SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

This journal provides a forum to promote knowledge of harmful microalgae and macroalgae, including cyanobacteria, as well as monitoring, management and control of these organisms. Both original research and review papers will be considered.
Papers dealing with the following aspects of harmful microalgae and cyanobacteria in marine and fresh waters will be considered:
• The distribution, life histories and taxonomy of harmful microalgae;
• The physiology and toxicology of harmful microalgae;
• Harmful microalgal bloom ecology;
• Trophic, socio-economic, public health and aquacultural impacts of harmful microalgal bloom events;
• Occurrence, methods of detection and chemical structure of toxins in harmful microalgae, cyanobacteria, foodwebs and seafood;
• Factors controlling toxin production, biosynthesis and chemical ecology.
Note: Papers dealing with pharmacology fall outside of the scope of the journal.
All papers will be subject to peer review. Authors will receive proofs. The editors, referees, and publisher will make every effort to expedite publication, the co-operation of authors in this task is welcomed.
