[ES] El estudio de las inscripciones que se conservan en los tres cementerios ingleses de Canarias, así como de los propios monumentos funerarios en los que estas se inscriben, permite un acercamiento al ars moriendi, pero también a los mecanismos de autorrepresentación de los miembros de la comunidad británica radicada en Canarias cuyos restos reposan en estas necrópolis. El presente estudio pretende analizar estas escrituras últimas en el contexto de una historia social de la cultura escrita en Canarias que cuenta, como elemento de diferenciación con respecto a otras regiones españolas, con una importante presencia británica, evidenciada en la mayor concentración de cementerios protestantes de todo el país.

[EN] Since the industrial revolution, anthropogenic CO2 emissions have caused ocean acidification, which particularly affects calcified organisms. Given the fan-like calcified fronds of the brown alga Padina pavonica, we evaluated the acute (shortterm) effects of a sudden pH drop due to a submarine volcanic eruption (October 2011–early March 2012) affecting offshore waters around El Hierro Island (Canary Islands, Spain). We further studied the chronic (long-term) effects of the continuous decrease in pH in the last decades around the Canarian waters. In both the observational and retrospective studies (using herbarium collections of P. pavonica thalli from the overall Canarian Archipelago), the percent of surface calcium carbonate coverage of P. pavonica thalli were contrasted with oceanographic data collected either in situ (volcanic eruption event) or from the ESTOC marine observatory data series (herbarium study). Results showed that this calcified alga is sensitive to acute and chronic environmental pH changes. In both cases, pH changes predicted surface thallus calcification, including a progressive decalcification over the last three decades. This result concurs with previous studies where calcareous organisms decalcify under more acidic conditions. Hence, Padina pavonica can be implemented as a bio-indicator of ocean acidification (at short and long time scales) for monitoring purposes over wide geographic ranges, as this macroalga is affected and thrives (unlike strict calcifiers) under more acidic conditions

[EN] The submarine volcano eruption off El Hierro Island (Canary Islands) on 10 October 2011 promoted dramatic perturbation of the water column leading to changes in the distribution of pelagic fauna. To study the response of the scattering biota, we combined acoustic data with hydrographic profiles and concurrent sea surface turbidity indexes from satellite imagery. We also monitored changes in the plankton and nekton communities through the eruptive and post-eruptive phases. Decrease of oxygen, acidification, rising temperature and deposition of chemicals in shallow waters resulted in a reduction of epipelagic stocks and a disruption of diel vertical migration (nocturnal ascent) of mesopelagic organisms. Furthermore, decreased light levels at depth caused by extinction in the volcanic plume resulted in a significant shallowing of the deep acoustic scattering layer. Once the eruption ceased, the distribution and abundances of the pelagic biota returned to baseline levels. There was no evidence of a volcano-induced bloom in the plankton community.

[EN] It is generally assumed that episodic nutrient pulses by cyclonic eddies into surface waters support a significant fraction of the primary production in subtropical low-nutrient environments in the northern hemisphere. However, contradictory results related to the influence of eddies on particulate organic carbon (POC) export have been reported. As a step toward understanding the complex mechanisms that control export of material within eddies, we present here results from a sediment trap mooring deployed within the path of cyclonic eddies generated near the Canary Islands over a 1.5-year period. We find that, during summer and autumn (when surface stratification is stronger, eddies are more intense, and a relative enrichment in CaCO3 forming organisms occurs), POC export to the deep ocean was 2–4 times higher than observed for the rest of the year. On the contrary, during winter and spring (when mixing is strongest and the seasonal phytoplankton bloom occurs), no significant enhancement of POC export associated with eddies was observed. Our biomarker results suggest that a large fraction of the material exported from surface waters during the late-winter bloom is either recycled in the mesopelagic zone or bypassed by migrant zooplankton to the deep scattering layer, where it would disaggregate to smaller particles or be excreted as dissolved organic carbon. Cyclonic eddies, however, would enhance carbon export below 1000 m depth during the summer stratification period, when eddies are more intense and frequent, highlighting the important role of eddies and their different biological communities on the regional carbon cycle.

[ES] En este trabajo formulamos como hipótesis de partida que Canarias, como frontera meridional de Europa, en un contexto de creciente internacionalización, tiene en los mercados africanos una gran baza histórica que desempeñar. Dado el interés general que este asunto suscita entre las ciencias sociales, se requiere abordarlo desde el análisis geográfico. Para cumplimentar este estudio se emplearon las estadísticas que ofrecen organismos oficiales como el Instituto Nacional de Estadística, Instituto Canario de Estadística, Agencia Estatal de la Administración Tributaria, Instituto de Comercio Exterior y entidades internacionales como la Conferencia de las Naciones Unidas para el Comercio y el Desarrollo (UNCTAD) y la Organización Mundial del Comercio (OCM).

[ES] En Canarias, en las últimas dos décadas se ha generalizado en la actividad de ordenación territorial el empleo de las denominadas unidades de diagnóstico, que fueron reguladas en 1995 por el Decreto 35/95 de Evaluación Ambiental (hoy derogado). Las unidades ambientales homogéneas se han convertido en una herramienta del planificador. La validez de las mismas, los problemas y ventajas que ofrecen en la práctica, es analizada en este artículo de cara a la ordenación y gestión litorales. Desde la praxis se valora la eficacia de esta metodología en las costas orientales de Canarias y su posible extrapolación a otros territorios continentales, comprobando su validez y eficacia en las cercanas costas saharianas y su espacio litoral.

[ES]El ciclo del agua es uno de los procesos más estudiados y menos comprendidos en profundidad por los estudiantes de primaria y secundaria, que no son capaces de aplicar lo estudiado a la vida cotidiana. Esta realidad se traslada también a la sociedad, como se refleja en los medios de comunicación, en un área (Islas Canarias) donde la escasez hídrica está a la orden del día. Los contenidos referentes a estos temas se reparten entre varias asignaturas de ESO y Bachillerato. El análisis del conocimiento de los alumnos sobre el ciclo del agua a partir de una encuesta a alumnos de 3º de la ESO de un centro ha permitido identificar las carencias que tienen en estos aspectos.

[ES] El turismo de cruceros ha reaparecido con fuerza desde los años ochenta, acelerándose su implantación en Europa -y en particular en Canarias-, desde la siguiente década. Gran parte de los estudios sobre el turismo de cruceros se han centrado en las características de la demanda (el perfil del turista, la capacidad de gasto, los impactos que causa, etc.). Sin embargo, la literatura sobre la percepción que tienen los residentes sobre este turismo es más bien escasa y donde se centra el actual estudio, en particular en el espacio más inmediato al Puerto de La Luz y de Las Palmas.[EN] Cruise tourism is a way of taking leisure time in our society. It is an activity that has become very popular since the eighties, accelerating its presence in Europe and, particularly,in the Canary Islands since the following decade. Many of the studies on cruise tourism have focused on the characteristics of the demand (including the profile of tourists, spending power, the impacts that this activity causes, etc.). However, the literature on the residents’ perception about this tourism where this study focuses on, is rather scarce is rather scarce, particularly in the space immediately to the Port of La Luz and Las Palmas.

[ES]Este artículo aborda la noción de frontera en las sociedades marítimas de la Baja Andalucía y Canarias en el tránsito del siglo XV al XVI, caracterizándola a partir de tres grandes líneas de relación. La primera gira en torno a su conformación espacial; la segunda en las relaciones económicas que se desarrollan en su seno; la tercera en la configuración de las sociedades que habitaron esos espacios, prestando a su vez atención a las culturas transfronterizas conformadas en esas sociedades. Todo ello con el objetivo de definir semejanzas y diferencias entre ambos contextos, y entre la frontera marítima y la terrestre. [EN] This article deals with the notion of boundary in maritime societies along Atlantic Andalusia and the Canary Islands at the turn of the 16th century, which is defined by three main axes of relationship. The first one focuses on its spatial distribution; the second one, the economic relations developed within it; and the third one, in the shaping of their societies, taking into account cross-border cultures shaped within them. All of this aimed at defining similarities and differences between both contexts, and also between sea and land borders.
