Halifax County Water Quality Data

The Centre for Marine Applied Research (CMAR) provides high resolution ocean data from around the coast of Nova Scotia through their Coastal Monitoring Program. Through the Water Quality Branch of the program, CMAR collects temperature, dissolved oxygen, and salinity data using sensors deployed on stationary moorings. A typical mooring consists of a line anchored to the sea floor and suspended by a sub-surface buoy, with sensors attached at various depths. Alternatively, sensors may be attached to structures including buoys, docks, or aquaculture equipment. Sensors are deployed for several months, and data are measured every 1 minute to 1 hour. Station locations, summary reports, and data collection methods are available on the CMAR website (https://cmar.ca/coastal-monitoring-program/). Datasets and reports may be revised pending ongoing data collection and analyses. Automated Quality Control tests were applied to the data to identify outlying and unexpected observations. The results of these tests are summarized in the “qc_flag” columns of the dataset. Observations flagged as “Pass” passed all tests, while observations flagged as “Fail” failed at least one test and should be excluded from most analyses. “Suspect/Of Interest” flags highlight unusual events or poor quality data, and “Not Evaluated” flags indicate at least one test was not applied to the observation. Flags should be used as a guide only, and users are responsible for evaluating the data quality prior to use. For technical details on the Quality Control tests, visit the CMAR Data Governance website (https://dempsey-cmar.github.io/cmp-data-governance/pages/cmp_about.html). Other data quality considerations:  -	Through calibration-validation procedures, CMAR has discovered that the VR2AR temperature sensors typically record 0.5 – 1 °C lower than other temperature sensors. This is not corrected for or flagged in the datasets but may be in the future. -	Sensor drift is not flagged in the datasets. -	The sensor_depth_at_low_tide_m is an estimate and should be compared to sensor_depth_measured_m when possible. Note the mooring can get “knocked down” by currents or sink from biofouling. Large discrepancies between the estimated depth and the minimum recorded depth are flagged in the column depth_crosscheck_flag. The Coastal Monitoring Program Water Quality data is organized by county. These datasets are very large, typically exceeding the number of rows that can be viewed in Excel. CMAR recommends filtering the data to the waterbody, station, depth, quality control flag, and/or time period of interest before exporting. Take care when exporting data filtered on quality control columns, because the whole row will be filtered (i.e., all other variables measured at that timestamp will also be excluded).

Fish samples in the Labrador Sea and Canadian Arctic (2017-2024)

The dataset is composed of adult fish species captured during the ArcticNet cruise aboard the CCGS Amundsen from 2017 to 2024. Pelagic fish were caught with an Isaacs-Kidd Midwater Trawl (IKMT, 9-m2 rectangular mouth aperture with mesh sizes of 11 mm in the first section and 5 mm in the last section). It was deployed from the surface to depths targeting possible aggregation of fish as recorded by the acoustic echosounder from the ship. Demersal and benthic fish were sampled with a bottom beam trawl (3-m2 rectangular aperture with a headline and a footrope of 4.27 m and a cod-end mesh of 9.5 mm) deployed on the seafloor. The pelagic and bottom trawls were towed at ~3 knots for 10 to 20 min. All fish collected by the trawls were measured and identified at least to the family level before freezing at -20°C. Note: No data was collected from the Arctic during 2020 since there was restricted access due to the COVID-19 pandemic.

LAser WAve Slope (LAWAS) laser profiling data

The laser profiling instrument is mounted on the front deck of the Amundsen icebreaker on the port side. The instrument has four lasers that emit laser radiation of 900nm at regular intervals. The LAWAS profiler has been used during the transit to acquire data over various types of ice and surfaces. The data is a binary data file which can be read using a code. The profiler also has a motion pack which measures the acceleration in  x, y and z direction.  Five files are created from each observation, four files from each of four lasers and one file from motion pack.

Snow and Ice Physical Properties

General description: Ice types from new ice up to thick first-year sea ice (FYI) were encountered, with one case of multiyear ice (MYI) examined.
Methology: The sampling can be divided into "Transect Mode" and "Drift Mode." For the transect mode, we accessed the ice surface using the ice cage lowered from the deck at the port side. For the drift mode, we accessed the ice surface twice daily using the gangplank.
Collected variables in the snow and/or frost flowers were: 1) Temperature profile (Traceable® Digital Thermometer, Control Company), 2) Stratified samples for salinity, 3) Snow grain samples (photographically analyzed in the cold lab on the ship), 4) Density (derived by using a known volume physical sample and measuring the weight on the ship), 5) Derived liquid water content (measured using a capacitance plate technique). 
Collected variables in the ice were: 1) Thickness, 2) Freeboard, 3) Temperature profile, 4) Salinity profile, 5) Microstructural analysis (including vertical for the complete core and horizontal sections in the top layers of drift stations).

Optical properties and carbon fluxes of the Eastern Canadian Arctic Ocean

Apparent and inherent optical properties (AOPs and IOPs), stock measurement of seawater samples and particles and fauna distribution profiles with an Underwater Visio Profiler (UVP) were studied from July 8 to August 14 (Leg 1) mainly in the Labrador Sea, Baffin Bay and Lancaster Sound. Some measurements were made further North in the Nares Strait and the Kennedy Channel. As the UVP was integrated in the CTD/rosette system of the Amundsen, it was deployed through out the expedition until September 25th in Beaufort and Chuckchi Seas.
For the IOPs, 27 stations were sampled during Leg 1. IOPs profiles were measured using 2 optical packages, which include the following sensors: backscattering meters (from HobiLabs Hydroscat-6), fluorometers for colored dissolved organic matter absorption (CDOM) and chlorophyll. AOPs profiles were measured using a Compact-Optical Profiling System with 15 wavelengths (Biospherical). As for above-water radiometry, multispectral incident downwelling irradiance (Ed0+ at 15 wavelengths) was measured continuously from the top bridge using an irradiance meter (Biospherical) mounted on a 5-m telescoping mast. A sunphotometer was also used to derive the aerosol optical thickness and ozone concentration.
Seawater samples were collected at the surface and maximum chlorophyll fluorescence using the CTD-rosette system. Surface seawater was also collected from the barge and a bucket. Particulate absorption, CDOM, pigment concentrations (HPLC) and particulate organic carbon and nitrogen content samples were collected at 24, 21 and 19 stations respectively. All water samples were stored frozen. The analyses were achieved in laboratories at Laval University and the University of Québec at Rimouski. Particulate absorption was measured following Rottgers & Gehnke (2012) method using a Perkin-Elmer lambda 850 spectrophotometer, CDOM was measured using a variable pathlength spectrophotometer (Ultrapath), pigment were analyzed following Zapata et al. (2000) method and POC-PON were analyzed using a CHNS/O elementary analyzer.
The UVP enables identification and enumeration of zooplancton species and of sediment with size up to 200 µm. The open source software provided with the instrument is dedicated to the study of big particles (>100 µm) and study of zooplankton (mesozooplancton and micronecton). Pictures processing is achieved in a delayed mode.   The UVP was deployed systematically at each CTD cast but for leg1a where it was under repair.
