The Cretaceous Superchron, Beaufort Isochrons, and the Motion of North America

In the last post we explored a very peculiar set of seafloor isochrons in the Beaufort Sea and Arctic ocean. We found that a perpendicular shift in seafloor spreading defined the Cretaceous Normal Superchron, the longest known period in earth … Continue reading

Idosyncratic Isochrons, and the Cretaceous Normal Superchron

The magnetic lineations in the ocean floor were first discovered using magnetometers designed for submarine detection. These isochrons are tenets of our notion of plate tectonics, yet many isochron patterns are inexplicable by our current tectonic model. We have previously … Continue reading

History on Ice

, This graphic of Greenland ice core temperature based on data by Alley has been making the rounds. I took a notion to plot human history against it and don’t know who to credit for the base graphic, but grateful acknowledge it as not … Continue reading

The Ocean Ate It

One of the arguments one hears often these days to explain the lack of lower atmospheric warming for a human generation is that the ocean is somehow absorbing the “heat” or enthalpy that Carbon dioxide is supposed to be creating … Continue reading

Aftershocks Implicate Unusual Fault System in American Canyon Quake

California can be thought of as a ice flow where multiple independent blocks with different inherent buoyancies are at times pressed together, pulled apart, and slid past each other. The M 6.1 American Canyon quake did not take place on … Continue reading

The Pacific Triangle, The Pacific doughboy, and the wave

Folks just don’t seem to have their arms around the disarray in the earth sciences these days. Climate science and plate theory are going to have to be rebuilt from the ground up, or more appropriately from the core-mantle boundary. … Continue reading
