Book Description
This book contains articles presenting current knowledge about the formation and renewal of deep waters in the ocean. These articles were presented at an international workshop at the Naval Postgraduate School in Monterey in March 1990. It is the first book entirely devoted to the topic of deep water formation in which articles have been both selected and reviewed, and it is also the first time authors have addressed both surface and deep mixed layers. Highlighted are: past and recent observations (description and analysis), concepts and models, and modern techniques for future research. Thanks to spectacular advances realised in computing sciences over the last twenty years this volume includes a number of sophisticated numerical models. Observational as well as theoretical studies are presented and a clear distinction is established between open-ocean deep convection and shelf processes, both leading to deep- and bottom-water formation. The main subject addressed is the physical mechanism by which the deep water in the ocean can be renewed. Ventilation occurs at the surface in areas called the gills, where water is mixed and oxygenated before sinking and spreading in the abyss of the deep ocean. This phenomenon is a very active area for both experimentalists and theoreticians because of its strong implications for the understanding of the world ocean circulation and Earth climate. This major theme sheds light on specific and complex processes happening in very restricted areas still controlling three quarters of the total volume of the ocean. All articles include illustrations and a bibliography. This book will be of particular interest to physical oceanographers, earth scientists, environmentalists and climatologists.

Book Description
We have begun an inquiry into the process of open-ocean deep convection guided by the field observations collected in the western Mediterranean during the past winter. Our goals are to understand the role of planetary rotation in the sinking and spreading of cold water and test our understanding against field observations and laboratory models. Objectives were to understand and parameterize the convective scale in general circulation models and to provide a context in which to design future observing programs for open-ocean deep convection.

Book Description
"Understanding how the ocean takes up heat is crucial to improve prediction of the future global surface temperature increase. While many previous studies have evaluated the spatial distribution of heat content change across the global ocean, a complete explanation of the mechanisms responsible for this distribution remains largely unknown, and hence, we lack a measureable indicator of model performance that could help constrain future prediction. We examine a large ensemble of climate models to understand what creates the large inter-model variability in heat content change under global warming. Based on earlier studies on ocean vertical heat transfer, we hypothesize that open water deep convection is an important mechanism for the transfer of heat from the deep ocean to the atmosphere. Therefore, the cessation of convection, as predicted in future climate change scenario, would contribute to the increase of deep ocean heat content. We compare the convective volume and ocean heat content anomalies in 34 climate models of the IPCC Assessment Report 5. Most of models show signs of open water deep convection in the North Atlantic and in the Southern Ocean, and the variability in convective volume is linked to ocean heat content anomalies in individual models. In order to identify the most realistic climate models in term of these parameters, we compare the model convection against observations. While convection in some models is a robust predictor of deep ocean heat uptake, the models suggest a diversity of processes plays a role in the transfer of heat to the deep ocean." --
