Chatham Sound is situated in the northern part of British Columbia, located between Dundas and Stephens Islands and the Tsimpsean Peninsula near Prince Rupert and bordering on Alaska. It is a semi-enclosed basin with an area of approximately 1500 km2, ...

Sidescan sonars use a swath of sound to esonify the seafloor. They differ from single-beam sounders in that they have a much larger footprint shape.

As a part of a project for Mavi Innovations Inc., Ocean Ecology developed an ocean circulation model for a region around Kaien Island. ROMS (Regional Ocean Modeling System) was chosen to carry out the ocean current studies. ROMS is a ...

Generally situated in shallows and along complex shorelines highly valued by recreational users, eelgrass meadows are both ecologically valuable and potentially threatened. They provide rearing habitats for the juvenile stages of many species of fish, foraging habitats for both migratory ...

Ocean Ecology designed a towfish system to carry out seafloor mapping which used a single-beam sounder transducer mounted in a highly streamlined towfish that was towed at 1.5 m depth from an A-frame at the stern of our ship. This ...

Fisheries management draws on fisheries science in order to find ways to protect fishery resources so that sustainable exploitation is possible. Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on ...

The Skeena is the second largest river in the province, and one of the longest un-dammed rivers in the world. The Skeena River estuary is a unique system in that it does not have a single distinct intertidal delta typical ...

A single-beam sounder calculates the depth below the ship using the time it takes a sound pulse to travel to the seafloor, reflect, and then return back to the transducer.

Based out of Prince Rupert, we used our 40 foot research boat, the Moody Blue, and our 33 foot sail boat, the Awen, to carry out community-based, independent, scientific (biology, chemistry, and oceanography) research. We used low-cost, appropriate technology for ...

As a part of our approach to our work, we are always looking for ways to reduce our impact on the environment. After an evening’s discussion with like-minded friends, we started putting our minds to the question “What would a ...

Much of the research work that Ocean Ecology was involved in could be described as habitat mapping. When habitat mapping is carried out in the marine environment, the product is generally referred to as a “benthic habitat map” – a ...

The USAT Brigadier General M. G. Zalinski was a U.S. Army transport ship that served in both World War I and World War II. She was a steel ship 251 feet in length, 44 feet in width, and 26 feet ...

Mutibeam sonars, like side-scan sonars, use swath technology. However, unlike side-scan sonars, multibeam sonars produce better depth (bathymetry) data than backscatter data. Although backscatter is also recorded, the imagery acquired is generally of a lower quality than that recorded from ...

The Skeena River originates high in the coastal mountains of northwestern British Columbia, at the edge of the Spatsizi Plateau, and flows 610 km to reach the Pacific Ocean. Draining a total area of 54,400 km2, the Skeena is the ...

The Northcoast region has been undergoing dramatic changes with respect to how natural resources are being utilized. There is a need to diversify the resource industries in the community so that resources which are currently under stress will not be ...

Pacific herring, small, silver-coloured fish, are the most abundant fish species in Canada’s Pacific coastal waters. About 500 linear kilometres of British Columbia’s coastline turn milky-white every March and April, as a result of the herring’s release of countless sperm ...

Eelgrass beds are both ecologically valuable and potentially threatened. They fall within the “critical” category of DFO’s habitat rating system, and DFO has concluded that eelgrass has characteristics which meet the criteria of an Ecologically Significant Species. The United Nations ...
