Growth Rate of Stony Corals of Broward County, Florida: Effects from Past Beach Renourishment Projects
The skeletal growth of hermatypic (reef-building) corals is a sensitive indicator of environmental conditions and perturbations. In particular, excessive sedimentation and turbidity act to depress coral growth because energy expenditure is required to remove sediment and because turbidity reduces light energy necessary for coral health and nutrition.
Normalized annual growth (linear skeletal extension) rates of Broward County, Florida reef-building corals were over 16 years (1985-1970). Star corals (Montastrea annularis) and brain corals (Diploria labyrinthiformis) were collected from each of four reef sites at two depths (9m and 18m). Collection areas were located in the vicinity of possible adverse sedimentation/turbidity effects from one or more of six past beach renourishment projects.
Coral growth differences among sites at particular years and among years within sites were statistically evaluated. Years tested included those of and subsequent to each of six past beach renourishment projects. The results are suggestive that, in general, Broward County beach renourishment projects have had minor or no influence on currently living off-shore corals.
However, following the Hollywood-Hallandale renourishment project of 1979, D. labyrinthiformis from the Hollywood 18m site exhibited significantly lower normalized growth compared to other sites. This may not represent effects from the renourishment project. At the Hollywood site M. annularis from both 9m and 18m and D. labyrinthiformis from 9m did not exhibit significantly lowered growth in comparison to other sites.
Site averages of absolute coral growth indicated that southern 9m specimens had higher rates of growth than northern counterparts for M. annularis. In the southern collection sites, 9m growth of both species tended to be greater than 18m growth.
Correlation analysis indicated that the time pattern of coral growth is similar among sites, species, and depths. Comparison of time series of coral growth data to recorded environmental variables (temperature and salinity) revealed a positive relation with salinity (water density) variations

Water Quality Control Plan. San Francisco Bay Basin (Region 2)
The State Water Resources Control Board and the nine Regional Water Quality Control Boards were created to solve California\u27s water quality problems. Operating under the provisions of the California Water Code. their unique relationship provides state level coordination and regional familiarity with local needs and conditions. Their joint actions constitute a comprehensive program for managing water quality in California. as well as effective State administration of the Federal water pollution control laws
Water Quality Control Plan. San Francisco Bay Basin (Region 2)
The San Francisco Bay estuarine system conveys the waters of the Sacramento and San Joaquin rivers into the Pacific Ocean. Located on the central coast of California (Figure 1-1 ), the Bay system functions as the only drainage outlet for waters of the Central Valley. It also marks a natural topographic separation between the northern and southern coastal mountain ranges. The region\u27s waterways, wetlands, and bays form the centerpiece of the United States\u27 fourth largest metropolitan region, including all or major portions of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma counties

Atmospheric benzene observations from oil and gas production in the Denver-Julesburg Basin in July and August 2014
High time resolution measurements of volatile organic compounds (VOCs) were collected using a proton-transfer-reaction quadrupole mass spectrometry (PTR-QMS) instrument at the Platteville Atmospheric Observatory (PAO) in Colorado to investigate how oil and natural gas (O&NG) development impacts air quality within the Wattenburg Gas Field (WGF) in the Denver-Julesburg Basin. The measurements were carried out in July and August 2014 as part of NASA’s “Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality” (DISCOVER-AQ) field campaign. The PTR-QMS data were supported by pressurized whole air canister samples and airborne vertical and horizontal surveys of VOCs. Unexpectedly high benzene mixing ratios were observed at PAO at ground level (mean benzene = 0.53 ppbv, maximum benzene = 29.3 ppbv), primarily at night (mean nighttime benzene = 0.73 ppbv). These high benzene levels were associated with southwesterly winds. The airborne measurements indicate that benzene originated from within the WGF, and typical source signatures detected in the canister samples implicate emissions from O&NG activities rather than urban vehicular emissions as primary benzene source. This conclusion is backed by a regional toluene-to-benzene ratio analysis which associated southerly flow with vehicular emissions from the Denver area. Weak benzene-to-CO correlations confirmed that traffic emissions were not responsible for the observed high benzene levels. Previous measurements at the Boulder Atmospheric Observatory (BAO) and our data obtained at PAO allow us to locate the source of benzene enhancements between the two atmospheric observatories. Fugitive emissions of benzene from O&NG operations in the Platteville area are discussed as the most likely causes of enhanced benzene levels at PAO
Adaptation of international guidelines on assessment and management of cancer pain for the Australian context
Aim: To develop clinical practice guidelines for screening, assessing and managing cancer pain in Australian adults.
Methods: This three phase project utilised the ADAPTE approach to adapt international cancer pain guidelines for the Australian setting. A Working Party was established to define scope, screen guidelines for adaptation, and develop recommendations to support better cancer pain control through screening, assessment, pharmacological and non-pharmacological management, and patient education. Recommendations with limited evidence were referred to Expert Panels for advice before the draft guidelines were opened for public consultation via the Cancer Council Australia Cancer Guidelines Wiki platform in late 2012. All comments were reviewed by the Working Party and the guidelines revised accordingly.
Results: Screening resulted in six international guidelines being included for adaptation - those developed by the Scottish Intercollegiate Guidelines Network (2008), National Health Service Quality Improvement Scotland (2009), National Comprehensive Cancer Network (2012), European Society of Medical Oncology (2011), European Association for Palliative Care (2011, 2012) and National Institute of Clinical Excellence (2012). Guideline adaptation resulted in 55 final recommendations. The guidelines were officially launched in November 2013.
Conclusion: International guidelines can be efficiently reconfigured for local contexts using the ADAPTE approach. Availability of the guidelines via the Cancer Council Australia Wiki is intended to promote uptake and enable recommendations to be kept up to date. Resources to support implementation will also be made available via the Wiki if found to be effective by a randomised controlled trial commencing in 2015
