In 1987, Broecker introduced the ocean’s “conveyor belt” metaphor, showing how circulation can trigger abrupt climate shifts. 🌊 Read more: https://oceanofisica.ulpgc.es/efemeride/broeckers-conveyor-b

Breaking News! Code: y-axis alert. Nino 3.4 SST is now up to 3.63 SD above the 1991-2020 baseline, about 1-in-7000 in the absence of anthropogenic warming. There's not enough room in a single post to express just how crazy this is. Please read: climatecasino.substack.com/p/some-monst...

The Longitude Act was passed #otd in 1714, offering a prize for a reliable way to measure longitude at sea. This breakthrough made the ocean measurable—enabling modern physical oceanography. 🌊 Read more: https://oceanofisica.ulpgc.es/

A new round is done! 16 teams are out, 16 remain, and with this smaller crowd the World Cup keeps drifting westward, now sitting in the middle of the Atlantic Ocean. Where will it head next? We'll find out next Tuesday. Until then, enjoy!

Oceanofisica is a space for ocean analysis, but we don't live with our backs turned to current events either. So we put together this video: it simulates the World Cup trophy's journey based on which countries remain in the competition, using their average position as the reference point.

🌍 #otd in 1957, the International Geophysical Year began—30,000+ scientists from 66 countries studied Earth’s oceans, atmosphere, and more during the Cold War. A milestone in global collaboration. Read more: https://oceanofisica.ulpgc

In 1974, the CTD profiler became a standard tool, replacing Nansen bottles with real-time, high-resolution ocean data. 🌊 It transformed how we study ocean structure and still underpins modern sensors. Read more: https://oceanofisica.ulpgc.es/

We know, we live in a changing world. How temperature is evolving is just a measure for that change and how we might be feeling it. Here we have 61 years of changing global temperatures (Data exported from ERA5). #ulpgc #climatechange #oceanography #era5 #temperature

On June 28, 1978, NASA launched Seasat, the first satellite dedicated to oceanography. 🛰️ Its instruments measured sea surface height, wind, temperature, and waves—paving the way for future missions. More here: https://oceanofisica.ul

Georg Wüst was born #otd in 1890. His work on the Meteor expedition transformed oceanography, revealing the Atlantic’s layered deep circulation. 🧵 Read more: https://oceanofisica.ulpgc.es/efemeride/georg-wust

🌊 Our review paper is out! "One hundred years of progress in understanding the dynamics of Eastern Boundary Upwelling Systems" is now published in @ICESJournalofMarineScience 👉 doi.org/10.1093/icesjms/fsag107 🧵 A thread on what we did and why it matters: 🧪

In 1955, the first Swallow float was deployed—a neutrally buoyant drifter that tracked subsurface currents directly, revolutionizing oceanography. 🌊 Read more: https://oceanofisica.ulpgc.es/efemeride/first-swallow-float #

🌊 World Oceans Day, June 8. Oceans cover >70% of our planet, sustaining life and climate. Proposed in 1992, recognized by the UN in 2008. A day to reflect on their protection. Read more: https://oceanofisica.ulpg

🌊 @globaloceanbgc.bsky.social GO-BGC float of the month. El Niño is coming. The 2023/24 event is clear in the @bgc-argo.bsky.social record. The white, 29C contour outlines anomalies in pCO2, NO3, chlorophyll and particulate organic carbon. Those white contours are emerging again. Stay tuned.

On this day in 1894, Fridtjof Nansen introduced his water-sampling bottle, revolutionizing oceanography by enabling precise depth-specific samples and temperature readings. Its design later inspired the Niskin bottle, still used today. 🌊 Read more: https://oceanofisica

The homepage of my Physical Oceanography website has a section called "Oceanography Today" that automatically aggregates posts from oceanographic institutions on Bluesky. It updates on its own, in real time. #Oceanography #BlueskyLists

On this day in 1874, Vagn Walfrid Ekman was born. His work on the Ekman Spiral explained how wind and Earth’s rotation shape ocean currents. 🌊 Dive into his legacy: https://oceanofisica.ulpgc.es/efemeride/birth-vagn-walfrid-ekman-pioneering-oceanographer #otd

🌊 What does the ocean look like today? Every day, our system automatically publishes global ocean maps in near real time: 🌡️ Sea Surface Temperature 🧂 Sea Surface Salinity 📈 Sea Level Anomaly 🟢 Chlorophyll-a concentration 🌀 Current speed 👉 oceanofisica.ulpgc.es/oceanlive #Oceanography #ULPGC

Confused by media reports about the tipping point of the Atlantic Ocean's overturning circulation #AMOC? Carbon Brief has an excellent explainer about a serious risk which might strongly impact your future: 🌊 interactive.carbonbrief.org/amoc-explain...

AMOC: Is global warming tipping key Atlantic ocean currents towards ‘collapse’?

The AMOC is under threat from human-caused climate change, as warming seas, melting ice and increased rainfall upset the temperature and salt balance of the North Atlantic.

On this day in 1927, the NAS commissioned Henry B. Bigelow to write "Oceanography," a landmark report that united marine science as a cohesive field. 🌊 Read more: https://oceanofisica.ulpgc.es/efemeride/commissioning-henry-b-bigelows-oceanography-comprehensive-survey-marine-science

2025–26 points to be an exceptionally wet hydrological year in Gran Canaria 🌧️ Accumulated rainfall at Gran Canaria airport since October 1st has reached 212.9 mm, nearly double the historical median and approaching the 95th percentile of the 1951–2024 record.

🌍 Happy Earth Day!! Earth is likely a misnamed planet... Should it be called Ocean? The ocean drives our climate and absorbs most of the heat from global warming... and occupies 71% of its surface. To understand Earth, we need to understand the ocean. #WorldEarthDay #ULPGC
