New wave-powered system extends AUV mission duration

Divers and ocean researchers can benefit from longer AUV missions with reduced maintenance needs.

Researchers-students are currently developing autonomous underwater vehicles for a competition. The system uses an oscillating water column and a Wells turbine to convert wave energy into electricity. It was tested in controlled environments and showed potential for significant performance improvements.

Depth Influences Recovery Time in Sea Lions

Divers and ocean researchers may gain new insights into how pressure affects recovery times in marine animals.

Using more than 800 000 dives from five sea lion species across 18 colonies spanning tropical to subpolar waters, we quantified how post-dive duration (PDD) scales with dive depth and duration and assessed whether this pattern aligns with metabolic recovery interpretations or instead points to depth-linked constraints. We found that PDD increases primarily and linearly with depth. This pattern is consistent across species despite differences in body size and foraging habits. The findings suggest that pressure-related inert-gas loading, rather than metabolic recovery, primarily influences surface intervals in these animals.

  • Researchers analyzed over 800,000 dives from five sea lion species across various regions.
  • Post-dive duration mainly increases with depth, not dive duration itself.
  • Findings suggest pressure-linked inert-gas management shapes recovery times.
