Happy 25th birthday to the #Argo program! We’re proud to have been part of making this global ocean observing network a success since 1999! Here’s to the next 25! 🥳

||◤ プレスリリース◢|| 海中の“酸素の動き”から“炭素の動き”を解き明かす ―生物による海洋二酸化炭素吸収量の新たな評価― jamstec.go.jp/j/about/press_… #JAMSTEC 地球環境部門 海洋観測研究センターの山口研究員 ＠ryamaguchi017 、纐纈主任研究員らによる研究成果です。 〔発表のポイント〕

📢The biological #carbon pump exports about 7.36 Pg of carbon globally per year from the upper ocean. New paper by Ryohei Yamaguchi et al.! JAMSTEC 海洋研究開発機構 ＼海と地球の研究所／ 📎nature.com/commsenv/resea…

Jupyter Agents - LLMs running data analysis directly in a notebook! The agent can load data, execute code, plot results and following your guidance and ideas! A very natural way to collaborate with an LLM over data and it's just scratching the surface of what's possible soon!

Instead of listing my publications, as the year draws to an end, I want to put pressure on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research

“the entire Argo array consumes about 120 watts — that is about 60% of the power used by a single Sony PlayStation 5 when gaming.” noaa.gov/news/argo-crow…

Excited to share our new paper "Unlocking Southern Ocean Under-Ice Seasonality with a New Monthly Climatology" in JGR Oceans!🌊 🌟Highlights: 1️⃣ Best data fidelity w/ minimal interp. misfit 2️⃣ New insights into subsurface seasonality 3️⃣ Improved access to valuable under-ice obs

こちらの記事、担当しました。直接大気からではなく、なぜ海洋？ーというと、海水中には大気中に存在する量の50倍もの炭素が蓄えられているので、効率よく除去できると考えられているようです。

Just passed the halfway point of the R/V Mirai GO-SHIP P04W cruise!!

観測も後半になって、帰港までの時間が惜しくなってきました😬 今日は、少しでも早く採水を終えるよう、たくさんの研究者・技術者に協力してもらいました🙌✨ #みらいtheFINAL #みらい #JAMSTEC #研究航海

At the last CTD station, a rainbow celebrated the end of our long journey! #GO_SHIP #P04W

We're going to try to unravel the mysteries of the hottest ocean anomaly in the Kuroshio Extension!!
