CFL 0805 - Beaufort Sea CTD data

Summary:
The CTD data was obtained during the 2007-2008 scientific cruise #0805 within the framework of the Circumpolar Flaw Lead Study (CFL). This program included a year round sampling expedition to study the air-sea interactions occurring in the ice-free sections of the southern Beaufort Sea and Amundsen Gulf.

The data were collected from July 19 to August 5, 2008, aboard the CCGS Amundsen. There were 64 CTD casts, associated to 47 stations, located in the Beaufort Sea research area.

The following parameters were measured: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), dissolved oxygen (Sea-Bird SBE-43), pH (Sea-Bird SBE-18-I), fluorescence (Seapoint chlorophyll fluorometer), nitrate concentration (Satlantic MBARI-ISUS 5T), transmittance (Wetlabs C-Star transmissometer), light intensity (PAR; Biospherical Instruments QCP2300) and surface light intensity (sPAR; Biospherical Instruments QCP2200). Quality control procedures were applied to the data. Data are available on the Polar Data Catalogue and at the Marine Environmental Data Service (MEDS) of Fisheries and Oceans Canada.

CTD data collected by the CCGS Amundsen in the Canadian Arctic

Summary:
CTD data are obtained during the annual CCGS Amundsen scientific expeditions in the Canadian Arctic regions.
A large number of CTD rosette casts are performed every year. The rosette has twenty four sampling water bottles and several instruments attached to its frame to collect water samples and records physical and chemical data (temperature, conductivity, pressure, fluorescence, light transmission, nitrate, photosynthesis) with sensors. The water samples are distributed to the scientific teams for in-situ analysis. In-situ data belong to and are under the responsibility of the leading scientists while physical and chemical data from the sensors are part of the Amundsen core data collection.
Data typically measured each year and provided in this archive are as follows: temperature, conductivity and pressure (with a Sea-Bird SBE-9plus), dissolved oxygen (Sea-Bird SBE-43), fluorescence (Seapoint chlorophyll fluorometer), CDOM (Wetlabs FL(RT)D), nitrate concentration (Satlantic MBARI-ISUS 5T), transmittance (Wetlabs C-Star transmissometer), light intensity (PAR; LI-COR Biosciences) and surface light intensity (sPAR; LI-COR Biosciences).
Quality control procedures are applied to the data which are available under these formats: .int (one cast by file), .odv, .kml, .btl and .odf (on demand).
Since 2024, data profiles from a second Rosette located in the ship moon pool have been added to the contents of this dataset archives. Specifically, that Rosette does have special bottle for water contaminants sampling. Data from the second Rosette are flagged as TM (Trace Metal) in the related archive folder and those from the usual Rosette flagged as "classic".

High Biodiversity (HiBio) Mooring Data Collection.

Summary:
This dataset contains data collection from High Arctic Biodiversity (HiBio) program for the years 2017, 2019, 2020, and 2021. They were collected in Hatton Bassin at the Labrador Sea with installed fixed moorings (HiBioA, HiBioC, MkB1). Mooring reports are included within the archive as well. The data were retrieved from the moorings each year. The HiBioA mooring was equipped with profiling current meters (Seaguard CTD-Tu-DO), sediment traps and hydrophones (model: JASCO AMAR G3). The hydrophone listens for marine mammal activity by recording bioacoustics vocalizations throughout the year on the shelf-slope area. The HiBioC was equipped with an RBR Concerto-CTD-Tu, which measures sea water Conductivity, Temperature and Depth. Other parameters such as sea water Salinity and turbidity are also included in this dataset. The data processing chain is built upon open-source Integrated Marine Observatory System (IMOS) toolbox developed for Matlab© by the Australian Ocean Data Network (AODN; Galibert, 2016). Additional Quality Control (QC) procedure is applied to the ArcticNet-specific mooring data. These are described in the technical report of the data processing. The data are stored in Network Common Data Form (NetCDF) format following the international standard Climate Forecast (CF) convention.

Hydrobios-CTD data collected by the CCGS Amundsen in the Canadian Arctic

Summary:
The Canadian research icebreaker CCGS Amundsen is equipped with multi-plankton sampler system called Hydrobios. The MultiNet Type Maxi, part of the system, is used for vertical collections. An integrated CTD unit is also integrated to the system and allows recording of the sampled water characteristics. This dataset is composed of CTD profiles and specific data for the volume of water going through the nets during their operation. The Hydrobios was deployed during the Amundsen scientific expeditions in the summer and fall between 2003 and 2023 with the exception of 2004, 2005, 2009, 2011 and 2012, where no data is available. The integrated CTD sensors are from the Hydrobios company itself. In-situ data belong to and are under the responsibility of the leading Nets scientists while physical and chemical data from the sensors are part of the Amundsen core data collection.

The Hydrobios-CTD data were corrected and controlled by comparing them to CTD-Rosette data when available.  Outliers and suspicious measurements were removed from the dataset. Variables are provided for every 2 decibars (dbar) between the maximum and minimum pressure recorded for each cast.

Long-term oceanic observatories moorings data in the Beaufort Sea during ArcticNet study 2004-2010, reprocessed.

Summary:
Thirty-six moorings were deployed in the Beaufort Sea between 2004 and 2010. Some of the moorings were deployed for one year only and others were maintained (recovered and redeployed) over several years. A total of 12 moorings were lost (1 in 2004, 2 in 2006, 1 in 2007, 2 in 2008, and 6 in 2010). Mooring sites included the Mackenzie Shelf (North-Western to North-Eastern), Mackenzie Shelf slope, Kugmallit Valley, Canada Basin, Mackenzie Canyon, Amundsen Gulf (West to East), and outer Franklin Bay area. Bottom depth at deployment sites varied between 200 and 545 m. Mooring lines were equipped with various oceanographic instruments attached at different depths from 12 m to a maximum of 500 m below the surface. Moored instruments included ALEC conductivity-temperature-turbidity- chlorophyll-PAR sensors, SeaBird SB 26 and SB37 conductivity-temperature sensors, RMC4, RMC7 and RCM11 current meters, Nortek current profilers, McLane moored profilers and NIPR and Technicap sediment traps. The datasets available were quality controlled, and have been used in several publications listed in the document accompanying the data. Variables available include water temperature, conductivity (salinity), density, PAR, Chla, turbidity, oxygen and current velocity (speed and direction). Sediment trap collections were used to estimate downward fluxes of particles, and datasets are described in Metadata CCIN 10476 (Vertical particle flux data in the Beaufort Sea: 2002-2010).
This dataset is a reprocessed version of the previous one. The processing chain used is built upon open-source Integrated Marine Observatory System (IMOS) toolbox developed for Matlab© by the Australian Ocean Data Network (AODN; Galibert, 2016).

Mooring data of the Integrated Beaufort Observatory (iBO), a project from the Beaufort Regional Environmental Assessment (BREA) Marine Observatories in the Canadian Arctic.

Summary:
The iBO project has supported the deployment of four moorings at key locations identified during the previous northern and southern Beaufort Sea monitoring initiatives (see CCIN 11925 ArcticNet-Industry 2009-2011 moorings and CCIN 11975 BREA 2011-2015 moorings). Since fall 2015, BRG and BR1 from BREA were redeployed along with two new moorings BRK and BR3.  For every year of deployment, each mooring line was equipped with various oceanographic instruments attached at different depths from approximately 150 m to 750 m. Moored instruments include conductivity-temperature sensors, ice profiling sonars, particle analyzers, current meters, current profilers, and sediment traps. Datasets include currents, ice draft and velocities, water levels, temperature, salinity and turbidity, chlorophyll, suspended particulate size and concentration, and vertical carbon flux.

Data collected were quality assessed/quality controlled (QA/QC) following the Climate and Forecast (CF https://cfconventions.org/) conventions, and building upon the open-source Integrated Marine Observatory System (IMOS) toolbox developed for Matlab© by the Australian Ocean Data Network (AODN). The four moorings provided ready to use quality data for the period 2015-2017. BR1 provided an extra year of data for 2017-2018, whereas BR3, BRG, and BRK are still at sea and being recovered (Fall 2019). The program ended officially in 2018; however, Amundsen Science and its collaborators maintain the observatory and monitoring capacity in the region with one mooring BRG pending new funding and interests for the program.

For every year of deployment, each mooring line was equipped with various oceanographic instruments attached at different depths from approximately 150 m to 750 m. Moored instruments include conductivity-temperature sensors, ice profiling sonars, particle analyzers, current meters, current profilers, and sediment traps. Datasets include currents, ice draft and velocities, water levels, temperature, salinity and turbidity, chlorophyll, suspended particulate size and concentration, and vertical carbon flux.

Data collected were quality assessed/quality controlled (QA/QC) following the Climate and Forecast (CF https://cfconventions.org/) conventions, and building upon the open-source Integrated Marine Observatory System (IMOS) toolbox developed for Matlab© by the Australian Ocean Data Network (AODN). The four moorings provided ready to use quality data for the period 2015-2017. BR1 provided an extra year of data for 2017-2018, whereas BR3, BRG, and BRK are still at sea and being recovered (Fall 2019). The program ended officially in 2018; however, Amundsen Science and its collaborators maintain the observatory and monitoring capacity in the region with one mooring BRG pending new funding and interests for the program.

Moving Vessel Profiling (MVP) data collected by the CCGS Amundsen in the Canadian Arctic

Summary:
The Canadian research icebreaker CCGS Amundsen is equipped with a Moving Vessel Profiler (MVP), a versatile instrument designed to collect both shallow and deep water data sets without the need to halt the vessel. During transects, multiple consecutive casts of the MVP are conducted, facilitating the collection of data on the physical and chemical characteristics of the water column.

The MVP was deployed during the Amundsen scientific expeditions, spanning the summer and fall of 2004 to 2024, with the exception of 2005, 2006, and 2019. Data was unavailable for 2012 due to the ship undergoing maintenance. The system components underwent slight variations throughout the year, typically comprising a Micro CTD (Temperature, Conductivity, and Pressure), a Micro DO2 (Dissolved Oxygen), a Micro SV (Sound Velocity and Pressure), an ECOFLO (Fluorescence), and a C-Star (Transmittance) probe.

The MVP data were meticulously corrected and controlled by comparing them to CTD-Rosette and thermosalinograph (TSG) data whenever feasible. Comprehensive metadata and reports are provided to support the information presented and serve as documentation regarding the data processing methodologies.

ThermoSalinoGraph (TSG) data collected by the CCGS Amundsen in the Canadian Arctic

Summary:
The Canadian research icebreaker CCGS Amundsen is equipped with an underway ThermoSalinoGraph (TSG) system, which continuously records surface seawater temperature, salinity, fluorescence and sound velocity along the transit route. Quality Assurance/Quality Control (QAQC) data are available for the summer periods between 2005 and 2021, except in 2007, 2008 and 2012 where the system was faulty or the ship was in maintenance.

The TSG data were corrected and controlled by comparing them to CTD-Rosette data and in situ measures when available. Outliers and suspicious measurements were removed from the dataset. Variables are provided every 7 minutes.

Research programs participating in the Amundsen expeditions between 2005 and 2021 include, ArcticNet, CFL, Geotraces, Malina, IOL and BP, BREA, Weston, Netcare, JAMSTEC, Statoil and iBO, GreenEdge, BAYSYS, Sentinel Nord (BriGHT, BOND), DFO ROV vulnerable marine ecosystem, and the Kitikmeot marine Ecosystem.
