Playing with the Halocline

A cave dive playing in the halocline, meeting with remipedes

This cave is just amazing, dark with a very well defined halocline. Recommended to dive with Nitrox and with stage side mount or stage back mount configuration as it is fairly deep and you will want to stay as long as posible.

Halocline: from Greek hals, halo- ‘salt’ and klinein ‘to slope’

The halocline is the area within a body of water that marks a drastic change in salinity.

Haloclines are common in underwater caves near the ocean. The fresh water, less dense, forms a layer above the salt water from the ocean. For cave divers, it causes the optical illusion of air space in caverns. Passing through stirs up the layers and blurs the vision.

The halocline itself is responsible for the formation of the cave systems. The mixing of the saltwater and freshwater results in reactive brackish water that dissolves the limestone, eroding the rock and enlarging a cave’s passageways.

Because different water densities meet at the halocline and both organic and inorganic particulates accumulate there, it is chemically speaking an intriguing place.

Deco stop at Cenote the Pit, Dos Ojos

Some parts of the world offer spectacular dives at depths greater than 39 meters / 130 feet, but there is no access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques to efficiently use compressed air as a bottom gas to a maximum depth of 55 meters / 180 feet.

Pozo Azul Exploration Project

Pozo Azul exploration: A fascinating cave exploration project!

Pozo Azul is currently the longest cave dive penetration in the world,
And more than 9.4km of diving accumulated over 5 sumps are required to reach the furthest point from the single entrance.

Located in the village of Covanera, Burgos, Spain, El Pozo Azul is probably one of the most challenging cave exploration project. Already 5 sumps (maximum depth 71m) had been explored. And in 2015 J. Mallinson pushed the exploration solo and discovered a 6th sump and spent a total of 60 hours inside the cave.

In 2001, Jason Mallinson first visited the site with Rupert Skorupka. At that time the known part of the cave was a 1st 700 m sump, then a dry tunnel of 300 metres, followed by a second sump penetrated for 780 m. On that same trip the sump was pushed to 1250 m.

Jason then returned year after year, sometimes with other top divers, and sometimes on his own.

In 2009 the sump was passed after 5160 m – the longest sump to be passed in the world, to reach Sump 3. This was passed in 2011 and proved to be over 3 km long. From this point, the sumps became shorter and the amount of dry passage longer.

Sumps 2 and 3 are actively linked and are in fact one long sump of more than 8km in length.

in 2015 Jason returned solo. He traversed more than 10 km of sump to explore dry passage and find a sixth sump.

Nitrox Course

The Nitrox Course is an entry level to start utilizing enriched air nitrox as a breathing gas.

Scuba diving nitrox gives you more no decompression time, meaning more time underwater especially on repetitive dives.

This simple one-day course can be done in a matter of hours, and it is in fact “dry course”. You can technically complete the course without going underwater even though, you probably don’t want to miss the fun part?!

TDI Nitrox Course
Nitrox
Double benefit : More time underwater, where you like and shorter surface intervals !
 Objectives of the Nitrox course?
  • Learn more about nitrox mixtures
  • Extend your bottom time
  • Less surface interval
  • Do repetitive dives
  • Move forward with technical diving education
Course prerequisites:
  • Minimum age 18, 15 with parental consent
  • Minimum certification of open water diver or current enrollment in an open water diver course
What you will learn:
  • Techniques for getting more dive time by using enriched air nitrox
  • The benefits, hazards, and proper procedures for using nitrox mixes from 22 through 40 percent oxygen content
  • Enriched air considerations, including managing oxygen exposure
  • Enriched air scuba diving equipment considerations, cylinder labeling, analyzing nitrox mixtures, and gas blending procedures
  • Manage oxygen exposure.
  • Analyzing oxygen content in your scuba tank.
  • Set your dive computer for diving with enriched air nitrox.

Structure of the Nitrox Diver Course:

  • There are two options for this Course:
    Option one: Standard Course
    Option two: Course with 2 Cenotes Nitrox dives
What gear will you use?

Your Instructor will help choose and let you know if your gear meets the requirements.

  • Regular modern scuba equipment
  • Dive computers
  • Scuba tanks must meet oxygen service standards and be dedicated for use with enriched air.
  • Oxygen analyzers
  • Special cylinder decals.
Next Step

Now that you earned your certification and will extend your dive time, you might consider moving to the next level
