San Francisco Bay Joint Venture
Smooth cordgrass (Spartina alterniflora), a tall grass native to the east coast, has invaded Willapa Bay, Washington, and the San Francisco Bay, California. Management with glyphosate and imazapyr can be effective, but in the San Francisco populations, applications in several sites are confined to short periods in the fall in order to protect nesting habitats of Clapper rails (Rallus longirostr...
متن کاملPolychlorinated biphenyls (PCBs) in San Francisco Bay.
San Francisco Bay is facing a legacy of polychlorinated biphenyls (PCBs) spread widely across the land surface of the watershed, mixed deep into the sediment of the Bay, and contaminating the Bay food web to a degree that poses health risks to humans and wildlife. In response to this persistent problem, water quality managers are establishing a PCB total maximum daily load (TMDL) and implementa...
متن کاملEstimates of suspended sediment entering San Francisco Bay from the Sacramento and San Joaquin Delta, San Francisco Bay, California
This study demonstrates the use of suspended-sediment concentration (SSC) data collected at Mallard Island as a means of determining suspended-sediment load entering San Francisco Bay from the Sacramento and San Joaquin River watersheds. Optical backscatter (OBS) data were collected every 15 min during water years (WYs) 1995–2003 and converted to SSC. Daily fluvial advective sediment load was e...
متن کاملAccess to diagnostic mammography in the San Francisco Bay Area.
BACKGROUND It is important to assess access to diagnostic mammography because of the high likelihood of breast cancer among women who need diagnostic evaluation. We studied access to diagnostic mammography in the Greater San Francisco Bay Area. METHODS We identified facilities that provide diagnostic mammography in nine counties in Northern California. We tried to schedule a diagnostic mammog...
متن کاملPolychlorinated biphenyl spatial patterns in San Francisco Bay forage fish.
Industrialized waterways frequently contain nearshore hotspots of legacy polychlorinated biphenyl (PCB) contamination, with uncertain contribution to aquatic food web contamination. We evaluated the utility of estuarine forage fish as biosentinel indicators of local PCB contamination across multiple nearshore sites in San Francisco Bay. Topsmelt (Atherinops affinis) or Mississippi silverside (M...
