But
plankton blooms do cause dead zones.
Not exact matches
Despite the size of the
bloom, however, the
plankton did not take in a record - breaking amount of carbon dioxide — only about 20 % more carbon than that part of the ocean sequesters biologically each year.
The
plankton bloom was of larger proportion than what we
did in the area.
Satellite images as well as maps of chlorophyll abundance appear to show that the iron
did indeed fuel a
plankton bloom in August.
Do you get a different
plankton bloom if you exactly mimic Mother Nature than if you exactly mimic some supplier of agricultural chemicals?
Realistically,
do we know what the consequences of these
plankton blooms would actually be?
One thing we
do know is that
plankton blooms have been linked to increased cloud cover, which leads to cooling.
There
does need to be more study to identify exactly how much carbon dioxide is actually sequestered in the bottom of the ocean, but the use of iron as a fertilizer in naturally barren areas of the ocean to induce
plankton blooms is no different from what mankind has been
doing for thousands of yeas — albeit on the ocean versus on land.
Among other findings, the research
did show that no harmful environmental effects were noted in creating an artificially generated iron induced
plankton bloom, and that very large quantities of carbon dioxide are indeed sequestered from the atmosphere.
The good news is that such air capture could be less expensive and invasive than, for instance, such measures, mentioned above, as «seeding the oceans with iron to spur
plankton blooms» (which strikes me as a global ecological disaster waiting to happen if a mutation occurs or terrorists
do a genetic hack.)
I recall also seeing work on ocean sediments indicating that during the dusty - dry climates when lots of windblown dust is in the air,
plankton did not
bloom in the oceans in proportion to the added minerals.
