Environmental data for an ordination analysis explaining the abundance of MAST-1 sub-clades

The datasets present new data from microscopic counts and selected nutrient and physical data assembled from the following missions. Aboard the CCGS Louis St-Laurent: IPY Canada's Three Oceans 2007. Aboard the CCGS Amundsen: International Polar Year (IPY) Circumpolar Flaw Lead Study 2008; ArcticNet 2008. Temporal coverage is July-September. Cell density of the three sub-clades MAST-1A, MAST-1B and MAST-1C was measured by cell-counts using fluorescent in situ hybridization with taxa-specific probe. Biomass of phototrophic organisms, of different size classes, was obtained by counts of DAPI-stained cells under epifluorescence microscopy. Samples for total chlorophyll a (chl a) were filtered onto GF/F filters, extracted in either ethanol or acetone and analysed by spectrofluorometry. Chl a was also measured for the < 3 µm size fraction, and chl a in the < 3 µm size fraction was calculate by simple substraction. CCGS Amundsen data: Temperature, salinity, transmissivity, oxygen, and photosynthetically active radiation were provided by Dr. Y. Gratton (Institut National de la Recherche Scientifique, Québec). Nitrate and Phosphate concentrations were provided by Dr. J.-É. Tremblay (Université Laval, Québec). CCGS Louis St-Laurent data were supplied by Drs. E.C. Carmack and J. Nelson (Institute of Ocean Sciences, Sidney, B.C.). Distance to ice edge was obtained from the Canadian Ice Services (http://ice-glaces.ec.gc.ca).

Stomach content of 339 age-0 Arctic cod collected in the Canadian Arctic between 2009 and 2018.

Age-0 Arctic cods (Boreogadus saida) were collected in 8 regions of the Canadian Arctic between August 5th 2009 and August 28th 2018, onboard CCGS Amundsen using both oblique (Tucker Net) and vertical tows (Monster Net). Onboard, age-0 fish (larvae and juveniles) were sorted from the macrozooplankton sample, identified to the lowest taxonomic level possible, measured fresh (standard length, SL), and preserved in 95% ethanol. The digestive tracts of 339 Arctic cods were dissected under binocular in glycerol and individual prey were identified to the lowest taxonomic level possible and measured. The carbon content of each individual prey was inferred from species-specific length to carbon equations from the primary literature (see Bouchard et al. 2016 for the equations).

Production, biomass, abundance and taxonomic composition of phytoplankton in Labrador Sea, Davis Strait, Baffin Bay, Canadian Arctic Archipelago and Beaufort sea during the summer and fall 2016

Phytoplankton composition and abundance were investigated from Labrador Sea up to Kennedy Channel, in Frobisher Bay, in the Canadian Arctic Archipelago (Lancaster Sound, Barrow strait, Franklin strait, Victoria Strait, Queen Maud Gulf), as well as in Beaufort Sea and in Amundsen Gulf from 14 July to 06 October 2016. Sampling was carried out with a CTD-rosette system. Water samples were collected at 7 optical depths (100, 50, 30, 15, 5, 1 and 0.2% of surface irradiance) determined with a Secchi disk and a PNF-300, at the depth of the  maximum chlorophyll fluorescence, and at 2 depths in the aphotic zone (generally 75m and 100m). Incident PAR was measured continuously during the cruise with a LI-COR PAR sensor. Water samples were collected for the determination of size-fractionated chlorophyll a and pheopigments (>0.7 um; >5 um; >20 um], total and dissolved organic carbon and nitrogen (TOC/DOC/DN), total particulate carbon and nitrogen (TPC/TPN), phytoplankton identification, pico-, nanophytoplankton and heterotrophic bacteria abundance, as well as pigment signature by HPLC. Note that most of these variables were not measured at all depths. Size-fractionated primary production (>0.7 um; >5 um) was measured at the 7 optical depths including the depth of the maximum chlorophyll fluorescence using the 14C-method (JGOFS protocol) with on-deck in situ simulated incubations.

Dimethyl sulfide and its oxidation products during the Arctic fall (2007 and 2008)

Atmospheric DMS was adsorbed on tenax columns and desorbed onto a Hewlett
Packard 5890 gas chromatograph (GC) fitted with a Sievers Model 355 sulfur chemiluminescence detector (SCD) detection system on board the Amundsen.  Atmospheric DMS samples were collected en route to the North Water Polyna and as the ship moved in ice-free and ice-pack conditions.  Daily shipboard sulphur dioxide and size-segregated cascade impactor aerosol sulphate and methane sulfonic acid (MSA) samples were collected using filters fitted to high volume samplers on board the Amundsen. High volume samplers were operated continuously. The contribution of gases and aerosols from ship stack emissions was determined using CO2 Li-Cor measurements with an air inlet in the vicinity of the high volume samplers.  Corresponding size segregated aerosol samples were collected at Alert using high volume samplers for the duration of the ship study.  Filter samples from the high volume samplers returned to the Isotope Science Laboratory in Calgary will be analyzed for ion chemistry and S and O isotope analyses (IC for anions, ICP-MS for cations, EA-IRMS for S and O isotope analyses) to define the contribution of SO2 and aerosol sulphate from DMS oxidation.

Annapolis County Wave Data

The Centre for Marine Applied Research (CMAR) provides high resolution data on ocean variables from around the coast of Nova Scotia through their Coastal Monitoring Program. The program was initiated by the Nova Scotia Department of Fisheries and Aquaculture (NSDFA) in 2015. In 2019, CMAR assumed responsibility for the program and expanded its scope and mandate. Through the Wave Branch of the program, CMAR processes and publishes Wave data collected by NSDFA. The data are measured by upward facing Acoustic Doppler Current Profilers (ADCPs) that are mounted on the sea floor for 1 - 3 months. An ADCP uses sound to measure wave variables including height, period, and direction. NSDFA uses several ADCP instrument models, including the Sentinel V20, Sentinel V50, Sentinel V100, and Workhorse Sentinel 600kHz. The data is processed using Velocity and WavesMon4 Software, and then compiled and formatted for publication with CMAR’s waves R package. An automated “Gross Range” test was applied to the data to identify statistical outliers. Each data point was assigned a flag value of “Pass”, “Suspect/Of Interest”, or “Fail”. Observations flagged as “Pass” passed the test (i.e., were not considered outliers) and can be included in analyses. Observations flagged as “Fail” were considered outliers and should be excluded from most analyses. Observations flagged as “Suspect/Of Interest” were either poor quality or highlight an unusual event, and should be carefully reviewed before being included in analyses. Flags should be used as a guide only, and data users are responsible for evaluating the quality of the data prior to use in any analysis.  The ''Nova Scotia Current and Wave Data: Deployment Information'' dataset on this Portal shows all locations with available Wave data collected through CMAR’s Coastal Monitoring Program (https://data.novascotia.ca/Fishing-and-Aquaculture/Nova-Scotia-Current-and-Wave-Data-Deployment-Infor/uban-q9i2/about_data). Summary reports for each county are available on the CMAR website (https://cmar.ca/coastal-monitoring-program/). Data collection and retrieval are ongoing. The datasets and reports may be revised pending ongoing data collection and analyses.  If you have accessed any Coastal Monitoring Program data, CMAR would appreciate your anonymous feedback: https://docs.google.com/forms/d/e/1FAIpQLSe3TD6umrsVVKnQL13VVMJIpckCi2ctONJsgN7_g-4c-tKTuw/viewform.

Intertidal Temperature from Coastal Nova Scotia

Intertidal habitats are unique because they spend alternating periods of submergence (at high tide) and emergence (at low tide) every day. Thus, intertidal temperature is mainly driven by sea surface temperature (SST) during high tides and by air temperature during low tides. Because of that, the switch from high to low tides and viceversa can determine rapid changes in intertidal thermal conditions. On cold-temperate shores, which are characterized by cold winters and warm summers, intertidal thermal conditions can also change considerably with seasons. Despite this uniqueness, knowledge on intertidal temperature dynamics is more limited than for open seas. This is especially true for wave-exposed intertidal habitats, which, in addition to the unique properties described above, are also characterized by wave splash being able to moderate intertidal thermal extremes during low tides. To address this knowledge gap, we measured temperature every half hour during a period of 5.5 years (2014-2019) at nine wave-exposed rocky intertidal locations along the Atlantic coast of Nova Scotia, Canada. This data set is freely available from the figshare online repository (Scrosati and Ellrich, 2020a; https://doi.org/10.6084/m9.figshare.12462065.v1). We summarize the main properties of this data set by focusing on location-wise values of daily maximum and minimum temperature and daily SST, which we make freely available as a separate data set in figshare (Scrosati et al., 2020; https://doi.org/10.6084/m9.figshare.12453374.v1). Overall, this cold-temperate coast exhibited a wide annual SST range, from a lowest overall value of -1.8 °C in winter to a highest overall value of 22.8 °C in summer. In addition, the latitudinal SST trend along this coast experienced a reversal from winter (when SST increased southwards) to summer (when SST decreased southwards), seemingly driven by alongshore differences in summer coastal upwelling. Daily temperature maxima and minima were more extreme, as expected from their occurrence during low tides, ranging from a lowest overall value of -16.3 °C in winter to a highest overall value of 41.2 °C in summer. Daily maximum temperature in summer varied little along the coast, while daily minimum temperature in winter increased southwards. This data set is the first of its kind for the Atlantic Canadian coast and exemplifies in detail how intertidal temperature varies in wave-exposed environments on a cold-temperate coast.
