    Abstract: A one‐dimensional, vertically resolved, physical‐biogeochemical model is used to provide a unified representation of the dynamically coupled oxic‐suboxic‐anoxic system for the interior Black Sea. The model relates the annual cycle of plankton production in the form of a series of successive phytoplankton, mesozooplankton, and higher consumer blooms to organic matter generation and to the remineralization‐ammonification‐nitrification‐denitrification chain of the nitrogen cycle as well as to anaerobic sulfide oxidation in the suboxic‐anoxic interface zone. The simulations indicate that oxygen consumption during remineralization and nitrification, together with a lack of ventilation of subsurface waters due to the presence of strong stratification, are the two main factors limiting aerobic biogeochemical activity to the upper ∼75 m of the water column, which approximately corresponds to the level of nitrate maximum. The position of the upper boundary and thus the thickness of the suboxic layer are controlled by upper layer biological processes. The quasi‐permanent character of this layer and the stability of the suboxic‐anoxic interface within the last several decades are maintained by a constant rate of nitrate supply from the nitrate maximum zone. Nitrate is consumed to oxidize sinking particulate organic matter as well as hydrogen sulfide and ammonium transported upward from deeper levels.

    Venice and I: How a City Can Determine the Fate of a Career
    Annual Reviews ; 2017

    Abstract: Quoting the ancient Romans: Audentes Fortuna iuvat. Being in the right place at the right time is useless if you do not grasp your Fortuna and build upon it. In this article, I expound on the milestones of my multiform research career, which over more than 40 years brought me from Venice to California to MIT; from the Venice problem to highly nonlinear, coherent structures in the ocean and atmosphere; and from the mare nostrum (the Mediterranean Sea), a laboratory for global processes, to the tropical ocean-atmosphere systems and regional coupled climate models of the Maritime Continent. The climate system, with its daunting complexity, is arguably the greatest challenge for, and the future of, the entirety of the earth sciences. Finally, living in and working for Venice has been the privilege and Fortuna of my life.
