(2017) Long-term benthic ecology sampling, inner Frobisher Bay, 2016. Waterloo, Canada: Canadian Cryospheric Information Network (CCIN). Unpublished Data Benthic grab samples and underwater towed video samples were collected at long-term ecology sites while onboard the Government of Nunavut vessel MV Nulialjuk and CCGS Amundsen in July and October 2016. On-board the MV Nulialjuk, benthic grab samples (triplicate samples) and underwater towed video samples were collected at 5 long-term ecology stations near Iqaluit. An additional 7 benthic grab samples (triplicate samples) and towed video samples were collected near Cairn Island. On-board the CCGS Amundsen, benthic grab samples were collected at two long-term ecology stations (triplicate samples) near Cairn Island. Sampling gear included a Van Veen grab sampler, box core, and HD GoPro video system. Initial observations suggest that these stations are predominantly muddy sand with some larger cobbles present. Towed video analysis and benthic grab samples indicate the presence of the algae Laminaria sp. and Agarum clathratum and bivalves Mya truncata, Yoldia hyperborea, Clinocardium ciliatum, and Serripes groenlandicus. Ophiuroid echinoderms and tubiculous polychaete worms and tubes are abundant. Once all benthic grab samples and towed video samples are processed, this data will be compared with the historic sample data to answer questions about the nature of long-term change of the benthos at this region in inner Frobisher Bay. Long-term data collection is required for monitoring changes to the benthos. Historical benthic sample data for inner Frobisher Bay was initially collected by the Arctic Biological Station between 1967 and 1976 (Wacasey et al. 1979, 1980) at stations near the city of Iqaluit and Cairn Island. This area provided an opportunity re-sample these historically sampled stations to assess the nature of long-term community change within benthic communities in inner Frobisher Bay. The objective of this research is to characterize benthic community change on a small and large spatial and temporal scale by comparing historically sampled data with newly collected sample data.

Benthic sample data does exist at 12 sample locations in inner Frobisher Bay, near Iqaluit and Cairn Island. These stations were sampled between 1967 and 1976. Memorial University of Newfoundland students have returned to these stations to re-sample the benthos in 2016. The purpose of this research is to compare this historical data with newly collected data to answer questions about long-term change to the benthos in this region. Research Program(s): ArcticNet.
