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...

Measuring Currents

Two major currents on British Columbia’s west coast, the California Current and Alaskan Current, carry water south and southwest respectively. Within NEPTUNE observatory, currents are measured using ADCPs and acoustic current meters. Each location needs to be examined independently since local bathymetry and geological features can affect the water flow.

An ADCP attached to a platform prior to deployment.

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...

Ocean Acoustics

Example of the readout from the Zooplankton Acoustic Profiler (ZAP).

In the terrestrial world, we rely heavily on optics and our vision, and less so on acoustics and hearing. In the ocean, the opposite is true. In coastal waters, light only travels relatively short distances (5-20m), so marine animals use light for sensing only the very near-field environment, while sound can travel huge distances (1-1000km), and informs marine animals of distant features and events. Marine scientists also take advantage of the efficiency with which sound travels in the ocean, and use it to both investigate and...
