Phytoplankton and abiotic data from seasonal sampling in the Ionian and Adriatic Seas
- Abstract
-
This dataset includes phytoplankton data and abiotic data of the water column collected during a seasonal sampling carried out in 2000 along the Apulian coast in the Ionian and Adriatic Seas. The sampling events occurred along seven transects and at different sampling depths to investigate the distribution patterns of dominant phytoplankton taxa along the main niche axes. The phytoplankton data table includes 320 taxa with average individual body size per taxon. The abiotic data table includes key water column parameters (e.g., temperature, salinity, and nutrients) collected for each sampling event over time and at different depths.

- Abstract
-
Most critical issues currently faced by our society involve key environmental challenges. Pollution, land use and climate change, and their impacts on biodiversity and ecosystem integrity need to be urgently addressed, providing quantitative knowledge to be transformed into actionable strategies. Given the complexity of such challenges, a multi-disciplinary approach to the Earth System is deemed crucial. This approach involves combining field and laboratory measurements, analyses, experiments, data analysis, and modeling tools across the various interlinked environmental domains. Italy is actively involved in all major pan-European Environmental Research Infrastructures (RIs) and also hosts other nationally relevant RIs, all essential for providing the systematic and coherent information needed for high-level research. Given the large number and heterogeneity of these infrastructures, coordinated actions are essential to integrate and interlink them, as well as to harmonize their activities. To achieve an integrated approach to the Earth system and its changes, the 22 participating RIs agreed to jointly prepare and build the thematic network called ITINERIS. The primary objective of ITINERIS is to establish the italian integrated system of the Research Infrastructures in the environmental scientific domain, facilitating observation and study of processes in the atmosphere, marine domain, terrestrial biosphere, and geosphere. Such a broad-scale and long-term vision of environmental research, sustained by the main Italian scientists currently involved in European RIs, is truly innovative and it will support Italy in taking a leading role in European environmental research activities, designing the framework for the next decades.
- Funding
-
ITINERIS is a project funded by EU - Next Generation EU PNRR- Mission 4 “Education and Research” - Component 2: “From research to business” - Investment 3.1: “Fund for the realization of an integrated system of research and innovation infrastructures”.
Methods

Method Step
- Description
-
At each sampling station, vertical profiles of water temperature, salinity, dissolved oxygen and fluorescence were obtained with a SBE 9/11 Plus CTD. Water samples for phytoplankton and nutrient analysis were collected using a Carousel sampler equipped with 12 Niskin bottles (12 L). Water samples for phytoplankton analysis were collected at three depths, selected according to the fluorescence signal in order to collect samples from the maximum chlorophyll layer. Water samples for nutrient analysis were collected on a much narrower sampling grid, in order to obtain a clear definition of spatial patterns, if any. Sub-samples for nutrient analysis (silicate, phosphate, nitrate, nitrite, ammonia) were collected directly from the Niskin bottles, filtered through 0.7 mm GFF filters and stored at 20° C in 100 ml LDPE (Low Density Polyethylene) bottles until analysis.
Method Step
- Description
-
In the laboratory, nutrient concentrations were determined using an autoanalyzer Technicon II, according to Hansen and Grasshoff (1983). Dissolved inorganic nitrogen (DIN) was calculated as the sum of nitrate, nitrite and ammonia, and phosphate was determined as dissolved inorganic phosphorus (DIP). Sub-samples for chlorophyll a (Chla) determination were treated for phytoplankton biomass fractionation according to a protocol of serial filtration. For each sampling an aliquot was filtered directly onto 25 mm GF/F 0.45 mm Whatman filters (total Chl a concentration); another aliquot was passed through 20 mm plankton nets and then onto 0.45 mm GF/F (micro-planktonic fraction); a third aliquot was passed through 2 mm (Nuclepore) and poured onto 0.45 mm GF/F for the pico-planktonic fraction. The nano-planktonic fraction (2e20 mm) was calculated by subtracting the !2 mm fraction from the !20 mm fraction. Filters were stored in a freezer at 20° C until determination. Spectro-fluorimetric analyses of size-fractionated Chl a and phaeopigments were carried out according to Holm-Hansen et al., 1965. Filters were put in neutralised 90% v/v acetone and allowed to extract for 2 h. The extract was read, before and after acidification, with a Shimazu RF1501 spectro-fluorimeter. The instrument was checked on a daily basis against a solution of Chl a from Anacystis nidulans supplied by Sigma.
Sampling
