Sydney Harbour: Impact of contamination studies

Many have written on the beauty and values of Sydney Harbour. Over the years water health scientists have continued to bring to the attention of politicians, waterway managers and communities consequences of continual supply of contaminants into the harbour and the management challenges which must be addressed to maintain and improve this iconic waterway. This is Bruce Thom's 200th ACS Blog Read More

Geological indicators of seabed mobility - Narrabeen Beach (Sydney, Australia)

There are many gems hidden in the unpublished literature. They can reflect our knowledge from decades ago but are just as relevant to our understanding of shoreline evolution and coastal processes today as they were when first prepared. One such report, prepared for the Australian and Overseas Telecommunications Corporation in 1988, is "Seabed mobility in south-eastern Australia - the Narrabeen Beach embayment". Read More


Many of us are obsessed with the Last Interglacial (LIG or Stage 5e MIS). Between c. 130000 and 115000, global mean temperatures appear to have been slightly warmer by 1 to 2 degrees than present. Global mean sea level appears to have been higher and ice volumes less than today. If we can improve our understanding of these factors, it not just improves our knowledge of the past, but may guide us to how future ice sheets and sea levels are responding to global warming induced by greenhouse gas emissions, not just solar insolation.

Over the past week or so, I have encountered five items of news related to coastal management that I would like to share with you. They are diverse in place and substance. It comes at a time when so many of us are concerned about the future of coastal environments and their use. Each item deserves a blog on its own, but they are all so topical and relevant that I just want to offer a summary. Read More


Just 8km north of Maitland in the NSW Hunter Valley lies the small village of Largs. It is adjacent to the growing urban precinct of Bolwarra Heights, but its rural character remains intact with its cute corner pub and the striking Soldiers Memorial Hall. This hall was originally a School of Arts erected in 1878 as part of the movement to improve literacy amongst the largely dairy farming community. In 1921 it was tastefully added to in honour of those who served in World War 1. But for me the village has another less well-known claim to fame-- it is the site of a Last Interglacial (Stage 5e) fossil bed. Read More


I have benefited from a vocation that has offered opportunities to indulge in research. It has been such a privilege. The excitement of being able to go into the field, to observe, to test ideas of others and develop one’s own hypotheses, and to be able to communicate these findings all defines this privilege. To do this with other like-minded individuals made this all the more enjoyable and creative. But this would not have happened unless more senior academics put their hope and trust in me to do the work on my terms. Read More
