Sea ice thickness from SMOS measurements. The retrieval is based in a hybrid approach, combining the Burke emission model (Burke et al., 1979) with a machine learning algorithm. The emission model is used to generate the dataset that is then used to train a Random Forest algorithm. The sea ice thickness is retrieved only up to 1 - 1.5 m of thickness due to the limited sensitivity at the L-band. This maximum retrievable thickness is not yet included in the product but will be in the future; for safety trust values only up to 1 m, ARCTIC-MON project (PID2021-125324OB-I00), from Agencia Estatal de Investigación (AEI), This work contributes to the Institut de Ciències del Mar "Severo Ochoa Centre of Excellence" accreditation CEX2024-001494-S funded by AEI 10.13039/501100011033 of the Spanish Ministry of Science and Innovation, Daily netCDF files containing the grided sea ice thickness estimations from SMOS, Peer reviewed

The Marine Biological Reference Collections (CBMR) are located at the Institute of Marine Sciences (ICM-CSIC) in Barcelona, Spain. The CBR are a Unit of Service where around 15000 referenced species are preserved, catalogued and maintained for their study. The most represented marine groups at the CBMR are fish, crustaceans, molluscs and echinoderms, but also other groups are present. The studies based on the CBMR specimens are focused on biodiversity, biogeography, taxonomy (type species), invasive and alien species, and genetic analysis. Several PhD theses have also been carried out in collaboration with the CBMR. The CBMR are a reference point for the marine biodiversity of the Mediterranean Sea, but in their facilities the CBMR also hold specimens from all the oceans (Atlantic, Pacific, Indian, Antarctic and Arctic). The Collections are constantly receiving new specimens and updating. The main sources of specimens are oceanographic surveys and different kind of sampling programs carried out by the research projects run by the ICM-CSIC. However, the CBMR have also received (in the past and currently) different collections donated by naturalists, researchers, other institutions, and particulars. The CBMR were created in 1981, in the earlier history of the ICM-CSIC, by Jaume Rucabado, Domingo Lloris and Concepción Allué. The Collections were later recognized and catalogued by the Spanish Ministry of Culture in 1990. In the last decade, the CBMR initiated a new stage where the information was digitized and the physical preservation of specimens updated to the new rules (such as change from formaldehyde to ethanol). The CBMR are now part of GBIF (Global Biodiversity Information Facility), thus making public and available all data collections and their metadata. We have also incorporated the use of Geographical Information Systems (GIS) to monitor and study the geographical distribution of our specimens and moreover, the CBMR started to act as repository of DNA voucher collections for genetic analyses. As a unit of service of the ICM-CSIC we think that education and outreach of marine science is of crucial importance for the society and for that reason the CBMR take active part in several outreach activities with schools, universities and general public.

Se evaluó la distribución espacial, en términos de probabilidad de ocurrencia y biomasa, de las tres principales especies de pequeños peces pelágicos, anchoa (Engraulis encrasicolus), sardina (Sardina pilchardus) y alacha (Sardinella aurita), en la plataforma continental ibérica dentro de la subárea geográfica (GSA) 06, con especial atención a la Zona de Especial Protección para las Aves (ZEPA) ES0000512. Para realizar estas estimaciones, se integraron tres bases de datos independientes: datos de campañas oceanográficas MEDITS (1999-2023), registros de capturas reportadas en los diarios de pesca de buques arrastreros y cerqueros (2020-2024), y variables ambientales (1999-2025), todo ello incorporado en modelos avanzados de distribución de especies. En general, las áreas altamente productivas situadas alrededor y al sur del Delta del Ebro concentran, de forma consistente a lo largo de la serie temporal (1999-2025), las mayores probabilidades de ocurrencia y biomasas para las tres especies. También se observan probabilidades de ocurrencia y biomasa relativamente elevadas en el área marina comprendida entre el Cabo de la Nao y el Cabo de Palos, aunque la biomasa estimada en esta zona es comparativamente menor que en las aguas circundantes al Delta del Ebro. Las limitaciones inherentes a las metodologías empleadas en la recopilación y análisis de los datos, junto con las características de los modelos desarrollados, sugieren que los mapas de probabilidad de ocurrencia basados en datos MEDITS constituyen la representación más realista y verosímil de la distribución espacial de estas especies. No obstante, cabe señalar que las series temporales alternativas permiten una reconstrucción estacional más detallada de la distribución de las especies, ya que no están restringidas a los meses de muestreo de MEDITS, que se limita a un periodo concreto del año (junio y julio). Esta complementariedad metodológica puede ser útil para abordar dinámicas anuales que no quedan reflejadas en los mapas basados exclusivamente en datos MEDITS, Proyecto StelarMed (Pleamar) financiado por Corys.-- This work contributes to the Institut de Ciències del Mar "Severo Ochoa Centre of Excellence" accreditation CEX2024-001494-S funded by AEI 10.13039/501100011033 of the Spanish Ministry of Science and Innovation, 1.

[Aim] As a consequence of globalisation, biological invasions have become an increasing concern due to multifaceted ecological and socio-economic impacts on biodiversity and ecosystem services. Despite the increasing availability and accessibility of data, a comprehensive assessment of established non-native species and their distribution in the Iberian Peninsula has not been conducted so far., [Location] Iberian Peninsula, including Spain, Portugal, Andorra, and Gibraltar., [Methods] We compiled a harmonised dataset of 1273 established non-native species from multiple regional, national, and global sources. We analysed taxonomic composition, introduction pathways, and native biogeographic realms. Temporal patterns were assessed using first-record data, while spatial patterns were mapped using high-resolution occurrence data from GBIF and national databases., [Results] The majority of established non-native species are vascular plants and insects, specifically of the classes Magnoliopsida and Insecta and the families Asteraceae and Formicidae, respectively. Overall, the most common pathways of introduction were escapes from human facilities and transport-related mechanisms (contaminant and stowaway), but their importance varies among countries. Established non-native species were mostly native to the other regions within the Palearctic, followed by the Nearctic and Neotropical realms. Regarding the time of introduction, first records increased steadily until the last decades of the 20th century, when the introduction rate slowed down; yet new introductions persist. Finally, our spatial analysis identified that areas with high human population density and coastal zones recorded the highest number of established non-native species., [Main Conclusion] The Iberian Peninsula hosts a high number and diversity of established non-native species. Given the ongoing rise in cumulative introductions and the role of unintentional human-driven pathways, strengthening prevention measures is vital to reduce future invasions. However, with many non-native species already established, effective management efforts are equally crucial to curb further spread and mitigate consequent impacts, especially in areas of conservation interest., RS was supported by the Portuguese Foundation for Science and Technology (FCT) through national funds under the project MULTI-CRASH: Multi-dimensional ecological cascades triggered by an invasive species in pristine habitats (PTDC/CTA-AMB/0510/2021) (https://doi.org/10.54499/PTDC/CTA-AMB/0510/2021).
