I would be really discouraged by that much of a bloom!..I am thinking
about how our blooms grow in response to nutrients. Will pulling it
off the sea make it go away? Seems to me the answer is negative.

New algae will form as long as there are nutrients.

They can hope to pull it off faster than it can form. That is a move
ponders know.

Will blocking an area keep algae out of it? Drifting clumps, yes.
Growing clumps, no.

The Chinese bloom seem thick, so pulling them off will help. It will
be interesting seeing how the race works out. The present thick algae
is clearly too thick for the boats. Maybe they can pull it and keep
pulling enough to have the events.
