Sensors, science and sea change: tackling ocean acidification together

Experts met at Solomon Islands National University to learn hands-on monitoring techniques for ocean acidification.

In September, scientists from across the Pacific gathered at Solomon Islands National University to learn hands-on techniques for monitoring ocean acidification—a growing concern for marine ecosystems and coastal communities. 

Participants received training on how to use specialised tools like pH sensors and the “GOA-ON in-a-box” kit, which tracks changes in ocean chemistry. The workshop wrapped up with the Solomon Islands team successfully deploying their sensor and collecting their first ocean acidification measurements. 

The training was led by experts from the Pacific Community (SPC), Sunburst Sensors, The Ocean Foundation, University of Otago, and Earth Sciences NZ, and was made possible with the support through the Pacific Islands Ocean Acidification Centre

Following the workshop, researchers shared their findings and future plans at the Pacific Island Ocean Conference, contributing to three dedicated Ocean Acidification Dialogue sessions. Pacific researchers presented on their ocean acidification measurements to date and their plans for future monitoring programs and experiments.
