World Ice Coverage Map

The plots and color-coded maps are chosen to provide information about the current state of the sea ice cover and how the most current daily data available compare with the record lows and record highs for the same date during the satellite era. Sea ice concentration is the percent areal coverage of ice within the data element (grid cell). To view daily maps from previous years, click the Archive button to the right of your format of interest. Note that images are numbered with the year followed by the Julian Date, essentially counting the number of days of the year from January 1 (Julian date = 001) to December 31 (Julian date = 365). Right-click any image to download it. Hemisphere Snow Coverage Maps. The cryosphere which are areas covered by ice, snow, glaciers, or permafrost is an extremely dynamic part of our global system. Changes in seasons & climate bring great changes to the Earth's cryosphere. Infrared (IR) and microwave data from multiple satellites including NOAAs GOES Imager and POES AVHRR, US Air. The graph above shows Arctic sea ice extent as of April 2, 2024, along with daily ice extent data for four previous years and the record low year.

Sea Ice Highs and Lows - NASA Earth Observatory - 2023 to 2024 is shown in blue, 2022 to 2023 in green, 2021 to 2022 in orange, 2020 to 2021 in brown, 2019 to 2020 in magenta, and 2011 to 2012 in dashed brown. The 1981 to 2010 median is in dark gray. The Interactive Multisensor Snow and Ice Mapping System (IMS) daily analysis of snow and ice produces a series of charts the cover specific regions in the Northern Hemisphere along with a chart covering the entire hemisphere. Arctic Antarctic Great Lakes Mid-Atlantic IMS Snow/Ice. Snow and Ice Charts Data Files Snow Trend Graph Ice Trend Graph. Sea ice extent provided by the National Snow and Ice Data Center (NSIDC) is available from 1979-2024 for the Globe, Northern Hemisphere, and Southern Hemisphere. Snow cover extent provided by the Rutgers University Global Snow Laboratory (GSL) is available from 1967-2024 for the North America + Greenland, Northern Hemisphere, Eurasia, and North America. Sea ice age coverage map for the week before minimum total extent (when age values are incremented to one year older) in (a) 1985, and (b) 2022; (c) extent of multiyear ice (black) and ice >4 years old (red) within the Arctic Ocean for the week of the minimum total extent. 2017: Variability and trends in the Arctic sea ice cover: Results. The November 2022 Antarctic sea ice extent of 15.

Homepage - 06 million square kilometers (5. 81 million square miles) was about 810,000 square kilometers (313,000 square miles) below the 1991-2020 average. This ranks as the fifth-smallest November extent in the 44-year record. Only November 1986, 2016, 2019, and 2021 had smaller sea ice extents. An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves play an important role in slowing the flow of ice from glaciers or ice sheets into the ocean. When ice shelves collapse, research has shown that glaciers accelerate, flowing into the ocean. The left map shows the total melt days for the Antarctic Ice Sheet from November 1 to February 15, 2024, with an up-close map of the Antarctic Peninsula to its right. The graph shows daily melt extent as a percent of the ice sheet for the 2023 to 2024 melt season through February 15, 2024, with the average values and ranges for the 1990 to 2020. Access the maps and data. Monthly-mean values of the ERA-Interim sea-ice cover are interpolated to a regular 1°x1° grid that is used for plotting maps. The ERA-Interim data are defined only for model grid points that are designated as sea or lake points. A much higher resolution is used to define the shorelines used in. The maps on this page represent the most recent snapshots of those annual highs and lows. "The 2020-2021 Arctic data further confirm that the Arctic sea ice coverage is well below what it had been in the 1970s and 1980s," said Claire Parkinson, a sea ice scientist at NASA's Goddard Space Flight Center. The Last Glacial Maximum (LGM), colloquially called the last ice age, was a period in Earth's history that occurred roughly 26,000 to 19,000 years ago. This map by cartographer Perrin Remonté offers a snapshot of the Earth from that time, using data of past sea levels and glaciers from research published in 2009, 2014, and 2021, alongside. Current Ice Cover Conditions Coastwatch and GLSEA. CoastWatch is a nationwide National Oceanic and Atmospheric Administration (NOAA) program within which the Great Lakes Environmental Research Laboratory (GLERL) functions as the Great Lakes regional node.

Northern Hemisphere Snow and Ice. According to NOAA data analyzed by the Rutgers Global Snow Lab, the winter season (December 2020-February 2021), contiguous U. (CONUS) snow cover extent was 74,775 square miles above the 1991-2020 average and ranked 18th highest in the 55-year period of record. Snowfall during the 2020-2021 snow season. Ice Age Map of the World. This map depicts the Earth during the last ice age, specifically the Late Glacial Maximum (roughly 14,000 BCE) when the climate began to warm substantially. With so much of the planet's water tied up in ice, global sea level was more than 400 feet lower than it is today. The artist worked with climatologists and. A map of sea surface temperature changes and glacial extent during the last glacial maximum, according to Climate: Long range Investigation, Mapping, and Prediction, a mapping project conducted by the National Science Foundation in the 1970s and 1980s. The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, was the most recent time during the Last Glacial Period. An online mapmaker has revealed a unique map showing the world as it would have looked 14,000 years ago, when the last ice age was at its harshest. Designers worked with geologists to accurately. Northern Hemisphere Snow and Ice.
