Optical water quality of a blackwater river estuary: the Lower St. Johns River, Florida, USA
This paper reports measurements of absorption and scattering coefficients in relation to standard water quality measurements in the St. Johns River (Florida, USA), a blackwater river in which phytoplankton chlorophyll and non-algal particulates as well as colored dissolved organic matter (CDOM) contribute substantially to the inherent optical properties of the water. Extremely high concentratio...

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
15 صفحه اولCharacterization of shallow groundwater quality in the Lower St. Johns River Basin: a case study.
Characterization of groundwater quality allows the evaluation of groundwater pollution and provides information for better management of groundwater resources. This study characterized the shallow groundwater quality and its spatial and seasonal variations in the Lower St. Johns River Basin, Florida, USA, under agricultural, forest, wastewater, and residential land uses using field measurements...
متن کاملOsmoregulation of the Atlantic stingray (Dasyatis sabina) from the freshwater Lake Jesup of the St. Johns River, Florida.
The goals of this study were to (1) measure plasma osmolytes and rectal gland weights of a freshwater (FW) Atlantic stingray (Dasyatis sabina) population in the St. Johns River, Florida, and (2) determine how these parameters change after acclimation to seawater (SW). We hypothesized that the FW D. sabina may show physiological divergence from marine D. sabina, because the FW individuals reprod...
متن کاملEffect of nutrients and salinity pulses on biomass and growth of Vallisneria americana in lower St Johns River, FL, USA
We determined the interactive effects of nutrient loading and salinity pulsing on Vallisneria americana Michx., the dominant submerged aquatic vegetation species in the lower St Johns River (LSJR), FL, USA, and its associated algal community. Five hundred and ninety 6-inch diameter intact plant plugs of Vallisneria were collected from the LSJR in March 2003 and transported to US Geological Surv...
