Occurrence of American plaice (Hippoglossoides platessoides) at Non-habitual Depths in the Northwest Atlantic, 1990–93

In 1992 and 1993 American plaice (Hippoglossoides platessoides) was detected in the catches of the Spanish fleet at depths greater than those habitual to the species (>800 m). The maximum depth was registered in Div. 3L at more than 1 400 m. The maximum yields of this species at depths over 800 m were observed in Div. 3N. The presence of American plaice at great depths was mainly detected in the first half of the year, and most predominantly at the end of winter and beginning of spring. No clear relationship between the length distribution and the depths reached were observed

POLYBIUS2020, a cost-effective underwater autonomous video system to record fishing gear selectivity performance catching fish and marine litter

Underwater video cameras are a highly versatile survey solution for marine fisheries research. The POLYBIUS2020 is a system specially designed to be used as a tool for video recording inside towed fishing gears. Its design allows for rapid installation onboard commercial fishing vessels as well as for quick reconfiguration and battery replacement. The system is based on simple commercial components to ensure low costs and the opportunity of future studies using house technology. The field experiments carried out have shown the flexibility and ability of the system to obtain key information about fishing selectivity, flora and fauna characterization and marine litter presence

Selectivity of 130 mm Mesh Size in Deep Sea Bottom Trawl Fishery in NAFO Regulatory Area

In February 1995 the European Union carried out a selectivity survey on board a Spanish commercial trawler, using the codend-cover method. The objective was to study the selectivity of 130 mm mesh size for the deep sea trawl fisheries in the NAFO Regulatory Area. One hour and four hour hauls were carried out and results obtained for Greenland halibut (Reinhardtius hippoglossoides), American plaice (Hippoglossoides platessoides), roughhead grenadier (Macrourus berglax) and threebeard rockling (Gaidropsarus ensis). For the two flatfish species, the proportion of retention increased with the duration of the haul. This increase reflected in a decrease of the corresponding selection factor. It also varied with the size of fish. The selection factor was greater in smaller individuals, and this induced an asymmetry in the selectivity curve. For the groundfish species, data were enough only to fit the four hour selectivity curves, which appeared more symmetrical than the flatfish ones

Selectivity of 130 mm Mesh Size in Deep Sea Bottom Trawl Fishery in NAFO Regulatory Area

In February 1995 the European Community carried out .a selectivity campaign on board of a Spanish commercial trawler, using the codend cover method. The objective was to study the selectivity of 130 mm mesh size for the deep sea trawl fisheries in the NAFO Regulatory Area. One hour and four hour hauls were used and results obtained for Greenland halibut, American plaice, roughhead grenadier and theebeard rockling. For the two flatfish species the proportion of retention increase with the duration of the haul. This increase, reflected in a decrease of the corresponding selection factor, also varies with the size of fish, being greater in smaller individuals, and induces an asymmetry in the selectivity curve. For the roundfish species data were enough only to fit the four hour selectivity curves, both appearing more symmetrical than the flatfishes ones

Gahnite, chrysoberyl and beryl co-occurrence as accessory minerals in a highly evolved peraluminous pluton: The Belvís de Monroy leucogranite (Cáceres, Spain)

Gahnite (ZnAl2O4), chrysoberyl (BeAl2O4) and beryl (Be3Al2Si6O18) have been found as accessory minerals in the external, highly fractionated, leucogranitic unit within the Hercynian reversely zoned Belvís de Monroy pluton (westernmost part of the Montes de Toledo batholith, Cáceres, Spain). The highly felsic (SiO2 > 72 wt.%) and peraluminous (ACNK > 1.2) character of this leucogranite, together with the high content of some incompatible elements (F, Li, B, and P), seems to be a primary consequence of fractional crystallization in a magmatic closedsystem. The high Be contents and Zn/FeTotal ratio (>0.01) are relevant factors which have favoured the precipitation of these minerals. Moreover, the Si, Al, P, B, and F activities might be high, favouring the magmatic crystallization of such exotic mineral phases together with Be-rich cordierite, F-rich micas, sillimanite and Alrich phosphates. In fact, the interplay between the silica and alumina activities likely controls the stabilization and the preferential crystallization of gahnite + chrysoberyl or beryl + chrysoberyl assemblages in mm-sized microdomains. The P–T crystallization conditions are constrained by the muscovite and sillimanite stability fields and the minimum granite Al2O3-saturated solidus, and have been estimated at temperatures between 670 and 700 °C, and pressures between 1 and 2 kbar

The evolution of the zooplankton community in the gulf of Cadiz, SW Iberian Peninsula

The Spanish Institute of Oceanography (IEO) has been conducting a multidisciplinary study of the marine ecosystem in the Gulf of Cadiz (GoC; SW Iberian Peninsula) since 2009 within the frame of the program Time Series of Oceanographic data in the Gulf of Cadiz (STOCA, in Spanish). The program maintains repeated observations along five across-shelf transects: three times a year from 2009 to 2012 and quarterly on hereafter. In this paper we present the temporal evolution of the zooplankton community in the GoC. In particular, we focused on samples from three stations located off the Guadalquivir river mouth: GD1 (20 m depth), GD3 (80 m) and GD6 (450 m). Samples were taken with bongo-40 cm paired zooplankton nets (mesh size 200 mm). Double oblique hauls were conducted from top to bottom or to a maximum depth of 200 m) while the ship was steaming at 2.5 kn. A total of 43 samples per station were included in the analysis. Samples were imaged with ZooScan. Full images were processed with ZooProcess which generated set of associated features measured on each identified object (Gorsky et al, 2010). These objects were sorted following a common taxonomic guide using the web application EcoTaxa (http://ecotaxa.obs-vlfr.fr). As a sanity check, a variable number of aliquots were directly identified by light microscopy. These results permitted the description of the mean and variable components of the plankton community, their seasonal in the context of the thermohaline and transport variability in the 2010s

Implante de cemento óseo como alternativa para la reconstrucción de piso orbitario: reporte de caso

Antecedentes: El manejo de las fracturas orbitarias es uno de los retos del trauma facial. La gama de materiales para su reconstrucción es amplia y se mantiene en crecimiento constante, no así el consenso para su uso ni la literatura que lo sustenta. Objetivo: Presentar el uso y diseno˜ del implante óseo preformado como alternativa para la reconstrucción de las fracturas de piso de órbita en edad pediátrica. Caso clínico: Varón de 7 anos, ˜ quien sufre trauma contuso en hemicara derecha. Se integra diagnóstico clínico y tomográfico de fractura de piso de órbita derecha, de tipo estallamiento, pura, con atrapamiento de músculo recto inferior y ptosis palpebral derecha postraumática. Como tratamiento se realiza con éxito reconstrucción quirúrgica a los 7 días, con colocación de implante de cemento óseo preconstruido. A las 8 semanas posquirúrgicas, el paciente presenta ptosis leve residual, sin limitación a los movimientos ni diplopía. Conclusiones: El uso de cemento óseo se puede considerar adecuado para la reconstrucción de dichas fracturas, como una alternativa más dentro de los biomateriales que pueden ser utilizados por el oftalmólogo. Consideramos que nuestro optimismo por los resultados obtenidos en este reporte de caso nos obliga a aumentar el número de pacientes para recabar mayores evidencias y mayor seguimiento a largo plazo. ABSTRAC Background: The management of orbitary fractures is one of the most challenging in facial trauma; the variety of reconstruction materials for its treatment is broad and is constantly improving, but despite this there is no consensus for its use or literature that sustains it. Objective: To present the use and design of a preformed bone implant as an alternative for the reconstruction of orbital floor fractures in the pediatric age group. Clinical case: A 7-year old male who suffered a right hemifacial contusion trauma with clinical and tomographic diagnosis of right pure blowout type orbital floor fracture with inferior rectus muscle entrapment and right post-traumatic palpebral ptosis. Successful surgical reconstruction was performed 7 days later with a pre-constructed bone cement implant. Eight weeks after surgery the patient presented with mild residual palpebral ptosis, no ocular movement limitations and no diplopia. Conclusions: The use of a bone cement implant can be considered appropriate for the reconstruction of these fractures, as another alternative to be used by the ophthalmologist among the variety of all the other materials used for this purpose. We consider that our optimism based on the results obtained in this case obligates us to increase the number of patients treated in order to gather more evidence and do larger follow u

QUIJOTE scientific results - VIII. Diffuse polarized foregrounds from component separation with QUIJOTE-MFI

We derive linearly polarized astrophysical component maps in the Northern Sky from the QUIJOTE-MFI data at 11 and 13?GHz in combination with the Wilkinson Microwave Anisotropy Probe K and Ka bands (23 and 33?GHz) and all Planck polarized channels (30-353-GHz), using the parametric component separation method B-SeCRET. The addition of QUIJOTE-MFI data significantly improves the parameter estimation of the low-frequency foregrounds, especially the estimation of the synchrotron spectral index, [beta]s. We present the first detailed ?s map of the Northern Celestial Hemisphere at a smoothing scale of 2°. We find statistically significant spatial variability across the sky. We obtain an average value of ?3.08 and a dispersion of 0.13, considering only pixels with reliable goodness of fit. The power-law model of the synchrotron emission provides a good fit to the data outside the Galactic plane but fails to track the complexity within this region. Moreover, when we assume a synchrotron model with uniform curvature, cs, we find a value of cs = ?0.0797 ± 0.0012. However, there is insufficient statistical significance to determine which model is favoured, either the power law or the power law with uniform curvature. Furthermore, we estimate the thermal dust spectral parameters in polarization. Our cosmic microwave background, synchrotron, and thermal dust maps are highly correlated with the corresponding products of the PR4 Planck release, although some large-scale differences are observed in the synchrotron emission. Finally, we find that the ?s estimation in the high signal-to-noise synchrotron emission areas is prior-independent, while, outside these regions, the prior governs the [beta]s estimation.We thank the staff of the Teide Observatory for invaluable assistance in the commissioning and operation of QUIJOTE.
