Eelgrass Extent - Coastal British Columbia

Keywords: None
Temporal coverage: None

This dataset represents polygons of eelgrass on the BC coast predicted from existing geospatial datasets of seagrass extent (ShoreZone) and bathymetry.

The extent of eelgrass in British Columbia was estimated using a novel tool created for ArcGIS (the Gregrator).This tool requires 2 inputs: (1) the coastline data from Shorezone (including line shapefiles that represent the extent of eelgrass) and (2) bathymetry data. Briefly, each line segment of coast in ShoreZone is converted to points along its vertices. These points are used to generate Thiessen polygons, where each Thiessen polygon “defines an area of influence around its sample point, so that any location inside the polygons is closer to that point than any of the other sample points” (Esri, 2016). Thiessen polygons were then clipped to the extent of polygons which spanned the area from the coastline to maximum depth based on the results of the bathymetry analysis. These methods are based on those described in Gregr et al 2013.

Understory kelp biomass data from BC Central Coast, 2014-2020

Keywords: None
Temporal coverage: None

The understory kelp biomass dataset is a component of Hakai Institute’s Nearshore research and monitoring program. This dataset characterizes spatial and temporal trends in understory kelps and kelp-consuming invertebrate communities at 22 rocky bottom subtidal sites near Calvert Island on the Central Coast of British Columbia (2014-2020). Data coverage varies by year. The total length and abundance of all kelps, Desmarestia species, and urchins were measured at 6 sites, seasonally (5 times within a year) from 2014-2017. Urchin behaviour was also recorded. From 2016-2019, additional sites (4-15) were surveyed annually using a variation on the sampling design (reduced measurements on subset of sites). In 2018-19 kelp consumer species abundance, including small mobile grazing invertebrates were recorded. Dry weight values and length to weight relations are also provided to extrapolate density and morphology data to biomass. Spatial and temporal variability in kelp and invertebrate community relationships is described.

Kelp Canopy Extent - 2015 - NW Calvert Island - British Columbia - Canada

Keywords: None
Temporal coverage: None

Kelp Canopy Extent - 2015 - NW Calvert Island - British Columbia - Canada

Digitized kelp extent, species, and density for NW Calvert Island in the summer of 2015.

This methodology outlines the procedure for obtaining and processing high-resolution imagery of the canopy-forming kelp beds in the Northwest Calvert Island area. It also includes the procedure for data analysis and metrics of interest to be monitored over time.

Aerial Survey Area
The survey for annual kelp bed mapping extends south from Starfish Island in Choked Pass to 7th Beach - NW Calvert Island, British Columbia, Canada.

Survey timing protocols are framed by the goal of obtaining imagery that best represents the maximum extent of the canopy-forming kelps. Based on optimizing the timing of maximum canopy development, tide level, and light conditions, we select acceptable “survey windows” at the beginning of each season. Firstly, survey windows occur during the period of maximum canopy extent, generally considered to be between August and October in British Columbia. Secondly, survey windows are determined by the timing of low tide cycles, such that all imagery is captured at tide heights lower than +1.0 m MLW.

Imagery Capture: Surveys are conducted using DJI Phantom 3 professional Unmanned Aerial Vehicles (UAVs or drones) equipped with a commercial grade 4k RGB camera to capture imagery. The UAV and camera are operated by using the DJI Capture software application connected to a tablet or smartphone.

Kelp extent layer is represented by polygons which were digitized manually in ARC GIS.

Attributes: Density, Area, Confidence, and Species.

Seagrass Site-Level Production Data Package v1.0.0

Keywords: None
Temporal coverage: 2015-05-27T00:00:00

The Seagrass Site-Level Production dataset is a component of Hakai Institute’s Nearshore research and monitoring program, designed to determine the drivers of change in seagrass ecosystems. 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.

This data package contains seagrass (Zostera marina) primary production observations collected from May 2015 to Feb 2019, at long-term seagrass meadow monitoring sites on British Columbia’s Central Coast. SCUBA divers collected data from 9 sites annually and 1-3 sites seasonally along permanent 30m transects. Primary productivity data was collected during two concurrent, but separate surveys (i.e., different parameters, methodologies, and sample designs). The data files included in this data package are: 1) ‘Habitat’ surveys, focused on landscape-level habitat variables (e.g., substrate type, subdominant vegetation, adjacent habitat types, seagrass patchiness), and 2) ‘Density’ surveys measuring seagrass specific variables at a finer scale (e.g., seagrass shoot density, and canopy height). Data included here are a subset of the Hakai Institute’s seagrass monitoring dataset.

Mean Tidal Current - Coastal British Columbia - Canada

Keywords: None
Temporal coverage: None

Tidal Currents is a raster layer where each pixel represents root mean square (RMS) average tidal speeds (m/s) over a large number of tidal cycles. Raster resolution 500 by 500 m. Data from 2008. Original data was provided by BCMCA, and projected to BC Albers- reprojected for online use in WGS84 Web Mercator Auxiliary Sphere by Keith Holmes. More information about the original data and model used in Foreman et al, 2000.

The purpose of this dataset is to identify RMS tidal speeds within the Canadian Pacific EEZ to help inform the physical feature identified in the BCMCA Physical Report. Data presented as 2 km x 2 km planning units for MARXAN analysis.

Root Mean Square (RMS) of tidal speeds. RMS tidal speed is output from a 3-D diagnostic circulation model for the Northeastern Pacific Ocean (Dr. Mike Foreman, Department of Fisheries and Oceans). The modelled tidal speeds are barotropic, meaning density is not taken into account. The points extracted from this model were displayed and then converted into a raster.

Water column CO2 system measurements collected during the 2016 National Oceanic and Atmospheric Administration West Coast Ocean Acidification survey (NOAA WCOA2016) from California to British Columbia

Keywords: None
Temporal coverage: None

Carbon dioxide partial pressure (pCO2) and total dissolved inorganic carbon (TCO2) measurements were made on seawater collected from 12 depths at select stations occupied during the 2016 National Oceanic and Atmospheric Administration West Coast Ocean Acidification survey (NOAA WCOA2016) from California to British Columbia. NOAA cruise data collected during this survey are available from the National Centers for Environmental Information (https://www.nodc.noaa.gov/ocads/oceans/Coastal/WCOA.html). Hakai Institute staff (Evans) collected data only during the second leg of the survey from May 24 to June 7. Information describing the cruise plan and cruise blog can be found on the NOAA Pacific Marine Environmental Laboratory (PMEL) website (https://www.pmel.noaa.gov/co2/story/2016+West+Coast+Ocean+Acidification+Cruise). Seawater sampling during this cruise was conducted using a conductivity-temperature-depth (CTD) profiler coupled with a 24-Niskin (11-L) bottle rosette. Seawater collection was concentrated in the upper 200 m at standard depths: 3 m, 10 m, 20 m, 30 m, 50 m, 80 m, 100 m, 125 m, 150 m, and 200 m. Two additional deeper depths were sampled when the water column exceeded 200 m. Additional shallow depths were sampled at the Hakai Institute’s oceanographic station QU39 (http://dx.doi.org/10.21966/1.715738). Samples were drawn from the Niskin bottles with care not to introduce bubbles into 350 mL amber glass bottles using silicone tubing, and left with 3 mL of headspace. Samples were then fixed with 200 µL of mercuric chloride and crimp-sealed with polyethylene-lined metal caps. Samples were stored in the dark and at room temperature until analysis on the Hakai Institute’s Burke-o-Lator (BoL). For detailed protocols on data processing including CO2 system determination, and quality assurance, please see Pocock et al. (2017; http://dx.doi.org/10.21966/1.521066). Final CO2 system parameters (pHT, pCO2, and aragonite saturature state) were computed using (primary) CTD temperature and salinity, and BoL determined total CO2 (TCO2) corrected using certified reference materials and alkalinity (Alk) using the carbonic acid dissociation constants of Lueker et al. (2000). Calculations were done relative to in situ pressure. Note Alk here is assumed here to consist of carbonate, bicarbonate, borate, hydroxide, and hydrogen ions; neglecting the influence of nutrients and organic acids. The effort to collect these data are part of the Hakai Institute’s directive to advance the understanding of carbon cycling in northeast Pacific coastal settings with specific emphasis on ocean acidification.
Aquatic carbon flux data package for Oliver et al. 2017

Keywords: None
Temporal coverage: 2014-10-01/2016-05-18

Overview
This chemistry dataset was used to assess patterns in watershed export of dissolved organic carbon (DOC) concentrations, DOC flux, and characterization of dissolved organic matter (DOM) for preparation and publication of the manuscript: Oliver et al. 2017, Globally-significant yields of dissolved organic carbon from small watersheds of the Pacific coastal temperate rainforest, doi: 10.5194/bg-2017-5, Biogeosciences. Chemistry and discharge data were collected from the stream outlet stations of the seven focal watersheds at the Hakai watersheds observatory on Calvert and Hecate Islands, British Columbia Central Coast.
Brief summary of methods
For detailed information on sample collection and methods of analysis please refer to Oliver et al. 2017.
Stream water grab samples were collected every 2-3 weeks (or ~monthly in winter) from May 2013 to July 2016 (n= 402) from stream outlets of the seven focal watersheds monitored within the Kwakshua Channel watersheds. Samples were run for analysis of dissolved organic carbon (DOC), iron (Fe), and optical characterization of dissolved organic matter (DOM) using spectrofluorometry. Excitation emission matrices (EEMs) were used in parallel factor modeling (PARAFAC) to deconstruct and identify individual fluorophore components of DOM.  Model output from this PARAFAC analysis can be found online at www.openfluor.org. 
Stream discharge was measured by developing stage discharge rating curves at a fixed hydrometric station in proximity to the outlet. DOC flux was estimated using multiple regression methods in the R package rloadest by combining DOC concentrations with 15-minute continuous stream discharge from each watershed. Loads for October 1, 2015 through April 30, 2016 are presented for each watershed in average kilograms per day. Further details on the development and analysis of stage discharge rating curves and multiple regression models used for estimating DOC flux can be found in Oliver et al. 2017

Mobile Invertebrate Rocky Intertidal Surveys - BC Central Coast - 2016-2018

Keywords: None
Temporal coverage: None

The mobile invertebrate community associated with three primary habitat types (mussels, barnacle and Fucus distichus) was assessed from 2016-2018 at three coastal sites along the northwest edge of Calvert Island on the central coast of British Columbia. All sites were exposed rocky shorelines with distinct zones of mussels, barnacles, and Fucus distichus algae. We surveyed the abundance and diversity of the mobile invertebrate community within permanent plots in each zone. Counts were performed using the point intercept method with a strung quadrat and size was measured for a subset of species. Plots were also subsampled using smaller unstrung quadrats, within which smaller limpets and littorine snails were counted. The Sites were surveyed on an approximately monthly basis from May-September, and two winter surveys in November and February. We conducted 6 surveys in 2018, 5 in 2017, and 3 in 2016.
