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.

The dataset refers to annual mean (2011) air temperature measured at 4 forest CONECOFOR LTER plots, by automatic devices

The dataset refers to annual (2011) precipitation (sum) measured at 4 forest CONECOFOR LTER plots

Vertical profiles of temperature 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.

Dataset provides ammonia concentrations measured in Lake Santo Parmense during the period 2007-2010. Water samples were collected by means of a Ruttner bottle at different depths over the whole water column at the point of maximum depth of the lake. Samples were analysed spectrophotometrically according to Koroleff (1970).

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

Vertical profiles of salinty are collected on a monthly basis in the Gulf of Trieste – time series station 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.

Dataset provides chlorophyll-a concentrations measured in Lake Santo Parmense in 1991. Water samples for chlorophyll-a analysis were collected by means of a Ruttner Bottle at different depths over the whole water column at the point of maximum depth of the lake. Samples were analysed according to Strickland & Parsons (1968).

Discrete water samples for phosphate(P-PO) analysis were collected at 0.5, 5, 10 and 15 meters in the Gulf of Trieste – time series station (station C1).

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.
