Scope

Deep Blue League analysed public sentiment on social media in the wake of Donald Trump’s executive order on 24 April 2025, which aimed to fast-track deep sea mining projects under a dormant and contested United States regulatory framework.

The analysis spanned 24 April 2025 to the date of publication, and used AI to interpret trends across X (formerly Twitter), Reddit, Facebook, LinkedIn, and Bluesky.


Social media landscape

While Statista data shows other platforms with more global users, the five selected channels are better suited to real-time content and complex debate, making them more appropriate for gauging sentiment around deep sea mining.

By 2040 the demand for critical minerals is expected to be more than… | Roland Plett
By 2040 the demand for critical minerals is expected to be more than triple what it is today. Does this mean we need to figure out a sustainable way to mine our sea floors? This question has led me into a content creation binge that you'll see more from in the weeks to come. I recorded some of my initial thoughts in this Monday Mining Muse. I'd love to hear your thoughts in the comments. YouTube: https://lnkd.in/gKh2NP_k (Show notes and references)
