Temporal trends of emerging pollutant deposition through ice core sampling on the Devon Ice Cap ...
Two 15 - 20 m ice cores were collected near the summit of the Devon Ice Cap in late April - early May of 2015. Samples were shipped frozen to Environment Canada in Burlington, Ontario. Ice core dating will be done through in situ borehole 137Cs gamma spectroscopy to locate the depth of the 1963 atom...
