Relationship between chlorophyll specific productivity and temperature at the surface in Sagami Bay, Japan

Primary production was monthly measured from September 2001 to July 2003 at the surface in Sagami Bay, Japan. Thevariation in the primary production was primarily due to the variation in Pb (chlorophyll specific productivity). The values ofPb positively correlated with temperature. This may be due to relatively low contribution of diatoms in Sagami Bay

Vacuous standards – Subversion of the OSAC standards-development process

In the context of development of standards for forensic science, particularly standards initially developed by the U.S. Organization of Scientific Area Committees for Forensic Science (OSAC), this perspective paper raises concern about the publication of vacuous standards. Vacuous standards generally state few requirements; the requirements they do state are often vague; compliance with their stated requirements can be achieved with little effort – the bar is set very low; and compliance with their stated requirements would not be sufficient to lead to scientifically valid results. This perspective paper proposes a number of requirements that we believe would be essential in order for a standard on validation of forensic-science methods to be fit for purpose

Shifting landscapes: from coalface to quick sand? Teaching geography, earth and environmental sciences in UK higher education

In this paper we examine contemporary academic working lives, with particular reference to teaching-only and teaching-focused academics. We argue that intensification in the neoliberal university has significantly shifted the structure of academic careers, while cultural stories about those careers have not changed. We call for academics to re-examine our collective stories about standard academic career paths. Challenging the stories and making visible the ways that they create and multiply disadvantage is a crucial step in expanding the possibilities for academic identities and careers. The paper begins by describing teaching-focused academics within the context of the wider workforce. We then draw on narratives of those in these roles to illustrate the processes that (re)inscribe their marginalisation. We uncover the gendering of the teaching-focused academic labour market. We end the paper by suggesting interventions that all academics can take and support to address the issues we highlight

Reliable, resilient and sustainable urban drainage systems: an analysis of robustness under deep uncertainty (article)

This is the author accepted manuscript. The final version is available from the American Chemical Society via the DOI in this record.The dataset associated with this article is available in ORE at: https://doi.org/10.24378/exe.563Reliability, resilience and sustainability are key goals of any urban drainage system. However, only a few studies have recently focused on measuring, operationalizing and comparing such concepts in a world of deep uncertainty. In this study, these key concepts are defined and quantified for a number of gray, green and hybrid strategies, aimed at improving the capacity issues of an existing integrated urban wastewater system. These interventions are investigated by means of a regret-based approach, which evaluates the robustness (that is the ability to perform well under deep uncertainty conditions) of each strategy in terms of the three qualities through integration of multiple objectives (i.e. sewer flooding, river water quality, combined sewer overflows, river flooding, greenhouse gas emissions, cost and acceptability) across four different future scenarios. The results indicate that strategies found to be robust in terms of sustainability were typically also robust for resilience and reliability across future scenarios. However, strategies found to be robust in terms of their resilience and, in particular, for reliability did not guarantee robustness for sustainability. Conventional gray infrastructure strategies were found to lack robustness in terms of sustainability due to their unbalanced economic, environmental and social performance. Such limitations were overcome, however, by implementing hybrid solutions that combine green retrofits and gray rehabilitation solutions.This study was funded by the UK Engineering and Physical Sciences Research Council through STREAM (EP/G037094/1) with Northumbrian Water Limited, BRIM (EP/N010329/1) and the final author’s fellowship Safe & SuRe (EP/K006924/1)

Sea Level Rise Adaptation Plan for Transportation Infrastructure and Other Critical Resources in the Eureka Slough Hydrographic Area, Humboldt Bay

This plan (study) presents a framework for developing sea level rise adaptation strategies within the highly vulnerable Eureka Slough hydrographic area of Humboldt Bay. The purpose of the study was to work with public agencies, landowners, scientists, and stakeholders to better understand the specific flood risks to the transportation infrastructure and other critical resources within the study area and to identify viable adaptation measures in the near-term planning horizon (now through mid-century) for the most at-risk locations. A primary focus of the study was to develop a scenario-based planning approach for understanding the range of possible impacts and consequences resulting from tidal and fluvial flood hazards under current conditions and with future sea level rise. This approach included detailed hydraulic analysis and an evaluation of the anticipated response of the coastal landscape to various flooding events. The plan is intended to help advance the collective understanding of flood risks and improve the readiness for implementing effective sea level rise adaptation projects. This plan is a technical resource for ongoing planning and adaptation efforts but is not a decision document and does not represent a commitment to implement the project concepts discussed in the plan

Impact of the assimilation of ozone from the Tropospheric Emission Spectrometer on surface ozone across North America

We examine the impact of assimilating ozone observations from the Tropospheric Emission Spectrometer (TES) on North American surface ozone abundances in the GEOS-Chem model in August 2006. The assimilation reduces the negative bias in the modeled free tropospheric ozone, which enhances the ozone flux into the boundary layer. Surface ozone abundances increased by as much as 9 ppb in western North America and by less than 2 ppb in the southeast, resulting in a total background source of ozone of 20-40 ppb. The enhanced ozone in the model reduced the model bias with respect to surface ozone observations in the western USA, but exacerbated it in the east. This increase in the bias in the boundary layer in the east, despite the agreement between the assimilation and ozonesonde measurements in the free troposphere, suggests errors in the ozone sources or sinks or in boundary layer mixing in the model. © 2009

Strategic risk appraisal. Comparing expert- and literature-informed consequence assessments for environmental policy risks receiving national attention

Strategic risk appraisal (SRA) has been applied to compare diverse policy level risks to and from the environment in England and Wales. Its application has relied on expert-informed assessments of the potential consequences from residual risks that attract policy attention at the national scale. Here we compare consequence assessments, across environmental, economic and social impact categories that draw on ‘expert’- and ‘literature-based’ analyses of the evidence for 12 public risks appraised by Government. For environmental consequences there is reasonable agreement between the two sources of assessment, with expert-informed assessments providing a narrower dispersion of impact severity and with median values similar in scale to those produced by an analysis of the literature. The situation is more complex for economic consequences, with a greater spread in the median values, less consistency between the two assessment types and a shift toward higher severity values across the risk portfolio. For social consequences, the spread of severity values is greater still, with no consistent trend between the severities of impact expressed by the two types of assessment. For the latter, the findings suggest the need for a fuller representation of socioeconomic expertise in SRA and the workshops that inform SRA output

The views of five participating undergraduate students of the Student Associates Scheme in England

This paper reports findings from a study which explored undergraduate perceptions of the Student Associates Scheme in England (SAS). The scheme was established by the Training and Development Agency for Schools in an attempt to increase the number of graduates entering the teaching profession, particularly in shortage subjects such as the physical sciences and mathematics. The scheme places undergraduate students on short-term placements in secondary schools throughout England to provide them with experiences that may encourage them to consider teaching as a career option. Findings show that the SAS school placements were a positive experience for the students participating in this study. However, a question emerged as to whether or not the scheme is targeting students who have yet to decide upon teaching as a career or just reinforcing the existing aspirations of students who have already decided to teach. As the scheme is attempting to increase the number of teachers entering the profession this question has important implications for this study and further work which will focus on undergraduates who think that their career ambitions would not be fulfilled by teaching
