When they built an underground bike parking garage by the station they turned the old bike parking into a new public square. Then they removed motor traffic from the main road & made it a cycleway, with a bus-only road alongside.

🌊 an opportunity to suggest endangered data, I would think
Depth (0 to 300 m) by time (2022 to 2026) plots of temperature, salinity, particulate organic carbon (POC), chlorophyll (CHL_A), oxygen, nitrate, pH at in situ temp/pressure, and computed dissolved inorganic carbon (DIC) for float 5906497 (adopted name Hedy Lamarr).
🌊BGC-Argo float of the month is 5906497 with 4 years under Antarctic sea ice, just popped out. It was adopted by the American School in Jeddah, Saudi Arabia and named “Hedy Lamarr” – the actress who co-invented and patented frequency hopping communications. Named for her science contribution. 1/2

(a) Annual Southern Ocean NPP (Pg C) time series for six remote sensing algorithms: Eppley-VGPM, Behrenfeld-VGPM, Behrenfeld-CbPM, Westberry-CbPM, Lee-AbPM, and Silsbe-CAFE. (b) Long-term NPP trends (Gg C year−1) averaged across the Southern Ocean for the full time series (darker shade) and a jackknife resampling of the full time series (1998–2024) as a moving 20-year record with the mean trends ± the standard deviation reported (lighter shade).
If you’re interested in the productivity of the southern ocean using remote sensing, floats and models - both now and in the future then this is the paper for you! We’re gearing up for an associated field campaign in January!! 🌊

This figure illustrates the conceptual framework of spatiotemporal dynamics in marine ecological stoichiometry for C, N and P, highlighting how their ratios and distributions vary across spatial scales and over time.
#WeekendReading: Liu et al. on how the ratio between carbon, nitrogen, and phosphorus in the oceans has changed over the last fifty years. Redfield seems (as it has been for a while now) an assumption that has to be verified for each case study. 🧪🌊

Heard this one? The City of Barcelona traded 3 lanes of vehicle traffic for an exceptional 4.7km green pedestrian corridor in the heart of the Eixample grid. Businesses sued, & eventually won in court. Then they admitted that they actually like the change.

There was also a 71% drop in air pollution.
