This analysis was made possible through the development of a statistically-based, custom pipeline, enabling authors to classify ~19 million OBIS records as either benthic or pelagic datasets. We’re thrilled to say that both the final datasets, and the code to recreate them are #OpenAccess too!

So, if we are to prioritise ocean biodiversity data collection to deliver a sustainable ocean, where should we focus?

These gaps matter 🌍 – biodiversity data fuels conservation 🐢, climate models 🌡️, and ocean planning 🌊. But if your model is trained on fish 🐟 in shallow waters, it probably won’t help protect deep-sea invertebrates 🪸 3,000 meters below. We’re building global policy on patchy foundations 🧱❓.

And the pelagic data distribution is no better…

Key findings from the benthic dataset show just how little of the seafloor below 30 m we’ve sampled:

Despite decades of exploration, we still can't fully answer “Where is marine life found, and why?”. A new study in @commsearth.nature.com shows just how skewed our ocean data really is…

🔍Mapping the Gaps: New global study reveals huge biases in benthic & pelagic biodiversity data – but what does this mean for science & conservation, & how can we address it?

Deep Hotspots of Biodiversity | Canyons, Vents, and Seeps of the Chile Margin Join the #ChileanMargin2024 expedition team aboard Research Vessel Falkor (too) as they explore diverse underwater ecosystems along Chile's coast. They are exploring methane seeps and submarine canyons, both different hidden biodiversity hotspots deep within the ocean. Using advanced technology, including remotely operated vehicles (ROVs), core samplers, and methane detectors, scientists document rare sights like gas bubble streams and thriving microbial life—organisms that rely on chemosynthesis, rather than sunlight, for survival. This groundbreaking expedition provides insights into the ocean's role in climate change, carbon capture, and our planet’s complex ecological connections.

Dive into the #ChileMargin24 expedition in this video by @schmidtocean.bsky.social! From uncharted canyons to deep-sea biodiversity, see the discoveries firsthand 🔬🐙.
