    • Topographic data from two marshes and adjacent shallows in Northern San Francisco Bay, California, 2022-2023

    Metadata Updated: September 16, 2025

    Topographic data were collected in the Corte Madera Marsh, San Pablo National Wildlife Refuge Marsh, and at the time-series stations in the shallows adjacent to each marsh in Northern San Francisco Bay between April 2022 and September 2023. The topographic data were acquired using global satellite navigation system receivers that were either mounted on backpacks and hiked over the marsh surface or mounted on a survey rod held shipside against a deployed platform or on the water surface. Sometimes an additional staff was used in conjunction with the shipside survey rod to reach the platform, which we refer to as an integrated collection method.
