Regional seas are potentially highly vulnerable to climate change, yet are the most directly societally important regions of the marine environment. The combination of widely varying conditions of mixing, forcing, geography (coastline and bathymetry) and exposure to the open-ocean makes these seas subject to a wide range of physical processes that mediates how large scale climate change impacts on these seas' ecosystems. In this paper we explore the response of five regional sea areas to potential future climate change, acting via atmospheric, oceanic and terrestrial vectors. These include the Barents Sea, Black Sea, Baltic Sea, North Sea, Celtic Seas, and are contrasted with a region of the Northeast Atlantic. Our aim is to elucidate the controlling dynamical processes and how these vary between and within these seas. We focus on primary production and consider the potential climatic impacts on: long term changes in elemental budgets, seasonal and mesoscale processes that control phytoplankton's exposure to light and nutrients, and briefly direct temperature response. We draw examples from the MEECE FP7 project and five regional model systems each using a common global Earth System Model as forcing. We consider a common analysis approach, and additional sensitivity experiments.


Determinants of temperature and salinity in the Levantine Sea using in-situ data
Serimözü, Cem; Taşıran, Ali Cevat; Sustainable Environment and Energy Systems (2019-8)
The Levantine Sea, part of the Eastern Mediterranean where international interests collide and exposed to rising anthropogenic pressure, is our focus in this study. Additionally, four of its sub-regions: Cilician and Levantine Basins, Coastal Nile Delta and Rhodes Gyre are chosen. On account of the relative scarcity of scientific studies of these regions, we aimed to contribute to the investigation of Sea Water Temperature and Salinity, two critical oceanographic parameters in the context of climate change....
Fuzzy vulnerability assessment model of coastal areas to sea level rise
Özyurt, Gülizar; Ergin, Ayşen; Department of Civil Engineering (2010)
Climate change and anticipated impacts of sea level rise such as increased coastal erosion, inundation, flooding due to storm surges and salt water intrusion to freshwater resources will affect all the countries but mostly small island countries of oceans and low-lying lands along coastlines. Turkey having 8333 km of coastline including physically, ecologically and socio-economically important low-lying deltas should also prepare for the impacts of sea level rise as well as other impacts of climate change w...
Potential Impacts of Climate Change on Turkish Water Resources: A Review
Yılmaz, Koray Kamil; Yazıcıgil, Hasan (2010-09-04)
Water resources are mainly controlled by the climate conditions. Global warming will therefore have evolving impacts on water resources and poses important challenges for sustainable development. Studies are rapidly emerging with focus on potential implications of climate change on Turkish water resources. These studies can be grouped into two major fields: (1) Studies investigating the degree of climate change reflected in the past observed hydro-meteorological records, and (2) studies investigating potent...

(2011-10-29)
The migration of Lessepsian species, which was the result of the opening of the Suez Canal in 1869 and further facilitated by human activities and environmental conditions, seems to play a key role for fisheries particularly in the Levant basin. However, there is still lack of accurate data for most of the Lessepsian species in order to evaluate their positive or negative effect to the fisheries catches and local fish stocks. The Project "Scientific and Institutional Cooperation to Support Responsible Fishe...
Changes in precipitation climatology for the Eastern Mediterranean using CORDEX RCMs, NHRCM and MRI-AGCM
Mesta, Buket; Sasaki, Hidetaka; Nakaegawa, Tosiyuki; Kentel Erdoğan, Elçin (2022-07-01)
© 2022Mediterranean Basin is expected to be one of the regions most severely impacted by global climate change. However, the complex interactions of driving forces of climate in the region create a challenge for climate projections for the future. Findings from climate change studies support the inter-model and inter-regional variability of projections on climate change impacts. On the other hand, the studies on the evaluation of the simulation skills of high-resolution climate models for the region particu...
