Fish Stew

A reader sent me a link from a 1993 article that shows how woefully ignorant we once were when it came to underwater volcanoes. 

I actually featured this article in Not by Fire but by Ice. Here is an excerpt from Chapter 10, “Fish Stew.”

Chapter 10
Fish Stew

Underwater volcanoes affect our lives and our weather in ways we don’t understand. But how can we understand, when we don’t know how many there are? How can we understand, when we keep finding new ones by the thousands?

Marine geophysicists aboard the research vessel Melville recently discovered 1,133 previously unmapped underwater volcanoes about 600 miles northwest of Easter Island. (Easter Island is about 2,300 miles west of Chile in the South Pacific.)

And they’re huge. Some of the newly-found volcanoes rise almost a mile and a half above the seafloor. Even then, their peaks remain about a mile and a half below the water’s surface. Consisting of both seamounts and volcanic cones, they’re packed into an area of 55,000 square miles, about the size of New York state.

Scientists were shocked. “We thought we would find a few dozen new volcanoes,” said Ken Macdonald at the University of California, Santa Barbara. “Instead we found over 1,000 that had never been mapped before.” It’s the greatest concentration of geologically active volcanoes on earth. (New York Times, 14 Feb 1993, link below)

We have no idea how many volcanoes may be lurking beneath the seas. Oceanographers previously believed there were about 10,000. But now? It’s up for grabs. Only five percent of the ocean floor has ever been mapped in detail, said Macdonald.

What we do know, is that underwater volcanoes pump awesome amounts of heat into the seas.

End excerpt.

That was in 1993. Today, scientists estimate that there are more than three million underwater volcanoes.

And we wonder what is heating our seas?

  1. proper ongoing research keeps surprising itself:-)
    and should never ever be set in stone “concencus” stultified
    recently they found that not just our bone marrow is the source of new blood red cells
    our LUNGS!!!!! also make red cells
    pretty amazing and new news;-)
    turns a whole pile of treatment options right on its head
    especially the accepted practice of chemo killing bone marrow cells to cure luekemias for example.

  2. Venus supposedly has a “runaway” Greenhouse effect according to “experts”.

    “The ground shows evidence of extensive volcanism, and the sulfur in the atmosphere may indicate that there have been some recent eruptions.”

    I say that Venus’ atmosphere is due to extensive volcanism which sustains Venus’s high surface pressures and temperatures – any other explanation is simply ridiculous.

    Any water on Venus is now found in the huge volumes of sulphuric acid – H2SO4 – in the atmosphere.

    Supposedly sulphuric acid is “restricted” to a layer of clouds yet sulphuric acid has a molar mass of more than double that of CO2.

    As usual for greenhouse acolytes this doubling of weight is irrelevant !

    Heavier gases do not sink to the ground level in greenhouse effect “physics” – they remain aloft directing their radiation back to the ground while all the lighter gases sit below them !

    Yeah – right !

    “Much of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km (62 mi) across.”

    Despite the evidence for the volcanic nature of Venus’ atmospheric constitution, pressure and temperature it is supposedly controlled by a runaway greenhouse effect where by NO radiation from the Sun reaches ground level through its deep thick atmosphere.

    Just how a “greenhouse effect” – the amplification of the surface heating effect of the Sun’s radiation by the atmospheric back radiation – occurs when ZERO energy from the Sun makes it directly to the surface is best explained by there is a 97% consensus that the science is settled – in other words it is bullshit or magic !

    At 50 km above the ground Venus atmospheric pressure is equal to sea level pressure on Earth and Venus reflects most of the Sun’s energy thus appearing as one of the brightest objects in the sky.

    Just how an input of 132 W/m2 – according to the ridiculous “physics” of greenhouse acolytes- NONE of which ever reaches the ground surface sustains a standing radiation of ~15,500 W/m2 at the surface is best explained by magic rather than ever conceding that volcanic venting of hot gaseous material is much more likely responsible !

    Greenhouse acolytes can never concede that because they believe in the magical and mystical greenhouse effect !

    Venus apparently isn’t subject to the same atmospheric stripping by the solar wind that “robbed” Mars of its atmosphere despite being half the distance from the Sun and having no magnetic field.

    Why did Mars’ atmosphere disappear while Venus’ hasn’t despite Venus being so much closer to the potent Solar wind and mass ejections and similarly unprotected by a magnetic field ????

    Most likely because the Venus atmosphere is being continually renewed by hot volcanic gases which explain the temperature and pressure.

    A ‘runaway greenhouse effect” ?

    I believe in magic, fairies at the bottom of the garden etc. etc. as well !

  3. Carl Sagan wrote the following in Cosmos:
    There is an additional factor that can alter the landscape and the climate of Earth: intelligent life, able to make major environmental changes. Like Venus, the Earth also has a greenhouse effect due to its carbon dioxide and water vapour. The global temperature of the Earth would be below the freezing point of water if not for the greenhouse effect. It keeps the oceans liquid and life possible. A little greenhouse is a good thing. Like Venus, the Earth also has about 90 atmospheres of carbon dioxide; but it resides in the crust as limestone and other carbonates, not in the atmosphere. If the Earth were moved only a little closer to the Sun, the temperature would increase slightly. This would drive some of the CO2 out of the surface rocks, generating a stronger greenhouse effect, which would in turn incrementally heat the surface further. A hotter surface would vaporize still more carbonates into CO2, and there would be the possibility of a runaway greenhouse effect to very high temperatures. This is just what we think happened in the early history of Venus, because of Venus’ proximity to the Sun. The surface environment of Venus is a warning: something disastrous can happen to a planet rather like our own.

    It is this statement which has laid the basis for the CO2 alarmist view point, and at the same time provided the taxation opportunity for governments for more free money from the wages of those that have to work to live.

    At the time Carl was not aware of the thousands of NEO and NVO in the inner solar system, or the number of cometary bodies which orbit the sun, and disappear for ever.
    In fact, his statement is incorrect in his priority of Greenhouse gases – Earth also has a greenhouse effect due to its carbon dioxide and water vapour. He should have said Water vapour, Methane, and then Carbon dioxide. Both Methane and CO2 are minuscule in compression.
    Nor has he allowed for the most obvious reason for the massive pressure difference between the atmospheres of Venus and the Earth. It is my opinion that Venus has collected a major cometary impact possibly a broken up comet similar to the Shoemaker Levy impact on Jupiter.
    Possibly, on the same timescales, as the impact which ended the Clovis in North America.
