Hakai Institute Juvenile Salmon Program Time Series

Keywords: None
Temporal coverage: 2015-05-12T00:00:00

The Hakai Institute Juvenile Salmon program is an ongoing initiative that was established in 2015 in partnership with the University of British Columbia, University of Toronto, Simon Fraser University and Salmon Coast Field Station. This program researches the early life history of juvenile salmon in coastal British Columbia. Primary research objectives are determining: 
1) Migration timing rates and routes; 
2) Migration habitat, including physical and chemical oceanographic conditions, and availability of plankton prey; 
3) The impacts of prey phenology, quantity and quality on juvenile salmon growth and condition; 
4) Species and stock-specific feeding biology and competitive interactions; 
5) Pathogen and parasite infection dynamics; and 
6) Mortality estimates. 

The program targets Fraser River sockeye, and pink and chum salmon, but additionally provides information on coho, chinook, and herring through incidental capture. The field program operates between May and July during the peak of the juvenile sockeye outward migration. Purse seine and oceanographic sampling are conducted in the northern Strait of Georgia / Discovery Islands region (~ 220 km from the Fraser River mouth) and the Johnstone Strait / Queen Charlotte Strait region (~ 180 km from the northern Strait of Georgia. As such, this program informs early life history across two critical legs of the Fraser salmon northward migration.

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

Keywords: None
Temporal coverage: None

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.
Eelgrass (Z. marina) extent within the greater park ecosystem of Pacific Rim National Park Reserve eelgrass monitoring sites (2017, 2018) v1.0.0

Keywords: None
Temporal coverage: None

This data package contains reports and datasets pertaining to mapping the spatial extent of eelgrass (Zostera marina) at several monitoring sites within the greater park ecosystem of Pacific Rim National Park Reserve located on the west coast of Vancouver Island, British Columbia, Canada. This work was a collaborative project between the Hakai Institute and the Pacific Rim National Park Reserve (PRNPR).  

Monitoring sites were mapped using a small Remotely Piloted Aerial Systems (RPAS) (DJI Phantom Pro 3) during summer low tides in 2017 and 2018. Orthomosaics of each site were created using a Structure from Motion Multi-View Stereo (SfM-MVS) workflow within Pix4Dmapper software (Version 2.1.61, Pix4D) in Windows 10. For the 2017 survey, ground control points were collected for georeferencing the orthomosaics. This was not done in 2018 due to time limitations (please see reports for more details). 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:

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

Keywords: None
Temporal coverage: 2017-05-20/2017-07-19

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.

Macrocystis kelp canopy productivity data from BC Central Coast, v1.3.0

Keywords: None
Temporal coverage: 2014-05-01T00:00:00

The macrocystis canopy productivity dataset is a component of the Hakai Institute Nearshore research and monitoring program. This dataset documents seasonal and annual changes in Macrocystis pyrifera biomass, density, productivity and reproduction on the Central Coast of British Columbia during the primary growing season (April to October). Density and morphometric measurements of kelps in situ were quantified within three to five permanent monitoring sites to determine kelp size structure, growth rates and loss rates throughout the growing season (2014-2018). Additional sites are visited annually (ongoing since 2014) to estimate annual change in biomass at these locations. Outcomes of this research show that biomass and productivity of M. pyrifera varies spatially and temporally. Based on these data we can determine which field parameters best correlate with overall M. pyrifera productivity and biomass, and ultimately, refine metrics for long-term assessments of this canopy kelp status on BC’s coast and find what environment drivers are most important to its density, spread and health.
