4 Pags.- 4 Figs.- 3 Tabls., [ES] : Aragón presenta en el sur de Monegros uno de los secanos más árido de España, en el entorno de humedales
salinos, tratándose de un espacio protegido dentro de la Red Natura 2000, ZEPA “La Retuerta y Saladas de Sástago”
y ZEC “Monegros”. Se cultiva cereal de invierno de barbecho largo con una limitada producción. La inminente transfor mación en regadío conllevará cambios importantes e irreversibles en los sistemas salinos debido a la dulcificación de
estos ambientes. El objetivo es monitorizar el desarrollo del cereal empleando Sentinel-2, datos de producción y el mapa
litológico disponible para identificar diferencias según el tipo del suelo. Se emplea el Índice de Vegetación de Diferencia
Normalizada (NDVI) y se analiza la firma espectral del cultivo en dos campañas de producción contrastada usando las
herramientas disponibles en la plataforma Google Earth Engine. El NDVI refleja la diferencia de producción de acuerdo
con las lluvias y es mayor para todos los cereales en parcelas sobre lutitas en la campaña de alta producción. La firma
espectral refleja la influencia del suelo incluso en el momento de máximo NDVI., [EN] Aragón presents in the south of Monegros one of the driest drylands in Spain, in the environment of saline wet lands, being a protected area within the Natura 2000 Network, ZEPA “La Retuerta y Saladas de Sástago” and ZEC “Mone gros”. Long fallow winter cereals are grown with limited production. The imminent transformation into irrigated land will lead
to important and irreversible changes in the saline systems due to the sweetening of these environments. The objective is
to monitor cereal development using Sentinel-2, production data and the available lithological map to identify differences
according to soil type. The Normalized Difference Vegetation Index (NDVI) is used and the spectral signature of the crop is
analyzed in two contrasting production campaigns using the tools available in the Google Earth Engine platform. The NDVI
reflects the yield difference according to rainfall and is higher for all cereals in plots on shale in the high production season.
The spectral signature reflects the influence of the soil even at the time of maximum NDVI., A los proyectos PID2021-127170OB-I00, financiado

4 Pags.- 5 Figs.- 3 Tabls., [ES] Se presenta una estrategia de muestreo y análisis de agua y datos multiespectrales simultáneos en tres hu medales salinos e hipersalinos de la Cuenca del Ebro, mediante vuelo de drones. Los parámetros de calidad del agua
indicadores del estado ecológico muestran correlaciones significativas con la mayoría de las bandas espectrales y sus
combinaciones. Se han analizado el índice de clorofila normalizado (NDCI) y las bandas y combinaciones homólogas a las
empleadas en la literatura con Sentinel-2. La estima de clorofila-a (Chl-a) presenta un rango desde 133.0 (±31.6) mg/m3
en la laguna de Sariñena hasta 8.5 (±9.4) mg/m3 en la de Gallocanta. La Chl-a se relaciona claramente con la reflectancia,
especialmente en el rango espectral del infrarrojo cercano (r=0.79, p<0.05), y con el índice NDCI (r=0.64, p<0.05). Las la gunas muestran patrones espectrales diferentes acordes con su estado ecológico, y consistentes dentro de cada lag, [EN] We present a strategy for sampling and analyzing water, coupled with the simultaneous acquisition of multispec tral data acquired from UAVs in three saline and hypersaline wetlands in the Ebro Basin. The water quality parameters
indicative of ecological status show significant correlations with most of the spectral bands and their combinations. The
normalized chlorophyll index (NDCI) and the bands homologous to Sentinel-2 used in the literature have been analyzed.
Chlorophyll-a (Chl-a) exhibits a range from 133.0 (±31.6) mg/m3 in Sariñena Lake to 8.5 (±9.4) mg/m3 in Gallocanta Lake.
Chl-a is closely related to reflectance, particularly in the NIR spectral range (r=0.79, p<0.05), and to the NDCI index
(r=0.64, p<0.05). The lakes exhibit different spectral patterns consistent with their ecological status, and these patterns are
consistent within each lake., Ayuda PID2021-127170OB-I00 financiada por MCIN/

nland soil salinity occurs in the Central Ebro Basin (CEB), Spain, together with gypseous soils, uncommon in Europe. Both characteristics happen in Monegros area, in the CEB, where life-threatening soils share biodiversity conservation and rainfed winter cereal. We aim to highlight the soil features governing the soil behaviour under the imminent transformation into irrigation.
We opened 17 pits in 11 plots of barley or wheat, guided by a detailed geomorphological map. The pedons were described and sampled to determine soil salinity of the saturated paste extract (ECe), calcium carbonate equivalent (CCE), gypsum, and organic matter concentrations., This research was granted by PID2021-127170OB-I00 and by TED2021-130303B-I00., Peer reviewed

2 .pdfs: 1) Resumen amplio (2 Pags.) ; 2) Póster de los autores (Maps., Figs, Fots.)., Three levels of fluvial terraces were identified in the lower Cinca River (Central Ebro Basin, NE Spain) at +233, +261, and +285 m above the present river thalweg. These terraces correspond to Lower Pleistocene levels, appear at higher altitudes than those dated at 1.27 Ma at +190 m, and higher than those dated at 1.4 Ma at +140 m, and are the highest described in the Ebro Basin. The terraces are made up of 2-4 m thick non-consolidated coarse (4-10 cm) deposits from the Pyrenees with fragments of limestone, quartzite, granitoids and andesites. The stones at the lowest terrace show interlocking in an E-W direction towards the local structural relief, indicating a meandering river course, and some show a red patina (2.5YR 5/8). This coarse layer is overlaid by a fine-grained fluvial deposit of 3-14 m, a colluvium with Tertiary limestone pebbles, and at the top, by a soil with a 130-170 cm-deep Petrocalcic horizon. This soil at the lower terrace shows a horizon sequence A (Ochric)-2Bk-3Abky (Ochric)-3km1 (Petrocalcic)-3Bkm2 (Petrocalcic)-3Bkm3 (Petrocalcic)-4Bwk (Calcic), and was classified as Thermic, Carbonatic, Fine-loamy Petrocalcic Calcixerept. Clay mineralogy is dominated by quartz, illite, paligorskite, and sepiolite. The Petrocalcic horizon has a mean CaCO3 concentration of 73%, 7.5YR reddish colour, a nodular-laminar structure with a 1-2 mm laminar layer at the top, and nodular-powdery structure in the 3Bkm3 horizon. Pseudoanticline structures appear in 3Bkm1. The morphology corresponds to the Bachman-Machette V stage of evolution. This old polygenic soil with a highly developed Petrocalcic horizon is an important record of the Quaternary environmental evolution of the Ebro Basin that increases the recorded number of terraces from 12 to 15., This research was made possible by the grant PID2021-127170OB-I00 funded by
