Spatial extent of eelgrass (Zostera marina) meadows from monitoring sites within Gwaii Haanas (2016, 2017, 2018) mapped using remote piloted aerial systems

This data package contains reports and datasets pertaining to mapping the spatial extent of eelgrass (Zostera marina) at monitoring sites within Gwaii Haanas National Park Reserve, National Marine Conservation Area Reserve, and Haida Heritage Site, located in Haida Gwaii, British Columbia, Canada. This work was a collaborative project between the Hakai Institute and Gwaii Haanas Parks Canada.  

Monitoring sites were mapped using small Remotely Piloted Aerial Systems (RPAS) (DJI Phantom Pro 3, Pro 4) during summer low tides in 2016, 2017 and 2018. Orthomosaics were created using a Structure from Motion Multi-View Stereo (SfM-MVS) workflow within Pix4Dmapper software (Version 2.1.61, Pix4D) in Windows 10 and georeferenced using group control points collected concurrently during the surveys. The extent of eelgrass at each site was delineated using object-based image analysis (OBIA) with eCognition Developer software (eCognition Developer 9, 2014) and manual delineation (where necessary). Georeferenced towed underwater video (SplashCam Pro) data were collected at eelgrass monitoring sites during high tide to provide ground-truth data for the aerial analysis and delineation of eelgrass. 

The data package includes:

- The reports (.pdf) which describe project, data collection and processing methods and results for 2016,  2017 and 2018 surveys. 
- Polygon shapefiles (.shp) of the extent of eelgrass (Z. marina) at each monitoring site by year.
- Point shapefiles (.shp) of classified towed underwater video transects by year. 

Coordinate system used: NAD1983 UTM Zone 9N

These data were collected as an ongoing partnership between Gwaii Haanas Parks Canada and the Hakai Institute. This data package is a component of the Hakai Institute’s Habitat Mapping program. The overarching objective of the Hakai Habitat Mapping program is to generate spatial inventories of coastal habitats, investigate how these habitats are changing through time, and the drivers of that change. This data package is also a component of the National Marine Conservation Area ecological sustainability monitoring program of Parks Canada. The overarching goal of the program is to track changes in marine ecosystems, respond to environmental threats, and ensure ecologically sustainable use of marine resources.

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

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 .

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.

High-resolution record of surface seawater CO2 content from November 2017 to June 2018 collected in Hyacinthe Bay, British Columbia, Canada

Quadra Island, at the northern terminus of the Salish Sea, has been a site for shore-based and high-resolution measurement of surface seawater CO2 content since December 2014. Measurements of in situ temperature, salinity, and CO2 partial pressure are made near-continuously from a seawater sample line with an intake 50 m from shore and at a depth of 1 m in Hyacinthe Bay on the eastern side of Quadra Island. The effort to collect these data are part of the Hakai Instituteâ€™s directive to advance the understanding of carbon cycling in northeast Pacific coastal settings with specific emphasis on sea-air CO2 exchange and ocean acidification. This data contribution consists of measurements from November 9, 2017 to June 1, 2018.

Kelp forest communities along an otter gradient

Despite their profound and prolonged ecological and societal consequences, regime shifts are notoriously difficult to anticipate. For example, in kelp forest ecosystems the cascading effects of sea otters are well known to trigger shifts between forested and deforested rocky reefs, however forecasting when and where these shifts will occur a priori remains a key challenge because previous studies tend to use binary or categorical levels of otter presence. To illuminate this knowledge gap, we sampled benthic reef communities at 20 sites along a continuous gradient in sea otter occupation time (0-33 years) along the central coast of British Columbia, Canada where otters are recovering after over a century of local extinction. This dataset contains diversity, size, and abundance data on benthic invertebrate and fish species and abundance and diversity data on kelp species along a gradient of otter occupation. Because of the regression style sampling protocols, this dataset can be used to characterize tipping points between kelp forest vs. urchin barren states along the Central Coast of BC.

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

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.

ESRF - Atlantic Salmon Offshore Tracking Project - Ocean Drifters

This collaborative research project will use acoustic and satellite telemetry to determine when, where and for how long Atlantic salmon from three different life stages (post-smolt, kelts returning to sea to recondition, and multi-sea winter adults) are in the Eastern Canadian offshore regions (Environmental Studies Research Fund [ESRF] Regions 8 to 15) of interest for oil and gas development to inform regulatory decision-making and future project development. This research project has been developed and is being implemented collaboratively with First Nations and partners from academia, the NGO sector, government and the public. The project is led by the Department of Fisheries and Oceans (Martha Robertson, Principal Investigator). Results will contribute significantly to our currently limited understanding of how Atlantic salmon use the marine areas off Eastern Canada and support evidence-based decision making and co-development of best operational practices to minimize potential adverse impacts of oil and gas activities on Atlantic salmon.
