For more than two years, researchers on board the French expedition ship Tara sailed through the Pacific, stopping at almost 100 coral reefs to take thousands of water and coral samples. The expedition ended in 2018, and the analysis of the massive amount of data collected has taken five years.

Now, the initial results of the data analysis have been published. The findings should help us to better understand the living conditions of corals, to check their health status and to open up new possibilities for nature conservation. 

Ocean deoxygenation has detrimental repercussions. Fish, crabs and other significant species of marine life that are unable to flee these low oxygen zones may perish as a result. People who depend on them for food and employment may be subsequently impacted by their absence as many of these species are economically significant.

Additionally, there is a negative feedback loop at play: as ocean oxygen levels decline, so does its capacity to absorb carbon dioxide. This may cause global warming to accelerate even further.

According to the WMO projections, there is a 90 percent chance that the El Niño event will persist over the second half of 2023. It is predicted to be at least moderately strong.

El Niño episodes typically last between nine and twelve months and occur every two to seven years on average. It is a naturally occurring climate pattern linked to the warming of the tropical Pacific Ocean's central and eastern ocean surface temperatures.

However, it occurs in a climate that has been altered by human activity.

Entering the exhibition hall on Day One at MIDE 2023 gave me a distinct buzz. Squaring my shoulders in anticipation, I walked past the booths and waved hello to old friends. As I made my way deeper into the hall, I felt a raising sense of excitement. MIDE 2023 was my first overseas dive show since the pandemic, and it appeared to be off to a promising start.
