Ship-Based Sea Surface Dissolved CO2 (pCO2), 2013 ArcticNet, Beaufort Sea

During the ArcticNet annual cruises of the research icebreaker CCGS Amundsen, characteristics of the surface sea water (temperature, salinity, dissolved CO2 and O2) are monitored in conjunction with properties of the near-surface atmosphere (basic meteorological elements, incident radiation, CO2 concentration) to observe the relationship between the surface microclimate and the air-sea exchange, with particular interest in CO2.  Central to this integrated dataset is an under-way sea water pCO2 system (General Oceanics 8050) attached to the ship's clean water intake.  The following variables were measured continuously and logged at 1 minute intervals: pCO2sw (LI7000 gas analyzer); equilibrator water temperature; conductivity; pH; and, dissolved O2.

High-resolution survey of marine dimethylsulfide (DMS) in contrasted marine environments of the Canadian Arctic during the 2016 oceanographic ArcticNet/NETCARE campaign

The Arctic Ocean in summer is thought to be a nexus of biogenic dimethylsulfide (DMS) production associated, in part, with diversified niches within or bordering dynamic sea-ice where DMS-rich microbial communities may thrive. However, critical uncertainties remain regarding the strength of sources, sinks and efflux of marine DMS in the Arctic. Quantifying contemporary oceanic reservoirs of DMS is pivotal for the prediction and interpretation of future reservoirs of this climate-active compound. While a global DMS database of ca. 50,000 points exists, only 2.5% of these inputs originate from Arctic oceans highlighting the relevance of continued sampling efforts particularly in the context of rapid and conspicuous climate alterations in this part of the Global Ocean. A joint NETCARE-ArcticNet campaign aboard the CCGS Amundsen during July and August 2016 served as the launching platform for the deployment of a high frequency autonomous underway DMS sampling instrument (MIMS – Membrane Inlet Mass Spectrometer). Providing real-time data, the MIMS allowed the detection of surface reservoirs of oceanic DMS at greater spatial and temporal scales than traditional single-sample gas chromatography analysis, in conjunction with measurements of temperature, salinity and fluorescence (water line TSG sensor)

SX90 sonar data in the Eastern Canadian Arctic: 2011

The data set is composed of raw files recorded with the Kongsberg Maritime SX90 long-range, low frequency (20-30 kHz) fisheries sonar during the CCGS Amundsen 2011 summer expedition in the Eastern Canadian Arctic. The sonar was operated during a 3 hours opportunistic survey offshore the Labrador coast on July 22nd and during a 18.75 hours opportunistic survey on July 30th. The sonar transducer is lowered 2.5 feet below the hull through a gate-valve. The cylindrical 256-elements transducer allows both a horizontal and a vertical sound transmission, and the omni-directional (horizontal) sonar beam can be tilted from +10 to -60 degrees to scan a large portion of the water column. The raw acoustic data were saved onto an external drive and print screens of interesting targets (fish schools and/or marine mammals) were recorded.

Benthic Marine Sponges Collected from Baffin Bay, North Labrador Sea, and Davis Strait aboard the CCGS Amundsen 2015 to 2017 as part of ArcticNet HiBio Project

Sponges were sampled from multiple sites in the Northeast Atlantic from multiple cruises aboard the CCGS Amundsen. Benthic sponges were obtained through Box cores, Agassiz trawls, and through targeted sampling using the SuMO ROV. Sponges were photographed on board and in-situ when possible (using ROV camera). Collected sponges were retained for taxonomic analysis. Whole or portions of each collected sponge were preserved in 96% ethanol to prevent DNA degradation. Larger sponge fragments were frozen on board. Collected sponges are to be subsampled for morphology-based taxonomy (analysis of spicule structure and body form), and for molecular taxonomy through extraction and amplification of cytochrome oxidase subunit I (COI) mitochondrial DNA fragments for DNA barcoding. In total, 112 separate sponges were sampled during the 2015/2016 leg from depths ranging between 80-1148 metres and encompassing latitudes 60°18N to 68°15N. 31 specimens were collected using the ROV and therefore have associated in-situ video imagery which will aid in species identifications and descriptions. In total, 48 separate sponges were sampled during the 2017 leg from depths between 84 - 875 metres and encompassing latitudes 62°34N to 78°19N.  Nine specimens were collected using the ROV and therefore have associated in-situ video imagery which will aid in species identifications and descriptions. In-situ videos are not included in the dataset but will be made available upon request. See Links to data section for contact.

Arctic-SOLAS 2008 atmospheric DMS, SO2, aerosol sulfate and MSA

The database consists of hourly atmospheric DMS concentration, daily SO2 and total sulfate concentrations and three-day concentrations of size segregated aerosol sulfate. Samples were taken on the top of the navigation bridge of the CCGS Amundsen as it cruised along Baffin Bay and Lancaster Sound. Hourly samples of dimethyl sulfide was obtained using a customized DMS sampler. Samples were analyzed using a gas chromatograph fitted with a sulfur chemiluminesence detector (GC-SCD) to obtain atmospheric DMS concentrations. SO2 and total aerosol samples were obtained daily using a high volume sampler fitted with a quartz microfiber filter and K2CO3 treated cellulouse filter. Size segragated aerosol samples were obtained using a highvolume sampler fitted with slotted quartz filters on a 5 stage cascade impactor run for three days each sample. Concentrations of SO2, sulfate and MSA as well as other ions from the filter papers were obtained using ion chromatography. Delta34S values of SO2 and sulfate were obtained using a continuous flow isotope ratio mass spectrometer. Delta34S is reported based on the Vienna Canyon Diablo Troillite (V-CDT) international standard.

Strategic Environmental Intervention Plan for the Magdalen Islands Territory (2010-2014)

A vast environmental planning and consultation process on the territory of the Magdalen Islands was carried out between 2010 and 2012 by Attention FragÎles in collaboration with members of the 'Groupe de référence en environnement' (GRE). Thirty-five economic, social, cultural, and environmental organizations participated. Out of this work came the Strategic environmental intervention plan for the Magdalen Islands territory (PSIE in French), which aim to allow local and regional stakeholders to base their policies and actions on a coherent and shared strategic vision for the Magdalen Islands, as well as to provide a guideline for action on the territory. 

The plan includes a detailed environmental profile of the territory, an overview of environmental actions that have been carried out, an assessment that prioritizes the most critical territorial risks and challenges, ten general directions, and a series of options and strategic interventions to address the identified challenges. The final version of the PSIE was completed in 2012, and an online platform was created. A summary was produced in 2014 to help local collaborators take ownership of the plan. The PSIE was also used as grounds for tabling an environmental policy by the Communauté Maritime des Îles-de-la-Madeleine in 2016.

Restoring Fish Habitat in the Saint-Georges Canal in Port-Menier, Anticosti Island

The main objective of this project was to restore wildlife connectivity by allowing fish to circulate between the Gulf of St. Lawrence and Lake Saint-Georges, in Port-Menier, on Anticosti Island. It also aimed to improve the ecological characteristics of fish habitat in the Saint-Georges Canal by creating wildlife improvements and restoring its shores. The actions taken to achieve these goals, between 2020 and 2022, consisted in developing two migratory passages and fish habitats, removing anthropogenic elements as well as transforming two existing dams that prevented the movement of fish to allow the creation of migration routes.

Database on Marine Seaweeds From the Sites of the Magdalen Islands Region (2019)

In order to contribute to the development of seaweed farming in the province of Quebec, Merinov, in collaboration with the University of Quebec at Rimouski, is working within the framework of the interregional program OPTIMAL launched in 2014. Various brown seaweed cultivation trials have been carried out in recent years to identify sites with environmental characteristics corresponding to optimal parameters for the growth of sweet kelp (Saccharina latissima). In 2018, a mapping of potential sites was established on the basis of already existing biotic and abiotic data.

Thus, in the Magdalen Islands, production sea trials were carried out on three selected sites, namely New Hall, Étang du Nord and Bassin from 2018 to 2019. The kelp spawners were harvested at Rocher aux Oiseaux in September 2018. Sporulation and inoculation of the collectors were carried out in the laboratories of Merinov. At each site, seaweed seedling wetting devices were launched at different depths. The cords of seedling were rolled up at different positions on the wetting device. The seaweeds were collected during the period from May 2019 to July 2019. Environmental and biomass data were collected.

Port of Halifax Water Bird Surveys, Nova Scotia, Canada (2024)

From spring to winter 2024, point count waterbird surveys are being conducted at 15 sites across Halifax, Nova Scotia, Canada. This effort will continue through 2026. These surveys take place seasonally, focusing on select times in the fall, spring, summer, and winter. During each survey, data is collected on species identification, the number of individuals present, general behaviour such as resting, feeding, or flying, disturbances, and the birds' general location relative to the shore, categorized as inshore, nearshore, or offshore. Site-specific environmental conditions are also recorded, including weather variables like precipitation, wind, and cloud cover, as well as tidal state and movement, sea state, visibility, glare, and human activity at the sites.

These surveys are part of the Coastal Environmental Baseline Program under the Oceans Protection Plan, managed by Fisheries and Oceans Canada. With increased ship traffic and oil facilities, particularly in areas like Halifax Harbour and the Port of Sydney, waterbirds face significant risks, particularly from oil spills. The Migratory Birds Regulations prohibit harm to migratory birds in Canada, yet the threats from coastal industrial activity persist. This project aims to better understand where waterbirds are and when they are present in these harbours, helping improve protection measures during environmental incidents such as oil spills.

The Port of Sydney bird survey dataset related to this project is also available for consultation:

Interactive Map to Preserve the Integrity of the St. Lawrence

In 2023, this project made it possible to create an interactive map for the general public. It lists all the accessible sites along the coastline of the Haute-Côte-Nord and Manicouagan MRCs, from Sacré-Coeur to Baie-Trinité. This map identifies the location of hiking trails, boat launches, lookouts, observation sites, sport fishing sites, and several other places of interest to residents and travelers. This work was carried out with the participation of coastal municipalities as well as Innu communities. The objective of this project is to encourage citizens and travelers to use the infrastructures already in place in order to avoid human pressure in fragile areas along the coastline (wildlife habitats, heronries, wetlands, etc.).

This project is possible thanks to the Maritime Affluents Program administered by the Saint-Laurent Action Fund (FASL) and coordinated by the *Regroupement des organismes de bassins versants du Québec* (ROBVQ), as well as to the financial support of the Government of Quebec as part of Avantage Saint-Laurent, the new provincial maritime vision. The Quebec Wildlife Foundation's Act for Wildlife program also financially supported this project. We would also like to highlight the participation of Côte-Nord Tourism and Matrivex Geospatial in the realization of this project.

Voir la Mer: Underwater Archaeological Inventory in the Parc du Bic (2019)

This underwater archaeological inventory was carried out in the Parc du Bic during the summer of 2019. It is part of a multidisciplinary approach undertaken with the Voir la Mer project, funded by the Odyssée program of the Réseau du Québec Maritime. This archaeology study includes a methodological description and the environmental description of the Bic. The historical section adresses the human occupation of the Bic based on archived documents, archaeological, and recent data. This provides the opportunity to identify coastal areas of archaeological interest. Lastly, an inventory of recorded shipwrecks and maritime incidents was created with the combination of different sources in order to target areas with high underwater archaeological potential.

The intervention included an underwater archaeological survey by remote sensing using three geophysical instruments: the side-scan sonar, the multibeam sounder, and the subsurface profiler. It was carried out between July 15 and August 2, 2019. 

This document is the archaeological mission report as presented to the Ministère de la Culture et des Communications du Québec.

Commercial fisheries intensity, Driver of Environmental Change: eDrivers Project for the St.Lawrence System

The impacts of fisheries activities in the St. Lawrence are evaluated using DFO fisheries logbooks program. While logbooks are not mandatory for all fisheries in the St. Lawrence, they still provide a very thorough overview of the spatial distribution and intensity of fishing activities in the St. Lawrence. The data we used spans 6 years from 2010 to 2015 and details 218323 fishing events (approximately 36387 fishing events per year). There were 31 targeted species and a total of 53 caught species in the dataset.

Fishing activities are performed using a variety of gear types: trap, trawl, dredge, driftnet, hand line, longline, scuba diving, purse seine, seine, beach seine and jig fishing. Intensity of fishing activities was divided among gear types and based on their respective types of environmental impacts. For example, traps and trawls have very different effects on a system. Gear classification was done using the classification presented in [Halpern et al. (2008)](https://www.science.org/doi/10.1126/science.1149345) and [Halpern et al. (2015a)](https://knb.ecoinformatics.org/view/doi:10.5063/F1S180FS) and is broken down into 5 distinct classes: demersal destructive (DD), demersal non-destructive low-bycatch (DNL), demersal non-destructive high-bycatch (DNH), pelagic low-bycatch (PLB) and pelagic high-bycatch (PHB). This categorization therefore divides the fisheries data into 5 distinct driver layers characterizing fishing activities. Gear types can also be further classified into fixed or mobile engines based on their mobility. We used these two mobility classes to generate a buffer of impact around each fishing activity coordinates to consider potential spatial uncertainty associated with locations and the fact that mobile engines can be tracted over several kilometers during fishing activities and that we do not have the beginning and end points of mobile fishing events. Buffer sizes for fixed and mobile engine was of 200 and 2000 meters, respectively. To characterize the intensity of fishing activities we used a biomass yield density index. We multiplied the total annual biomass captured in each grid cell, regardless of species, by the proportion of fishing area in each grid cell.
