This week in the Deep-Sea Round-Up: 🔹️New DOSI resources on the toxicity risks of #DeepSeaMining. 🔹️#DeepSea fishes from Brazil, Antarctic meiofauna, and migrating snail larvae. 🔹️Plus, imposter syndrome in #MarineScience 👉 www.dosi-project.org/dosi-deep-se... 📷 NOAA Ocean Exploration

What does "serious harm" mean for negotiations at #ISA31 For the #DeepSea the answer often becomes visible only once it's irreversible and current monitoring tools aren't built to catch it early. 📄Learn more about the importance of #DeepSea science for these discussions here: buff.ly/593AfgW

The DOSI delegation is working hard on the ground in Jamaica in the second week of #ISA31 Part II. Tomorrow the group will host a side event at #ISA31 exploring the important #DeepOcean science necessary for discussions on the ISA and BBNJ.

Our new policy brief lays out three evidence-based recommendations for #ISA31 1️⃣ Assess toxicity using real biological effects 2️⃣ Develop and validate biomarkers for #DeepSea species 3️⃣ Set precautionary toxicity thresholds 📄 Read the full policy brief here: buff.ly/jFavppr
