Temperate and subtropical sandy beach surf zones present diverse and abundant fauna that are important in local food webs. However, dynamics of these fauna have been poorly studied in tropical areas. The aims of the present study were to describe the small swimming surf-zone fauna (∼1-5mm in length) of two Ecuadorian sandy beaches, determine whether this fauna varies with beach, season or tide, and explore the environmental factors correlated with faunal variability. Beaches were sampled in wet and dry seasons during high, mid- and low tide (2001-2002) by using a hyperbenthic sledge. Beaches were inhabited by an abundant and diverse fauna (>1200 individuals per 100m2 and >30 taxa), where most individuals were in their early life stages (65%), and the dominant taxa included mysid shrimp (>40% of individuals) and fish and crab larvae (>25 taxa). Composition of groups that are present during their entire life or only early life stages varied most strongly between beaches, potentially because of differences in wave exposure and the influence of an adjacent river, and between seasons with changes in coastal oceanic currents. These results suggest that despite the environmental stability often portrayed for tropical environments, Ecuadorian surf-zone fauna are spatially and temporally variable. © CSIRO 2016.

This paper describes the design and construction of a Low Cost Autonomous Underwater Vehicle prototype for Antarctic Exploration to use it in the Ecuadorian Expedition to the Scientific Base Pedro Vicente Maldonado in Antarctica. This AUV can work as a platform to transport scientific payload in a determined path. The AUV length is less than 2m. Results of some systems of the AUV from laboratory, sea trials and Antarctic environment are show. © 2011 IEEE.

The pacific border of the South American plate presents a more or less symmetrical sinuosity, with a central concave curvature (the Arica Angle located between two side rays along Chile and Peru) and ending in convex arcs (the Patagonian and Talara arcs, respectively). The width of the continental and coastal margins varies significantly according to the geometry of the border. The continental margin of Ecuador corresponds to the northern part of the Talara Arc. Three different segments showing different coastal geomorphology and continental platform characteristics are identified from north to south: the northern segment (Mataje River-Galera Point) shows a wide continental shelf and slope, the upper subducted slab of the subduction plane presents a low dip; the central segment (Galera Point- Santa Elena) stands in front of the Carnegie Ridge, and presents a moderate uplift in the Manta Peninsula, in front of the Carnegie Ridge, and the upper subduction plane is subhorizontal; the southern segment includes the side and inner coasts of the Gulf of Guayaquil, below the gulf the subduction plane shows a low dip. A comparison with published 3D numerical modelling of curved subduction suggests that the geometry of the continental boundary has a significant effect on uplift or subsidence along the continental margin. Also, the subduction of asperities in the trench, such as the Carnegie Ridge, may change the coastal motion from subsiding to uplifting, as is observed in the Esmeraldas area. There is no clear evidence of a shelf developed during the Last Glacial Maximum (LGM) sea-level lowstand, probably due to the vertical motion - uplift or subsidence - observed all along the coastal margin. © The Geological Society of London 2014.

In this paper we explore the implementation of a dynamic emergency system. The proposed system uses the already implemented sensors and cameras, supplemented with task oriented sensors, in a Distributed/Wireless Sensor Networks (DSN/WSN) architecture to gain knowledge of the building environment conditions such as fires, gas leaks, corridors usage among others. With the collected information, the system, by using routing algorithms, will generate, dynamically, the best routes to evacuate the premises. The route generation takes into consideration not only the data provided by the sensors but also the nature of the emergency. This approach avoids or minimize potential risk from, for example, stored goods or the, current, status of the emergency exits, maximizing the number of routes so the evacuation of attendees and ingress of emergency personal can be done in the safest and fastest way possible. The system will inform about the egress routes and ingress routes thought the use of dynamic visible signs. In order to clarify and illustrate the proposed solution a case study for a sport stadium is also presented. © 2003-2012 IEEE.
