Webinar 1: Nov. 30 – Dec. 2, 2021 (Mapping Seagrass by Optical Sensors)
Webinar 2: Dec. 14 – 16, 2021 (Monitoring and Assessment of Water Quality by Ocean Color Remote Sensing)
Introduction
CEARAC organized the 5th NOWPAP remote sensing training, our first webinar of remote sensing data analysis training: Webinar 1 (mapping seagrass by optical sensors) from November 30 to December 2; and Webinar 2 (monitoring and assessment of water quality by ocean color remote sensing) from December 14 to 16, 2021.
For Webinar 1, participants learned key factors for accurate mapping of seagrass habitats and got familiar with the Seagrass Trainer and the Seagrass Mapper, both of which were developed by CEARAC for mapping seagrass grounds in the NOWPAP region, while for Webinar 2, participants were introduced to several tools developed by CEARAC to help protect the coastal marine environment. One of the tools is the Global Eutrophication Watch running on Google Earth Engine. It is used for rapid screening of coastal eutrophication with satellite-derived chlorophyll data. The other is the online match-up tool that helps improve satellite data product algorithms through collection of ground truth data.
Objectives
To contribute to capacity building, targeting at postgraduate students, young professional researchers and coastal managers (including local government officers) working in the fields of marine sciences and coastal-zone management in the Northwest Pacific Region and adjacent area while introducing useful tools of CEARAC to monitor and assess the status of the coastal environment by processing and analyzing satellite imagery.
