Introduction to Middle Valley

A fish guards the site for ONC's proposed Middle Valley observatory.

Introduction:

Ocean Networks Canada is looking to expand its current observatories in the northeast Pacific by installing a node module at a sixth site, which already possesses much of the required infrastructure. This site, located at the Middle Valley on the Juan de Fuca ridge, was originally...

MicroSquid Experiment

The objective of MicroSquid project is the collection of continuous measurements of oxygen uptake by the seabed in Saanich Inlet, British Columbia. The work is an exceptional international collaboration and is adding pioneering capabilities to the VENUS cabled ocean observatory. The partners in this research are scientists, technicians, and engineers from Oregon State University' Reimers Lab, Rockland Scientific (BC, Canada), and Ocean Networks Canada.

This research focuses on understanding what drives changes in benthic oxygen flux, which is a measure of how much oxygen sediment biota consume from the overlying water. Concurrently, we are testing a new instrument’s ability to collect data via an ocean observatory...

Saanich Inlet Hypoxia Paper Published

Saanich Inlet Digital Camera data

For a year, the VENUS camera photographed the same area of seafloor in Saanich Inlet. A recent paper examines the response of the benthic animals to changing levels of oxygen. Only a few species cope with hypoxia but the high numbers suggest that food availability and refuge from oxygen-starved predators is a good strategy for some. The research predicts marked changes on the continental shelf with growing “dead zones”.

Assessing Biorhythms in Saanich Inlet

Assessing Biorhythms in Saanich Inlet

Studying biorhythms in Saanich Inlet is an ongoing research project supported by Ocean Networks Canada. Following the initial deployment and analysis of results, published in Sensors (Aguzzi et al. 2011), the group of international collaborators is now using a seafloor camera (DISCo) that features a more developed control interface. The interface can automate the process of turning the...
