Ear Cleanliness

My ears often give me trouble after an extended period of diving - you know, like after a live aboard, or a long vacation with several days diving.

Here's a DAN article with some useful things to try.

Scuba Diver Salvages Lost Treasure - Dubai Blog

http://www.dubayblog.com/scuba-diver-salvages-lost-treasure/

Forwarding this to highlight all the things that are wrong about this story.

I thought we had a saying in the diving community: Take nothing but pictures, leave nothing but bubbles.

Anything you take with you on a dive needs to be secured to you with a lanyard or retractor.  It's too easy to accidentally, or intentionally, let go of something on a dive.  If it isn't clipped to you, you WILL looses it.

When something is in the water for a period of time, marine life will move in.  An old coke can may be junk when it gets dropped off the side of a boat, but after a short period of time, marine life will move in to investigate.  It may become a home for a snail, crap, octopus.  You cannot remove things from the ocean that have become part of that environment.  By the looks of the camera, it has been down there a while, and I'm pretty sure something was living on it judging by the condition of the outside of the housing.

The worst part of this story is the fact that it took the guy several minutes to extracate the camera from the rocks and CORAL.  I find it hard to imagine that this could have been done withouth causing damage to the environment.  Coral is a very slow growing, fragile ANIMAL.  Divers climbing over it, yanking at it, breaking it off, just to get to a lost camera is not worth it!

Two lessons to learn from this then:
- Don't loose your stuff when you go diving
- Don't bring things out of the water if they look like they've been claimed by the ocean.

Diving McAbee Beach - Night Dive - Feb 25, 2015

McAbee Beach Night Dive

Site Description

McAbee beach is a dive site on Monterey's Cannery Row. The dive site is accessed from the small beach between the El Torito restaurant and the Spindrift hotel.

Street parking is available, metered. There is also a lot across the street, which charges by the day. The El Torito restaurant also has a parking lot, however, El Torito do not appear to be welcoming of divers in there lot at the moment (parking tickets have been issued recently!).

Enter the water around the center of the beach, the is where the water is the calmest. Be aware of the drop-off, the beach has a shelf. A small problem on entry, and on exit - for short divers it can make the exit on this beach tricky. Swim away from the beach quickly, and bear towards the El Torito side of the beach.

Plan to dive closer to the El Torito side of this beach (South East), this is the calmer water. If you dive towards the North, the water is shallow, and the surge and waves can become dangerous.

On this dive, we dropped down just outside the rock-wall surrounding the El Torito restaurant. We dove the plan shown below.

What to see on the dive

At first we swam parallel to the shore and the water remained pretty shallow (20ft). You will see plenty of old cannery pipes and plenty of rocks. We saw rock fish, decorator crabs. Also, in under the rocks I saw a good size octopus. I was hoping the pipes would have some eels, but wasn't lucky enough to see any.

As we swam out from the beach (30degree heading) we got more kelp. The depth dropped to around 30ft for a while. There were still plenty of rocks, although the bottom did opened up a little and there were several sandy patches.

Swimming back in, it got more rocky, gradually shallower, and a little surgy as we got in above 20ft.

Video

Here's a Critter Montage video. If you look carefully, around 45seconds in, you can see the octopus hiding in the rocks.

Night Dive at McAbee Beach, Feb 25 2015

Metridium Fields and Breakwater Dive Oct 25 2014

Dive to the metridium fields this weekend with a couple of dive buddies from the Dive Club of Silicon Valley.

We dove to at the metridium fields, as one of my buddies had not had the opportunity (or good fortune) to find the metridiums when he'd tried it in the past.

Recently I've taken the approach of descending nearer to shore and following "the pipe" out to the metridiums (see earlier maps). However today we swam out further, to save air, and dropped right down on the metridiums.



The advantage of avoiding the swim out underwater is that you then have enough air to make the long swim parallel to shore, to exit at the breakwater. This makes for a different dive from usual. Infact, this is the first time I've done this and it's a nice way to end a metridium dive.

I was expecting the bottom to be entirely sandy and barren, with the occasional halibut for company. But as the video shows, there are several rocky oasis on the journey, with plenty of marine life to enjoy.

Looks kinda nice.  I'm not sure I'd pay 95 euro for something like this though. But if someone wants to send me one, I'll give it a try. Could be a good seller for our next Dive Club of Silicon Valley annyal Snorkel Safari

Dive to Metridium Fields, Monterey, CA

Managed a repeat of the Metridiums dive this weekend.

Visibility was about the same as last month, maybe a little better.

Took my GoPro this time, so captured some video of a Metridium. Unfortunately, I didn't have my green water filter on, so the colors are somewhat messed up.

Turtle in Belize

My son had been wanting to see a turtle the whole time we were diving in Belize. If fact, even before we got there. Luckily, on the last dive, of the last day, we got to see one!



And to think, we were supposed to be diving out at Turneffe Atol that day. Good job the trip got cancelled eh!

Diving Metridium Fields Monterey, April 19, 2014

Dive Site

Metridiums Fields, San Carlos Beach, Monterey, California.




Click for fullsize image or Google Map


The Metridium Fields site is a beautiful dive site located at San Carlos beach in Monterey. San Carlos beach, also known as The Break Water by many local divers, is a very popular site. If you dive closer to the breakwater wall, you will be diving amongst the hordes of open water dive classes. However, further away from the wall, and a long swim from the shore, is the spectacular Metridium Fields.

Reaching the Metridium Fields requires a rather long swim. If you do it underwater this will limit your time at the dive site. If you do it on the surface you will be getting close to boat traffic. On this dive we had Diver Propultion Vehicles (DPVs), so we were able to do the descend quite close to the beach yet still have plenty of bottom time once we reach the metridiums.

Actually I was taking the PADI DPV specialty.



You enter the water from the left side of San Carlos beach. There are stairs down to the beach near the restroom at the left side of the parking lot. Before you go down to the beach, familiarize yourself with the location of the pump house just behind the restrooms, as that will be an important visual landmark for the start of the dive.

Be careful where you enter the water. At this side of the beach there are a number of submerged rocks, and also exposed rebar (metal) from the foundations of the old cannery buildings. The beach here is quite well protected, so waves are usually not too large. However, as I say the rocks and foundations can be a hazard and you don't want to fall here should a rogue wave come along.

After entering the water swim away from the beach and, if looking towards the beach, out to your right (northerly). The drop off here is slow, so you need to swim out a way before it's deep enough to descend. You need to head more northernly, as you need to line yourself up with the pump house on the shore. You can also see the road, Reeside Ave, going up the hill behind the pump house.

Swim out away from the beach perpendicular to the pump house. As I said earlier, the further out you swim, the less swimming you need to do underwater to reach the Metridiums.

Take a bearing back to the beach before you drop down. Prefer a bearing towards the center of San Carlos beach rather than direct to the pump house, as you don't want to come ashore too far north here on your return - it's very rocky with no good beach north of the pump house.

Descend and head North. You should shortly hit the pipe. There are lots of small pipes around Monterey dive sites, don't be mistaken, at this dive site you are looking for a much larger pipe, about 2, or more, feet in diameter.

When you reach the pipe, follow the pipe out into deeper water (30degree heading). At the end of the pipe (the pipe ends abruptly) head North again. You will very soon hit the Metridium fields.

Once we reached the site we explored on a NE-SE direction. After completing the dive, we turned on a 180degree heading for a short while, to put us on a good path towards San Carlos beach, then turned to 240degrees. This put us on an intercept path with the pipe, which runs at 210 degrees towards shore.

Take time to look around the pipe, there is plenty of marine life living here. Nuibranches, crabs, rock-fish, sea-stars, and the occasional seal. Depending on the season, seanettles and moon jellies.

We ascended along the pipe. When we got to 15 feet we stopped for a safely stop on the bottom, alongside a nice Lingcod (which was resting on the pipe).

PADI DPV Specialty

As I said, I was participating in the PADI DPV Specialty Class. I can recommend the class, it's a great way to get some hands-on time with one of these fun toys without the outlay of cash. You will also learn about the various different kinds of DPV available, and our instructor took us through the various maintainance, assembly and disassembly procedures.

This dive site is an above average distance from shore, and reaching it is made much easier with a DPV.
