More than one month ago, before my long break from the blog, one of you asked me how would be possible to have access to my contributions to the THORand ICES/PICES Conference for Early Career Scientist. Oceansof Change Conference contributions. I have been trying to find the way to show that information here, but it’s not an easy task. Thus, what I have done is to create a public folder in dropbox where I will share with you everything that I can make public without problems (it means no violating copyright and things like that). There, you already have both contributions. If you press in the links above, you shouldn’t have problems to get them, but in case you have…please leave a comment!
Now, let me tell you more slowly the reasons of my excitement because I try to say too many things at the same time, and in this way it’s impossible you can understand anything. And for that end, nothing better than to pass you the link to an old post published on April last year: ‘From the Surface for a Deeper Understanding’. Just in case you are lazy to read it completely again, summarizing I told you there that due to the ocean is the main heat reservoir of the Earth’s climate system (which includes the Atmosphere, Lithosphere (http://en.wikipedia.org/wiki/Lithosphere), Hydrosphere (oceans, rivers, lakes, etc.), Cryosphere (part of the Earth frozen) and Biosphere), the increasing radiative forcing (here equivalent to say heat) in the atmosphere -mainly caused by the growing concentration of greenhouse gases- was expected to be reflected as a global ocean warming. However, in the last decade the upper ocean heat storage has decelerated, which has resulted in an active search for the missing heat in the deep ocean (Fig. 1). All of that brought up for me two questions relating my PhD work concerning the ocean-atmosphere interaction and mixed layer depth variability and my work nowadays at AWI studying the changes in the deep water masses of the Arctic. The first of these questions was: what is the mechanism able to transfer so efficiently the heat from the atmosphere to the deep ocean in contrast to past observations? Until the last decade, the heat was accumulated in the upper layers. And the second, which is the contribution of the deep Arctic Ocean waters to the World Ocean heat content since their changes have hardly studied yet?
Fig. 1. Where does the energy go? (A) Estimated rates of change of global energy. The curves are heavily smoothed and somewhat simplified. From 1992 to 2003, the decadal ocean heat content changes (blue), along with the contributions from melting glaciers, ice sheets, and sea ice and small contributions from land and atmosphere warming, suggest a total warming (red) for the planet of 0.6 ± 0.2 W/m2 (95% error bars). After 2000, observations from the top of the atmosphere (black, referenced to the 2000 values) increasingly diverge from the observed total warming (red).
