One Wet Winter Can Shake Up San Francisco Bay’s Invasive Species（图）
One Wet Winter San Francisco Bay Invasive Species
2017/12/19
For many Californians, last year’s wet winter triggered a case of whiplash. After five years of drought, rain from October 2016 to February 2017 broke more than a century of records. In San Francisco ...
Dynamics of barotropic low-frequency fluctuations in San Francisco Bay during upwelling
Hydrodynamic modeling Low-frequency fluctuations San Francisco Bay
2015/6/30
Observations of wind, surface elevations, and currents in San Francisco Bay during the 1999 upwelling season are analyzed to understand the dynamics of low-frequency currents in upwelling-dominated es...
Role of phytoplankton in mercury cycling in the San Francisco Bay estuary
Role of phytoplankton he San Francisco Bay estuary
2014/4/17
To study the role of phytoplankton in mercury cycling, we measured methylmercury (MeHg) and total
mercury (HgT) in surface waters during the spring 2003 phytoplankton bloom in San Francisco Bay. Cond...
Temperature Anomalies Between San Francisco and Honolulu, 1966–1974, Gridded by an Objective Analysis
Temperature Anomalies San Francisco Honolulu
2009/2/23
Over the eight years of expendable bathythermograph observations from merchant ship transits between San Francisco and Honolulu have been analyzed to determine the nature of subsurface temperature ano...
Surface Salinity and Temperature on the San Francisco-Honolulu Route June 1966-December 1970 and January 1972-December 1975
Surface Salinity San Francisco-Honolulu Route Temperature
2009/2/19
Time-distance distributions of surface salinity and temperature, and their anomalies, were investigated for a region of weak meridional currents, using 8.5 years of observations by merchant ships on t...
Monthly Mean Sea Level Fluctuations at Honolulu and San Francisco and the Intervening Geostrophic Currents
Monthly Mean Sea Level Fluctuations Honolulu San Francisco Intervening Geostrophic Currents
2009/2/10
Monthly mean dynamic topography (0/500 db) along the great-circle section between Honolulu and San Francisco reveals four principal current regimes: a northerly flow immediately adjacent to the Hawaii...
Low-Frequency Variations in Sea Level and Currents in South San Francisco Bay
Low-Frequency South San Francisco Bay Sea Level
2009/2/7
In order to examine physical process in the subtidal time range, sea-level and current meter data for south San Francisco Bay (South Bay) were filtered using a low-pass digital filter to remove tidal ...
Rossby Wave Analysis of Subsurface Temperature Fluctuations along the Honolulu-San Francisco Great Circle
Rossby Wave Subsurface Temperature Fluctuations Honolulu-San Francisco Great Circle
2009/1/22
Seven years of XBT observations collected between Honolulu and San Francisco reveal subsurface temperature fluctuations with strong, in-phase vertical coherence and fair horizontal coherence over 1000...
Structure and Flow-Induced Variability of the Subtidal Salinity Field in Northern San Francisco Bay
Structure Flow-Induced Variability Subtidal Salinity Field Northern San Francisco Bay
2008/6/20
The structure of the salinity field in northern San Francisco Bay and how it is affected by freshwater flow are discussed. Two datasets are examined: the first is 23 years of daily salinity data taken...
Contrasting biogeochemistry of six trace metals during the rise and decay of a spring phytoplankton bloom in San Francisco Bay
biogeochemistry six trace metals during the rise decay of a spring phytoplankton bloom San Francisco Bay
2014/4/22
The spring 2003 phytoplankton bloom in South San Francisco Bay (South Bay) affected the cycling of Mn, Co, Zn, Ni, and Pb, but not Cu. We followed this diatom bloom for 2 months, capturing a peak in c...
Evaluating the biogeochemical cycle of selenium in San Francisco Bay through modeling
biogeochemical cycle selenium in San Francisco Bay
2014/5/5
A biogeochemical model was developed to simulate salinity, total suspended material, phytoplankton biomass, dissolved selenium concentrations (selenite, selenate, and organic selenide), and particulat...
Nitrogen sources and cycling in the San Francisco Bay Estuary: A nitrate dual isotopic composition approach
Nitrogen sources cycling San Francisco Bay Estuary nitrate dual isotopic composition
2014/5/4
We used the dual isotopic composition of nitrate (δ15N and δ18O) within the estuarine system of San Francisco (SF) Bay, California, to explore the utility of this approach for tracing sources and cycl...
We constructed water, salt, and nutrient budgets for San Francisco Bay and used them to analyze the net biogeochemical performance of the bay. The bay was subdivided into three sectors, North, Central...
Long-term changes in apparent uptake of silica in the San Francisco estuary
Long-term changes apparent uptake silica San Francisco estuary
2014/5/9
Silica distributions in estuaries can be used to infer uptake, particularly that due to production by diatoms. I used data from two long-term monitoring programs to infer long-term patterns of diatom ...
Sediment–water exchange of total mercury and monomethyl mercury in the San Francisco Bay–Delta
Sediment–water exchange monomethyl mercury
2014/5/19
Five field trips were conducted in the San Francisco Bay–Delta between May 2000 and October 2001 to investigate the sediment–water exchange of total mercury (Hg) and monomethyl mercury (MMHg). S...
