<p>During the XXXVIII Italian Expedition in Antarctica, in the framework of the PNRA RESTORE (Robotic-based invESTigation and mOnitoring Ross sEa) project the PROTEUS (Portable RObotic TEchnology for Underwater Surveys) unmanned marine vehicle (UMV) was used for carrying out an integrated 3D mapping of a portion of the Tethys Bay in the Ross Sea. PROTEUS is an innovative UMV developed by the Marine Robotics research group of CNR-INM which is particularly suitable, with its reduced size and weight, modularity, reconfigurability, and open hardware and software architectures, to operate in extreme environments as the polar ones. For performing the survey seven holes were drilled in the ice pack from which it was possible to deploy the robot in the water. Thanks to the versatility of PROTEUS, it was possible to acquire a comprehensive collection of bio-geo-chemical and physical parameters of the water column (acoustic, conductivity/salinity, temperature, depth, dissolved oxygen, turbidity and chlorophyll), acoustic and video data of the ice and the seabed. All the collected data, once processed, will be made available to the scientific community by means of FAIR <span>(</span><span>F</span><span>indable, </span><span>A</span><span>ccessible, </span><span>I</span><span>nteroperable and </span><span>R</span><span>eusable </span><span>data</span><span>) techniques following the UN Ocean Science Decade </span><span>directives</span><span>.</span></p>

La Clorofila-a es un indicador de la biomasa del fitoplancton, que puede ser utilizado para predecir la presencia de peces en el océano. Al predecir la Chl-a con suficiente tiempo, se puede utilizar en la planificación de las operaciones navales que combaten la pesca ilegal, no regulada y no reglamentada, por cuanto se identifica el lugar donde existirá mayor actividad pesquera, para incrementar su vigilancia. En este trabajo, proponemos una novel técnica basada en la aplicación de la teoría de la transformada discreta de Fourier, al modelo de regresión multivariable espacio-temporal desarrollado, que considera las variables físicas y biogeoquímicas del océano para la predicción de la clorofila-a, alrededor de las Islas Galápagos. Este trabajo considera datos de acceso libre del programa espacial Copérnico de la Unión Europea.

Abstract. A 2 years dataset of a stand-alone mooring placed, deployed in November 2020 down the Levante Canyon in the Eastern Ligurian Sea, is presented. The Levante Canyon Mooring (LCM) is a deep submarine multidisciplinary observatory deployed at 608 m depth, in a key ecosystem area. The Levante Canyon hosts a valuable and vulnerable ecosystem of deep-living Cold-Water Corals (CWC), studied and monitored since 2013 through the integrated mapping of seabed and water column. The 2 years dataset, acquired on the mooring and presented here (data from November 2020 to October 2022), includes measurements conducted with both currentmeters and CTD probes, and provides information about the hydrodynamics and thermohaline properties across almost the entire water column. The observatory is still on-going and the dataset is regularly updated. All the described data are publicly available from https://doi.org/10.17882/92236 (Borghini et al., 2022). They must therefore be preserved and are of considerable scientific interest.
