CSZ: Cascadia Subduction Zone

Planned systematic 2D multichannel seismic investigation of the Cascadia Subduction Zone using an ultra-long (15 km) hydrophone streamer. Funded by the US National Science Foundation.

QCF: Queen Charlotte Fault

Planned 2D multichannel seismic, and short- and long-period ocean bottom seismometer survey of a ~450 km segment of the Queen Charlotte Fault hypothesized to show variations in the Pacific and North America plate convergence, from subduction initiation in the south to pure strike-slip motion in the north. Funded by the US National Science Foundation, Natural Sciences and Engineering Research Council of Canada, and US Geological Survey.

NJ3D: Geomorphology and Neogene Sea-level Change Offshore New Jersey

A 600 square kilometer ultra-high resolution 3D P-cable seismic survey encompassing the three IODP Expedition 313 drillsites on the inner-middle shelf of New Jersey. Data collected in 2015 during R/V Langseth cruise MGL1510 with funding from the US National Science Foundation.

SeaJade: Seafloor Earthquake Array - Japan-Canada Cascadia Experiment

The Seafloor Earthquake Array - Japan-Canada Cascadia Experiment (SeaJade) is a multiyear, two-phase collaborative project to study the seismicity offshore in the northern Cascadia subduction zone, especially near the megathrust, in order to better understand the state of the locked zone. Passive seismic data was collected with short-period OBS instruments in 2010 and 2014.

SismoSmooth: Characterization of the Ultraslow Spreading SW Indian Ridge

A 2D/3D near-offset multichannel seismic and wide-angle ocean bottom seismometer survey to characterize exhumed ultramafic seafloor at the ultra-slow spreading Southwest Indian Ridge. The survey was conducted in 2014 using R/V Marion Dufresne with funding from Flotte Oceanographique Francaise of France and Natural Sciences and Engineering Research Council of Canada.

R2T: Ridge to Trench Experiment Across the Juan de Fuca Plate

Ridge-to-trench study of the structure and evolution of the Juan de Fuca plate using multichannel seismic and ocean bottom seismometer profiling. Project carried out in 2012 using R/V Langseth (cruise MGL1211) and R/V Oceanus (cruise OC1206A) with funding from the US National Science Foundation and Natural Sciences and Engineering Research Council of Canada.

ALEUT: Alaska Langseth Experiment to Understand the megaThrust

Regional controlled source seismic mapping of the Alaska-Aleutian megathrust using multichannel seismic and ocean bottom seismometer profiling. Project carried out in 2011 using R/V Langseth (cruise MGL1110) with funding from the US National Science Foundation and Natural Sciences and Engineering Research Council of Canada.

OBWAVE: Orphan Basin Wide-Angle Velocity Experiment

A wide-angle ocean bottom seismometer profile in the Orphan Basin offshore Newfoundland to investigate the hyper-extended continental crust of this abandoned rift basin. The survey was conducted in 2010 using R/V Explorer with funding from ExxonMobil.

OCTOPUS: Ocean-Continent TransitiOn Profile Using Seismics

A wide-angle ocean bottom seismometer profile at the transition from non-volcanic to extreme amagmatic rifting associated with a major change in crustal reflectivity. The survey was conducted in 2010 using R/V Explorer with funding from the Natural Sciences and Engineering Research Council of Canada.

OETR: Continent-Ocean Transition Across the NE Nova Scotian Margin

A dense wide-angle ocean bottom seismometer profile offshore northeastern Nova Scotia for detailed characterization of the presumed highly amagmatic continent-ocean transition. The survey was done in 2010 using R/V Explorer with funding from Offshore Energy Technical Research (OETR) association.

EPR3D: Magmatic Plumbing at the Fast-Spreading East Pacific Rise

This first multi-source and multi-streamer 3D multichannel survey across a mid-ocean ridge covered ~1000 square kilometer area of the East Pacific Rise at 9°50'N with the goal to investigate the magmatic plumbing of the crust and uppermost mantle. The survey was carried out in 2008 using R/V Langseth (cruise MGL0812) with funding from the US National Science Foundation.

ROSE: Reflection Ocean Seismic Experiment

Seismic oceanography survey on the Scotian slope using coincident multichannel seismics and XBT/CTD profiling. The survey was carried out in 2007 using R/V Endeavor (cruise EN438) for collection of oceanographic data with funding from the Natural Sciences and Engineering Research Council of Canada and an industry ship chartered by the Geological Survey of Canada for collecting multichannel seismic data.

SMART: Scotian MARgin Transects

Wide-angle ocean bottom seismometer profiling offshore Nova Scotia to understand what controls the transition from volcanic margins to non-volcanic margins. The survey was conducted in 2001 on CCGS Hudson as part of the MARIPROBE Project funded by the Natural Sciences and Engineering Research Council of Canada and the Geological Survey of Canada - Atlantic.
