Satellite Chlorophyll-a Assessment of Eutrophication in NOWPAP Region

Evaluate eutrophication levels using satellite-derived chlorophyll-a concentration data from 1998 to 2017 in the Northwest Pacific region. The study highlights the transition from oligotrophic to eutrophic conditions and offers a rapid assessment approach. Collaboration with GCOM-Mission enhances applicability in coastal zones.

  1. Assessment of eutrophication using satellite derived chlorophyll-a concentration in the NOWPAP region Genki Terauchi Email: Terauchi@npec.or.jp Northwest Pacific Action Plan Special Monitoring & Coastal Environmental Assessment Regional Activity Centre(NOWPAPCEARAC)

  2. Assessment of eutrophication by the NOWPAP Common Procedure More eutrophic Threshold = 5 ug/L Oligotrophic (Less eutrophic) Becoming oligotrophic (less eutrophic) Becoming eutrophic NOWPAP CEARAC 2009, 2014)

  3. Assessment of eutrophication in the Northwest Pacific Region using satellite Chl-a from 1998 to 2015 0.1 1 10 64 mg m-3 -0.3 0 0.3 (mg m-3/year) Terauchi et al (2018)

  4. Rapid assessment of eutrophication using satellite Chl-a from 1998 to 2017 G. Terauchi and E. R. Maúre(2018)

  5. Use of SGLI of the GCOM-Mission will enhance the applicability of satellite Chl-a in eutrophication assessment in coastal zone Chlorophyll-a concentration on May 23, 2018 observed by SGLI on board GCOM-C mission. Image provided by Dr. Hiroshi Murakami, JAXA
