A Christmas reef clean up – making a difference

Here at Quo Vadis Dive Resort, we think that being a diver carries more responsibilities than just diving and looking at fish. As soon as you get certified as a diver, you don’t just learn about safe diving practices, but your instructor should also have taught you about the importance of being a responsible diver in regards to the environment.

The surface of the world as we know it right now consists of 71% water, and the oceans hold about 96.5% of all Earth’s water. Rain forests are responsible for roughly one-third of the Earth’s oxygen, but most of the oxygen in the atmosphere is produced by marine plants. The production of oxygen in the ocean is created by plants (phytoplankton, kelp and algal plankton) that live in the ocean. Same as plants on land, the marine plants produce oxygen as a byproduct of photosynthesis. This process converts carbon dioxide and sunlight into sugars that the organisms use for energy. One specific type of phytoplankton (Prochlorococcus) releases vast amounts of oxygen into the Earth’s atmosphere. It is the most abundant photosynthetic organism on our planet.

Phytoplankton creates the base of the marine food chain. The health of all organisms in the ocean is directly related to the health of phytoplankton.

So how can we help to save our oxygen?

Save the phytoplankton!

How do we do this?

Decrease you impact on pollution by using less energy (go to work via public transportation or your old school bicycle), help protect habitats on land and in the ocean (donate to organizations that can make a difference or volunteer on land or in the ocean by doing clean ups), encourage others to stop over-harvesting ocean wildlife (talk about the negative effects in the ocean of consuming predatory fish and also the consistency of mercury in bigger predatory fish and personal health risks that are related to the consumption of a lot of fish).

Since you see what is going on as a snorkeler or a diver below the surface, you can personally help out by not only telling how amazing the marine life is, but also the changes that you might have seen already over the last few decades. Your pictures and stories can help others care as much as you about the ocean and their habitants, and hopefully through your stories you can educate others about the importance of protecting our oceans. You are a diver, snorkeler, and with it you are the most important ambassadors to help protect our oceans and oxygen.

Want to make a difference soon?

Come and join us on our Christmas reef clean up and by diving against debris we will donate 500 Php of the money you paid for the dive to PROJECT AWARE to help save our oceans. Find us on Facebook or simply e-mail and sign up! See you on the 22nd of December!

What exactly is coral??

Coral reefs are formed by groups of marine invertebrates that live together.

Each individual is known as a polyp. Corals feed by sticking out their tentacles into the water and catching drifting plankton and when they’re inactive, corals protect themselves by withdrawing their tentacles.

Large coral colonies you see are formed over hundreds and even thousands of years as polyp growth rates are extremely slow – up to 1cm per year.

When a polyp dies naturally a new polyp will form over the top. Repeated over many years, this process eventually results in the massive coral formations you will see today. As sea levels rise and fall over geological time the ‘active’ area of the reef changes over time. The white sandy beaches you see around these islands are produced by dead coral broken up over time in to smaller particles of calcium carbonate.

How Does Coral Feed?

Only a fraction of a coral’s food is from what is caught by the tentacles.

Coral’s main food source comes from a symbiotic relationship (mutually beneficial partnership) with photosynthesising algae collectively known as zooxanthellae.

The algae provides a coral with it’s colour. Without any algae, all shallow water coral would be white. The relationship between coral and algae is incredibly efficient, providing the following benefits:

Benefits to coral

Benefits to zooxanthellae

supplied with up to 90% of energy requirements as well as oxygen and aids with waste removal

safe environment to grow

provided with glucose, glycerol and amino acids for production of sugars, fats and most importantly calcium carbonate for reef construction

provided with compounds required for photosynthesis

5 awesome facts about the seahorse

1. Did you know that the Latin family name of the sea horse, hippocampus, translates to horse seamonster? They sure don’t look very scary to me. Their size are ranging from tiny 1.5 cm up to 35 cm. 2.

2. They don’t have any stomach and because of the missing stomach these horses needs to eat all the time. To be exact they need to find at least 3000 tiny shrimps every day or they would die of starvation.

3. The male seahorse really takes his daddy role very serious. In this relationship the male are the one to carry all eggs in his pouch. Of all the eggs only one of thousand survives to an adult size. Some studies shows that they are extremely faithful to each other. Once they find a sea horse partner in their taste they stick with each other for the rest of their life. How romantic!

4. To great exercise can kill this little creatures so mostly they are sitting on the same coral relaxing and eating. Except to gain too much weight the only thing this guys need to worry about is the hungry crabs. If the dwarf sea horse needs to run from the crab he faces a problem, since his horse powers only can create a top speed of 1.5 meter per hour…

5. The seahorse are endangered by over fishing and habitat destruction. The Chinese medicine market has a huge responsibility since they convinced the chines people that seahorses cure impotence, wheezing and pain. Which has non-scientific proof. 20 million seahorses are estimated to been taken from the sea by this reason every year.

The fishing of the endangered seahorse has been controlled by CITES since 2004. CITES is a Convention on International Trade in Endangered Species of Wild Fauna and Flora. Sadly enough Norway, Japan, South Korea and Indonesia didn’t sign the law. Support CITES and other ocean fighters that supports our ocean with knowledge among the local people.
