Abstract:

The present paper presents a survey of the water-filled Ojamo limestone quarry, located in southern Finland and abandoned c. 40 years ago. In order to estimate the biogeological state of the quarry, the geological and hydrographic properties were measured, and phytoplankton and zoobenthos sampling was carried out by SCUBA diving.

Ojamo can be considered to be mesotrophic. The zoobenthos was lacking bivalves and insects. The Ojamo water body had good oxygen values owing to its connection to the groundwater.
