Discrete water samples for the determination of phytoplankton abundance and community composition were collected with a monthly frequency at 0.5, 5, 10 and 15 meters in the Gulf of Trieste – time series station (station C1). The site is part of the LTER-North Adriatic site. Samples were fixed with Ca(HCO3)2-buffered formaldehyde (0.8% final concentration) and cell abundance and species composition of phytoplankton were estimated according to Utermöhl’s method (1958), using an inverted microscope equipped with phase contrast, at 320-400x final magnifications. The overall aim of Long Term Ecosystem Research in the coastal area of the Gulf of Trieste, in the northernmost part of the Adriatic Sea and of the Mediterranean basin is to gain a better understanding of the temporal dynamics of phytoplankton bloom evolution, with particular focus on the response to natural and man – induced environmental changes.

ClimaNevada is a database that compiles climate data around Sierra Nevada mountain range (southern Spain). The aim of this database is the harmonization, standardization, documentation and integration of existing climatic data in this mountain region.

Vertical profiles of underwater photosynthetic active radiation (PAR) are collected on a monthly basis in the Gulf of Trieste – time series station (station C1). The site is part of the LTER-North Adriatic site.Data are used to characterize the light field and light extinction in the coastal Long Term Ecosystem Research station of the Gulf of Trieste, in the northernmost part of the Adriatic Sea and of the Mediterranean basin.

Secchi depth is measured on a monthly basis in the Gulf of Trieste – time series station (station C1) as a general measure of seawater transparency.General information can be found at: http://nettuno.ogs.trieste.it/ilter/BIO/index.html

The dataset is providing the information (Surface and %)on the Corine Land Cover classes available on the Braila Island LTSER.

Vertical profiles of Dissolved Oxygen are collected on a monthly basis in the Gulf of Trieste – time series station (station C1), using a multiparametric probe. The site is part of the LTER-North Adriatic site. General information can be found at: http://nettuno.ogs.trieste.it/ilter/BIO/index.html

Vertical profiles of salinty are collected on a monthly basis in the Gulf of Trieste – time series station (station C1), using a CTD multiparametric probe. The site is part of the LTER-North Adriatic site. Data are used to characterize the temporal dynamic of hydrological properties in the coastal Long Term Ecosystem Research station of the Gulf of Trieste, in the northernmost part of the Adriatic Sea and of the Mediterranean basin. General information can be found at: http://nettuno.ogs.trieste.it/ilter/BIO/index.html

Vertical profiles of pH are collected on a monthly basis in the Gulf of Trieste – time series station (station C1), using a multiparametric probe. The site is part of the LTER-North Adriatic site.General information can be found at: http://nettuno.ogs.trieste.it/ilter/BIO/index.html

Discrete water samples for nitrate (N-NO) analysis were collected at 0.5, 5, 10 and 15 meters in the Gulf of Trieste – time series station (station C1). The site is part of the LTER-North Adriatic site. Nitrite is measured colorimetrically after sample pre-filtration, using a segmented flow analyzer. Data are used to study biogeochemical nutrient cycles in the coastal Long Term Ecosystem Research station of the Gulf of Trieste, in the northernmost part of the Adriatic Sea and of the Mediterranean basin. Availability and partition of nitrogen in dissolved and particulate pools result from the concurrence of different forcing factors such as the general circulation, alternation between summer stratification and winter mixing, weather conditions, river discharge, diffuse and point-source continental inputs, sediment–water interactions and several biological processes.
