Do you ever see sharks?

Sunday, January 25th, 2009

Yes, all the time. The real question is “are they a danger to SCUBA divers?”

The most common, or plentiful, shark in the Atlantic only grows to a length of 4-5 feet (more commonly seen at 3 ft). They are called sand sharks or bouncy castle for sale Spiny Dogfish. They can be seen around the wrecks either alone, or in small groups. Are they a threat? No. I don’t believe there has ever been an unprovoked attack on humans.

Cute little shark.

Do we see other sharks? Yes, but far less frequently. Further off shore we will occasionally see basking sharks. These are filter feeders, and no threat, but with their large size, they startle you at first. Other divers have reported seeing Blue sharks, and Mako sharks.

Some things to keep in mind. The incidence of shark attacks on divers is very low. Most shark attacks are in shallow water in the surf zone (beach), with limited visibility. Most divers are in deeper water, with good visibility. In recorded history, there have been only a hand full of attacks in New Jersey. None of these have been on divers.

What do you see diving in New Jersey?

Sunday, January 25th, 2009

The short answer is shipwrecks.

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.

How deep can you dive on SCUBA?

Wednesday, January 14th, 2009

When people first hear about SCUBA diving, many ask this question.   My standard response is “to the bottom”.   While I am joking a bit, unless you’re doing a wall dive, this is usually the case.

Part of the answer depends on the location of the dive: off the coast of New Jersey, the bottom slopes gently for the first 30-50 miles.   Shortly after this we hit the Continental shelf, commonly called the Canyon.   Here the depth drops sharply to several thousand feet.   Obviously our diving is on the gently sloping bottom.

About 3 miles off the beach, the depth averages about 60ft.  After 20-30 miles, there are some great wrecks in 130 ft.   The bottom slope does vary from place to place.   There is narrow trough cut by the Hudson river commonly called the Mud Hole. Inflatable Water Slide It is deeper than the surrounding area, but the outflow of the river makes the conditions more challenging.

The rest of the answer depends on the diver’s experience and training:

Novice divers should stay shallower than 60ft, until they develop the skills and comfort in the water necessary to go deeper.

Advanced divers go between 60 and 130 ft.  At this point they carry additional safety equipment necessary to perform these dives.

Technical divers go beyond the 130 ft range down, sometimes in excess of 300 ft. These divers have spent years training and practicing for these dives.  They carry redundant gear and practice techniques to survive equipment failures.   Many famous shipwrecks are in this range: the Andrea Doria, the U-869, the Black Sunday wrecks including the S.S. Carolina.  These all fall in this range of technical dives.

How deep do I personally go?  Well, I teach Technical Divers.  While I enjoy spearfishing and photography in the 50-130 range, we can often be found diving in the 180-250 range.

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.

The Gulf Trade on November 9

The top of the wreck, covered with mussels and surrounded by fish

Sunday we headed out to the stern of the Gulf Trade. The ship was a 430 ft tanker owned by (who else) Gulf Oil. When she was torpedoed in 1942, she broke in two. The stern section sank in 85 ft of water about 10 miles off Island Beach. The bow section floated closer to shore before sinking near Barnegat inlet. As a hazard to navigation, it was leveled.

The superstructure of the wreck still has about 20 ft of relief. Brandon tied us into the top making it an easy point of reference. On the top deck cunners, tog and sea bass swim in and out of the holes in the deck, nibbling at the mussels that grow there. Inflatable Water Slide A few feet away are two large boilers, still standing up the sea’s destructive forces.

Mooring bits and scup

Once off the superstructure, the debris field stretches out over a wide area. Here small pieces of debris provide hiding places for lobster and fish. Still within the shadow of the wreck, a pair of large mooring bits stand upright in the sand. A large school of scup surrounded the area. The school prevented my camera from focusing on them.

Over by the boiler was another visitor from out of town. A butterfly fish darting around the wreck, looking very out of place. This is the third one I’ve seen in as many days of diving.

Engine

Before long Brandon showed up and we started taking pictures of the large engine and boilers. Along with other bits and pieces of the wreckage that caught our eyes. A large trigger fish swam by but was not waiting for his picture. However, the dog fish that swam by a few minutes later came within a few inches of the lens.

With the great conditions, it was hard to end to dive. I just have to figure out how to bring the camera and the pole spear on the same dive. No task loading there!
