“…These methods were employed in lacustrine environments more than fluvial systems (Hutchinson, 1957), and were adopted by other studies looking at average river water concentrations globally (Livingstone, 1963). Method improvements in the 1960s involved oxidizing samples to CO 2 and detecting with infrared analyzers (Menzel and Vaccaro, 1964;Vanhall et al, 1963). An early study using these methods on the Amazon River reported concentrations of dissolved organic carbon (DOC) of ~3.5 mg L −1 , or 3-4× greater than surface seawater (Williams, 1968).…”

“…Samples were homogenized, further acidified, purged with an inert gas to remove inorganic carbon, and combusted at high temperature (950 "C). The evolved CO, was measured with a nondispersive infrared analyzer (Van Hall et al, 1963). Organic carbon samples taken from Canadian rivers were generally grab type.…”

Transport of organic carbon in rivers of North America to the oceans was assessed by compiling and analyzing data from 82 North American rivers draining 60% of Canada and the United States. These data were collected by the U.S. Geological Survey and the Water Resources Branch of Canada's Inland Waters Directorate. Mean annual concentrations of total organic carbon showed considerably less variation than did annual specific export (gC m-2 yr-l).

Samples are analyzed on a Shimadzu TOC-Vcsh using the high-temperature catalytic oxidation method (HTCO) and measured on a non-dispersive infra-red (NDIR) detector.…”

Evaluating Cumulative Ecosystem Response to Restoration Projects in the Columbia River Estuary, 2004iii AbstractThe restoration of wetland salmon habitat in the 235-km tidal portion of the Columbia River is accelerating and is anticipated to improve habitat quality through hydrological reconnection of existing and restored habitats. Currently, multiple groups are implementing a variety of restoration strategies. However, the region lacks a standardized means of evaluating the effectiveness of individual projects and methods for assessing estuary-wide cumulative effects. This project is establishing a framework for such evaluations. A priority has been to develop a protocol manual for minimum monitoring of physical and biological metrics, intended to standardize data collection critical for analyzing changes following restoration actions. The draft manual included with this report is a practical technical guide for the design and implementation of restoration monitoring from Bonneville Dam to the river mouth. Additionally, the project's literature review and synthesis identified ways that effects can accumulate (e.g., cross-boundary effects, compounding effects) as well as analytical tools (e.g., models, matrices) for assessing them. Restoration project managers on the estuary began using the draft manual in 2005, and their feedback will be incorporated as the manual is finalized for wider distribution. Field studies are being implemented to test the protocols and to evaluate additional potential indicators for detecting a signal in the estuarine system (e.g., organic matter production, sedimentation, food webs, biodiversity, salmon habitat usage, and allometry.) Baseline data were collected in 2005 on two restoration sites and two associated reference sites. The sites represent two habitat types of the estuary -brackish marsh and freshwater swampthat have sustained substantial losses in area and that may play important roles for salmonids. Baseline data collected included vegetation and elevation surveys, above-and below-ground biomass, water depth and temperature, nutrient flux, fish species composition, and channel geometry. This data will be reported and evaluated in the 2005 Annual Report, which will include a new version of the protocol manual revised based on 2005 field work. Evaluating Cumulative Ecosystem Response to Restoration Projects in the Columbia River Estuary, 2004 iv Evaluating Cumulative Ecosystem Response to Restoration Projects in the Columbia River Estuary, 2004 v PrefaceThis report is a deliverable for the 2004 study. As such, it includes all of our work products for the 2004 study year. Future annual reports will be prepared for the remaining study years 2005 through 2009. In this report we introduce the research problem (Chapter 1), review the literature (Chapter 2), summarize CRE habitat use by juvenile salmon (Chapter 3), describe a conceptual model for the CRE ecosystem (Chapter 4), develop standard monitoring protocols for CRE restoration projects (Chapter 5), and provide recommendati...
