WAMSI: Recovering Potential of Pilbara Seagrasses

Research from the WAMSI Dredging Science Node has provided new insight into how seagrasses in the Pilbara may recover from disturbance events such as dredging.   

While some seagrasses can potentially recover from dredging related pressures over a 200 kilometer radius, others require another meadow within five kilometers to survive, or need to be regenerated from a seed bank.

The research, which is important to the ongoing management of the region’s coastal biodiversity, has produced the first real insight into the genetic variability of the area’s seagrass and the level of connectivity among different seagrass populations.

Pilbara seagrass meadows are an important source of food and habitat for the endangered dugong, sea turtles and prawns, the latter of which makes up part of the region’s multi-million dollar commercial fishing industry.

Seagrasses tend to be found in the coastal zone and grow in soft sand and muddy sediment but some species can also grow on reefs. They are found in more shallow water to a depth of 10 meters, but can be found in clear water down to 50-60 meters.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
