Mercury speciation and other constituent data from deep sediment cores in Alviso Slough, South San Francisco Bay, California, 2006-16 Mercury speciation and other constituent data from deep sediment cores in Alviso Slough, South San Francisco Bay, California, 2006-16
This dataset includes mercury and other constituent concentration and physical properties data for seven deep sediment profiles (ranging from 79 cm to 214 cm in length) collected from the thalwag of Alviso Slough, a major tributary to South San Francisco Bay (California, USA). Field sampling occurred during May 2012 (4 sites) and January 2016 (3 sites). Each profile was comprised of 1-4...
Bathymetry and acoustic backscatter data of the Sacramento River, from the Feather River to Knights Landing, California in February, 2011 Bathymetry and acoustic backscatter data of the Sacramento River, from the Feather River to Knights Landing, California in February, 2011
On February 1, 2011, the USGS Pacific Coastal and Marine Science Center (PCMSC) team carried out a project using interferometric sidescan sonar to characterize the riverbed and channel banks of a 12 mile reach of the Sacramento River near the town of Knights Landing, California (River Mile 79 through River Mile 91). The project was developed in coordination with David Smith, Engineering...
Gravity cores from San Pablo Bay and Carquinez Strait, San Francisco Bay, California Gravity cores from San Pablo Bay and Carquinez Strait, San Francisco Bay, California
This data release contains information on gravity cores that were collected by the U.S. Geological Survey in the area of San Pablo Bay and Carquinez Strait, California in 1990, 1991, and 2000. Ten (10) pdf files describe gravity cores that were split, photographed, and imaged by X-rays, and another pdf file contains a core-log legend. In addition, a shapefile (sanpablo_spls.shp) provides...
San Francisco Bay Delta Bathymetric/Topographic digital elevation model (DEM) - 2016 SF Bay Delta DEM 10-m San Francisco Bay Delta Bathymetric/Topographic digital elevation model (DEM) - 2016 SF Bay Delta DEM 10-m
A high-resolution (10-meter per pixel) digital elevation model (DEM) was created for the Sacramento-San Joaquin Delta using both bathymetry and topography data. This DEM is the result of collaborative efforts of the U.S. Geological Survey (USGS) and the California Department of Water Resources (DWR). The base of the DEM is from a 10-m DEM released in 2004 and updated in 2005 (Foxgrover...

Nearshore microfossil assemblages in a Caribbean reef environment show variable rates of recovery following Hurricane Irma Nearshore microfossil assemblages in a Caribbean reef environment show variable rates of recovery following Hurricane Irma
Modern microfossil distributions reflect site-specific habitats and provide an opportunity to assess sediment transport pathways in the nearshore environment. When applied to overwash deposits in the geological record, they provide insight into sediment provenance and transport, factors important for understanding patterns of frequency and intensity of past storms and tsunamis. Modern...

The role of surges during periods of very shallow water on sediment transport over tidal flats The role of surges during periods of very shallow water on sediment transport over tidal flats
Periods of very shallow water (water depth in the order of 10 cm) occur daily on tidal flats because of the propagation of tides over very gently sloping beds, leading to distinct morphodynamical phenomena. To improve the understanding of the characteristics of velocity and suspended sediment concentration (SSC) surges and their contribution to sediment transport and local bed changes...

Selective sediment transport during Hurricane Sandy on Fire Island (New York, USA): Inferences from heavy-mineral assemblages Selective sediment transport during Hurricane Sandy on Fire Island (New York, USA): Inferences from heavy-mineral assemblages
In October 2012, Hurricane Sandy caused severe erosion on beaches and dunes of Fire Island (New York, USA). Major shoreline changes occurred with erosional dominance in the upper shoreline and aggradation in the lowermost section of the beach due to the deposition of eroded upper beach and dune sediment. Sand laminations with a high concentration of heavy minerals (“black sand...

Anthropogenic pollutants and biomarkers for the identification of 2011 Tohoku-oki tsunami deposits (Japan) Anthropogenic pollutants and biomarkers for the identification of 2011 Tohoku-oki tsunami deposits (Japan)
Organic geochemistry is commonly used in environmental studies. In tsunami research, however, its applications are in their infancy and it is still rarely used. We present results for two types of organic geochemical markers, biomarkers and anthropogenic markers, present in deposits left by 2011 Tohoku-oki tsunami on the Sendai Plain, Japan. As the tsunami inundated the coastal lowland...

Morphodynamic resilience of intertidal mudflats on a seasonal time scale Morphodynamic resilience of intertidal mudflats on a seasonal time scale
Intertidal mudflats are morphodynamic features present in many estuaries worldwide. Often located between vegetated shores and deep channels they comprise valuable ecosystems and serve to protect the hinterland by attenuating waves. Although mudflats are persistently present on yearly to decadal time scales, little is known on their morphodynamic adaptation to short‐term variations in...

The roles of flow acceleration and deceleration in sediment suspension in the surf zone The roles of flow acceleration and deceleration in sediment suspension in the surf zone
Prediction of sediment suspension in the surf zone remains elusive. We explore how suspended sediment concentration at 19 cm above the bed in the mid-surf zone during a storm is influenced by flow acceleration and deceleration. There is a tendency for higher suspended sediment concentrations during onshore flow, with decelerating onshore flows having higher concentrations than steady...
