City of Concord Complete Streets Study

The purpose of this report is to summarize the data collected as a part of the Concord Complete Streets Study and to provide the City with preliminary support in the progress to construct a safer, more bike and pedestrian friendly Concord. The developments and visions found in this document provide a platform for continued discussion on creating a more pedestrian and bicycle friendly environment that encourages other forms of transportation and provides alternatives to dependency on automobiles

City of San Luis Obispo, Open Space Survey

The City of San Luis Obispo (SLO) has eleven official public open spaces. Managing these places presents a challenge in providing top-tier environmental stewardship, while also accommodating passive recreational use and access, in an era of fiscal limitations and competing priorities. Given that reality and the changing population dynamics in the US, providing equal access to these facilities is of increasing importance, whether by car, bike, on foot or via public transit. These open spaces provide value (environmental, economic and social) primarily to residents, as well as visitors, and gaining a data-driven understanding of that value was a primary goal of this study. Within this framework, team of undergraduate and graduate students from CalPoly, San Luis Obispo worked under the direction of Dr. William Riggs and Natural Resources Manager Robert Hill, to evaluate the conditions, characteristics-of, and visitors-to SLO open spaces. To accomplish this, the project team conducted an initial facilities assessment of the existing conditions at the entrances to SLO’s open spaces. Following this, a survey was conducted to gather information about use, conditions and travel / access to local open spaces. This was complimented by use data gathered from electronic counters placed at open space entrances

Tree-Ring Stable Isotope Measurements: The Role of Quality Assurance and Quality Control to Ensure High Quality Data

Quality assurance and quality control (QA/QC) are important components of every study. In this chapter, we give an overview of QA/QC specific for tree-ring stable-isotope analysis from the perspective of the entire research project, rather than from the operation of Isotope Ratio Mass Spectrometers (IRMS). We address how users of stable isotope tree-ring data can quantify the quality of their data for reporting in publications by calculating accuracy and precision. We cover some of the potential sources of error that can occur during sample processing and isotopic measurements, basic principles of calibration to the appropriate isotopic scales, and how researchers can detect error and calculate uncertainty using duplicates and quality control standards.ISSN:0829-318XISSN:1758-446

Using nocturnal cold air drainage flow to monitor ecosystem processes in complex terrain

This paper presents initial investigations of a new approach to monitor ecosystem processes in complex terrain on large scales. Metabolic processes in mountainous ecosystems are poorly represented in current ecosystem monitoring campaigns because the methods used for monitoring metabolism at the ecosystem scale (e.g., eddy covariance) require flat study sites. Our goal was to investigate the potential for using nocturnal down-valley winds (cold air drainage) for monitoring ecosystem processes in mountainous terrain from two perspectives: measurements of the isotopic composition of ecosystem-respired CO2 (δ13CER) and estimates of fluxes of CO2 transported in the drainage flow. To test if this approach is plausible, we monitored the wind patterns, CO2 concentrations, and the carbon isotopic composition of the air as it exited the base of a young (∼40 yr-old) and an old (\u3e 450 yr-old) steeply sided Douglas-fir watershed. Nocturnal cold air drainage within these watersheds was strong, deep, and occurred on more than 80% of summer nights. The depth of cold air drainage rapidly increased to tower height or greater when the net radiation at the top of the tower approached zero. The carbon isotope composition of CO2 in the drainage system holds promise as an indicator of variation in basin-scale physiological processes. Although there was little vertical variation in CO2 concentration at any point in time, we found that the range of CO2 concentration over a single evening was sufficient to estimate δ13CER from Keeling plot analyses. The seasonal variation in δ13CER followed expected trends: during the summer dry season δ13CER became less negative (more enriched in 13C), but once rain returned in the fall, δ13CER decreased. However, we found no correlation between recent weather (e.g., vapor pressure deficit) and δ 13CER either concurrently or with up to a one-week lag. Preliminary estimates suggest that the nocturnal CO2 flux advecting past the 28-m tower is a rather small fraction ( \u3c 20%) of the watershed-scale respiration. This study demonstrates that monitoring the isotopic composition and CO2 concentration of cold air drainage at the base of a watershed provides a new tool for quantifying ecosystem metabolism in mountainous ecosystems on the basin scale. © 2007 by the Ecological Society of America
