Fire coral: Beauty and the Burn

Wednesday, February 25th, 2009

My wife and I enjoy identifying the different fish, coals and critters (aka invertebrates) found on the reefs we visit.   I take pictures and video while diving, then in the evening we review them and try to identify any that we do not recognize.    In several video sequences, I captured the action of small fish darting in an out of leafy coral heads.  At the time I believed blades to be some form of encrusting coral.  Little did I know.

On closer inspection, there were small spines protruding from the surface.  This was fire coral!  After years of hearing divers warning me to watch out for fire coral, I finally found out what it looks like.   I assume the small fish I was observing were using the fire bouncy castle for sale coral for protection from predators as they darted in and out between the blades.

Fire coral is not actually coral, but a hydroid (more like a jellyfish).  The sharp calcified spines combined with the stinging cells called nematocysts present double trouble for anyone that comes in contact.   Bushing against fire coral can produce a painful sting which last for days.  Cutting your skin on fire coral can take long time to heal.  Since we strive to avoid contact with any coral, I’ve never been stung.  Hopefully these pictures will help others to avoid the burn.

Points to consider when buying dive gear

Sunday, January 25th, 2009

Any basic SCUBA class will tell you that the primary consideration when buying gear is fit. If it does not fit right, it will not function properly. The best example is the simple SCUBA mask. If it does not fit, it will leak, and fill with water. This not only defeats the purpose, but also adds a great deal of stress to the diver. Make sure your gear fits!

After fit, here are some other considerations you may want to keep in mind when making gear selection.

Intended use: Ask yourself a serious question: what type of diving will you be doing in 5 years? Your SCUBA gear will easily last that long. I still regularly dive the first SCUBA regulator I ever bought. Many fall victim of short sighted purchases. Then every few years, they sell all their gear, and buy gear that is better suited to the diving they are doing now.

Marketing claims: The newest or most expensive model is not always the best choice. Manufacturers are constantly trying to separate themselves from the others. Inflatable Water Slide There have not been huge changes in SCUBA technology in the last few years. Improvements in manufacturing practices have reduced the cost to make the gear, and exotic materials have made some of the gear more rugged. However, despite marketing claims, the basic function of the gear has not changed significantly.

Local Conditions: Ask a few local divers, or instructors, what type of gear they use and why. There are a few pitfalls to this approach. If their answer is one of the following, “it was a deal”, “someone else recommended it” or “That’s what our shop sells”, then look for another source. Keep in mind that shops recommend what they sell. That does not mean its the right gear for your local diving. Check out the diving experience of the shop owner (the one who purchases the gear). Make sure their diving matches your plans. If not, then the gear may not be suited to your diving conditions.

A good instructor will usually be upfront, but some are affiliated with a shop, and will promote the shop’s gear. Experienced divers will get the right gear for the job. Find out what it is and why.

Shop for features not brands: When talking with other divers, ask about the features they look for in the gear. During these discussions, leave the brand out of it. Most brands offer similar features. Or put another way, the features you’re looking for are probably available from several brands. The important part is to determine which features are important, and which are not. Some features, highly touted by the marketing types, may be a detriment in your diving conditions. Make a list of the features you want before stepping into the shop.

Which brand: Again, most features are available from several brands. How do we choose? Without going into the Chevy vs Ford issue, here are a few points to ponder:

  • Service: Some brands provide fantastic gear, but have very few locations for service.
  • Quality: Some brands have better manufacturing processes, and produce gear with better fit and finish.
  • Reliability: This often has to do with the quality of the materials used in the gear, and the quality of the engineering that went into it. Simple is usually more reliable.

Price: Why is this last on my list? Simple, if you have not chosen good gear, then getting a good deal, is no deal at all. I hope the above discussions will prevent you from purchasing the wrong gear, or falling for the marketing claims and purchasing unnecessary bells and whistles. If you can avoid those pitfalls, then you should have saved enough money to buy the right gear once.

What do you see diving in New Jersey?

Sunday, January 25th, 2009

The short answer is shipwrecks.

[singlepic=111,400,300,,left]
The Bow of the Chaparra

Here on the east coast we do not have the rocky shore and bottom found on the west coast. Our shore line is mostly sand, and for the most part the bottom is sand also. The continental shelf slopes out for 60+ miles before dropping off sharply. Sand and silt that washes out of our rivers and streams has deposited in this shallow area for thousands of years.

This sand does not provided shelter for fish or secure footing for large plants like kelp. The sand does provide a home for clams, scallops, and sand dollars, but the more interesting areas to dive are the shipwrecks.

There are an estimated 4000-5000 shipwrecks off the coast of New Jersey. (Many people are taken back by that statement.) Keep in mind that we have the port of New York to the north, and the port of Philadelphia to the south. Over the past 300 years there have been thousands of accidents in these waters. Further, during two world wars, the German submarine force spent a significant amount of time trying to stop the flow of supplies from the US to Europe. Many ships were sunk just miles off our beaches.

The older wrecks of wooden ships have been slowly eroded by the forces of nature. Storms, sand, rot, and marine invertebrates have nearly erase them. Still left are the stronger structural beams along with the anchor chain, and machinery used to lift it.

New steel ships quickly fall victim of rust. Many of these ships are now jumbles of steel rubble and hull plates strewn on the sandy bottom. Again stronger or reinforced portions of the ship hold up better with time. Engines, boilers, propellers, and pipes are often recognizable. Metals like coper, brass and bronze stand up better to salt waters corrosive effects.

Even in this state of decay, these wrecks provide shelter for marine creatures. Filter feeders like mussels, sponges and anemones attach to the wreckage for support. Lobsters and crabs burrow under the wreckage for protection. Schools if fish surround the wrecks. Some are looking for shelter, others are looking for food.

Monkfish, Round 1

Tuesday, January 13th, 2009

I retell this story regularly, and get a variety of responses.  As such, I thought I’d add it to the blog.    I really don’t recall the date, so let’s just say “long, long, ago in an ocean just off the beach”, I spotted my first Monkfish.  I don’t have my own picture of one, so I’ll have to reference a shot by Herb Segars. 

A little background for those of you unfamiliar with these creatures.  They are often called goose fish, or all mouth.  The latter is more a description, and an accurate one.   They are in the anglerfish family, and are mostly head and mouth.  They grow to over 5 ft in length, but 3 ft is more common.  They lie flat on the bottom with their belly down (like a skate or ray) but with the mouth facing up.   They are also well camouflaged.  When food (fish, lobster, crab, diver … ) comes within range, they quickly open their huge mouth which sucks water into their mouth and hopefully the prey comes with it. If they don’t completely swallow their prey on the first attempt, the rows of sharp teeth hold it in place for a second or third try.   Basically they are a large ugly eating machine.   The part of the fish that is not mouth, is mostly stomach.   On the other hand, the little bit of fish that remains is very good eating.

Stories are told of divers not seeing the fish, and kneeling on them, or putting their hands on them.  The shock factor having the sand come alive and try to grab you with rows of teeth, is the subject of many a dive tale.   Others tell of battles with the beast which often resulted in leaking drysuit or torn gloves.

Back to the story.   So here I am, novice diver swimming along spearfishing sea bass and totaug.  While making a pass over an old derelict lobster pot, I notice an odd shape in the sand.   It’s clearly not a fluke, and after a few seconds, I come to the conclusion that it’s a Monkfish.   Now what?  I’m not sure I want to argue with it, as it was larger than any fish I’ve encountered to date.  As I was the last in the water, and my dive is about done, I know Captain George should be down here somewhere hunting lobsters and getting ready to pull the hook.   I quickly found him and signal him over.

The ensuing conversation was all made with hand signals and gestures, but went something like this:
George:  Do you want him?
Dave:  I guess.
George:  Open your bag in front of him, and I’ll prod him into it.
Dave: OK, but I hope I don’t lose the fish in the bag.
Monkfish:   I’m not that dumb.   Stop putting that bag in my face.

One plan down.  Now what?  George bouncy castle for sale motioned for me to hand him my bag.  I obliged.  George opened the bag, then with one motion, he picked up the fish by the tail, and dropped it into the bag and closed it, before the fish had a chance to react.   He handed me the bag, waved goodbye, and went back to hunting lobster.

I could not help but laugh after hearing stories about these beasts.   My dive time was done, so I headed up the line.   Picture if you will, I’m holding the anchor line in one hand, and a bag of fish, including a very aggravated Monkfish in the other.  He’s got his mouth wide open, and I’m looking at rows of teeth that would easily poke holes in my drysuit.   My bag was one with a metal loop around the top that acts like an old style woman’s purse.   I finally figure out that sticking one end of the metal loop in his mouth will cause him to bite down, therefore preventing him from attacking me.

With a small degree of satisfaction, I board the boat only to find that I had avoided one attack, but fell victim of another.   Another endearing property of Monkfish, they generate slime. Lots of it.  I guess It’s either part of their camouflage, or stomach secretions from having it’s mouth open during the ascent.  Either way, I’ve been slimed!  My drysuit looked as if a giant had sneezed on me.  I put my catch bag in my cooler, then jumped back in water to clean the suit.

After everyone was aboard, we discovered that no one knew how to clean a Monkfish.    Fortunately, when we returned to the dock, George was able to find a commercial fisherman with the required knowledge, and hankering for lobster.   He made quick work of the task, and several of us went home with fillets in hand. I mean cooler.

In the end, Monkfish is good eating, but I must warn you, they are not for the timid.  It was a few years before I went for another one. They are not to be trifled with. They’re a mess to bring up, and a smelly mess to fillet.

Black Friday dive on the Independence II

Saturday, November 29th, 2008

With full boat, the Independence headed out for a Black Friday dive. Most of the divers were surprised at the number of other divers aboard. It was probably the result of many people having the day off work, and a favorable forecast. Everyone seemed happy to get in another dive for the season.

We were shocked to find that NOAA’s forecast was not exactly accurate. The front they were expecting to pass during the night had done so later than expected. We were faced with a swell from the southeast, and wind from the southwest. Given the conditions everyone agreed to changed the intended destination and headed to the Mohawk. The swell stirred up the bottom a bit reducing the visibility to 25 ft. The water temp had dropped from 54 degrees last week to 50 degrees. Some say the surface temp was a bit lower, but I did not take note of it.

By the time I splashed, some of the other divers had started to surface with some nice size tog and a few lobsters in tow. The report of 25 ft of vis, swell, and low light from the overcast sky made me decide to leave the camera onboard.

On my way down, I passed the remaining divers coming up the line. The bottom quickly came into view, but I had to give my eyes a few moments to adjust to the low light. The last time on this wreck the current had pushed me to the starboard side. This time it was to port. Now I could check out the rest of the wreck.

Frankie had us tied in next to the boilers. I started heading aft past the engine and stern, then doubled back toward the bow. From the last dive, the debris on the starboard side of the wreck had been mostly gear and cargo. Here on the port side, the debris bouncy castle for sale consisted mostly of hull. Ribs and strakes stood up out of the sand making navigation in the surge a bit of a timing issue. In the lea, there were small schools of fish taking refuge. Most of the larger sea bass and tog were hiding under the debris. Normally they are still active when the water is this warm, but they may have been waiting for more daylight to hunt for food.

Before long the bridge loomed up out of the center of the debris, an indication that I was approaching the bow. Here and there were balls of rope and netting swaying back and forth in the surge, almost looking alive in the hazy distance. The bow section was again surrounded by a school of cunners and juvenile sea bass. This time, I could not see from the base to the tip, and in the darkness I almost did not recognize where I was.

I started heading back to the stern. At several points I headed out into the sand to see if the small pieces of wreckage might contain lobster. I was repeatedly disappointed. Soon, I noticed that I could no longer hear the sound of bubbles in the distance. Figuring that the other divers were done their second dive, I headed to the line and just as I started to ascend, it went slack. I guess that means I’m the last one in, and it’s time to pull.

When I broke the surface I noticed that the swell had subsided, and wind seemed to have died down. We were soon headed back in much calmer seas, but the air temperature had dropped significantly. Chalk up another one for NOAA, but was still a great day of diving.
