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

Keith Lévesque, Pascal Guillot, Thomas Linkowski, Simon Morisset & Juergen Zier
The Canadian research icebreaker CCGS Amundsen is equipped with BIONESS (Bedford Institute of Oceanography Net and Environmental Sampling System). It is a multiple-net sampler for zooplancton and micronekton (pelagic animals 1-10 cm in length). It uses a design with nets arranged horizontally rather than vertically. 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...

CTD data collected by the CCGS Amundsen in the Canadian Arctic

Keith Lévesque, Pascal Guillot, Forest Forest, Thomas Linkowski, Simon Morisset & Juergen Zier
CTD data are obtained during the annual CCGS Amundsen scientific expedition. A large number of CTD rosette casts are performed every year. The rosette has twelve 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...

TSG data collected by the CCGS Amundsen in the Canadian Arctic

Keith Lévesque, Simon Morisset, Thomas Linkowski & Juergen Zier
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.

The TSG data were corrected and controlled by comparing them to CTD-Rosette data and...

Acoustic data in the Canadian Arctic

Louis Fortier, Mathieu LeBlanc & Maxime Geoffroy
The dataset is composed of raw files (.raw) recorded with a SIMRAD EK60 three-frequency (38, 120, 200 kHz) split-beam echosounder that was operated continuously during the ArcticNet cruise aboard the CCGS Amundsen from 2006 to 2016 (no data were collected in 2012 due to the CCGS Amundsen being in dry dock).

Aerial-photo and LiDAR iceberg surveys during the 2015 Joint Statoil/ArcticNet Cruise, Newfoundland and Labrador, Canada

Derek Mueller, Anna Crawford, Gregory Crocker, Gabriel Joyal & Patrick Lajaunesse
Triplicate aerial-photo and LiDAR surveys of two iceberg sails were conducted to evaluate the capability of each technique to detect iceberg or ice island deterioration. This evaluation lays out how the spatial pattern and rate of iceberg deterioration could be measured with repeat surveys. 3D representations of the iceberg sails were generated from the aerial-photo surveys with the structure-from-motion (SfM) processing method as well as directly from the LiDAR data. The SfM data was scaled...

Sea ice drift data were obtained from an array of ten ice beacons and one ice mass balance buoy launched from the CCGS Amundsen in the marginal ice zone of the southern Beaufort Sea in September, 2009. From this array, four triangular configurations were selected, hereinafter referred to as triplets A to D, to monitor sea ice deformation with initial inter-beacon distances of approximately 11, 11, 11.5, and 7 km for the shortest leg, and...

2012-2013 mapping of mud ejections at Cape Bounty, Melville Island

Scott Lamoureux & Jean Holloway
