Benthic microalgal production in the Arctic: Applied methods and status of the current database
The current database on benthic microalgal production in Arctic waters comprises 10 peer-reviewed and three unpublished studies. Here, we compile and discuss these datasets, along with the applied measurement approaches used. The latter is essential for robust comparative analysis and to clarify the...

The current database on benthic microalgal production in Arctic waters comprises 10 peer-reviewed and three unpublished studies.
