Sažetak
The primary production (PP) supports the marine food web, and affects global biogeochemical cycles [1]. Therefore, measuring and monitoring PP is of huge importance for tracking ecosystem responses to the anthropogenic-driven climate change. PP can be measured in-situ, 14C technique being widely used [2], or it can be estimated by satellite remote sensing [1], and different models [3, 4]. Remote sensing and modeling estimate global PP at large spatial and temporal scale, but they have their own restrictions [4] and require in-situ data for algorithm validation [3]. As a result, in-situ time-series data is of significant importance for PP modeling in world oceans [3]. Continuous PP in-situ measurements using 14C technique are done since April 1962 at two stations in the Central Adriatic Sea: coastal Kaštela Bay and open sea Stončica station. Time- series data was corrected for overestimates of daily production using non-linear production model, and five decadal regimes were observed: 1962-1979 (118 mg C m-2), 1979-1997 (300 mg C m- 2), 1997-2008 (128 mg C m-2), 2008-2013 (251 mg C m-2), and the last one is ongoing since 2013 (154 mg C m-2) with a trend of PP decrease [3].Overall, models reveal global decrease of PP in Mediterranean. However, there is a trend of increase in Adriatic Sea [4], which may be due to enhanced anthropogenic nutrient input, and climate change effects. We conducted 14C in-situ PP measurements at Lastovo and Korčula Islands during the ISLAND project field experiment in June 2022 (i.e., during water layer thermal stratification). Daily integrated NPP was calculated: 185.50 mg C m-2 d-1 at station Maslovnjak (north of Lastovo Island), 190.04 mg C m-2 d-1 at station Struga (south of Lastovo Island), and 80.77 mg C m-2 d-1 at station Prižba (Korčula Island). More in-situ experiments are planned for the future in order to compare data points to satellite remote sensing data and to model algorithms for the future PP estimates in the Adriatic.
