The School of Marine Science & Policy at the University of Delaware is hiring! We are looking for a talented Coastal Physical Oceanographer to join us.

More information is available here, and don't hesitate to reach out if you have any questions.

Tenure-Track Assistant Professor in Coastal Physical Oceanography School of Marine Science and Policy, College of Earth, Ocean and Environment University of Delaware Newark, DE Starting Date: 2026-2027 academic year The School of Marine Science and Policy (SMSP) seeks to hire a tenure-track coastal physical oceanographer with research interests in estuaries, continental shelves, or the interface between coastal and open oceans. We seek candidates with research interests from any area of coastal physical oceanography, including a broad set of processes and varying scales: turbulence and mixing, meso- and submesoscale dynamics, boundary layers, shelf-wide circulation and property budgets, and the impact of climate on the coastal ocean, among others. Applications of candidates that integrate field observations, theory, or numerical modeling are welcome.

Was there any coverage of the recent record warmth in both the Arctic and Antarctic? Multiple global datasets now confirm these records, and I think it's really quite striking.

Here's some very quick plots showing NOAAGlobalTempv6 data from October too. And see my earlier posts.
A line graph shows the time series of Arctic mean surface temperature anomalies for each October from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly in October 2025 was 3.78°C for this region. Anomalies are computed relative to a 1910-2000 climate baseline. All data is from NOAA/NESDIS/NCEI NOAAGlobalTemp v6.0.0 on this graphic. A line graph shows the time series of Antarctic mean surface temperature anomalies for each October from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly in October 2025 was 1.43°C for this region. Anomalies are computed relative to a 1910-2000 climate baseline. All data is from NOAA/NESDIS/NCEI NOAAGlobalTemp v6.0.0 on this graphic.

📢Global Carbon Budget 2025📢

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.

The key findings are covered in two reports this year:
* ESSDD (preprint): essd.copernicus.org/preprints/es...
* Nature: www.nature.com/articles/s41...

Emerging evidence shows the Antarctic is entering an abrupt regime shift: record-low sea ice, slowing overturning circulation, and rising risk of West Antarctic Ice Sheet tipping

Interacting feedbacks may trigger global cascades, staying near 1.5 °C is critical

The fate of silicon in the ocean is something we surprisingly still trying to wrap our heads around. Part of it is integrated into the shells of marine organisms (e.g., diatoms), but when they die, some dissolves back, and some apparently turn into clay. 🧪🌊

Representative SEM images and EDX elemental maps of reacted bSi after 40 days. (A) 0Fe(II) + bSi, (B)1000Fe(II) + bSi, (C)1000Fe(II) + bSi + Al, and the morphology and EDX spectra of neoformed phases in 1000Fe(II) + bSi + Al (D) and 1000Fe(II) + bSi + FeAl (E) treatments. No changes in morphology were observed in 0 μM Fe(II) treatment (A), whereas bSi were extensively altered and elemental association of Fe, Si, and O were observed in [(B) and (C)]. Flake-shaped rosette clusters of authigenic phases were observed in [(D) and (E)], with both phase rich in Fe, Si, Al, and Mg with small amounts of Ca. Dashed areas in [(D) and (E)] show zoomed view with EDX spectra taken at the cross point.
