WORKSHOPS

We host classes and workshops organised by external instructors and experts renown for their unique talents and skills. Areas of interest include underwater photography, underwater videography, cave survey, mapping and cartography, scientific diving, CCR diving and sidemount diving. 

We support Phreatic project, who aims to boost citizen science fostering the interaction between cave divers and researchers on the field; Phreatic activities involve and coordinate a network of cave divers cooperating with science experts and deliver reliable results in areas where generally scientific research is not conducted due to the complexity of the environment. 

 

CAVE DIVING SARDINIA

The Gulf of Orosei and its forty kilometres of development are one of the last areas of the Italian coast without buildings or roads, with a wild terrain behind it, difficult to penetrate and access even walking: the Supramonte limestone plateau. The coastline is one of the most beautiful geological scenarios in the Mediterranean area; high cliffs of white limestone dropping down into turquoise water and carved during geological eras by winds and the force of the sea. In this interface there are hundreds of caverns and caves (both dry and flooded), with some of the longest underwater cave systems of Europe. These springs are fresh water rivers with intrusion of saltwater from the sea. Multiple decorations and speleothems testify to the varying water levels during different ice ages and prove such environments were once dry; multiple branching passages, sumps and long shallow galleries make these caves the premiere cave diving destination in Europe and a maze still to be discovered and explored.
Main springs:
 
– Grotta del Bue Marino
– Bel Torrente
– Risorgenza di Cala Luna
– Utopia and Euforia
– Grotta del Fico
– Maseduoe
Each of them is incredibly different from the others, offering a lot of variety. Most caves present spectacular halocline, hydrogen sulphide, speleothems and varying morphology with vertical shafts, big phreatic passages and restrictions alternating themselves. 
The average depth in most systems is extremely shallow (avg. 9 meters) with water temperatures of about 22 degrees in salt water and 15 degrees in the fresh water. These conditions allow for long bottom times and very limited decompression in caves with branching passages and very good visibility. 
Other systems are deeper and require advanced planning to execute more complex dives, with longer exposure and decompression times; an ideal scenario for rebreather cave dives.
This area offers also a lot of opportunities for sump diving and side mount passages, depending on divers’ level of experience and commitment.

Nothing compares to exploration

BEHIND BASE1

SERVICES

ALESSANDRO FENU

Alessandro has been diving since 1981 and in the early 90’s he located and explored wrecks in the North of Sardinia. In 2000 he took part in the Pag Island Wreck project that led to the discovery of six deep wrecks. As a member of the EKPP, he took part in several projects as support diver. He joined the WKPP in 2007. 2011 onwards he has led the FLD Team which comprises 25 active cave divers. He leads explorations and mapping projects, mostly in the Northern Italian Caves, accomplishing long dives in cold water. Inspired by his passion for diving and his desire to improve diving equipments, in 1999 he co-founded “Suex – The Submarine Exploration Company” with his business partner Marco Segatto.  Main goal was to manufacture a high performance diving vehicle for all professionals, explorers and deep divers but also for Military applications. Beyond being an eager and passionate underwater explorer for more than 20 years, he trains the military Spec Ops on the Suex DPV use and management.

ANDREA MARASSICH

Being a diving educator by profession and a cave diver by passion, Andrea spends most of the year in the island of Sardinia, teaching cave diving and running scientific/documentation and exploration projects in the underwater caves of the gulf of Orosei. He regularly dives the caves of Mexico, Florida and France, where he runs similar activities but with different groups and pursuing different goals.  As he is involved in multiple exploration, conservation and research projects all over the world (Italy, France, Bosnia & Herzegovina, Slovenia, Portugal, Spain, Mexico and Florida), he had the chance to meet and connect to many people, divers and non-divers alike, that can offer unique skills and capabilities; working with this network of researchers, divers and media experts is a key component of his job. In the last six years he has been leading the activities of Phreatic, encompassing both exploration and citizen science initiatives, focused on data collection, cave survey, cartography and 3D modelling using photogrammetry techniques.
