Today’s Science Blast

Digging a hole underwater, sounds simple enough right?

Well today we wanted to give it a go, in preparation for the sinking of our structures later on this month. Our first structure has four bases, and each needs to be buried a metre under the sandy bed to ensure that all of our hard work doesn't get swept away in a storm.

An extra tank, some plastic tubing, and a first stage was all we needed to drill a hole in the seabed. We loaded ourselves and our kit onto the dive boat, located our reef, and dropped down.
Now, we had expected the dive to be somewhat ‘trial and error’, but what we hadn't planned for was the large quantity of dead stag coral in the sediment. Our potential site for the structure is a sandy bed sheltered by a reef either side. We chose the area because of the proximity to natural Acropora populations, which are the healthiest growing in the area, as well as the water quality, temperature and salinity. Today our choice of site was compounded by the discovery of lots of stag coral remnants in the sand and deeper sediment at our site proving that historically a large amount of Acropora has been growing here.

We began the digging by placing ourselves firmly in the seabed and positioning the end of the tube into the sand. The equipment works by pushing pressurised air from the tank down through the first stage and tubing into the seabed. The pressurised air displaces the sand, making a hole quickly and with minimum disturbance, just a little sand in the face to deal with.

As we pushed down it became clear that there was something in the way. In the small hole we had created, just a couple of feet under the sandy bottom, there were hundreds of fragments of dead staghorn coral. Some had disintegrated down into small shards of brittle coral, showing that they had been there some time, whilst larger less degraded parts demonstrated that more recently there has been living Acropora growing in this spot.

The discovery of Acropora up to 3 foot under the sand supports our hypothesis that Acropora historically grows in this particular area, and indicates that our coral nursery will be well placed here. There were so many fragments that there can be no doubt that in the past Acropora was thriving here.


Happy with our discovery, we finished up taking some more water samples and measurements of living staghorn, and ascended to the surface, enthused with our unexpected find.

As one of my first science dives here at Expedition Akumal, this was pretty exceptional. We found even more evidence to support the project, got some excellent data, and tested out how we will sink the base of the first structure.

Coral Monitoring, Fragmentation, and Aquaculture Initiatives

Coral Monitoring, Fragmentation, and Aquaculture Initiatives

I assume everyone knows the history of aquaculture when it comes to growing coral.  I will say the process hasn’t changed much from when it was developed by civilian aquarium enthusiasts.  What has changed is the necessity to grow coral in semi-captive environments and transplant it back onto our larger reef systems.

Currently, in Akumal, we have been collecting photographs and data of our Acropora species and some of our Diploria.

Obviously we have some problems with our water quality in general up and down the peninsula.

I’ll begin by explaining the diagnostic testing I am doing, and my reason for doing these standard tests.

I’m currently testing
  • Ammonia levels – which are varying between little more than 0.00 PPM up to .50 PPM on the reef
  • Nitrates are being tested at stands of living, diseased, dead, and thriving colonies of Acropora due to our high Algae growth on the reef and the main bay. 
  • pH is being tested to assess poor coral growth.  This gives us an indication of the variance locally.  We can compare this to what are considered normal ranges for the species we are losing and targeting for our coral nurseries.
  • I am testing pH and Nitrates at stands of diseased or dying Acropora
  • Each stand of Acropora is then measured in width and height – to determine age, size, and area of disease and in most instances photographed.
  • We take the water temperature
  • Currently, we record the depth and location of the stands we are studying
  • Specific Gravity is also recorded to assess salinity: especially with so many fresh water cracks that feed into our ocean and bays locally.

I am currently not testing: Alkalinity:KH, Phosphates, or Calcium around living and dead stands. 

Currently I am concentrating on 4 areas. These are areas in the NE and SE portions of Akumal Bay, Church reef, and Yal Ku Canyon.  These areas tell the story of the reef’s decline. However, I think these locations offer us a good deal of hope, and possibly a road map to revitalizing the reefs of Akumal and the Riviera Maya.

Coral fragmentation and success around the globe!!

Below are some great examples via actual pictures of what our goals are and the many different techniques being employed around the world to mitigate the damage inflicted on our oceanic rainforests! 


Coral Nurseries Around the World

Expedition Akumal: Coral Restoration Project


Expedition Akumal - Coral Restoration Project

When asked to give a brief summary of the 'Expedition Akumal Coral Project' - I sum it up this way.


The Expedition Akumal Coral Project aims to revive and restore our local reefs and by proxy the Meso-American reef - the 2nd largest barrier reef in the world- via coral fragmentation nurseries  - these nurseries will also serve as nurseries for our reef fish which will in turn help replenish or bolster our fish stocks.  We are attempting to identify strains of our reef building corals - primarily staghorn and elkhorn corals that may be more resilient to temperature and disease - or simply more resilient in general.  We can grow these more resilient strains and transplant them back to their rightful place on the larger reef.  


The time commitment currently for each 4 person 'Science Diver' group, is between 7-14 days.  Obviously, we'd prefer if people could stay longer.  Our first group of 'Science Divers' were here 14 days and did about 22 scientific data gathering dives.  That however, is a great amount of diving for an average person on vacation so everything is tailored to the individual. 

As far as the work, it's work, absolutely beautiful work.  It is also vital and critical work here in Mexico and around the world in tropical areas. 
If you want to stay and work a month we'd love to have that also. 
Essentially, the original and first boutique hotel in Akumal.  Hotel Akumal Caribe, has created a 'Science Diver' Package in conjunction with CEA and Akumal Dive Center.  This allows you to work and vacation at the same time.  There are morning breakfast briefings and evening dinner debriefings.  At the end of your stay you may write a paper on the work that you did for our data repository.  This allows each group to build upon the work of the previous groups.  Your dives are video recorded and added to a data repository for a documentary and for your personal use.  You will be taking photos, mapping, testing Specific Gravity, PH, Nitrites, Nitrates, Temp, plankton percentage, Ammonia, and reef population studies.

You would also be locating and using GPS to map healthy and diseased or dying stands of Acropora.  You may also participate in a few Lionfish hunts, should you be so inclined.  We hunt normally about 2 days a week.

We have begun to to think of this as an all inclusive 'science trip', you may have a Lol Ha meal plan, unlimited 'Science' diving,  excellent training, a wonderful, beautiful hotel on Akumal Bay, and you become part of the project which is in fact our only solution - True Sustainable Tourism!  We ALREADY have members booking for next year to build on the work we started this year.  I'm very excited about the project here in Akumal and hope that the public really becomes a part of the solution!
  1. If you'd like to become a science diver we'd prefer Advanced OW Diver Certifications with a Peak Performance Buoyancy Class.   If Open Water certified - you must take a peak performance buoyancy class here or there.  We are working with truly 'threatened' species and to do this work requires permits from the government.
  2. Can I help if I don't Scuba Dive?   Answer:  Yes!!! Message us at Expedition Akumal on FB.
  3. Donations are tax deductible and I'll add the exact information here in the next few days!
  4. Throwing this out there: We are desperately in need of a new underwater GPS device.  If anyone has one they are not using that can be donated - Please contact me!
  5. Additionally, please indicate whether you are interested in the 14 day package or 7 day 'Science Diver' package we are currently offering.  So I may get you the correct package info and breakdown.
Many Thanks and I hope to work with you soon.

Adventure Akumal Science Diver Package: Phase 1

Last year I came to Akumal for the first time. An old high school friend of mine was working toward his master diver certification, and he invited his diver friends from around the US to come down to Mexico and dive with him. Not only was I in need of a vacation; it had been two years since I had last sought the solace that nothing but the ocean can give me.

The first day and even well into the second, I could not believe I was really here, walking along sandy paths and coral walkways with the warm ocean breeze. Once I plunged into the water backwards off the edge of the dive boat and could hear nothing but the sound of my body inhaling and exhaling did I finally arrive fully in Akumal. I was underwater, drifting slowly downward, willing myself closer to the coral seascape below. At peace and filled with wonder. Surrounded by delicate fans of purple lace, velvet pillows in green and blue, iridescent creatures dressed in the deepest and richest of hues. My happy place. At last.

During that seven-day vacation, I dove Motorcycle Reef, Las Esponjas, Las Redes, and La Tortuga, each with its own signature seascape, each one magical in its own right. I felt alive and returned to my normal life on land with more energy than I had felt in a long time. Recharged. Renewed. Reinvigorated.

So nine months later when my friend posted another call for divers to join him in Akumal saying that for a special project he needed three or four science divers over the next few months for five to seven days, I responded immediately, instinctively. I may have landed a career in higher education administration, but I have not been able to shake my dream of becoming a master diver and working to protect and conserve coral reefs, a dream that began fifteen years ago when, as a newly certified open water diver, I discovered the majestic Great Barrier Reef.

He explained that the diving would involve mapping and gridding the bay, conducting population studies, and analyzing the marine environment for the potential to regrow and repopulate the reef, which made perfect sense to me. When I had last seen him, he had shared with me his ideas about civilian divers augmenting the workforce of research teams already collecting reef data. More people gathering more information would help advance the evaluation of the reef’s health and the sharing of that information with communities whose livelihood depends on Akumal Bay and their ability to attract tourists. He explained furthermore that the dives would focus on what James Byrne, marine biologist for The Nature Conservancy, aptly calls staghorn and elkhorn coral, “the girders and I-beams of reefs that provide critical fish habitat”[i].

It is now Day 8 of my working vacation, and this experience has been more than I could have ever anticipated. The work of measuring salinity, pH and ammonia levels, noting the depth, water temperature, and dimensions of both healthy and unhealthy stands of staghorn coral is challenging. I have never cared so much about my trim, about my ability to maintain neutral buoyancy underwater so that I can take a clear picture of my fellow science divers assessing the marine environment.

I have seen and documented the underwater tourist spots, coral abundant with life.



I have also seen and documented the places where tourists don’t go: the underwater wastelands. The devastation is appalling. A field of soldiers who’ve fallen in battle comes to mind, an unnatural and forsaken graveyard.



I have felt discouraged, hopeless: coral reefs around the world are dying. The Great Barrier Reef has shrunk by fifty percent in the past three decades[ii]. But I also feel empowered. My two-week experience here is a trial run for a new dive package, Adventure Akumal Science Diver Package. Using the lessons learned from this pilot and with support from the community, certified divers living in or vacationing at Akumal will be able to apply their skills and their passion for the ocean directly toward helping rebuild the reef. Like me they will learn many important things:
  • Fifty percent of the Mesoamerican Barrier Reef has died in the last twenty years.
  • Staghorn and elkhorn coral, both listed as threatened under the Endangered Species Act[iii], can be raised like plants in a nursery.
  • Reversing or mitigating the stress caused by tourism is possible through action, education, and awareness.
  • Projects like this—Reefscapers in the Maldives[iv] is a great example—have been successful all over the world, replenishing the coral that serve as protective havens for baby fish making it possible for fish to thrive and repopulate the ecosystem at healthy, balanced levels.
  • Collecting data, a first step toward rehabilitating the reef ecosystem as a whole, can be done at a faster rate with civilian divers augmenting the work being conducted by coral scientists and researchers.
We hope to identify staghorn and elkhorn coral that are resilient and managing to survive in the conditions that have been created by increasing numbers of people using the bay as a source for food, recreation, and knowledge—it is after all equal parts farm, playground, and classroom. The Akumal Coral Transplanting Project, beginning with reef building coral, is working to rehabilitate the reef ecosystem as a whole.

Anyone can participate in the Akumal Coral Transplanting Project and give back to this special place that provides sustenance, solace, and scholarship. Camera footage from the pilot dive experience will be shown at a fundraising event on Superbowl Sunday at Lol-Ha. Proceeds will go towards the Akumal Transplanting Project, an initiative of Hotel Akumal Caribe with Centro Ecologico Akumal.
