Changes in the hydrologic aspects of climate are of optimum importance. However, the details of past changes in the hydrologic cycle are difficult to reconstruct. In this report we show the firs results of the analyses of paleohydrological proxies (n-alkanes) that allow the reconstruction of multiple terms of the hydrologic budget in the GPNP. We analyzed a core from Lake Trebecchi (GPNP), and after the definition of the age-dating chronology, we measured the concentrations of n-alkanes and their major indexes (ACL, Paq, C27/C31) usually selected to infer information about hydrological evolution of the ecosystems.

Chlorophyll concentrations are provided from 6 depths (0 to 60 m) from the LTER- Marechiara Station in the Gulf of Naples on 4 seasons, 2012. The four data were chosen as to represent differen phases in the seasonal cycle of plankton in the Gulf of Naples

Dataset provides nitrate concentrations measured in Lake Santo Parmense in 1991. 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 by means of the Sodium Salicylate Method (Rodier, 1978).

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).

Dataset provides ammonia concentrations measured in Lake Santo Parmense between june 1973 and october 1974. 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 according to Solorzano (1969).

Dataset provides chlorophyll-a concentrations measured in Lake Santo Parmense during the period 1973-1975. 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 Lorenzen (1967).
