An investigation into the ability of bleached corals to cope with dredging related stressors has found that several species of thermally bleached corals cannot clear sediment that has smothered them, said Western Australian Marine Science Institution (WAMSI). The study was undertaken as part of the WAMSI’s Dredging Science Node at the AIMS National Sea Simulator in specially developed tank systems. […]

The federal government has announced that 20 species of coral are now protected as “threatened” under the Endangered Species Act because global warming, disease and ocean acidification are driving them toward extinction. This decision by the National Marine Fisheries Service responds to a 2009 scientific petition by the Center for Biological Diversity seeking the Act’s […]

Progress is on schedule with the Miami Harbor deepening and widening project, including the successful construction of artificial reefs and relocation of about a thousand healthy corals. The U.S. Army Corps of Engineers, Jacksonville District, and its contractors are at the 35 percent completion mark, with more than one million cubic yards of material safely […]

Coral Morphologic divers are collecting corals and transplanting them in an aquaculture lab to save them of destruction during the Panama Canal widening project. The Panama Canal expansion project is intended to double the capacity of the Panama Canal by 2015 by creating a new lane of traffic and allowing more and larger ships to […]

Results from the culmination of five-years of groundbreaking research to understand how dredging and sediments affects corals have been released in a new paper published in Scientific Reports. One of the main themes of the $19-million Dredging Science Node, facilitated by the Western Australian Marine Science Institution (WAMSI) partnership, describes the primary cause-effect pathway and […]

New guidelines for dredge plume modelling are currently being developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in partnership with the Western Australian Marine Science Institution (WAMSI). Dredging activities form part of many coastal developments in Australia, ranging from small maintenance activities to large scale dredging campaigns which involve the removal of large […]

Coral fertilization is most sensitive to sticky inshore sediments, according to researchers working to define the effects of dredging-related pressures and natural high turbidity events, the Western Australian Marine Science Institution (WAMSI) reports. The WAMSI Dredging Science Node study involved a team of scientists from the Australian Institute of Marine Science (AIMS), The University of Western […]

The International Association of Dredging Companies (IADC) has just released their latest article named ‘ReefGuard: A Scientific Approach to Active Reef Rehabilitation’. ReefGuard, a mobile coral breeding facility provides a highly controlled environment to aid in integrating the breeding and outplanting of corals. This article gives a detailed look into how proven small-scale coral breeding techniques […]

The International Association of Dredging Companies (IADC) has just released the June 2017 edition of Terra et Aqua. Terra et Aqua is a quarterly publication of the International Association of Dredging Companies, emphasizing “maritime solutions for a changing world”, IADC said. It covers the fields of civil, hydraulic and mechanical engineering including the technical, economic […]

Results from a new dredging study in Western Australia’s Dampier Archipelago provide, for the first time, a framework for assessing likely impacts of dredging on coral populations, and for evaluating the timeframes and likelihood of population recovery from impacts. In April 2014 and March 2015 studies of coral populations were undertaken at Enderby and West […]

The U.S. Army Corps of Engineers, Jacksonville District, has just released the Miami Harbor Deepening Project one-year post-construction assessment for hard-bottom middle and outer reef benthic communities. The report includes data relevant to an assessment of temporary and permanent project effects at channel-side sites as per the Florida Department of Environmental Protection (FDEP) permit conditions for […]

The University of Miami’s (UM) Rosenstiel School of Marine and Atmospheric Science announced yesterday a two-year award from the National Oceanic and Atmospheric Administration (NOAA) to support coral conservation research. The grant will support coral propagation and restoration efforts necessary to help with the recovery of threatened coral species and increased resilience of coastal communities […]

DHI Group, an independent research and consultancy organization, has just released their latest DHI Tech Talk video, named ‘Measurement of Suspended Sediment’. Solid particles transported in the water are referred to as suspended sediments. A high level of suspended sediments may lead to serious effects such as coral bleaching (corals turning completely white due to stress) […]

A new $2 million Queensland Government program will aim to reduce the amount of sediment washing off building and construction sites and flowing into the Great Barrier Reef and Moreton Bay. Environment Minister Dr Steven Miles said that the Palaszczuk Government has provided funding to deliver a four-year urban development erosion and sediment control program […]

U.S. Senator Marco Rubio yesterday urged the U.S. Army Corps of Engineers to take the necessary measures to ensure Florida’s coral reefs are accounted for during the upcoming Port Everglades project that will allow the port to accommodate larger ships. In a letter to Jacksonville District Commander, Colonel Jason A. Kirk, Rubio highlighted the important role […]

Sediment researchers may have cracked a key to early recognition of coral stress by observing mucous build-up in response to dredge related sediment. The research undertaken as part of the Western Australian Marine Science Institution’s Dredging Science Node found that colonies of the massive stony coral Porites, located off Barrow Island, produced mucous sheets that […]

The Australian Government is providing $4.86 million for five organisations to work with landholders to address the vast issue of gully erosion in the Great Barrier Reef catchments. Under the Reef Trust Gully Erosion Control Program, five organisations will undertake projects in six priority catchments to reduce the erosion of sediment into the Great Barrier […]

WAMSI Dredging Science Node researchers have, for the first time, quantified dredging effects on seawater quality conditions, which is critical to realistic testing in the laboratory. The literature review along with the examination of some large environmental monitoring datasets from recent dredging projects provided by Chevron Australia, Woodside Energy and Rio Tinto Iron Ore, have […]

A new review has found that turbidity and sedimentation, two of the most widely recognized threats to coral reefs, can have an effect on coral reproduction before, during and after spawning. Elevated turbidity regularly occurs in shallow, tropical marine environments driven primarily by wind-driven waves but this can be exacerbated by anthropogenic activities such as […]

Researchers in the WAMSI Dredging Science Node are developing new automated scientific instruments to measure sediment deposition in the field with prototypes deployed and tested. Sediment deposition and subsequent smothering of marine habitats such as corals and seagrasses is one of the mechanisms by which dredging can impact on the environment. This pressure parameter is […]

Over a dozen South Florida businesses and environmental organizations joined Miami Waterkeeper and the Center for Biological Diversity last week in demanding that the Army Corps of Engineers revaluate its Port Everglades expansion plan in light of the recent impacts to nearby Miami’s reef during its recent port expansion. In a 15-page letter, the groups detailed […]
