This is longer version of a similar talk from IUGG in Prague. The main differences are the addition of results for 16N and more evidence for why the altimetry-transport relationship works at these latitudes.
Climate simulations predict a slowing of the AMOC in the coming years, while present day observations from boundary arrays demonstrate substantial variability on weekly- to interannual timescales. These arrays are necessarily limited to individual latitudes. How well does satellite altimetry replicate transbasin, full-depth ocean transports? Can we use satellite altimetry to extend our estimate of AMOC variability back in time (at 26N)? Do the spatial patterns of SSH variability help to broaden our view of AMOC strength beyond individual latitudes? This analysis complements in situ observational efforts to measure the MOC at multiple latitudes.
