Interannual Variability of Sea Surface Height over the Black Sea: Relation to Climatic Patterns Kara, A. Birol; Barron, Charlie N.; Wallcraft, Alan J.; Oguz, Temel (American Meteorological Society, 2008-01-01) Sea surface height (SSH) variability is presented over the Black Sea during 1993-2005. The 1/4 degrees x 1/4 degrees resolution daily SSH fields are formed using optimal interpolation of available altimeter data. SSH variability reveals distinct maxima in the eastern and western basins, reflecting variations in the corresponding gyres. A joint examination of SSH and sea surface temperature (SST) indicates strong relationship between the two only in winter, with correlations as high as 0.6 or more. This woul...
Interannual variability of the early summer coccolithophore blooms in the Black Sea: impacts of climatic factors Cokacar, T; Oguz, T; Kubilay, N (2003-08-06) Interannual variability of the early summer (May-June) coccolithophore blooms within surface waters of the Black Sea was studied by means of satellite-based bio-optical observations. The performance of two coccolithophore detection algorithms were tested for Black Sea conditions, and were found to provide comparable spatial patterns consistent with the corresponding true color images. An analysis of six, year-long OCTS and SeaWiFS imagery from 1997 onwards points to the presence of a major phytoplankton blo...
Interannual and regional variability of ecosystem dynamics in the BlackSea Fach, Bettina A; Cannaby, H.; Dorofeyev, Vl; Kubryakov, Aı; Salihoğlu, Barış; Korotaev, Gk; Oğuz, Temel; Kıdeyş, Ahmet Erkan (null; 2013-01-01) A three-dimensional hydrodynamic ecosystem model developed for the Black Sea was used to investigate theinﬂuence of anthropogenic drivers on marine ecosystem functioning in the Black Sea with a special focus onregional differences. Data from the ECMWF 40 Year Re-analysis global atmospheric circulation model (ERA-40)were used to force a coupled hydrodynamic ecosystem model (BIMS) for a hindcast simulation from 1980-2000.Model skill was assessed by model comparisons with SeaWiFS surface chlorophyll distributi...
INTERINDIVIDUAL VARIABILITY OF COUMARIN 7-HYDROXYLATION IN A TURKISH POPULATION ISCAN, M; ROSTAMI, H; ISCAN, M; Güray, Nülüfer Tülün; PELKONEN, O; RAUTIO, A (1994-11-01) One hundred healthy Turkish Volunteers (70 male, 30 female) aged from 19 to 56 years were given 5 mg coumarin p.o. after an overnight fast. Urine samples were collected before and 2, 4 and 8 h after drug administration. The extent and rate of formation of 7-OH-coumarin (7OHC) was determined by the urinary excretion of the metabolite as measured with the fluorometric method.
Inter and intra annual variation in body condition of the Black Sea anchovy, Engraulis encrasicolus ponticus-Potential causes and consequences Gücü, Ali Cemal; Bascinar, Nimet Selda; Dagtekin, Murat; Atilgan, Elvan; Erbay, Murat; Akpinar, Ilkay Ozcan; Kutlu, Sebahattin (2018-09-01) Variations in the relative condition (Kn) of the Black Sea anchovy (Engraulis encrasicolus ponticus) have been evaluated over eleven overwintering seasons (2005-2016). During the study period, a linear decrease was observed in the condition each year. Difference in condition from the onset to end of winter varied between 10% and 20%. Overall however, condition displayed an increasing trend within the time frame studied. Considering the worsening state of the stock during the same period, this increasing tre...
