In Beijing for the CLIVAR meeting on detecting ocean oxygen changes in a warming climate. Delivered my talk this morning (do shifts in spatial sampling influence the trend in oxygen decline?). Went well.

This kind of smart, walkable, mixed-use development is illegal to build these days.

Just seen somebody suggest there's no guidebook available that will describe what to expect on various cruise liners.
I beg to differ...

Huh, something I'll need to look into in my oxygen atlas...
Hot off the (e-)press, a study in Science led by Nic Duprey showing that the variability of the world's largest Oxygen Deficient Zone over the last 80 years is tightly linked to Pacific Decadal Variability: www.science.org/doi/10.1126/...
Decadal oscillations in the ocean’s largest oxygen-deficient zone
The impact of global warming on the ocean’s oxygen-deficient zones (ODZs) is uncertain, partly because of a lack of data on past changes. We report monthly resolved records of coral skeleton–bound nit...

#OTD 1949 #NavalHistory HMS Implacable was scuttled at St Catherine's Deep, off the Isle of Wight.
Formerly the French third-rate Duguay-Trouin (74), she fought at Trafalgar in 1805 and was captured by the Royal Navy later that year at Cape Ortegal, by a fleet under Sir Richard Strachan

Lagrangian particle tracking (to physical oceanographers) or larval modelling (to "fish botherers"). Any guess which species this is?
