Vertical distributions of dissolved organic carbon (DOC), nitrogen (DON) and phosphorous (DOP) were studied in the Southern Adriatic basin in two contrasting periods: autumn (high stratification) and winter (high extent of mixing). These data provide the first observations of dissolved organic matter (DOM) stoichiometry in a key area of the Mediterranean Sea.


A comparative study of spectrophotometric and iodometric back titration methods for hydrogen sulfide determination in anoxic basins
Basturk, O; Romanov, A; Gokmen, S; Konovalov, S (2000-01-01)
Iodometric Back Titration (TBT) and Spectrophotometric (SPM) methods are two common methods used in the determination of hydrogen sulfide concentrations in anoxic basins, like in the upper sections of the Black Sea anoxic waters. Although the results obtained by both methods are in agreement when the concentrations of sulfide are higher than 30 mu M/l, IBT analysis gives more reproducible results compared to SPM analysis. On the other hand, the reproducibility of the SPM is better than that of IBT method wh...
A comparative study on the abundance and elemental composition of POM in three interconnected basins the Black the Marmara and the Mediterranean Seas
Çoban Yıldız, Yeşim; Tuğrul, Süleyman; Ediger, Dilek; Polat, Çolpan (2000-01-01)
The abundance and elemental composition of suspended particulate organic matter in the upper lay-ers of the interconnected Mediterranean, Marmara and Black Seas having different ecosystems weredetermined in 1990-1998. The aim was principally to compare the C:N:P ratio of seston and understandfactors controlling the seston composition in near- and off-shore waters of these seas. In the MarmaraSea, euphotic zone average particulate concentrations varied regionally and seasonally between 10-35 ìMf...
The chemical composition of Black Sea suspended particulate organic matter pyrolysis GC MS as a complementary tool to traditional oceanographic analyses
Coban Yıldız, Yesim; Chiavari, D; Fabbri, D; Yılmaz, Ayşen; Tuğrul, Süleyman (Elsevier BV, 2000-03-01)
A “traditional” description of the abundance and chemical composition of suspended particulate organic matter (POM) in open and coastal waters of the southern Black Sea in June 1996 has been confirmed and extended by pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) analyses. Py-GC/MS provided depth profiles of the relative concentrations of twenty three marker compounds characteristic of chlorophylls (CHL), lipids, carbohydrates (CBH) and proteins produced by thermal degradation of the POM retained...
Decreasing diversity of rare bacterial subcommunities relates to dissolved organic matter along permafrost thawing gradients
Zhou, Lei; Zhou, Yongqiang; Yao, Xiaolong; Cai, Jian; Liu, Xin; Tang, Xiangming; Zhang, Yunlin; Jang, Kyoung-Soon; Jeppesen, Erik (Elsevier BV, 2020-1)
Dissolved organic matter (DOM) released from permafrost thaw greatly influences the biogeochemical cycles of, among others, downstream carbon, nitrogen and phosphorus cycles; yet, knowledge of the linkages between bacterial communities with permafrost DOM heterogeneity is limited. Here, we aim at unravelling the responses of bacterial diversities and metabolic profiles to DOM quantity and composition across permafrost thawing gradients by coupling an extensive field investigation with bio-incubation experim...
Assessment of the trophic status of the Mersin bay waters, Northeastern Mediterranean
Kaptan, Mehmet Salih; Tuğrul, Süleyman; Department of Chemical Oceanography (2013)
Identifying the spatial and temporal variability of eutrophication related indicators such as Chlorophyll-a (Chl-a), oxygen saturation (DO%), dissolved inorganic nitrogen (DIN) and total phosphorus (TP), as a measure of the potential pressures and productivity, were measured within the Mersin Bay, a wide shelf region of the Cilician Basin located in the Northeastern Mediterranean Sea. This study aims to characterize the trophic status of the water masses in the eastern shelf waters of the bay fed by river d...
