Thank you to our DOSI Delegation who participated in #ISA31 Part II over the past two weeks. The group raised awareness of deep-sea science in #DeepSeaMining discussions and delivered a side event exploring the science need for the ISA and #BBNJ 📷 Earth Negotiations Bulletin
The draft #ISA guidelines ask contractors to show deep-sea mining won't cause "serious harm" but our new Policy Brief shares the scientific tools to prove (or disprove) that don't fully exist yet. 📄Read the science and our recommendations here: buff.ly/jFavppr #ISA31 #DeepSeaMining
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
Deep-sea grenadier fish sampled from the Clarion-Clipperton Zone already carry mercury and cadmium levels that would raise alarm bells in coastal waters. 📄 Learn why this science is important to the current #ISA31 discussions in our DOSI Info Sheet: buff.ly/593AfgW
A new DOSI Policy Brief is available as delegates convene in Kingston Jamaica for #ISA31 Science shows us that the ecological footprint of #DeepSeaMining doesn't stop at the contract boundary. 📄 Read the full brief here: buff.ly/jFavppr
