Ocean Properties

Oceanographers and marine scientists measure or observe attributes or properties of the ocean that allow them to interpret water or component or organism behaviour. Although Ocean Networks Canada cannot measure all required parameters, many instruments are available to provide useful data.

This section discusses the properties measured and provides links to the instruments that provide all or part of the information. Not all parameters are measured at all locations, and some locations have more than one instrument that will measure the same feature in different ways.

Bottom Animal Behaviour

Sometimes biologists have to see animals to understand their actions related to abundance, feeding, competition, and mating. Thus, a camera on the seafloor can often reveal...

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...

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.

Autonomous Mooring at Saanich Inlet Sill

On 7 September 2012, Paul Macoun and Richard Dewey headed out with the Ocean Technology Laboratory (OTL-UVic) engineers Emmett Gamroth and Jeff Kennedy to deploy a small autonomous (internally recording) mooring just inside the sill at the entrance to Saanich Inlet. The mooring includes a Seabird CTD with oxygen sensor and a 300kHz RDI Acoustic Doppler Current Profiler. It was deployed at 48 41.301N 123 30.024W in 90m of water.

Sediment Mix-Masters

The seafloor is, arguably, one of the most extensive habitats on the planet and it is significantly understudied. It is home to a variety of benthic organisms that spend much, if not all, of their time on the bottom sliding along or ploughing through sediment. Some organisms are deposit-feeders that ingest sediments, absorb their organic content, and excrete faecal strings or pellets; other organisms are burrowers that actively mix sediments vertically. This process by which organisms mix up sediment, is known as bioturbation, and is ecologically important because it influences nutrient recycling and other biogeochemical processes on the seafloor.

Bioturbation has traditionally been studied using time-lapse imagery or vertical tracers (natural or artificial objects on the...

Storm Watching

19-23 January 2012:

 An intense windstorm left thousands of Vancouver Islanders out of power and forced BC Ferries to suspend service to the mainland on the 22nd. Wind gusts exceeding 110km/h were recorded in places, as a train of intense low pressure systems struck Vancouver Island's west coast one after another. Wave buoy data at the La Perouse Bank (located approximately 50km northwest of Folger Node, ISDM ID online data: C46206) showed extreme waves reaching as high as 18m on 22-23 January.

ADCP Velocity Plots now available

Although we have been collecting Acoustic Doppler Current Profiler (ADCP) data for over two years from various locations in the Strait of Georgia, real-time plots of the data have only recently been added to the Data Plots section. Shown here is a single day of data from the Eastern Strait of Georgia site, showing (top panel) the East/West component, (second panel) the North/South component, (third panel) the Up/Down (vertical) component, and (forth panel) the average back-scatter intensity.

Folger Pinnacle Frontiers

​

The Folger Pinnacle instrument platform was installed on August 23, 2010 and connected on February 2, 2011 by a combined team of Pelagic Technologies divers, the Bamfield Marine Sciences Centre (BMSC), and Ocean Networks Canada. Since then, a wealth of data has been gathered by instruments affixed to this 23m deep platform. However, in recent months, Dilumie Abeysirigunawardena, one of our data specialists, noticed a drop in the instruments’ data quality and sensitivity. Some stopped working altogether, while signals from others have gradually diminished. (See, for example, the drop-off in irradiance from our light sensor below – you’d normally expect June to be brighter than February!)

From July 4 - 25, 2011, Ocean Networks Canada navigated an impressive installation and maintenance expedition in the northeast Pacific Ocean. Diving down to the seafloor to investigate our 800-km cabled network observatory along the northern Juan de Fuca plate, we tended to our technically-advanced instruments and witnessed some of the amazing marine life dwelling off the coast of Vancouver Island, British Columbia.
