Bottom-water record

The logger records underwater between visits. After retrieval, each dated batch joins the permanent lake archive with its original observation times.

Slow data, worth waiting for

Continuous below. Updated by hand.

The public page will not pretend this logger is live. Each import will retain the original observation times and the date the batch was retrieved.

Built before the first reading

Every range is ready.

The same 24-hour-to-lifetime experience is already waiting underneath. As batches arrive, shorter ranges reveal daily movement and longer ones build toward seasonal and year-over-year comparisons.
