A buoy is a structure that is float on the sea surface used for the navigational, marine science, monitoring the meteorology and oceanography changes of the marine environment. This article presents a literature review on research and development of floating buoy technology for research purposes. The article starts with the historical background of various buoy technologies. Then, floating buoy working principles used for research are discussed. The reviewed according to the type of buoy technology for research purposes (tsunami buoy type, wave buoy type, weather buoy type, and profiling buoy type). This is followed by an overview of the buoy applications that have been undertaken by Malaysian research communities. The proposed concept design of buoy will be shown with the initial stability parameters analysis. To conclude, based on the research work undertaken thus far, what the researchers should expect as future work are suggested.

“…Conversely, tsunami buoys can be stationed in the deep sea and are able to provide adequate warning time with heavy upfront and maintenance costs. The existing tsunami buoys in the Indian Ocean are meant to serve the host country as the first priority and are geographically deployed likewise (Aasen et al 2007). The suggestion for Sri Lanka to deploy its own buoys increases the chance of saving hundreds of threatened local communities while providing added reliability to the entire buoy system in the Indian Ocean.…”

The massive devastation of the Indian Ocean mega tsunami in 2004, clearly calls for an efficient early warning system for the Indian Ocean countries. The 'Regional Watch Provider' system currently planned makes some countries entirely dependent on the watch providers. We discuss a feasible and reliable tsunami detection mechanism for Sri Lanka that would give it some independent information for decision making purposes. It contemplates Sri Lanka deploying its own additional detection tools. A stand-alone tide gauge system, a buoy system and a combined gauge and buoy system are tested with the status quo or 'do nothing' alternative. A decision analysis exercise investigates the probability of tsunamis, probability of failures of each detection system, the probability of successful completion of an evacuation and the probability of false warnings which have their own costs. This paper concludes with the derived recommendations for a preferred tsunami detection system for Sri Lanka.

“…Quantitative polymerase chain reaction (qPCR) assay is recognized as one of the most sensitive quantitation method for detecting microalgae in seawater, and has been applied in harmful algal bloom (HAB) studies (Popels et al 2003;Casper et al 2004;Galluzzi et al 2004;Hosoi-Tanabe and Sako 2005;Zhang and Lin 2005;He et al 2007;Zhao et al 2009;Ulrich et al 2010). So far two qPCR methods targeting the 18S rDNA sequence have been developed to detect A. anophagefferens (Popels et al 2003;Wang and Lei 2016).…”

Brown tides of pelagophyte Aureococcus anophagefferens have been recorded in the coastal waters of Qinhuangdao in the Bohai Sea (BS) since 2009. Current understandings on the dynamics and mechanisms of brown tides in the BS, however, are still quite limited due to the lack of accurate methods for detecting low‐abundance of A. anophagefferens cells. In this study, a Taqman qPCR method was developed, which targeted 28S rDNA D1‐D2 domain of A. anophagefferens. The specificity of the qPCR method was tested using 25 strains of microalgae commonly present in the coastal waters, and the targeted species A. anophagefferens was the only species that had reliable positive signal. The method was highly sensitive and reproducible, and the lower detection limit could reach 0.3 cells of A. anophagefferens. A calibration curve was established for A. anophagefferens using the DNA template extracted from different number of cells, and the lower and upper limits of detection for the qPCR assay is 0.3 cells and 1.2 × 105 cells, respectively. A high recovery rate ranged from 96.5% to 107% was achieved for A. anophagefferens at different cell densities. The qPCR assay has been successfully applied to the study on spatial and temporal variations of A. anophagefferens in the coastal waters of Qinhuangdao in 2014.
