There are approximately 39794 data measurements taken from 3547 stations that are avaliable either through request or download from the LIMNADES database at the current time. Measurements stretch back nearly 30 years with most being recorded between 2000 and the current time. The hope is to further grow the database into the future and fill in any gaps.

Datasets held within LIMNADES are associated with number of different licences. A summary of licences across a selection of the more common datasets contained within LIMNADES is detailed below
|Type of measurement||Table name||Licence A||Licence B||Licence C||Licence D||Licence E|
|Apparent Optical Property (AOP)||Remote Sensing Refectance (λ) (sr-1)||45||557||377||1157|
|Biogeochemical constituent||Chlorophyll a (mg m-3)||785||242||490||10100|
|Biogeochemical constituent||Inorganic suspended matter (mg l-1)||39||508||72||7754|
|Biogeochemical constituent||Phycocyanin (mg l-1)||237||389|
|Biogeochemical constituent||Total suspended matter (mg l-1)||39||508||72||7754|
|Inherent Optical Property (IOP)||aph (λ) (m-1)||367||718|
|Inherent Optical Property (IOP)||aCDOM (λ) (m-1)||39||367||719|
|Inherent Optical Property (IOP)||aNAP (λ) (m-1)||367||500|
As you can see many of the licences held within the LIMNADES database are request only data licences (C-E), meaning that if you are interested in that data you will have to make a request to that particular data owner. A smaller percentage is however open access and free to download (A-B).
