Surfgrass Communities - Motile Invertebrate Surveys - BC Central Coast - 2018-2019

Keywords: None
Temporal coverage: None

The surfgrass motile invertebrate 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 motile invertebrate community was assessed at three coastal sites along the northwest edge of Calvert Island on the central coast of British Columbia, beginning in 2018. All sites were exposed rocky shorelines with beds of Surfgrass (Phyllospadix spp) growing in the low intertidal. The abundance and diversity of the motile invertebrate community was surveyed in these beds using transects and quadrats. The placement and length of the transect was replicated through time, quadrat placement was not. Counts or percent cover were recorded for mobile invertebrates within quadrats placed along a surfgrass bed transect .

Nearshore Macrophyte Stable Isotopes - BC Central Coast - 2014-2018

Keywords: None
Temporal coverage: None

The macrophyte stable isotope dataset is a component of the Hakai Institute’s Nearshore research
and monitoring program. 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. Macrophyte tissue samples were collected from five
major nearshore habitats over the years 2014 - 2018. Samples were collected from sites on or in the
near vicinity of northern Calvert Island on the central coast of BC. Collection sites varied significantly
in character both among and within habitats. At each site, the dominant macrophyte species were
targeted for collection. As a result, a variety of species, from algae and seagrasses, are found within
this dataset and vary slightly in sampling methods between habitats. The tissue samples were dried,
processed, and analyzed for natural abundances of 13 C and 15 N.

Water column carbonate system measurements from the Pacific Salmon Foundation Citizen Science Program stations from July 2016 to October 2017 in the northern Salish Sea, British Columbia, Canada

Keywords: None
Temporal coverage: None

pCO2 and TCO2 measurements were made on seawater collected from 2 depths at up to 10 stations from the Baynes Sound, Lund and Powell River patrols of the Pacific Salmon Foundation’s Citizen Science Program, approximately every 2 to 3 weeks from July 2016 to October 2016 and from March 2017 to October 2017. Seawater was collected in General Oceanics niskin bottles at 0 and 20 m depths using a calibrated line meter on the sampling vessel. Seawater temperature was determined at the time of sample collection with NIST-traceable thermometers (VWR PN 23609-176). Seawater samples were preserved with mercuric chloride immediately upon sample collection. Laboratory temperature and seawater salinity were determined at the time of sample analysis at the Quadra Island Field Station (QIFS) using NIST traceable thermometers and a YSI MultiLab 4010-1 with a MultiLab IDS 4310 conductivity and temperature probe. The YSI probe was calibrated using certified reference materials of known salinity prior to seawater sample analysis. For detailed protocols on sample collection, data processing including CO2 system determination, and quality assurance, please see Pocock et al. (2017; http://dx.doi.org/10.21966/1.521066). Note alkalinity (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.
Nereocystis kelp canopy productivity data from BC Central Coast, v1.2.0

Keywords: None
Temporal coverage: 2016-05-01T00:00:00

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.
