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

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 Conductivity, Temperature, Depth (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 2019 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. 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. Research programs participating in the Amundsen expeditions between 2003 and 2016 include CASES, ArcticNet, CFL, Geotraces, Malina, IOL and BP, BREA, Weston, Netcare, JAMSTEC, Statoil, iBO, GreenEdge, BAYSYS and Department of Fisheries and Oceans (DFO) programs. 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.

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

The Canadian research icebreaker CCGS Amundsen is equipped with a Moving Vessel Profiler (copyright) (MVP), a multi-purpose instrument used to collect both shallow and deep water data sets, without the need to stop the vessel. Data on physical and chemical characteristics of the water column are collected during transects along which several consecutive casts of the MVP are conducted. The MVP was deployed during the Amundsen scientific expeditions, in the summer and fall of 2004 to 2018 with the exception of 2005 and 2006, where no data is available, and 2012 because the ship was undergoing maintenance. The components of the system varied slightly throughout the year but typically included a Micro Conductivity, Temperature, Depth (CTD) (Temperature, Conductivity and Pressure), a Micro DO2 (Dissolved Oxygen), a Micro SV (Sound velocity and Pressure) and an ECOFLO (Fluorescence) and a C-Star (Transmittance) probe. The MVP data were corrected and then controlled by comparing them to CTD-Rosette and thermosalinograph (TSG) data when available. Variables are provided for every decibar (dbar) between the maximum and minimum pressure recorded for each cast. Detailed metadata and reports are included to provide more information.

Snow density, temperature, and hardness at Concordia Station, Antarctica

This dataset reports the snow density, temperature and hardness observations from the surface to 1 m depth at the Concordia Station, Antarctica. A snow trench is dig once per month (or every three months during winter) in the clean area near the Station (< 1 km). The snow density measurements are taken inserting a core barrel (with a diameter of 4.5 cm and a length of 25 cm) horizontally into the snow every 10 cm from 0 to 1 m depth. The snow density is calculated from the weight. For each layer the temperature and the hardness (ranging from 1 to 6) are also recorded.

Snow height at the Gruvebadet Snow Research Site (NY-Alesund, Svalbard, Norway)

The automated nivological station was installed in November 2020 in a flat area over the tundra about 80 meters far from the Gruvebadet Atmospheric Laboratory and nearby a snow sampling site from where weekly snow samples are collected for chemical analysis. Sensors have been calibrated by their companies before installation and are connected to a datalogger for continuous acquisition. For all the parameters, data are logged with 10-minute time resolution and then averaged over 1 hour.

Snow temperature at the Admunsen-Nobile Climate Change Tower (Svalbard, Norway)

The automated station is operating at the Amundsen-Nobile Climate Change Tower since 2010, which is in a tundra site almost flat, located in the Kolhaugen area. The station is part of a complex infrastructure where multi-disciplinary observations are routinely performed.

Snow temperature at the Gruvebadet Snow Research Site (NY-Alesund, Svalbard,
Norway)

The automated nivological station was installed in November 2020 in a flat area over the tundra about 80 meters far from the Gruvebadet Atmospheric Laboratory and nearby a snow sampling site from where weekly snow samples are collected for chemical analysis. Sensors have been calibrated by their companies before installation and are connected to a datalogger for continuous acquisition. For all the parameters, data are logged with 10-minute time resolution and then averaged over 1 hour.

Stakes height at Concordia Station (Antarctica)

This dataset reports the height observations of the Italian stake farm at the Concordia Station, Antarctica. The stake farm consists of 13 stakes, separated from each other by 10 m, arranged in a cross shape structure, located approximately 800m southwest of the Station and sampled on monthly basis or so.

TSG data collected by the CCGS Amundsen in the Canadian Arctic

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 2020, 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 2020 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.

Turbulent parameters at the Amundsen-Nobile Climate Change Tower (Svalbard) (turbulence cct)

Turbulent parameters are measured at the Amundsen-Nobile Climate Change Tower (CCT) by means of a Gill R3 sonic anemometer installed at 7.5 m from the ground since 2010. It measures the three components of the wind (u, v and w measured in m/s) and the sonic temperature (expressed in Kelvin degrees) at a rate of 20 Hz. These micro-meteorological measurements are complemented by standard meteorological ones at 4 levels: 2, 5, 10 and 33 m (acquisition time step 1 minute).
