The tropical Indo-Pacific warm pool (IPWP) is a major heat reservoir that influences global atmospheric circulation. The IPWP affects temperatures in the Wakatobi on an annual basis causing large temperature changes. Reconstructions from Foraminefera cores covering a span of 2000 years suggest that the temperatures at times over those 2000 years may have been even higher than at present. This might be one of the reasons why corals in the Wakatobi appear to be more resilient than in the Great Barrier Reef with much less bleaching occurring. This topic makes use of Hasanuddin University facilities to examine temperature tolerances of reef fish species and more thermal dynamics studies have been published from Hoga Island than anywhere else in the Indo-Pacific. This topic could include: determination of critical thermal limits of field acclimated fishes, acclimation dynamics of fish exposed to different temperature treatments, and thermal acclamatory capacity and plasticity. All studies will involve animal husbandry and feeding, field collections, and laboratory-based experiments but will also involve field work and ecological observations of the study organisms.
*Does not require data to be collected by diving, although you could still dive in your spare time.

Extended Dissertation Summary

If you would like to do a dissertation or thesis with us but your university hasn’t started dissertation planning or the project selection process, that’s no problem. You can cancel your expedition with zero cancellation charges up until the 15th of April of if you provide documentation from your university saying that they won’t support completing a dissertation project with us.

Indonesia - Wallacea Marine Research Objectives

There is a triangle of reefs in Eastern Indonesia that have the highest diversity of hard coral genera, the proxy commonly used to assess overall diversity of coral reefs, anywhere in the world. Both the marine stations being used by the Opwall teams are in the centre of this triangle. The South Buton Marine Centre has established a series of standard monitoring sites on reefs south of Bau Bau and around the surrounding small islands, with the objective being to use the data to develop plans for conserving these reefs. The Hoga Island Marine Station is located in the heart of the Wakatobi Marine National Park. Over the last 20 years, a series of scientists have been based at this site during the Opwall survey seasons and as a result, this is now the most published site in the Coral Triangle. For the last 15 years a series of constant monitoring sites around Hoga and eastern Kaledupa have been monitored for macroinvertebrates, fish communities, coral cover and community structure. The 2020 season will complete this monitoring plus some additional projects.

  • Develop an independent research project and write a formal proposal
  • Dive or snorkel on a range of reefs around Hoga island
  • Complete a week-long training course on Indo-Pacific coral reef ecology
  • Learn common field laboratory techniques
  • Collect data from behavioural observations under controlled conditions
  • Learn how to organise and analyse large data sets
  • Opwall fee
  • Cost of international flights into and out of Jakarta
  • Cost of internal travel to and from the start and end point of the expedition, plus any hotels you might require. This costs around £300 or $375 on average. Extra nights’ accommodation can be quoted
  • Visa costs of $35 for a VOA (31-60 days, with extension), £50 for a social visa (60+ days, with extension) plus £45(VOA) or £60 (Social Visa) for the extension. Please get in touch with someone from Opwall for more detailed advice.
  • Dive equipment rental – £60 or $90 per week for a full dive kit. If you only wish to snorkel and want to hire snorkel equipment, the cost is £30 or $45 per week. Please note that wetsuits cannot be provided – you should bring your own.
  • Park entrance fees – £20 or $29
  • PADI manual and PIC card (if you are completing your Open Water qualification) – £69 or $87 approx.
  • Vaccinations and prophylactic medicines – cost can vary depending on your healthcare provider.
  • Spending money for snacks/drinks/laundry – Indonesian rupiah only.
  • All prices in GBP or USD unless specified

Climate

At the marine sites during the day, the weather is normally sunny and warm (around 30 degrees Celsius), and the night temperatures drop to around 20-25 degrees Celsius. Being on the coast means there is often a pleasant breeze so it does not always feel this hot. It rains rarely, but when it does it tends to be very heavy for short periods of time.

Fitness level required

Low-Moderate. Some fitness is required for in water activities, but conditions are relatively easy.

Creature comforts

The Hoga Island Marine Station is an established facility that lies within the Wakatobi Marine Park of eastern Indonesia. The station was rebuilt in 2016 and supports a dive centre, lecture theatre, wet-lab as well as a large dining room and kitchen facility. Simple huts owned by members of the local fishing community surround the station and serve as guest accommodation. The island supports reliable phone signal that allows limited internet access.
