Harlow Sub-Aqua Club

Dive on Maureen of Dart

I have "Maureen of Dart" booked for three days liveabord from 21 to 23 June

This long weekend is being arranged predominantly for Sport Diver Level or people close to achieving this (or above). We plan to dive wrecks in the range of 15 to 30m between Dartmouth and Plymouth with at least two dives per day. We plan to dive wrecks such as the Maine, Persier, Scylla and James Egan Layne as well as possibly some scenic diving such as Hands Deeps and Edison.

You will need a full set of diving kit including one main cylinder (ideally 15L) plus a pony cylinder if possible (not obligatory but recommended). Please also bring a torch and DSMB.

The cost for the full 3 days diving, air fills plus all meals from breakfast on 21 to lunch on 23 June (and believe me these are worth the trip alone!) is £250 per person. There is an additional cost for any nitrox used plus car parking. A deposit of £80 secures your place and the balance will be required by the 1 June 2008.

If you are interested please contact Jim Ridings

Decompression Sickness

It happens!

Below are a few of the incidents from BSAC’s Diving Incident Report 2007, for your attention. You will note that some of these incidents should not have happened, these dives were planned and the plan carried out, but divers still got hit.

We have had 2 None club members with bends from DCI, and both have continued diving, we do not want anymore, however if divers are careless or loose buoyancy, it could happen. You could complete a perfect dive and still get affected, it happens!!. The moral of the story is, the better you are prepared (training and diving fitness), the less likely you are of getting the bends.

Club Pool

The Club now have exclusive weekly pool facilities at Brays Grove School, Harlow, each Tuesday evening between 7.00p.m. and 8.30p.m. Entry fees will remain at £2.00 for members, £2.00 for guest swimmers, £3.50 for guest scuba visitors. The cost to the Club is £40.00 per week, so we encourage all members to turn up each Tuesday whenever possible, in the meantime, we shall now recommence advertising for Try Dives, new members and training now that we have an established venue. The venue however is expected to be temporary until we negotiate a place at Stewards when their pool eventually re-opens, but remaining in Harlow has been seen as a priority by most of the membership.

At the moment there are no immediate plans to move the Wednesday evening Club night from Moot House, but it would help Andy if air is required to organise this from 6.30p.m. onwards on a Tuesday evening until further notice.

scientific whales

Ocean scientists have recruited wild arctic whales to their team to probe the waters deep beneath an Arctic island fjord for the first time.

Sensors attached to the backs of the whales collected data as they dived deep beneath the fjord. The data was relayed back to the researchers via a satellite link each time the whales surfaced.

The sensors revealed a previously unknown influx of warm North Atlantic water beneath the Storfjorden Svalbard Arctic fjord during the winter months. It is not yet understood whether this is part of long-term climate change or shorter cyclical change that occurs over decades.

The Norwegian and British researchers attached sensors to the backs of white whales. These are known to feed at great depths and can easily descend to 200 metres to the bottom of the fjord. Extensive ice cover makes it nearly impossible for scientists to monitor the region using sensors deployed from ships.

Michael Fedack, a biologist at the University of St Andrew's Sea Mammal Research Unit in Scotland, says the whales were an extremely efficient way of gathering information from this inaccessible area.

Warm tongue

"The measurements show an interesting tongue of warm and possibly salty North Atlantic Water," he told New Scientist. "An important aim of the study was to show the oceanographic community that this could be done in a scientifically profitable and cost effective way."

He says the new approach can provide vital information to allow us to understand better the distribution of marine species and protect vital parts of their ecosystem. "And this fjord is an important one in terms of biology, with Ring seals, beluga whales and polar bears all making extensive use of it," he says.

Sophisticated Satellite Relay Data Loggers (SRDLs), which are normally used to relay information about the whales' movements, were modified to record the whale's depth and the temperature and salinity of the water twice a second.

Each time a whale surfaced the information was transmitted via satellite back to the researchers. The data was compressed while aboard the whales to improve the efficiency of the data relay.

Other research teams have attached sensors to whales and seals in order to track their movements and monitor ocean temperature. But those instruments have had to be recovered in order to retrieve the data. Fedack adds that other new remote sensing technology, such as robotic buoys, are helping scientists monitor the oceans better

Baggage allowance

BA confirms new baggage allowanceBA has confirmed that from February 13 2007 it will move away from pure weight restriction to a 'per piece' baggage arrangement. Each person can check in one piece of baggage up to 23ks whilst hand luggage will have to conform to size restrictions but no weight restriction. One piece of sporting equipment baggage can alo be carried free, weighting up to 23ks.

free air

free air to all members just bring your bottles along to the compressor hut and we will fill them up (we are getting around 220bar after are new refit in the hut)
as most of you may know the hut is open on a Wednesday from 7o'clock but if you need air other times you could try contacting andy,neil or alan and see if they can help you.
if you are not a member of the club you can still get air from andy on a Wednesday night but will have to pay for it so why not become a member and get it free (the hut is at the rear of the Moot House ,the stow,Harlow we will be pleased to see you

New web site up and running

New improved website is now online - you're reading it!

Please inform Angela if you have any of the following for the web site:

Anything that you find that requires amending.

Any thoughts/ideas/additional content to be added to the site.

Do you have a review of a holiday/trip you have been part of with the Halow SAC publish it for all to see maybe then they will want to join the next trip.
