I am trying to study microalgal diversity (estuarine and marine species) of the algerian coast and I need the key to determining these species. What is the degree of impact of a river on marine life in the sea Mediterranean specifically?
I think that microalgae identification through microscope and keys is very hard without anyone experienced at hand. If you don't have anyone to help you with that until you get practice, I definitely recommend to go straight to DNA sequence. Let me know if you have questions about this.
i am not an expert at doing this but I know under the Helsinki Commission they have been doing this for a very long time for the Baltic Sea. Usually their methods are publicly available. You can even trying contacting them to ask.
