    Abstract: Marine animals are increasingly instrumented with environmental sensors that provide large volumes of oceanographic data. Here, we conduct an innovative and comprehensive global analysis to determine the potential contribution of animal‐borne instruments (ABI) into ocean observing systems (OOSs) and provide a foundation to establish future integrated ocean monitoring programmes. We analyse the current gaps of the long‐term Argo observing system ( 〉 1.5 million profiles) and assess its spatial overlap with the distribution of marine animals across eight major species groups (tuna and billfishes, sharks and rays, marine turtles, pinnipeds, cetaceans, sirenians, flying seabirds and penguins). We combine distribution ranges of 183 species and satellite tracking observations from 〉 3,000 animals. Our analyses identify potential areas where ABI could complement OOS. Specifically, ABI have the potential to fill gaps in marginal seas, upwelling areas, the upper 10 m of the water column, shelf regions and polewards of 60° latitude. Our approach provides the global baseline required to plan the integration of ABI into global and regional OOS while integrating conservation and ocean monitoring priorities.

    Variational interpolation of high-frequency radar surface currents using DIVAnd

    Abstract: DIVAnd (Data-Interpolating Variational Analysis, in n -dimensions) is a tool to interpolate observations on a regular grid using the variational inverse method. We have extended DIVAnd to include additional dynamic constraints relevant to surface currents, including imposing a zero normal velocity at the coastline, imposing a low horizontal divergence of the surface currents, temporal coherence and simplified dynamics based on the Coriolis force, and the possibility of including a surface pressure gradient. The impact of these constraints is evaluated by cross-validation using the HF (high-frequency) radar surface current observations in the Ibiza Channel from the Balearic Islands Coastal Ocean Observing and Forecasting System (SOCIB). A small fraction of the radial current observations are set aside to validate the velocity reconstruction. The remaining radial currents from the two radar sites are combined to derive total surface currents using DIVAnd and then compared to the cross-validation dataset and to drifter observations. The benefit of the dynamic constraints is shown relative to a variational interpolation without these dynamical constraints. The best results were obtained using the Coriolis force and the surface pressure gradient as a constraint which are able to improve the reconstruction from the Open-boundary Modal Analysis, a quite commonly used method to interpolate HF radar observations, once multiple time instances are considered together.

    Effectiveness of protection of seagrass ( Posidonia oceanica ) populations in Cabrera National Park (Spain)

    Abstract: Posidonia oceanica , the dominant seagrass species in the Mediterranean, appears to be experiencing widespread loss. Efforts to conserve Posidonia oceanica are increasing, as reflected in the increase in the number of marine protected areas in the Mediterranean. However, the effectiveness of these measures to conserve seagrass meadows is unknown. In this study, the present status of the Posidonia oceanica meadows in the Cabrera National Park (Mediterranean), the only marine national park in Spain, was assessed, and the effectiveness of the conservation measures adopted was tested. This was done by reconstruction of past and present growth, quantification of the demographic status of the established meadows, and quantification of patch formation and growth rates in areas where recolonization is occurring. The meadows extended from 1–43 m deep at Santa Maria bay and from 1–33 m at Es Port. Leaf production rate of the stands examined ranged between 6.5 and 7.8 leaves shoot −1 yr −1 , with higher rates in Santa Maria than in Es Port. Vertical rhizomes elongated at rates ranging from 5.39–10.12 mm yr −1 , annual vertical growth in Santa Maria stands being larger than that in the stands developing at Es Port. Horizontal rhizomes elongated slowly (from 2.6–6.1 cm yr −1 ), and branching was sparse ( 〈 0.25 branches yr −1 axis −1 ), with maximum elongation and branching rates in areas where patches were actively colonizing. Flowering was a rare event in all the stands ( 〈 0.015 flowers shoot −1 yr −1 ). Patch formation and patch growth rates in active colonizing areas were slow, but they increased after implementation of mooring regulations in the Park. Similarly, the leaf production tended to increase, and vertical rhizome growth to decrease, in both bays following the onset of regulation measures. However, the decrease in vertical growth detected was greater at Santa Maria, where access is prohibited to visitors, than at Es Port, where boats are allowed to moor, attached to permanent weights. Shoot mortality rate was generally low (mean 0.10 ± 0.02 ln units yr −1 ) but exceeded the recruitment rate ( 〈 0.009 and 0.17 ln units yr −1 ) in 55% of the meadows examined, indicative of negative net population growth rates. Regulation of mooring activities has improved the status of the P. oceanica meadows at Cabrera National Park. The demographic analysis, however, indicated that while P. oceanica meadows at Santa Maria are in good shape, those at Es Port seem to be compromised. The observed differences in meadow status reflect the large differences in circulation inside the bays (water residence time at Santa Maria = 4 days, water residence time at Es Port = 11 days) and the anthropogenic pressure both bays support.

    Abstract: Las zonas costeras son un elemento único y singular relacionado con la calidad de vida de los ciudadanos y son también un recurso esencial sobre el que se basa la actividad turística. Hacer compatibles la calidad del medio ambiente y la preservación del patrimonio natural con la actividad económica es un reto imprescindible y además ya obligado, si queremos garantizar una sostenibilidad real, una sostenibilidad que hoy ya estamos en disposición de medir, y que es cada día más demandada por la sociedad. En particular, para asegurar una sostenibilidad de la actividad turística a medio y largo plazo se precisa de una nueva forma de gestión del litoral basada en el conocimiento, una gestión que tenga en consideración los avances científicos y tecnológicos y que permita identificar y alcanzar los puntos de equilibrio entre medio ambiente, economía y sociedad.

    Time and space variability in the eastern Alboran Sea from March to May 1990
    American Geophysical Union (AGU) ; 1995

    Abstract: An intensive field experiment was carried out from March 6 to April 30, 1990, in the eastern Alboran Sea to understand the relationship between the large‐scale circulation and the location of the transition zone between new and longer‐resident Modified Atlantic Water (MAW). The detection of a strong jet (80 cm s −1 ) of new MAW with anticyclonic curvature near the Morocco coast suggests that the Eastern Alboran Gyre (EAG) was not fully developed. A new state of the circulation in the eastern Alboran basin, intermediate between the EAG (Viúdez et al., 1995) and the Lanoix (1974) state, is presented. Also important is that the Almería‐Oran Front was not present in the upper layer, that small‐scale instabilities were detected in the northern region, and that significant nongeostrophic flows were observed. All these features are clearly indicative of the high spatial and temporal variability of a region where complex adjustments among density, velocity, and topography occur.

    A theoretical study of large sea level oscillations in the western Mediterranean
    American Geophysical Union (AGU) ; 1988

    Abstract: Large sea level oscillations (up to 1‐m amplitude and around 10‐min period) have been observed in several bays and harbors of the western Mediterranean. These oscillations appear to be associated with short‐period (10 min) atmospheric pressure fluctuations (amplitude of 1.5 mbar). Using a model with a flat shelf and a sloping‐bottom harbor, we found that these oscillations were the result of a three‐way resonant coupling between an atmospheric gravity wave, a coastally trapped edge wave, and the normal modes of a harbor. The amplification mechanism was studied for the harbor of Ciutadella. Good agreement between the predicted and the observed frequencies and amplitudes is found.
