Red Sea Suggestions
I'm starting to plan a 25 day trip to Egypt.
I want to split it up where I'll be diving from boats from a resort
7 to 10 day liveaboard and send my gear home and then go to the markets, museums, and pyramids.
As I said I'm just starting the planning today so any help or suggestions are appreciated.
Normally I'll stay at a place with simple accommodations bed, shower, TV, Internet, aircon and then dive at the resort.
I am thinking about taking my ssi master diver course if it's available.
Thanks for the help in advance.
Diving in April
Any recommendations for the first week of April? I've got 120+ dives logged, my girlfriend has about 30. Based in UK.
Dear Scuba Travel
I really enjoy your very informative guide for the diver and traveler such as myself. Im actually emailing in hopes that you can assist me with something.
I am working on a guide for divers, new and old, and im trying to gather as much information as possible. Your website is perfect for destinations and is so informative and helpful, but I wish to gather my own information with your help.
Seeing as you have first hand accounts, by the divers to pass on to the divers, I was wondering if you would be able to circulate two surveys i have made. One for the experienced diver, one for the inexperienced. They are at

In Reply to previous Letter on easy, good, warm diving within reach of Vancouver.
Try Baja, wonderful fish populations. I love St Croix, great conditions, easy diving and the best pier in the world! I can dive 90 minutes on a single tank at 20 ft. Shore diving is simple there and is much cheaper than boat diving. Key Largo, also easy diving in terms of depth and conditions. Just don't go in August, jellyfish!
I recently became a dive professional at the age of 55 and am now working in St. Croix. I love helping people find the perfect places to dive! Your site is really a wealth of info and I will share it often. I am presently in Barbados, diving the wrecks and reefs, doing a preliminary assessment of the island as a location for a coral reef restoration course and a marine archaeology certification.

Which sunscreens are safe for sea life?
It’s a minefield trying to buy a sunscreen which doesn’t harm the sea life. Even those trumpeting their green credentials are not always free from harmful chemicals and components. You have to read the label very carefully. So what are the nasties of which scuba divers and snorkellers should be wary?
Nano particles are minute chemical substances, which are about 100,000 times smaller than the diameter of a human hair.
Titanium dioxide and zinc oxide nanoparticles are often used in sunscreens. They allow clear sunscreen which can be sprayed on. However, they produce significant amounts of hydrogen peroxide, a strong oxidizing agent that generates high levels of stress on reef-building corals and marine phytoplankton. They have also been shown to make sea urchin embryos more vulnerable to toxins.
You need to avoid nanoparticles if you are looking for a marine-friendly sunscreen.
A study by Dr Craig Downs published last year showed Oxybenzone (also known as Benzophenone-2 or BP-2) increased the rate of coral bleaching. Additionally, the chemical damages the coral’s dna, affecting their reproduction. If that wasn’t enough other effects are to make juvenile corals become grossly deformed and encase themselves with their own skeletons.
Octinoxate, Butylparaben, 4-Methylbenzylidene Camphor
Another study, this time by Roberto Danovaro, named butylparaben, octinoxate and 4-methylbenzylidene camphor as being harmful to reefs.
How Much of a Problem is it?
According to NOAA (National Oceanic and Atmospheric Administration) 4,000 to 6,000 tons of sunscreen enters reef areas annually. This does not spread out rapidly or evenly over the entire ocean, but concentrates on popular tourist sites. It is estimated that 90% of snorkellers and scuba divers are concentrated on 10% of the world’s reefs.
So which sunscreens can you use?
Look for ones without the ingredients mentioned above. Zinc oxide and Titanium dioxide are good as long as they are not in nano-format. A quick guide is whether the sunscreen is clear or not. If it is clear, or in a spray, it probably contains nano-particles.
If the ingredients state “uncoated” zinc oxide then these are larger particles (non-nano) and safe.
Some examples of sunscreens which safe for sea life are:
Badger Sunscreen Unscented
Lovea Natural Sunscreen Spray
