“…The mechanisms driving this northward current are under investigation. One possible assumption is that this flow is generated by wind bursts during this time period (Batifoulier et al, 2010). On the opposite, north of 47.5°N, on the Celtic shelf, we observe an equatorward current, relatively intense (mean speed around 5 cm s −1 ) compared to the mean circulation on the shelf.…”

The objectives of this study were to determine the harmful species of dinoflagellates, to determine the concentration of nutriens in surface waters, and to analyze factors affecting the ecological aspects of the harmful dinoflagellates. The results showed that there were 7 genus of dinoflagellates found in this study i.e., Ceratium spp., Gymnodinium sp., Dinophysis sp., Gonyaulax sp., Noctiluca sp., Protoperi-dinium spp., and Peridinium sp. Protoperidinium spp. and Ceratium spp. were the predominant species, with their abundance ranged of 9-659 cells/L and 6-556 cells/L, respectively. In temporal scale, values of DO and water light penetration were not significantly different (α>0.05), while for the parameter of nutriens, salinity, and abundance were significantly different (α<0.05). Total abundance of dinoflagellates was significantly correlated with nitrate, nitrite, ammonia, phosphate, salinity, and DO. Harmful dinoflagellate species such as Dinophysis sp. (DSP), Gymnodinium spp. (NSP and PSP), Noctiluca sp. (anaerobic), and Gonyaulax sp. (anaerobic) were observed in the study area. The high concentration of ammonia (>1 mg/L) in the waters of Losari beach also indicated that the area was affected by anthropogenic activities. Minimizing nutrient inputs from the land was becoming the most priority measure to be done to avoid such effects related to dinoflagellate harmful algae bloms.Keywords: anthropogenic, dinoflagellates, harmful species, Makassar, nutrients.

“…These results suggest a coastward/northeastward "dynamic" with the persistence or recurrence of (current) forcing conditions in this direction. The northward component of this "dynamic" corresponds to the summer and autumn shelf northward current pulses (up to 50 cm/s) described by Batifoulier et al (2012Batifoulier et al ( , 2013, Le Boyer et al (2013), and Kersalé et al (2014). Neverthless, to date, no in-situ bottom-current meter records have corresponded with the eastward component of this dynamic.…”

“…These studies revealed 7-to 22-day northward alongshore current pulses reaching up to 50 cm (on average, 38 cm) two or three times per year in the summer or autumn over the entire water column. These events are related to wind forcing and/or surface cooling, which induces downslope bottom currents transporting coastal waters offshore and generating horizontal density gradients on the bottom and strong northward currents (Batifoulier et al, 2012(Batifoulier et al, , 2013Kersalé et al, 2014;Le Boyer et al, 2013).…”
