PADI Divemaster and Marine Conservation Apprenticeship in Mexico

‘If only every student could do this. It changes your life in all the right ways,’ says Chris Heritage, parent of Luke Heritage, one of our teen volunteers who has participated on two GVI programs, one in Costa Rica and another in South Africa.

We are a parent-run organisation that is incredibly serious about health and safety, and increasing the impact, as well as the long-term career benefits of our programs. Our programs help young people develop the skills to select a career path that is personally fulfilling, and live a life aligned to the well-being of our planet and the global community.

GVI is a proud member of the Gap Year Association.

Ken and Linda Jeffrey, whose son Sam volunteered with GVI in Thailand, talk about how the experience affected Sam. He also went on to volunteer with GVI again in South Africa. ‘I know it sounds like a cliche but in a sense, he did go away as a boy and he came back as a young man. Both of us could recommend GVI without any hesitation to any other parent thinking about exploring an opportunity for their children to explore the world and to see different parts of it.’

All of our programs have short-, mid- and long-term objectives that align with the United Nations Sustainable Development Goals (UN SDGs). This enables us to report on our collaborative impact across the world in a streamlined manner, measuring which UN SDGs we are making a substantial contribution to. Furthermore, this will help our local partners and communities measure and visualise their contribution to the UN SDGs.

Prior to your arrival on base, you will be educated about the UN SDGs. Then once you arrive on base, you’ll learn about the specific goals we have in this particular location, our various objectives, and also clarification of how your personal, shorter-term involvement contributes to these.

Our aim is to educate you on local and global issues, so that you continue to be an active global citizen after your program, helping to fulfil our mission of building a global network of people united by their passion to make a difference.

Puerto Morelos is the oldest port city in the Mexican Caribbean. Used as a port since the Mayan empire, its history as a modern port dates back to 1898. It was built to enable the exportation of gum from gum trees and wood from dye trees. Together with fishing, these were the main productive activities in the area.

There is a unique diversity of ecosystems – including low evergreen and swamp jungles, savannahs, coastal dunes, mangroves, cenotes, beaches, marine grass and coral reefs. The reef of Puerto Morelos is part of the Mesoamerican Barrier Reef System – home to thousands of marine species.

Today, Puerto Morelos is part of the 120-kilometre-long tourist corridor located between Cancun and Tulum. Tourism is the main economic activity of Puerto Morelos and continues to grow due to the development of large hotels and holiday accommodation along its coast. Local tour operators offer scuba-diving, snorkelling and free-diving tours in the Caribbean Sea, as well as reef lagoon, sportfishing tours, and tours to (and diving in) cenotes close to the town.

Fishing is the second most common commercial activity after tourism. Small skiffs are used to collect lobster and many species of commercial Caribbean fish. Local fishing organisations are aware that unsustainable fishing leads to the destruction of the reef, loss of fishing resources, and harm to ecotourism activities. GVI assists our partners in Puerto Morelos by collecting and collating data which helps decision-makers in coastal zone management. 

Fish and coral surveys

We have several monitoring sites that we survey each year. The data we gather helps us determine the abundance and size of the fish, and understand the changes in the fish community dynamics. The information on coral, and other benthic organisms like sponges and macro algae is used to understand the reef’s coral coverage and overall health. The surveys are simpler for 4-week short-term interns as we aim to gather high-quality data by focusing the learning on fish species while touching on other topics such as coral species. The aim of this is to collect biomass data and information on coral illnesses and bleaching.

We also assist our partners in a coral reef restoration project. Through cloning (coral fragmentation) and assisted fertilisation of coral gametes, we assist in incrementing the biomass and genetic diversity of the hard coral population. We collaborate on coral nursery maintenance (inland and in water). And finally, we assist with transplanting coral colonies back into the reef to regenerate degraded sections of the reef in the ocean.

The Caribbean King Crab project rears juveniles to sufficient sizes and numbers to be used during coral restoration work, which increases the survival of transplanted fragments or recruits by actively counteracting macroalgae proliferation. You can play a part in the regeneration of degraded sections of the reef and rebuilding the ecosystem.

Turtle monitoring

The National Park of Puerto Morelos is abundant in seagrass, one of the favourite meals of green sea turtles. GVI participants assist with monitoring sea turtle populations by taking pictures of them while snorkelling and diving. This helps with identifying new and returning sea turtles. Sea turtle nesting season is from May to October.

Invasive lionfish monitoring and education

Lionfish are an invasive species in the Mexican Caribbean. We carry out lionfish data collection during our dive activities – registering size, quantities, location and depth, as well as taking photos of the specimens. We turn this information over to local authorities who keep track of the lionfish population dynamics. At times they request our assistance in removing this invasive species from the sites.

Incidental sightings of megafauna

Every time we dive, we look for megafauna species such as sharks, dolphins, manatees, sea turtles, eels and rays. We input sightings of these species into our database. The presence of these species can be an indicator of the health of the reef and general biodiversity.

Plastic pollution cleanup

We have weekly beach cleanups where we collect the rubbish that washes up on our beach. We classify it and count or weigh it into different categories, depending on their source. This information is recorded and sent to our partners in Ocean Conservancy. After adding it to their worldwide data bank, they analyse the information – looking for trends on sites and classification of rubbish.

Environmental education

By joining a GVI marine conservation program in Mexico, you’ll get involved in vital project work that directly impacts our partner organisations’ ability to promote their initiatives and carry out their mandate. This includes things like the creation of marine reserves, zonation schemes, and management policies. In turn, you are helping to protect Mexico’s precious marine life and the ecosystem.

You will be able to work closely with our local partners – collecting and collating data that is used to aid decision-makers in the coastal zone and resource management in Mexico.

You’ll also assist the community by conducting environmental education programs. Once a fishing village, the town of Puerto Morelos is now part of one of the largest marine parks in Mexico. Fish is still an important food source in the community, and fishing provides a daily source of income. Sustainable fishing methods and other means of protecting the natural environment are vital to maintaining the marine abundance that makes fishing and international tourism profitable. We work to support the local community’s efforts to learn about and protect their marine resources and the health of the reef off the coast of Puerto Morelos.

These initiatives allow us to support the conservation work, the community, and our local partners. They also address two of the United Nations Sustainable Development Goals (UN SDGs), namely Goal 4: Quality Education and Goal 14: Life Below Water.

Below is a list of core ethics and best practices we believe are essential to the operation of high quality, ethical volunteer and sustainable development programs. We believe that all responsible volunteer and sustainable development operations should focus upon these principles. If you are considering volunteering, these are some of the key considerations you should question, to ensure that your time and money contributes towards positive change.

We want to constantly develop our own understanding of ethical best practice. In so doing, we aim to provide an exemplary industry standard for other education institutions, international development organisations, and social enterprises. Our Badge of Ethics stands for the drive to always do good, better. Find out more, click on the Badge below.
