Canada Basin Ocean 1 Infauna CCGC Louis S. St. Laurent 2002-23
Entry ID: UAF_CanadaBasin

Abstract: This dataset investigates the macro- and megabenthos of the Canada Basin, which
is one of the biologically least known areas of the Arctic deep sea.
Macro-infauna was collected with 11 box cores at six stations ranging from 640
to 3,250 m water depth. Total abundance ranged from 3 to 265 individuals 0.04
square meters (756,625 individuals per square meters) and decreased with
increasing depth. ... View entire text

Quality The animals counts were done according to convention: sorting under a stereo
microscope after sieving and preservations. A 250µm mesh was used for sieving.
Accuracy is unknown. Box cores likely lose some light epifauna during coring
process, but this is the most common deep-sea infauna collection tool used.

Sieve size used: 250 µm. Thickness of sampled sediment layer: top 3 cm (mud
layer above solid clay). Box core area: 0.25 square meters. Very small number
of samples (11 box cores) taken in entire study area (Canada Basin, Northwind
Ridge, coordinates above).
Access Constraints None
Use Constraints Do not redistribute to third parties. When not provided by taxonomist,
taxonomic information was completed using ITIS (e.g. in many cases for ORDER).
