Some data

Filed under: Uncategorized — ffky @ 8:30 am

I try to introduce data in this winter, when we ready to post. We establish over 150 location and retrieved data over 100 files. It is fun to see but also time consuming process…

Here is recent data from Bethel borehole! Permafrost temperature is very close to 0 degree Celsius (-0.5dC at 12m depth). Also you see colder temperature for deeper depth. This means good indication of recent warming.

Here is Kilimanjaro ground temperature by the altitude. Higher the elevation getting colder the ground. The gradient is very low (less than 0.6dC/100m), It maybe volcanic
activities (heat flow is higher than normal). As the result, permafrost is only presence at specific thermal conditions such as thicker organic layer or high pore space materials like moraine.
