Danger danger!!

We have successfully identified a HAB (harmful algal bloom)! We found hundreds of Dinophysis acuta  in our plankton net haul! We then did precise counts from the different depths sampled and found that the levels of Dinophysis are well above the level that can be dangerous for shellfish!

So many Dinophysis acuta (the grenade ones)! Much danger!
Also look at that lovely big Coscinodiscus (the big round one) - isn't it
We quickly found out if any oysters have been farmed locally over the last week (or if there are plans to harvest them soon) so that they can be checked for DSP and people don't eat them if they could make them ill.
