Abstract

The Vendée Globe is the world’s most famous solo, non-stop, unassisted sailing race. The Institute of Marine Sciences and the Barcelona Ocean Sailing Foundation installed a MicroCAT on the One Ocean One Planet boat. The skipper, Dídac Costa, completed the round trip in 97 days, from 8 November 2020 to 13 February 2021, providing one measurement of temperature and conductivity every 30 s during navigation. More than half of the ship’s route was in the sub-Antarctic zone, between the tropical and polar fronts, and it passed through areas of oceanographic interest such as Southern Patagonia (affected by glacier melting), the Brazil–Malvinas confluence, the Southern Pacific Ocean, and the entire Southern Indian Ocean. This sailing race gave a rare opportunity to measure in-situ sea surface salinity in a region where satellite salinity measurements are not reliable. Due to the decreased sensitivity of brightness temperature to salinity in cold seas, retrieving sea surface salinity at high latitudes remains a major challenge. This paper describes how the data are processed and uses the data to validate satellite salinity products in the sub-Antarctic zone. The sailing race measurements represent surface information (60 cm depth) not available from drifters or Argo floats. Acquiring measurements using round-the-world sailing races would allow us to analyse the evolution of ocean salinity and the impact of changes in the ice extent around Antarctica

Abstract

Fishers and scientists in the tropical Pacific, Atlantic and Indian Oceans are jointly designing biodegradable fish aggregating devices (bio-FADs) that are efficient for fishing. The tactic followed by most fishers to construct bio-FADs is to maintain the same conventional drifting FAD (dFAD) design (i.e., large, submerged net panels hanging from a floating raft) but replacing plastic ropes and netting with organic ropes and canvases. Results from these experiences show that the lifetime of bio-FADs made with conventional FAD designs is notably shorter than what fishers require, thus precluding their adoption. The short lifespan of these bio-FADs is due to the inefficient design of conventional dFADs, which results in major structural stress. Thus, to successfully replace plastic with organic materials and increase the lifespan of bio-FADs, a paradigm shift is needed. Bio-FAD structures should be re-designed to minimize structural stress in the water. The present study summarizes what we have learned from testing bio-FADs in the three tropical oceans, and it proposes a new concept in dFAD design, the jelly-FAD. Mirroring jellyfish, this new dFAD design will aim for quasi-neutral buoyancy, which should reduce (i) the structural stress of the FAD at sea and (ii) the need for additional plastic flotation. The jelly-FAD is not necessarily a fixed design; it is more of a change in the concept of conventional dFAD construction. Preliminary results show that jelly-FADs aggregate tuna as well as conventional FADs do, with lifespans greater than 6 months at sea. In addition, the jelly-FAD showed average drifting speeds similar to a conventional dFAD. To accelerate the adoption of bio-FADs worldwide, recommendations for jelly-FAD construction and tests are provided

Abstract

The topic of the equality of triangles, the fundamental basis for the study of geometric contents, is taught and consolidated in the eighth grade. The present research proposes the feasibility of applying the General Heuristic Program as an alternative for the treatment of the teaching content in the demonstrations of equality of triangles in the eighth grade of Basic Secondary School. The dialectical materialist method was used with the predominance of the quantitative approach and assumed a study sample of 23 students from an intentionally selected group of eighth grade. Observation, analysis of the product of the activity, and interview were applied together with other methods and techniques. These made it possible to verify the difficulties in the teaching-learning process of the contents related to Unit 2 Plane geometry and calculation of bodies, specifically on the topic of equality of triangles. This is complex for the learners since they must apply concepts, propositions as well as procedures. For all these reasons, it is necessary to use the General Heuristic Program, which is incorporated through demonstration exercises. The partial evaluation of this work gave a positive result, which shows the effectiveness of the proposal., RESUMEN El tema sobre igualdad de triángulos, base fundamental para el estudio de contenidos geométricos, se imparte y consolida en el octavo grado. La presente investigación expone la factibilidad de aplicación del Programa Heurístico General como alternativa para el tratamiento del contenido de enseñanza en las demostraciones de igualdad de triángulos en el octavo grado de Secundaria Básica. Se utiliza el método dialéctico materialista, con predominio del enfoque cuantitativo y asume una muestra de estudio de 23 estudiantes de un grupo de octavo grado seleccionado intencionalmente, en el que se aplicó la observación, el análisis del producto de la actividad y la entrevista entre otros métodos y técnicas, que permitieron constatar las dificultades en el proceso de enseñanza-aprendizaje de los contenidos relativos a la Unidad 2: Geometría plana y cálculo de cuerpos, específicamente en el tema de igualdad de triángulos. Este resulta complejo para los estudiantes, ya que deben aplicar conceptos, proposiciones y procedimientos. Por todo lo expuesto se precisa la utilización del Programa Heurístico General que es incorporado mediante ejercicios de demostración. La evaluación parcial de este trabajo brindó un resultado positivo, lo que muestra la efectividad de la propuesta.

Abstract

VII Encuentro de Oceanografía Física (EOF) - Expanding Ocean Frontiers Conference, VIII International Symposium on Marine Sciences, 6-8 July 2022, Las Palmas de Gran Canaria, España, The South Atlantic Ocean is one of the central components of the climate system as it regulates the intensity of the Atlantic South Overturning Circulation (AMOC), which determines the amount of equatorward heat gained and transported to high latitudes (Garzoli and Matano, 2011). The main goal of the SAGA10W oceanographic cruise, carried out between March 7 and April 15 2021, was installing the appropriate equipment to perform a long time monitoring of the interior-ocean zonal flows linking the eastern and western South Atlantic basins. The equipment selected to perform the monitoring as well as the logistic of its installation was not trivial. It consisted of four PIES (Pressure Inverted Eco Sounder), and three 2000- m instrumented moorings installed along 10W on the spurs of the Mid-Atlantic Ridge between 34º20'S and 19º20'S. This vertical section takes place the verge of the subtropical and tropical gyres, in a region that has been recently identified as a pathway for both the starting and returning limbs of the AMOC: the South Atlantic Gateway (SAGA). To properly install the four PIES and three moorings it was absolutely necessary to perform a previous study of the bottom topography with enough resolution to decide the right location. Considering the period of planned monitoring (4 yrs), it was absolutely necessary to adequately prepare all submerged instrumentation. The detailed multibeam scanning of the bottom relief was performed around the points selected by GEBCO. The multibeam scanning covered a 20x20 nautical mile square and consisted of 5 meridional tracks 5 miles apart that allowed to obtain a real acoustic image of the bottom relief with a spatial resolution of 25 meters. Here, we present our experience in preparing the equipments, the cruise operations and the final setup of the entire SAGA array, The Spanish Government has supported this research through project SAGA (RTI 2018-100844-b-c33). We also recognize the institutional support of the Spanish Government through the Severo Ochoa Centre of Excellence accreditation (CEX2019-000928-S)

Abstract

The definition of a sensor monitoring strategy is based on the location for water monitoring, sensor performances, data storage and transmission. For any new sensor, available instruments currently used in oceanographic studies are identified to perform comparisons. Suitable transmission technology is selected according to the test conditions: open sea, coastal areas, remote locations, etc. Sensitivity and stress tests are designed to establish confidence limits under different environmental situations, so that the results obtained in planned testing exercises are enabled to certify the performance of the new instruments. In this paper, we will address three key phases to test and certify the performance of new sensors: (1) RD basis for cost-effective sensor development, (2) sensor development, sensor web platform and integration, and (3) field testing

Abstract

Arctic sea ice is changing rapidly. Its retreat significantly impacts Arctic heat fluxes, ocean currents, and ecology, warranting the continuous monitoring and tracking of changes to sea ice extent and thickness. L-band (1.4 GHz) microwave radiometry can measure sea ice thickness for thin ice ≤1 m, depending on salinity and temperature. The sensitivity to thin ice makes L-band measurements complementary to radar altimetry which can measure the thickness of thick ice with reasonable accuracy. During the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, we deployed the mobile ARIEL L-band radiometer on the sea ice floe next to research vessel Polarstern to study the sensitivity of the L-band to different sea ice parameters (e.g., snow and ice thickness, ice salinity, ice and snow temperature), with the aim to help improve/validate current microwave emission models. Our results show that ARIEL is sensitive to different types of surfaces (ice, leads, and melt ponds) and to ice thickness up to 70 cm when the salinity of the sea ice is low. The measurements can be reproduced with the Burke emission model when in situ snow and ice measurements for the autumn transects were used as model input. The correlation coefficient for modeled Burke brightness temperature (BT) versus ARIEL measurements was approximately 0.8. The discrepancy between the measurements and the model is about 5%, depending on the transects analyzed. No explicit dependence on snow depth was detected. We present a qualitative analysis for thin ice observations on leads. We have demonstrated that the ARIEL radiometer is an excellent field instrument for quantifying the sensitivity of L-band radiometry to ice and snow parameters, leading to insights that can enhance sea ice thickness retrievals from L-band radiometer satellites (such as Soil Moisture Ocean Salinity (SMOS) and Soil Moisture Active Passive (SMAP)) and improve estimates of Arctic sea-ice thickness change

Abstract

Shelf waters near large cities, such as Barcelona, are affected not only by meteorological episodes but also by anthropogenic influence. Scientists usually use data from on-site coastal platforms to analyze and understand these complex water ecosystems because remote sensing satellites have low spatiotemporal resolution and do not provide reliable data so close to the coast. However, platforms with conventional oceanographic instrumentation are expensive to install and maintain. This study presents the scientific adaptation and initial measurements from a “patí a vela”, which is a very popular unipersonal catamaran in Barcelona. This versatile sailing vessel has been adapted to contain several low-cost sensors and instruments to measure water properties. Here, we describe the setup of a multi-parameter prototype, and then focus on results obtained using a low-cost temperature profiler. First, the temperature data are compared and validated with another conventional oceanographic instrument used in monthly oceanographic cruises. Then, field measurements between July and November 2021 are used to explore the relationship between air and water temperature in the Barcelona coastal area, showing the seasonal evolution of the temperature profile. We conclude that citizen sampling from fully sustainable sailing boats may turn into an effective strategy to monitor the urban coastal waters

Abstract

[EN] In 1987, Konstantin Fedorov, a prominent Soviet oceanographer of the time, dedicated one of his popular science talks to the salinity of the ocean and called it “The Cinderella of Dynamic Oceanology”. Fedorov said that “The fate of salinity as a physical parameter is closely related to the dynamics of ocean waters and is very similar to the fate of poor Cinderella in Charles Perrault’s fairy tale.

One of the essential elements for understanding the functioning of the oceans is precisely our ability to track the movement of the fluid patches that connect the entire marine world, including the physical environments and the organisms and communities that inhabit them.

Abstract

Four Pressure-equipped Inverted Echo Sounders (PIES) were deployed at about 10°W, between 19 and 35°S, the South Atlantic Gateway (SAGA), in order to determine the zonal flows in the South Atlantic. Those PIES will allow to observe the circulation of two water masses, the South Atlantic Central Water (SACW) and the North Atlantic Deep Water (NADW), that flow in opposite directions across the South Atlantic, between Cape town and Brazil, through the SAGA. The measurements from the PIES, together with historical hydrographic data, permit to estimate the profiles of temperature and salinity of the water column, and therefore the density. Besides, using the thermal-wind equation, it is possible to retrieve the geostrophic velocity from an array of PIES. In order to get those estimations of temperature and salinity, it is necessary to determine the Gravest Empirical Mode (GEM), a relationship between the acoustic travel time observed by the PIES and the historical observations of salinity and temperature in the study area. In this work, we will show the GEM estimated for the SAGA, calculated using historical hydrographic data from CTDs and Argo Float, as well as, the estimations of the error in the geostrophic transport.

Abstract

Monitoring water transparency provides an indicator of the environmental status of the water body. One parameter to estimate the water transparency is the light diffuse attenuation coefficient (Kd) (Mobley, 1994). This parameter is of particular interest because it advises about phytoplankton concentrations or levels of dissolved organic and inorganic compounds. It is especially relevant in coastal areas and lakes strongly affected by anthropogenic activities. 90% of the diffusely reflected light from a water body comes from a surface layer of water within a depth of 1/Kd. Therefore, remote sensing can be an ideal tool for monitoring water transparency. With an increase in remote sensing data availability over the past decade, there has been a rise in the in situ data available for calibration and validation of satellite measurements (Topp et al., 2020). However, the current satellite measurements for monitoring coastal and inland waters are still evolving and remain challenging because of the spatial scales that satellite measurements represent (Tyler et al., 2016). Therefore, to improve data coverage in these zones, in situ irradiance measurements are still required. There is a growing worldwide need to explore cost-effective data acquisition to generate knowledge for sustainable natural resource management (Buytaert et al., 2016; Loiselle et al., 2016; Pham et al., 2015). This need to develop novel approaches for monitoring environmental data is reflected in the recent growing attention to citizen science (Njue et al., 2019). Citizen science promotes the collaboration between non-professionals and scientists and in a two-way process. Citizens can engage in various degrees from co-design and co-creation, through problem definition, data collection, analysis, and dissemination of results, to participate as interpreters of information and sensors (Shirk et al., 2012; Haklay, 2013; Chapman and Hodges, 2017). One of these in-situ sensor systems is the low cost and DIY

In the framework of the H2020 project MONOCLE (Multiscale Observation Networks for Optical monitoring of Coastal waters, Lakes and Estuaries), we have developed an improved version of the KdUINO (Bardaji et al., 2016) consisting of a moored instrument used to assess water transparency. This new version, the KduSTICK, estimates Kd near the surface in real-time following these specifcations: cost- efective, portable, real-time monitoring and easy to use with minimal training. This instrument transmits data by using the Internet of Things (IoT) networks.

45. Underwater annular irradiance: New concept to measure the light diffuse attenuation coefficient through the KduSTICK, a Do-It-Yourself device

Abstract

Measuring water transparency allows us to monitor the water body's environmental status. One parameter to estimate water transparency is the light diffuse attenuation coefficient (Kd). This coefficient is of particular interest in water quality monitoring programs. The Kd describes the light extinction as function as the depth of downwelling irradiance, Ed. However, self-shading by the instrument itself can cause errors in Ed estimations. To avoid this effect, relative complex structures must be required to install the sensors that limit the vertical resolution of Ed measurements. Here we propose to use optical sensors in an annular-shape distribution to mitigate these limitations. For this, we introduce a new concept: the annular irradiance, Ea. We first compute the optimal angle to avoid self-shading while maximizing the light captured by the sensor. Second, we assess the robustness of the corresponding diffuse attenuation coefficient, Ka, in different scenarios of water types, solar angle and cloud coverage. Finally, we correlate Ka measurements with Kd at PAR region, and we derive empirical functions from translating Ka to Kd measurements. This new coefficient is the basis of the new generation of the KdUINO instrument (Bardaji et al., 2016) as a KduSTICK, which estimates the near-surface light extinction coefficient based on Ka measurements. Since the design of the instrument avoids self-shading, the device is expected to be particularly useful in those underwater environments where high vertical Ed resolution is required. Furthermore, instruments based on this light-sensing approach are much simpler to deploy and maintain, and it is possible to design low-cost and Do-It-Yourself (DIY) versions. All these features facilitate its use for non-academic users, making the KduSTICK an optimal instrument to be used in Citizen Science water quality monitoring programs

Abstract

The encountering of the subtropical Brazil Current (BC) and the subantarctic Malvinas Current (MC) along the western margin of the Argentine Basin forms the Brazil-Malvinas Confluence (BMC), one of the most intense open-ocean fronts in the world ocean and a site for the formation of intermediate water masses. Here, we provide a comprehensive description of the BMC based on physical and biogeochemical data – hydrographic stations, profiling floats and subsurface drifters – gathered in March 2015. We use these data in order to characterize the impinging and outflowing currents and to describe the cross- and along-frontal thermohaline structure. In addition, we compare the in-situ measurements with both climatological data and the Mercator Ocean eddy-resolving reanalysis. The hydrographic sections illustrate the contrasting properties between the two western boundary currents: warm, salty, nutrient- and oxygen-poor oligotrophic subtropical waters carried southward by the BC and the cold, fresh, oxygen- and nutrient-rich subantarctic waters carried northward by the MC. The frontal system is also characterized by the presence of thermohaline intrusions, with the cross-frontal gradients and along-front velocities sharpening as the colliding currents shape the frontal system. We also observe brackish waters spreading on top of the frontal jet as a result of both the confluence dynamics and off-shelf advection favored by north-easterly winds. These low-salinity waters are positively correlated with surface ageostrophic speeds over the frontal jet. The cruise data illustrates the high regional and mesoscale variability as compared with climatological conditions, and further document the submesoscale subsurface complexity, which is not properly captured by available operational models

Abstract

En la actualidad las empresas tecnológicas están tendiendo hacia la arquitectura basada en microservicios frente a arquitecturas monolíticas. Esta nueva arquitectura a pesar de ser algo más compleja de desarrollar, soluciona muchos de los problemas de los programas monolíticos, como la localización de errores, el despliegue, el trabajo con mucho desarrolladores, entre otros problemas. Aunque los microservicios nos plantean otros dilemas, como puede ser la comunicación entre todos los módulos que forman la aplicación. A lo largo de este Trabajo de Fin de Grado se va a realizar un análisis de la Arquitectura Basada en Eventos, una forma de comunicación entre microservicios alternativa a la comunicación via REST, forma de comunicación predominante actualmente. Se puede dividir en dos partes, por un lado habrá un análisis más teórico y por otro lado se implementarán dos ejemplos de uso y de esta manera poder hacer un mejor análisis y ver si merece la pena la arquitectura en situaciones reales. El proyecto se ha realizado para la empresa Indra Sistemas, S.A, más específicamente para el departamento de arquitectura. Que incluirá parte de la documentación del análisis en su Marco de Referencia y se incluirán los ejemplos implementados como aceleradores para futuras implantaciones de la arquitectura. Esta arquitectura se basa en la generación de eventos al producirse un cambio de estado en el sistema, estos eventos se envían a un gestor de eventos que se encargará de transmitir los mensajes al resto de microservicios que estén suscritos y que se encargarán de procesarlos y realizar las operaciones pertinentes. En la primera parte se ha realizado un estudio de esta arquitectura buscando información teórica sobre la implantación y a través de esta información sacar conclusiones, ventajas, desventajas de su uso. Se harán diversas comparaciones con la que es su alternativa más directa, las peticiones REST y de esta manera se verá en que momentos es mejor usar un método u otro basándonos en complejidad, resistencia a fallos, consumos de recursos, etc. Además veremos las tecnologías con las que se puede implantar y la recomendaciones personales. En la segunda parte se han desarrollado dos módulos. Por un lado tenemos un sistema de ejemplo, que hará uso de EDA para la comunicación y kafka como gestor de eventos. Está formado por un productor que al tratarse de un ejemplo será un simulador que generará eventos con información aleatoria con una estructura basada en estado de vuelos. A parte tenemos varios consumidores que procesarán estos eventos. Todos ellos desarrollados en Spring. Por otro lado tenemos un servicio que actuará como un monitor del gestor de eventos, en el que podremos ver estado, mensajes, temas y consumidores. De esta forma podremos ver diferentes métricas de una manera visual, sin tener que entrar en la configuración de nuestro gestor de eventos y obtener información del sistema.
