Cuttlefish are in potential danger if the BHP desalination plant goes ahead in the Spencer Gulf. The video below is from ABC’s Catalyst program & gives insight into why the BHP desalination plant may affect Cuttlefish numbers, and, in time may even lead to their extinction.
Point Lowly, at the top of Spencer Gulf is a Cuttlefish breeding area. The extra salt pumped back into the gulf will result in higher levels of salinity, which affects growth and mortality of the Cuttlefish eggs. BHP have said that they have taken this into account. However, Oceanographer Associate Professor Jochen Kaempf has stated that the ‘dodge tide’ which happens 3-5 times a month has the ability to stir up & move the toxic sludge resulting from salt dumping further into the Cuttlefish breeding environment.
These are highly intelligent, unique and amazing creatures that need to be protected, so please watch the video & if you would like to find out more about the desalination plant, download the BHP report below.
The organisers of Pt Noarlunga Open Water Swim have generously donated the proceeds from an auction held on the swim day to the Friends of Gulf St Vincent. Thank you so much, we will endeavour to invest this in our Gulf wisely.
See below a letter from a concerned citizen about the proposed hillside mine at Pine Point.Hi Val Thankyou for listening to my concerns today. As you are now aware I am concerned about the damage that will be done to a very unique part of our South Australian coast line once a road is built along the top of the cliffs to skirt the proposed Hillside Mine at Pine Point. I believe the colours in the cliffs rival the cliffs of Rainbow Beach in Queensland which are a tourist attraction for that state. In thinking this, I may be overselling them, but I do not think so. The fact is few people have seen these cliffs for they can only be reached on foot, even though they begin just past the first head land, about 200 metres from the car park. I am anxious to get second opinions. With so many concerns being raised by locals about the proposed mine, people are overlooking the destruction that will occur to this unique coastal asset. When the tide is in, the little bays with the coloured cliffs behind, provide a beautiful and peaceful beach walk. Unfortunately this will be lost forever next year, once gullies are filled in, tops of cliffs levelled and rubble pushed down the cliff face, in order to build the new main road that will run along the top. Regretfully I think the mine will go ahead which will be a tragedy for all generations that follow ours. Taking the road inland would however at least be one good thing that could be done for the generations that follow ours. Enclosed are a few photos I took on my phone at Easter. These photos include a random shot which shows the incredible range of rocks that are scattered all along the foreshore, another feature of this area. My hope is that people will take notice of these cliffs before it is too late, and if they agree with me, then action will be taken to see that the road is redirected inland, not along the coast.

Interesting article on the PLOS One site:
Anthropogenic litter is present in all marine habitats, from beaches to the most remote points in the oceans. On the seafloor, marine litter, particularly plastic, can accumulate in high densities with deleterious consequences for its inhabitants. Yet, because of the high cost involved with sampling the seafloor, no large-scale assessment of distribution patterns was available to date. Here, we present data on litter distribution and density collected during 588 video and trawl surveys across 32 sites in European waters.
We found litter to be present in the deepest areas and at locations as remote from land as the Charlie-Gibbs Fracture Zone across the Mid-Atlantic Ridge. The highest litter density occurs in submarine canyons, whilst the lowest density can be found on continental shelves and on ocean ridges. Plastic was the most prevalent litter item found on the seafloor. Litter from fishing activities (derelict fishing lines and nets) was particularly common on seamounts, banks, mounds and ocean ridges. Our results highlight the extent of the problem and the need for action to prevent increasing accumulation of litter in marine environments.
We thought this article was very interesting.
It was written by Jason Tetro – Microbiology, Health & Hygiene Expert, on the Huffington Post website. This kind of issue affects every beach. This was written in the US, as they head into Summer (lucky!)

At this time of year, almost everyone is awaiting the inevitable end to winter and the beginning of the warmer weather of spring. But many of us cannot wait for Mother Nature and instead journey to one of a plethora of pleasant places famous for their warmth, both climactic and interpersonal. Amongst the most popular destinations, including Florida, California and the Caribbean, exist some of the most desirable beaches where millions congregate to take in the joys of sun, sea, sand, and unfortunately germs.
Sylvia Earle is the leading lady of marine biology, in fact the leading person full stop. Here she explains why the oceans are important & how we can protect them. She tells us about her one wish to change the world & is a total inspiration. Well worth watching!
