Water level, flow velocity, temperature, salinity, and turbidity were measured in a breach constructed in a flood-protection levee surrounding a restored former agricultural area in Port Susan, Washington, USA, near the mouth of the Stillaguamish River. Data were collected in a breach known as PSB1 at 15-minute intervals from March 21, 2014 to July 1, 2015 using a SonTek Argonaut-SW current meter, an In-Situ Aqua TROLL 200 pressure, conductivity, and temperature sensor, and an FTS DTS-12 turbidity sensor.

Tidal water discharge within two breaches constructed in a former flood-control levee of a restored agricultural area in Port Susan, Washington, was measured repeatedly during several tidal cycles. Measurements were made on March 27, 2014, April 16, 2014, May 18, 2014, and May 29, 2014 at breach PSB1, and on May 29, 2014 at breach PSB2. These data were collected using a boat-mounted Teledyne RDI RiverRay 600 kHz acoustic Doppler current profiler (ADCP) or a Teledyne RDI StreamPro 2000 kHz ADCP, depending on date. ADCP transect data were collected and initially reviewed using WinRiver II software and reprocessing and final review was completed with QRev software.

Bottom-landing and floating platforms with instrumentation to measure currents, waves, water level, optical turbidity, water temperature, and conductivity were deployed at four locations in Bellingham Bay, Washington, USA. Platforms were deployed in three separate periods: July 30, 2019–November 14, 2019, November 19, 2019–February 5, 2020, and January 22, 2021–April 13, 2021. These data were collected to support studies of sediment delivery, transport, deposition, and resuspension in this Pacific Northwest estuarine embayment.

Time-series data of water surface elevation, wave height, and water column currents, temperature, salinity, and acoustic seabed images were acquired for 38 days between 9 May and 15 June, 2013 in the mouth of the Columbia River, Oregon and Washington.

Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at three locations in the Sacramento-San Joaquin Delta. Data were collected in Lindsey Slough in April 2017, and Middle River and the Mokelumne River in March 2018. Data files are grouped by location. At each of the three sites, data were collected at stations outside and within patches of vegetation, to determine how submerged invasive vegetation influences tidal currents and suspended-sediment concentration. The Table below shows the data types collected at each station, and classifies stations as Vegetated (V) or Unvegetated (U). These data were collected as part of a study of the effects of invasive aquatic vegetation on sediment transport in the Sacramento-San Joaquin Delta. At times, vegetation caught on instrument frames (both within and outside patches) compromised data quality. Users are advised to check data quality carefully, and to check metadata and instrument information, as individual instrument deployment times vary.

Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at shallow subtidal and intertidal sites in Corte Madera Bay and San Pablo Bay National Wildlife Refuge (SPNWF) in San Francisco Bay, CA, as well as on the marsh plain of SPNWF marsh and in a tidal creek and on the marsh plain of Corte Madera Marsh, in 2022 and 2023. Data files are grouped by station, San Pablo subtidal, San Pablo intertidal, San Pablo marsh, Corte Madera subtidal, Corte Madera intertidal, Corte Madera marsh, or Corte Madera tidal creek, then by instrument type. At most stations there were periods of low water when sensors were no longer submerged, resulting in spurious data. In addition, most instruments experienced some degree of biofouling, particularly at the subtidal and intertidal stations. The subtidal stations also occasionally show signs of platform rocking or movement due to strong water flow, and/or from accidental fisher/boater interference. Users are advised to assess data quality carefully, and to check the metadata for instrument information, as platform deployment times and data-processing methods varied.

Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, suspended particle size, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at two locations in south San Francisco Bay. Data were collected in the channel (one platform) and in the shallows (three co-located platforms) for 2 weeks in July 2020. Data files are grouped by site (channel or shallows). Each site contained instrumentation to collect the data listed, with slight instrument and setup variations between the two sites due to logistics. Users are advised to assess data quality carefully, and to check metadata for instrument information, as platform deployment times and data-processing methods varied.

Time-series data of water surface elevation, waves, currents, temperature, and turbidity collected between November 2017 and March 2018 off the west coast of Maui, Hawaii, USA. The data are available in NetCDF format, grouped together in zip files by instrument site location. These data support a modeling study on the effects of potential watershed restoration on decreasing sediment loads to adjacent reefs (Storlazzi and others, 2023).
