Storms will very likely cause the sea ice edge to fluctuate. Low air pressure and below average temperatures in the central and western Ross Sea helped push sea ice outward in the eastern Ross Sea (Figure 2d). In Antarctica, a strong high-pressure area over the Peninsula region with counterclockwise airflow helped push sea ice outward along the northwestern Weddell Sea, where the air temperature was quite low (Figure 2c).

Air temperatures were generally above average in Western Europe and Scandinavia, and below average in eastern Siberia (Figure 2b). The outlook for a few more days is for continued warm conditions and airflow that may cause further contraction of the low-concentration sea ice. brings you the latest images, videos and news from Americas space agency. Yellows and reds indicate higher than average temperatures blues and purples indicate lower than average temperatures.Ĭredit: NSIDC courtesy NOAA Earth System Research Laboratory Physical Sciences Laboratoryįor the first two weeks of September, high air pressure prevailed over northern Siberia, with low pressure over Greenland, which created significant winds along the Eurasian coast (Figure 2a). This plot shows the departure from average air temperature in the Antarctic at the 925 hPa level, in degrees Celsius, for September 1 to 11, 2023. High variability is typical of the sea ice maximum period, and further growth is likely from storms or high winds along the vast circumpolar sea ice edge. The five low maximum sea ice extents for Antarctica include 1986, 2002, 2017, 1989, and 2022. If no further net growth occurs, the sea ice maximum will be below 17 million square kilometers (6.56 million square miles) for the first time in the satellite record, and about one million square kilometers (386,000 square miles) below the previous record low maximum of 1986. However, growth slowed after September 8. Much of this expansion occurred in the northeastern Ross Sea and along the Weddell Sea ice front (Figure 1d). Ice blocks the western end of the Parry Channel near M’Clure Strait, but the ice edge has pulled away from the coast in recent days and it appears that there is a narrow ice-free region along the northwest coast of Banks Island.Īntarctic sea ice grew at a much faster-than-average pace through the first eight days of September, increasing at 65,000 square kilometers (25,000 square miles) per day relative to the 1981 to 2010 average rate of 25,000 square kilometers (9,700 square miles) per day (Figure 1c). Both passages of the Northwest Passage are largely clear of ice at the resolution of passive microwave satellite data, but likely have patchy ice remaining. On the Pacific side, the Beaufort and Chukchi Seas have very little sea ice remaining on the Atlantic side, both the Svalbard archipelago and Franz Josef Land are largely ice free (Figure 1a). A few large areas of open water are present between several areas of higher-concentration sea ice. Retreat of Arctic sea ice cover has been primarily in the central Arctic region north of the Laptev and East Siberian Seas in an area of low sea ice concentration (Figure 1a). About the dataĬredit: National Snow and Ice Data Center The orange line shows the 1981 to 2010 average extent for that day. Antarctic sea ice extent for Septemwas 16.94 million square kilometers (6.54 million square miles). And there’s a happy ending, as the logo made a triumphant return on the side of the SpaceX Crew Dragon launched at the end of May, as well as on the spacesuits of astronauts Robert Behnken and Douglas Hurley.Figure 1d. A simple, timeless graphic, the Worm conjured up both far futurism and the all-embracing sophistication of a huge, benevolent corporate identity. ‘The Worm’ traces the application of the snaking logo that was the subject of the original 1974 manual, all the way up to its eventual banishment in the early 90s. Now as a follow-up to the reprint, Standards Manual are creating another showcase trawl through the NASA archive. Reed and Smyth were long-time admirers of the golden age of graphic design standards manuals, back when these were the corporate equivalents of holy tablets, and NASA’s was one of the best. The design industry still loved it though and in 2015 the GSM was given a lavish reprint back in 2015 by Standards Manual, a publishing house set up by Jesse Reed and Hamish Smyth from New York design agency Order. Danne and Blackburn’s meticulous guide to how the logo, typography and graphic sensibility should be applied across everything from confidential memos to minibuses and, of course, spaceships, wasn’t enthusiastically followed.
