This paper intends to explain the development of Coastal Video Monitoring System (CoViMoS) with the main characteristics including low-cost and easy implementation. CoViMoS characteristics have been realized using the device IP camera for video image acquisition, and development of software applications with the main features including detection of shoreline and it changes are automatically. This capability was based on segmentation and classification techniques based on data mining. Detection of shoreline is done by segmenting a video image of the beach, to get a cluster of objects, namely land, sea and sky, using Self Organizing Map (SOM) algorithms. The mechanism of classification is done using K-Nearest Neighbor (K-NN) algorithms to provide the class labels to objects that have been generated on the segmentation process. Furthermore, the classification of land used as a reference object in the detection of costline. Implementation CoViMoS system for monitoring systems in Cucukan Beach, Gianyar regency, have shown that the developed system is able to detect the shoreline and its changes automatically.

A new species of amphipod, Bathyporeia watkini sp. nov. from the Atlantic coasts of North Africa is described. This very characteristic species is abundant in some lagoons and estuaries near 28°N. New morphological information on B. elkaimi d’Udekem d’Acoz and Menioui, 2004 is given after specimens that were recently collected on the Atlantic coasts of southern Spain and South Portugal. The male of B. ledoyeri d’Udekem d’Acoz and Menioui, 2004 is described for the first time and new records of North African B. guilliamsoniana (Bate, 1857) and B. chevreuxi d'Udekem d'Acoz and Vader, 2005a are discussed.
