12/n Yesterday I shared the very beginning of it, today, let's talk about where it was when I started my research on these as a postdoc at @mit_eaps in 2006 #sharehdr
13/n A lot was still unknown about the Eighteen Degree Water at this time: quantifying the layer and understanding its driving mechanisms were at the heart of the CLIMODE project #sharehdr
14/n Combining a exhaustive set of in situ experiments and numerical simulations was the strategy to tackle these questions in the CLIMODE project #sharehdr
15/n Collaborating with John Marshall, @GaelForget, Martha Buckley and Ivana Cerovecki , we (a) reconciled all diverging quantitative estimates of the water mass census and seasonal cycle, providing a clear picture of how the water mass is structured and evolves #sharehdr
16/n Collaborating with John Marshall, @GaelForget, Martha Buckley and Ivana Cerovecki , we (b) also mapped where the water mass is formed and ventilated every winter, providing a coherent picture between different mechanisms of water mass transformation estimates #sharehdr
17/n One has to see how the seasonal cycle and winter time harsh weather really "punshes" into the water mass, resetting oxygen, stratification over very short periods and deep depths: #sharehdr
18/n My time at @mit_eaps, was a great leap forward my understanding of the ocean, "Standing on the shoulders of giants" and "drinking from a fire hose" really makes sense #sharehdrmitadmissions.org/help/faq/drink…
6/n I'll start the defense by the very beginning of it (should I ?), and like for many oceanographic studies, it all started seriously with the 1872-1876 Challenger Expedition. en.wikipedia.org/wiki/Challenge…#sharehdr
7/n In 1873, going from St Thomas to Bermuda up to Halifax, they collected these amazing deep temperature data: between 100 and 300m depths, the ocean temperature is nearly homogeneous from station 52 to station 25, i.e. over 1000km centered near Bermuda #sharehdr
8/n This is highly remarkable because this ocean layer (highlighted in red) with nearly uniform temperature extends through a particularly large region and thickness, which is totally unusual for the upper surface layer of the ocean ! #sharehdr
1/n Dear colleagues, on Nov. 27th I will defend what we call in France a "HdR". Wikipedia says it's "a qualification required in order to conduct self-contained university teaching", en.wikipedia.org/wiki/Habilitat…#sharehdr
2/n ... adding: "The degree is conferred for a habilitation thesis […], which was reviewed by and successfully defended before an academic committee", en.wikipedia.org/wiki/Habilitat…#sharehdr
3/n This "successful" defense has not happened yet, and I'm preparing it right now, full time till Friday. I thought I could try to share with you here, key graphics and figures and thoughts during my coffee breaks ! #sharehdr
