Tahuna benthic microalgae:
here is what happens after we leave the wee things alone for 3 days.... seems to be lots more of them
We can do better than try and count them, we can extract their chlorophyll and measure how many there are that way

What about in the water.... what can we find there....
Lets go and tow our plankton net around behind a kayak for a while, thanks boys
Monaco estuary plankton:
Mud Snail Farming investigation
If we change the number of snails in an area will this change the amount of food (algae) in the mud?
Lets find out:
Average snail density in the estuary is 77 / m2 (see previous study)
Our changed densities: 0, 2X normal and 4X normal
ie 0, 50 and 100 in a metal hoop "farm" that is 1/3 m2
Next step collecting mud samples and extracting the chlorophyll to measure the amount of algae.... done!
the pics below show how we did all this:

Maybe we are not the first to think about these things.......
