Water Rate Hike due to Inasive Mussels

Southern California's largest water supplier is set to raise rates to offset higher electrical bills, protect endangered fish and pay for cleanup associated with an invasive mussel. Board members of the Los Angeles-based Metropolitan Water District are expected to approve what amounts to a 14.3 percent increase for its water in March, officials said.

New report on AIS threat to global marine biodiversity

Some 84 per cent of the world's marine ecosystems have been infected by invasive species - and this number could be even higher due to under-reporting, according to a new study from the Nature Conservancy. Although invasive species are widely recognized as a major threat to marine biodiversity, there has been no quantitative global assessment of their impacts and routes of introduction. The report gives initial results from the first such global assessment. Drawing from over 350 databases and other sources, it synthesizes information on 329 marine invasive species, including their distribution, impacts on biodiversity, and introduction pathways. Initial analyses show that only 16% of marine ecoregions have no reported marine invasions, and even that figure may be inflated due to under-reporting. International shipping, followed by aquaculture, represent the major means of introduction. The geographically referenced and publicly available database provides a framework that can be used to highlight the invasive taxa that are most threatening, as well as to prioritize the invasion pathways that pose the greatest threat.

St. Lawrence Seaway toughens ballast regulations

The St. Lawrence Seaway Management Corporation (SLSMC, part of the Dept. of Transportation) has announced stricter ballast water management practices for the 2008 season. Beginning with the 2008 navigation season, all ocean vessels, including those with "no ballast on board," will be subjected to an inspection, covering 100 percent of ballast water tanks. This inspection process will ensure that the vessel--while still a minimum of 200 km offshore--flushed all of its tanks with salt water.

Since 2006, all ocean vessels bound for a Canadian port have been subjected to ballast water inspections, to ensure that water within the ballast tanks adheres to a minimum level of salinity of 30 parts per thousand. With the harmonization of U.S. and Canadian standards, all vessels entering the Seaway, irrespective of destination, will be subjected to the same inspection process.

K-Line introduces "green" vessel

On January 17, 2008, a new ship making its maiden voyage arrived at the Port of Hueneme. The car carrier Georgia Highway was equipped with features such as a triple hull to prevent oil spills, as well as cement ballast and silicone paint, both used to reduce the possibility of introducing invasive species to a port. The carrier is one of three of its size with such features operated by Japanese shipping company Kawasaki Kisen Kaisha Ltd., or K-Line. The company also has three smaller ships built with environmentally friendly features, including main engines that are electronically controlled to cut emissions.

The permanent cement ballast reduces the amount of water ballast the ship takes on to give it the proper weight balance. Capt. Yoshizawa said Georgia Highway also has a new type of paint on its hull that keeps organisms in the port, such as kelp or algae, from clinging to the ship. That means less drag on the ship, but it also reduces the possibility that the ship will transport something from one port to another.

The ships aren't the only ones adding green features. The Port of Hueneme has a company on site that exclusively sells biodiesel to the tugboats, oil platform boats and others.
