This dataset describes the abundance of macro and meio-benthos from Tukyoyaktuk Harbour and Mason Bay, North West Territories, Canada. It contains 3037 records comprising 187 terminal taxa. The original paper describes sediment analyses and sample biomass, but they are not reported within this dataset. Meio- and macrobenthos were collected from Tuktoyaktuk Harbour and Mason Bay in March, 1985 to 1988. Macrobenthos (500 um sieve) were collected with a modified Van Veen sampler of 0.1 m2 area. Sediment for analysis of meiobenthos (64 and 212 um sieves) and macrobenthos (500 um sieve) was subsampled from each Van Veen sample using a 15 cm long poly-vinyl carbonate core of 0.0017 m2 crosssectional area. A second core sub-sample was collected for sediment texture and total organic content analyses. In 1985, seven and six Van Veen samples were collected from Tukoyakuk Harbour and Mason Bay, respectively. In each of 1986 to 1988, for each bay, four Van Veen grabs were collected from the same six stations. Samples were collected from soft bottom substrate at depth strata of 4-6, 8-10, and >15 m, with two stations assigned per depth strata. Benthos abundance (number-m") and wet biomass (gem-)data are reported.
