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 ...

A research team, led by University of Delaware professor Wei-Jun Cai, has identified a zone of water that is increasing in acidity in the Chesapeake Bay.The team analyzed little studied factors that p...
Mapping Surface Currents in Monterey Bay With CODAR-Type HF Radar
Mapping Surface Currents Monterey Bay CODAR-Type HF Radar
2015/8/10
High-frequency (HF) radar measurements have been employed around Monterey Bay, CA, to measure ocean surface currents since February 1992. The first array consisted of two older-generation CODAR instru...
综合研究1985-2015年美国Tampa Bay流域景观生态风险态势研判
景观格局 生态风险 空间分析 Tampa Bay流域
2016/12/22
探究坦帕湾流域景观生态风险的时空变化态势,为中国港湾流域开发利用与保护规划提供科学借鉴。[方法] 以1985,1995,2005及2015年4个时期的TM/OLI遥感影像为主要数据源,结合土地利用数据,构建景观生态风险格局演变模型,对美国坦帕湾流域景观格局及生态风险的时空特征进行了分析。[结果] (1) 研究期间,坦帕湾流域人工景观面积明显大于自然景观面积。(2) 1985年,坦帕湾流域景观低、较...
Coastal Ocean Physics and Red Tides:An Example from Monterey Bay, California
Coastal Ocean Physics Red Tides Example from Monterey Bay California
2015/7/27
Dense accumulations of certain phytoplankton make the ocean appear reddish. Some of these "red tides" poison marine life and negatively impact coastal fisheries and human health. Complex variability i...
Less than a week after returning to my home in Halifax from Y2K celebrations in Banff, I boarded an airplane to join the JOIDES Resolution in Fremantle, Australia, with the ultimate destination of Pry...
Rapid Subsurface Ocean Warming in the Bay of Fundy as Measured by Free-Swimming Basking Sharks
Measured Free-Swimming Basking Sharks
2015/7/17
It is widely recognized that the western North Atlantic has recently warmed very rapidly. Sea surface temperatures (SST) in 2012 were measured to be 1–3°C higher than the 1982–2011 average (Mills et a...
A Decade of Directly Measured Sediment N2 Fluxes:What Can Narragansett Bay Tell Us About the Global Ocean Nitrogen Budget?
Directly Measured Sediment N2 Fluxes Narragansett Bay Global Ocean Nitrogen Budget
2015/7/17
The tight coupling between nitrogen and carbon cycling has important implications for global climate. These two cycles are under growing anthropogenic pressures (e.g., warming temperatures, changes in...
Power Estimates Associated With Internal Tides From the Monterey Bay Area
Monterey Bay Area Internal Tides
2015/7/14
Numerical modeling has proven to be a useful method for simulating internal tides within the coastal ocean. Monterey Bay is a location that experiences energetic semidiurnal internal tides, and they a...
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...
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound. Scientis...
Nutrient loading and meteorological conditions explain interannual variability of hypoxia in Chesapeake Bay
Nutrient loading meteorological conditions Chesapeake Bay
2014/4/2
We use geostatistical universal kriging and conditional realizations to provide the first quantitative estimates,
with robust estimates of uncertainties, of the seasonal and interannual variability i...
