The answer is that it comes from a magma source lying underneath the new island. As the magma source is depleted (sort of like a balloon deflating), the ocean floor above it subsides. Thus, the water displaced by the formation of the new island fills in the subsiding ocean floor, and so there is no net increase or decrease in sea level.

...Unless we want to think about that portion of the island that is now above sea level. In that case, the sea floor is subsiding more than it is being filled in by water being displaced by the new volcanic material. So actually the creation of volcanic islands causes the sea level to go down.

...Unless we want to think about how a new island is like a person sitting on a waterbed (the Earth's crust). The localized weight of the island/person causes the crust/waterbed to sag downwards under the weight, which makes some other portion of crust/waterbed to bulge upwards.

...Unless we want to take into consideration that the extra mass of rock forming the new island has increased the local gravity, which causes the more water to be drawn towards the new island (which raises the local sea level), but which also causes sea water to be sucked away from the rest of the ocean (causing the sea level to go down for the rest of the world).

It's all very complicated (and mostly irrelevant for the creation of a small volcanic island).... <LAUGH>

Maybe this video will be of interest.



This thread is drifting badly away from the topic of the Northwest Passage. Oh well, the thread is due to expire in just eleven more days. Season's Greetings to all.

and so MMGWC to have such a bs counter argument

Anyhow, here's some stuff to Google that may expand your mind a little or maybe even a lot:
  • Floods
  • Subduction
  • Interglacial sea level rise
  • Ground water depletion
  • Subsidence
  • Erosion
  • Tectonics
  • Gravity variations
reef you already know the answer the MMGWC won't listen to reason or look at facts that don't support their doctrine.

I think you meant "videos about the ill-fated 1845 Franklin Expedition". I doubt that there are any videos of it.

If it has never seen the light of day how do you know about it?

Jack, step back from your webpages and look up in the sky during the daytime.... the big bright object you won’t be able to look at emits the energy that regulates the climate along with the earth orbit and angle. It’s always been that way, even the ancients understood this.
Maybe you step into some science. Milankovitch cycles (a recent discovery) would have us in a cooling cycle. Human actvity has messed up natural cycles.

Quote:
During the initial discovery period of global climate change, the magnitude of the influence of the Sun on Earth's climate was not well understood. Since the early 1990s, however, extensive research was put into determining what role, if any, the Sun has in global warming or climate change.

A recent review paper, put together by both solar and climate scientists, details these studies: Solar Influences on Climate. Their bottom line: though the Sun may play some small role, "it is nevertheless much smaller than the estimated radiative forcing due to anthropogenic changes." That is, human activities are the primary factor in global climate change.
Global Warming -- Research Issues

BTW - The ancients also subscribed to the Ptolemaic universe.

Re: Northwest Passage - 2017

Those interested in polar voyages might enjoy following Randall Reeves, on S/V Moli. He left San Francisco this past October, with the goal of making a solo figure-eight circumnavigation of the Americas and Antarctica. His anticipated route is south from San Francisco to Cape Horn, east to South Africa, Tasmania, and back to Cape Horn. North up the Atlantic to Greenland, then west through the Northwest Passage during the northern summer of 2018, and back to San Francisco.

He currently is in the Beagle Channel, Chile/Argentina, waiting for his wife to arrive with repair parts for his autopilot and Monitor Windvane. They were both damaged in storms off the Chilean coast.

His blog is at Blog – The Figure 8 Voyage

Re: Northwest Passage - 2017

Well, since 'up' is strictly arbitrary, universally spatially speaking, to make a figure 8 I think he'd have to do it this way...
