What is the interval for data to be acquired from the SLDMB?

• A. Every 5 minutes
• B. Every 15 minutes
• C. Every 30 minutes
• D. Every 60 minutes

Answer: (B)

Regular data collection intervals are chosen to balance how often you need information with how much power, memory, and bandwidth the system can support. For the SLDMB, a 15-minute interval provides enough temporal detail to track typical sea-state changes, tides, and environmental parameters without draining the battery or flooding the transmission link with data. Sampling every five minutes would increase data volume and power use with diminishing returns for most mission needs. Waiting 30 minutes or an hour would reduce the ability to resolve shorter-term events and rapid shifts in conditions, making it harder to capture meaningful variability. Thus, a 15-minute cadence is the practical compromise that preserves data quality while staying within resource limits.
