Benthic microalgal production in the Arctic: Applied methods and status of the current database.
Udgivelsesdato: Dec 2009 The current database on benthic microalgal production in Arctic waters comprises 10 peer-reviewed and three unpublished studies.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 an...
