Global Climate Change seminar - Records in Ice

What gets incorporated/trapped into (sampled by) glacial ice?

Process of snow to ice:

How are annual layers evident?

What is accuracy of layer counting?

What is length of record they have from Greenland?

From isotopic to temperature signatures:


Discussion questions:

What were results of analysis of Greenland cores?

What might be a particular important control for Greenland and Antarctica, and how might that be related to global climate change?

With what record can the ice sheet records be compared with in order to establish global patterns?

Small ice caps on Svalbard.

Next we will start to investigate what might be some of the consequences of global warming?

Reading for next time:

Discussion question: What drives thermohaline circulation (be as specific as possible), and list factors that determine its pattern.
