Precious Water

In the images from outer space blue oceans cover nearly three quarters of the surface of the earth. All but 3% of the water is salty. Most of our fresh water is locked in polar ice!


In understanding the water cycle we can see that evaporation is constantly drawing water up from the oceans into the atmosphere and eventually precipitating back down to earth as rain.

The rain refreshes and cleans the land as it washes down into the receiving waters. The run-off provides us with renewed fresh water in our streams, rivers, lakes and can help to refill our underground aquifers. Water always seeks it's own level, eventually finding it's way back to the sea again.

In the illustration to the left you can see all of the surface water rolled up into a ball on top of the mass of the planet.

Just to the right there is a much smaller blue ball that represents available fresh water. That tiny blue ball is our most precious resource!

Ports Australia Biennial Conference 21-24 October 2014

The next Ports Australia Biennial Conference which will be held in Perth is now less than 2 months away.

CSIRO; tagging a white shark


CSIRO are a truly wonderful Australian science research resource. Key result areas stretch across a wide spectrum and when it comes to the mysteries of the ocean they dive deep. They also help to educate the public.

CSIRO report on Lionfish

CSIRO Double Helix is a fantastic site for students and teacher interested in how things work.  One recent article describes Lionfish hunting strategies including invisibility tactics.

In the warm tropical ocean around the Great Barrier Reef, the lionfish hunts. Venomous fins fan out to trap a school of smaller fish. The little fish look for an escape. But this lionfish is not hunting alone.
As we grow up, we learn to share, take turns and cooperate. Now it seems lionfish use the same skills for a more deadly purpose. New research shows lionfish hunt better when they cooperate with other lionfish, and that they share the meal evenly.
Lionfish are predators and use their long, stripy fins to corner prey.

Enjoy the adventures of Ed the Bear and his partner, Steve Savage, at a beautiful shingled salt marsh in Shoreham, UK (below). Like saltmarshes in Australia the hardy plants that live there can have stunning colours as well as providing essential environmental services for us.

Shoreham Beach



Hi All

Today I took Abby to my beach at Shoreham. I explained that the beach was a nature reserve because of the rare vegetated shingle habitat – special plants that grow in the pebbles. They can survive with little water, no soil and survive the strong winds, hot sun and salty sea spray.

Although Steve and the nature reserve team help to look after the plants and wildlife, they were concerned about how global issues such as climate change, sea level rise, increase in storms and other issues might affect this beach. This is why I started my global travels to visit scientists to find out what they know about the ocean and the damage humans are doing to the ocean. 

Off to Dungeness tomorrow to show Abby where some of the beach shingle travels to because of the sea and wave action. Sea defenses stop some the shingle moving so the beach doesn't get washed away

Marine debris collection: TomSea

There are lots of ways to do marine debris collection and we will highlight these from time to time. This clip demonstrates the one that TomSea have developed.
