Identification and Quantification of the Temporal and Spatial Scales of Variability in Particulate and Dissolved Material Associated with Specific Land-use Activities in the Penobscot River System

Abstract

LONG-TERM GOALS. 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 episodic events) and spatially (from the source into coastal waters). OBJECTIVES. Our main objectives are to:. o develop optical proxies for biogeochemical properties (i.e. algal pigments, total suspended solids, particulate and dissolved organic carbon) that can be applied to in situ optical observations to obtain highly resolved temporal estimates of those biogeochemical properties o identify optical proxies for land use activities (e.g. specific fluorophores linked to agricultural activities or wetlands) o quantify the time and space scales for which these proxies behave as conservative tracers in the Penobscot River, Penobscot Bay and ultimately in the coastal waters of the Gulf of Maine.
