Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. What's hot in the Desogestrel and Ethinyl Estradiol Tablets (Pimtrea)- Multum around climate and sea ice and what are scientists talking about now.

When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. On September 15, Arctic sea ice likely reached its annual minimum extent of 3. The minimum ice extent is Desogestrel and Ethinyl Estradiol Tablets (Pimtrea)- Multum second lowest in the 42-year-old satellite record, reinforcing the long-term downward trend in Arctic ice Desogestrel and Ethinyl Estradiol Tablets (Pimtrea)- Multum. Sea ice extent will now begin its seasonal increase through autumn and winter.

In the Antarctic, sea ice extent is now well above average and within the range of the ten largest ice extents on record, underscoring its high year-to-year variability.

The annual maximum for Antarctic sea ice typically occurs in late September or early October. Please note that this is a preliminary announcement. Changing winds or late-season melt could still reduce the Arctic ice extent, as happened in 2005 and 2010. NSIDC scientists will release a full analysis of the Arctic melt season, and discuss the Antarctic winter sea ice growth, in early October.

Arctic sea ice extent for September 15, 2020 was 3. The orange line shows the 1981 to 2010 average extent for that day.

Sea Ice Index data. About the dataCredit: National Snow and Ice Data CenterHigh-resolution imageFigure 1b. The map above compares the 2012 Arctic sea ice minimum, reached on September 17, with the 2020 Arctic sea ice minimum, reached on September 15. Light blue shading flesh eating fungus the region where ice occurred in both 2012 and 2020, while white and medium blue areas show ice cover unique to 2012 and to 2020, respectively.

About the dataCredit: National Snow and Ice Data CenterHigh-resolution imageA sharp decline of Arctic sea ice at the beginning of September dropped the extent below 4.

After September 8, daily melt began leveling out, reaching its seasonal minimum extent of 3. This appears to be the lowest extent of the year.

In response to the setting sun and falling temperatures, ice extent will begin increasing through autumn and winter. However, a shift in wind patterns or a period of late season melt could still push the ice extent lower. Compared to 2012, the minimum extent this year valtrex 500mg more ice in the Beaufort Sea, but somewhat less ice in the Laptev and East Greenland Sea regions (Figure 1b). The minimum extent was reached one day later than the 1981 to 2010 median minimum date of September 14.

The interquartile range of minimum dates is September 11 to September 19. The graph above shows Arctic sea ice extent on September 15, 2020, along with several other recent years and the record minimum set in 2012.

The 1981 to 2010 median is in dark gray. The gray areas around the median line show the interquartile and interdecile ranges of the data.

On the right, the average (square) and range of highest and lowest extents at the minimum for each period are given. It is also 2. The 42-minimum-extent values in the satellite record can be broken down into three 14-year periods. Most notably, minimum extents in the last 14 years of the time series are the lowest lexi johnson in the 42-year record (Figure 2b). All three periods show a downward trend.

The middle period, 1993 to 2006, shows the steepest downward trend of 13. The earliest period, 1979 to 1992, has a downward trend of 6. The overall, downward trend in the minimum extent from 1979 to 2020 is 13. Values within 40,000 square kilometers (15,000 square miles) are Desogestrel and Ethinyl Estradiol Tablets (Pimtrea)- Multum tied.

Hope 2019 value has changed from 4. A collaborative network of scientists and stakeholders to advance research on sea ice prediction and communicate sea ice knowledge and tools.

Совершенно верно! Именно так.
