Seasonal Changes of Phytoplankton Chlorophyll a, Primary Production and their Relation in the Continental Shelf Area of the South Eastern Black Sea

Bu çalışmada Mart-Aralık 2010 döneminde Güney Doğu Karadeniz kıyılarında birincil üretim ve klorofil-anın zamansal- alansal değişimi ve çevresel parametreler ortaya konulmuştur. Birincil üretim doğal fitoplankton topluluklarında yerinde C-14 inkübasyon deneyleriyle gerçekleştirilmiştir. Birincil üretim hızları su kolonu içerisinde 0,1-40 mg cm-3 d-1 aralığında önemli bir şekilde değişim gösterirken, daima fotik bölgenin üst tabaklarından ışık yoğunluğunun %10a kadar düştüğü bölgede ölçülmüştür. Derinliğe bağlı integre edilmiş birincil üretim değerleri kıyı istasyonunda 285-565 mg cm-2 d-1 açık istasyonda ise 126-530 mg cm-2 d-1 aralığında değişim göstermiştir (ANOVA, P>0,05). Öfotik bölgedeki ortalama klorofil-a konsantrasyonları kıyı ve açık istasyonlar için sırasıyla 0,30-3,57 µg L-1 ve 0,25-3,45 µgL-1 arasında değişim göstermiştir (ANOVA, P0,05). İntegre edilmiş birincil üretim ve klorofil-a değerleri arasındaki korelasyonlar değerlendirildiğinde kıyı istasyonu (r2= 0,98; P

Güney Doğu Karadeniz Kıta Sahanlığında Fitoplanktonik Klorofil-a ve Birincil Üretimin Mevsimsel Değişimi ve İlişkileri

We describe spatio-temporal variability of primary production (PP) and chlorophyll-a (Chl-a) concentration with environmental parameters during March-December 2010 period in the south-eastern coast of the Black Sea. PP was measured by a combination of 14C in-situ incubation experiments on natural phytoplankton assemblages. Primary production rates, varied notably within water column with 0.1-40 mg cm-3 d-1, were always determined in the upper part of the euphotic zone down to the 10% of light intensity depth. The depth-integrated production rates ranged from 285 to 565 mg cm-2 d-1 for the coastal station and from 126 to 530 mg cm-2 d-1 for the offshore station (ANOVA, P>0.05). The average Chl-a concentrations within the euphotic zone ranged from 0.30 to 3.57 µg L-1 for the coastal station and from 0.25 to 3.45 µg L-1 for the offshore station (ANOVA, P<0.01), whereas the levels of depth-integrated Chl-a concentrations in the offshore station (9-80 mg m-2) were greater than in the coastal station (10 to 68 mg m-2) (ANOVA, P>0.05). The correlation between integrated PP and Chl-a values for the coastal station (r2= 0.98; P<0.01) was better than for the offshore station (r2= 0.12; P>0.05).
