International sensors at Endeavour hot vents

OCEAN NETWORKS CANADA MEDIA FACTSHEET
 

This Ocean Networks Canada factsheet is to provide correct information related to recent media reports. Ocean Networks Canada is an initiative of the University of Victoria.

  • Ocean Networks Canada recently installed very short-range (5m) oceanographic sensors to measure chemical properties of water and rocks in the deep ocean (more than 2,000m) at the Endeavour hydrothermal vents as part of this past summer’s annual maintenance expedition.
  • The equipment was built by researchers at China’s Institute of Deep-Sea Science and Engineering (IDSSE).
  • The hardware takes measurements within a range of less...

From Cosmos to Core: Wiring the Abyss Expedition 2018

The deep sea holds answers to many scientific questions about the origin of life on Earth, our changing ocean, and even outer space. This year, Ocean Networks Canada’s (ONC) annual Wiring the Abyss expedition expanded infrastructure to monitor both deep sea and deep space⎯from the cosmos to the core⎯reaching new milestones for our offshore observatory in the northeast Pacific Ocean.

ONC’s annual maintenance expeditions allow for instrumentation to be added, maintained, and recovered, live streaming these deep sea operations in real time so everyone can #knowtheocean. Wiring the Abyss Leg 1, aboard Canadian Coast Guard ship John P. Tully,...

In July 2018, a team of 48 scientists, engineers, communicators, and crew aboard the exploration vessel Nautilus conducted around-the-clock operations to maintain and expand instrumentation on Ocean Networks Canada’s cabled observing systems off Canada’s west coast.

Highlights include an exciting new neutrino experiment at Cascadia Basin to determine whether this location can support a large-scale neutrino detector array in the future; expanded instrumentation at Endeavour, including new sensors and cameras to improve our understanding of this dynamic hydrothermal vent ecosystem; installation of the final earthquake early warning seafloor sensors at Cascadia Basin, Barkley Canyon, and Clayoquot...

Following the successful completion of Wiring the Abyss Leg 1 aboard Canadian Coast Guard ship (CCGS) John P. Tully, the Ocean Networks Canada (ONC) team are busy preparing for Leg 2 of our annual offshore expedition to install and improve cabled observatory infrastructure, 21 July - 4 August. The upcoming 2-week expedition aboard exploration vessel (E/V) Nautilus will complete many of the installations deployed aboard CCGS Tully (Figure 1).

Ocean Networks Canada’s (ONC) Expedition 2016: Wiring the Abyss returned to port on June 25 after 40 days at sea off the west coast of Canada. This ambitious undertaking involved 149 people aboard three ships, and included three remotely operated vehicles (ROV) making 44 dives to deploy, maintain and recover 180 instruments and lay 18 km of fibre-optic cable. The dynamic 24/7 operations engaged viewers across the world via live stream and featured regular Q&A with scientists, educators and engineers.

Thompson Expedition Summary: June 2013

​

​

We are back in the office after nearly 3 weeks at sea aboard the University of Washington’s R/V Thompson. The team followed the Operations Plan that was set out over the last 6 months and achieved most of the planned goals. The weather co-operated perfectly for dive operations, resulting in no weather downtime. The remotely operated vehicle (ROV) crew ensured that there was as little vehicle downtime as possible and was quick to resolve any problems subsea and on deck.

Endeavour's Complex Environment

The Endeavour segment of the Juan de Fuca ridge is home to one of the deepest (2200 – 2400 m) collections of experiments in the NEPTUNE Observatory. This deep-sea mountain ridge is located approximately 300 km off the British Columbian coast along the spreading crustal boundary between the Juan de Fuca and Pacific tectonic plates. The Endeavour site presents an elaborate network of seafloor structures where active hydro-geothermal venting creates highly variable local temperatures throughout the system. Due to its dynamic characteristics, Endeavour offers a rare opportunity to study globally significant chemical, biological and geological processes unique to these otherworldly deep-sea environments.
