Speaking the language of coral: using machine learning to predict future distributions of reefs

It’s hard to move these days for the number of AI-powered chatbots: including the now-ubiquitous ChatGPT. The possibilities are endless, from replying to emails to looking for recipe inspiration to end your four-day pasta streak. But the algorithms underpinning these bots can also classify information. Take a movie review, for instance: ChatGPT can distinguish between positive or negative feedback.

In my PhD research, I’m using the same algorithmic architecture that underpins these bots—also known as large language models, or LLMs—to classify decades of environmental data. Specifically, I’m asking: given historic and forecasted physical conditions in the ocean, which locations would get a positive review for their long-term ability to support coral and other reef-building organisms?

The deep ocean is closer than you think: scientific research and life at sea

Nick Reynard is a postdoc in the Centre for Climate Repair in Cambridge, working with Ali Mashayek’s research group at the Department of Earth Sciences. Here, Nick recounts his experience of boarding a five-week scientific cruise in search of the deep Antarctic waters that rise in the Madagascar Basin.

WACSWAIN: Time and ice

My last blog about the WACSWAIN project was in February 2020. We had just started the chemical analysis of our 651-metre-long ice core from Skytrain Ice Rise (Antarctica). The theme of this article is time – the first aspect being that a lot of time has since passed. Soon after I wrote last, our labwork was completely shut down by the pandemic, some of the team went back to their families in other countries, and we all learnt what Zoom meetings were.
