A coral reef acoustic ecologist records 180 minutes of reef soundscape. Fish vocalizations occur every 4 minutes, crustaceans every 6 minutes, and competition events every 9 minutes. How many total acoustic events (vocalizations and competition) are detected, assuming no simultaneous overlap?

**A coral reef acoustic ecologist records 180 minutes of reef soundscape. Fish vocalizations occur every 4 minutes, crustaceans every 6 minutes, and competition events every 9 minutes. How many total acoustic events (vocalizations and competition) are detected, assuming no simultaneous overlap?** Acoustic monitoring of coral reefs has become a powerful tool for understanding marine ecosystems. Recent recordings from a marine acoustic ecologist capture 180 minutes of reef sound, revealing rhythmic patterns driven by fish calls, crustacean clicks, and brief competition bursts. These events offer vital clues about reef health, biodiversity, and daily biological rhythms—making this type of sonic research a growing focus in ocean conservation. This pattern—fish vocalizations every 4 minutes, crustaceans every 6 minutes, and competition moments every 9 minutes—can be modeled to estimate total acoustic activity. By analyzing these intervals, scientists apply basic arithmetic to determine occurrences without assuming overlap, ensuring clean, accurate counts for ecological analysis. **Mapping Reef Rhythms: How Many Total Events?**
