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.

The extra energy is mostly released as heat as the plants respirate oxygen and water vapor. But a fraction of that energy is re-emitted as fluorescent light, particularly in red wavelengths. MODIS is the first instrument to observe this signal on a global scale.Red-light fluorescence says something about the physiology of plants and the efficiency of photosynthesis, as different parts of the plant's energy-harnessing machinery are activated based on the amount of light and nutrients available. The amount of fluorescence increases when plants are under stress from a lack of iron, a critical nutrient in the sea. When water is iron-poor, plants slow their growing processes and struggle to dissipate excess solar energy that cannot be used in photosynthesis. The fluorescence data from MODIS gives scientists a tool to see where waters are iron-enriched or iron-limited, and where plankton might flourish or not. Iron is typically picked up by winds blowing dust from deserts and other arid areas, and by river plumes and island currents. || ", "hits": 26 }, { "id": 3454, "url": "https://svs.gsfc.nasa.gov/3454/", "result_type": "Visualization", "release_date": "2007-11-05T00:00:00-05:00", "title": "SeaWiFS Biosphere Data over the North Pacific", "description": "The SeaWiFS instrument aboard the Seastar satellite has been collecting ocean data since 1997.

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).
