A standard processing framework for the location data of satellite-linked buoys on drifting fish aggregating devices
Satellite-linked buoys used by tropical tuna purse-seine vessels on drifting fish aggregating devices (DFADs) provide a continuous stream of information on both the ocean characteristics and the presence and size of fish aggregations associated with DFADs, enabling the study of pelagic communities. This unprecedented amount of data is characterized by ocean-scale coverage with high spatial and temporal resolutions, but also by different data formats and specifications depending on buoy model and brand, as well as on the type of data exchange agreements into play. Their use for scientific and management purposes is therefore critically dependent on the abilities of algorithms to process heterogeneous data formats and resolutions. This paper proposes a unified set of algorithms for processing the buoys location data used by the two major purse seine fleets operating in the Atlantic and Indian oceans. Three main issues that need to be addressed prior to the exploitation of the data are identified (structural errors, data records on land and on-board vessels) and five specific filtering criteria are proposed to improve the data cleaning process and, hence, quality. Different filtering procedures are also compared, and their advantages and limitations are discussed.
期刊介绍:
Aquatic Living Resources publishes original research papers, review articles and propective notes dealing with all exploited (i.e. fished or farmed) living resources in marine, brackish and freshwater environments.
Priority is given to ecosystem-based approaches to the study of fishery and aquaculture social-ecological systems, including biological, ecological, economic and social dimensions.
Research on the development of interdisciplinary methods and tools which can usefully support the design, implementation and evaluation of alternative management strategies for fisheries and/or aquaculture systems at different scales is particularly welcome by the journal. This includes the exploration of scenarios and strategies for the conservation of aquatic biodiversity and research relating to the development of integrated assessment approaches aimed at ensuring sustainable and high quality uses of aquatic living resources.
