finally... Our new paper has been published from @CommsEarth !! Please check the new observational constraint on the global biological carbon pump based on dissolved oxygen budget 🌊 nature.com/articles/s4324…

Pleased to share our new paper titled “Emerging outflow of not-so-dense shelf water from an East Antarctic polynya” @CommsEarth 🌏🌊🌱 Inspired by a surprising signal of AABW formation from the polynya, captured in the 2024 MISO cruise. Accessible here: nature.com/articles/s4324…

@KaiheZak 拝聴しました！面白かったです！

怒涛の3日間が終わった… 何かイキり野郎と思われてそうで怖い 許してください何でもしますから！

Our new paper is now available in AGU Advances: Okajima, Kosaka, Miyasaka, Ito, 2025 - AGU Advances Unprecedented Marine Heatwave Significantly Exacerbated the Record‐Breaking 2023 East Asian Summer Heatwave agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

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

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

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

😂

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

@KaiheZak いいですね！こちらは某IIに期待😇

@ryamaguchi017 ムーンプールもあるので、昨年乗ったInvestigatorのさらに倍はあろうかと 若干持て余してます(瓶を運ぶ距離が長い)

日常(採水中) ワイは奥でDOやってる #DMV #DenmanMarine

Dr. Hayashida (APL Researcher) et al. published a paper, accessing the performance of Biogeochemical Argo floats in measuring chlorophyll-a concentrations and their spatiotemporal structures via comparison with satellite and shipboard data. link.springer.com/article/10.100…

相模湾で採集した珪藻(コアミケイソウの仲間)です。 幾何学模様が面白いです

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。

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

“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…

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
