Marine science class of 2016

The Marine science class of 2016 has started and the students are studying hard for the Cambridge CIE 9693 marine science A level.  The exams are at the end of April so lots of time to enjoy studying on a beautiful beach.

The TRACC classroom has an awesome view and a gently lapping sound as the waves roll up the shore.  For lessons we normally close the shutters so that the distraction of beach and ocean is reduced!

The students are from all over the world, Canadian, Swiss, German, British, Portuguese, Norwegian and Malaysian.  Thats almost a United Nations quorum!

snail zonation 012 (450x800) mar sci jetty snail practical (18) (800x601)Our first lessons have been introducing the topics of oceanography as well as lessons on taxonomy and practicals on zonation and communities.  We believe that getting immersed in the subject is important so we have got in the water by diving, snorkelling and paddling.


Our practicals are all in the environment and we watch ocean documentaries to relax in the evenings.

The students are building bottle and igloo reefs in their spare time and we did stop everything the other day to go and watch a pilot whale as it cruised past.

Recycled Bottle reef restoration of coral reefs

TRACC volunteers have been busy on our bottle reef restoration efforts by making bottle reefs to extend the ribbon reefs on Pom Pom Island. The North Tip ribbon reef is 150m long and the challenge for 2016 is to make it a double row of bottle reefs so that it grows more corals and supports more biodiversity.  The coral growth on the reefs will also help to slow the wave erosion of the beach and improve turtle conservation by ensuring that there is enough sand to lay their eggs.

We were lucky enough in late 2015 to get donations of money to buy cement and a big pile of bottles delivered to the island so we have lots to recycle.  Thank you Coralcare and BGS divers.

The bottle and ribbon reefs built in 2015 are doing very well but we continue to work hard on maintenance of reefs on steep slopes.

recycled bottle reef restorationThe bottle reef restoration start to take shape when the volunteers and gapyear travellers mix wet cement and then position the bottles.  The cement is strong 48h later and the reefs can be moved out into the ocean for a period of soaking to remove toxins.  Eventually we plant corals on the bottle reefs either from fragments grown in the coral nursery or from large branches collected from blast fishing or anchor damage sites.

Reef conservation on steep sloping rubble.

Pom Pom Island has a steep slope from the reef crest to the deep water dropoff at a depth of around 50m.  All this slope has been seriously blasted in the past by bomb fishermen.  All that is left of the original reef are the rubble fragments on a seriously sloping reef.  The reef conservation efforts of TRACC volunteers has increased the biodiversity but the structures are difficult to stabilise.

The TRACC reef conservation for 2015 was generally excellent with amazing successes.  Our coral growth techniques which work well on flat areas of seabed (Bottle & Ribbon reefs) were modified to create step reefs aimed to create small reefs on the steep slopes.  These look great initially but too many of them are unstable and deteriorate rapidly.  While the corals grow and the fish live on the step reefs we create, unfortunately the slope continues to win and changes all the reefs we create.    A beautiful series of steps fixed solidly to the seabed, becomes a tumbled mess after turtles scratch and fish dig.

Stable step reefs are ideal for coral growth.

We have tried spikes into the seabed to hold the structure in place but the rubble flows down from above and covers the steps.  We have tried interlocking the steps and the whole structure moves down the slope as a unit.  We have tried creating curved amphitheatres but after 12 months the structure looks like an ancient roman ruin.

A step reef tumbled by turtles. All of the bottles were embedded in the rubble slope but the scratching of many large turtles has dislodged and strewn many of the bottle reefs.

After much trial and error,  we are gradually refining a coral rubble reef conservation system which seems to be stable.  We are stabilising the rubble with soft coral nets which slows the rubble movement and the turtles do not destroy.  We are then creating Basket reefs which are more stable than the step reefs and have not yet been tumbled by the turtles.  The Basket reefs attract a lot of small fish and are stable enough to remain in place for the long time that it takes to grow hard corals.

Lots of our reef conservation for 2015 techniques work well, hopefully by the end of 2016, we will have also found the best system to stabilise steep rubble slopes.  Wish us luck 🙂

Student projects 2016

Students regularly visit TRACC to collect data for a graduate or masters degree project.  Art or science – if you are passionate about ocean issues then we have intern positions for a wide range of backgrounds. Marine conservation is often about communication and artists, photographers and media students can all become extraordinary advocates for ocean issues.  Each year, we support a few students to become useful interns to do some great science or art.

Photographing rare biodiversity such as this nudibranch (sea slug) requires a commitment to night diving.

Have you got what it takes?  🙂

We have a range of projects in 2016,  from fish surveys to reef restorationcoral planting techniques, Stabilising rubble, optimising growth of coral species, impact of El Nino, climate change impacts on reefs, Turtles,  Sharks, rays, Humphead wrasse, anemone fish reproduction, biodiversity.  Other projects are possible such as the art installation #biggestsharkinborneo.  What are your interests?

Art, media or communication interns please contact us with a formal presentation of ideas.

Generally our science intern requirements are practical in nature:

  • Can it be done in 12 -16 weeks.
  • Does it have a hypothesis?
  • Does it follow scientific method?
  • What is the control variable?
  • How discrete is the experimental variable?
  • Random or structured experimental design?
  • Is the project safe?
  • Etc.  Etc. Etc.
  • Has the student really thought about this?

Most student projects start with a 4 week volunteering experience to gain experience and dive qualifications.  When you have a month of doing underwater work under supervision from our staff then you will move to doing your own things safely with minimal supervision.  We like people doing independent projects to be Rescue diver qualified.  (read why here).

We expect a scientifically viable proposal, background research, strong commitment to the project,  regular written reports, Photos and video, several presentations to others at the camp and a copy of the final report as submitted to your university.  We don’t consider a research project a holiday, it may be fun but there is significant work involved if it is going to be worthwhile.  A scientific internship requires investment by TRACC in your future,  There is a lot of competition.  Are you worth our effort?

To stand out from the crowd:  Don’t simply send us a CV.   Send us a one page (max) project draft based on what you care about, what you can see is happening in the world of marine science or conservation, in our blog or on our facebook & twitter pages.

To learn about the experience – please look at the blog posts from ex students.  See what they did, they may even write about what went wrong.  Contact them on social media and ask for advice.  Be polite and they will help.
