DESCRIPTION:Dr. Bieito Fernández Castro\n13:15 – 14:15 – Dr. Bieito F
 ernández Castro\nMarie Curie Research Fellow\, University of Southampton
 \, UK\n\nThe role of ocean turbulence in shaping aquatic life and vice ver
 sa\n\nCentimetre-scale turbulent mixing has a vast impact on the functioni
 ng of aquatic ecosystems\, as it regulates the nutrient\, oxygen and light
  environments of primary producers and\, consequently\, the complex\, mult
 i-trophic biota that such producers support. The question of whether the r
 everse is true – that is\, whether marine organisms are capable of gener
 ating turbulence that is sufficiently vigorous to shape the ocean’s phys
 ical and chemical properties – has been hotly debated by oceanographers 
 since the 1960s. The parties remain irreconcilable today as\, on the one h
 and\, theoretical and laboratory studies indicate that dense fish aggregat
 ions should generate intense turbulent mixing\; yet\, on the other\, the o
 bservation of this mixing has to date eluded oceanographic surveys. In thi
 s talk\, I will briefly introduce my previous research efforts in disentan
 gling the sources and variability of turbulent mixing and their broad impa
 cts on aquatic ecosystems. Then\, I will tell you about a recent study in 
 which we shed new light on the “biomixing” debate\, by reporting recur
 rent evidence from direct ocean observations of strong turbulent mixing as
 sociated with fish spawning aggregations. Finally\, I will outline my main
  research lines that I plan to develop at EPFL.\n\n\n\nShort bio:\nI am an
  highly interdisciplinary observational aquatic physicist\, working in bot
 h oceanic and lacustrine environments. The goal of my research is to under
 stand how physical and biogeochemical processes interact across spatial an
 d temporal scales to shape the functioning of oceanic and freshwater ecosy
 stems and their role in the global carbon cycle and climate. Currently\, I
  am a Marie Curie Fellow at the University of Southampton. In this project
 \, I use novel biogeochemical data from autonomous Argo floats and a data-
 assimilative model to disentangle the processes controlling carbon sequest
 ration in the Southern Ocean. Previously\, I was a PhD student in Oceanogr
 aphy at the University of Vigo (Spain)\, a postdoctoral Fellow in the Mari
 ne Research Institute of the Spanish Research Council (Vigo\, Spain) and a
  Research Assistant at the Ecole Polytechnique Fédérale de Lausanne (Swi
 tzerland).\n\n\n
