Go deep, stay long

Manatee calf looking for attention

Val and I were invited on a trip to Florida, including a Manatee dive in Crystal River. As it worked out, I did have some time off, so we packed our gear and headed down. Val was going to stay a few days, for the Manatee dive, after that, I was planning to stick around for a cavern/cave class.

Packing went smoothly, except for the snowstorm that covered the area the day before the trip. Most of the roads up here were dry with some salt for good measure. On the trip down we stopped over with our friend Grace in Durham. Their roads were not cleared as well, and the drivers were not accustom to snow. It was not a pleasant situation, but with only minor delays we were back on the road the next morning.

We arrived in Crystal River a bit later than expected, but were up and ready for the dive the next morning. Dive gear, camera gear, and all weather gear packed and ready, we headed out.

This was our first time diving with Manatees. The boat rental required us to watch a video concerning the regulations around Manatee interaction. Bottom line, nothing can prepare you for the actual dive! Becky had invited a group of experienced divers. We hit the water expecting to see a few dozen Manatees. I’m not sure if it was the cold weather, or something else, but there were a few hundred Manatees in the area.

We anchored in a small tributary with river water, and spring water running past a Manatee Sanctuary. Within the roped off sanctuary, there were a dozens of resting Manatees. Back in the springs, the sandy bottom was covered with them. We were all snorkeling on the surface looking to see if any were interested in interaction. Many were resting, but others would swim right up to us.

At first, it’s a bit unnerving to have a 1200lb animal swim up to you. These creatures are 5-6 times our size. It makes you think for a second. Then they roll over and want their belly rubbed. Ok, not so intimidating. The juveniles (calf) are more curious than the older adults, but both were curious about us as divers. I’m not sure why, but my camera seemed to draw their interest. Some would swim up and interact. Several would swim up, play for a bit, and then swim away. Many came back again and again.

After I filled up my still cameras memory card, I switched to the video camera. It was both fun and enlightening interacting with these gentile creatures. As usual, they had to drag me from the water, since I was having so much fun.

If you ever get a chance to dive with Manatees, I highly recommend it. Take your time, and let them come to you. They are both fun and engaging.

It certainly has been difficult to get out diving this fall. However, the few times we were able sneak out, the diving was fantastic. This Sunday we headed out to the Resor with a jam packed boat. Clearing the inlet we had nearly flat seas, and just a breath of a breeze. With the early start, the sun was just rising. We all kept our fingers crossed that the conditions would hold, since NOAA was calling for the wind to pick up a bit in the afternoon.

By the time we reached the wreck, the sun was a bit higher in the sky, and the conditions were still flat. The surface water was a nice Caribbean blue. Dropping down the line it was clear that there was a good current to the east. This made going a bit slow, but we were soon tied in.

While working with the line, shadowy figures kept appearing in the distance. At first I thought the dogfish were back, but it turned out to be bluefish. We saw them inshore last week. Now there was a school buzzing around us on the Resor. Ever few minutes a few of them would dart by. Down on the sand, there were large fluke and flounder almost side by side. Normally we see one or the other, but here the flounder were hunting while the fluke were resting. Both scurried off when approached. Large tog are always around this wreck, and this was no exception. I spotted a few small lobsters, and one good size one with eggs.

I was nearing my turn time when I spotted a nice new Danforth with a long chain. At least I was not going up empty handed. It turns out that the current and the wind were not aligned, and I spent my deco holding my reel in one hand (attached to the Danforth and lift bag) and the shot line in the other. I was just hoping other divers would not get caught in the line.

My hunting efforts had been thwarted, but many others came up with lobster, tog and some nice size pollack. There were various reports of giant lobsters, deep in the wreck, well out of reach. A few folks had ventured out into the sand for scallops, with varying degrees of success.

All in all it was a great day of diving with 30-40 ft of vis and 65 degrees top to bottom. The wind had picked up as we started to head in, but it was still a comfortable ride home.

Independence II

The short answer is: not having your camera, but that’s a story in it self. Today’s dive was to the U-869 AKA the U-who. The Independence was filled with quality NJ divers, but most of them had never been on this wreck. I was diving with a student, Tom, who was also visiting the wreck for the first time.

We headed out early in the flat calm seas left in the wake of Hurricane Bill. We made good time to the wreck. Bill and Brandon went into tie in. It often takes a few minutes since you never do anything fast in 230 fsw. I helped the first group of divers get in, then we geared up. After buddy checks, we reviewed the plan one more time, then splashed.

The surface temp was high 70s, no current, and the water was very clear. Brandon and Bill were hanging, and Brandon took the opportunity to snap off a few of his great shots. If I were not with a student, I would have paused a few moments to give him a model, but Tom was dropping fast, and I wanted to catch up. We passed other groups of divers on the way. Many had lobsters in their bags.

The line was completely slack all the way down to the wreck. No current at any level. This is unusual out here. Often the current changes directions at different levels. There was nothing, anywhere. It was obvious that there were many layers. You could see them as you passed through. The vis would change, and you could see the water go from cloudy to clear to cloudy. Some of the layers were thermoclines, and the temp started dropping. Below 120ft we felt the drop down to 46 degrees. After a few minutes it started to get dark, and I switched on my light. Now I could easily signal my position, and could see my buddy. Tom started slowing his decent. I’m not sure if he was waiting for me, or if he just needed more time to clear his ears. Either way, I caught up.

My gauges indicated that we were within 50 ft of the wreck, but nothing was coming into view. We continued to drop. The faint glow of a strobe lit up the area. The vis had dropped to 10 ft, and the wreck suddenly appeared below us. The chain was wrapped around a cylinder on top of the wreck.

With the short vis, I immediately reached from my reel. I’ve never run a reel on this wreck before, but I did not want to miss the line with a student in tow. Given the depth and conditions, I was concerned that Tom might be nervous. This proved completely unfounded, as he soon grabbed a lobster and put it in his bag. Not that we were here for lobster, but when they are right there, what do you do?

Given the conditions, we swam slowly along the wreck trying to identify anything we could. We reached the Bow, and dropped down the side to the sand 230ft. This was perfect timing for our dive plan as it was time to turn around. We returned slowly to the line and arrived ahead of schedule. With a few minutes left we continued aft, and found that we were tied in just ahead of the break. We quickly inspected the blast area, which contains a jumble of ripped and torn steal, then doubled back to the line.

At this point, I was happy I had run the line. The strobes on the anchor were no longer visible. We were only a few feet away, but could see nothing. For a few seconds your heart skips. Replay your steps. Ok, there it is. I was not so concerned for myself, as my gas plan left me lots of reserve. I never know how conservative a student is with there gas estimates. We reached the line with a minute or two to spare, and signaled UP.

The long slow assent starts. The initial stops are still cold, and now that we are not swimming, the cold can be felt. Clearing the 100 ft stop brought the temp up to 55. That’s a huge change and it felt great. Soon we could see other divers above us. Those we passed on the way down the line, were now hanging at their shallower stops. Above 50 ft the temp jumped back into the 70s and vis was fantastic.

Tom had run his numbers with the VR3, while I was running V-planner. As we discussed, I would have longer deeper stops, and shorter shallow stops. This was more evident that I realized. Most of my early stops, I was 10-20 feet below him. At 40 ft we matched up, then at 20 ft he indicated 10 minutes as I was cleared for the surface.

At some point in this evolution, we were hanging with another four divers around the 20 ft stop. Two divers had ascended the anchor line, while the rest of use went up the Caroline line. Time passes slowly, and we were just hanging there for our stops to clear. I looked down and noticed a very large object moving in the water below us In the clear water, I could easily make out the features of a very large shark. The nose had the distinct features of a basking shark. From above we could not see the mouth, but the snout was unmistakable. I looked to my fellow divers who were transfixed on their gauges. I got their attention, and pointed out the shark. It swam slowly around the Caroline line below us, then doubled back to the anchor line. It swam around the lines in a figure eight, then swam slowly off into the distance. Since it swam between the lines, we knew it was only about 20 ft below us. Comparing its size to the divers on the bow line, I estimate it was a minimum of 20ft. I’ve seen Basking sharks before, but never this clearly. It was an awe inspiring sight!

While we were really psyched at the incredibly cool experience, I was chastising myself for not bringing my camera. Given I was with a student, on a deep dive, I did not want the extra task loading. I was planning on grabbing it after the dive, and snapping a few shots of the other divers entering and leaving the water. Well, I did not have it now, and was quite disappointed! We spent the rest of our decompression looking around for the shark to return, or perhaps one of its school (as Basking sharks are know to swim in schools). No such luck.

Once on the surface, we did talk about the shark, and some asked what type it was.  I’m sure it would have been a much more heart pounding experience for those that did not know. I did grab the camera, and swam around the boat taking a few shots. Captain Dan, and Danny jumped in for a dive and to pull the hook. The sea was flat calm, with no current. It was an enjoyable wait just floating in the water.

Before long we were underway for the long trip home. It was a great day, and many will tell the story of seeing a huge basking shark.

It’s been a few years since I’ve had the opportunity to do a Northeast twilight dive. Some of our deep dives seem like night dives, but a twilight or night dive on a shallow wreck is a different story.

As we approached the wreck the sun was getting ready to set behind us. This was a low lying wooden wreck, so Bill looked carefully for a good piece to drop the hook on. By the time I cleared 20ft my light was the only thing visible before me. On the bottom, the line was right on top of a large rib. We were soon tied in, and it was time to reconnoiter.

Given this was my first dive on this wreck, my standard practice is to look around first, then decide on a plan of action. Within a few feet of the line, the telltale signs of lobster were evident. Here, there, everywhere. They were not coming out yet, but there were quite a few in some deep holes. Sea bass were everywhere, and some were quite large. Tog and ling cod where here and there. Sea Robins were all over the sand. Even a nice Conger eel was swimming about freely. It was bit startled by my light. Swimming up the main rib, there were also signs of fluke, and large ones. All of this was very bad, since my weapons were on the boat. After coaxing a 22 inch fluke into my bag, I headed to the surface for reinforcements.

The remainder of my short dive was spent mapping out the wreck in my mind, and collecting fluke along the way. Like most wooden wrecks, there was a nice chain pile at the bow. Many fish and lobster were entrenched here. Some low lying sections stood just a few inches off the sand. Here, Sea bass darted in and out in response to my light.

Back on the surface, the sun had set, and Bill was getting ready to jump in. As the divers came up they all agreed that this was a great dive, and we should do it again. At this point Captain Dan regretted leaving his gear at home. After a short while, we could tell Bill was at his safety stop by the aura of his HID light: 20-30 foot arcs of light. It’s kind of eerie to see the water lit this way at night.

If you’ve never done a night dive here in NJ, I strongly suggest giving it a try.

Many divers live in tropical climates, or only dive when they travel to these climates. Up north they are often called Caribbean divers, or blue water divers. I prefer warm water divers, as many travel beyond the Caribbean, and blue water is often used in reference to very deep water.

Diving under these conditions can be both exciting, and relaxing! The scenes of tropical reefs and colorful fish are beautiful and serene. The diving is often easy and at many resorts it’s supervised. This is a great place for beginning divers to practice their new skills, and enjoy the wonders of underwater world.

Gear:
We previously talked about basic SCUBA gear, so now let’s add a few items for tropical diving.

Exposure protection:
This will be the major consideration. There are a few variables here:
Water temperature
Air temperature
Your bodies reaction to cold
How many dives are planned

Read the section on Exposure Protection for more details

Signals:
Tropical diving is often done around small islands. Sometimes in strong current. Separation for the boat is a real possibility, and signal devices can be real life savers! If your planning a drift dive, then will need a marker to let the boat know where you are. A visual aid like an SMB is ideal for both situations. Also a audible signal like a whistle, or Dive Alert can get the attention of the dive boat when you’re hard to see. Both of these can be easily carried in a BCD pocket.

Skills:

Buddy Skills: With all the fascinating beauty of the tropical reefs, it’s all too easy to become distracted and lose contact with your buddy. Try to stay within about 10 ft, and don’t forget to check on them regularly.

Depth Control: The clear water can be very deceiving. Remember objects appear closer under water. We can easily go deeper than planned, and run into issues with gas management, or decompression. Keep an eye on your gauges!

Buoyancy Control: Coral reefs are fragile environments! A single kick can kill an organism that has lived for 100 years. We as divers are fascinated by this spectacle, but we must protect it from ourselves. Work on your buoyancy. Practice it whenever you have a chance.
