about this issue
The 2026–2027 Marine Instruments Buyers’ Guide is eco’s annual reference to the sensors and instruments that measure the ocean, coastal waters, and the freshwater systems that feed them. This edition catalogs more than 600 instruments from 84 companies headquartered in 14 countries. The US, the UK, Germany, and Canada are home to the largest share of listed manufacturers. Since its first edition, the guide has grown by more than 50 percent.
The guide is organized into six categories: acoustic, chemical and physical, gases, multiparameter, optical, and topside. Each category opens with a specifications table for side-by-side comparison of remote and autonomous operation, software, onboard data storage, data transfer, communication, and power. Full product descriptions follow each table. Chemical and physical instruments make up the largest category with 192 listings, followed by acoustic with 132 and optical with 117.
The Instrument Showcase takes a closer look at individual technologies throughout the guide. Thank you to our contributors: ClearWater Sensors, Pro-Oceanus, PEBL CL, NexSens, PyroScience, Okeanus, Teledyne Valeport, and Nauticus Robotics.
