In this paper, we review the state of the art and major challenges in current efforts to incorporate biogeochemical functional groups into models that can be applied on basin-wide and global scales, with an emphasis on models that might ultimately be used to predict how biogeochernical cycles in the ocean will respond to global warming. We define the term "biogeochemical functional group" to refer to groups of organisms that mediate specific chemical reactions in the ocean. Thus, according to this definition, "functional groups" have no phylogenetic meaning-these are composed of many different species with common biogeochemical functions.


Comparison of Productivity Plankton Types and Carbon Export Mechanisms in two Different Regimes of Subtropical North Atlantic a Modeling Study
Salihoğlu, Barış (2016-02-15)
Improved structure and mechanisms of carbon export and sequestration within marine ecosystem models is vital to better understand and predict changes in the global carbon cycle. We have implemented a 1D lower trophic ecosystem model at long-term time-series stations (BATS and ESTOC) in the North Atlantic for the years 1996-2000. We have investigated the dynamics of the productivity and carbon export, and mechanisms regulating them. Our simulations agree with the previous observations that show similar produ...
The role of SAIs in promoting sustainable development: environmental auditing
Erkan, Berna; Gaygısız Lajunen, Esma; Department of Economics (2011)
This thesis is based on cross-sectional data analyses by using Ordinary Least Squares (OLS) Method in order to determine the main drivers of the environmental performance and specifically the effects of environmental audits conducted by Supreme Audit Institutions (SAIs) on sustainable development. Two general models are employed throughout the study that have the Environmental Performance Index (EPI) as dependent variable and various sub-models for different income groups are produced to observe the individ...
Expert discourse on Turkish climate policy
Üzelgün, Mehmet Ali; Rittersberger Tılıç, Helga İda; Department of Science and Technology Policy Studies (2007)
This study renders the current frame of global climate change policies as a mirror of a new era, marked by surpass of the once absolute limits to growth towards humanity’s management and optimization of natural processes of the planet. A total of 24 interviews were realized with Turkish governmental and non-governmental experts on climate change, after application of a two-staged environmental attitude and policy questionnaire. Critical discourse analysis of interviews was performed to elaborate the results...
Modeling biogeochemical dynamics in porous media: Practical considerations of pore scale variability, reaction networks, and microbial population dynamics in a sandy aquifer
King, E. L.; Tuncay, Kağan; Ortoleva, P.; Meile, C. (Elsevier BV, 2010-03-01)
Prediction of the fate and environmental impacts of groundwater contaminants requires the identification of relevant biogeochemical processes and necessitates the macroscopic representation of microbial activity occurring at the microscale. Using a well-studied sandy aquifer environment, we evaluate the importance of pore distribution on organic matter respiration in a porous medium environment by performing spatially explicit simulations of microbial metabolism at the sub-millimeter scale. Model results us...
Trophic controls in the Black Sea ecosystem (BLACK MODE)
Fach Salihoğlu, Bettina Andrea(2008-12-31)
The study proposed here aims to understanding the functioning of the Black Sea ecosystem in terms of the "trophic cascade" control and "regime shift" mechanisms using retrospective data analysis and interdisciplinary modelling approach. The main focus of the proposal is on understanding the long-term ecological changes within the pelagic interior Black Sea ecosystem during its transformation from the pre-eutrophication phase of the 1960s to the post-eutrophication phase of the 1990s. It is devoted to ...
