VENUS

• 1. Introduction

  ›

  Three hundred meters beneath the Strait of Georgia, a camera watches the dark seafloor and never blinks. This is VENUS, the Victoria Experimental Network Under the Sea, one of two principal cabled seafloor observatories run by Ocean Networks Canada at the University of Victoria in British Columbia. Most ocean science depends on a ship that sails out, takes a measurement, and sails home. VENUS works differently. It studies coastal oceans near Victoria and Vancouver from instruments that stay on the bottom and report back without pause. How does a permanent eye underwater change what scientists can see? And why would anyone want the public watching too?

• 2. A Continuous Film

  ›

  Ship-based ocean research gives only a snapshot view. VENUS was built to replace that snapshot with something closer to a continuous film, allowing more reliable long-term observation. Since its launch in 2006, the network has let scientists run and monitor ocean experiments remotely, without standing on a deck above the water. Its sensors measure temperature, salinity, and the pressure of the water 24 hours a day. That steady stream reaches oceanographers, marine biologists, and geologists as real-time ocean data, the kind of record that captures change as it happens rather than long after.

• 3. Two Sites Below

  ›

  Saanich Inlet holds the first site of the VENUS seafloor network, operational since February 2006 and sitting at 100 meters. The second site reaches into the deeper waters of the Strait of Georgia, where instrument arrays are deployed at depths varying from 100 to 300 meters. The design draws on Internet and telecommunication technology, tied together by a network of about 50 kilometers of fiber optic cables running to a maximum depth of 300 meters. Those cables form a permanent link to cameras and other monitoring instruments resting on the seafloor, where scores of sensors keep watch over the coastal ocean.

• 4. The Ocean Made Public

  ›

  Images and audio gathered on the seafloor are processed and made available through the VENUS website, open to researchers and to the public alike. The project carries a double goal. It aims to provide information that advances research, and it also invites members of the public to log on and view the ocean up close. Funding comes from the federal and provincial governments of Canada, along with private industry. VENUS was designed to provide continuous observations for 20 to 25 years, a span that turns a single experiment into a generation-long look at the deep.
