Manuale Teorico-Pratico per Corsi di Immersione di I Livello con Autorespiratori ARA
La FIAS (Federazione Italiana Attività Subacquee) grazie ad un’esperienza trentennale, si è adeguata e aggiornata ai più moderni sistemi pedagogici e vanta, oggi, di una serie di sussidi didattici strutturati che consentono un apprendimento graduale e gradevole delle problematiche dell’immersione subacquea. Questo libro è il primo gradino dell’apprendimento. Non è e non vuole essere esaustivo su tutti gli argomenti ma solo condurre, con l’aiuto indispensabile e insostituibile degli istruttori, alla conoscenza minima richiesta per iniziare l’attività subacquea. A questo testo ne faranno seguito altri due che completeranno e approfondiranno tutti gli argomenti necessari per formare un subacqueo esperto secondo un programma ampiamente collaudato. Al termine dell’iter formativo il subacqueo potrà specializzarsi in tecniche complementari all’immersione quali fotografia, video, archeologia, biologia e altro ancora, oppure approfondire aspetti tecnici dell’immersione come l’immersione in quota, l’immersione notturna, l’immersione con miscele ossigeno-azoto e così via.

IMPORTANT SAFETY NOTICE!

UPDATE OF – NEMO AIR QUICK CONNECTOR RECALL -

Dear Customer,

As you know we have discovered a quality issue on the O-ring assembled on the Nemo Air quick connector.

Under certain circumstances the O-ring can fail and consequently Nemo Air may start leaking through the Quick Connector. As a result, there is a continuous, albeit slow, loss of breathing gas. This situation could potentially lead to an accident, hence Mares has decided to issue a product recall.

The solution indicated was to substitute the existing  O-ring with a new one of different material and hardness.

Even if above solution is already improving Nemo Air Quick Connector performance, we further investigated in order to obtain the maximum performance and reliability and we have found that, in severe conditions, even with the new O-ring NEMO AIR QUICK CONNECTOR was leaking.

We have therefore designed a NEW NEMO AIR QUICK CONNECTOR ASSY FEMALE (code 44200829) featuring a new seal and seat. This solution is fully satisfactory.

We ask you therefore TO REPLACE the mentioned QUICK CONNECTOR ASSY FEMALE with the new one.

NONETHELESS FOR YOUR PERSONAL SAFETY AND TO AVOID POSSIBLE DANGEROUS ACCIDENTS: STOP DIVING WITH A QUICK CONNECTOR SUBJECT TO THIS RECALL UNTIL THIS IS NOT REMOVED AND REPLACED WITH THE NEW ONE.

• Affected products and codes are:
1. Finished goods
414158 – DIVE COMPUTER NEMO AIR
414159 – DIVE COMPUTER NEMO AIR W/COMPASS NO
2. Spare parts
44200771 – HP HOSE W/QUICK CONNECTOR NEMO AIR
44200770 – QUICK CONNECTOR ASSY. FEMALE NEMO AIR

PLEASE CONTACT THE NEAREST AUTHORIZED MARES SERVICE CENTER TO SCHEDULE THE REPLACEMENT OF YOUR NEMO AIR QUICK CONNECTOR.

REMIND THAT NEMO AIR QUICK CONNECTOR MUST BE REMOVED AND SUBSTITUTED WITH THE NEW ONE AT NO CHARGE.

WWF-STUDIE: TIGER DER SUNDARBANS DURCH WILDEREI, WALDRODUNG UND KLIMAWANDEL BEDROHT

Eine der größten Tiger-Populationen der Welt könnte bis zum Ende des Jahrhunderts ausgestorben sein. Ihr Lebensraum, die Mangrovenwälder an der Küste von Bangladesch, ist nach den Ergebnissen einer vom WWF geleiteten Studie durch den vom Klimawandel verursachten Anstieg des Meeresspiegels bedroht.

“Wenn wir die Auswirkungen des Klimawandels nicht in den Griff bekommen, werden die Tiger in den Sundarbans nur mit Tauchausrüstung überleben können”, erklärt WWF-Tigerexperte Volker Homes. Auch wenn Tiger sowohl in den im Winter schneereichen Wäldern Russlands als auch im tropischen Regenwald überleben können. “Der von Wissenschaftlern prognostizierte Anstieg des Meeresspiegels würde die Anpassungsfähigkeit des Tigers mit sehr großer Wahrscheinlichkeit überstrapazieren”, so Homes.

Wenn nicht sofort Schutzmaßnahmen ergriffen werden, könnten die Mangroven-Wälder mit all ihren Naturschätzen, die Millionen
Menschen ernähren, innerhalb der nächsten 50 bis 90 Jahre untergehen, so das Ergebnis der Studie, die im “Climatic Change” Journal erschienen ist. Ein Anstieg des Meeresspiegels um 28 cm über den Stand des Jahres 2000 würde 96 Prozent des Tiger-Lebensraumes zerstören und die Population auf wenige Exemplare minimieren.

Tiger sind weltweit bereits durch Wilderei und die Abholzung der Wälder bedroht. Ihr Verbreitungsgebiet ist im letzten Jahrzehnt um 40 Prozent geschrumpft. “Tiger werden für ihr Fell gejagt, ihre Knochen werden illegal für die traditionelle asiatische Medizin genutzt und jetzt werden sie auch noch von den Auswirkungen des Klimawandels bedroht”, so Homes. “Wir befürchten, dass diese Vielzahl an Bedrohungen die majestätische Raubkatze an den Rand des Aussterbens bringen wird.”

Die Sundarbans sind die größten, zusammenhängenden Mangrovenwälder der Erde. Das UNESCO Weltnaturerbe verläuft entlang der Mündung des Ganges in Indien und Bangladesch. Sie sind nicht nur die Heimat für rund 200 Tiger, sondern auch für zahlreiche Arten von Reptilien, Fischen, Vögeln und Säugetieren.

Nach dem chinesischen Kalender beginnt am 14. Februar 2010 das “Jahr des Tigers”. Weltweit gibt es nur noch rund 3200 Tiger in der Wildnis. Die Umweltschutzorganisation hat sich das Ziel gesetzt, die Bestandszahl des Tigers in seinen wichtigsten
Verbreitungsregionen bis zum Jahr 2022 zu verdoppeln.

English description

“An eye-opening film…visually stunning… this movie will change the way you see our oceans.”
- Bonnie Laufer,
Tribute Magazine

For filmmaker Rob Stewart, exploring sharks began as an underwater adventure. What it turned into was a beautiful and dangerous life journey into the balance of life on earth. Driven by passion fed from a life-long fascination with sharks, Stewart debunks historical stereotypes and media depictions of sharks as bloodthirsty, man-eating monsters and
reveals the reality of sharks as pillars in the evolution of the seas. Filmed in visually stunning, high definition video, Sharkwater takes you into the most shark rich waters of the world, exposing the exploitation and corruption surrounding the world’s shark populations in the marine reserves of Cocos Island, Costa Rica and the Galapagos Islands, Ecuador.
In an effort to protect sharks, Stewart teams up with renegade conservationist Paul Watson of the Sea Shepherd Conservation Society. Their unbelievable adventure together starts with a battle between the Sea Shepherd and shark poachers in Guatemala, resulting in pirate boat rammings, gunboat chases, mafia espionage, corrupt court systems and
attempted murder charges, forcing them to flee for their lives. Through it all, Stewart discovers these magnificent creatures have gone from predator to prey, and how despite surviving the earth’s history of mass extinctions, they could easily
be wiped out within a few years due to human greed.
Stewart’s remarkable journey of courage and determination changes from a mission to save the world’s sharks, into a fight for his life, and that of humankind.

This is the 2 minute trailer.

Deutsche Beschreibung

Ungewöhnliche Titelhelden in einer spannenden und bewegenden Geschichte: Der faszinierende, in Atem beraubend schöne Bilder umgesetzte Film SHARKWATER ist weit mehr als nur eine qualitativ herausragende Dokumentation. Elegant verbindet er Schönheit und Grausamkeit des Lebens im Ozean miteinander.
Regisseur Rob Stewart, Fotograf, Taucher und passionierter Hai-Kenner, wollte mit den Vorurteilen aufräumen, die Menschen gegenüber Haien haben. So zeigt SHARKWATER in berauschenden Aufnahmen diese außergewöhnlichen und vollkommen friedlichen Tiere in ihrem zunehmend eingeschränkten, bedrohten Lebensraum.
Doch aus dem Film, der vor allem die Schönheit des Meeres einfangen wollte, wurde ein rasanter Abenteuer- und Actionfilm. Denn die Fischerei-Industrie zahlloser Länder ist stets auf der Jagd nach Haien, diesen majestätischen Kampfmaschinen der Meere ¬ das heißt eigentlich nur nach ihren Flossen. Als Bestie verflucht, als Delikatesse begehrt, haben die Haie keine Lobby. Ihre Bestände haben sich in den letzten Jahren bereits drastisch dezimiert.
Während der Dreharbeiten gerieten Regisseur und Crew immer tiefer in ein lebensgefährliches Netz aus Kriminalität und Naturzerstörung, dessen fatale Folgen bereits deutlich sichtbar sind. Stewart betreibt in dem grandios bebilderten SHARKWATER nicht nur Aufklärungsarbeit über Wesen und Natur der Haie. Seine großartige, packend erzählte Dokumentation ist auch ein eindringliches Plädoyer für eine Neudefinition der Beziehung zwischen Mensch und Tier.

Description française

Depuis l’enfance, Rob Stewart se passionne pour les requins. Il est devenu biologiste et photographe sous-marin afin de pouvoir nager avec eux, décrypter leurs mystères et déconstruire le mythe du requin mangeur d’hommes.
Des dernières réserves du Costa Rica jusqu’aux îles Galápagos en passant par le Guatemala, Rob Stewart et l’équipage de l’activiste des mers, Paul Watson, tentent de mettre en échec les braconniers à la solde de mafias asiatiques soutenues par des gouvernements corrompus. Il y va de l’équilibre écologique de la planète…
À la fois document militant et acte d’amour, entre scènes très violentes et d’autres d’une grande beauté, “Les Seigneurs de la Mer” plaide pour l’urgente sauvegarde des requins.

Nederlandse beschrijving

Passie en een levenslange adoratie voor haaien dreven Rob Stewart er toe een documentaire te maken waarin oude vooroordelen en stereotypen betreffende haaien ontkracht worden. Hij reist naar de wateren met de meeste haaien ter wereld en toont ons het belang van haaien in niet alleen de evolutiegeschiedenis, maar ook de huidige ecologie. Tevens neemt hij het voor hen op als bedreigde diersoort en krijgt hij hierdoor te maken met onder meer piraten, maffia en militairen. We zien hoe haaien langzamerhand van roofdier tot prooi zijn verworden.

Cuba

My son and I are planning to visit Holguin, Cuba, between Dec 27th and Jan 3rd. We have no diving experience other than having done a bit of snorkelling. We are hoping that while we are down there, we could obtain basic diving certification, and maybe even a few dives if possible. We are staying at the PLAYA PESQUERO, in Holguin. Do you know if this is possible, and if so, do you have any suggestions as to who I should be contacting to arrange things.

Creature of the Month: Burrowing Anemone, Cerianthus lloydii
==========================================================

This common European species is not a true anemone. Instead of attaching itself to a rock it lives in a soft tube protruding above sand or mud.

The animals’s tentacles are usually all that is visible. The inner set circle the mouth and are short and stiff. The long, flexible, attractive outer ones, over 100 of them, sweep prey inwards. When disturbed the whole anemone shoots back into its tube, like a tubeworm. The tentacle crown measures up to 10 cm across.

The burrowing anemone lives from the shallows down to 100 m. The tentacles may be white, brown, green or banded.

You find this anemone from Norway down to the Bay of Biscay.

Shark fin traders admit selling endangered species

Hong Kong shark fin merchants have reacted angrily to a US study that said meat from endangered species was being sold in the city’s markets. US scientists found 21 per cent of the fins came from endangered scalloped hammerhead shark stocks in the western Atlantic. But the Hong Kong Shark Fin Trade Merchant’s Association said its members had not done anything illegal. A spokesman said “We are not doing anything against the law. The sale of endangered scalloped hammerhead shark fins has not been made illegal here.”

IUCN warns of acid oceans and mass extinctions

Increased release of carbon dioxide in the atmosphere is making sea water more acidic and is threatening ecosystems and species. It is also reducing the ocean’s ability to absorb carbon dioxide and regulate climate. According to IUCN), deep and immediate cuts in emissions are needed to stall the acidification of oceans and prevent mass extinction of marine species.

‘Shocking’ 95% Decline of Fish Populations

Populations of numerous migratory fish species – those that move between freshwater and saltwater during the course of their lives – have declined by a shocking 95 percent.

NOOA remove restrictions on swordfish fishing

Environmentalists believe the new regulations will harm turtles, sharks, albatross, dolphins and other species accidentally caught in the fishery.

Atlantic Hurricane Season Closes: Less Storms This Year

The 2009 Atlantic hurricane season officially ended 30 November marking the close of a season with the fewest named storms and hurricanes since 1997 thanks, in part, to El Nino.

Ancient Mediterranean flood mystery solved

Research has revealed details of the catastrophic Zanclean flood that refilled the Mediterranean Sea more than five million years ago. The flood occurred when Atlantic waters found their way into the cut-off and desiccated Mediterranean basin. The researchers say that a 200km channel across the Gibraltar strait was carved out by the floodwaters. Their findings, published in Nature, show that the resulting flood could have filled the basin within two years.

Melting sea ice dilutes water, endangers sea life

Melting of the Arctic sea ice due to global warming is diluting surface waters and this is endangering some species of shellfish which need minerals in the water to form their shells and skeletons, scientists have found.

Oceans Absorb Less Carbon Dioxide as Marine Systems Change

The oceans are by far the largest carbon sink in the world. Some 93 percent of carbon dioxide is stored in algae, vegetation, and coral under the sea. But oceans are not able to absorb all of the carbon dioxide released from the burning of fossil fuels. In fact, a recent study suggests that the oceans have absorbed nearly 10 percent less fossil-fuel emissions since 2000. The study, published in the current issue of Nature, is the first to quantify the perceived trend that oceans are becoming less efficient carbon sinks.

Sea cucumbers face depletion once more

A new extension to the sea cucumber harvesting season, and an increase in licences, is going to drive stock back a decade to near depletion, Tongan officials fear.

NEMO WIDE: the best interface between man and sea is now available with two new functions!!

• Wide display with superior
readability
• Ergonomic design and intuitive
interface
• Upgradeable software
Nemo Wide was designed to be easy-to-read, intuitive to use, safe, and reliable. A large size display was one of the primary requirements behind its creation. In order to optimize readability in every circumstance, special attention was paid to the size and brightness of digits, to the backlight intensity and to maximizing the viewing angle.

With Nemo Wide Upgrade 3.0 (3 gas algorithm) is avaialble to download from our web site (download/computer)and allows you to use up to three different Nitrox mixes during the dive (including air):

• Bottom mix (21-50%)
• Travel mix (21-99%)
• Deco mix (21-99%)
You must define the mixes in the dive computer prior to beginning the dive. You’ll be able to set the oxygen concentration and maximum oxygen partial pressure (ppO2max) for each mix individually, for maximum flexibility to suit your dive style.
During the dive Nemo Wide will suggest when you ought to switch to a different gas, and all you have to do is push one button to confirm. Nemo Wide will immediately recalculate your decompression based on the new information. 
And … if you already own a Nemo Wide you can simply upgrade your dive computer by downloading the new firmware from our web site, then installing it via Mares Drak and you’ll immediately have this function available.

The other function available with the new firmware is Stopwatch in bottom time mode. The upgrade adds a stopwatch function when Nemo Wide is in Bottom Time mode. 

Do you wish to be a cut above the rest? Once more with MARES it is possible … Enjoy pure perfection …
