Led by PRL student Deepak Rai, we recently had a new paper out showing that the Oxygen Minimum Zone in the Arabian Sea *expanded* in size during the last glacial cycle @arvindocean.bsky.social agupubs.onlinelibrary.wiley.com/doi/full/10....

One of the dumbest claims from climate deniers is that ocean warming is from deep-sea volcanoes. ³He in the deep ocean comes from volcanoes, and if heat and carbon did too, the ocean temp and carbon distribution would be similar to ³He (they’re not). agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Ocean waters are aging? What? Yes: oceanographers call 'age' the time since deep ocean water was last in touch with the atmosphere. It is a measure of 'ventilation', deep vertical overturning of the ocean. Data show this process is slowing: #AMOC slowdown. Bad news. 🌊 www.geomar.de/en/news/arti...

JGR–Oceans is seeking Editors and Associate Editors across all areas of ocean science—with particular interest in expertise related to Lagrangian dynamics, ocean color remote sensing, air–sea coupling, sea level, circulation theory, and ocean change. Join us in shaping the future of ocean research!

Wrapped up an inspiring week at #ICP15 🌊 It was a privilege to share my research and exchange ideas with such an incredible community of paleoceanographers. And also, thrilled to receive honourable mention for the poster. Grateful to @arvindocean.bsky.social for the guidance 🌊 🌏

#ICP15 presents first panel discussion on #Biogeochemistry and #Climate 🙏🏼 @chalkyoceans.bsky.social @jfarmersalmanac.bsky.social @eleniwater.bsky.social @seavdavis.bsky.social @alexauderset.bsky.social Arvind Singh and conveyors Adina Paytan and Harshit Singh Along with stage volunteers 🙏🏼

Happening now at #ICP15: Arvind Singh from Physical Research Labs, Ahmedabad, talks about #iodine (I/Ca) measurements in planktic #foraminifera from Arabian Sea #sediments recording glacial-era expansion of the oxygen minimum zone.

New paper alert 🚨🚨 Here we posit a non-linear relationship between Indian Summer #Monsoon (ISM) intensity & marine productivity in the Bay of #Bengal: extremely weak & strong #ISM states of the last 22,000 yrs were *both* associated with sharp disruptions to primary production! (1/6) rdcu.be/ejJD2

⚒️ Article: Changes in terrestrial runoff into the Bay of Bengal during both extremely weak and strong Indian summer monsoon phases since the Last Glacial Maximum caused a collapse in marine primary production linked to increased stratification www.nature.com/articles/s41...

The AGU will always stand by and represent the scientific community 🧬⚛️🌊🔭🔬 Addressing global Earth Science challenges requires an equitable, diverse, and inclusive scholarly community where researchers must be freely able to discuss their research. agupubs.onlinelibrary.wiley.com/doi/full/10....

Some defiance for science! 🌊🌏🧪 @agu.org We affirm our commitment to publishing evidence-based Earth and space sciences that is free from political interference We will continue to foster a diverse, equitable, and inclusive scientific community because it improves the quality of science

🔬Science must remain free from political interference. As Editors-in-Chief of AGU Publications, we reaffirm our commitment to rigorous, independent, and inclusive Earth and space science research. A diverse scientific community strengthens discovery and solutions for society.

#WeekendReading: Hoogakker (and 67 other people) go into the current state of low-oxygen proxies currently in use in paleoceanography. It's a small book (95 pages), more than a paper, and covers a lot. 🧪⚒️ bg.copernicus.org/articles/22/...

The Mauna Loa CO₂ record is the most iconic time series in the environmental sciences. Trump and his enablers are trying to kill it.

🚨 #NOAA is essential for weather forecasting, climate research, and public safety. AGU stands with the scientific community in urging Congress to protect and strengthen NOAA, not dismantle it. Our economy, environment, and safety depend on it.

🌊 Not sure how to resist Trump as our institutions are bullied and silenced by threats of federal defunding? Join AGU. Together we are strong and can speak truth to power on science and equity issues.

Opting out will make climate change more of a threat to US citizens! “The world’s largest community of climate scientists urges the Trump administration to immediately renew U.S. federal commitment to climate science, including the restoration of data, personnel, grants and collaborations.”

🌊 Dear NSF and NOAA colleagues, Your work matters. Many of you have sacrificed personal gain and scientific freedoms to serve the public good. Thank you! Your mission protects lives and protects nature, including the most vulnerable people and places suffering the fall out of anthropogenic change.

"In these times, it is crucial to reaffirm our commitment to the values that unite us: the unbiased pursuit of scientific inquiry, respectful collaboration across diverse backgrounds, and the unwavering affirmation of basic human decency and integrity."

Science is not about knowing and understanding, it is about seeking knowledge and understanding. Hence, we scientists must push our human selves to get comfortable with ignorance and uncertainty. This requires compassion, for ourselves and for our colleagues.

Micro/nanonutrient limitation, it's not just iron 🧪🌊

With an exponential growth in publications, are we advancing ocean science faster than ever before? As EiC @jgroceans.bsky.social I see better analyses on bigger data, but often at the cost of reflection on previous studies and of articulation of the most important gaps in our understanding.
