Results from local measurements of aerosol and black carbon concentrations in marine expeditions are burdened by technogenic impacts onboard research vessel and failures of instruments due to unfavorable operation conditions. In this report, we present an algorithm of automatic datafiltering, ensuring the preparation of observation time series for a subsequent physical analysis. In addition, we discuss an artifact of recording negative black carbon concentrations, caused by insufficient aethalometer sensitivity in the region of the lowest concentrations. It is noted that, to overcome this problem, data should be averaged over a longer period of time, without disregarding negative concentrations.

The massive web-based information resources have led to an increasing demand for effective automatic retrieval of target information for web applications. This paper introduces a web-based data extraction tool that deploys various algorithms to locate, extract and filter tabular data from HTML pages and to transform them into new web-based representations. The tool has been applied in an aquaculture web application platform for extracting and generating aquatic product market information. Results prove that this tool is very effective in extracting the required data from web pages.
