The concentrations of dissolved nutrients (nitrate, nitrate, phosphate, and dissolved silica) were measured on board ship with a nutrient autoanalyzer to complement the...

The CTD data was obtained during LEG 08 of the 2004 CASES scientific cruise #0405. This Leg was carried out from June 25th 2004 to August 5th 2004 aboard the CCGS Amundsen....

Our sampling program took place from August 27, 2009 through September 12, 2009. It was part of Leg 3a of the 2009 CCGS Amundsen Expedition in the Arctic Ocean (ArcticNet 0903)....

Digital coastlines from the Canadian Beaufort Sea were generated from accurately georeferenced aerial photography (1950-2004) and satellite imagery (2010 - Worldview 1&2),...

The autotrophic and heterotrophic protist communities were examined by fluorescence microscopy. 225 ml of water was preserved with glutaraldehyde (final concentration of 0.5...

The following dataset represents cliffs, beach and coastlines as they existed along the Beaufort Sea since 1947. These features provide an accurate representation of the...

The concentrations of nitrate, nitrite, orthophosphate and orthosilicic acid were determined on fresh or frozen water samples using an Autoanalyzer 3 (Bran+Luebbe) with...

Although the regional distribution of bacterioplankton was best explained by salinity (r = -0.89, n = 28, p < 0.001) and indicators of primary production (chlorophyll a [Chl...

Environment Canada installed a meteorological system on the Voluntary Observing Ship (VOS) scheme part of the CCGS Amundsen. The system is composed of a Digital Barometer...

The CTD data was obtained during the 2007-2008 ArcticNet scientific cruise #0706. The data were collected from October 15 to November 6, 2007, aboard the CCGS Amundsen. There...

The data set is an image of colour-shaded sun-illuminated seafloor topography collected from Mackenzie Delta in the Beaufort Sea in 2007 by the Geological Survey of Canada...

The distribution of dissolved inorganic nutrients (NO3 + NO2, PO4, Si(OH)4) and oxygen isotope 18O in the Beaufort Sea was investigated in the summer of 2012, as part of the...

Samples were filtered for particulate lignin through pre-cleaned and baked Whatman GF/F filters. Filtrate was processes with whole water samples through serial 3 micro and then...

During the 2007-2008 CFL IPY Project, the research icebreaker CCGS Amundsen overwintered in the South Beaufort Sea/Amundsen Gulf flaw lead system. The purpose of this...

Field work and airphoto studies were undertaken between 1953-1996 along the Yukon coast of the Beaufort Sea in Ivvavik National Park to determine coastal erosion rates,...

This dataset consists of vertical profiles of underwater downwelling irradiances at several UVR (305, 313, 320, 340 and 380nm) and PAR wavelengths, from June to August 2004....

The concentrations of nitrate, nitrite, orthophosphate and orthosilicic acid were determined on fresh or frozen water samples using an Autoanalyzer 3 (Bran+Luebbe) with...

Zooplankton were collected from the Canadian Beaufort Sea shelf in July and September 1984, and July to September 1985. In 1984, 18 net samples were collected with 763 µm...

The IR Transducer is installed at the 400 level of the CCGS Amundsen icebreaker on the port side of the ship. The data recording is done on a separate storage module and then...

The EM sensor operated at 9 kHz and provides both logged and real-time ice thickness information. Typical accuracy of the system is generally about 1% under 0.2-5m sea ice, 1-5%...
