This expedition is based at the marine research site in Akumal. If you are not already dive trained, you can spend your first week completing a PADI Open Water dive training course, before moving onto the Caribbean reef ecology course in your final week. This course consists of lectures and morning and afternoon in-water practicals and trains you in some of the survey techniques used in the marine environment to assess the status of reefs and their associated fish communities. If you are already dive trained or just wanting to snorkel your first week is on the Caribbean reef ecology course and the second would be spent working with different researchers on-site. Projects you will join include monitoring of sea turtle grazing of seagrasses and seagrass biomass in Akumal Bay and investigation of the carbon biomass, health and function of different mangrove systems, including the unique cenote fed mangroves found only in the Yucatan Peninsula.
At the marine site, the research is focussed on assessing the efficacy of the newly formed Akumal marine protected area on the abundance and health of seagrasses and the impact of snorkel tours on the abundance, health and behaviour of sea turtles. Research also aims to monitor the combined impacts of water quality and turtle grazing on the abundance and health of the seagrass ecosystem. In addition, the new protected area provides the opportunity for recovery of the coral reefs, but as natural coral recovery rates are so slow, coral reef restoration projects are extremely important. Assisted fertilisation of coral gametes is used by restoration managers to improve genetic diversity before corals are grown and transplanted to nurseries as coral recruits. Corals spawn only once or twice per year at full moons during the summer and in Akumal and Puerto Morelos these gametes are collected ready for fertilization in the laboratory at UNAM university. Operation Wallacea is assisting this long-term research project in Akumal by mapping the distribution of healthy colonies of hard coral species.
In Mexico it is hot and humid. Temperatures rarely drop below mid 20s even at night. It is unlikely to rain much, but you do get occasional heavy showers during the season.
Fitness level required
Medium in the forest, low on the marine site. There are some reasonably long walks through the forest, terrain varies by camp with some being almost completely flat and others more undulating. On the marine site lower levels of fitness are required (although you will likely be very tired at the end of the day after the in-water sessions).
Facilities in the forest are basic (sleeping in tents or hammocks in a camp site), with a mixture of dry and trench toilets. There are freshwater showers but water conservation is particularly important to bear in mind. There are some limited opportunities to buy snacks at some forest camps and there is no phone signal at any of the sites. On the marine site the facilities are a little less rustic – you sleep in bunk beds in dormitories about 10 minutes drive from the beach. There is good phone signal and the site is well supplied with shops.
