Profiling Accumulated PAHs and Metabolomic Responses in Truncate Soft-Shell Clam (Mya truncata) in the Canadian Arctic

This dataset included contaminant data of polycyclic aromatic hydrocarbons (PAHs) and a variety of metabolites measured in truncate softshell clams (Mya truncata) collected near Iqaluit, Canada. Clams were hand collected during extreme low tide from two locations (n = 10) in Koojesse Inlet in August 2022. Samples were collected to determine the extent of PAH contamination in the region and the possible impacts it would have on clam populations as well as local communities that rely upon this species as a locally harvested food source.

In total, 52 alkylated and non-alkylated PAHs were assessed in clam whole bodies, including the US Environmental Protection Agency’s 16 priority PAHs. 51 metabolites were assessed in both the mantle and gills, and all clams were assessed for length, width, thickness, body mass and body condition.

This study was performed as a follow-up to a previous study of clams from the same locations performed in 2019 that investigated growth, biomarker responses and accumulation of inorganic elements in response to municipal wastewater exposure:

Green Sea Urchin Biomass Assessment at the Mouth of the Saguenay Fjord in 2019

In the summer of 2019, The Agence Mamu Innu Kaikusseht (AMIK) carried out the biomass assessment of green sea urchin (Strongylocentrotus droebachiensis) at the mouth of the Saguenay Fjord. This study follows on from the green sea urchin assessment that began in 2016. The study was carried out in the sub-area 9-1 with the standardized protocol of the Maurice-Lamontagne Institute (MLI). The monitoring made it possible, among other things, to assess the state of the resource and to understand the issues related to the green sea urchin. 

For this study, each station was bounded by transects of 100 m long. On each of these transects, quadrats were placed at every 20 m. A total of 138 quadrats for 23 transects have been done. The information collected (quantity, weight, diameter, type of substrate, etc.) is presented in the given database. 

This project is part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada.

Invasive species, Driver of Environmental Change: eDrivers Project for the St. Lawrence System

The data used to characterize invasive species risk come from the global cumulative impacts assessment on habitats and are available on the [NCEAS online data repository](https://knb.ecoinformatics.org/view/doi:10.5063/F1S180FS).

Cargo volume was used as a proxy of invasion risk under the assumption that risk of invasion is proportional to tonnes of goods transferred through ports. Cargo throughput in metric tonnes for the year 2011 was accessed through a variety of sources and cross-matched with entries in the World Port Index database (WPI).

Protection and Development of the Pointe Sauvage of the Municipality of Les Bergeronnes (2004)

The bergeronnes berry sector was identified during the years 1997-1998 as an exceptional natural environment thanks to a recognition of Saint Laurent-Vision 2000. It is part of the 37 protected sites along the St. Lawrence River. The Comité ZIP de la Rive nord de l'estuaire also recognized the value of this habitat and, in 2001-2002, carried out a characterization study that included, in addition to the Bergeronnes bays, 12 other coastal habitats of interest along the Lower Estuary Saint Laurent. Pointe Sauvage was then identified as a site with a high potential for conservation and development. 

In the spring of 2004, the Comité ZIP proposed to the municipality of Bergeronnes to carry out this pre-feasibility study. The municipality then expressed a strong desire to conserve and enhance the two bays, as well as the Lac Salé and the Pointe Sauvage that they surround. In this context, the *Comité ZIP* and the *Fondation de la faune du Québec* have joined forces to carry out this study.

Influence of Vessel Disturbance on Pacific Harbour Porpoise (Phocoena phocoena vomerina) Echolocation (2016-2022)

Vessel disturbance is one of many anthropogenic threats that are negatively impacting coastal cetacean populations worldwide. Noise pollution from vessels can cause varying levels of disturbance in cetaceans, depending on several factors such as vessel type and speed. Pacific harbour porpoises (Phocoena phocoena vomerina) are distributed throughout coastal waters of the North Pacific Ocean, with large aggregations observed near the entrance to the Port of Prince Rupert in British Columbia, Canada. This area serves as an important year-round foraging ground for harbour porpoises. However, it is also one of the fastest growing container ports in North America, with planned increases in activity. Harbour porpoises are highly sensitive to vessel-related acoustic disturbances, but the effects of vessel activity on their foraging rates remain unclear. In this study, we used a combination of land-based surveys, passive acoustic monitoring (PAM) devices (C-PODs and F-PODs), and Automatic Identification System (AIS) data to investigate the relationship between vessel activity and harbour porpoise echolocation activity - both foraging and non-foraging - in the heavily trafficked Chatham Sound, adjacent to the Port. Our results show that an increase in the total number of vessels negatively affected both foraging and non-foraging echolocation activity, with less echolocation observed in the presence of more ferries and tugs. Similarly, vessels travelling at higher speeds (>12 knots) had a negative effect on echolocation activity. Tugboats and passenger vessels, in particular, had a wider range of effects on all harbour porpoise echolocation activity. Our findings indicate that implementing a vessel slowdown (~10 knots) along the approach to the Port of Prince Rupert would reduce disturbances to harbour porpoises and likely benefit other co-existing species which rely on quiet oceans for communication and foraging.

Real-Time CTD Data From the Atlantic Zone Monitoring Program (AZMP) VIKING Buoy Anchorages

CTD  'near real' time in-situ and 1 meter binned data. No quality control has been performed on this data.
Data are available in two versions :

- in situ : data at levels as recorded by the CTD ;
- binned :  data average in 1 metre bins .

Data are from the following 7 Viking buoys: PMZA-RIKI, PMZA-VAS, AZMP-ESG, AZMP-STA27, IML-7, IML-BA and NORTH-AJAX

Fisheries and Oceans Canada monitors the marine environment using automated oceanographic buoys as one of its tools, designed and developed by a scientific team from the Maurice Lamontagne Institute, in partnership with Multi-Électronique. In addition to measuring a multitude of meteorological and oceanographic parameters at the water surface, these buoys independently collect temperature and salinity profiles to a depth of 200 m without human intervention, and transmit the data in real time.

The buoys are part of the Department’s Atlantic Zone Monitoring Program’s sampling strategy, which, since 1998, has been assessing the oceanographic conditions in the Gulf of St. Lawrence, the Scotian Shelf, and the Newfoundland and Labrador Shelf. The program aims to better understand, describe and predict the state of the marine ecosystem, as well as to quantify the changes observed in the physical, chemical and biological properties of the ocean, whether they be seasonal, yearly, or over longer periods. In fact, the buoys are floating laboratories that operate 24 hours a day. They are invaluable to the scientific community for studying climate change and monitoring the state of the ocean.

The automatically acquired profiles are used to quantify the rapid temperature and salinity changes that can occur (due to tides, for example) and to put into context the biological samples obtained by scientists on board vessels at much lower frequency. Mariners also appreciate having offshore wind and wave conditions available in real time from online services.

The Portneuf-sur-Mer Salt Marsh - Characterization of Important Coastal Habitats on the North Shore of the St. Lawrence Estuary

A project to characterize important coastal habitats on the north shore of the St. Lawrence Estuary was funded for a period of 4 years (2018-2022). The purpose of this project is to generate reference ecological data to draw a global portrait of the state of coastal marshes in the upper north shore sector of Quebec.

This dataset covers the Portneuf-sur-Mer swamp sector. In order to improve knowledge of this ecosystem, floristic and faunal inventories (ichthyological and benthic) have been carried out and the various abiotic factors characterized. A project carried out in parallel by the Comité ZIP de la Rive Nord de l'Estuaire broadened the characterization of the Portneuf-sur-Mer marsh by adding a geomorphological component. A characterization report including an intervention plan was thus produced and is available in this dataset.

It is possible to consult the dataset on the geomorphology of the Portneuf-sur-Mer marsh as well as the five other marsh datasets that were characterized as part of the project to characterize important coastlines:
