This dataset contains the complete expedition report, the expedition map as well as a list of stations and sampling types. The 2020 Expedition Report describes scientific expedition carried out on the CCGS Amundsen in the Canadian Arctic between July 16 and October 27, 2020. The report is a collection of all the participating research teams’ Cruise reports assembled by the Chief Scientists at the end of LEG 1, LEG 2 (a, b and c) and LEG 3 of the CCGS Amundsen Expedition. The 2020 Expedition Report is divided into two parts:

Part I gives an overview of the expedition, shows the cruise track and the stations visited and provides a synopsis of operations conducted during each of the three LEGs.

Part II contains the reports submitted by participating science teams or researchers, with details on the specific objectives of their project, the field operations conducted and methodology used, and in some cases, preliminary results. When results are presented, they show the data as they were submitted at the end of the legs in 2020. The data presented in the report are illustrative only and have not been quality checked, thus parties interested in the results should contact the project leader or the researchers who collected the data. The sections in Part II describing each project are organized with multidisciplinary project reports. Subsequent sections cover Biological sampling, water column properties, benthos sampling from the ROV (Remotely Operated Vehicle) and seabed mapping.

The four Appendices provide details on the locations and type of sampling performed at each station visited by the ship, as well as a list of science participants onboard during each LEG. 

A [**summary of the 2020 expedition**](https://catalogue.ogsl.ca/en/dataset/ca-cioos_462fdf6e-df19-441f-a511-c95db4d3d2fc) is also available in English.

The core oceanographic data generated by the CTD-Rosette operations, as well as meteorological information (AVOS : Automated Voluntary Observing Ship; Environnement Canada) and data collected using the Moving Vessel Profiler (MVP), the ship-mounted current meter (SM-ADCP) and the thermosalinograph (TSG) are available in the [**Polar Data Catalogue (PDC)**](https://www.polardata.ca/pdcsearch/?doi_id=12713)

It is possible to consult an [**interactive map**](https://data.amundsen.ulaval.ca/) including all the years of expeditions and the different trajectories (LEG) associated with them.
