Since the emergence of humanity, marine environment has provided a safety net in many ways, fostered socio-economic development, creating links between states, continents. In same time, it represents priority source food for considerable percentage population. The also creates solutions to current global problems, as potential sustainable energy future. recent decades, stability this ecosystem ...

Ballast material (organic, opal, calcite, lithogenic) is suggested to affect sinking speed of aggregates in the ocean. Here, we tested this hypothesis by incubating appendicularians in suspensions of different algae or Saharan dust, and observing the sinking speed of the marine snow formed by their discarded houses. We show that calcite increases the sinking speeds of aggregates by ~100% and li...

Most invasion histories include an estimated arrival time, followed by range expansion. Yet, such linear progression may not tell the entire story. The European green crab (Carcinus maenas) was first recorded in the US in 1817, followed by an episodic expansion of range to the north. Its population has recently exploded in the Canadian Maritimes. Although it has been suggested that this norther...

A continuous microwave system to treat ballast water inoculated with different invasive species was designed and installed atthe Louisiana State University Agricultural Center. The effectiveness of the system to deliver the required heating loads to inactivate the organisms present was studied. The targeted organisms were microalgae (Nannochloropsis oculata), zooplankton at two different growth...

This study aims to present appropriate selection methods for evaluation, analysis, and comparison between different ballast water treatment technology systems in order make good decisions selecting the most optimal system. research designed a filter device on John Lie training ship prevent marine pollution due species movement through transfer process by referring D2 standard of IMO Ballast Wat...
