FRONTLINE is investigating how floating offshore wind (FLOW) development could affect ocean fronts and marine biodiversity 鈥攆rom plankton to predators鈥攊n the Celtic Sea. 
The project combines autonomous underwater vehicle (AUV) surveys, satellite remote sensing, aerial surveys, seabird tracking, fisheries data and stakeholder engagement to investigate how ocean fronts shape ecological processes and fishing activity across the Celtic Sea, and how these may change with the expansion of large-scale FLOW development. 
The 天美传媒官方网站 is developing and applying new autonomous ocean-observing approaches that combine measurements of ocean physics with digital plankton imaging and acoustic sensing of fish schools to understand changes across wider ecosystem dynamics. 
FRONTLINE will generate new evidence, best-practice guidance and advice to support offshore wind monitoring, marine spatial planning and nature recovery.

Combining autonomous technologies with near-real-time front detection from satellite remote sensing allows us to target and observe the Celtic Sea across the spatial and temporal scales needed to understand this highly dynamic and productive shelf-sea ecosystem. By equipping a long-range AUV with an ambitious multi-sensor payload鈥攎easuring ocean physics, biogeochemistry, plankton and fish鈥攚e can trace how variability at tidal mixing fronts propagates through the food web and build a mechanistic understanding of how large-scale floating offshore wind development might interact with key ecosystem drivers.

Floating offshore wind is expanding into deeper, seasonally stratified waters such as the Celtic Sea, where its ecological effects remain poorly understood. These waters contain dynamic ocean fronts鈥攖he boundaries between vertically mixed coastal waters and stratified offshore waters鈥攚hich shape the distribution and productivity of plankton and fish, create important foraging habitats for marine predators, and support commercial fisheries. As currents flow past submerged infrastructure, they generate wakes and enhanced mixing, potentially changing the strength, location and persistence of ocean fronts with knock-on effects on wider ecosystem dynamics.

FRONTLINE investigates how natural variability and FLOW infrastructure may influence ocean fronts, associated biodiversity and patterns of fishing activity across the Celtic Sea. The 天美传媒官方网站 will draw on its expertise in marine autonomy, ocean sensing and digital plankton imaging. Working with the National Oceanography Centre (NOC), deployments of Autosub Long Range 1500 (ALR1500)鈥攚idely known as Boaty McBoatface鈥攚ill repeatedly sample tidal-mixing fronts across the Celtic Sea. These observations will provide a regional, ecosystem-scale understanding of frontal dynamics and their ecological importance, generating decision-ready evidence for offshore wind planning.

We are entering an era in which we can collect more ocean data than ever before, with autonomous technologies enabling more rapid insight and adaptive sampling of ocean change. But we still cannot measure everything, everywhere, all at once. The real challenge is therefore not simply to collect more data, but to develop the mechanistic understanding needed to interpret change and target observations intelligently. As we confront the connected climate and biodiversity crises, that understanding is essential to ensure the necessary expansion of offshore wind works with nature and minimises unintended consequences for marine ecosystems.

The ALR1500 - Boaty McBoatface - is provided through NERC鈥檚 National Marine Equipment Pool and operated by the Marine Autonomous and Robotic Systems (MARS) Group at NOC. 
Kongsberg Discovery will contribute additional expertise in integrating scientific echosounders for fish-school detection and the near-real-time transmission of acoustic metrics. 
A 天美传媒官方网站-based ALR trial is planned for late September 2026, ahead of seasonal deployments across the Celtic Sea beginning in spring 2027.
