Long-term trends, current status, and transitions of water quality in Chesapeake Bay

Status and Trends in Water Quality and Living Resources in the Virginia Chesapeake Bay: James River

Notice During the mid-1990's the Chesapeake Bay Program's (CBP) Analytical Methods and Quality Assurance Workgroup recommended that the CBP adopt new and more accurate analytical methods for measuring total nitrogen, dissolved inorganic nitrogen, total phosphorus and dissolved inorganic phosphorus. An recent examination of scatterplots of these parameters suggested that the adoption of these ne...

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...

Seasonal and Long-term Trends in the Water Quality of Florida Bay (1989-l 997)

Analysis of 6 yr of monthly water quality data was performed on three distinct zones of Florida Bay: the eastern bay, central bay, and western bay. Each zone was analyzed for trends at hrtra-annual (seasonal), interammal (oscillation), and long-term (monotonic) scales. The variables TON, TOC, temperature, and TN : TF’ ratio had seasonal maxhna in the summer rainy season; APA and Chl a, indicato...

Long-Term Trends in Chesapeake Bay Seasonal Hypoxia, Stratification, and Nutrient Loading

A previously observed shift in the relationship between Chesapeake Bay hypoxia and nitrogen loading has pressing implications on the efficacy of nutrient management. Detailed temporal analyses of long-term hypoxia, nitrogen loads, and stratification were conducted to reveal different within-summer trends and understand more clearly the relative role of physical conditions. Evaluation of a 60-ye...
