Project Description:
This project will study levels and sources of contaminants in shellfish, seawater, and sediment from Frobisher Bay. The overall aim is to improve understanding of the various sources that might be introducing contaminants into Frobisher Bay and the extent to which these sources impact the ecosystem. We are focusing on sediments and clams because many of the contaminants that may be present accumulate in sediments and the animals that live in or near the sediment. From the sediments, we will examine the sedimentary record to identify how contaminant sources have varied over time during the last ~100 years. From the new data on contaminant levels in clams, we will obtain information useful for health authorities to better assess the safety of harvesting clams in different parts of Frobisher Bay, including areas near Iqaluit. We will try to identify the different sources of contaminants in the area; how much they contribute relative to one another now and in the past; and what levels of contaminants are ending up in benthic animals like clams. In view of the proposed development of a deep-sea port in Iqaluit, increased shipping in recent decades and ongoing wastewater discharges from the growing city of Iqaluit, the project will provide important baseline data that will be useful for assessing potential environmental risks and stressors associated with contaminant release. Contaminant levels in samples collected near Iqaluit will be compared to levels that are far from local sources. The contaminants to be measured include metals (cadmium, mercury, and lead), PCBs, microplastics, and contaminants of emerging concern (e.g., PFASs). Hired community members will collect shellfish from intertidal harvesting sites for analysis, while sediment and seawater samples will be collected by researchers at these sites as well as deeper, offshore sites. The first year’s work will focus on analyzing a suite of contaminants in clams from local harvesting sites near Iqaluit to identify whether the community is a local source of some contaminants. We will also begin to study the sedimentary records to determine timelines of inputs. In the second year, we will focus on a priority set of contaminants and expand the spatial extent of sampling to include more remote 'background sites'. We will also integrate the results from seawater, sediments and clams to improve understanding of contaminant sources and how contaminants are transported to and within Frobisher Bay. The results of the study will help to address: 1) community concerns about impacts on the marine ecosystem of waste sites in the Iqaluit area; 2) information needs of health authorities; 3) scientific gaps about levels, trends and sources of contaminants of emerging Arctic concern. This proposed project was developed in collaboration with the Frobisher Bay Coastal Environmental Baseline Program, implemented and funded by Department of Fisheries and Oceans.

Niskin Bottle 2 1 m long The Niskin Bottle will be used to sample seawater at various depths within the water column.
Castaway CTD 1 15 cm The Castaway CTD is used to measure key water quality parameters (conductivity, temperature and depth) over the entire water column (surface of the water to the seafloor). The Castaway CTD is lowered through the water column to a maximum depth of 100 m.
Seabird CTD 1 60 cm x 10 cm The Seabird CTD, similar to the castaway CTD, is used to measure key water quality parameters (conductivity, temperature and depth) over the entire water column (surface of the water to the seafloor). The Seabird CTD is lowered through the water column to a maximum depth of 500m.
Gomex Box Core 1 40 x 45 x 55 cm The Gomex box corer is used to collect sediment cores and benthic (seafloor) creatures such as shellfish. The box corer is armed so that the bottom of the box is opened and then lowered to the seafloor where, on impact, the bottom of box is triggered to close. The box corer is than retrieved, containing sediment and benthic invertebrate for analyses.
Local boat 1 unknown A local boat (likely Silver Dolphin) will be hired from Iqaluit as the primary platform for collecting samples. The details of the vessel will be determined at a later date.
Ponar Grab sampler 1 6x6' Commonly used in both fresh and salt water aquatic environments, the ponar grab sampler is used to take surface sediment from hard bottoms that include gravel, sand, consolidated clay. Similar to the box corer, the ponar is secured to a rope and lowered to the sea floor in the open position. When the ponar lands on the sea floor and the operater pulls on the rope, the ponar shuts quickly securing surface sediment and benthic invertebrate inside. The ponar is then pulled up and samples collected.

Waste and Impacts
Environmental Impacts
We expect no environmental impacts from this project. We will be staying in the city of Iqaluit and will travel each day with local hunters and boat operators. Everything we bring out with us will return with us. The 10% hydrochloric acid will be shipped (in appropriate dangerous goods packaging) back to the University of Manitoba for proper disposal.
