2026 Dates

2 weeks: 2 weeks marine only – 17 July – 30 July 2026

This is a diving and marine research centre on the island of Nosy Be. You will start with some training, beginning with the opportunity to complete an SSI Open Water dive training course if you would like to learn to SCUBA dive and are not already qualified. In your second week you will complete our compulsory Indian Ocean reef ecology and survey techniques course, which consists of two lectures and two in-water practicals each day (either by diving or snorkelling). If you are already a qualified diver when you arrive to site, or would like to snorkel whilst on expedition, in your first week you will complete the compulsory reef ecology course before journey our research team in your second week. In your second week you will assist our researchers with data collection and analysis, helping with the quantification of the fish communities from stereo-video surveys and examining the benthic composition and health of our reefs. For an extra charge there is also the option of completing additional SSI dive training in your spare time.

Madagascar Nosy Be Research Objectives

Nosy Be is the premier dive destination on Madagascar, but there are few data on the coral reef communities that support this industry. Opwall teams will be gathering baseline data on these reefs, including data on fish community structure from stereo-video surveys, coral cover from video transects and 3D modelling.

  • Dive or snorkel on a range of Indo-Pacific coral reefs
  • Complete a week-long training course on Indian Ocean reef ecology and survey techniques
  • Learn survey methods to sample the coral, invertebrate and fish communities
  • Attend our marine research lecture series
  • Collect ecological survey data on coral reef health and diversity
  • Learn some basic Malagasy words and phrases
  • Opwall fee.
  • Cost of international flights into and out of Nosy Be (NOS).
  • Cost of internal travel to and from the start and end point of the expedition, plus any hotels you might require. The standard package costs around £42.

Climate

In Madagascar it is the dry season so it is hot during the day (temperatures between 25 and 30degrees Celsius) with extremely little chance of rain. During the evenings the temperature can drop slightly but still remains consistently warm.

Fitness level required

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

Creature comforts

Facilities at the marine site are a little less rustic with dorm style accommodation and running water for showers and flushing toilets. The marine site does get some phone signal but it can be unreliable unless you have a local SIM card or eSIM.
