Civil servant position at The Ocean Ecology Laboratory

Open position:

The Ocean Ecology Laboratory at NASA Goddard Space Flight Center is looking to hire an Ocean Biogeochemical Modeler.  This is a full-time civil servant position at the GS-14 level, and it is open to all USA citizens. 

Background:

The Ocean Ecology Laboratory is responsible for the collection, processing, calibration, validation, archive, and distribution of ocean-related products from many operational, satellite-based remote-sensing missions providing ocean color, sea surface temperature, and sea surface salinity data to the international research community since 1996. The Ocean Ecology Laboratory also conducts research in ocean Biology and Biogeochemistry, atmospheric composition, and laboratory protocols using a combination of laboratory and field experiments, remote sensing measurements, and modeling.  The Ocean Ecology Laboratory is located at NASA Goddard Space Flight Center, Greenbelt, MD.  More information about our lab can be found at:

https://science.gsfc.nasa.gov/earth/oceanecology/

https://oceancolor.gsfc.nasa.gov/

Duties:

The selected candidate will lead efforts in the assimilation of ocean color remote sensing data into global and regional biogeochemical models. This effort has two goals: 1) Develop a better understanding of regional and global biogeochemical processes, 2) evaluate how satellite ocean color products can be improved or modified to increase usefulness for global and regional modeling.

Specific duties include:

  • Lead the development and application of global and regional biogeochemical modeling for Earth System Science research.
  • Lead the assimilation of satellite remote sensing data into biogeochemical models.
  • Publication of research papers in peer-reviewed journals

·      Support the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Mission’s Project Scientist in the evaluation of ocean and atmosphere retrieval algorithms developed within the competed PACE Science and Applications Team (SAT).

·      Lead and participate in research proposals in the fields of ocean and atmospheric remote sensing, ocean biology and biogeochemistry, atmospheric composition and modeling.  The successful candidate is expected to maintain a portfolio of funded research. 

·      Lead and participate in the publication of research manuscripts.  The successful candidate is expected to publish 1-2 papers per year. 

·      Contribute to the development of future airborne and spaceborne instrumentation and missions, in-situ instrumentation, and field campaigns pursued within The Ocean Ecology Laboratory, including requirements analyses and proposal development.

·      Other duties as required by the civil service

Education:

Ph.D or equivalent experience in Engineering or Physical Sciences.

Experience:

Demonstrable experience in:

  1. Global and regional biogeochemical modeling
  2. Assimilation of satellite remote sensing data into biogeochemical models
  3. Sensitivity analyses
  4. Publication of research papers in peer-reviewed journals
  5. Preparation of successful research proposals

Applications for this position will have to be submitted via USA Jobs https://www.usajobs.gov/GetJob/ViewDetails/607108500 . The position will be open for applications from July 22 through July 26.  Those who might be interested in applying are encouraged to become familiar with USA Jobs.

NASA: Ocean Green, Blooming Ocean

EO Kids

These tiny organisms do big things for our #LivingPlanet. Learn more about our Ocean Green with #EOkids. https://earthobservatory.nasa.gov/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.

Abstract:

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.

Keywords:

  • cyclone Nargis;
  • remote sensing;
  • MODIS and CALIPSO

The Coastal Ocean from a Hyperspectral Perspective

Folks,
Just wanted to let everyone know that there is a new feature on the Ocean Color Web homepage ( http://oceancolor.gsfc.nasa.gov/ ) 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:
