Remote Sensing(RS)

What is Remote Sensing?

Remote sensing makes it possible to collect data on subject without any physical contact.
During the past thirty years, rapid technological growth has advanced the ability of satellites to observe and monitor the global ocean. Today, it is possible to obtain and analyze large satellite data sets such of various oceanic phenomena.
Development of new marine environmental monitoring tool by remote sensing is one of the prioritized activities of CEARAC.

Overview of Working Group 4 (WG4)

In order for CEARAC to implement activities of development of new marine environmental monitoring tools by remote sensing, NOWPAP Working Group 4 (WG4) was formed with experts on remote sensing of marine environment from each NOWPAP member state. With the consensus of the NOWPAP member states, activities on remote sensing applications with a focus on eutrophication and oil spills have been implemented since 2003.

Activities of WG4

1.Achievements in the past (-2007)

I. National Reports / Integrated Report on RS (2004-2005)

WG4 summarized the status of the ocean remote sensing (RS) for the NOWPAP member states and published the National Reports and the Integrated Report on Ocean Remote Sensing for the NOWPAP region.

II. Remote Sensing Information Network (2003-2005)

WG4 established information network concerning ocean remote sensing. The following websites are now in operation and providing useful information.

III. Eutrophication Monitoring Guidelines by Remote Sensing (2006-2007)

WG4 published Eutrophication Monitoring Guidelines by Remote Sensing based on case study conducted in Toyama Bay. The guidelines were made aiming at coastal managers in local government and professional researchers, for translating satellite remote sensing into information and tools that are useful for monitoring of eutrophication, which represents one of the most severe and widespread environmental problem in the NOWPAP region.

IV. Training on RS data analysis (2007)

The training course on RS data analysis was organized.
Venue: Nagasaki University,  Nagasaki, Japan.
Date: Sep 3-7, 2007
Participants: 23 trainees
(students and young researchers from the NOWPAP
member states and IOC/WESTPAC member states)

2. Activities for 2008-2009

I. Development of educational materials for utilization of RS data for coastal environment conservation

WG4 developed educational materials for utilization of RS data for coastal environment conservation for students, young researchers and coastal managers in the NOWPAP region.

II. Organization of the second NOWPAP training course on RS data analysis

The 2nd NOWPAP Training Course on RS Data Analysis was organized for students, young researchers and coastal managers to obtain useful skills and knowledge to utilize RS data in monitoring and assessment of the marine environment.

Venue: Cheju National University, Jeju, Korea.
Date: Nov 1-5, 2008
Participants: 23 trainees

III. Development of procedures for assessment of eutrophication status

As a joint activity of WG3 and WG4, "Procedures for assessment of eutrophication status including evaluation of land based sources of nutrients for the NOWPAP region (Common Procedures)" were be developed by utilizing RS techniques.
Application of the Common Procedures are planned in the selected sea areas of the NOWPAP member states to evaluate suitability of suggested methodology for the assessment of eutrophication status.
