2019 Was 2nd Hottest Year Globally on Record, and Oceans are the Warmest They've Ever Been Lots of articles out there similar to above. The ocean is the warmest it has ever been. 2019 was the second warmest year on record. 2016 hottest. The graphs in that article show a pretty significant...

Rash guard comes from Australia where they refer to sunburn as rash. Hence rash guard.

It really is not about breathing control, but heart rate control. There are breathing techniques mentioned here (like the long exhale) that help reduce your heart rate which in turn reduces the amount of breathing necessary. Being relaxed, being in shape and controlled breathing all...

Very basic chemistry supports man is causing warming. Fossil fuels release CO2. CO2 absorbs Infrared radiation and warms up. CO2 basically acts as a blanket. It is a simple concept to understand that blankets keep you warm, that black cars get warmer than white cars and that a thermos...

If a DM told me to split from my buddy, who happens to be my wife, I wouldn’t because I dont outsource my or my wife's safety. That being said, my wife and I often descend at different rates but our eyes are always on each other. If she is coming down slow, Im sitting there watching her...

To me, this article is driving to blame the DM. To me, these ops that turn DMs into underwater babysitters are just asking to get sued in the event of an issue. People think they are safe and take no personal responsibility for their dive. The part about the DM messing with buddies is...

I think this response is relative. Is it a challenging dive? No. Coming from the Caribbean I found the crater stunning. The visibility is pristine. As a fan of reef fish, the angels and butterflies there are so beautiful. With the great visibility it is a fantastic dive. I was...

Your issue is with the hose routing. If you had the 40" hose coming out the bottom of your turret and at a 45 degree angle, the hose would route perfect. You could also try changing which LP port the hoses come out as well. You could try swapping your primary and secondary. Your...

Other than reducing the number of boats and increasing business for existing operators, exactly what has been accomplished here? I realize someone is going to say too many divers, but that is relative. If the goal was to stop fish poaching, now we are talking. To me however, this is...

If you are any experienced diver I would not dive with Mike Severns. They are very knowledgeable about the local reef inhabitants. However, their operation caters to low skill divers and they want everything running a certain way. For example, they insisted on assembling gear and then did...

The difference is that when I stay at a hotel, or drive my car or go diving, my trash doesn't get dumped in the middle of the ocean. The impunity with which these ships dispose of their waste is the difference.

I like the Iberostar for family vacations. Dressel is definitely very inexpensive if you prepay and buy a weeks worth of 2 tanks...and Nitrox is free....and they fill their own tanks so you actually get 3100 psi...BUT...the diving is meh. When I stay there I have one of the other dive ops pick...

Appreciate your feedback, but you need to stop saying its 90 vs 45 minutes. You can find ops to let you dive your tank if you want that. I certainly dont do 45 mins in Coz. A fair comparison is boutique to boutique Op.

I've always wondered how the Aldora dives are structured. For reference, I can pull 60-70 minutes out of an AL80 and my wife is even better. Not all dive sites at Cozumel are continuous and it seems that many run out of reef at around 6-70 minutes and you end up over sand or the abyss...

To me these threads always break down to two related questions: Do you want your DM to be a guide underwater leading the group? Or do you want the DM to be underwater fulfilling the legal requirements for a DM and leave you alone? If you want the later and dive with the former, you are...

I was in Coz the first week of Nov and your assessment matches my assessment 100%. The brain corals are wiped out, bleached fire coral, many other heat stressed/bleached hard corals, etc. Way too much algae and now there are sunk sargassum piles everywhere. The sargassum is going to...

Ha! Ironically I thought exactly that...."at least it is coralline algae growing and not nuisance algae." It does signal a certain amount of reef health.

My wife and 2 friends were in Cozumel last week. We were there in April this year as well as April last year, etc... Additionally, for years I very successfully maintained a reef tank that grew stony corals from traded fragments. I consider myself very familiar with coral health and growth...

Ok great! Those gusts scared me but I see your point on the direction.

Port closed today. Windguru looks good for tomorrow and Tuesday. But Wednesday and Thursday are not looking good. :(
