In-situ optical data of Southeast Asia Region for NASA SeaBASS

Invitation from NASA GSFC to voluntarily submit in-situ optical data of Southeast Asia Region

“Congratulations on the concise, informative portal for ocean color in Southeast Asia. I work in coastal and global ocean color algorithm development at NASA GSFC, and have found certain regions of the world – including Southeast Asia – somewhat underrepresented in terms of accessible in situ optical data. These data are critical to ocean color characterization and algorithm calibration and validation. For this reason, I hope you will consider encouraging principal investigators visiting your site to voluntarily (if not NASA funded) submit field data to ongoing collections such as NASA’s SeaWiFS Bio-optical Archive and Storage System (SeaBASS; Thanks, and good luck with the future of the portal.”

Learn Earth Observation! Lesson development competition for Bilko

The European Space Agency (ESA) funded LearnEO! project ( has launched a lesson writing competition. With prizes of €5000, €3000 and €2000 we’re looking for the best remote sensing lessons from individuals or teams.

Lessons will provide examples of how satellite data from ESA missions can contribute to better understanding of the world we live in and the challenges we face.

Register to participate in the competition at This will give you access to resources and support for participating lesson authors and allows us to send you updates.


Anyone who uses satellite data can participate as an individual or as part of a team. Teams must nominate a first author to act on their behalf.  First authors must be over 18 on 1 January 2014.


Any application of Earth Observation is a potential lesson topic. For example

* in archaeological research or to support the management/monitoring of cultural heritage sites;

* as a management tool for reducing risks or impacts from natural or man-made hazards;

* to support the monitoring and management of terrestrial, coastal or marine ecosystems and sustainable use of living resources;

* in monitoring or research to support climate change adaptation or the management of mitigation schemes.

Geophysical, environmental or social science themes are all welcome – as long as the lesson shows how Earth Observation can contribute.


Find a good case study and think about how to present it.  Who is your target audience? What are the key points you want to make.  What processing steps are involved?

Lessons must follow the LearnEO! format, described in our author guidelines (


The lessons must include data from ESA missions on their own or in combination with data from other sources (including other satellites, model output or in situ data). Satellite data may be in the original format or pre-processed. Hands-on activities must use the Bilko software.

Detailed rules for the competition may be found in Terms and Conditions of the Competition (

All MERIS full resolution (300meter) data now available on NASA

New Announcement from NASA Ocean Color Group

“We are happy to announce that as part of the nasa-esa data sharing collaboration, we have now completed the ingest and preliminary processing of the complete mission long meris full-resolution (frs, 300 meter) data set which covers the period of envisat operations from april 2002 – april 2012.  this data set along with the corresponding level-2 products that have been produced using the standard nasa processing methodologies along with the already available reduced resolution (rr) data set is available via the multi-mission browse/order/distribution web browser at:
it should be noted that the level-1b full-resolution data that esa provided was produced using an earlier version of the calibration than was used for the full resolution data set.  we are working on a method of updating the calibration as part of our anticipated reprocessing of all the data sets that we support early next year.

attached is a coverage map showing the annual distribution of the meris full resolution data that are now available.

with our very best regards,
the ocean color group”

NASA Resumption of Ocean Color Services

Message from NASA Ocean Color Remote Sensing Services

“we are happy to announce that we have resumed full web/data/distribution/access services on the ocean color web and all data orders/subscriptions that had been suspended due to the government shutdown are now in the processing queue and should start to be available for download via the usual methods shortly.
it’s nice to be back.
best regards,
gene and the entire ocean color group”

Ocean color variability in the Indonesian Seas during the SeaWiFS era

Susanto, R. D., T. S. Moore II, and J. Marra (2006), Ocean color variability in the Indonesian Seas during the SeaWiFS era, Geochem. Geophys. Geosyst., 7, Q05021, doi:10.1029/2005GC001009.


More than 6 years of satellite-derived ocean color (SeaWiFS) and 7 years of sea surface temperature (AVHRR) and sea surface wind (ERS1/2, NSCAT, and QuikSCAT) are investigated for the Indonesian Seas. Harmonic analysis and monthly means in ocean color indicate that during the southeast Asia-Australia monsoon southeasterly wind from Australia generates upwelling and brings cooler and nutrient-rich water near the surface, enhancing productivity and increasing ocean color in the Banda Sea and the southern coasts of Jawa (Java)-Sumatra. Conditions are reversed during the northwest monsoon. The northwest wind induces downwelling and produces a weaker biological response in terms of ocean color. Anomalous winds associated with the 1997–1998 El Niño/La Niña events coinciding with the Indian Ocean Dipole (IOD) produced significant departures from the 6-year monthly mean in both magnitude and timing of the seasonal response to the southeast monsoon. Ocean color intensified in the upwelling region along the southern coast of Jawa-Sumatra, and the area of increased amplitude extended westward and prolonged the southeast monsoon period. In addition, localized minimum values of ocean color are observed along the exit pathways of the Indonesian Throughflow.

Investigation of different coastal processes in Indonesian waters using SeaWiFS data

Nani Hendiartia, Herbert Siegelb, Thomas Ohdeb

Deep Sea Research Part II: Topical Studies in Oceanography, Volume 51, Issues 1–3, January–February 2004, Pages 85–97


SeaWiFS data were applied to investigate coastal processes in Indonesian waters around the most populated island of Java. Coastal processes due to wind forcing were studied the first time using SeaWiFS-derived chlorophyll and TSM concentrations in combination with AVHRR-derived SST in the period from September 1997 to December 2001. Upwelling events were studied along the southern coast of Java during the southeast monsoon (June to September). Satellite-derived chlorophyll concentrations higher than View the MathML source and sea-surface temperatures lower than 28°C are indications of upwelling. Upwelling events influence the distribution and growth of phytoplankton and provide by that good feeding condition for zooplankton, larvae, juvenile and adult of pelagic fish.

Coastal discharge into the western Java Sea contains organic and inorganic materials originating from different sources. Diffuse impacts, particularly from fish farms and aquaculture, as well as coastal erosion influence large coastal areas during the rainy season (December to March), and to a lesser extent during the dry season. Strong Citarum river discharge was observed during the transition phase from the rainy to the dry season (March and April), when the maximum amount of transported material reaches the sea. The river plume is evident from chlorophyll concentrations higher than View the MathML source, and suspended particulate matter concentrations of more than View the MathML source. The Sunda Strait is seasonally influenced by water transport from the Java Sea and from the Indian Ocean. The satellite data show that water transport from the Java Sea occurs during the pre-dominantly easterly winds period (June to September). This is characterized by warm water (SST higher than 29.5°C) and chlorophyll concentrations higher than View the MathML source. This water transport influences the fish abundance in the Sunda Strait. High fish catches coincide with the presence of Java Sea water, while the surface currents lead to the migration of pelagic fish. Conversely, during the dominant westerly winds period, oceanic waters from the Indian Ocean with low chlorophyll concentrations influence the Sunda Strait water.
