“…By contrast, the superficial layer, where the depth varies between the sea surface and about −10 m, is characterized by the presence of surface water and intermediate water. The results discussed here are comparable with those described in [41], obtained from the analysis of the data recorded using the ArLoC sensor prototype developed by the research group from the University of Tuscia [38,42] and mounted onboard PROTEUS during the 2018 EXCELLABUST campaign in Svalbard.…”

This paper focuses on the development of new approaches to observe transient phenomena in critical marine environments using autonomous marine vehicles (AMVs) for the acquisition of physical and biogeochemical parameters of water and seabed characterization. The connection with metrological principles, together with the adoption of observing methodologies adjustable according to the specific marine environment being studied, allows researchers to obtain results that are reliable, reproducible, and comparable with those obtained through the classic monitoring methodologies. Tests were executed in dramatically dynamic, sensitive, and fragile areas, where the study and application of new methodologies is required to observe phenomena strongly localized in space and requiring very high resolutions, in time. Moreover, the harsh environmental conditions may present risks not only for the quality and quantity of the acquired data but also for the instrumentation and the operators. This is the case, for instance, in polar marine environments in proximity of tidal glaciers and in the Mediterranean Sea in areas characterized by seabed degassing activities, where AMV-supported monitoring procedures can allow for the safe observation of not repeatable and not completely predictable events.

“…The Global Ocean Observing System (GOOS) recommends sustained, routine and high-quality multi-disciplinary observations at a range of spatial and temporal scales that support scientific understanding, and management decisions about resource condition and sustainable use of our marine and coastal systems (Palacz et al, 2017). Whilst physical and chemical data collection and distribution has benefitted enormously from advances in technology (Marcelli et al, 2012), and international collaborative program (Hood, 2009;Palacz et al, 2017), biological datasets with sufficient taxonomic resolution to detect change are still relatively sparse, especially in the Southern Hemisphere. Australia in particular has had few sustained (>10 years) biological monitoring program (Lynch et al, 2014), which capture the wide range of ecosystems present (tropical, subtropical, temperate, sub-Antarctic) and the influence of the different water masses on species diversity and abundance.…”

Australia’s Long-Term Plankton Observations: The Integrated Marine Observing System National Reference Station Network

et al. 2019

View full text Add to dashboard Cite

The Integrated Marine Observing System National Reference Station network provides unprecedented open access to species-level phytoplankton and zooplankton data for researchers, managers and policy makers interested in resource condition, and detecting and understanding the magnitude and time-scales of change in our marine environment. We describe how to access spatial and temporal plankton data collected from the seven reference stations located around the Australian coastline, and a summary of the associated physical and chemical parameters measured that help in the interpretation of plankton data. Details on the rationale for site locations, sampling methodologies and laboratory analysis protocols are provided to assist with use of the data, and design of complimentary investigations. Information on taxonomic entities reported in the plankton database, and changes in taxonomic nomenclature and other issues that may affect data interpretation, are included. Data from more than 1250 plankton samples are freely available via the Australian Ocean Data Network portal and we encourage uptake and use of this continental-scale dataset, giving summaries of data currently available and some practical applications. The full methods manual that includes sampling and analysis protocols for the Integrated Marine Observing System Biogeochemical Operations can be found on-line.

“…The use of these alternative technologies also enables researchers to provide sea-truth data for satellite observations, which are fundamental to study the marine environment at high spatial and temporal resolution but requires observational data for calibration and validation [ 18 ]. Continuous advances in sensor technology and materials make it possible to develop new probes with suitable characteristics for different oceanographic applications, providing new opportunities for global ocean observation and monitoring [ 19 ].…”

The Arctic region is known to be severely affected by climate change, with evident alterations in both physical and biological processes. Monitoring the Arctic Ocean ecosystem is key to understanding the impact of natural and human-induced change on the environment. Large data sets are required to monitor the Arctic marine ecosystem and validate high-resolution satellite observations (e.g., Sentinel), which are necessary to feed climatic and biogeochemical forecasting models. However, the Global Observing System needs to complete its geographic coverage, particularly for the harsh, extreme environment of the Arctic Region. In this scenario, autonomous systems are proving to be valuable tools for increasing the resolution of existing data. To this end, a low-cost, miniaturized and flexible probe, ArLoC (Arctic Low-Cost probe), was designed, built and installed on an innovative unmanned marine vehicle, the PROTEUS (Portable RObotic TEchnology for Unmanned Surveys), during a preliminary scientific campaign in the Svalbard Archipelago within the UVASS project. This study outlines the instrumentation used and its design features, its preliminary integration on PROTEUS and its test results.
