Pumice Washed Up On Our Beaches This Week + Turimetta Beach Erosion + Puffer Fish Washed Ashore - The World Where You Live!
The storms that began on Sunday, last weekend, have brought what is called 'pumice' onto our beaches by Wednesday.
Pumice is igneous rock with a foamy appearance. The name is derived from the Latin word "pumex" which means "foam". Throughout history pumice has been given many names because its formation was unclear. In former times it was called "Spuma Maris", meaning froth of the sea in Latin, because it was a frothy material thought to be hardened sea foam. It was also known as "écume de mer" in French and “Meerschaum” in German for the same reason. Around 80 B.C., it was called "lapis spongiae" in Latin for its vesicular properties. Many Greek scholars decided there were different sources of pumice, one of which was in the sea coral category.
Pumice, called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored.
Pumice is created when super-heated, highly pressurised rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurisation. The depressurisation creates bubbles by lowering the solubility of gases (including water and CO2) that are dissolved in the lava, causing the gases to rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling and depressurisation freezes the bubbles in a matrix. Eruptions under water are rapidly cooled and the large volume of pumice created can be a shipping hazard for cargo ships. The pores of pumice and pumicite can have sizes from a wide range.
Pumice has been used in the medicinal industry for more than 2000 years. Ancient Chinese medicine used ground pumice along with ground mica and fossilised bones added to teas to calm the spirit. This tea was used to treat dizziness, nausea, insomnia, and anxiety disorders. Ingestion of these pulverised rocks were actually able to soften nodules and was later used with other herbal ingredients to treat gallbladder cancer and urinary difficulties. In western medicine, beginning in the early 18th century, pumice was ground into a sugar consistency and with other ingredients was used to treat ulcers mostly on the skin and cornea. Concoctions such as these were also used to help wounds scar in a healthier manner. In approximately 1680 it was noted by an English naturalist that pumice powder was used to promote sneezing.
Pumice has been used as a material in personal care for thousands of years. It is an abrasive material that can be used in powdered form or as a stone to remove unwanted hair or skin. In ancient Egypt skincare and beauty were very important to all classes and makeup and moisturisers were widely used. One common trend was to remove all hair on the body using creams, razors and pumice stones. Pumice in powdered form was used to whiten teeth in ancient Rome. Nail care was very important in ancient China; nails were kept groomed with pumice stones and to remove calluses. It was discovered in a Roman poem that pumice was used to remove dead skin as far back as 100 BC and likely before then. It has been used throughout many eras since then, including the Victorian Era.
Today, many of these techniques are still used; pumice is widely used as a skin exfoliant. Hair removal techniques have evolved over the centuries, however abrasive material like pumice stones are still used. "Pumice stones" are often used in beauty salons during the pedicure process to remove dry and excess skin from the bottom of the foot as well as calluses. Finely ground pumice has been added to some toothpastes as a polish, similar to Roman use, and easily removes dental plaque build up. Such toothpaste is too abrasive for daily use. Pumice is also added to heavy-duty hand cleaners (such as lava soap) as a mild abrasive. Old beauty techniques using pumice are still employed today but newer substitutes are easier to obtain.
One of the Pittwater Online regular contributors, Joe Mills, sent in some photos of beach erosion at Turimetta Beach and a Puffer fish this week too - they run below so you can see how these big waves bring so much debris on to our shores and also take big sections of same back out to sea - which they will eventually return to those same beaches.
Pufferfish are scaleless fish and usually have rough to spiky skin. All have four teeth that are fused together into a beak-like form. Diet. The diet of the pufferfish includes mostly invertebrates and algae. Large specimens will even crack open and eat clams, mussels, and shellfish with their hard beaks.

New Shorebird Identification Booklet
The Migratory Shorebird Program has just released the third edition of its hugely popular Shorebird Identification Booklet. The team has thoroughly revised and updated this pocket-sized companion for all shorebird counters and interested birders, with lots of useful information on our most common shorebirds, key identification features, sighting distribution maps and short articles on some of BirdLife’s shorebird activities.
The booklet can be downloaded here in PDF file format: http://www.birdlife.org.au/documents/Shorebird_ID_Booklet_V3.pdf
Paper copies can be ordered as well, see http://www.birdlife.org.au/projects/shorebirds-2020/counter-resources for details.

Shorebirds are a group of wading birds that can be found feeding on swamps, tidal mudflats, estuaries, beaches and open country. For many people, shorebirds are just those brown birds feeding a long way out on the mud but they are actually a remarkably diverse collection of birds including stilts, sandpipers, snipe, curlews, godwits, plovers and oystercatchers. Each species is superbly adapted to suit its preferred habitat. The Red-necked Stint is as small as a sparrow, with relatively short legs and bill that it pecks food from the surface of the mud with, whereas the Eastern Curlew is over two feet long with a exceptionally long legs and a massively curved beak that it thrusts deep down into the mud to pull out crabs, worms and other creatures hidden below the surface.
Some shorebirds are fairly drab in plumage, especially when they are visiting Australia in their non-breeding season, but when they migrate to their Arctic nesting grounds, they develop a vibrant flush of bright colours to attract a mate. We have 37 types of shorebirds that annually migrate to Australia on some of the most lengthy and arduous journeys in the animal kingdom, but there are also 18 shorebirds that call Australia home all year round.
What all our shorebirds have in common—be they large or small, seasoned traveller or homebody, brightly coloured or in muted tones—is that each species needs adequate safe areas where they can successfully feed and breed.
The National Shorebird Monitoring Program is managed and supported by BirdLife Australia.
This project is supported by Glenelg Hopkins Catchment Management Authority and Hunter Local Land Services through funding from the Australian Government’s National Landcare Program. Funding from Helen Macpherson Smith Trust and Port Phillip Bay Fund is acknowledged.
The National Shorebird Monitoring Program is made possible with the help of over 1,600 volunteers working in coastal and inland habitats all over Australia.
The National Shorebird Monitoring program (started as the Shorebirds 2020 project initiated to re-invigorate monitoring around Australia) is raising awareness of how incredible shorebirds are, and actively engaging the community to participate in gathering information needed to conserve shorebirds.
In the short term, the destruction of tidal ecosystems will need to be stopped, and our program is designed to strengthen the case for protecting these important habitats.
In the long term, there will be a need to mitigate against the likely effects of climate change on a species that travels across the entire range of latitudes where impacts are likely.
The identification and protection of critical areas for shorebirds will need to continue in order to guard against the potential threats associated with habitats in close proximity to nearly half the human population.
Here in Australia, the place where these birds grow up and spend most of their lives, continued monitoring is necessary to inform the best management practice to maintain shorebird populations.
BirdLife Australia believe that we can help secure a brighter future for these remarkable birds by educating stakeholders, gathering information on how and why shorebird populations are changing, and working to grow the community of people who care about shorebirds.

Research shows that one in five Australian children aged 8 to 17 has been the target of cyberbullying in the past year. The Office of the Children’s eSafety Commissioner can help you make a complaint, find someone to talk to and provide advice and strategies for dealing with these issues.
Make a Complaint
The Enhancing Online Safety for Children Act 2015 gives the power to provide assistance in relation to serious cyberbullying material. That is, material that is directed at a particular child with the intention to seriously embarrass, harass, threaten or humiliate.
Before you make a complaint you need to have:
- copies of the cyberbullying material to upload (eg screenshots or photos)
- reported the material to the social media service (if possible) at least 48 hours ago
- at hand as much information as possible about where the material is located
- 15-20 minutes to complete the form
The Office of the Children’s eSafety Commissioner is Australia's leader in online safety. The Office is committed to helping young people have safe, positive experiences online and encouraging behavioural change, where a generation of Australian children act responsibly online—just as they would offline.
We provide online safety education for Australian children and young people, a complaints service for young Australians who experience serious cyberbullying, and address illegal online content through the Online Content Scheme.
Our goal is to empower all Australians to explore the online world—safely.
