On the observability of turbulent transport rates by Argo: supporting evidence from an inversion experiment by Ferreira, D., Forget, Gael, Liang, Xinfeng

“…Here, it is shown that extended observation of the broad-scale hydrography by Argo provides a path to improved estimates of regional turbulent transport rates. …”

Quantifying the Consequences of the Ill-Defined Nature of Neutral Surfaces by Klocker, Andreas, McDougall, Trevor J.

“…Additionally, the authors show how seasonal (rather than spatial) changes in the ocean’s hydrography can generate a similar vertical advection process. …”

ECCO version 4: an integrated framework for non-linear inverse modeling and global ocean state estimation by Ponte, R. M., Wunsch, Carl, Forget, Gael, Campin, Jean-Michel, Heimbach, Patrick, Hill, Christopher N.

“…In particular, the inverse estimate of parameterized physics was instrumental in improving the fit to the observed hydrography, and becomes an integral part of the ocean model setup available for general use. …”

Putting It All Together: Adding Value to the Global Ocean and Climate Observing Systems With Complete Self-Consistent Ocean State and Parameter Estimates by Heimbach, Patrick, Fukumori, Ichiro, Hill, Christopher N., Ponte, Rui M., Stammer, Detlef, Wunsch, Carl, Campin, Jean-Michel, Cornuelle, Bruce, Fenty, Ian, Forget, Gaël, Köhl, Armin, Mazloff, Matthew, Menemenlis, Dimitris, Nguyen, An T., Piecuch, Christopher, Trossman, David, Verdy, Ariane, Wang, Ou, Zhang, Hong

“…New observations include measurements from Argo floats, marine mammal-based hydrography, satellite retrievals of ocean bottom pressure and sea surface salinity, as well as ice-tethered profiled data in polar regions. …”

Measurements of Sea Surface Height Variability in the Eastern South Atlantic from Pressure Sensor-Equipped Inverted Echo Sounders: Baroclinic and Barotropic by Baker-Yeboah, Sheekela, Watts, D. Randolph, Byrne, Deirdre A.

“…The baroclinic contribution is geopotential height (reference 4500 dbar), which can be determined from the measured vertical acoustic travel time together with a lookup curve based on the regional hydrography. The main error source is scatter about this curve that depends on the extent to which water masses advecting along each geopotential streamline may derive from different ocean regions. …”
