Areas where plants thrive are light blue and yellow, while less productive regions are dark blue. The satellite records the amount of light that chlorophyll is soaking up as the plant converts light, water, and carbon dioxide into glucose and oxygen through photosynthesis. In general, high chlorophyll corresponds with a high number of healthy plants. The global relationship between temperature and productivity was one that scientists first observed in SeaWiFS data. The places with the lowest chlorophyll concentrations are in the tropics, while the cold waters in the Arctic and Antarctic have high chlorophyll concentrations. What the image does not show is that the growth at the poles is seasonal. The plants only flourish during the spring and summer when there is sufficient light to fuel photosynthesis. || ", "hits": 158 }, { "id": 3877, "url": "https://svs.gsfc.nasa.gov/3877/", "result_type": "Visualization", "release_date": "2013-10-01T00:00:00-04:00", "title": "Dynamic Earth Dome Show - Biosphere", "description": "This visualization was a prototype affiliated with the 'Dynamic Earth', an Earth science planetarium show. The visualization shows the global biosphere and NDVI from the SeaWiFS instrument with MODIS ice and snow overlayed.The images were rendered using a fish eye technique so that they would project properly onto a planetarium dome.Earth scientists are able to measure many of the Earth's 'vital signs', and just like a doctor measures our vital signs to see how healthy we are. Scientists will use these measurements of the Earth to better understand how the Earth functions, how the different systems on Earth interact and how those interactions have set the stage upon which life flourishes. The visualization shows a timeseries of images of SeaWiFS Global Biosphere - the ocean's long-term average phytoplankton chlorophyll concentration acquired between September 1997 and September 2007 combined with the SeaWiFS-derived Normalized Difference Vegetation Index over land. On land, the dark greens show where there is abundant vegetation and tans show relatively sparse plant cover. In the oceans, red, yellow, and green pixels show dense phytoplankton blooms, those regions of the ocean that are the most productive over time, while blues and purples show where there is very little of the microscopic marine plants called phytoplankton. Remote sensing, especially using satellite-mounted colour scanners (SeaWiFS and similar platforms), is advocated for broad-based monitoring of chlorophyll once appropriate algorithms have been developed and proved. The concentration of the photosynthetic pigment chlorophyll a (referred to as chlorophyll) in marine waters is a proven indicator of the biomass of phytoplankton, the organisms that constitute the base of the marine food web. Fluorometry provides an estimate of chlorophyll levels in sea water and thus an estimate of primary productivity in the upper part of the water column.For more information on monitoring the Earth from Space with SeaWIFS see http://oceancolor.gsfc.nasa.gov/SeaWiFS/TEACHERS/. || ", "hits": 51 }, { "id": 10971, "url": "https://svs.gsfc.nasa.gov/10971/", "result_type": "Produced Video", "release_date": "2012-05-08T00:00:00-04:00", "title": "Super Blooms", "description": "Turbulent storms churn the ocean in winter, adding nutrients to sunlit waters near the surface. This sparks a feeding frenzy each spring that gives rise to massive blooms of phytoplankton. Tiny molecules found inside these microscopic plants harvest vital energy from sunlight through photosynthesis. The natural pigments, called chlorophyll, allow phytoplankton to thrive in Earth's oceans and enable scientists to monitor blooms from space. Satellites reveal the location and abundance of phytoplankton by detecting the amount of chlorophyll present in coastal and open waters—the higher the concentration, the larger the bloom. Observations show blooms typically last until late spring or early summer, when nutrient stocks are in decline and predatory zooplankton start to graze.

Phytoplankton are very small, single-celled plants, generally smaller than the size of a pinhead that contain a green pigment called chlorophyll. All plants (on land and in the ocean) use chlorophyll to capture energy from the sun and through the process known as photosynthesis convert water and carbon dioxide into new plant material and oxygen. Although microscopic, phytoplankton can bloom in such large numbers that they can change the color of the ocean to such a degree that we can measure that change from space. The basic principle behind the remote sensing of ocean color from space is this: the more phytoplankton in the water, the greener it is...the less phytoplankton, the bluer it is.

A check up of the Earth's planetary health reveals that the lowest rung in the ocean food chain is shrinking. For the past 20 years (early 1980s to present), phytoplankton concentrations declined as much as 30 percent in northern oceans. Scientists from NASA, the National Oceanic and Atmospheric Administration (NOAA), and Oregon State University say warmer ocean temperatures and low winds may be depriving the tiny ocean plants of necessary nutrients. However, they still do not know if the loss of phytoplankton is a long-term trend or a climate oscillation. Scientists can monitor ocean and planetary health through phytoplankton. Since the whole ocean food chain depends on the health and productivity of phytoplankton, a significant change could indicate a shift in our climate. Phytoplankton consists of many diverse species of microscopic free-floating ocean plants that form the base of the ocean's food chain. These plants thrive on sunlight and nutrients. Limit either one and phytoplankton will not grow. This animation shows the Multivariate ENSO Index (MEI) in red and the net primary production NPP anomaly in units of Tgrams carbon per month in green. The MEI is a multivariate index that incorporates sea level pressure, surface zonal and meridional wind components, sea surface temperature, surface air temperature, and cloudiness (Wolter and Timlin, 1998). The MEI index is calculated for the tropical Pacific (i.e., between 10 degrees North and 10 degrees South, from Asia to the Americas) with units of kg m-3. The Net Primary Production (NPP) data was generated from the Vertically Generalized Production Model (VGPM).

Towering redwood trees, majestic plains of grasses on Asian steppes: Earth's living glow fills the eye with diversity, resilience, and endless Darwinian invention.But arguably one of the most essential populations on Earth would have no chance if pitted against others in a contest based on looks alone. More than any other kind of life, the Earth lives and breathes because of the profound success of lowly phytoplankton.Phytoplankton is a broad, catch-all name for a wide category of simple organisms living primarily in the world's oceans. Floating in vast fields of billions of tiny individual plants, these essential life forms make up a colossal proportion of the Earth's total biomass. It's also vital to the overall web of life on Earth. Phytoplankton serves not only as the base of the aquatic food chain, but also as the principal source of atmospheric oxygen worldwide.As global climate continues to change, a complex set of forces begins to push and pull on the ability of phytoplankton populations to thrive. Changing global ocean temperatures have enormous influences, as does changing ocean chemistry. But while this may present itself as a subject of purely academic interest, phytoplankton populations may present one of the most vital bellwethers for practical changes beginning to take hold of a planet in transition.NASA's SeaWiFS spacecraft is one of the most powerful tools in keeping up with these trends. A small, low cost vehicle and instrument package, SeaWiFS monitors the colors of the world everyday.

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": 86 }, { "id": 3180, "url": "https://svs.gsfc.nasa.gov/3180/", "result_type": "Visualization", "release_date": "2005-07-31T00:00:00-04:00", "title": "MODIS Daily Global Snow Cover and Sea Ice Surface Temperature as seen in the SIGGRAPH 2005 Electronic Theater", "description": "This animation showing snow cover and sea ice surface temperature in the Northern Hemisphere portrays data collected from daily MODIS satellite images acquired during the winter of 2002-2003.

Daily changes in sea ice are shown as ice surface temperature, which is related to the air temperature and the concentration of the sea ice. Sea ice surface temperatures range from about -40 to -2 degrees Celsius. Here, ice surface temperatures are depicted by colors, described by a color bar shown below.

This warm water trapped the ocean nutrients that normally come to the surface in the upwelling cold water, leading to a drastic decrease in phytonplankton and other ocean life in the region. The unique Galapagos ecosystem was severely affected and many species, including sea lions, seabirds, and barracudas, suffered a very high mortality level. During the second week of May, 1998, the ocean temperatures plummeted 10 degrees in one day, and the ocean productivity exploded with large phytoplankton blooms. After this time, many species recovered very rapidly and the land species started to reproduce immediately. The SeaWiFS instrument, which monitors global phytoplankton in the oceans by measuring the color of reflected light, caught this dramatic recovery. This visualization shws images from SeaWiFS starting on May 10, 1998 and ending on May 31, 1998, where ocean colors of blue or purple represents little or no ocean life and colors or yellow and red indicate significant ocean productivity.

Major changes were observed regionally: chlorophyll concentrations decreased in the northern high latitudes while chlorophyll in the low latitudes increased.
