SoundHAB: FW: North Hood Canal bloom update

[Jan Newton]

Rita,
I played with the website a little...and got it to "work"...

If you go to Image access,
then select Group:  Coccolithophores
Age: Living
Genus Name:  %
Species Name: %
Ocean Area: all oceans

For some reason if you put "Emiliania" in the Genus and/or if you put 
"huxleyi" in the Species Name, then you don't get anything back.  But if 
you put "%" in both, which returns all, you get a long list, but you can 
scroll down and it includes 4 categories for Emiliania huxleyi.

I think it would be interesting if someone did an SEM.

best,
Jan
