This dataset includes discrete sample and profile data collected during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) F/V Frosti cruise 18DN190802 (EXPOCODE 18DN20190802) in the Arctic Ocean, Beaufort Sea from 2019-08-02 to 2019-09-09. These data include water temperature, salinity, dissolved oxygen, dissolved inorganic carbon (DIC) and total alkalinity. Starting in 2017, Fisheries and Oceans Canada (DFO) conducted a survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope in August and early September each year. Sampling was conducted from the F/V Frosti at 144 stations along nine multi-year transects; and 32 non-transect stations. Standardized sampling was conducted at pre-determined depth stations using a variety of sampling equipment including benthic fishing trawls; plankton nets; sediment cores; and CTD and water sample profiles. The ocean acidification program was implemented in DFO’s Central and Arctic Region (Freshwater Institute) in 2017, funded by the Aquatic Climate Change Adaption Services Program (ACCASP). This submission covers measurements conducted in the Canadian Beaufort Sea in 2019.

Supplemental Information
In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number.
Purpose The Canadian Beaufort Sea-Marine Ecosystem Assessment (CBS-MEA) continues to build on existing baseline data and ecological knowledge derived from the Beaufort Regional Environmental Assessment-Marine Fishes Project. The CBS-MEA focuses on integrating oceanography; food web linkages; physical-biological couplings and spatial and inter-annual variability; while also expanding data on species diversity; abundances; and habitat associations.

On percent of water volume was removed to allow room for thermal expansion and the sample was preserved within 30 minutes of collection with 50 uL of a mercuric chloride saturated solution; then sealed with Apiezon M grease and the ground glass stoppers secured in place with rubber bands. The samples were stored at room temperature until on-shore laboratory analysis. The samples were analysed for DIC using a SOMMA sample handling system in conjunction with a coulometer (UIC Inc.) to quantify total CO2 purged from the acidified sample.

  • Parameter or Variable: Total alkalinity; Abbreviation: ALKALI; Unit: UMOL/KG; Observation type: discrete; Measured or calculated: measured; Calculation method and parameters: Concentration (umol / kg) = concentration (umoles/litre) / density (10 C;S); Sampling instrument: CTD and rosette bottle sampler: Niskin bottle; 10-12 L; Analyzing instrument: In-house automated sampler with Metrohm Titrando dosimat and Tiamo software; Type of titration: Potentiometric multi point titration; Cell type (open or closed): Open; Curve fitting method: Gran point; Detailed sampling and analyzing information: Seawater samples were collected from standard depths in 250 mL borosilicate glass reagent bottles. Five mL of water was removed to allow room for thermal expansion and the sample was preserved within 30 minutes of collection with 50 uL of a mercuric chloride saturated solution; then sealed with Apiezon M grease and the ground glass stoppers secured in place with rubber bands. The samples were stored at room temperature until on-shore laboratory analysis. TA in the sample was determined using an open cell automated potentiometric titration with a Metrohm Titrando dosing unit controlled by Metrohm Tiamo software. The multi-point titration; using 0.1N HCl titrant containing 35 g of sodium chloride per litre of acid; was performed in a temperature controlled flask held at 25 ¬∞C with Gran endpoint determination.
