5 Razones para proteger los Océanos

5 Razones para proteger los Océanos

La conservación marina ha sido un tema muy mencionado en redes sociales, pero ¿Porque es importante proteger los Océanos? Sin océanos saludables, nuestra vida en la Tierra sería severamente desafiada, incómoda y quizás imposible. Cómo lo dijo la Dra. Sylvia Earl “No blue, no green”. El océano está conectado profundamente con cada uno de nosotros, necesitamos de él. Aquí les dejo algunas de las miles de razones por las cuales es sumamente importante proteger del Océano:

1) Son los pulmones de la Tierra

más del 50% del oxígeno que respiramos, fue producido por fitoplancton. El fitoplancton son organismos marinos microscópicos capaces de producir oxígeno vía fotosíntesis y se encuentran en la base de la red trófica marina. Son alimento para todo tipo de organismos, desde animales pequeñísimos como el zooplancton, hasta animales gigantescos como la ballena azul.

2) Regulan el clima

 el océano es crucial para mantener el planeta en la temperatura perfecta para la vida, ni muy caliente ni muy frío. La mayor parte de la radiación solar es absorbida por el océano, reteniendo y distribuyendo el calor por todo el planeta. El agua del océano se evapora constantemente, aumentando la temperatura y la humedad del aire para formar la lluvia y las tormentas que luego son transportadas por los vientos a grandes distancias. De hecho, casi toda la lluvia que cae en tierra comienza en el Océano. Las corrientes son igual de importantes ya que ayudan a contrarrestar la distribución desigual de la radiación solar que llega a la superficie de la Tierra. Sin corrientes, las temperaturas regionales serían más extremas.

3) Economía azul

según la ONU, el valor de la economía global basada en los océanos se estima entre 3 y 6 billones de dólares/año y más de 3 mil millones de personas dependen de los océanos para su sustento. Según la CONABIO, entre 2003-2006 los estados costeros contribuyeron al 43% del PIB nacional.

4) Alimento

la FAO indica que 4.3 mil millones de personas dependen del pescado para el 15% de su consumo de proteínas animales, y la cifra es mucho más alta en países en vías de desarrollo. En México durante el 2017 hubo un consumo de 12.6 kg de pescado per capita. No me gusta promover el consumo de mariscos y pescado, pero es evidente que muchos mexicanos dependen de ello. Lo importante es que conozcan de dónde viene lo que comemos, asegurarse que provenga de un método de pesca sustentable y que las especies que estás comiendo no estén vulnerables o en peligro de extinción.  Es un tema muy complejo y por eso, próximamente, le dedicaré un artículo especial.

5) Nos genera felicidad

¿quién no quiere ir a la playa de vacaciones? El mar nos tranquiliza, nos da paz y felicidad. Ya sea para verlo desde lejitos asoleándose y tomando margaritas, o como me gusta a mí, explorando sus profundidades y su vida. Unos segundos después de que nuestra cara toca el agua, el ritmo cardíaco disminuye, provocando una relajación profunda.

¿Cuáles crees que son los fenómenos principales que estamos haciendo los humanos que daña al Océano? ¿Cuáles son las principales consecuencias del daño que provocamos? ¿Qué puedes hacer para ayudar? De eso les platicaré en el artículo de la próxima edición, ¡Manténganse al tanto!

BY: Valentina / 0 COMMENTS / CATEGORIES: Baja, Course, Freediving, Freefall

AIDA 3 Star Course – Freediving Intermediate Course

In this post you will find all the information you need about the Freediving Intermediate Course; the purpose, prerequisites, itinerary, costs, knowledge development and certification requirements.

The AIDA3 Course builds on the skills learnt in the AIDA2 Freediver Course. It is designed to cover the necessary skills and knowledge for a recreational freediver to be able to safely freedive with or without a guideline. The aim of the course is to develop the skills and knowledge necessary to independently plan and participate in freediving activities with similarly experienced freedive buddies. The course is designed to further develop skills from previous levels, develop new skills and a higher knowledge of safety procedures and techniques for freediving such as Free Falling, Frenzel Equalizing, Training Tables, the risks of increasing and decreasing pressure and how to minimize these risks. Students will train these skills in the most common disciplines of freediving; Static Apnea, Dynamic Apnea, Free Immersion and Constant Weight.

Prerequisites

To enroll in the AIDA3 Freediving Intermediate Course, you must:

  • Be 18 years of age or older (16 or 17 years with parent or guardian consent)
  • Have completed the AIDA Medical Form (provided at course start)
  • Have completed the Liability Release (provided at course start)
  • Have completed the AIDA2 Freediver course
    • Or have completed the AIDA2 Crossover Evaluation if crossing over from another freedive agency or having other adequate freediving experience.

Knowledge Development

During the course we will go through theory taught by your instructor in a classroom. You will be given the AIDA3 online manual. We will go through these topics:

  • Physiology
  • Equalization
  • Barotrauma
  • Lungs at Depth
  • Buoyancy
  • Shallow Water Blackout
  • Training Concepts
  • The Mammalian Dive Response (MDR)
  • DCS and Surface Intervals
  • Freediver Code of Conduct

Certification Requirements

  • Pass the theory exam with a score of at least 75%
  • Perform a static breath hold of at least 2 minutes and 45 seconds.
  • Perform a 55m dynamic apnea with bifins (horizontal distance swimming underwater in confined water).
  • Perform a 24m Constant Weight dive (vertical distance in depth in open water).
  • Demonstrate appropriate rescue techniques and safety in dynamic, static and constant weight.
  • Demonstrate a proper technique of the breathing cycle and finning, body position, duckdive, freefall, etc.
  • Design and perform a STA and DYN Training Table.

If you don’t meet the depth requirements you can get certified as AIDA3 Pool Freediver. If you don’t meet any pool and/or depth requirements you can’t get certified at the moment, we would suggest training sessions.

Itinerary and price

Day 1

9am-noon – We’ll meet at the classroom, fill out paperwork and start the theory lesson.

Noon-1:30pm – Lunch break

1:30-6pm – We will meet at the pool to practice static apnea (holding your breath without moving) and dynamic apnea (horizontal distance covered underwater holding your breath). When we finish with the confined water activities we will finish with one more hour of theory.

Day 2

8am-3/4pm –  We will pick you up at the meeting point in La Paz and go on a 45 minute drive through beautiful Baja scenery. When we get to the beach we will do body stretching to relax our muscles and start the freediving-relaxing mode. Once everything is on the boat a local panguero (captain) will take us to the best spot in the area with the best conditions (from 25-45 minute boat ride, depending on the weather). During this boat ride we may see dolphins, pelagic fish and even whales if you’re lucky! When we get to the best spot in the beautiful Island of Cerralvo, we will set the buoy, gear up and start with the open water skills. During this time our panguero will always have the boat nearby with water and snacks.  We usually take a 20-30 minute break halfway through the session to relax and talk a little more easily about how the day is going.  Around 1pm we will take the boat back to shore and be in La Paz around 3 or 4pm.

Day 3

8am-8pm – The same as day 2. After the 30 min break at the middle of the session we give you an option of keep practicing on the line or going to a nearby reef called La Reina and freedive there, sometimes we can see Giant Mantas there!

 

When we go back to La Paz we will take a break so you can eat and relax.  At 6pm, we meet at a coffee shop to do the theory exam and revise it.

Price: $450usd per person

Includes: theory manuals, pool fees, certification, 2 boat fees and basic equipment rental (mask, fins, weight belt, weights and snorkel). Wetsuit and other equipment can be rented separately if needed.

*The location of the depth sessions may change according to the weather and the amount of people taking the course.

We hope to see you underwater! If you have any doubts please contact us at info@freefallacademy.net and we will be happy to assist you.

Freefall in Freediving

BY: Valentina / 0 COMMENTS / CATEGORIES: CNF, Freediving, Freefall

What is freefall in freediving?

The practice of freefall in freediving occurs when a free diver reaches a point of negative buoyancy and stops finning or swimming downward, allowing the force of gravity alone to draw the diver deeper.  

Why do we freefall?

Freefall in Freediving (CNF) - William Trubridge
CNF World Record holder William Trubridge showing us how its done! Freefalling with no fins.

As a free diver descends in water, the volume of air inside of their body (therefore the volume of the body itself) becomes smaller or more compressed thereby changing the buoyancy of their body.  This is explained by Boyle’s Law and Archimedes’ principle respectively.

Every free diver possesses a different degree of buoyancy which is variable to their freediving gear (i.e. wetsuit, weight belt, fins, mask, etc.).  A safe freediving practice is to have a positive buoyancy of at least 10 meters because most of the blackouts happen between 10m and the surface.  This way, if a blackout does occur, the diver will float to the surface, making a rescue more achievable.  We will discuss more safety protocols in a different blog post.  

The freefall is a technique used by almost every professional free diver.  This is because, during the freefall the diver is not required to use physical exertion to gain distance in depth.  This allows the diver to conserve oxygen and energy while decreasing the rate of carbon dioxide production.  The freefall can be likened to a depth static, where the individual can focus her or his consciousness on relaxation and equalization.   

Freefall Technique

Freefall in Freediving with bi-fins
Freefall in freediving with bi-fins (fins are parallel to the line and knees are slightly bent).

That being said, there is a proper technique to the freefall.  When mastered freefall can lead a free diver into a dream-like or zen-like state.  In general, the ideal body position will be as hydrodynamic as possible.  Specifically, the head should be in a neutral position to aide in equalization, neither looking down or up the line. The torso parallel to the line. The arms and hands should be streamlined along the side or front of the body.  Without fins the legs should be straight with pointed feet, or slightly bent legs with relaxed feet.  With fins, the legs should be slightly bent from the hips or knees so that the blade(s) of the fin(s) run parallel with the line (like in the picture).

A good technique will yield a freefall rate of approximately one meter per second (1m/s).

Personal Preference

While in freefall the free diver has the option to close their eyes, this furthers the relaxation and therefore oxygen conservation.  The current CWT (Constant Weight) world record holder Alexey Molchanov while in freefall has said he only opens his eyes slightly every few seconds.   He does this to make sure he has good positioning along the line.  Other divers, such as Alenka Artnik, the CWT Roatan 2017 AIDA World Champion freefalls with her eyes closed the entire time and feels the line with her hand.  There are many slight variations that are a personal preference for each individual free diver.  

In conclusion, the freefall is a very useful and peaceful practice to improve relaxed gains in depth while freediving.  It is personally our favorite part of freediving, hence the name ‘Freefall Academy’. We hope you have learned something from this post.  Please share an experience or thought with us below in the comment section.  Or better yet, come freefall with us in one of our courses here in La Paz. Safe freefalls.

Espiritu Santo Island and Sea Lions

BY: Valentina / 0 COMMENTS / CATEGORIES: Espiritu Santo, Freediving, Sea Lions, Snorkeling

Espiritu Santo Island

A little bit about the habitat of Espiritu Santo Island

Espiritu Santo Island is without a doubt one of the most beautiful places on Earth. It has scenic mountain ranges reaching a maximum altitude of 1200m, extraordinary cliffs made from volcanic stone and pristine white sand beaches.  The amazing water colors, ranging from green turquoise, to deep and transparent blue gives a feeling of tranquility to the soul.

It is a perfect place to experience snorkeling, freediving, scuba diving, hiking, kayaking, camping, stand-up paddle boarding and sailing.

Espiritu Santo Island is apart of the Archipelago of Espiritu Santo, which became a National Park in 2007. Espiritu Santo Island is located in the Gulf of California, North of La Paz, Baja California Sur.  Furthermore, it became an UNESCO World Natural Heritage Site in 2005 along with 243 other islands, islets and coastal areas in the Gulf of California.  These areas contain 39% of the world’s total number of species of marine mammals and a third of the world’s marine cetacean species.

In addition, the island contains many habitats, such as mangroves, sandy bottoms, rocky reefs, estuaries, beautiful isolated beaches and bays. It’s perfect for all kinds of people, from little kids who want to start exploring the underwater world, to experienced divers that would like to see why the Sea of Cortez is called the “aquarium of the world”.

The Flora and Fauna

Espiritu Santo Island has 38 species of plants and animals that are unique (or endemic) in the whole World.   The juancito, the babisuri, the black hare and the sandy snake are examples. Furthermore, there are 200 species of plants and more than 70 species of animals (not counting the ones underwater).

As you submerge before the surface you can find at least 15 species of marine mammals, including dolphins, whales and the famous colony of sea lions.  In addition, you can find more than 50 species of aquatic birds gracing the waters, airways and cliffs.

Sea Lions of Espiritu Santo Island

The Sea Lions that live in the islets called “Los Islotes” or “La Lobera” are a species scientifically called Zalophus californianus.

A big group of Sea Lions at “La Lobera”

As well as other marine mammals, sea lions are very curious. This attitude has to do with exploration and playing. The young ones are especially playful; they might even play with your fins or other “weird” equipment. Think about a cute little puppy, then put it underwater, let it evolve and you will have a beautiful playful sea lion.

These beautiful creatures are on the island all year around. Los Islotes contain about 500 sea lions every year. The reproduction season initiates with the birth of the pups at the end of May.  Continuing with the breast-feeding and mating time around June, July and August.

Don’t miss the opportunity to swim or dive with these beautiful animals in Espiritu Santo Island. Check out our tours here.
