This animation depicts the part of Earth's ocean circulation model that involves heat transfer.In the polar latitudes the ocean loses heat to the atmosphere. Near the equator ocean water warms, and because it is less dense, it remains close to the surface. Cast away from the planet's equator by the winds and Earth's rotation, warm equatorial waters travel on or near the surface of the globe outward toward high latitudes. But as water loses heat to the increasingly cold atmosphere far away from the equator it sinks and pushes other water out of the way. Endlessly, this pump known as Meridional Overturning Circulation, circulates water and heat around the globe. Considering that the ocean stores exponentially more heat than the atmosphere and the fact that they're always in direct contact with each other, there's a strong relationship between oceanic heat and atmospheric circulation. || ", "hits": 69 }, { "id": 3881, "url": "https://svs.gsfc.nasa.gov/3881/", "result_type": "Visualization", "release_date": "2011-12-09T15:00:00-05:00", "title": "Thermohaline Circulation on a Flat Map", "description": "The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. 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. The continual influx of warm water into the North Atlantic polar ocean keeps the regions around Iceland and southern Greenland generally free of sea ice year round.The animation also shows another feature of the global ocean circulation: the Antarctic Circumpolar Current. The region around latitude 60 south is the only part of the Earth where the ocean can flow all the way around the world with no obstruction by land. As a result, both the surface and deep waters flow from west to east around Antarctica. This circumpolar motion links the world's oceans and allows the deep water circulation from the Atlantic to rise in the Indian and Pacific Oceans, thereby closing the surface circulation with the northward flow in the Atlantic.The flows in this visualization are based on current theories of the thermohaline circulation rather than actual data or computational model runs. The thermohaline circulation is a very slow moving current that can be difficult to distinguish from general ocean circulation. Therefore, it is difficult to measure and simulate.This visualization was produced for the Science On a Sphere production \"Loop\". It is intended to be over-layed on a world map background. Below are 3 sets of 4 sequences. The first set of 4 sequences are all composited over a world map background with a limited number of frames that make them loopable (with a very slight jump at the point where the looping happens). This is primarily provided for real-time displays such as hyperwall systems. The 4 sequences are: all depth layers combined, shallow depths, middle depths, and deep depths.The second set is the same as the first set except that the layers are not composited over the background and instead include and alpha channel. The third layer is actually the frames that were used in the film \"Loop\" and consist of a large number of continuous, seamless frames. Each sequence is as before, all layers, shallow, middle, and deep layers all with alpha channels.The depth layers nominally correspond to the following ranges below sea level: shallow (0m - 600m), middle (1875m - 2500m), and deep (3000m - 4000m). These depths do vary with bathymetry. So, in areas where the sea floor is not very deep, these depths are scaled so that the flows do not interesct the sea floor or each other. || ", "hits": 154 }, { "id": 10841, "url": "https://svs.gsfc.nasa.gov/10841/", "result_type": "Produced Video", "release_date": "2011-11-10T00:00:00-05:00", "title": "Perpetual Ocean", "description": "Driven by wind and other forces, currents on the ocean surface cover our planet.

Since each spacecraft is at a slightly different distance from the Sun, the intensity received by each pixel was normalized to correspond to the intensity one astronomical unit from the Sun using the inverse-square law.

The magnetic field partially shields the Earth from harmful charged particles emanating from the sun. The field is stretched back away from Sun by solar particle and radiation pressures.The geomagnetic field is generated (and regenerated) as the conducting fluid of the Earth's mantle and core, driven by convection of heat from deeper in the interior, induces an electromotive force (EMF) with the existing magnetic field. This process is very similar to the way an electric generator generates a voltage. That voltage then drives an induced current in the conducting fluid, which also produces a magnetic field. This feedback mechanism helps maintain the field, continuously converting the thermal energy in the Earth into magnetic field energy.The magnetic field line data used in this visualization is from a simplified static model. More complex models deform the magnetic field over time as the Earth rotates and experiences solar pressures. Many of the field lines (particulary near the back, away from the Sun) should eventually connect (north and south poles), but the 3d model used in this visualization does not extend far enough to see this.The day/night terminator is aligned with the Sun and is therefore aligned with the magnetic field too.

Several different remote sensing data products have been used to study surface and near-surface melt characteristics of the Greenland ice sheet for the 2007 melt season when record melt extent and runoff occurred. Here, MODIS daily land surface temperature and a special diurnal melt product, derived from QuikSCAT scatterometer data, measure the evolution of melt on the ice sheet. Although these daily products are sensitive to different geophysical features, they show excellent correspondence when surface melt is present. This animation displays these two geophysical data products of the Greenland ice sheet side-by-side, showing MODIS data on the left side and QuikSCAT data on the right. The 2007 melt season is shown twice. In the first sequence, MODIS surface temperature is compared with several categories of QuikSCAT melt between March 15th and October 13th, 2010. During this sequence, active melt detected by QuikSCAT is shown in light blue, reduced melt is medium blue, and completed melt is dark blue. For the MODIS, surface temperature is shown with the color scale — red indicates a surface temperature greater than -1 degree Celsius. As MODIS shows warmer surface temperature as the melt season progresses, QuikSCAT consistently identifies the corresponding melt.In the second sequence, the MODIS and QuikSCAT melted regions of the ice sheet were accumulated during the melt season. QuikSCAT captures melt earlier, and then melt is detected by MODIS shortly afterward at a higher spatial resolution. The final result (frame) shows the seasonal melt extent which was consistently delineated by both sensors.

The movie presents advanced satellite data and other visual effects on a dramatic spherical screen, affording viewers a chance to experience planets and planetary science in a way that's more natural to their actual appearance. The Earth guest stars in a variety of guises, from depictions of the biosphere to planetary views of city lights at night to dramatic examinations about the science of hurricane formation. Other moons and planets make exciting cameos too, with special presentations of Mars and Earth's moon.Media and visualization experts at NASA began working with the NOAA technology in the fall of 2005. Until that time, Science On a Sphere had already established an impressive reputation for depiction of planetary data in a dramatic way. But FOOTPRINTS marks the first time that a thorough set of techniques and artistic rules have been applied in the service of a full featured production presented on a spherical screen. But more than just a showcase for discrete data sets, the 16 minute film provides a conceptual framework about the human drive to explore. By contextualizing data with compelling language, inventive pictures, and dramatic sound, FOOTPRINTS seeks to engage and enthuse audiences who may not understand the practicalities and majesty of NASA's and NOAA's observations, and may not otherwise have any contact with what these two science agencies actually do. As a presentation tool, Science On a Sphere is relatively new. NOAA invented and developed its core hardware and software within the past few years. According to Dr. Alexander MacDonald, the NOAA scientist located at the Earth System Research Laboratory in Boulder, Colorado, who originally conceived of it, Science On a Sphere is intended to present global science as it should be presented and to stimulate students to learn more about the Earth's environment and the solar system.In the past few years Science On a Sphere systems have begun to be installed in museums and science centers around the world. Scientists and administrators at NASA Goddard saw potential to use the Sphere as both a teaching and an outreach tool and with NOAA's support decided to bring one to the campus. It's currently installed at the Goddard Visitor Center.For several years there has been a slowly growing list of planetary data sets that can play on Spheres located in museums and institutions around the country. NASA and NOAA intend to dramatically augment that collection with new images and data. But FOOTPRINTS changes the playing field. With the release of this film, the Goddard team dramatically catapults forward the capabilities of the system, taking it far beyond its initial limits of merely depicting planetary data sets. Beyond encompassing state of the art data visualizations, the production team developed new ways for working with computer generated illustrations and animation, high definition video, graphics, text, and more. In a little more than three and a half months, the core group developed a palette of new technical processes and aesthetic guidelines for presenting media on the Sphere.The movie asks audiences to consider the idea that what they know is only a function of what questions they're willing to ask. It's an intellectual and creative backdrop to the overall production, and also a philosophical backdrop to the excitement about the vital work that NASA and NOAA do in service of the public interest. || ", "hits": 105 }, { "id": 10573, "url": "https://svs.gsfc.nasa.gov/10573/", "result_type": "Produced Video", "release_date": "2010-06-10T00:00:00-04:00", "title": "RETURN TO THE MOON", "description": "NASA's home for spherical films on Magic Planet. Download the Magic Planet-ready movie file here.The silvery disc of inspiration for countless philosophers and lovers also happens to be one of the great destinations in the annals of exploration. Earth's moon shines like a beacon, beckoning scientists and the simply curious. But it's been a long time since anyone has visited, and even the most basic signals from unmanned probes have been few and far between. Unfold your maps. With the advent of the NASA's Lunar Reconnaissance Orbiter (LRO), humanity makes a return to the moon like a herald announcing a new age. To commemorate the mission and champion the value of future planned lunar expeditions, the Space Agency created a new short film called RETURN TO THE MOON. Designed expressly for the Science On a Sphere platform, a striking spherical projection system now playing in theaters around the world, RETURN TO THE MOON shows off our silver sibling like a jewel of the night. Starting with a brief historical look back at the legacy of human achievement in lunar exploration, the movie presses audiences to take stock in their own relationship to the moon. Then it takes them on a journey. Travelling along with the LRO spacecraft, viewers will discover some of the essential scientific subjects that scientists plan to study. They'll follow LRO as it makes orbits around the moon, gathering data about the surface and what may lie beneath. And then, in a dramatic demonstration of a daring part of the mission, moviegoers will witness the inventive and powerful moment when NASA engineers intentionally crash a research probe into the surface of the moon to dig beneath the top layer. The space agency calls that impact probe LCROSS, and as both a research tool and a cinematic experience, it promises to deliver something exciting. RETURN TO THE MOON was produced by the media team at the Goddard Space Flight Center. One of NASA's premiere media teams, this group not only delivers state of the art data visualizations of ongoing research, but also helped write the book on spherical filmmaking. At its time of release, RETURN TO THE MOON was the third fully produced spherical movie from Goddard, and an exciting departure in terms of how these kind of products fuse dramatic presentational style with robust science. || ", "hits": 49 }, { "id": 10552, "url": "https://svs.gsfc.nasa.gov/10552/", "result_type": "Produced Video", "release_date": "2010-05-25T00:00:00-04:00", "title": "TIROS-1: The Forecast Revolution Begins (50th Anniversary)", "description": "April 1, 1960: the world's first experimental weather satellite, TIROS-1, was launched.

Download the Magic Planet-ready movie file here.Three hundred and eighty million miles from Earth, the solar system's largest planet spins like a sizzling top in the night, massive and powerful beyond all comparison short of the sun itself. It's therefore only fitting—and certainly about time—that the fifth planet receive its proper cinematic due, set naturally on the most appropriate cinematic platform. With the movie LARGEST, Jupiter comes to Science On a Sphere.LARGEST examines the gas giant like a work of art, like a destination of celestial wonder. Starting with the basics, the movie examines the gross anatomy of the immense planet. From swirling winds to astounding rotational velocity to unimaginable size, Jupiter demands nothing less than a list of superlatives. But where general description sets the stage, LARGEST parts the curtains on humanity's experience with the fifth planet. The movie takes us on a journey to this immense sphere via dramatic fly-bys with some of the most astounding robotic probes ever designed. Then, with NASA instruments trained on the striped behemoth, the drama really begins.NASA released LARGEST on September 15, 2009.

FROZEN features the global cryosphere, those places on Earth where the temperature doesn't generally rise above water's freezing point. As one of the most directly observable climate gauges, the changing cryosphere serves as a proxy for larger themes.But just as thrilling as this unusual—and unusually realistic—look at the planet's structure and behavior is the sheer fun and fascination of looking at a spherically shaped movie.
