NASA: Ocean Green, Blooming Ocean

EO Kids

These tiny organisms do big things for our #LivingPlanet. Learn more about our Ocean Green with #EOkids

EO Kids, a publication from the Earth Observatory, highlights science stories for a younger audience. In our new edition, we explore the swirling seas of phytoplankton blooms and invite kids to create their own NASA science visualization by making a flipbook. Read about how these tiny organisms are making a big impact on our living Earth. Flip through the pages and see the ocean change color as phytoplankton blooms and the land changes between brown and green as the seasons change. Watch as the Earth comes alive with the flip of a page.

Three-dimensional observations from MODIS and CALIPSO for ocean responses to cyclone Nargis in the Gulf of Martaban

Shi, W., and M. Wang (2008), Three-dimensional observations from MODIS and CALIPSO for ocean responses to cyclone Nargis in the Gulf of Martaban, Geophys. Res. Lett., 35, L21603, doi:10.1029/2008GL035279.


Satellites measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua and the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) are used to study physical, optical, and biological changes in the Gulf of Martaban following the passage of cyclone Nargis during early May of 2008. The shortwave infrared (SWIR) atmospheric correction algorithm has been used to derive ocean optical and biological properties from MODIS. Following the passage of cyclone Nargis, a significant increase of surface sediment concentration is observed with considerably enhanced normalized water-leaving radiance at the red and near-infrared (NIR) wavelengths in the Gulf of Martaban and along the mouths of the Ayeyarwady River. It is estimated that, before and after cyclone Nargis, the average total suspended matter (TSM) in the Gulf of Martaban increased from 24 mg/l to 31 mg/l, while the TSM value nearly tripled from 12 mg/l to 34 mg/l along the mouths of the Ayeyarwady River. The CALIPSO measurements also show that, before cyclone Nargis, the sediment concentration in the region increases with depth in the water column, while after cyclone Nargis the sediment vertical profile becomes relatively uniform in the upper 50 m depth due to wind-driven vertical mixing and entrainment.

The Coastal Ocean from a Hyperspectral Perspective

Just wanted to let everyone know that there is a new feature on the Ocean Color Web homepage ( ) that Norman Kuring has just put together using some of the HICO data that in collaboration with our colleagues at the Naval Research Laboratory and Oregon State University, we are now making available to the broader ocean color community.  It is a wonderfully clear and creative depiction of the kind of information that is contained within the hyperspectral data from HICO.  You can access the feature directly at:
