1.The recent development of miniaturized saltwater immersion geolocators has made it possible to track andrecord activity of even the smallest seabird species over extended periods of time.2.The resulting activity data comprise of various time stamps and immersion times integrated over 10-min inter-vals. Generally, such data sets are large and complex which makes analysis a daunting task, especially in theabsence of dedicated software solutions.3.We developed Actave.net as a freely accessible, web-based (http://www.actave.net) analysis tool for complexactivity data that provides cloud-based and automatic computation of daily aggregates of various activityparameters based on recorded immersion data. The tool furthermore calculates various astronomical parameters(e.g. moon illumination) based on locational information derived from geolocation.4.Actave.net provides maps and graphs for data exploration, download of processed data for modelling andstatistical analysis, and tools for sharing results with other users (e.g. collaborators). Currently, the tool supportsthe most frequently used M-Series immersion loggers (BAS/Biotrack Ltd), but support for a broader range ofdevicetypesaswellasexpandedanalysisfunctionalityisplannedforfuturereleases.
