“…Freshwater input from the largest Italian and Mediterranean river, the Po, regulates the general distribution of nutrients (Degobbis et al 1986, Degobbis and Gilmartin 1990, Franco and Michelato 1992, Raicich 1996, Zavatarelli et al 1998, Socal et al 2008, productivity (Chiaudani et al 1980, Smodlaka 1986, Giordani et al 1997, and circulation (Gač ić et al 2001). There are two distinct water masses influencing the northeastern Adriatic area, viz., the less saline northern Adriatic water and the higher saline Eastern Adriatic Current (EAC).…”

Phytoplankton abundance and seasonality in the northeastern Adriatic Sea were directly related to the annual regime of the Po River discharge in the period , there was a shift in the timing of the annual Po River maximum discharge and of phytoplankton maxima from spring to autumn. In addition, the eastern coastal area was greatly influenced by oligotrophic karstic rivers and the Eastern Adriatic Current. Dominant phytoplankton taxa were defined on the basis of abundance and frequency of appearance. Such an approach may help in the comparison of phytoplankton communities within different environments. The dominant taxa were the diatoms Cerataulina pelagica, Chaetoceros socialis, Chaetoceros vixvisibilis and Pseudo-nitzschia spp., which appeared at maximum abundances )10 6 cells l -1 in more than 20% of samples. Among other phytoplankton, the most common was the coccolithophorid Emiliania huxleyi (maximum abundance of 2=10 5 cells l -1 in 50% of samples), and the dinoflagellate Prorocentrum minimum (maximum abundance of 3=10 5 cells l -1 in 12% of samples). The present state of the phytoplankton community may provide valuable information for evaluation of possible future environmental changes in the shallow Mediterranean ecosystem.

“…The shallow sea is characterised by eutrophic waters (Franco, 1982;Price et al, 1993;Giordani et al, 1997), a comparatively reduced wave activity, and a tidal range of about 1 m. The most frequent waves (Calderoni, 1982) originate from SE (Scirocco wind) and the strongest storm waves are generated by NE winds (Bora winter wind). The longshore marine currents flow southward, in the western portion of an anticlockwise circulation cell (Dal Cin, 1983;Nelson, 1970).…”

Northern Adriatic phytoplankton response to short Po River discharge pulses during summer stratified conditions

et al. 2013

View full text Add to dashboard Cite

A 275‐km‐long transversel Northern Adriatic profile from the mouth of the Po River (Italian Adriatic coast) to the Kvarner region (Croatian coastal island area) was investigated in three successive case studies in August 2008, 2009 and 2010. The short Po River pulses in August result in the surface advection of riverine water, nutrients and phytoplankton from the western to the eastern side of the Adriatic. This surface spreading exhibits inter‐annual variability depending on the riverine discharge in the preceding period. The Po River discharge pulse in August 2010 in particular resulted in an extraordinary tongue‐like advection of riverine water, nutrients, and phytoplankton towards the Eastern Adriatic coast. The phenomenon was detected using both satellite imagery and classical oceanographic measurements. In the advective water, toxic dinoflagellates were most abundant in August 2010, when the influence of the Po was greatest.
