Marine Studies - Year 9 Snorkelling
Our year 9 Marine Scientists have been exploring various snorkel sites in order to learn about the composition of our precious local marine areas.
Below are some extracts from their most current Snorkel Reflections…
- The ecosystems are quite unique to Point Lonsdale beaches as they are on the opposite side of the bay. The different habitats such as Intertidal, subtidal Rocky Reefs and Deep Open Water areas result in a wide diversity of plant life, therefore different marine ecosystems. This means in Point Lonsdale you are getting animals such as Port Jackson Sharks and Abalone, whereas on the other side of the bay you are getting animals like Banjo Sharks and Whiting. The way this beach is positioned in relation to the bay, means it is more exposed to harsh weather like wind, waves etc. This is probably how the unique rock formations came to be.
-The rock pools are large enough to house hundreds of species of marine life. Neptune's Necklace, Algae, Abalone and many other species can be found under the water within these intertidal rocky reefs – the diversity of species here are not found anywhere else in the world due to the various currents running along the east Australian coast, the southern cooler waters and the land formation providing protection around and near the entrance of the bay. Its large kelp forests provide protection for the area's larger fish, and the rock pools give every animal shelter and protection in many different ways.
-During the snorkel this week I focused on equalizing with ease, as it used to be a battle having to hold my nose whilst duck diving. I believe I have improved as it is starting to come more naturally and I am able to spend more time exploring under the surface of the ocean.
