Check the related data sourcesmaps page for information about other co-located and related data sources that may be useful for your studies and/or research.

...

One thing anyone can do from anywhere is participate in our Citizen Science project, Digital Fishers. Using Digital Fishers and a smart phone, you can help scientists study deep-sea marine life and features. 

...

Interested scientists and graduate students may request to join one of Ocean Networks Canada's installation & maintenance expeditions, please - contact ONC with your interest.

Learn more about expeditions. 

How can I propose an experiment?

Ocean Network Canada's seafloor observatories are built for researchers. A wide variety of instruments are installed already and this data is available for free. The observatory's modular design allows for new experiments and equipment to be plugged into our existing networks.  If you are preparing a proposl proposal to a funding agency for funds to develop an observatory experiment, we can assist. To get assistance and information on accessing installed instruments or deploying a new system to support your research, contact the Associate Director, Science Services who will connect you with the appropriate staff scientist focused in your specific research area. ONC secures funds to maintain and operate the observatory infrastructure. ONC does not have funds to support the development and installation of new systems, but we are keen to assist in your efforts to form new collaborations with existing observatory researchers and to obtain external funding.

Where is Endeavour and how did it get its name?

Endeavour is Endeavour is one of the important study sites on the NEPTUNE Observatory. It is located on the Endeavour segment of the Juan de Fuca mid-ocean ridge. This ridge segment was likely named after the Canadian Navy Auxiliary Vessel (CNAV) Endeavour, after its identification by Sandra Barr and Richard Chase in 1974. This vessel, in turn, was named after British explorer Captain James Cook's ship the HMS Endeavour, which was the first British ship to reach the east coast of Australia. During Cook's third voyage of exploration, on 29 March 1778, his ships landed at Friendly Cove on Nootka Island, along the west coast of Vancouver Island. They also visited Bligh Island and Resolution Cove, where Cook had the HMS Resolution repaired. Maps showing the ship's track from Cook's 3rd expedition indicate that he likely sailed over the Endeavour Ridge segment nearly 200 years before it was identified by the Barr and Chase aboard the CNAV Endeavour.

Historically the Strait of Georgia has supported both resident and transient orca whale pods. In the last few years, the resident whales have periodically migrated as far way as northern California. Why? When? For how long? Ocean Networks Canada's hydrophones monitor whale movement, record and allow us to better learn their vocabulary, and allow us to monitor their use of the southern Strait. Learn more.

Do different groups or pods of orcas have different vocal "accents"?

Orcas are one of few species that are known to exhibit culture, and one of fewer still with different cultural groups inhabiting the same geographic area without interacting with one another. Cultural groups of orcas differ in vocal dialect, social organization, behaviour, prey and hunting tactics. Some groups have not interbred with others for hundreds of thousands of years, and may actually be different species. Northern Resident orcas associate in 3 different acoustic clans, while Southern Resident orcas have a single acoustic clan. More about orcas and killer whales.

Can we see changes in the physical properties and the chemical composition? Ocean Networks Canada (ONC) provides a monitored, consistent extension to the periodic ship observations that show the seasonal and longer variations of our local waters. The long-term records produced by ONC's instruments measure longterm changes in temperature, salinity, seawater density, tides, and dissolved gasses. To see current conditions compared with historical records, see the Ocean Report Card. To view measurements over time in various locations, see the State of the Ocean plots.

Is the ocean getting louder?

Many processes can generate sound in the ocean. Atmospheric disturbances such as rain, hail, and wind all produce unique audible signatures. Human activities, most notably boat and ship engine noise, can produce persistent back-ground noise underwater. Ocean Networks Canada hydrophone arrays monitor the sounds in the Salish Sea, northeast Pacific, and allow researchers to identify natural and anthropogenic sound sources. For a daily vessel noise index in the Salish Sea, see the Ocean the Ocean Report Card

OCEAN DYNAMICS

How do tides and the Fraser River influence the marine ecosystem?

...

By 2014-2016, the slow spreading and dispersion of the contaminated seawater originating from the Fukushima Dai-ichi Nuclear Power Plant reached radioactivity concentrations that are similar to the pre-existing oceanic concentrations, making them difficult or impossible to detect/identify. Naturally occurring oceanic radionuclides dominate the radioactive signal from seawater, not only across the entire Pacific, but even in the near-field regions along the east coast of Japan as measured in early 2012. Additional background information.

When was the last megathrust subduction earthquake in the northeast Pacific?

The last megathrust subduction earthquake to occur along the Cascadia subduction zone happened on 26 January 1700. he earthquake magnitude was estimated as 9.0 and it resulted in a tsunami that was recorded in Japan. Evidence of this earthquake can be confirmed by geological evidence (land level changes, tsunami traces, turbidite deposits), biological evidence (tree rings), and human records (Native American stories and Japanese records). Megathrust earthquakes tend to occur in this region approximately every 300-500 years. More about the Cascadia subduction zone.

How high will a tsunami reach above the shoreline?

Without site-specific modelling (which has not been done for many places), it is very difficult to estimate how large tsunami waves could be at specific locations. However, any shoreline could be vulnerable, depending on the type the type of tsunami. Earthquakes are one of the primary causes of tsunamis, but they can also be caused by near-shore and underwater landslides, near-shore and underwater volcanoes, man-made explosions on or underwater, and even by space objects impacting water bodies.
