|
Summary of Field Work: |
We propose to collect organic and inorganic carbon samples (water column & surface sediment) for analysis of natural radiocarbon signatures. |
|
Summary of Facility Requirements: |
We would need a CTD rosette with 10 L Niskin bottles and a box-corer or multi-corer |
|
Summary of other requirements and comments: |
Research vessel would need to pass radiocarbon swipe tests at RSMAS and NOSAMS |

Repeating Cruise?

Yes |

Description of Repeating cruise requirements: |
We wish to repeat sampling in late summer/early fall when the water column in the lake is stratified |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We wish to use the Blue Heron as we are sampling Lake Superior during stratified and unstratified periods. For each cruise (total of 2 in 2009) we'd like 10 science days to perform radiocarbon measurements and microbial incubations at 5 sites in the lake, plus the necessary transit days |
