ISO 35103:2017

Overview

ISO 35103:2017 - Petroleum and natural gas industries - Arctic operations - Environmental monitoring defines requirements, specifications and guidance to ensure environmental monitoring in the offshore Arctic is fit for purpose. It applies across the full lifecycle of Arctic oil and gas activity - from licence acquisition, exploration, design, construction and commissioning through operation, decommissioning and restoration. The standard covers the marine and estuarine offshore environment north of the Arctic Circle (and sub‑Arctic sites with Arctic‑like conditions), addressing physical, chemical and biological components. It includes monitoring for normal, abnormal and emergency conditions at near‑field, far‑field, transboundary and regional scales (global monitoring is excluded). Onshore (terrestrial) monitoring is only included when directly related to offshore developments.

Key topics and technical requirements

• Programme design and objectives: Define clear monitoring objectives, programme specifications and adaptive adjustment steps.
• Spatial and temporal scales: Establish near‑field, far‑field, regional and transboundary sampling strategies and align frequency with seasonal Arctic variability.
• Baseline conditions: Develop robust baseline datasets to distinguish natural variability from project‑related impacts.
• Parameters and measurement: Select physical, chemical and biological parameters, set accuracy and detection limits, and specify units and associated measurements.
• Sampling and analytical methods: Standardize sampling protocols, laboratory analyses and quality assurance/quality control (QA/QC).
• Toxicity testing and modelling: Include marine toxicity tests and environmental modelling to inform impact assessment and monitoring interpretation.
• Statistical methods and reporting: Apply appropriate statistics, document results, and include costs and reporting requirements.
• Arctic operational factors: Address remote logistics, low temperatures, ice dynamics, extreme seasonality, endemic species, and integration of local and traditional knowledge.
• Emergency and abnormal conditions: Require monitoring plans for spills, discharges and other incidents, including rapid response sampling.

Applications and who uses it

ISO 35103:2017 is practical for:

• Offshore oil & gas operators designing environmental monitoring programmes in Arctic waters
• Environmental consultants and monitoring contractors developing sampling and QA/QC plans
• Regulators and permitting authorities reviewing monitoring commitments and compliance
• Laboratories performing Arctic‑specific analyses and toxicity tests
• Project managers, engineers and decommissioning teams planning lifecycle monitoring
• Stakeholders and communities (including indigenous groups) seeking transparency on monitoring design and reporting

Related standards

ISO 35103:2017 is intended to be used alongside relevant ISO management system standards and industry guidance for environmental, quality and health‑safety practice. Use it to ensure Arctic offshore monitoring is scientifically robust, legally defensible and operationally practical.
