This dataset contains the complete report, the expedition map as well as a list of stations and sampling types. The 2021 Expedition Report describes the scientific expedition carried out in the Canadian Arctic between July 04 and November 3, 2021. The report is a collection of all the participating research teams’ Cruise Reports provided to the Chief Scientists at the end of each LEG of the 2021 CCGS Amundsen Expedition. The 2021 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 five 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 2021. 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, the researchers who collected the data or Amundsen Science’s Data Coordinator (amundsen.data@as.ulaval.ca). The sections in Part II describing each project are organized with atmospheric, surface ocean and sea ice components first, followed by water column properties, which include the mooring and buoy program, CTD-Rosette operations and physicochemical properties, as well as a suite of biological parameters and benthos sampling. Subsequent sections cover sediments sampling and seabed mapping.

Five Appendices are included, documenting visited stations and performed sampling as well as a list of science participants onboard during each leg. A description of each ROV (Remotely Operated Vehicle) dive is also attached. 

[**Summaries of the 2021 expedition**](https://catalogue.ogsl.ca/dataset/ca-cioos_f77fe17d-c2cb-4edd-b76e-1e4ff45ceaa3) are also available in 3 languages (French, English, Inuktitut).

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.
