“…Building upon prior studies on the region that were focused on geophysical exploration or ecology of one group (Ferraro et al, 2020;Lanfranco et al, 1999;Sciberras et al, 2009), the Maltese shelf offers a good setting to improve our understanding of l/C-type carbonate system. Therefore, in order to improve the existing knowledge of non-tropical allochem assemblage, their composition, sedimentological characteristics and paleoenvironmental significance, this study aims at ground-truthing prior geophysical studies on the Maltese shelf, and to delineate the sedimentary facies and their distribution along the shelf.…”

Although ~20% of global carbonate occurs on extra-tropical shelves, our understanding of these depositional environments still lags far behind that of tropical carbonate platforms. The Maltese shelf in the central Mediterranean offers an opportunity to study in situ facies distribution in a light-dominated extra-tropical carbonate platform and the factors controlling them. The Maltese shelf visually exhibits three main facies: seagrass meadows; sand flats/bedforms and maerl. While visually distinctive, the allochem composition of the sediment does not offer a clear differentiation of all three but rather a gradient. This gradient is marked by increasing grain size with depth, a transition from green to red calcareous algae and an increase in the fraction of low Mg calcite. While some of these features could be explained by changes in light availability, other factors are also in play. Internal waves, currents and baffling by seafloor vegetation appear to play important roles in governing the sedimentary texture and composition across the Maltese shelf. The role of vegetated substrate is of greater importance in Mediterranean C-type carbonate factories and could be an important marker to identify them in the geological record.

“…In particolare, per l'isola di Linosa, grazie all'utilizzo di navi oceanografiche del CNR, tra il 2016 e il 2017 sono stati acquisiti dati ben oltre i limiti dell'AMP, che hanno permesso di osservare il reale sviluppo dell'edificio vulcanico sommerso dell'isola (Tonielli et al, 2019;Romagnoli et al, 2020). L'analisi di tutti i dati raccolti ha consentito la realizzazione di una mappa tematica dei principali ambienti sedimentari e bentonici (scala 1:15000) in un range di profondità compreso tra i 20 e i 600 m. Inoltre, la mappa è corredata sia da immagini raccolte con investigazioni ROV che dall'integrazione dalla distribuzione spaziale dei foraminiferi bentonici e dalla identificazione di specie caratteristiche di diverse tipologie di facies (Ferraro et al, 2020).…”

“…The emergence of multibeam echo sounder technology in the 1970s marked a fundamental revolution in ocean depth measurement techniques. Due to uneven seabed depth distribution and complex features like trenches and straits [1], single-beam soundings resulted in data density issues that were difficult to handle. As a result, multibeam echo sounder systems were developed based on the foundation of single-beam sounding.…”

To address the optimization of a survey vessel's navigation route, this study uses historical sea depth data from a maritime area several years ago as an example. The research employs the two-dimensional Particle Swarm Optimization (2DPSO) algorithm to calculate the direction and distance for vessel navigation while adhering to constraints, aiming to obtain the optimal route for the survey vessel. Traditional Particle Swarm Optimization exhibits rapid early-stage convergence, but slows in the later stages and is susceptible to local optima. Hence, we opt for the 2DPSO algorithm, known for its simpler structure and incorporation of penalty functions to constrain particle values. This enhances algorithm performance and minimizes the risk of falling into local optima, offering a better solution to optimal route planning.
