NOC sensors to collect critical data from unseen ocean depths

LinkedIn +

The Blue Ocean Research Alliance (BORA), a partnership between the National Oceanography Centre (NOC) and Subsea7, has launched the first in a series of remotely operated vehicles (ROVs) that contain the new BORAbox ocean monitoring sensor suite.

The sensors are currently collecting data on Subsea7 vessels in the South Atlantic, Brazil, and further launches are planned in Norway and further afield including Australia.

BORAbox, an integrated suite of sensors developed by NOC scientists, will measure several parameters to establish the total alkalinity – a measure of the water’s ability to resist a reduction in its pH level. The information gathered will feed into a global understanding of climate change and its impact on the oceans. As a result, the research will also be used to better predict how the oceans and weather systems will react over the coming decades.

Dr Carla Sands, BORA project manager from NOC, said, “This launch is an exciting moment for ocean research. So much of our ocean remains unexplored. This new technology allows us to dramatically increase our monitoring capabilities in areas of the ocean. By studying pH and alkalinity, we can dramatically inform future studies and help authorities around the world mitigate much more effectively the effects of climate change in the ocean.”

BORAbox will begin by monitoring temperature, salinity, depth and the carbonate system. These are vital measurements in helping to monitor the well-being of the oceans. The data will be analyzed by scientists where it will then be used to support further ocean observation studies and help to shape major global ocean health assessments. As the project expands with more launches from other locations, the new data represents a significant upgrade on what is presently available. Current observations may only span short distances and can often be out of date by the time it is accessible.

Sands added, “The need to have up-to-date information is critical given the dramatic increase in CO₂ currently being added to the atmosphere. Around 25% of man-made CO₂ such as fossil fuel burning gets absorbed by the ocean which helps to regulate CO₂ in the atmosphere. However, too much CO₂ in the ocean can cause it to acidify and damage plant and animal habitats.”

Liz James, Subsea7’s group environmental director, said, “Subsea7 is excited and committed to this dynamic and innovative relationship, bringing science and industry together, having now installed a BORAbox on our vessel, Seven Pacific, working in Brazil. We will be fitting further BORAboxes to our global fleet, enabling greater ocean access to scientific research and advancing global knowledge for the benefit of understanding the ocean, biodiversity and the impact from our operations on the environment.”
