An integrated suspended sediment transport monitoring and analysis concept

A new integrated suspended sediment monitoring strategy applying direct and indirect technologies is presented.Optical sensors continuously record the turbidity at one point in the channel cross section close to the river bank and are calibrated by water samples taken close to the sensor.Additionally measurements are performed to establish the distribution of suspended sediment in a cross section（bottle samples combined with acoustic devices）.Using correction factors（probe and cross-sectional factor） these monitoring methods are combined and it is,thus,possible to fully document the temporal and spatial variability of the suspended sediment transport and to estimate the suspended sediment load for certain time periods.This monitoring strategy was implemented at various measurement sites in Austria as well as at the Hainburg Road Bridge site on the Danube River.It has already been successfully applied for three years at this measurement site and suspended sediment loads during high discharges up to a 15 year flood event have been monitored.To evaluate the new monitoring methods the results were compared with load estimation methods found in the literature including averaging and ratio estimators as well as rating curves.The results prove that with the new methodology,the temporal variability of the suspended sediment transport can be detected more accurately compared with the other methods.They also demonstrate that the additional consideration of the spatial distribution of the suspended sediment concentration in the cross section is crucial as the mean concentration in the cross section can significantly exceed the concentration near the banks,especially at large rivers like the Danube River.     

From ad hoc towards the institutionalisation: An assessment of Malaysia's policy evolution on Antarctica and the Southern Ocean

Malaysia's policy on Antarctica and the Southern Ocean (A&SO) in the last three decades has evolved from being focused on diplomatic engagement to pioneering science in cooperation with the international community and strengthening science diplomacy by becoming a member of the international governance of Antarctic. Through process-oriented evaluation, the aim of this study is to map out the development of Malaysia's policy on the Antarctic region (from 1982 to 2016) and consequently, identify the current capacities and future needs to strengthen its involvement. This study reveals that Malaysia's policy on A&SO has strong integration in foreign affairs, science and technology (S&T), and the environment, and the involvements are parallel with the national development plan. To move forward, Malaysia is currently establishing a suitable governance structure and a long-term management plan to ensure a long-term political commitment, sustain investment of resources and strengthen the dynamic participation of stakeholders. This study advances the scholarly understanding of the political processes and challenges to Malaysia's Antarctic policy development, in its journey towards institutionalisation which will create distinctive and valuable positions for Malaysia to contribute to current debates on the future of the Antarctic region. In the context of ad-hoc decision on certain policy, this case study will contribute relevant information about the development process, issues and challenges on policy through ad-hoc implementation.     

Factors affecting recapture rates of raggedtooth sharks Carcharias taurus tagged off the east coast of South Africa

Understanding differences in the recapture rate between different tags (A-, B- and C-types), capture methods (rock-and-surf anglers, scientific divers and Natal Sharks Board protection nets) and life-history stages (juvenile and adult) is critical in evaluating the results obtained from cooperative tagging programmes (CTPs). A generalised linear modelling approach, using a log-linear model, was used to determine significant differences in the probability of recapture between these various factors using data from the Oceanographic Research Institute and Port Elizabeth Museum CTPs. Between 1984 and 2004, a total of 3 385 raggedtooth sharks Carcharias taurus was tagged by volunteers from both programmes along the east coast of South Africa. A likelihood ratio test indicated significant differences in the probability of recapture between A- and C-type and B- and C-type tags (p < 0.01), between different capture methods (p < 0.05) and between juvenile and adult sharks (p < 0.01). A comparison of recapture rates between members of the CTPs also indicated a marked variability in the performance of individual taggers. The study highlights important data-quality issues inherent in large CTPs.

Use of the ACDEP trajectory model in the Danish nation-wide Background Monitoring Programme

The frequently observed eutrophication problems in Danish marine waters are associated with high nutrient loads. This paper outlines how the atmospheric part of the load is determined within the framework of the Danish Background Monitoring Programme. The analyses within the programme are carried out by use of both measurements and model calculations, where the modelling part receives the main focus in this paper. The performed calculations indicate that the atmospheric nitrogen deposition to the Danish marine waters is of comparable size to the river run-off, and in some periods even the dominating contribution to the overall nitrogen input. The model results are shown to be sensitive to the resolution of the meteorological input data for the calculations. Strong improvement of the model performance is the result when meteorological data with much higher temporal and spatial resolution are applied.
