    - - ACC right on continental shelf
  - - - Carved by relict ice streams?
      - Deep troughs allow deepwater access to shelf
      - Evidence greater Holocene ice sheet extent? Larter et al 2014
    - - Less well mapped
- - - - less seaward Ekman
      - more shelfward Ekman
- - - - from high elevation
      - downslope via gravity
