Surface water CO2 parameters collected by Alaskan citizens around the northern Gulf of Alaska from April 2015 to August 2017

Hakai Institute
pCO2 and TCO2 measurements were made on surface seawater collected by tribal citizens and non-oceanographic agencies around Kenai Peninsula in the northern Gulf of Alaska from 2015 to 2017. Seawater was collected using bucket grabs or Niskin bottles and drawn into 350 mL amber glass bottles. Sample bottles were rinsed 3 times and then carefully filled with sample seawater as to not introduce bubbles into the sample. Sample temperature was then recorded using NIST traceable...

Bathymetry for Six Lakes on Calvert and Hecate Islands, BC

Hakai Institute
Bathymetric surveys were completed for six lakes on Calvert and Hecate Islands as part of the Kwakshua Watersheds Program. The surveys were conducted at different times from May to July 2016 using a canoe-mounted, location-aware depth sounder and by taking random manual depth measurements. All depth recordings are referenced to a survey benchmark and have been quality controlled, cleaned and processed in a 3D GIS environment. For each lake, bathymetry has been modeled by means...

High-resolution record of surface water pH at Sentry Shoal in the Northern Strait of Georgia

Hakai Institute
The northern Strait of Georgia (nSoG) in British Columbia, Canada is part of the large inland Salish Sea and has sparse carbonate system data coverage relative to the inter-seasonal and regional variability. The Environment Canada weather buoy at Sentry Shoal in the nSoG provides a platform of opportunity for collection of high frequency carbonate system measurements. During summer and fall of 2016 and 2017, autonomous sensors were deployed at the surface to measure in situ...

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

Maartje C. Korver
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...

Uncertainty analysis of stage-discharge rating curves for seven rivers at Calvert Island

Maartje C. Korver
Knowledge of freshwater runoff is an essential component for estimating terrestrial material fluxes into coastal areas. Discharge estimates are often based on a direct relation between the stage height at a particular gauging station and discharge (rating curve), in combination with continuous stage monitoring. The aim of this study was to develop rating curves for seven watersheds in the bog forest environment of Calvert Island, British Columbia, Canada and to investigate the uncertainties related to...

Seascape connectivity data from a sub-tidal Zostera marina meadow, Choked Passage, Calvert Island, 2015

Hakai Institute
This dataset was used to determine how seascape connectivity alters the nursery function of seagrass (Zostera marina) meadows for young-of-the-year (YOY) rockfish. Here, the influence of seascape connectivity was assessed via the configuration and composition of adjacent habitats (kelp forests, sand), as well as allochthonous subsidies entering the seagrass food web. Data was collected in an extensive, sub-tidal Z. marina meadow in Choked Passage, on the Central Coast of British Columbia (51.675 °N, -128.119 °W)...

Katie Pocock, Wiley Evans, Alex Hare & Burk Hales
The Burke-o-Lator (BoL) pCO2/TCO2 analyzer measures carbon dioxide partial pressure (pCO2) and total dissolved inorganic carbon (TCO2) both continuously from a flow-through seawater stream and from seawater collected in discrete samples. The Hakai Institute operates BoL units at shore-side facilities along the Pacific coast in Alaska and British Columbia, and our discrete sample analyses of seawater marine carbonate system parameters are conducted using this instrumentation. This protocol is intended for BoL users that are familiar...

Stage-Discharge Time Series - Calvert Island - Archived Version 2.0

Hakai Institute
Streamflow calculation; a component of the Kwakshua Watersheds Program In natural streams it is not possible to continuously measure stream discharge, thus an indirect approach was used, where river height (stage) was continuously measured at a gauging station using a pressure transducer, with periodic manual measurements of discharge along the range of potential stages to develop a stage-discharge rating curve. Low flows were manually measured using the velocity-area method, with either a Swoffer Current Velocimeter...
