Abstract. The last few decades have seen dramatic changes in the hydrography and biogeochemistry of the Mediterranean Sea. The complex bathymetry and highly variable spatial and temporal scales of atmospheric forcing, convective and ventilation processes contribute to generate complex and unsteady circulation patterns and significant variability in biogeochemical systems. Part of the variability of this system can be influenced by anthropogenic contributions. Consequently, it is necessary to document details and to understand trends in place to better relate the observed processes and to possibly predict the consequences of these changes. In this context we report data from an oceanographic cruise in the Mediterranean Sea on the German research vessel Maria S. Merian (MSM72) in March 2018. The main objective of the cruise was to contribute to the understanding of long-term changes and trends in physical and biogeochemical parameters, such as the anthropogenic carbon uptake and to further assess the hydrographical situation after the major climatological shifts in the eastern and western part of the basin, known as the Eastern and Western Mediterranean Transients. During the cruise, multidisciplinary measurements were conducted on a predominantly zonal section throughout the Mediterranean Sea, contributing to the Med-SHIP and GO-SHIP long-term repeat cruise section that is conducted at regular intervals in the Mediterranean Sea to observe changes and impacts on physical and biogeochemical variables. The data can be accessed at https://doi.org/10.1594/PANGAEA.905902 (Hainbucher et al., 2019), https://doi.org/10.1594/PANGAEA.913512 (Hainbucher, 2020a) https://doi.org/10.1594/PANGAEA.913608, (Hainbucher, 2020b) https://doi.org/10.1594/PANGAEA.913505, (Hainbucher, 2020c) https://doi.org/10.1594/PANGAEA.905887 (Tanhua et al., 2019) and https://doi.org/10.25921/z7en-hn85 (Tanhua et al, 2020).

Abstract. The last decades have seen dramatic changes in the hydrography and biogeochemistry of the Mediterranean Sea. The complex bathymetry, highly variable spatial and temporal scales of atmospheric forcing and internal processes contribute to generate complex and unsteady circulation patterns and significant variability in biogeochemical systems. Part of this variability can be influenced by anthropogenic contributions. Consequently, it is necessary to document details and to understand trends in place to better relate the observed processes and to possibly predict the consequences of these changes. In this context we report on data from an oceanographic cruise in the Mediterranean Sea on the German research vessel MARIA S. MERIAN (MSM72) in March 2018. The main objective of the cruise was to contribute to the understanding of long-term changes and trends in physical and biogeochemical parameters, such as the anthropogenic carbon uptake and to further assess the hydrographical situation after the major climatological shifts in the eastern and western part of the basin, known as the Eastern and Western Mediterranean Transients. During the cruise, multidisciplinary measurements were conducted on a predominantly zonal section throughout the Mediterranean Sea, contributing to the global GO-SHIP repeating hydrography program and adhering to the GO-SHIP requirements.

Recollemos nesta colección os oito traballos premiados no que foi a segunda edición do Premio UDC Sustentabilidade a Traballos de Fin de Grao e Mestrado, correspondente ao ano 2019. A resolución desta convocatoria fíxose pública o 5 de xuño de 2020, Día Mundial do Medio Ambiente, e con ela a UDC celebrou a efeméride sen a calor dun acto presencial, no momento da saída do período de estrito confinamento requirido pola alarma sanitaria da COVID-19. Un ano antes a UDC emitía unha declaración institucional relativa ao estado de emerxencia climática e ecolóxica do planeta. Nesta nova situación, toda a humanidade percibiu a punta do iceberg dos graves prexuízos que nos trae a destrución da biodiversidade. Velaí o recoñecemento do problema ambiental, xunto co do cambio climático e o esgotamento dos recursos e a contaminación, como verdadeiro desafío das xeracións actuais. Un desafío de dimensión universal e local a que a UDC non debe nin pode permanecer allea.
