Overview
COMEX (Canadian Ocean Microplastics Explorer) is a web-based data visualization and decision-support platform developed to support standardized microplastics monitoring, interpretation, and policy-relevant synthesis in Canada developed by Ocean Diagnostics. COMEX brings together field monitoring data, analytical results, and model-informed context into a single, accessible interface designed for researchers, regulators, Indigenous partners, and decision-makers.
The platform is a core component of a national microplastics monitoring framework co-led by Ocean Diagnostics and the National Research Council of Canada (NRC), with the goal of improving how microplastics data are collected, interpreted, and applied to environmental management.
Why COMEX Was Developed
Microplastics monitoring programs are expanding rapidly, but the resulting data are often fragmented, method-dependent, and difficult to interpret in isolation. COMEX was created to address several persistent challenges in microplastics science and policy:
- Lack of standardized interpretation across monitoring programs
- Difficulty linking raw concentration data to environmental context
- Limited accessibility of monitoring results for non-technical users
- Gaps between monitoring data and risk- or policy-relevant decision making
COMEX responds to these challenges by providing a centralized, transparent, and exploratory platform that allows users to examine microplastics data spatially and thematically, while situating observations within a broader environmental framework.
Key Features and Capabilities of COMEX
Interactive Visualization of Microplastics Monitoring Data
COMEX provides interactive maps and dashboards that allow users to explore microplastics occurrence and distribution across Canadian marine environments. Users can examine patterns across regions, sampling campaigns, and particle characteristics, supporting exploratory data analysis and hypothesis generation.
Integration with Monitoring Frameworks
Rather than functioning as a standalone data viewer, COMEX is explicitly designed to support a monitoring framework approach. This includes alignment with:
- Defined monitoring objectives
- Standardized sampling and analytical considerations
- Contextual interpretation of observed concentrations
This framework-driven design helps ensure that monitoring data are not only visible, but usable for environmental assessment and management.
Model-Informed Context for Interpretation
COMEX is designed to work alongside environmental fate and exposure models, helping users interpret observed concentrations in relation to expected environmental distributions. This approach supports evidence-based prioritization, rather than relying solely on raw concentration comparisons.
Role of COMEX in the Canadian Microplastics Monitoring Framework
COMEX is highlighted as a central tool in the Ocean Diagnostics–NRC Canada microplastics monitoring framework, which emphasizes:
- Fit-for-purpose monitoring design
- Transparency and reproducibility
- Integration of empirical data with modeling tools
- Policy relevance and scalability
Within this framework, COMEX functions as a knowledge translation and synthesis layer, bridging the gap between data generation and decision-making.

Strengths and Limitations of COMEX
Strengths
- Centralized access to Canadian marine microplastics data
- Intuitive, web-based interface suitable for diverse audiences
- Designed explicitly for monitoring and policy applications
- Supports transparency and open science principles
Limitations
- Dependent on availability and standardization of input datasets
- Not a risk assessment or threshold-setting tool on its own
- Interpretation still requires expert judgment and contextual knowledge
COMEX is best viewed as a decision-support and synthesis platform, rather than a standalone analytical or regulatory assessment tool.
Why This Resource Matters
As jurisdictions worldwide move toward routine microplastics monitoring, there is growing recognition that data visibility alone is not sufficient. Platforms like COMEX demonstrate how monitoring data can be structured, visualized, and contextualized to better support science-based environmental management and policy development.
By aligning monitoring outputs with a broader framework and making results accessible to both technical and non-technical audiences, COMEX represents an important step toward operationalizing microplastics science for real-world decision making.
