Calibration drift in low-cost tide gauges
How far pressure-based gauges wander between calibrations, and whether a co-located reference catches it in time.

Drift bound under weekly reference correction
With a co-located reference read at least weekly, pressure-gauge drift stays under 4 mm over twelve weeks for six of seven units.
summer deployment, sheltered harbor, seven units; not a winter or open-coast result
Biofouling explains the seventh unit
The one unit that exceeded the bound had a blocked vent path.

relations · one mark per relation type
Twelve weeks of six-minute reference readings, gaps under one hour.
The winter 2025 deployment exceeded the bound on three of five units.
Unit 7's housing was replaced before inspection; the vent state is not on record.

theorems · definition, theorem, proof, formula, conjecture
A gauge is bounded over a window if its reference-corrected residual never exceeds b.
Under weekly correction, the residual is bounded by the largest single-week drift.
Each correction resets the residual; between corrections it can grow by at most one week's drift.
Daily correction does not improve the bound when drift is monotone within a week.

Drift is not the problem. Uncorrected drift is. A weekly reference read is enough for six of seven units; the seventh is a housing story.
