Sediment deposition measured along a transect extending from the edge of a tidal creek into the interior of the low marsh of a mainland marsh site on the Eastern Shore of Virginia. (a) Average deposition collected on sediment traps during individual tidal cycles; bars indicate standard error. (b) Deposition in sediment traps over three 2-week periods, divided by the number of tides flooding the marsh during those time intervals. Regular tidal flooding characterized the 17 Jun–2 Jul sampling period (12 tidal cycles). A small northeaster (2 tidal cycles out of 13) occurred during the 21 May–3 Jun sampling period, and a larger northeaster (9 tidal cycles out of 12) occurred during the 2–17 Jun sampling period. (c) Deposition above a marker horizon during a 2-week period that included a very large northeaster lasting from 4 to 9 Feb 1998 (nine tidal cycles). After Christiansen (1998).
