HLY-05-02 Macrofauna Data [Bluhm]
This dataset contains soft bottom metazoan infauna (larger than 250 micrometer) that was collected with 33 box cores at 11 stations ranging from 817 m to 3961 m water depth in the high Arctic Canada Basin from 28 June to 25 July 2005. Total infauna abundance ranged from 0.6 to 50 individuals per 0.0...
