Partnering to Expand Ocean Networks' Reach from Sea to Sky

Ocean Networks Canada (ONC) is partnering with researchers and organizations to add critical ocean sensors from sea to sky.

Using light to understand our ocean

ONC and Dr. Maycira Costa of the University of Victoria (UVic) are working together to install a ferry-based sensor system focused on the calibration of satellite data for ocean health monitoring.

Observing Seasonal Marine Changes with BC Ferries

​

BC Ferries takes a closer look at the 2016 spring bloom in the Strait of Georgia

Every year, March brings two kinds of spring blooms to the temperate British Columbia coast: one involves an annual flower count, which is the envy of the country; the other turns the Salish Sea green with an explosion of marine productivity. BC Ferries plays an important role on both counts, bringing visitors across the Strait of Georgia to enjoy the Island’s blossoms while simultaneously hosting Ocean Networks Canada’s (ONC) instruments that collect marine data in the Strait of Georgia.

ONC measures ocean properties at the sea surface using advanced instruments installed onboard three ferry routes. The route from Departure Bay to Horseshoe Bay was instrumented...

Spring Bloom Observed in Ferry Data

The biological transition from winter to spring conditions in the Strait of Georgia is characterized by a spring phytoplankton bloom. Inter-annual timing of this phytoplankton bloom can vary by up to 6 weeks (Collins et al. 2009). This broad time range introduces the potential for a mismatch in the timing of the major annual period of zooplankton productivity in the Strait, which can in turn, influence the productivity of higher trophic levels such as fish and sea birds. Understanding the dominant factors influencing the timing of the bloom is therefore the subject of considerable interest (Collins et al. 2009; Allen & Wolfe 2013; Gower et al. 2013).

‘Dancing’ on the Seafloor—Saanich Inlet, 96m depth

The time lapse captures changes on the seafloor in Saanich Inlet at 96 metres depth as recorded by a VENUS camera in May 2012. Twelve days of still photos, taken by the DISCo camera, one every 30 minutes, were compressed into a 30 second video to show how animals move around in a natural setting in response to changes in the environment. During the time period captured in the video, a small phytoplankton bloom occurred at the surface of Saanich Inlet over the study area. The bloom eventually settled to the bottom and was followed by a migrating army of squat lobsters into the frame at the end of the video.
