This training from the Interstate Technology & Regulatory Council (ITRC) will explore the following topics:

• An introduction to microplastics, their sources, and worldwide distribution
• The pathways through which microplastics can enter and travel in the environment and their distribution in various media (water, soil, sediment, air, and biota)
• A current look at the most common techniques and best practices for sampling and analyzing microplastics
• Potential human health and ecological risks associated with microplastics in the environment
• An overview of existing regulations related to microplastics and macroplastics at the state, federal, and international levels
• Examples of prevention and mitigation strategies and best management practices to reduce microplastics from entering the environment and the emerging technologies to abate, treat, and remediate microplastics once they exist in the environment
• Identification of data gaps and the need for further research
• Several case studies illustrating a range of current microplastics-related topics

Before the training, participants are encouraged to view the associated ITRC Microplastics Guidance Document.

NASA has developed the Satellite-based Tool for Rapid Evaluation of Aquatic Environments (STREAM), an interactive web tool that enables high-resolution (20–30 meter) monitoring of water quality in inland lakes and coastal waters across the U.S. and selected other countries. This two-part training led by NASA’s Applied Remote Sensing Training Program introduces the STREAM web tool to visualize maps of water quality parameters over lakes and coastal areas and how to use STREAM application programming interface (API) to discover and download satellite images and water quality data for a water body. The training demonstrates how to assess changes in water quality in each lake using QGIS. The training also demonstrates the application of an MDN model to estimate water quality parameters from satellite images.

The February 10 webinar will include an introduction and demonstration of STREAM. The February 17 webinar will include an introduction to a machine learning model to estimate water quality parameters based on satellite observations.
