Bivalve Inventory Around the Community of Pessamit (2019)

In the fall of 2019, Agence Mamu Innu Kaikusseht (AMIK) carried out the inventory of bivalves around the community of Pessamit, in the northern part of the shellfish sector N-05.1.3.1 and the sector N-05.1.3.2. The aim of this project was to estimate the shell banks by evaluating the biomass of all edible species that can be exploited by the community and to acquire knowledge about the different species. 

A total of 340 stations were sampled. For each station, the species were identified, measured, counted and weighted. Other information such as the type of sediment, grain size, etc. were also entered in the database. Depending on the station, the sampling was done either by the pumping technique with the Venturi system or by the conventional technique with the shovel. 

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

Tour of the Townships on Erosion (Magdalen Islands), 2011

During the winter of 2011, The Attention FragÎles team met with approximately 300 Islanders to discuss shoreline erosion. Meetings were held in 13 Island townships between January and March, from Havre-Aubert to Grande-Entrée, including Entry Island. The "Tour of the Townships on Erosion" project aimed to:

1) Bring the Islands’ citizens together to hold conversations and to share their knowledge about the issue and better understand the phenomenon of erosion, its impacts, and inherent risks;

2) Engage citizens in a joint examination of the human factors that either aggravate or attenuate erosion and formulate concrete action proposals that address those factors;

3) Make sure dune restoration projects last in the long term by setting up committees and mobilizing citizens to participate in the restoration work.

The idea behind the township tour was to give citizens a voice and a chance to speak about this central theme for the archipelago's future. All those wishing to understand this phenomenon, talk about it, voice their ideas, and think about the causes and the solutions together joined us in these conversations. A presentation on the following elements was given at each of the meetings:

1) the phenomenon of erosion and its natural and human causes;

2) a mapping of local issues in each township that was visited;

3) currently available solutions to fight against coastal erosion with each solution’s pros and cons.

The citizens were then invited to share their experiences and how they perceived the evolution of the coastline over the years. We talked about the citizens' role, the authorities' responsibility and their expectations, and the option of creating committees to carry out some of the work. These meetings were also summarized to the mayor and councilors of the Municipality of the Magdalen Islands.

Recruitment and Abundance of the Blue Mussel (Mytilus edulis) Along the Shore of the St. Lawrence Maritime Estuary (2003-2010)

Abundance data (biomass and density) of populations of blue mussel (Mytilus spp.) in the mid-littoral zone from 2007 to 2010. The biomass data (after drying by sponging) come from 6 quadrats (0.0225 m2) at each of 29 sites visited during the summer on the south shore of the St. Lawrence lower estuary.

Mussel recruitment data (number of recruits/collectors) on artificial Tuffy-type collectors (S.O.S. Tuffy Pad) spaced 1-100 m and exposed for 2 months (mid-July to mid-September) in the low-lying mediolittoral zone. The data represent the number of individuals per collector (8 collectors per site) associated with 29 sites in the St. Lawrence lower estuary from 2003 to 2010.

It is possible to consult the following 2 articles for more information:

Knowledge Acquisition on the Striped Bass (Morone saxatilis) Habitat in Baie des Chaleurs Area (2010)

The main aim of this study is to support the conservation and protection of the Striped Bass (*Morone saxatilis*). Field sampling made it possible to assess the presence or absence of spawning grounds, nursery areas, and breeding areas of striped bass in the Cascapedia River estuary in 2010. The inventory of eggs and larvae was initiated from mid-May to end in mid-July. It is carried out through the use of a conical plankton net. Juveniles were sampled using a shoreline. No eggs or larva of striped bass have been collected. No striped bass juveniles have been collected either.

Long-term Monitoring of Shoreline Debris in the Placentia Bay Area, Newfoundland (2018-2020)

This data was collected between 2018 and 2020 at 8 sample sites around Placentia Bay and consists of two data types: (1) Shoreline surface debris (SSD), and (2) Shoreline buried debris (SBD). With the exception of two sample sites, which were only visited once, in the first year of monitoring, frequency of sampling varied between daily, monthly or seasonally depending on the sample site, and was reduced to half-effort sampling in year 2.  


In an effort to understand the importance of shoreline substrate and environmental factors at play on rocky shorelines, sediment type, stranded seaweed (wrack) cover, and the presence of snow and ice were recorded and carefully monitored in both datasets. SSD surveys identified debris visible on the shoreline surface from standing height, down to a lower size limit of 2cm. SBD surveys employed sample quadrats to remove sediment and wrack samples from the shoreline, down to a depth of ~5cm. Marine debris down to a lower size limit of 1mm was extracted from these samples using a combination of visual separation and seawater floatation protocols. For SSD data, debris abundance, density, and source category information were recorded. For SBD data, debris abundance, density, source category, size, and colour information were recorded.

COR1503 Expedition in the Old Harry influence zone of the Gulf of St. Lawrence: marine geology data, sediment characterization

COR1503 Expedition of the Old Harry project took place from June 8th to 20th 2015 on board the research ship (R/V) Coriolis II. The general objective was to perform detailed geophysical surveys (high-resolution multibeam bathymetry and seismic profiles) and to collect different types of sediment samples, in order to evaluate the potential risks of oil and gas exploitation on the marine ecosystem of the Gulf of St. Lawrence (Old Harry Influence Area).

This dataset includes sample locations and high-resolution images of the cores (photo). Different sediment properties were analyzed:

**Physical properties**: spectrophotometry (L a b, RGB, XYZ, Munsell color), gamma density, P-wave velocity and amplitude, fractional porosity, resistivity, impedance and grain-size.

**Magnetic properties**: magnetic susceptibility.

**Chemical properties**: 14C isotopic dating.

Daily Freshwater Runoffs of the St. Lawrence at the Height of Quebec City

**METHODOLOGY**

The daily mean run off is estimated using a One-Dimensional model forced by the flows from the basins of the Great Lakes, the Ottawa River and the lateral rivers to the St. Lawrence River, and finally by the observed water level at Saint-Joseph-de-la-Rive using the Lefaivre, D’Astous et Matte (2016) method. The mean uncertainty is 1000 m3/s.

Use of the COI Marker for the Development of an Approach for Characterizing Coastal Species Using Environmental DNA (eDNA)

Species characterization by environmental DNA (eDNA) is a method that allows the use of DNA released into the environment by organisms from various sources (secretions, faeces, gametes, tissues, etc.). It is a complementary tool to standard sampling methods for the identification of biodiversity. This project provides a list of invertebrate species whose DNA has been detected in water samples collected in 2018 using the mitochondrial marker COI.

The surveys were carried out in the summer of 2018 from August 11 to 14, between Forestville and Godbout (Haute-Côte-Nord) from the vessel CCGC Leim. Sampling was carried out between 9-52 meters depth in 40 stations with one sample par station. Two liters of water were filtered through a 1.2 µm fiberglass filter. DNA extractions were performed with the DNeasy Blood and Tissue extraction kit (Qiagen). Negative field, extraction and PCR controls were added at the different stages of the protocol. Libraries at the COI locus were prepared by Genome Quebec and sequenced on an Illumina MiSeq PE250 system. The bioinformatics analysis of the sequences obtained was carried out using an in-house analysis pipeline as reported in Bourret et al. 2022. A first step made it possible to obtain a molecular operational taxonomic unit table (MOTU) using the Cutadapt software for the removal of the adapters and the DADA2 R package for the filtration, fusion, chimera removal and data compilation. The MOTUs table was subsequently corrected by taking into account the negative controls, where the number of observations in the latter was removed from the linked samples. Singleton MOTUs have also been removed. Finally, the taxonomic assignments were carried out on the MOTUs using the IDTAXA classifier (present in the DECIPHIER R package) using a training set trained on the [COI reference bank for Gulf of St. Lawrence](https://github.com/GenomicsMLI-DFO/MLI_GSL-rl) and a threshold of 40. Detections with an “Unreliable due to gaps'' category were reported at the genus level only.

The file provided includes generic activity information, including site, station name, date, marker type, assignment types used for taxa identification, and a list of taxa or species. The list of taxa has been verified by a biodiversity expert from the Maurice-Lamontagne Institute.

This project was funded by Fisheries and Oceans Canada's Coastal Environmental Baseline Program under the Oceans Protection Plan. This initiative aims to acquire baseline environmental data that contributes to the characterization of significant coastal areas and supports evidence-based assessments and management decisions to preserve marine ecosystems.

Carbonate Chemistry Along a Small River-Coastal Ocean Continuum (Kamouraska River, Qc, Canada)

This dataset contains all the chemical parameters measured during expeditions between May 2021 and October 2022 in the surface waters of Kamouraska's coastal waters. The data are divided into two databases.

The first contains all chemical parameters measured at fixed stations. Sampling was carried out along the Kamouraska River - Upper St. Lawrence Estuary coastal water continuum at 10 to 13 stations, depending on the expedition. The sampling strategy was to start collecting samples in the Kamouraska River at high-water slack water, then move towards the upper St. Lawrence estuary. Fixed stations upstream of the Kamouraska River, where the water is too low to go up with the boat, and at the mouth of the Kamouraska River, are also included in this database, along with the coordinates of all the stations. Surface water samples were collected using a Niskin bottle, and physico-chemical parameters were obtained using a CTD probe on board the boat, and using a YSI probe for the other stations.
Parameters measured include :

- Temperature - T
- pH<sub>NBS</sub>
- pH<sub>T</sub>
- Practical salinity
- Dissolved inorganic carbon - DIC
- Measured Total alkalinity - TA<sub>meas</sub>
- Calculated Total alkalinity - TA<sub>calc</sub>
- 13C signature of the DIC - δC13-DIC
- Total nitrates - ƩNO<sub>3</sub>
- Nitrites – NO<sub>2</sub><sup>-</sup>
- Soluble reactive phosphorus – SRP
- Dissolved silicate - DSi

The second database contains in situ data collected in parallel. Continuous pCO<sub>2</sub> measurements were taken from the boat. A submersible pump was deployed from the side of the boat, pumping surface water into a degassing chamber connected to a CO<sub>2</sub> analyzer (LI-830). Data are obtained every second, 5 seconds or 30 seconds depending on the expedition, and each measurement is coupled to a GPS position.

Development of a Monitoring Protocol for Shellfish Beds on the North Shore of the Gulf of St. Lawrence

The Canadian Coast Guard (GCC) has mandated the *Zone d’Intervention Prioritaire Côte-Nord du Golfe* (ZIP CNG) Committee to develop a protocol to characterize the current health status of shellfish beds, and therefore bivalve populations, before a potential oil spill contaminates the banks, and to identify priority shellfish beds in its territory of action. The project consisted of a design stage (2023-2024) and an application stage (2024-2025). The design phase aimed to review the literature on the issues related to shellfish beds and oil spills, concluding on priority species and sites on the North Shore of the Gulf of St. Lawrence, as well as to develop a monitoring protocol to characterize the current health status of shellfish banks before a potential oil slick contaminates the banks. The application stage aimed to apply the protocol in order to test the method in the field and adjust it as needed, as well as to collect the first data on our territory. Four sites were sampled during the first year of monitoring (September 2024), one site in Port-Cartier, one site at the mouth of the Moisie River, and two sites in Rivière-Pigou.

eDrivers, a Knowledge Platform on 22 Environmental Drivers Present in the St. Lawrence System

eDrivers is an open platform focused on sharing knowledge on the distribution and intensity of drivers. It gathers a community of experts committed to structuring, standardizing and sharing knowledge on drivers of environmental change in support of science and management. The platform currently shares data-based indicators for 22 coastal, climate, fisheries, and marine traffic drivers in the Estuary and Gulf of St. Lawrence. These drivers can be visualized individually or in combination through an interactive web application called eDrivers.

In launching this initiative, our objective is to uphold the highest existing standards of data management and open science. eDrivers is built on four guiding principles: 1) Unity and Inclusiveness; 2) Findability, Accessibility, Interoperability, and Reusability (FAIR); 3) Adaptiveness; 4) Recognition. The project was presented in a publication entitled  [**Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada**](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/)  in the peer-reviewd journal Frontiers in Marine Science.

Directory of Public Access to the St. Lawrence River (1989-2009)

This Directory, produced thanks to the participation of thirty partners, contains information about public access from 46 sources previously published between 1989 and 2009. It covers the entire St. Lawrence River, from Cornwall to Blanc-Sablon, including the Magdalen Islands, Anticosti Island, and 11 priority tributaries of the 2005-2010 St. Lawrence Plan. These official data were produced as part of the St. Lawrence Action Plan 2011-2026.

Access sites are located on or near the shore. The Comités ZIP and Stratégies Saint-Laurent have partly verified data in 2010 and 2011. To make more data available, a second validation process using satellite images was made under the leadership of Public Works and Government Services Canada in three areas: the Richelieu River, the lake St. Louis and the metropolitan area of Quebec (from Cap-Rouge to Sainte-Pétronille and from Saint-Nicolas to Beaumont). SLGO then continued the validation process using Google map and Street View for all the access points on the south shore of the St. Lawrence from Île d'Orléans to Gaspé and on the north shore from Baie-Sainte-Catherine to Mingan. These last two validations result in the integration of 401 new access points throughout the territory of St. Lawrence and Richelieu Rivers.
