Specifications Table

Subject	Environmental Science (General)
Specific subject area	Long-term database of physical, chemical and biological water properties of a hyper-eutrophic micro-estuary and the adjacent coastal water
Type of data	Tables
How data were acquired	1.Sampling campaigns for CTD, chemical and biological properties.
	2.Laboratory analysis of surface and bottom water for water chemistry and biology
	3.Continuous sensor sampling for temperature, salinity, oxygen and water level.
	Detailed protocols are provided in the website protocols section
Data format	Raw and plots
Parameters for data collection	Data are intended to provide a good temporal and special coverage of biogeochemical parameters in the estuary.
Description of data collection	The data are divided into three separate databases and data collection campaigns.
	A.Stationary sensors Data.
	B.Monthly surveys of water physical and biogeochemical properties along the estuary.
	C.Bi-weekly surveys of water physical and biogeochemical properties at marine stations facing the estuary mouth B and C Data are available as an Ocean Data View (ODV) ready table that is updated on a monthly basis (http://reco.ruppin.ac.il/eng/template/?Pid=26).
