Hamme says the team's preliminary analysis suggests that trying to stimulate plankton growth by adding iron to the water would have a minuscule effect on marine CO2 absorption.

Not exact matches

Scientists thought that by providing iron, a trace element required for growth, they could create large plankton blooms and draw down atmospheric carbon dioxide.

Another high - profile test — of dumping iron particles into the ocean to stimulate plankton growth — failed miserably after being disrupted by protesters.

Only when we know when and where certain nutrients are available for plankton growth we can also estimate how much carbon the plankton can bind by photosynthesis and thus remove from the atmosphere.»

Plankton forms the main food of many ocean species, and fisheries could be badly hit by the loss of these micro-organisms as a result of warmer waters, according to the paper, published this week in the British journal Nature... Other factors that influence phytoplankton growth include [iron] dust blown from the land, and variations in solar radiation.

However, current understanding suggests that, unless substantial ocean circulation changes occur, plankton growth remains roughly unchanged because it is limited mostly by environmental factors, such as nutrients and light, and not by the availability of inorganic carbon it does not contribute significantly to the ocean uptake of anthropogenic CO2.

It's caused by excess growth in the water of a colorless plankton called «psuedo - nitzchia».
