What Southern Ocean/Antarctic observations does the NRI community need?

Hi everyone

I’m involved with a Australia’s planning for some upcoming national and international Antarctic and Southern Ocean observation efforts, some focussed on the East Antarctic sector and some, like Antarctica Insync (2027) and International Polar Year (2032). There will be some modelling efforts attached to most for these, but what I’m really interested in here is canvassing the modelling community to see what observations you all really need.

This is somewhat similar to a previous topic, but this request is open to any modelling ‘realm’: atmosphere, ocean, ice sheet/shelf and BGC.

You can be platform-agnostic (in fact I’d prefer that), just let us know what variables you need and why. That could include sustained monitoring of core variables (eg. Temperature and Salinity), it could include specific high value locations; it could be e.g. a poorly-constrained parameter that is best addressed through a field campaign (if so, what time of year…).

Do try and be targeted; a lengthy wishlist is unlikely to gain much traction, but it’ll be really powerful if we can highlight just one or two things that could really make a difference. [oceanographers/ice shelf people, don’t worry, bathymetry is front and centre !]

This is an opportunity to really influence voyage/fieldwork planning, and I’m really hoping to get some great feedback.

If you’re interested in knowing a bit more about Antarctica Insync, there’s a regularly updated webpage, and if you’d like to be more actively involved consider joining the modelling Working Group here

My vote is for:

  1. Widespread coverage of bathymetry, temperature and salinity on the continental shelf. More spatial coverage at low precision (eg floats) is better for model validation / input than less spatial coverage at high precision (eg CTD).
  2. Moorings in ice shelf cavities.
