Temporal and Spatial Scales of Terrestrially-derived Particulate and Dissolved Materials in the Penobscot River System: Quantifying Conserved and Non- conserved Optical Properties and Transformations within the Estuary
نویسندگان
چکیده
Coastal waters represent the commingling of offshore marine and terrestrial surface source waters and therefore are naturally complex and variable. Our long term goal is to establish observational and modeling approaches to predict sources and scales of variability in the source waters, particularly those related to land use activities in upstream watersheds, from observations and measurements in the coastal waters.

Identification and Quantification of the Temporal and Spatial Scales ff Variability in Particulate and Dissolved Material Associated with Specific Land-Use Activities in the Penobscot River System
The long-term goals of this project are to identify and quantify specific optical and chemical characteristics of the colored particulate and dissolved fractions of the Penobscot River water system that are associated with defined land use activities (land use proxies), and to determine the scales of variability over which these proxies can be detected both temporally (i.e. seasonal and episodi...
متن کاملSpatial and Temporal Variation in Copepod Community in the Helleh River Estuary – South Coast of Iran, Persian Gulf
Copepods are the main zooplankton assemblages in most tropical and semi-tropical estuaries. In this research, copepod population dynamics were investigated in Helleh River estuary, Persian Gulf during four seasons beginning from summer 2011 to spring 2012. Samples were taken using plankton net with mesh size of 140 µm and vertical towing from 5 fixed-stations in mid-season. Results showed that...
متن کاملOptical 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...
متن کاملSpatio-temporal changes of water quality variables in a highly disturbed river
Quality of river varies widely depending on the land use in the catchment and environmental factors. Many rivers in developing countries are unhealthy because they contain harmful physical, chemical and biological agents. Zanjanrud River, located in Zanjan Province, Iran, where recently faced human intervention needs a regular monitoring from upstream to downstream for sustainable management. H...
متن کاملSeasonal variability in water chemistry and sediment characteristics of intertidal zone at Karnafully estuary, Bangladesh
The Karnafully is one of the most important rivers due to its profound influence on water chemistry and sediment characteristics. The present study intended to assess the quality of water and sediment from intertidal zone of this river in respect to the pollution index. Seasonal water and sediment samples were collected during four seasons (Monsoon, post-monsoon, winter, and pre-monsoon) of 201...
