HLY-05-02 Macrofauna Data. Version 1.0 ...

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...

Description
Summary: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 0.06 square meter (89-2722 individuals per square meter) and total biomass ranged from 0.2-1.6 g wet weight per 0.06 square meter (less than 0.1-26.1 g wet weight per square meter). Infauna taxon number per station was between 8 and 55. Abundance, biomass, taxon number and diversity indices of infauna declined significantly with water depth. Polychaetes, crustaceans and bivalves dominated the infaunal densities, biomass and species numbers. A total of 99 infauna taxa were identified, including at least three new species of polychaetes. This dataset is part of the Pacific Marine Arctic Regional Synthesis (PacMARS) Project. Multivariate analysis indicated that station groups "Chukchi slope," "Canada Basin abyss" and ...
