Deep water underneath the Thwaites ice shelf front is lighter than water outside the ice shelf. (A) Map of trough T3 showing the AUV path color coded by latitude. Shaded region indicates the ice shelf front, and black contours are depth contours. (B) Conservative temperature θ (in degrees Celsius) versus absolute salinity SA (in grams per kilogram) for the AUV data points shown in (A), colors as in (A). Contours show potential density (9) relative to 900 m, and blue arrow indicates isopycnal mixing, i.e., water that has the same density but different temperatures and salinities. Green circles in (A) and (B) show the dense saline deep water found in trough T3 discussed in the main text. (C) Absolute salinity SA (in grams per kilogram) as a function of depth for the AUV data in trough T3 and the CTD data (colors indicate station as in Fig. 3). (D) Potential density (in kilograms per cubic meter) as a function of depth for the AUV data in trough T3 and the CTD data (colors indicate station as in Figs. 3 and 4). Red and blue arrows indicate the two deep water masses discussed in the main text from Pine Island Bay and Thwaites Trough. Dissolved oxygen versus θ and SA is shown in fig. S6.

Exploration of ocean currents beneath the “Doomsday Glacier” by an autonomous underwater vehicle – Net melting of 75 cubic km of ice per year means “the glacier is not stable over time”

9 April 2021 (University of Gothenburg) – For the first time, researchers have been able to obtain data from underneath Thwaites Glacier, also known as the “Doomsday Glacier”. They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow. With the […]

Sea level rise is killing trees along the Atlantic coast, creating “ghost forests” that are visible from space

By Emily Ury 6 April 2021 (The Conversation) – Trekking out to my research sites near North Carolina’s Alligator River National Wildlife Refuge, I slog through knee-deep water on a section of trail that is completely submerged. Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in […]

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020 – Carbon dioxide levels now higher than any time in past 3.6 million years – Largest annual methane increase ever recorded

7 April 2021 (NOAA) – Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was […]

Top 10 accounts by tweets, likes, and retweets in tweets mentioning “vaccines” or “vaccinations” between 9 November 2020 and 9 February 2021. The fact that the Russian Embassy in Mexico received the fifth most likes and retweets is remarkable given that the embassy only posted 46 tweets mentioning vaccines during the studied period. On a per-tweet basis, the embassy’s vaccine-related tweets received the most engagement of any monitored account—roughly 795 likes and 374 retweets per post—far more than state media accounts with 100 times more followers. Likely buoyed by its vaccine messaging, the @embrusiamexico account saw the third largest percent gain in followers (70 percent) among monitored Russian accounts during the studied period.

Covid-19 daily cases per 100,000 population in Brazil, 27 March 2021. On 24 March 2021, Brazil recorded 300,000 Covid-19 deaths, with roughly 125 Brazilians succumbing to the disease every hour. More than a year into the pandemic, deaths in Brazil are at their peak, and highly contagious variants of the coronavirus are sweeping the nation, enabled by political dysfunction, widespread complacency and conspiracy theories. The country, whose leader, President Jair Bolsonaro, has played down the threat of the virus, is now reporting more new cases and deaths per day than any other country in the world.
