A long-term (1965--2015) ecological marine database from the LTER-Italy Northern Adriatic Sea site: plankton and oceanographic observations

The present paper describes a database containing observations for 21 parameters of abiotic, phytoplankton, and zooplankton data collected in the northern Adriatic Sea region (Italy) from 1965 to 2015. Due to the long temporal coverage, the majority of parameters changed collection and analysis method over time. These variations are reported in the database and detailed in the paper.
