**Key Insight:** The article discusses a successful subsea harvester operation in the Pacific Ocean, which is more than 13,000 feet below the surface. This operation successfully extracted copper, manganese, cobalt, and nickel from rock nodules.

Mining the deep ocean More than 13,000 feet below the surface of the Pacific Ocean, a more-than-70- ton machine trundled like a tank on its caterpillar tracks for a tenth of a mile — sucking up potato-sized nodules of rock packed with copper, manganese, cobalt and nickel. It was 2022, and that pilot run of a subsea harvester by a Canadian business, The Metals Company, was pronounced a success. link: https://lnkd.in/gJaWK38n

GasGx Editorial Insight
**Key Insight:** The article discusses a successful subsea harvester operation in the Pacific Ocean, which is more than 13,000 feet below the surface. This operation successfully extracted copper, manganese, cobalt, and nickel from rock nodules.

[Body Paragraph 1: Analysis of the market/tech situation]
The article highlights the potential for off-grid power generation and cryptocurrency mining economics in the deep ocean mining sector. However, it also mentions regulatory tightening in Alberta, which could impact the profitability of non-TIER compliant engines.

[Body Paragraph 2: The specific operational implication]
Given the high cost of compliance and the potential for regulatory changes, gas miners need to consider their energy efficiency and uptime when planning their operations. A GasGx LCOE Calculator can help them forecast their costs accurately, while a GasGx Smart Monitoring System can alert them to any potential issues before they become major problems.

[GasGx Take:] To address the regulatory challenges and ensure compliance, gas miners should leverage GasGx's LCOE Calculator to accurately forecast their costs and use its Smart Monitoring System to detect any potential issues before they become major problems.
