Underway surface seawater and marine boundary layer observations made from the Alaska Marine Highway System M/V Columbia from October 2017 to October 2018

From October 2017 to October 2018, underway surface water measurements were collected from the Alaska Marine Highway System M/V Columbia during 81 service route transits. The service route of the Columbia included the ports of Sitka, Juneau, Haines, Skagway, Wrangell, Petersburg, and Ketchikan in southeast Alaska, and between Ketchikan and Bellingham, WA. The vessel sailed from Ketchikan every Wednesday, arrived in Bellingham on Friday, and returned to Ketchikan on Sunday. Measurements of temperature, salinity, dissolved oxygen content, and CO2 partial pressure were made every 2 mins on seawater drawn into the vessel from a ~2 m intake. Seawater was delivered from the intake to analytical equipment on the car deck using a AMT 1/2 HP pump (4295-98). Temperature and salinity data were collected using a Sea-Bird SBE 45 MicroTSG Thermosalinograph, and intake temperature measured using a SBE 38 Digital Oceanographic Thermometer. Dissolved oxygen content was determined using an Aanderaa 4330F that had undergone multipoint calibration. CO2 measurements were made using a General Oceanics 8050 (GO8050) pCO2 Measuring System. All data streams, including GPS information from an antenna and atmospheric pressure from a Druck barometer positioned on the foredeck, were captured by the GO8050 control computer. Atmospheric CO2 measurements were also made using the GO8050 on unaltered marine air drawn to the system through an intake located on the foredeck. The CO2 measurement scheme involved the analysis of four gas standards of known CO2 content (150 ppm, 349 ppm, 449 ppm, and 850 ppm; Praxair), 12 analyses atmospheric CO2, and 240 seawater CO2 measurements in a cycle that was repeated every 8.5 hours. The seawater and atmospheric CO2 analyses were run in a sequence of 3 atmospheric measurements and 60 seawater measurements that was repeated 4 times between standardization. This project was supported by the Tula Foundation and Alaska Ocean Observing System, and was a collaborative effort between the Hakai Institute, University of Washington Joint Institute for the Study of the Atmosphere and Ocean/NOAA Pacific Marine Environmental Laboratory, State of Alaska Department of Transportation, University of Alaska Southeast Alaska Coastal Rainforest Center, and the Alaska Ocean Observing System.

Nereocystis kelp canopy productivity data from BC Central Coast

The nereocystis canopy production dataset is a component of Hakai Institute’s Nearshore research and monitoring program. This dataset documents seasonal changes in Nereocystis luetkeana density, size structure and growth parameters at multiple locations near Calvert Island on the Central Coast of British Columbia (BC) since 2016.  Each year, sites were visited 1 - 5 times over the summer months (April-September) and 0 - 2 times over the winter months. Fifteen plants were tagged at each site to measure individual stipe growth, blade elongation, blade erosion, change in number of blades and plant survival. Additional plants (up to 45 per site) were measured for stipe and blade size structure distributions. Three permanent transect lines were used to track change in plant density and relocate the tagged plants. Blade growth rate ranged from 0 to 15 cm per day through the summer months and stipe growth ranged from 0 to 12 cm a day, depending on site and time of year. Based on these data we can determine which field parameters best correlate with overall kelp productivity and biomass, to refine metrics for long-term assessments of Nereocystis luetkeana status in BC and ultimately find what environment factors are driving these local temporal and spatial trends.
This data package is freely available to everyone, following the principles of equitable access and benefit sharing. However, we expect all data users to give attribution to the data providers (read our data license) and the use of these data should happen in the light of fair use, i.e.: 1) respect the data providers, and provide helpful feedback on data quality, and 2) communicate and/or collaborate with the providers if you are considering using this dataset for manuscripts or other forms of reporting.

Kelp extent for the McNaughton Group Islands (2017), Manley Island (2017), and Serpent Group Islands (2016), British Columbia, Canada

This is a polygon layer mapping kelp canopy extent for the McNaughton Group islands, Manley Island, and Serpent Group Islands.

Kelp canopy extent was mapped from imagery taken using an unoccupied aerial system (UAS). McNaughton Imagery was taken in late May 2017, the Manley images were captured in late July 2017, and the Serpent Group images were made in early July 2016. The images were captured using a DJI Phantom 3 professional UAS equipped with a commercial grade 4k RGB (See attached UAS methods). Kelp bed polygons were drawn manually in ArcGIS 10.5.1. Only beds containing greater than ~3 fronds were mapped. Beds were considered connected when less than ~5m separated them. Single fronds and single frond outliers were not digitized. Vertices were placed every 4m or less (more vertices were used on complex shapes). The attributes in this table are limited to the perimeter length (m) and area (m^2) of each kelp bed polygon. Area was determined in the NAD_1983_CSRS_BC_Environment_Albers projection. Species and bed density were not recorded for this dataset.

Tidal Marshes in the Maritime Coastal Zone of Quebec

This dataset was designed for Environment and Climate Change Canada's (ECCC) National Environmental Emergencies Center (NEEC) for oil spill preparedness and response. The polygons from this layer come from the coastal ecosystems geodatabase as part of the Mapping of coastal ecosystems of the Estuary and Gulf of St. Lawrence project. This layer represents semi-vegetated (25-75%) and vegetated (75-100%) zones of which marsh vegetation is the dominant. The study area includes all of the estuarine and maritime coasts of Quebec, with the exception of certain sectors, including most of the Lower North Shore and Anticosti Island, with the exception of villages of Kegaska, la Romaine, Chevery, Blanc-Sablon and Port-Menier. Some islands off the estuary and gulf coasts are part of the region covered, such as Île d'Orléans, Isle-aux-Coudres, Île Verte and Île Bonaventure.

The mapping of coastal ecosystems was carried out jointly by the Laboratory for Dynamics and Integrated Coastal Zone Management (LDGIZC) of the University of Quebec at Rimouski as part of the [**Coastal Resilience Project**](https: //ldgizc.uqar.ca/Web/projets/projet-resilience-cotiere) funded by the MELCC; and by the Fisheries and Oceans Canada team, as part of its Integrated marine response planning (IMRP) component of the Oceans Protection Plan (OPP), with the objective of updating the Marine Oil Spill Preparedness and Response Regime of Canada. The master geodatabase of coastal ecosystems is hosted and distributed by UQAR on their [**SIGEC-Web mapping platform**](https://ldgizc.uqar.ca/Web/sigecweb)

The characterization of marshes was mainly carried out using photo-interpretation of RVBI aerial photos acquired by DFO (2015-2020) and oblique photos taken by helicopter acquired by UQAR in 2017. This dataset also includes the information from validation stations visited by UQAR (2018-2020), used to validate and refine the photo-interpretation.

Bald eagles as vectors of marine nutrients – Central Coast Islands (100 Islands study area) – May – July 2017

In this observational study, we quantify the relationship between eagle activity, soil chemistry, and vegetation composition.  This dataset consists of plot description, eagle and reference tree information, vegetation data, and soil chemistry data. Data is in tabular form.

Based on foraging behavior and nesting habits, I propose that bald eagles (Haliaeetus leucocephalus) are an important vector of marine nutrient transfer. Although their diet is largely marine-based, bald eagles generally consume their prey on land. This behavior results in deposition of guano and prey remains that are likely chemically or nutritionally similar to seabird guano and may produce similar ecological responses. Altered soil characteristics may include increased concentration of marine-derived nitrogen (δ15N), total nitrogen, and phosphorous, and decreased pH. Previous research shows a correlation between changes in soil chemistry and an increase in plant biomass and decrease in plant species richness at seabird colony sites, presumably because certain plant species were able to dominate under high nutrient-low pH conditions. If long-term additions of nitrogen from bald eagle guano and prey remains do change soil chemistry, a shift toward more nitrophilous species may be most evident in the homogenous, salal-dominated understories of Central Coast islands.

R/V Coriolis II expedition TCA-MEOPAR – COR2025 HOLOCENE SAGUENAY

This cruise report describes the R/V Coriolis II expedition TCA-MEOPAR – COR2025 HOLOCENE SAGUENAY. The mission is part of the TCA cluster 1.1. UncertainSea, workpackage Land-to-Sea, which aims to investigate land-to-ocean matter fluxes in various fjords along a latitudinal transect from the Saguenay Fjord, Québec, to Croker Bay, Devon Island, Canada throughout the Holocene. 
This cruise was dedicated to sample sediment cores from the head of the Saguenay, at the mouth of Baie Des Ha! Ha!, and in the central upper fjord near Grosse-Ile. Gravity coring was performed to retrieve long sedimentary sequences with sufficient resolution to capture natural climatic, sedimentological, and depositional changes. Parallel cores from each sampling site were obtained to allow analysis of a multitude of non-destructive and destructive proxies. In addition to gravity coring, surface samples from within and outside the fjord were obtained by multicorer (to sample the water-sediment interface, including the fluffy layer, and uppermost sediment samples) and boxcorer (for 3D imaging of the uppermost sediment).

Water Governance in the St. Lawrence River Basin

Recent events at the local and federal levels in the United States have rekindled the debate about the sustainability of water governance in the North American Great Lakes. This governance is adaptive, responding to the contemporary concerns of governments, thus addressing specific issues in turn. It is only recently that governance at several levels, national, state and municipal, has taken shape, and aimed at integrating a wide range of issues.

Northwest Calvert sea wrack temporal data, Central Coast, British Columbia (2016-2017)

This dataset contains the collection site locations, visit dates, and weights of each species of shore cast algae or seagrass found during each site visit.

Dead, shore-cast seaweeds and seagrasses (commonly called sea wrack) provide an important vector of marine-derived nutrients to low productivity terrestrial environments, such as beaches. However, little is known about the processes that facilitate wrack transport, deposition, and accumulation in coastal temperate British Columbia. Throughout the course of one year, I visited three sites on a bi-monthly basis to document temporal changes in wrack biomass and species composition. At each site, wrack was measured along 12 permanent 1-meter wide belt-transects. The transects ran perpendicular to the water's edge, originating at the forest-beach interface and extending to the ocean at low tide. I found wrack biomass to be similar throughout all four seasons, wrack species composition, however, varied. My results suggest sea wrack is a consistent vector of potential nutrients from the marine to the terrestrial environment in British Columbia.

Gulf of St. Lawrence and Estuary Dataset (GOSLED): A 20-Year Compilation of Quality-Controlled Biogeochemical Observations (2003–2023)

This dataset includes 20 years (2003–2023) of biogeochemical observations collected during 21 dedicated research cruises in the Estuary and Gulf of St. Lawrence as well as its main tributary, the Saguenay Fjord. The dataset contains CTD sensor measurements of pressure, temperature, practical salinity, and dissolved oxygen, as well as discrete oxygen measurements determined by Winkler titration. Additionally, the dataset includes discrete carbonate-system parameters such as dissolved inorganic carbon, total alkalinity, pH (total proton scale), and the fugacity of CO₂, along with macronutrient concentrations (nitrate, nitrite, ammonium, soluble reactive phosphate, and silicate). Organic parameters such as dissolved organic carbon and total nitrogen are included, as are the concentrations of selected biogeochemical gases (e.g., nitrous oxide) and the stable carbon isotopic composition of the DIC and DOC, as well as the δ¹⁸O and δD of H₂O. Measured transient tracers include CFC-12 and SF₆ and a deliberate tracer, CF₃SF₅. Data were compiled from both historical measurements (2003–2020) and recent sampling efforts from the [MEOPAR–RQM *TReX* project (2021–2023)](https://meopar.ca/research/trex-project/) and [RQM - *Odyssée Saint Laurent* program (2018-2023)](https://www.rqm.quebec/odyssee-saint-laurent/). All data were processed following primary quality control procedures adapted from GLODAP and CODAP-NA standards. Secondary crossover analysis was not possible due to a lack of deep-water sampling. This dataset is a rare, quality-controlled biogeochemical time series for the Gulf and St. Lawrence Estuary and provides a baseline for future research on deoxygenation, acidification, and nutrient cycling in Eastern Canada.

Sea wrack wet to dry biomass calibrations for macroalgae of the Central Coast of British Columbia - 2018

This dataset contains species-specific standardized correction factors for wet-dry calibrations for several macroalgae species of the Central Coast of British Columbia.

Macroalgae and macrophytes form the base of productive ecosystems in the Northeastern Pacific Ocean. Often, ecological research on macrophytes, macroalgae, and sea wrack requires the conversion of biomass from wet to dry to create consistency across investigations. This process, however, can be impractical, time consuming, and labour intensive. Samples of 12 common Northeastern Pacific Ocean seaweed species (Alaria marginata, Codium fragile, Egregia menziesii, Fucus distichus, Macrocystis pyrifera, Mazzaella spp., Nereocystis luetkeana, Pterygophora californica, Pyropia spp., Ulva spp., and the seagrasses Zostera marina and Phyllospadix spp.) were collected randomly and opportunistically in two states: wet and fresh, or aged and partially desiccated. Samples were weighed, dried in an oven, and weighed again in a laboratory as quickly as possible after collection. Dried samples were disposed of after dry measurements were taken. Detailed methods are available in the in the linked folder.

We found that all species displayed a strong (R2 > 0.5) and predictable (p < 0.05) linear relationship between wet and dried conditions. Half of the aged samples did not have a significant relationship between partially desiccated and dried conditions. These results offer a reliable set of species-specific standardized correction factors for wet samples that can be used in future macrophyte, macroalgae, and sea wrack research, reducing the need to conduct extensive wet-dry calibrations in future studies.

Underway Surface Seawater and Marine Boundary Layer Observations from the M/V Columbia (Research)

Between October 2017 and October 2019, underway surface water measurements were collected from the Alaska Marine Highway System M/V Columbia during 135 service route transits. The service route of the Columbia included the ports of Sitka, Juneau, Haines, Skagway, Wrangell, Petersburg, and Ketchikan in southeast Alaska, and between Ketchikan and Bellingham, WA. The vessel sailed south from Ketchikan every Wednesday, arrived in Bellingham on Friday, returned to Ketchikan on Sunday, and transited between southeast Alaska terminals between Sunday and Wednesday. Measurements of temperature, salinity, dissolved oxygen content, and CO2 partial pressure were made every 2 mins on seawater drawn into the vessel from a ~2 m intake. Seawater was delivered from the intake to analytical equipment on the car deck using a AMT 1/2 HP pump (4295-98). Temperature and salinity data were collected using a Sea-Bird SBE 45 MicroTSG Thermosalinograph, and intake temperature measured using a SBE 38 Digital Oceanographic Thermometer. Dissolved oxygen content was determined using an Aanderaa 4330F that had undergone multipoint calibration at the factory in Norway. CO2 measurements were made using a General Oceanics 8050 (GO8050) pCO2 Measuring System equipped with a LI-COR LI840A non-dispersive infrared detector. All data streams, including GPS information from an antenna and atmospheric pressure from a Vaisala barometer positioned on the foredeck, were captured by the GO8050 control computer. Atmospheric CO2 measurements were also made using the GO8050 on unaltered marine air drawn to the system through an intake located on the foredeck. The CO2 measurement scheme involved the analysis of four gas standards of known CO2 content (150 ppm, 349 ppm, 449 ppm, and 850 ppm; Praxair Distributions Inc), 12 analyses atmospheric CO2, and 240 seawater CO2 measurements in a 8.5 hour period. The atmospheric and seawater CO2 analyses were run in a sequence of 3 atmospheric measurements and 60 seawater measurements that was repeated 4 times between standardization. This project was supported by the Tula Foundation and Alaska Ocean Observing System, and was a collaborative effort between the Hakai Institute, University of Washington Joint Institute for the Study of the Atmosphere and Ocean/NOAA Pacific Marine Environmental Laboratory, State of Alaska Department of Transportation, University of Alaska Southeast Alaska Coastal Rainforest Center, and the Alaska Ocean Observing System.
