A relatively small self‐contained sediment trap with a timed closing system was deployed in Dabob Bay, Washington, for 1 year. Samples were collected representing 326 trap exposure days. An in situ calibration was obtained by comparing the capture and retention of unsupported 210 Pb by the traps with the steady state accumulation rate of unsupported 210 Pb in the underlying bottom. The efficiency of the traps to collect a representative sample of the sedimenting material is 118%.
