Physico-Chemical and Carbonate Chemistry Parameters in the Shallow Coastal Zone of Pointe-au-Père (St. Lawrence Estuary)

This dataset contains all physico-chemical parameters measured during the ice-free months in 2023 and 2024 in the shallow coastal waters of Pointe-au-Père, located in the Lower St. Lawrence Estuary. During these periods, high-frequency measurements were taken every 15 minutes using autonomous data loggers (HOBO) attached to a mooring to monitor pH and other physicochemical parameters. This structure was deployed in the subtidal zone, near rocks covered by crustose coralline algae and kelp, located less than 50 m from the shore, with up to 6 m of water column depending on the tide. 

To mitigate biofouling, divers cleaned all sensors every 1-2 weeks by gently brushing them underwater. Note that in 2024, there is a gap from May 15th to 21st, following a partial burial after an important sediment resuspension event. In addition to continuous monitoring, discrete water samples were collected just above the mooring, every 1-2 weeks to measure total alkalinity, dissolved inorganic carbon and pH. Calibration and processing of certain data measured by the HOBO sensors were performed:  

- Voltage (*mV*) measurements from the pH HOBO were converted to total scale (pHT) using a multi-step calibration with TRIS buffer solutions. 
- Light data from the HOBO sensor (*lux*) were converted to Photosynthetic Active Radiation (PAR; *μmol photons m⁻² s⁻¹*) using a linear calibration against a miniPAR sensor. 
- Water level was calculated from the absolute pressure (*kPa*) of the HOBO and corrected for the atmospheric pressure of the Pointe-au-Père meteorological station.

The data are divided into two databases. The first contains all **high-frequency measurements**, taken every 15 minutes:  

- pH (*mV*)
- pH (total scale)
- Temperature (*°C*)
- Practical salinity
- Light (*lux*)
- Light (PAR; *μmol photons m⁻² s⁻¹*)
- Absolute pressure (*kPa*)
- Water level (*m*)
- Aragonite saturation state (omega aragonite; calculated)
- Omega calcite (calculated)

The second database contains the data of the **discrete samples**:  

- pH (total scale) measured by spectrophotometer at 25°C.
- Total alkalinity (*µmol/kg*) measured by potentiometric titration.
- Dissolved inorganic carbon (*µmol/kg*) measured by a DIC analyzer.

Eelgrass (Z. marina) extent at Gulf Islands National Park Reserve eelgrass monitoring sites (2024)

This data package contains the datasets and reports pertaining to mapping the spatial extent of Zostera marina at several monitoring sites within the Gulf Islands National Park Reserve, British Columbia, Canada. This work was a collaborative project between the Hakai Institute and the Gulf Islands National Park Reserve (GINPR).  

Four eelgrass monitoring sites were mapped in partnership with the Hakai Institute and Gulf Islands National Park Reserve in 2024. Three eelgrass monitoring sites (James Bay, Tumbo, Cabbage) were mapped using small Remotely Piloted Aerial Systems (RPAS), and a fourth site, Sidney Spit, was mapped by the Hakai Aerial Coastal Observatory (ACO) - a fixed-wing aircraft with two medium format cameras (RGB and NIR). Orthomosaics of each site were generated using a Structure from Motion Multi-View Stereo (SfM-MVS) workflow in Agisoft Metashape (Version 2.1.61, Pix4D) in Windows 10. Orthomosaics were georeferenced to either previous surveys (James Bay, Cabbage, Tumbo) or using post-processed GNSS data with onboard IMU data in the case of the ACO survey. 
The extent of eelgrass at each site was delineated using object-based image analysis (OBIA) with eCognition Developer software (eCognition Developer 10.1, 2014) and manual delineation (where necessary). Georeferenced towed underwater video (SplashCam Pro) data were collected at eelgrass monitoring sites to provide ground-truth data for verifying eelgrass extent. 

The data package includes:

-  The report (.pdf) which describe the project, data collection, processing methods and results for the 2024 surveys. Comparison to previous eelgrass surveys is also included.
-   A report (.pdf) which describes the Aerial Coastal Observatory (ACO) survey methods and equipment.
-   Polygon shapefiles (.shp) of the extent of eelgrass (Z. marina) at each monitoring site.
-   Point shapefiles (.shp) of classified towed underwater video transects*. 
-   A data dictionary (.csv) which describes the attributes of the eelgrass and towed video shapefiles. 
-   For Sidney Spit - field photos and transect surveys of eelgrass and green algae are provided as shapefiles.

*The towed underwater video footage is not available.  

This data package is a component of the Hakai Institute’s Habitat Mapping program whose overarching objective is to generate spatial inventories of coastal habitats, investigate how these habitats are changing through time and the drivers of that change. These data were collected as a part of the Coastal BC Nearshore Habitat Mapping Project (a collaboration between Parks Canada and the Hakai Institute).

Barnacle Dynamics: Point Intercept Surveys - BC Central Coast - 2016-2018

The barnacle dynamics dataset is a component of the Hakai Institute’s Nearshore research and monitoring program, designed to capture change in rocky intertidal habitats. The overarching objective of Hakai Nearshore research is to investigate the role of habitats and their associated communities, in the face of stress and disturbances from global climate change and local coastal perturbations. 

The barnacle community was assessed from 2016-2018 at three coastal sites along the northwest edge of Calvert Island on the Central Coast of British Columbia. All three sites were exposed rocky shorelines with contiguous zones of substrate dominated by species of barnacle. The abundance and diversity of the barnacle species within these zones was surveyed using point-intercepts within permanent plots. The sites were surveyed on an approximately monthly basis from May-September, and two winter surveys in November and February.  Six surveys were conducted in 2018, 5 in 2017, and 3 in 2016. 

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.

Dissolved organic carbon fluxes of seven watersheds in a bog forest ecosystem at Calvert Island, British Columbia, Canada

Scientific report on catchment responses and organic carbon fluxes for seven rivers draining into Kwakshua Channel (Calvert Island, BC, Canada) for a summer and early fall rain event in 2014.

The coastal temperate rainforest of western British Columbia is a major store of carbon and an important contributor to the global carbon cycle. The flux of dissolved organic carbon from wetland-dominated soils is of vital importance for coastal freshwater and marine ecosystems. The objective of this study was to investigate the relation between discharge, DOC concentration and organic carbon flux for seven wetland and bog forest dominated watersheds for a summer and early fall rain event. Stream water samples were taken along the rising and falling limb of the event hydrographs at the outlets of all seven watersheds and analyzed for DOC concentration. Stream DOC concentration increased along the rising limb and decreased back to a stable concentration under base flow conditions. The relation between discharge and flux of organic carbon was characterized by hysteresis; there was a delay in peak carbon flux compared to peak discharge for all studied watersheds. The amount of organic carbon exported over the course of a rain event was directly related to the fraction of rain exported as runoff. Total event organic carbon load for six out of seven watersheds was 233 kg km-2 for the summer event and 204 kg km-2 for the early fall event. The export of organic carbon per day was twice as high for the shorter and more intensive early fall event than the summer event.
