Resumen: The SWOT satellite mission (Surface Water and Ocean Topography), launched in December 2022, is measuring sea surface height with a resolution an order of magnitude higher than conventional altimeters, providing an unprecedented view of the variability of the sea surface topography. This document reports the activities carried out at sea during the two campaigns of the FaSt-SWOT project (PID2021-122417NB-I00 funded by MCIN/AEI/10.13039/501100011033/ FEDER,UE). These campaigns had two main objectives: 1) participate to the SWOT satellite cal/val activities by collecting in-situ observations of fine-scale structures in the area covered by the satellite during its initial fast-sampling phase, and 2) improve the characterization and understanding of these structures by combining in-situ multi-platform and satellite data with numerical models and other computational techniques.
The FaSt-SWOT experiments were conducted in the Balearic Sea (Western Mediterranean Sea) between 25-28 April and 7-10 May 2023, using R/V SOCIB. The experiments consisted
in 2 legs both using multi-scale ship-based instruments (CTD, Moving Vessel Profiler, thermosalinograph, ADCP and GoPro action cameras), autonomous platforms (surface drifters
and gliders), and satellite observations (SST, ocean color and altimetry). In addition, 2km-resolution data-assimilative modelling simulations were produced to provide a complementary
representation of the fine-scale ocean variability. Finally, machine-learning-based optimization algorithms were also tested to define adaptive sampling strategies during the experiment.
The sampling first focused on a small anticyclonic eddy, with a diameter around 20-25km. Several cross-sections of the Moving Vessel Profiler and underwater gliders provided insights into the vertical structure of temperature and salinity fields and the associated signals in chlorophyll and dissolved oxygen. Two gliders were programmed to perform back-and-forth sections during a 3-week time with a 1-day delay between them, allowing to evaluate the temporal variability of the ocean fields at the period of repetitivity of the satellite. The second leg started 9 days after the end of the first one. A 48-hour dense radiator-like pattern was performed by R/V SOCIB, allowing to characterize the evolution of the small eddy observed during the first leg. A total of 45 surface drifters were deployed during the two phases to evaluate in-situ surface currents and their associated convergence and divergence in the vicinity of the eddy.
This report presents the details of the sampling strategy and collected measurements, also including data management aspects and description of the supporting numerical simulations
and external communication activities associated with these field campaigns.2024-01-18T16:43:47ZWorking Group on Comparative Analyses between European Atlantic and Mediterranean marine ecosystems to move towards an Ecosystem-based Approach to Fisheries (WGCOMEDA)

Resumen: The ICES Working Group on comparative analyses between European Atlantic and Mediterranean Ecosystems to move towards an Ecosystem-based Approach to Fisheries (WGCOMEDA) recently completed its second three-year cycle. WGCOMEDA was established in 2014 and works in cooperation with other groups within the ICES Integrated Ecosystem Assessments Steering Group (IEASG).
The working group objectives are: i) to set the analytical and data framework to develop common Integrated Ecosystem Assessments (IEA) exercises, ii) to advance several ongoing comparative studies on ecosystems stability, and iii) to frame comparative size- and traits-based approaches in both demersal and benthic ecosystems. To fulfil these objectives, the group focused on:
Providing a more complete understanding of the structural and functional role of ecological stability across different types of ecosystems. The group has made considerable progress on understanding the interplay between stability-diversity-resilience on both demersal and pelagic communities, conducting a resilience assessment to detect recent regime shifts, and examining the role of individual and species size in the stability of communities.
Using functional trait information to assess the structure and functioning of demersal and benthic communities across Mediterranean and Atlantic systems and to predict their vul-nerability to fishing disturbance. Trait-based approaches (TBA) has been one of the most active topics of the group, with several Atlantic-Mediterranean comparative studies, and novel regional studies developing new approaches and methods combining trait information with methods and data beyond scientific surveys. In addition, specific trait-based approaches have been developed in the benthic realm by formulating disturbance and re-sistance indices on sensitive benthic habitats.
Analyzing the link between ecological stability across different ecosystems types and eco-system properties (structure and function). Work on this topic has been initiated and will be one of the main objectives for the next cycle of the working group. This effort will evaluate the complexity of biodiversity patterns and investigate the link between ecosystem structure and stability.
Identifying methods and products to support the implementation of IEA in regional ecosystems. The group discussed pros and cons of the main IEA methods and conducted an integrated trend analysis of Atlantic and Mediterranean fish communities with the goal to identify the importance of two main global drivers: fishing vs. natural hydroclimatic variability. A user-friendly, open access shiny application and an R library were developed to apply this approach.
WGCOMEDA has collected common databases, developed novel tools, revealed common patterns and mechanism between the Atlantic and the Mediterranean as well as identified important differences that need to be consider in the future development of IEAs in contrasting ecosystems. Common gaps of knowledge have been also used to define new ToRs in the next WG COMEDA cycle which include: i) improving the assessment of the functional biodiversity, ii) better understand and integrate the complexity of marine biota, iii) investigating resilience an mechanisms of change, and iv) exploring potential options to integrate ecological and socio-economic dimen-sions.2023-06-21T07:01:23ZRevisión y Control del Plan de Vigilancia Ambiental de las obras de dragado del Puerto de Maó

Resumen: Surface Water & Ocean Topography (SWOT) is the first satellite altimetry mission to measure the elevation of nearly all water on Earth’s surface. SWOT will provide high-resolution maps of the water surface topography over the open and coastal oceans, lakes rivers and reservoirs. After two decades of preparation , SWOT was launched on December 2022. For approximately the first 180 days of the mission, SWOT is in a 1-day repeat orbit for cal/val. This document represents the cruise plan of the FaSt-SWOT field campaigns co-led by IMEDEA(CSIC-UIB) and SOCIB as a contribution to the SWOT Science Team and SWOT-AdAC consortium. FaSt-SWOT multi-platform experiments took place in the Balearic Sea in April-May 2023 during the SWOT satellite mission fast-sampling phase. The generals objectives of these experiments were (1) to validate the first observations provided by the new altimeter mission during the calibration/validation phase and (2) to improve the characterization of oceanic fine scales through the combined use of in-situ multi-platform and satellite data in synergy with numerical models and innovative computational techniques. The campaigns have assessed the actual capability to map SSH variability over a range of scales (30-100 km) traditionally not resolved by conventional altimeters. A unique aspect of the FaSt-SWOT experiments is the combination of concurrent multi-scale ship-based instruments, autonomous platforms, and satellite observations with ad hoc modeling simulations, enabling the evaluation of underlying mechanisms. FaSt-SWOT federates two multiplatform in situ experiments, combining glider, drifter, ship observations together with satellite observations and high-resolution data-assimilative numerical simulations. Advanced Observing System Simulation Experiments (OSSEs) and new tools of artificial intelligence have been performed to optimize the sampling strategies. This document includes the plans for the cruises and it will be complemented with the cruise reports.2023-05-18T06:34:58Z
