The composition of phytoplankton assemblages in April, 1998 in Galway Bay and during a summer phytoplankton bloom occurring southwest of Ireland in August, 1998, was characterized by pigments measured by high-performance liquid chromatography. Pigment data reflecting phytoplankton assemblages dominated by diatoms in Galway Bay and dinoflagellates in the southwest of Ireland were compared to phytoplankton cell counts. Significant relationships were found between the fucoxanthin concentrations and the diatom cell numbers (P < 0. 0002 r(2) 0.63) during April, and between fucoxanthin (P < 0.0001 r(2) 0.79), 19'hexanoyloxyfucoxanthin (P < 0.0001 r(2) 0.77) concentrations and Gyrodinium aureolum cell numbers during the summer bloom.

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...
Satellite-detected early summer coccolithophore blooms and their interannual variability in the Black Sea Cokacar, T; Oguz, T; Kubilay, N (Elsevier BV, 2004-08-01) Interannual variability of the prevalent early summer coccolithophore blooms within surface waters of the Black Sea was studied by means of satellite-based bio-optical observations. Two coccolith detection algorithms, tested for the Black Sea conditions, were found to provide comparable spatial coccolith patterns consistent with the corresponding true color images. Reliability of the algorithms is also supported by several sets of time-series measurements in different parts of the basin. An analysis of 6 ye...
PHYTOPLANKTON FLUORESCENCE AND DEEP CHLOROPHYLL MAXIMA IN THE NORTHEASTERN MEDITERRANEAN Yılmaz, Ayşen; EDİGER, DİLEK; BAŞTÜRK, ÖZDEN; Tuğrul, Süleyman (1994-01-01) Two expeditions in the northeastern Mediterranean by the R/V Bilim (in July 1988 and March 1989) scanned an area of about 3 x 10(5) km2 to determine, in situ, the relative fluorescence intensities of the upper layer waters. The in situ fluorescence intensities exhibited a fair correlation with the discrete chlorophyll-a concentrations when the concentrations exceeded 0.1 mug/L. Light intensities indicated that the euphotic zone had an average thickness of 100 m in the open waters. The deep chlorophyll-a max...
Long-Term (2001-2011) Temperature, Salinity and Chlorophyll-a Variations at a Southeastern Coastal Site of the Black Sea Alkan, Ali; Zengin, Bayram; Serdar, Serkan; Oguz, Temel (2013-03-01) Long-term measurements of temperature, salinity and chlorophyll-a concentration at a coastal site off Trabzon in the southeastern Black Sea document their monthly-to-interannual variabilities during 2001-2011. The data point to a general trend of warming with either negligible or absence of the Cold Intermediate Layer except for the relatively cold period of 2002-2004. The warming trend appears to be a continuation of the one started during the early 1990s. The data further documents enhanced anticyclonic t...
Air-sea exchange in the Black Sea estimated from atmospheric analysis for the period 1979-1993 Schrum, C; Staneva, J; Stanev, E; Ozsoy, E (2001-11-01) The air-sea exchange in the Black Sea is revisited in the paper on the base of data provided from the ECMWF atmospheric re-analysis for the period 1979-1993. Climatological characteristics of analysis data are compared against available climatic data, demonstrating quite a good consistency. Several drawbacks are found: too low temperatures in the easternmost part of the sea, too low dew point temperature and slight underestimation of precipitation. However, the seasonal and inter-annual oscillations are res...
