Juniper Publishers -  Journal of Oceanography Abstract This is a preliminary characterisation of a bacteriocin, BacL49 produced by  Lactococcus lactis  ssp.  lactis.  This bacteriocin is significant due to its activity against  Streptococcus iniae,  a bacterial pathogen causing severe economic losses in the global aquaculture of various fish. Spot-on-lawn and microtitre plate assays were used to test antagonistic activity of the bacteriocin. BacL49 is heat and pH stable (100 °C for 60min, pH 2.5-9.5), and sensitive to proteinase K, a-chymotrypsin, trypsin and papain. BacL49 has a bactericidal mode of action and is produced during late log phase growth. BacL49 exhibits a broad activity spectrum against S. iniae, antagonising 93.75% (45/48) of  S. iniae  isolates collected from a variety of hosts and environments. The apparent molecular masses of the active protein components determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis are 5 and 54kDa. Molecular analy

Juniper Publishers -  Journal of Oceanography Introduction Coastal surface waves are critical in studying the complex marine systems and have large-scale implications on coastal engineering applications. Waves can be observed in all sizes and forms in water open to the atmosphere, depending on magnitude of the forces acting on the water [ 1 ]. Therefore, different categories of surface waves exist. One way to characterize them is based on their distinct temporal scales, associated with various generating mechanisms. For example, wind waves have a typical period of 16 seconds or smaller, which are generated locally when wind blowing over the water surface. Swells, with a period of 12-20 seconds, are waves that have traveled away from the area in which they were formed, either from a distant storm or combination of waves from different wind systems. Infragravity waves (also known as surf beat, see [ 1 ]) are long, bound waves whose period ranges from 20 seconds to the order of min

Juniper Publishers -  Journal of Oceanography Abstract Syngnathus abaster  is a pipefish whose distribution is commonly referred as encompassing the Mediterranean and Black Sea, as well as the Atlantic Coast northwards up to the Bay of Biscay. Given the species ability to endure large variation in water salinity, this euryhaline pipefish may now be encountered in a wider variety of aquatic environments, not only marine or brackish but also in purely freshwater habitats. During the last decades, information on the biology of the black-striped pipefish grew, and new data emerged. As this information derives from populations that are geographically distant, it is important to review the available data across the distribution in order to understand the more general processes occurring. While summarizing the distributional information, collected data suggests that  S. abaster  is expanding its spatial distribution in two very distinct ways, either by slowly moving north through the
