The story of this NASA-led satellite bathymetry experiment unfolds through the photography and expedition documents preserved by David Lychenheim, the expedition’s communications engineer. Research done during that expedition determined that in certain conditions Landsat could measure depths up to 22 meters (72 feet), which gave birth to the field of satellite-derived bathymetry. This new technology enabled charts in clear water areas around the world to be revised, helping boats and deep-drafted supertankers avoid running aground on hazardous shoals or seamounts.Music: “Science of Life,” “Moving In Thought,” and “The Right Move” by Andrew Michael Britton [PRS] & David Stephen Goldsmith [PRS], “Midsummer” by Uwe Buschkotter [GEMA], “The Grand Opening” by Laurent Dury [SACEM], “Drifting Satellite” by Théo Boulenger [SACEM], “Man and Machine” by Larry Groupe [BMI], “A Little Optimism 1” by Joel Goodman [ASCAP], “Easy Does It” by Alchemist [SIAE], “Variations” by Stephan Sechi [ASCAP], “Bright and Playful” by Oscar Lo Brutto [PRS]; via Universal Production MusicComplete transcript available.Watch this video on the NASA Goddard YouTube channel. || 13907_Landsat_Cousteau_poster.png (1920x1080) [3.1 MB] || 13907_Landsat_Cousteau_poster_print.jpg (1024x576) [287.2 KB] || 13907_Landsat_Cousteau_poster_searchweb.png (320x180) [114.6 KB] || 13907_Landsat_Cousteau_poster_thm.png (80x40) [8.1 KB] || 13907_Landsat_Cousteau-pr.mov (1920x1080) [7.2 GB] || 13907_Landsat_Cousteau-yt.mp4 (1920x1080) [938.3 MB] || 13907_Landsat_Cousteau-tw.mp4 (1280x720) [301.1 MB] || 13907_Landsat_Cousteau-tw.webm (1280x720) [59.6 MB] || 13907_Landsat_Cousteau-captions.en_US.srt [11.3 KB] || 13907_Landsat_Cousteau-captions.en_US.vtt [10.8 KB] || ", "hits": 77 }, { "id": 4850, "url": "https://svs.gsfc.nasa.gov/4850/", "result_type": "Visualization", "release_date": "2021-04-29T00:00:00-04:00", "title": "Internal Ocean Tides", "description": "Data visualization featuring internal tides data from NASA Goddard's Space Flight Center simulation run.

This circle matches well with both the edge of the bedrock depression and also the residual slope of the ice surface as it flows over this depression (not shown), strongly supporting the inference that this depression is another large impact crater.This video is also available on our YouTube channel. || C2_Crater_4k.1524_print.jpg (1024x576) [111.8 KB] || C2_Crater_4k.1524_searchweb.png (320x180) [88.0 KB] || C2_Crater_4k.1524_thm.png (80x40) [7.2 KB] || C2_Crater_4k_1080p30_low.mp4 (1920x1080) [23.1 MB] || C2_Crater_4k_1080p30.mp4 (1920x1080) [47.8 MB] || C2_Crater_4k_1080p30.webmhd.webm (1080x606) [11.6 MB] || C2_Crater_4k_2160p30_low.mp4 (3840x2160) [48.2 MB] || C2_Crater_4k_2160p30.mp4 (3840x2160) [85.9 MB] || 3840x2160_16x9_30p (3840x2160) [0 Item(s)] || captions_silent.24907.en_US.srt [43 bytes] || captions_silent.24907.en_US.vtt [56 bytes] || C2_Crater_4K_YouTube.mp4 (3840x2160) [245.6 MB] || C2_Crater_4K_ProRes.mov (3840x2160) [3.4 GB] || C2_Crater_4k_1080p30_low.mp4.hwshow [190 bytes] || ", "hits": 34 }, { "id": 4628, "url": "https://svs.gsfc.nasa.gov/4628/", "result_type": "Visualization", "release_date": "2018-03-23T13:00:00-04:00", "title": "Sea Ice Maximum extent 2018", "description": "This visualization shows the Arctic sea ice as it expands from October 1, 2017 to its annual maximum extent that occurred on March 17th, 2018.This video is also available on our YouTube channel. || SeaIceMax_2018.1071_print.jpg (1024x576) [195.9 KB] || SeaIceMax_2018_1080p30.mp4 (1920x1080) [41.1 MB] || SeaIceMax_2018_2160p30.webm (3840x2160) [7.6 MB] || Sea_Ice_with_dates (3840x2160) [0 Item(s)] || SeaIceMax_2018_2160p30.mp4 (3840x2160) [134.9 MB] || ArcticSeaIceMax_2018_YouTube_2160p30.mp4 (3840x2160) [171.5 MB] || SeaIceMax_2018_1080p30.mp4.hwshow [216 bytes] || ", "hits": 27 }, { "id": 4600, "url": "https://svs.gsfc.nasa.gov/4600/", "result_type": "Visualization", "release_date": "2018-01-31T00:00:00-05:00", "title": "Sixty Years of Earth Observations: from Explorer-1 (1958) to CYGNSS (2017)", "description": "Earth observing spacecraft from Explorer-1 to CYGNSSThis video is also available on our YouTube channel. || explorer1_68_1920x1080.09999_print.jpg (1024x576) [149.7 KB] || explorer1_68_1920x1080.09999_searchweb.png (320x180) [76.7 KB] || explorer1_68_1920x1080.09999_thm.png (80x40) [5.8 KB] || explorer1_68_1920x1080_p60.mp4 (1920x1080) [73.6 MB] || firsts (1920x1080) [0 Item(s)] || explorer1_68_1920x1080_p30.webm (1920x1080) [35.9 MB] || explorer1_68_1920x1080_p30.mp4 (1920x1080) [124.5 MB] || explorer1_68_1920x1080.1080p30.mp4 (1920x1080) [128.5 MB] || 9600x3240_16x9_30p (9600x3240) [0 Item(s)] || 3840x2160_16x9_60p (3840x2160) [0 Item(s)] || explorer1_68_3840x2160_p30.mp4 (3840x2160) [461.5 MB] || ", "hits": 125 }, { "id": 4583, "url": "https://svs.gsfc.nasa.gov/4583/", "result_type": "Visualization", "release_date": "2017-11-20T10:00:00-05:00", "title": "NASA's Near-Earth Science Mission Fleet: March 2017", "description": "NASA Near-Earth Science Fleet (August 2017) || near_earth_sciences02.6100_print.jpg (1024x576) [69.3 KB] || near_earth_sciences02.6100_searchweb.png (320x180) [44.2 KB] || near_earth_sciences02.6100_thm.png (80x40) [4.0 KB] || near_earth_sciences02_1080p60.mp4 (1920x1080) [51.2 MB] || 1920x1080_16x9_60p (1920x1080) [0 Item(s)] || near_earth_sciences02_1080p60.webm (1920x1080) [12.6 MB] || near_earth_sciences02_360p30.mp4 (640x360) [6.6 MB] || 9600x3240_16x9_30p (9600x3240) [0 Item(s)] || ", "hits": 32 }, { "id": 4563, "url": "https://svs.gsfc.nasa.gov/4563/", "result_type": "Visualization", "release_date": "2017-11-13T13:00:00-05:00", "title": "Ocean flows at surface and 2000 meters below sea level", "description": "Visualization showing global ocean currents from Jan 01, 2010 to Dec 31, 2012 at sea level then at 2000 meters below sea level. || final01_world_current.1000_print.jpg (1024x576) [241.7 KB] || final01_world_current.1000_searchweb.png (320x180) [103.0 KB] || final01_world_current.1000_thm.png (80x40) [7.1 KB] || global (1920x1080) [0 Item(s)] || final01_world_current.webm (1920x1080) [6.4 MB] || final01_world_current.mp4 (1920x1080) [100.7 MB] || final01_world_current.m4v (640x360) [13.5 MB] || final01_world_current.mp4.hwshow [187 bytes] || ", "hits": 171 }, { "id": 4590, "url": "https://svs.gsfc.nasa.gov/4590/", "result_type": "Visualization", "release_date": "2017-10-27T00:00:00-04:00", "title": "Southern Africa Drought", "description": "When a giant swell of warm water, known as El Niño emerged in the Pacific Ocean in 2015, scientists knew to look for impacts. As El Niño changed global weather patterns Southern Africa went into severe drought. On top of already dry conditions, the region experienced its lowest rainfall in 35 years.With the Soil Moisture Active Passive (SMAP) mission, launched in 2015, NASA has dedicated soil moisture measurements for the first time – and could see this severe drought emerging. SMAP's highly sensitive microwave radiometer detects the energy emitted by soil depending on how wet or how dry it is. The old gardener's trick is to squeeze a handful of dirt in your hand and see whether it clumps or falls apart. Think of SMAP doing the same thing – with a lot more precision, all around the world, every 3 days.SMAP allowed us to see a connection between Pacific Ocean water temperatures and the moisture of the soil in Southern Africa. These measurements are now being put to operational use more than ever. SMAP's data was fed into the USDA's global crop yield forecasts – the Foreign Agriculture Service reports that help drive multi-billion dollar commodity markets around the world. In fact, the Foreign Ag Service scientist for this region said that with SMAP they now have the first reliable soil moisture data in 30 years.As crops failed and soils were left bare, we used the Terra and Aqua satellites to assess these effects on the vegetation from a local to regional scale. The Normalized Differential Vegetation Index (NDVI) reflects the health of vegetation on the land surface.As this drought spread across Southern Africa, nearly 30 million people were at risk of drastic food shortages. Four out of 10 people did not have access to clean drinking water.The analyses and data provided by NASA scientists are also critical to a USAID program called the Famine Early Warning Systems Network. As food crises arise, the global view provided by NASA scientists informs decisions about where governments and relief agencies should send help.In Southern Africa in 2015 and 2016, nearly 350 million dollars of emergency water and food aid were delivered, in part based on NASA data, to aid millions of people.As the peak of the drought hits in January 2016, the animations show the low soil moisture conditions in Zambia, Zimbabwe, and Botswana. Correspondingly the low vegetation appears in that region as well. || ", "hits": 38 }, { "id": 4586, "url": "https://svs.gsfc.nasa.gov/4586/", "result_type": "Visualization", "release_date": "2017-10-05T00:00:00-04:00", "title": "Hurricane Tracks from 2017 with Precipitation and Cloud Data", "description": "2017 Atlantic Hurricane season storm tracks with IMERG precipitation and GOES clouds (01 Aug 2017 to 31 Oct 2017) || hurricane_tracks2017_09cpc.2500_print.jpg (1024x576) [187.1 KB] || hurricane_tracks2017_09cpc.2500_searchweb.png (180x320) [111.1 KB] || hurricane_tracks2017_09cpc.2500_thm.png (80x40) [8.1 KB] || atlantic (1920x1080) [0 Item(s)] || hurricane_tracks2017_1920x1080.webm (1920x1080) [28.1 MB] || hurricane_tracks2017_1920x1080.mp4 (1920x1080) [504.9 MB] || 3840x2160_16x9_30p (3840x2160) [0 Item(s)] || hurricane_tracks2017_640x360p30.mp4 (640x360) [78.6 MB] || hurricane_tracks2017_4k.mp4 (3840x2160) [1.5 GB] || ", "hits": 62 }, { "id": 4565, "url": "https://svs.gsfc.nasa.gov/4565/", "result_type": "Visualization", "release_date": "2017-05-04T19:00:00-04:00", "title": "Seasonal Changes in Carbon Dioxide", "description": "Narrated visualization showing seasonal drawdown in carbon dioxideThis video is also available on our YouTube channel. || co2_science_comp.0740_print.jpg (1024x576) [118.8 KB] || co2_science_comp.0740_searchweb.png (180x320) [75.9 KB] || co2_science_comp.0740_thm.png (80x40) [6.1 KB] || CO2_Science_001_DDMMYY.m4v (1280x720) [66.6 MB] || CO2_Science_001_DDMMYY.webmhd.webm (1080x606) [17.7 MB] || CO2_Science_001_MM.m4v (1280x720) [66.5 MB] || comp (1920x1080) [0 Item(s)] || CO2_Science_001_DDMMYY.mp4 (1920x1080) [147.8 MB] || CO2_Science_001_MM.mp4 (1920x1080) [147.9 MB] || CO2_Science.en_US.srt [1.7 KB] || CO2_Science.en_US.vtt [1.7 KB] || CO2_Science_001_DDMMYY.mov (1920x1080) [1.1 GB] || CO2_Science_001_MM.mov (1920x1080) [1.1 GB] || ", "hits": 565 }, { "id": 4558, "url": "https://svs.gsfc.nasa.gov/4558/", "result_type": "Visualization", "release_date": "2017-04-19T00:00:00-04:00", "title": "NASA's Earth Observing Fleet: March 2017", "description": "NASA's Earth observing fleet as of March 2017 || final_earth_obs_fleet06.2100_print.jpg (1024x576) [96.1 KB] || final_earth_obs_fleet06.2100_searchweb.png (320x180) [62.3 KB] || final_earth_obs_fleet06.2100_thm.png (80x40) [4.5 KB] || final_earth_obs_fleet06_1080p60.mp4 (1920x1080) [46.9 MB] || final_earth_obs_fleet06_1080p60.webm (1920x1080) [11.2 MB] || final (1920x1080) [0 Item(s)] || final_earth_obs_fleet06_360p30.mp4 (640x360) [6.0 MB] || final06 (9600x3240) [0 Item(s)] || ", "hits": 43 }, { "id": 4564, "url": "https://svs.gsfc.nasa.gov/4564/", "result_type": "Visualization", "release_date": "2017-03-22T12:00:00-04:00", "title": "Arctic Daily Sea Ice Concentration from Arctic Minimum 2016 to Arctic Maximum 2017", "description": "This movie begins at Arctic Minimum on September 10, 2016 and shows daily sea ice concentration until the Arctic maximum on March 7, 2017.

These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven primarily by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation. In these regions, the surface water becomes dense enough to sink to the ocean depths. This pumping of surface water into the deep ocean forces the deep water to move horizontally until it can find an area on the world where it can rise back to the surface and close the current loop. This usually occurs in the equatorial ocean, mostly in the Pacific and Indian Oceans. This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations.This animation shows one of the major regions where this pumping occurs, the North Atlantic Ocean around Greenland, Iceland, and the North Sea. The surface ocean current brings new water to this region from the South Atlantic via the Gulf Stream and the water returns to the South Atlantic via the North Atlantic Deep Water current.

Aquarius will also demonstrate a measurement capability that can be applied to future operational missions.

Cold, high-salinity water masses sink and trigger the ocean's \"themalhaline circulation\" - the surface and deep currents that distribute solar energy to regulate Earth's climate. By measuring salinity, Aquarius will provide new insight into this global process. Aquarius' measurements of ocean salinity will provide a new perspective on the ocean and its links to climate, greatly expanding upon limited past measurements. Aquarius salinity data - combined with data from other sensors that measure sea level, ocean color, temperature, winds and rainfall will give us a much clearer picture of how the ocean works, how it is linked to climate, and how it may respond to climate change.Aquarius will provide information that will help improve predictions of future climate trends and short-term climate events such as El Niño and La Niña.

In these regions, surface temperatures remain below freezing for a portion of each year. Since ice and snow exist relatively close to their melting point, they frequently change from solid to liquid and back again due to fluctuations in surface temperature. Although direct measurements of the cryosphere can be difficult to obtain due to the remote locations of many of these areas, using satellite observations scientists monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.This animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The animation begins in Antarctica, showing some unique features of the Antarctic landscape found nowhere else on earth. Ice shelves, ice streams, glaciers, and the formation of massive icebergs can be seen clearly in the flyover of the Landsat Image Mosaic of Antarctica. A time series shows the movement of iceberg B15A, an iceberg 295 kilometers in length which broke off of the Ross Ice Shelf in 2000. Moving farther along the coastline, a time series of the Larsen ice shelf shows the collapse of over 3,200 square kilometers ice since January 2002. As we depart from the Antarctic, we see the seasonal change of sea ice and how it nearly doubles the apparent area of the continent during the winter.From Antarctica, the animation travels over South America showing glacier locations on this mostly tropical continent. We then move further north to observe daily changes in snow cover over the North American continent. The clouds show winter storms moving across the United States and Canada, leaving trails of snow cover behind. In a close-up view of the western US, we compare the difference in land cover between two years: 2003 when the region received a normal amount of snow and 2002 when little snow was accumulated. The difference in the surrounding vegetation due to the lack of spring melt water from the mountain snow pack is evident.As the animation moves from the western US to the Arctic region, the areas affected by permafrost are visible. As time marches forward from March to September, the daily snow and sea ice recede and reveal the vast areas of permafrost surrounding the Arctic Ocean.The animation shows a one-year cycle of Arctic sea ice followed by the mean September minimum sea ice for each year from 1979 through 2008. The superimposed graph of the area of Arctic sea ice at this minimum clearly shows the dramatic decrease in Artic sea ice over the last few years.While moving from the Arctic to Greenland, the animation shows the constant motion of the Arctic polar ice using daily measures of sea ice activity. Sea ice flows from the Arctic into Baffin Bay as the seasonal ice expands southward. As we draw close to the Greenland coast, the animation shows the recent changes in the Jakobshavn glacier. Although Jakobshavn receded only slightly from 1964 to 2001, the animation shows significant recession from 2001 through 2009. As the animation pulls out from Jakobshavn, the effect of the increased flow rate of Greenland costal glaciers is shown by the thinning ice shelf regions near the Greenland coast.This animation shows a wealth of data collected from satellite observations of the cryosphere and the impact that recent cryospheric changes are making on our planet.For more information on the data sets used in this visualization, visit NASA's EOS DAAC website.Note: This animation is an update of the animation 'A Short Tour of the Cryosphere', which is itself an abridged version of the animation 'A Tour of the Cryosphere'. The popularity of the earlier animations and their continuing relevance prompted us to update the datasets in parts of the animation and to remake it in high definition. In certain cases, our experiences in using the earlier work have led us to tweak the presentation of some of the material to make it clearer.

The Antarctica coverage snown is the Landsat Image Mosaic of Antarctica. Behind the Earth is a skymap from the Tycho and Hipparcos star catalogs. This skymap is plotted in plate carrée projection (Cylindrical-Equidistant) using celestial coordinates making them suitable for mapping onto spheres in many popular animation programs. The stars are plotted as gaussian point-spread functions (PSF) so the size and amplitude of the stars corresponds to their relative intensity. The stars are also elongated in Right Ascension (celestial longitude) based on declination (celestial latitude) so stars in the polar regions will still be round when projected on a sphere. Stars fainter than the threshold magnitude, usually selected as 5th magnitude, have their magnitude-intensity curve adjusted so they appear brighter than they really are. This makes the band of the Milky Way more visible. Stellar colors are assigned based on B and V magnitudes (B and V are stellar magnitudes measured through different filters). If Tycho B and V magnitudes are unavailable, Johnson B and V magnitudes are used instead. From these, an effective stellar temperature is derived using the algorithms described in Flower (ApJ 469, 355 1996). Corrections were noted from Siobahn Morgan (UNI). The effective temperature was then converted to CIE tristimulus X,Y,Z triples assuming a black-body emission distribution. The X,Y,Z values are then converted to red-green-blue color pixels. About 2.4 million stars are plotted, but many may be below the pixel intensity resolution.

In these regions, surface temperatures remain below freezing for a portion of each year. Since ice and snow exist relatively close to their melting point, they frequently change from solid to liquid and back again due to fluctuations in surface temperature. Although direct measurements of the cryosphere can be difficult to obtain due to the remote locations of many of these areas, using satellite observations scientists monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.This animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The animation begins in Antarctica, showing ice thickness ranging from 2.7 to 4.8 kilometers thick along with swaths of polar stratospheric clouds. In a tour of this frozen continent, the animation shows some unique features of the Antarctic landscape found nowhere else on earth. Ice shelves, ice streams, glaciers, and the formation of massive icebergs can be seen. A time series shows the movement of iceberg B15A, an iceberg 295 kilometers in length which broke off of the Ross Ice Shelf in 2000. Moving farther along the coastline, a time series of the Larsen ice shelf shows the collapse of over 3,200 square kilometers ice since January 2002. As we depart from the Antarctic, we see the seasonal change of sea ice and how it nearly doubles the size of the continent during the winter.From Antarctica, the animation travels over South America showing areas of permafrost over this mostly tropical continent. We then move further north to observe daily changes in snow cover over the North American continent. The clouds show winter storms moving across the United States and Canada, leaving trails of snow cover behind. In a close-up view of the western US, we compare the difference in land cover between two years: 2003 when the region received a normal amount of snow and 2002 when little snow was accumulated. The difference in the surrounding vegetation due to the lack of spring melt water from the mountain snow pack is evident.As the animation moves from the western US to the Arctic region, the areas effected by permafrost are visible. In December, we see how the incoming solar radiation primarily heats the Southern Hemisphere. As time marches forward from December to June, the daily snow and sea ice recede as the incoming solar radiation moves northward to warm the Northern Hemisphere.Using satellite swaths that wrap the globe, the animation shows three types of instantaneous measurements of solar radiation observed on June 20, 2003: shortwave (reflected) radiation, longwave (thermal) radiation and net flux (showing areas of heating and cooling). Correlation between reflected radiation and clouds are evident. When the animation fades to show the monthly global average net flux, we see that the polar regions serve to cool the global climate by radiating solar energy back into space throughout the year.The animation shows a one-year cycle of the monthly average Arctic sea ice concentration followed by the mean September minimum sea ice for each year from 1979 through 2004. A red outline indicates the mean sea ice extent for September over 22 years, from 1979 to 2002. The minimum Arctic sea ice animation clearly shows how over the last 5 years the quantity of polar ice has decreased by 10 - 14% from the 22 year average.While moving from the Arctic to Greenland, the animation shows the constant motion of the Arctic polar ice using daily measures of sea ice activity. Sea ice flows from the Arctic into Baffin Bay as the seasonal ice expands southward. As we draw close to the Greenland coast, the animation shows the recent changes in the Jakobshavn glacier. Although Jakobshavn receded only slightly from 1042 to 2001, the animation shows significant recession over the past three years, from 2002 through 2004.This animation shows a wealth of data collected from satellite observations of the cryosphere and the impact that recent cryospheric changes are making on our planet.For more information on the data sets used in this visualization, visit NASA's EOS DAAC website. || ", "hits": 81 }, { "id": 2953, "url": "https://svs.gsfc.nasa.gov/2953/", "result_type": "Visualization", "release_date": "2004-06-14T12:00:00-04:00", "title": "Tectonic Plates and Plate Boundaries (WMS)", "description": "The Earth's crust is constantly in motion.
