Monitoring Algal Blooms with Complementary Sensors on Multiple Spatial and Temporal Scales

Climate change, and other human-induced impacts, are severely increasing the intensity and occurrences of algal blooms in coastal regions (IPCC, 2022). Ocean warming, marine heatwaves, and eutrophication promote suitable conditions for rapid phytoplankton growth and biomass accumulation. An increase in such primary producers provides food for marine organisms, and phytoplankton play an important global role in fixing atmospheric carbon dioxide and producing much of the oxygen we breathe. But harmful algal blooms (HABs) can also form, and they may adversely affect the ecosystem by reducing oxygen availability in the water, releasing toxic substances, clogging fish gills, and diminishing biodiversity. Understanding, forecasting, and ultimately mitigating HAB events could reduce their impact on wild fish populations, help aquaculture producers avoid losses, and facilitate a healthy ocean. Phytoplankton respond rapidly to changes in the environment, and measuring the distribution of a bloom and its species composition and abundance is essential for determining its ecological impact and potential for harm. Satellite remote sensing of chlorophyll concentration has been used extensively to observe the development of algal blooms. Although this tool has wide spatial and temporal (nearly daily) coverage, it is limited to surface ocean waters and cloud-free days. Microscopic analyses of water and net samples allow much closer examination of the species present in a bloom and their abundance, but this is a time-consuming process that collects only discrete point samples, sparsely distributed in space and time. Neither of these methods alone captures the rapid evolution of algal blooms, the spatial and temporal patchiness of their distributions, or their high local variability. In situ optical devices and imaging sensors mounted on mobile platforms such as autonomous underwater vehicles (AUVs) and uncrewed surface vehicles (USVs) capture fine-scale temporal trends in plankton communities, while uncrewed aerial vehicles (UAVs) complement satellite remote sensing. Use of such autonomous platforms offers the flexibility to react to local conditions with adaptive sampling techniques in order to examine the marine environments in real time. Here we present an integrated approach to observing blooms—an “observational pyramid”—that includes both classical and newer, complementary observation methods (Figure 1). We aim to identify trends in phytoplankton blooms in a region with strong aquaculture activity on the Atlantic coast of mid-Norway. Field campaigns were carried out in consecutive springs (2021 and 2022) in Frohavet, an area of sea sheltered by the Froan archipelago (Figure 2). The region is a shallow, highly productive basin with abundant fishing and a growing aquaculture industry. Typically, there are one or more large algal blooms here during the spring months. We use multi-instrumentation from macro- to a microscale perspectives, combined with oceanographic modeling and ground truthing, to provide tools for early algal bloom detection

Design and experimental validation of a control architecture for a wave-propelled USV: From system design to ocean studies

In a time of unprecedented anthropogenic pressures on the oceans, preserving the health of underwater ecosystems is of the uttermost importance. Since the beginning of human exploration of the oceans, ship-based ocean monitoring methodologies have dominated the stage, providing the ability to gather isolated point measurements mostly biased by poor scalability and continuity in space and time. The advent of robotic platforms has revolutionized ocean observation practices, enabling measurements on scales logistically and technologically impossible using traditional techniques. Wave-propelled unmanned surface vehicles (USVs) constitute a very unique class of marine robots that, unlike common platforms, are not constrained by onboard energy limitations since their propulsion is entirely due to waves. This makes them capable of performing long-duration operations and, therefore, of observing oceanographic phenomena at more appropriate spatio-temporal scales. The glaring advantages that, from a scientific point of view, come along with this class of USVs are however hindered by numerous navigation and control challenges. As their propulsion and heading rely on the environment, stable course-over-ground (COG) control can be a challenging task when environmental forces and forward propulsion are in the same order of magnitude. Moreover, navigation performances are likely to deteriorate when hostile sea conditions arise, to a point in which maneuverability is reduced and, eventually, controlling the vehicle is no longer possible. The principal contribution of this thesis relates to the design of a navigation control system that robustly governs the course of the commercially available, wavepropelled vehicle AutoNaut, when the environment generates drift forces acting on its body. In particular, the control design relies on extensive analysis of the nonlinearities appearing in the USV’s steering dynamics model, mainly caused by the low speed relative to water and to ground observed when environmental drift forces and the force due to wave propulsion are in the same order of magnitude. Additional contributions of this work are related to i) the design, implementation and experimental validation of the hardware and software onboard architectures, and ii) showcasing two applications in which the proposed system is employed in ocean studies

Design and Validation of a Course Control System for a Wave-Propelled Unmanned Surface Vehicle

Unlike common marine vessels, wave-propelled vehicles cannot directly control their speed, but rely instead on the forces exerted by the environment to navigate as intended. The unique navigation capabilities of such vehicles motivate the study of control solutions that adapt the vehicle heading to the prevailing environmental conditions and ensure robust course-keeping performances across different sea states, winds, and currents over extended periods of time. This article presents the design and experimental validation of a path following and course control system for an underactuated, wave-propelled unmanned surface vehicle (USV). The major focus and novelty of this work stands in the analysis of the model nonlinearities that appear when the vehicle propulsion force does not prevail on the wind and sea current forces generated by the environment. In these situations, low maneuverability is experienced depending on the magnitude of counteracting forces and, in some cases, loss of controllability is a risk. Initial investigation of the vehicle’s nonlinear dynamics is followed by derivation of a simplified quasilinear mathematical model that isolates the major source of nonlinearity. This provides a basis for the control design, the theory of which is supported and validated by extensive field experiments. In particular, when the USV’s ground speed is close to zero, the theory shows singularities in the model that lead to instabilities and loss of controllability of the course over ground that is experienced in the field. Our test results verify that an effective solution is to switch to heading control when the ground speed is small

Evaluation of school-based interventions including homework to promote healthy lifestyles: a systematic review with meta-analysis

Aim It is important to promote healthy lifestyles in youth through initiatives in school, which is a preferred setting to implement health-related interventions also targeted at families to be more effective. This study aimed to synthesise school-based interventions including homework and extracurricular activities for the promotion of healthy lifestyles, especially healthy nutrition and physical activity, in children and adolescents.Methods This systematic review was conducted according to the PRISMA guidelines. Quality assessment was performed using the Cochrane Tool for Quality Assessment for randomized and non-randomized control trials, while the STROBE (Strengthening the Reporting of Observational studies in Epidemiology) guidelines were used for observational studies.Results From the 1356 studies identified, eight were included. Across studies, a significant effect was found in increasing fruit and vegetable consumption and reducing snack and sugar intake, while no effect was found for moderate to vigorous physical activity (MVPA) unless for light PA (LPA) and step counts. The results of BMI and waist circumference are still unclear after performing a meta-analysis of three studies.Conclusion School-based interventions including homework and extracurricular activities were shown to improve nutritional behaviour, step counts, and LPA. Despite some statistically significant results, the effects of BMI and waist circumference are still unclear. Further studies are needed to demonstrate that these intervention s can represent an effective strategy for obesity prevention

A Satellite-USV System for Persistent Observation of Mesoscale Oceanographic Phenomena

Traditional tools and methodologies for mesoscale observation of oceanographic phenomena are limited by under-sampling and data latency. In this article we evaluate three different scenario variants of an architecture for how heterogeneous sensor nodes can be integrated with satellite remote sensing. Independent space and marine sensing platforms are interconnected either directly or by means of a ground-based mission control center responsible for data processing, relay, and coordination of the assets. A wave-propelled unmanned surface vehicle (USV) persistently collects in situ data of the targeted phenomenon. In two variants of the architecture, a dedicated small satellite acts as a sensor node, a data processing facility and a communication node. We have used a System-of-Systems (SoS) modeling approach coupled with operational simulations in different locations on Earth, in order to support the proposed methodology and investigate quantitatively the reduction the data latency to end-users. Through a combination of field experiments and simulations we estimate how the different scenarios perform with respect to providing remote sensing data that are used to create a measurement and navigation plan for the autonomous vessel
