Biophysical assessment of reefs in Keppel Bay: a baseline study (April 2007)
The Keppel Islands are a group of 16 continental islands lying 18 km off the coastal town of Yeppoon in the southern Great Barrier Reef. Located in the shallow basin to the north of Keppel Bay, the islands are host to a patchwork of fringing reefs in various forms of development. Coral communities are abundant in some locations, and coral cover is high (60 to 70%) relative to the average at sites surveyed by the Australian Institute of Marine Scienceâs Long-Term Monitoring Program (~35%), and are often dominated by extensive stands of branching Acropora that extend into shallow water. These âstaghornâ corals are vulnerable to impacts caused by environmental stresses such as elevated sea temperature (causing coral bleaching events), degraded water quality (associated with hyposaline floods events) and physical damage (from cyclones, storms and anchoring). The Fitzroy River, one of the largest catchments in Queensland, is about 40 km to the south of the Keppel Islands. Large flood plumes occur approximately every 10 years, and the soft riverine sediments are regularly re-suspended in the shallow bay by wind and tide action causing high turbidity. Heavy rainfall also affects the shallow reef flat habitats, with reported incidences of coral mortality caused by heavy rain at times of extreme low tidesID: 176
Weekly water quality monitoring data for the River Thames (UK) and its major tributaries (2009â2013): the Thames Initiative research platform
The River Thames and 15 of its major tributaries have been monitored at weekly intervals since March 2009. Monitored determinands include major nutrient fractions, anions, cations, metals, pH, alkalinity,
and chlorophyll a and are linked to mean daily river flows at each site. This catchment-wide biogeochemical
monitoring platform captures changes in the water quality of the Thames basin during a period of rapid change, related to increasing pressures (due to a rapidly growing human population, increasing water demand and climate change) and improvements in sewage treatment processes and agricultural practices. The platform provides the research community with a valuable data and modelling resource for furthering our understanding of pollution sources and dynamics, as well as interactions between water quality and aquatic ecology. Combining Thames Initiative data with previous (non-continuous) monitoring data sets from many common study sites, dating back to 1997, has shown that there have been major reductions in phosphorus concentrations at most sites, occurring at low river flow, and these are principally due to reduced loadings from sewage treatment works (STWs). This ongoing monitoring programme will provide the vital underpinning environmental data required to best manage
this vital drinking water resource, which is key for the sustainability of the city of London and the wider UK economy.

Knowledge Management in Practice: The Case of International Development
Knowledge management as an organizational discipline, while originally developed in a business environment, has seen keen pursuit in disciplines contributing to more sustainable forms of social organization. In less than ten years, knowledge management for development - or KM4D as it is widely known - has become a prominent strategy in many organizations around the world working toward international development. This chapter illustrates the strategic evolution of KM4D drawing on a case study of a development community of practice, following a three-phase model, focusing on technology, on organizational processes and on people. It addresses the meaning of power in knowledge management (for development) and identifies challenges and possible future research directions for the field
Hubble, trouble, toil and space rubble: The management history of an object in space
This article tells the saga of the Hubble Space Telescope, and how the attempt to overcome the restrictions Earths atmosphere imposes upon astronomy, came to dominate the existence of NASA in the later part of the 20th century.This biography of an object is told over four stages fundamental to the order of management; development, failure, recovery and completion.With a failed mirror, what became hidden and forgotten, was once more revealed.With the wild and uncertain dimension of Hubbleâs assemblage disclosing itself through malfunction, management was able to rescue through repair its prior unavailability. Eventually management has contended with Hubbleâs demise as it fades out of view during the process of completion. Running in counterpart to the four stages of Hubbleâs life will be an explication of the events using the work of Martin Heidegger, particularly his work and concepts of Being and Time (Heidegger, 1962)
