Sediment Concentration, Water Velocity, and Suspended Particle Size and Settling Data to Estimate Estuarine Sediment Flux at Dumbarton Bridge, San Francisco Bay, CA from 2018 - 2019 Measurements of suspended sediment concentration, water velocity, suspended-sediment particle size, and suspended-sediment particle settling velocity were collected to estimate suspended-sediment flux and investigate sediment transport processes at Dumbarton Bridge in San Francisco Bay (NWIS station 373015122071000) from calendar year 2018 to 2019. Data were collected using: stationary and boat-mounted acoustic Doppler current meters (ADCP, a 1 MHz Nortek Aquadopp and a 1200kHz Teledyne RiverPro, respectively), four stationary and one profiling multiparameter water quality profiling sondes (YSI 6920), a stationary acoustic backscattering sensor (ABS, Sequoia LISST-ABS), a stationary laser diffraction particle size...

Benthic communities use and sometimes regulate the cycling of essential elements (for example, carbon). Benthic invertebrate taxa may also indicate acute and chronic stressors in an environment because they accumulate contaminants and can respond – sometimes dramatically - to oligotrophic and eutrophic conditions. Benthic communities affect water quality by grazing pelagic food resources and increasing the rate of nutrient regeneration through feeding and bioturbating sediments. South San Francisco Bay is a system dependent on phytoplankton as the base...
