Age 20+

The Dulce Gulf, meaning the Sweet Gulf is located off the Osa peninsula, one of 25 biodiversity hotspots worldwide. In fact, the Dulce Gulf is one of only four tropical fjords in existence. Yet very little is known about this place and its inhabitants, which include macaws, monkeys, dolphins, whales and of course sea turtles. This astoundingly beautiful area is the home of this important In-water Sea Turtle Conservation programme. The international NGO running this programme has been working for over two decades together with scientists, conservationists and educators to promote sustainable sea turtle projects in the wider Caribbean region.

The programme focuses on carrying out in-water studies of the Hawksbill and Eastern Pacific Green Turtles. Because of the unique biological characteristics of sea turtles, the marine conservation efforts surrounding them is very complex, challenging to predict and requires a long-term commitment. The goal of this programme is to protect and help the turtles while at the same time educating and involving the local community, which in turn will generate an alternative and sustainable source of income for local families.

Sea turtles spend a large part of their long lives migrating between nesting and foraging areas. These foraging areas often include both young and adult turtles, as they can sometimes also be habitats for nesting. As a result, the quality of these areas is of critical importance. Despite this, very little is in fact known about the habitats and their use, since most conservation efforts are focused solely on nesting beaches. The in-water studies consist of entering feeding habitat used by sea turtles in different life stages to collect data about population structure, genetic origin, health status and in-water habitat use. This data is used to assess the types of threats to which sea turtles are exposed to in the area.

This programme also runs a rescue and rehabilitation centre, as well as a mangrove reforestation effort. Studies are also carried out on the health of the off-shore sea grass bed, which is an important feeding habitat for many species, turtles included.

In-Water Sea Turtle Monitoring

It is important to remember that sea turtles always come first. This may mean working long, hard hours under hot and humid conditions; but in the end, it is worth it!

In-water monitoring surveys will be conducted at least twice a week (weather permitting) for about 6 hours at a time. Before setting out, the boat has to be prepared and you will be needed to help make sure all the necessary equipment is ready and on board. Once a sea turtle is caught, you will help take biometric data, tag and collect tissue and blood samples if needed. Depending on the condition of the turtle it will either be taken back to the rescue centre or released immediately back into the water.

Rescue Centre

The rescue centre was built to treat injured or sick turtles encountered during the in-water monitoring work or nearby beaches. When a sick or injured turtle is admitted to the centre, you will assist staff in evaluating the patient, recording data and helping stabilize the turtle. Other general duties in the centre include preparing food and feeding the turtles, changing water and cleaning holding tanks as well maintaining the centre tidy and clean at all times.

Mangrove Reforestation

Mangroves play a very important role in the coastal ecosystems on the Pacific coast of Costa Rica and their rapid decline is a major cause of concern, not only for the sea turtles, but for the many other species they benefit as well.
Duties involved with this work include:

  • Looking for seeds
  • Gathering mud for plants and seedlings
  • Sowing seeds in the plant nursery
  • Planting propagules in the designated reforestation areas
  • Maintaining plant nursery

Sea Grass Monitoring

Sea grass meadows are a crucial reason as to why we find sea turtles in the area and they are one of the most productive ecosystems on earth.  As a part of the programme you will help to monitor the health status of these beds. Monitoring activities carried out will depend on local conditions.
During your time off from the conservation work, you can enjoy the beautiful surroundings of the Osa peninsula, a biodiversity hotspot in Costa Rica. Due to the absence of strong currents and waves, the water is perfect for swimming and snorkeling. The nearest town is 30 minutes away from the programme, where you will find a greater variety of amenities.
