Mediated principally by the sinking of organic rich particles from the upper ocean, the Biological Carbon Pump (BCP) is a significant component of the global carbon cycle. It transfers roughly 11 Gt C yr(-1) into the ocean's interior and maintains atmospheric carbon dioxide at significantly lower levels than would be the case if it did not exist. More specifically, export by the BCP in the North Atlantic is similar to 0.55-1.94 Gt C yr(-1). A rich set of observations suggests that a complex set of processes drives this export. However, significant uncertainties exist regarding the BCP in the North Atlantic, including both the magnitude of the downward flux and the ecological, chemical and physical processes by which it is sustained and controlled. Our lack of detailed mechanistic understanding has also hindered modelling attempts to quantify and predict changes to the BCP. In this paper, we assess current knowledge concerning the BCP in the North Atlantic in order to identify priorities for future research, as well as suggesting how they might be addressed.

MODELING THE IMPACT OF FISH AND FISHERIES ON MARINE BIOGEOCHEMISTRY: A CASE STUDY IN THE SARGASSO SEA
Dişa, Deniz; Salihoğlu, Barış; Akoğlu, Ekin; Department of Oceanography (2016-9-23)
The ocean has a crucial role in global carbon cycle. Marine ecosystems are responsible for storing the carbon within the ocean body by means of uptaking atmospheric carbon into the ocean, transforming it into organic carbon through photosynthesis and transporting to the profound depths of the ocean. Playing a significant role in the marine food webs, grazing on plankton and providing nutrient to ecosystem by its metabolic activities, fish is thought to have a considerable impact on carbon export. For this r...
The influence of nutrient loading, climate and water depth on nitrogen and phosphorus loss in shallow lakes: a pan-European mesocosm experiment
Coppens, Jan; Hejzlar, Josef; Sorf, Michal; Jeppesen, Erik; Erdogan, Aeyda; Scharfenberger, Ulrike; Mahdy, Aldoushy; Noges, Peeter; Tuvikene, Arvo; Baho, Didier L.; Trigal, Cristina; Papastergiadou, Eva; Stefanidis, Kostas; Olsen, Saara; Beklioğlu, Meryem (2016-09-01)
Losses of phosphorus (P) and nitrogen (N) have important influences on in-lake concentrations and nutrient loading to downstream ecosystems. We performed a series of mesocosm experiments along a latitudinal gradient from Sweden to Greece to investigate the factors influencing N and P loss under different climatic conditions. In six countries, a standardised mesocosm experiment with two water depths and two nutrient levels was conducted concurrently between May and November 2011. Our results showed external ...
Modeling the current and future ranges of Turkish pine (Pinus Brutia) and oriental beech (Fagus Orientalis) in Turkey in the face of climate change
Yalçın, Semra; Bilgin, Cemal Can; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2012)
Climate change is widely recognized to have potential impacts on global biotic and abiotic systems. One of the major impacts is expected on species distributions. Species distribution models (SDMs) are used for estimating the relationship between species occurrences at sites and environmental and/or spatial characteristics of those sites. SDMs can be used to understand possible responses of species to climate change. Despite some sources of uncertainty, projections onto future climate are useful and cost-ef...
A Global approach to the hydrogen production, carnon assimilation and nitrogen metabolism of rhodobacter capsulatus by physiological and microarray analyses
Afşar, Nilüfer; Yücel, Ayşe Meral; Department of Biology (2012)
One of the most important parameters affecting hydrogen production in photofermentation process is the type of carbon and nitrogen sources. For this reason in this research, the effect of different nitrogen sources (5mM ammonium chloride and 2mM glutamate) and acetate concentrations (40‐80mM) on metabolism of Rhodobacter capsulatus were investigated. First of all, physiological experiments were carried out to compare growth, hydrogen production and substrate utilization behaviors of R. capsulatus on differe...
The Effects of type and amount of organically modified montmorillonites on thermal degradation behavior and mechanical properties of poly(lactic acid)
Özdemir, Esra; Hacaloğlu, Jale; Tinçer, Teoman; Department of Polymer Science and Technology (2014)
Biodegradable polymers have gained considerable interest as a consequence of significant environmental friendly properties like biocompatibility and ability to synthesis from renewable resources. Even though many biodegradable polymers present comparable properties with petrochemical polymers, there are still many technical barriers like poor thermal resistance, and/or mechanical properties. To overcome these drawbacks, generally, nano-sized materials are incorporated into the continuous matrix. Therefore, ...
