“…Wind stress and along-coast currents regulate offshore cross-shelf transport of phytoplankton-rich waters (Martinez-Lopez and Zavala-Hidalgo 2009). We recorded relatively low concentrations of nutrients, similar to those recorded in October 2000 and April 2001 (Saracino and Rubino 2006) and in the Otranto Strait (Viličić et al 1995;Socal et al 1999). TIN/PO 4 molar ratio ranged from 39 to 1,389, with an average of 330, indicating phytoplankton growth limited by phosphorus at all stations (much more at offshore stations; Fig.…”

“…Although the role of the Po River is relatively well understood, the southeastern Adriatic (Albanian) rivers have not been seriously considered to date, neither as a physical force, nor as a nutrient source. Besides studies on phytoplankton size structure , taxonomic composition, and diversity (Saracino and Rubino 2006;Vadrucci et al 2008) in the southeastern Adriatic, there is no information on fine distribution of plankton across the Albanian shelf and continental slope, where a distinct hydrographic boundary between north westerly inflowing current from the Ionian Sea and the low salinity Albanian coastal waters can be frequently detected by satellite imagery. The discharge of rivers into the Adriatic Sea, the strong northern wind (the bora), and currents participate in the formation of fronts in the northern Adriatic (Lee et al 2005) and along the Albanian shelf (Le Vourch et al 1992).…”

We present the first insight to the oceanography of the southeastern Adriatic Sea, where coastal water influenced by Albanian rivers comes into contact with the inflowing oligotrophic Eastern Adriatic Current (Ionian Surface Water and Levantine Intermediate Water). A distinct plankton distribution was observed on each side of the shelf break hydrographic boundary in May 2009, during gradual warming of the surface waters. The prochlorophytes accumulated along the nutricline above the shelf and continental slope. The phosphorus limited inshore waters were dominated by a small diatom Chaetoceros circinalis, dinoflagellates, cryptophytes, autotrophic picoplankton, and heterotrophic nanoplankton. The offshore surface layer was characterized by bigger nanoplankton (coccolithophorids, green flagellates). Low nutrient concentrations influence relatively low productivity not only above the Albanian shelf but also further to the north along the Montenegrine and Croatian coastal Adriatic Sea.

“…The NANO-dominated phytoplankton consisted mostly of phytoflagellates measuring less than 10 mm, as is generally the case throughout the Adriatic (Saracino and Rubino, 2006). Chroococoid cyanobacteria were the major NANO from May to October, reaching 2.9 x 10 7 cells L -1 in July, the period of N limitation.…”

SUMMARY: Phytoplankton and physical-chemical parameters were investigated for the first time in the only natural hyperhaline marine lakes (salinity >40) along Croatia's Adriatic coast, Mala Solina and Velika Solina. Two periods were recognized during the one-year investigation: one euhaline-mesotrophic from December to May and one hyperhalineeutrophic from June to November. Nutrient limitation appears to have been important in defining the lakes' seasonal phytoplankton composition. Phosphate was most likely limiting from October to December, silicate from January to April, and nitrogen from June to September when nitrate was depleted. Diatoms were most abundant in November to January, when temperature and salinity were low and nitrate and ammonium were high. They collapsed in March when silicate was depleted. Amphora, Navicula, and other naviculoid diatoms were the most frequent genera. Nitzschia longissima was the most abundant species. Dinoflagellate dominance began in June in Mala Solina and in March in Velika Solina. It continued while temperature, salinity, phosphate, and silicate were high. Oxyrrhis marina was the most abundant dinoflagellate (3.2 × 10 6 cells L -1 ). Nanophytoplankton was the dominant size fraction. Chroococoid cyanobacteria were most abundant from May to October, reaching 2.9 × 10 7 cells L -1 in July. Both nanophytoplankton and small microphytoplankton, such as Oxyrrhis, Scrippsiella, and Tetraselmis, were most abundant under hyperhaline, N-depleted conditions. Toxic and harmful taxa (e.g. Alexandrium, Dinophysis), expanding in Mediterranean waters, were not recorded in the lakes.Keywords: phytoplankton, hydrography, nutrients, eutrophication, marine lakes, Adriatic Sea. RESUMEN: Respuesta del fitoplancton a la limitación de nutrientes y salinidad elevada en lagunas hipersalinas en el Adriático oriental. -El fitoplancton y diversos parámetros físico-químicos fueron estudiados por primera vez en dos lagunas hiperhalinas naturales (salinidad >40) de la costa de Croacia, Mala Solina y Velika Solina. El estudio se llevó a cabo durante 1 año, y pudieron distinguirse dos períodos: uno euhalino -mesotrófico, de diciembre a mayo, y el otro hiperhalino -eutrófico, de junio a noviembre. La limitación por nutrientes resultó ser un factor determinante para las variaciones estacionales en la composición del fitoplancton de las lagunas. El fosfato fue limitante de octubre a diciembre, el silicato de enero a abril, y el nitrógeno de junio a septiembre, una vez consumido el nitrato. Las diatomeas fueron especialmente abundantes entre noviembre y enero, cuando la temperatura y la salinidad eran bajas y la concentración de nitrato y amonio eran altas. El número de diatomeas disminuyó en marzo, tras el agotamiento del silicato. Amphora, Navicula y otras diatomeas naviculares fueron el género más frecuente, y Nitzschia longissima fue la especie más abundante. La dominancia de dinoflagelados comenzó en junio en Mala Solina y en marzo en Velika Solina, y se mantuvo mientras la temperatura, la salinidad, y la...

“…For example, in the Indian Ocean, Bhat and Matondkar (2004) noted the occurrence of C. polykrikoides in the coastal waters of Goa, India, while Ramaiah et al (2005) reported blooms along the Malabar Coast of India. Large blooms of C. polykrikoides have also been recently noted in the Black Sea (Vershinin et al, 2004(Vershinin et al, , 2005Terenko, 2005), Croatian coastal waters of the Adriatic Sea (Saracino and Rubino, 2006) and in the Mediterranean across the Gulf of Olbia (coastal Italy; Sannio et al, 1997). One of the more significant HAB events of the last decade occurred throughout the Arabian Gulf and Gulf of Oman from 2008 through 2009 when a massive bloom of C. polykrikoides caused fish kills, the death of coral reefs, and disruption of desalination plants in Iran, Saudi Arabia, and the United Arab Emirates (Richlen et al, 2010).…”
