Experimental islands and saltmarsh enclosed plots were created in the back barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog. Sediment samples for the determination of pH, water content and loss on ignition were taken bi-/monthly in surface sediments (0-3 cm depth). Samples were measured in the laboratory within two months after sampling.7.7156087.72673953.75679453.762656off Spiekeroog, German Bight, North SeaGerman Research Foundationhttps://doi.org/10.13039/501100001659379417748FOR 2716: Spatial community ecology in highly dynamic landscapes: from island biogeography to metaecosystems
