Looking forward to reading your paper, Ice.  |

the quantity of Fe depleted through fishing is material. The biomass to Fe ratio is extraordinary numbers as high as 75,0000 to one are believed to be possible.
Fishing is a very real perturbation of the process just as farming stops without fertilizer largely.
Will look for papers. I would argue for a replacement program to complement the fishing induced depletion.
some years ago a major dust storm in Australia deposited the iron rich dust into the Tasman sea. An unguarded scientist published that it had removed several years of CO2 from a number of coal fired power stations. We in NZ are the lucky recipients of this process.

As most plants evolved with CO2 levels up to 10 times higher than present day and the Earth didn't boil but instead fecundity increased; I see no benefit in sequestration of CO2. |

In reality it is my goal to see more fish to catch and if in the process of restoring the oceans I can virtue signal I'm there.
A boat is a mile better than a Tesla. Keep kicking that dust up.

That's what I have been doing mostly full time for the past 20 years, trying to ensure more fish to catch. Would love it if you came up with something on the Fe ocean cycle. |

Looking forward to reading your paper, Ice. Actually writers cramp is getting better worked on the project some in the past week. Have renewed direction and feeling good about it. |

NOAAgate: how ‘ocean acidification’ could turn out to be the biggest con since Michael Mann’s Hockey Stickby James Delingpole23 Dec 2014 The ocean has never acidified. pH values moving towards 7.0 are said to be "neutralizing." Ocean pH values are probably becoming more alkaline due to normal geological activity. There is no bleach involved in coral expulsion of algae. The Great Coral Reef is thriving. What, exactly, is there to discuss? |

For every one of those lovely GBR pictures, there are likely thousands that show devastation/bleaching/damage. Everyone knows the the reef is dying because we hear it repeatedly, especially from Australia's public broadcasters - ABC and SBS - as well as from many newspapers. I have been hearing of the demise of the reef since I was teenager, over sixty years ago. Apparently, it's still alive, thriving, growing today.

Australia has to walk a fine line between the lucrative industry of GBR Doom & Gloom ... and broadcasting the thriving health and beauty of the GBR for tourism purposes. _______________ This picture is solely for GBR tousism porpoises.  |

If the records are to be believed, corals have survived for millions of years through coolings, warmings, high sea levels, low sea levels, higher CO2, lower CO2 ... add what you will ... and they are still with us. I see no reason to believe that they won't survive us. The parts of the GBR that I saw in 2000 appeared to be very healthy. When I was in Jeddah in the late 1990s, the Red Sea reefs seemed very healthy, diverse and extensive ... in waters that are consistently warmer and more saline than GBR waters. No bleaching that I observed.
In comparison, shallow Caribbean reefs that were very healthy in the 1980s when I first started traveling there, were dead and dying of various diseases by the 1990s. USGS research linked the introduction of some of these pathogens to African dust clouds coming off the Sahara. I don't know if this line has been followed up on.

I would suggest rubbish. The greening that is seen in the Sahara will reduce dust.
