This paper presents a novel strategy to filter out images that contain redundant information when building photomosaics from the sea bottom. The goal is to alleviate computational resources and processing time in their ...

Between 30% and 75% of the total operational costs of tuna vessels are fuel-related [1]. Both these costs, with their effect on fish prices and food security [2], and the impact on climate change of the greenhouse gases ...

The degradation and impoverishment of the seabed that has been detected during last decades is the result of numerous variables, among which are uncontrolled exploitation of the seabed concerning its vulnerability, based ...

Floating offshore wind turbines present several advantages over land-based and bottom-fixed offshore wind turbines, but they are also exposed to strong environmental loads, especially wind and waves, which generate vibrations ...

This work aims to provide technical information regarding the identification and modelling of the Yellowfish Autonomous Surface Vehicle (ASV) developed at Universidad Loyola Andalucía. The goal is to have a simple model ...

In this work, we describe the development of a system that aims to deal with different communication means when operating in a network of heterogeneous systems with ad-hoc behaviour that has proved helpful in real-life ...

Autonomous Surface Vehicles (ASVs) have become a powerful tool for marine research due to their capability to make observations over a wide range of temporal and spatial scales. ASVs provide accurate, high-resolution, ...

High-Frequency Non-Invasive (HFNI) instruments are currently used in bivalve mollusks in order to use them as bio-indicators of the local conditions of the environment. Under the STRAUSS project an Arduino controlled ...

The international RAIA Observatory serves the main maritime activities of the NW Iberian coastal upwelling system. Over the last few years, the partners of the observatory have identified at least 12 key environmental risks ...

With the support of the Basque Government, offshore longlines have been used for mussel production in Mendexa (“Bivalve Mollusc Production Area”) since 2019. This area is located about 2 nautical miles from the Basque coast ...

Upgrading underwater communication capabilities for seafloor monitoring: The PLOME project’s innovative pop-up buoy concept for near-real-time data collection and transmission.

Marine mesocosms, the closest experimental approach to the marine ecosystems, are a powerful tool to study ecosystems functioning, to address those problems derived from global change and to test mitigation strategies. ...

This paper describes the behavioural tests carried out with real fish to study their behaviour and stress against the different prototypes of mini-robot fish with the aim of identifying stressors and reducing them when ...

In this study, we conducted preliminary experiments to characterize an acoustic sonar [1][2] for underwater communication. We carried on image transmission experiments and attempted to reduce reflections using insulating ...

This paper presents a low-cost compact Bluetooth sensor designed to periodically measure both in and out of water the concentration of greenhouse gases such as CO2, CH4 and N2O. For this purpose, it has several sensors and ...

Underwater cabled observatories are a key assets to monitor the oceans, providing high-resolution multi-parametric data from a wide variety of sensor systems. Their outstanding observational capabilities lead to significant ...

Intrusive sensors are widely employed in numerous industrial applications to determine the phase fraction in gas-liquid two-phase flows. Such applications include those in the chemical, nuclear, and oil industries. This ...

To improve our understanding of how marine ecosystems function, it is crucial to quantify their processes using proper spatio-temporal multiparametric monitoring techniques. Science and innovative technologies must play a ...
