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.
Scientists have developed new framework for assessing likely impacts of dredging on coral populations, and for evaluating the timeframes and likelihood of population recovery from impacts.
Scientists have tested a breakthrough in sensing sediment risks to reefs that uses bundles of fibre optic sensors and hundreds of countersunk holes to mimic coral.
An examination of whether dredging operations suspended during generic windows of environmental sensitivity could reduce the impacts on marine life has found the marine invertebrates, seagrasses and macroalgae too diverse to be covered by a one-size-fits-all approach.
Early stages of fish life, such as eggs and larvae, are most likely to suffer lethal impacts from dredging-related stress according to new research.
WAMSI science discovers a new bioindicator to assist with monitoring sediment-related stress in corals - mucus.
Three new WAMSI reports have been released on the primary producer responses to dredging.
Researchers have compared the impact low light and suspended sediment particles have on coral and found that, of the two events associated with dredging, several coral species are more likely to be affected by the loss in light intensity.
Understanding whether sponges can survive in turbid water, and being covered in sediment from dredging operations are important questions scientists are asking.
New research results help predictions about whether seagrass can recover from dredging associated with large port developments, and if so, how quickly.
