With media coverage of the recent earthquakes in Italy, New Zealand, Japan, Papua New Guinea, you might be wondering whether earthquake activity is increasing. Long-term earthquake statistics in the last 12 months indicate that it was an average year: there were no earthquakes of M8.0 or higher (one M8.0+ is the annual average) and 19 earthquakes with M7.0 - 7.9 (17 is the annual average). When in doubt, turn to scientific facts, especially in the post-truth era.

A five-year, $46.6 million investment from the Canadian government—through the Canada Foundation for Innovation (CFI)—will ensure that Ocean Networks Canada continues to lead the world in ocean observatory science and technology.

In June 2014, ONC installed a cabled water column profiling system in Saanich Inlet. The inshore profiling system consists of a surface buoy equipped with a meteorological station and a winch used to raise and lower an underwater instrument package through the water column. This year, University of Victoria postdoctoral researcher Jeff Sorensen is leading a project to study how the chemistry of the Saanich inlet changes over the course of a year.

How do you determine when a system has become oxygen deficient, or hypoxic, for the species in our marine ecosystems? Part of the answer comes from mapping where species are found in their habitat and then repeatedly mapping their habitat under changing oxygen conditions.

Ocean Networks Canada visiting scientist Pere Puig is a marine geologist whose expertise in deep sea sediment dynamics is contributing to our growing understanding of the importance of submarine canyons. And, as the grandson of a shrimp fisherman in northern Spain, Pere’s research is also having a direct influence on Mediterranean fishing practices.

In late summer 2016, Cambridge Bay, Nunavut found itself at the centre of an arctic crossroads of sorts: a pivotal meeting place where ice-bound history is melting into climate science. A week after the first luxury cruise ship sailed through a virtually ice-free Northwest Passage and anchored in Cambridge Bay, the wreck of Franklin’s ship The Terror was finally discovered just 200 km east. The coincidence in time and place of these two iconic voyages poignantly highlights how quickly the arctic climate is changing, the need to monitor these changes, and the growing importance of Cambridge Bay as an emerging arctic hub.

Congratulations to Dr. Kelin Wang for being elected a Fellow of the American Geophysical Union (AGU), an honour provided to only 0.1% of AGU’s 62,000 plus members. Kelin and his students are studying the geodynamics of subduction zones, especially processes related to the generation of large earthquakes and tsunamis around the world. His models for earthquakes inform building codes, risk assessments, and tsunami preparedness along the Pacific coast of North America. This work is relevant to the tsunami research being done at Ocean Networks Canada (ONC).

Ocean Networks Canada’s (ONC) Expedition 2016: Wiring the Abyss returned to port on June 25 after 40 days at sea off the west coast of Canada. This ambitious undertaking involved 149 people aboard three ships, and included three remotely operated vehicles (ROV) making 44 dives to deploy, maintain and recover 180 instruments and lay 18 km of fibre-optic cable. The dynamic 24/7 operations engaged viewers across the world via live stream and featured regular Q&A with scientists, educators and engineers. 

The experiment includes three packages: one contained three rib sections of a humpback whale (stranded in Alaska several years back); another contained a block of Douglas Fir; and a third contained a large piece of carbonate collected from a methane seep located off the coast of California.

Life under water changes with the seasons just like it does above water. Read about the marine spring bloom and how we track it.

Supporting the diverse research activities that use ocean observatory data is an ongoing and evolving effort.  ONC's research community contributes to operational planning and strategic development through the Ocean Observatory Council and the Theme Leaders.

According to recent studies, roughly 10,000 submarine canyons exist worldwide. Only 1% have been studied in any detail.

Award-winning poster: What would happen if the Cascadia subduction fault ruptured, or broke, in the same way as the 2011 Tohoku earthquake? 

Unseen beneath the surface of the Arctic Ocean, the Ocean Networks Canada ocean observatory in Cambridge Bay, Nunavut, monitors ocean conditions 24/7. During the night of 13 October, sensors detected the seasonal return of surface sea ice.
