Ice Core

Part 1:

Question:
What is the relationship between temperature, carbon dioxide, and methane observed from the Byrd Ice Core?
Datasets:
Byrd – Methane, del180, and CO2 Data

Part 2:
Primary Source: Antarctic and Greenland Synchronization Data for the Last Glacial Period
Authors: Blunier, T., J. Chappellaz, B. Stauffer
Abstract: This data set consists of isotopic, carbon dioxide (CO2), and methane
(CH4) data collected from the Byrd and Vostok ice cores (Antarctica) and the Greenland Ice Core Project (GRIP). Data from the Antarctic ice cores are synchronized to the Greenland GRIP records. Data measurements consist of GRIP depth, age, oxygen isotope (d18O) and CH4 data; Byrd and Vostok depth, age, oxygen isotope (d18O), CO2, and CH4 data. The data spans the time period from 10-50 kybp.

1a) Where is your proxy record from (give approximate lat/lon)?

Location: 80.0167°S, 119.5167°W Depth: 2164 M Drilled: 1968

1b) Locate it on google earth or another map.

2a) What is your proxy? Byrd Station Ice Core

2b) What climate parameter does it record?

Mean CO2 Temp CH4

2c) What can it show and what can’t it show? It can show CO2 It can’t show snow accumulation

2d) Are you comparing 2 proxy records? no

2e) Or is one a climate paramerter?

3a) What is the resolution of your record?

3b: You might consider addressing one of the following: What dating techniques are used? Are there counted annual layers? Do you know the exact accumulation rate or sedimentation rate (i.e. do you have age versus depth information?) If not, can you estimate a range of accumulation rates common for the type of record you have?

4a) What types of connections to the global climate can you speculate your proxy represents?

4b) How representative do you think your proxy is of regional and global climate? (It is possible that you don’t see a clear global
