2018 Summary:
The goals of this research are to ascertain the formation of marine pockmarks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from degrading or thawing offshore permafrost.
The research team intend to document the seabed characteris...

The objective of the seabed mapping program is to conduct a regional survey of the Beaufort shelf. Ice scouring processes, benthic habitats, abandoned artificial islands, pingo-like features, gas seeps, seafloor foundation conditions, and subsea permafrost will be investigated.
The Coast Guard vessel CCGS Nahidik will be used as the research platform to conduct offshore acoustic/sonar surveys ...

Summary:
To continue the study and come to understand natural hydrocarbon distributions and primary productivity in the oil exploration zone of the Mackenzie Estuary. To predict the impact of projected industrial discharges of hydrocarbons, planned or accidental, by studying and model processes governing natural distributions of the same compounds....

Summary:
Geological investigations of the seabed in marine areas of the Canadian Arctic Archipelago: to obtain grab samples, short core and seabed photography; approx. 60 stations over a grid pattern; experiment with through-the-ice seismic reflection data using small charges as sound source to obtain information on sediment thickness and shallow stratigraphy....

Summary:
To conduct Phase II of Through-the-Ice-Sounding Study. Measurements will be made on rifle shots aimed vertically at the ice from a platform and firing shots at the ice from a helicopter to develop a non-contact through-the-ice sounding method....

Summary:
To carry out phase I of a bathymetric survey system. A tower will be built on the ice and a rifle (460 cal Weaterby) mounted on it. The rifle will be discharged into the ice and measurements made to determine the amount of sound transmitted to the water, the level of bottom echo detected in air etc....
