Onboard Columbia University’s research vessel, the R/V Marcus G. Langseth, Chief Science Officer Cody Bahlau serves as the vital link connecting scientists, crew, and shore operations to advance oceanographic and geophysical research while ensuring safety and collaboration.
- Coordinates science, crew, and safety on a global research vessel
- Supports multi-disciplinary studies on ocean floor and tectonics
- Engages public and students with live insights from sea expeditions
What happened
Cody Bahlau, chief science officer aboard the R/V Marcus G. Langseth operated by Columbia University’s Lamont-Doherty Earth Observatory, plays a pivotal role in facilitating cutting-edge oceanographic research. He bridges the gap between on-board scientists, the vessel crew, and shore-based operations to ensure research goals are met effectively and safely. His responsibilities span managing equipment deployments, coordinating data acquisition, and overseeing safety protocols during expeditions that can last from two to nearly two months.
Recently, the Langseth completed a notable 3D seismic survey expedition along the East Pacific Rise, revisiting a study location first surveyed in 2008. Using advanced seismic technology involving multiple cables towed behind the ship, the team gathered new data offering a time-lapse view of ocean floor changes, opening fresh pathways for understanding mid-ocean ridge dynamics and tectonic shifts beneath the waves.
Why it feels good
The work aboard the Langseth exemplifies a unique blend of scientific inquiry, operational teamwork, and exploration. For Bahlau, the job is rewarding because it combines his lifelong love of geology and mapping with his practical knowledge of remote data acquisition and project management. His role supports a wide range of researchers—from students to PhD holders—helping them realize objectives that deepen our understanding of the planet’s underwater geology and vital ocean processes.
Beyond the science itself, Bahlau also enjoys fostering connections to classrooms on land, demystifying ocean research for students and bringing the excitement of discovery to younger generations. This engagement helps build broader appreciation for the value of marine science and inspires future explorers and scientists.
What to enjoy or watch next
Currently, the Langseth is underway, having traveled from San Diego to Hawaii and the Marshall Islands, where crew transitions occurred. A new scientific party including members from NOAA is now directing the ship’s course from the Marshall Islands onwards toward Costa Rica and Panama City. From there, Bahlau will rejoin the vessel for a STEM outreach-focused journey to Savannah, Georgia, exploring additional oceanographic questions as the ship cruises through the Caribbean.
Sea enthusiasts and science lovers can look forward to live streaming events and real-time updates from the Langseth, offering a rare glimpse into oceanographic expeditions and the ongoing efforts to unravel the secrets hidden beneath the sea. Following these missions highlights the vital blend of technology, expertise, and passion driving modern marine research.
