Jaclyn goes to the Caribbean
After spending three weeks on a live aboard dive trip through the the Winward Islands I came back with these photos. My trip started in Grenada and from there we sailed up through St. Vincent and the Grenedines to St. Lucia all the while diving multiple dives a day. I lived with nine other teenagers on a 46-foot catamaran. It was definetly the best trip of my life. Every place we went to was more beautiful then the next and the diving was absolutly gorgeous. The program was through Broadreach and it takes teenagers on dive trips all around the world. I became a certified Rescue Diver in those three weeks and also recieved six specialties. There's no doubt in my mind that I wouldn't choose another trip like this and I completely recommend them. I fell in love with diving because of this and it is now something I will continue to do for the rest of my life.

Invasive Species in Lake Michigan
We all know about zebra mussels but there are other invasive species in Lake Michigan. This article for the Tribune discusses some of the species and the changes they are causing.
Underwater, a disturbing new world
A Tribune team follows researchers to the bottom of Lake Michigan as they try to explain the rapidly shifting ecosystem

But as the three researchers wearing scuba tanks and lead weights drop through the water, the landscape of rounded stones 30 feet below is disturbingly full of strange, new life.
In just a few years, the gravel and white boulders that for centuries covered the bottom of Lake Michigan between Chicago and the Door County, Wis., peninsula have disappeared under a carpet of mussels and primitive plant life.
The change is not merely cosmetic. In the last three years or so, scientists say, invasive species have upended the ecology of the lakes, shifting distribution of species and starving familiar fish of their usual food supply.
Signs of the shift have been hard to ignore. Mats of dead, smelly algae wash ashore on Lake Michigan from
Multiple strains of E. coli bacteria and botulism spores thrive in the new underwater garden, leading scientists to suspect they are contributing to beach closings and the widespread deaths of migratory birds. Meanwhile, fishermen notice the lake trout, salmon and whitefish are getting skinnier each season.
The rapid shift has researchers scrambling to understand what is happening and how widely the impact will be felt.
"The lake is changing faster than we can study it," said University of Wisconsin-Milwaukee researcher Harvey Bootsma, whose small team of researchers hunts explanations from this new lake bottom in weekly dives off the Wisconsin shore.
Adaptation possible
Some ecologists and fishery managers say the
"We don't necessarily know all the impacts, but we know enough to know that they are being catastrophic," said Cameron Davis, president of the
None of the key species leading the change—mussels, algae and round gobies—are new arrivals. The zebra mussel famously invaded
But in the last handful of years the quagga has taken off with alarming speed, exploding across the lake floor.
While zebra mussels like to attach themselves to rocks and man-made structures, the quaggas can colonize sandy bottoms deeper in the lakes. Between them, the species filter lake water ceaselessly, making it so crystal clear that light can penetrate far deeper than before.
That change has allowed a native species of algae called cladophora to run rampant. It now can grow in 30 feet of water, twice as deep as a decade ago, and its waving tendrils cover vast offshore areas.
Round gobies, an invasive fish species from the
Together, these species have not only altered the clarity of the water but also devoured and filtered out the nutrients that used to sustain plankton and shrimplike diporeia at the base of the lake's food chain, starving what larger fish are left.
To be sure, the
By the 1950s, the most important fish in the native food chain—lake trout, ciscoes and spiny sculpins—were nearly gone in the lower lakes and severely reduced in Lakes Michigan and Huron. Still, scientists say perch, salmon and the alewives on which they foraged formed a relatively stable ecosystem until the invasive mussels began devouring key microscopic nutrients.
"Now all the forage fish are way down in Lake Michigan and Lake Huron," said Henry Vanderploeg, a
It's possible fish will weather the changes. Fishermen have caught lake trout that had gobies in their stomachs, and smallmouth bass in

How to Buy Dive Gear
Buying Dive Gear is confusing.
At Sea Lions Dive Center we want you to be as informed as you can be when you decide to make your purchase.
We have prepared a number of links to articles on how to choose various equipment and we have a special web page that may help. Those links are listed in the box in the upper left hand corner of this blog.
If we can do some further research to help you out let us know.
We understand you may not buy all your dive gear from Sea Lions but we want to be the Center of you Diving activity. Visit our sites and our Dive center and tell us what we can do to make your diving experience better.

High pressure tanks including SCUBA tanks must be visually inspected annually and must be hydro tested every five years. This is not a Sea Lions Dive Center requirement it is required by law. We had a customer in the dive shop recently who insisted we fill his tank without a current visual. When we refused he became quite vocal and said that we were trying to cheat him and began making other abusive and loud remarks regarding our prices. He said he could buy dive gear for half our prices at a local sporting goods store and on the Internet. We asked him to leave and his parting comment was “an informed customer is your worst enemy.”
In fact a “misinformed customer is our worst enemy.” We do our best to offer products and services at competitive prices. The sporting goods store – who has since discontinued selling dive gear – sold only low end regulators to customers only interested in price. They offered no expertise, no help selecting gear, no service and no airfills. We had a customer bring in one of these “bargain regulators.” The reg was in pieces and the sporting goods store could not even assemble the parts.
Regarding the Internet, dive store employees, including those of us at Sea Lions get very defensive when people talk about buying gear on the Internet. The internet sites skim the cream and offer the highest margin items at a discount but do not offer the lower margin items such as service and air fills.
We know you look at the Internet… so do we. Buying dive gear on the Internet is a crap shoot. Many times you will purchase the gear and it will work out for you. But when it goes bad it can go real bad. Many of the Internet sites are not authorized dealers. We sell Uwtech Computer in part because they we feel they have the best warrantee in the industry. If you buy Uwatech or ScubaPro on the Internet you do not get that warrantee no matter who you buy it from.
If you find that you would like to support our effort to offer local services but cannot resist the Internet please visit our dive gear site. You will find helpful articles on purchasing dive gear and you will also find links to Internet sites that sell dive gear. If you enter these sites through the link on our web page when you purchase we will receive a small commission but it will not increase your cost.
I apologize for the length of this rant but it is a sensitive and important issue.

Lionfish in Atlantic
Original link http://www.msnbc.msn.com/id/26184738/
updated 4:55 p.m. CT, Wed., Aug. 13, 2008
SAN JUAN, Puerto Rico - A maroon-striped marauder with venomous spikes is rapidly multiplying in the Caribbean's warm waters and even off the East Coast — swallowing native species, stinging divers and generally wreaking havoc on an ecologically delicate region.
The red lionfish, a tropical native of the Indian and Pacific oceans that probably escaped from a Florida fish tank, is showing up everywhere — from the coasts of Cuba and Hispaniola to Little Cayman's pristine Bloody Bay Wall, one of the region's prime destinations for divers.
Wherever it appears, the adaptable predator corners fish and crustaceans up to half its size with its billowy fins and sucks them down in one violent gulp.
Research teams observed one lionfish eating 20 small fish in less than 30 minutes."This may very well become the most devastating marine invasion in history," said Mark Hixon, an Oregon State University marine ecology expert who compared lionfish to a plague of locusts. "There is probably no way to stop the invasion completely."
A white creature with maroon stripes, the red lionfish has the face of an alien and the ribbony look of something that survived a paper shredder — with poisonous spikes along its spine to ward off enemies.
Scale of invasion is unique
The invasion is similar to that of other aquarium escapees such as walking catfish and caulerpa, a fast-growing form of algae known as "killer seaweed" for its ability to crowd out native plants. The catfish are now common in South Florida, where they threaten smaller fish in wetlands and fish farms.
In Africa, the Nile Perch rendered more than 200 fish species extinct when it was introduced into Lake Victoria. The World Conservation Union calls it one of the 100 worst alien species invasions.
"Those kinds of things happen repeatedly in fresh water," Hixon said "But we've not seen such a large predatory invasion in the ocean before."
The lionfish so far has been concentrated in the Bahamas, where marine biologists are seeing it in every habitat: in shallow and deep reefs, off piers and beaches, and perhaps most worrisome, in mangrove thickets that are vital habitats for baby fish.
Some spots in the Bahamian archipelago between New Providence and the Berry Islands are reporting a tenfold increase in lionfish just during the last year.
Northern Caribbean islands have sounded the alarm, encouraging fishermen to capture lionfish and divers to report them for eradication.The invasion would be "devastating" to fisheries and recreational diving if it reached Puerto Rico and the U.S. Virgin Islands, according to Eugenio Pineiro-Soler of the Caribbean Fishery Management Council.
"I think at the best they will have a huge impact on reef fish, and at the worst will result in the disappearance of most reef fish," said Bruce Purdy, a veteran dive operator who has helped the marine conservation group REEF with expeditions tracking the invasion.
Purdy said he has been stung several times while rounding up lionfish — once badly."It was so painful, it made me want to cut my own hand off," he said.
Researchers believe lionfish were introduced into the Atlantic in 1992, when Hurricane Andrew shattered a private aquarium and six of them spilled into Miami's Biscayne Bay, according to the National Oceanic and Atmospheric Administration.
Biologists think the fish released floating sacs of eggs that rode the Gulf Stream north along the U.S. coast, leading to colonization of deep reefs off North Carolina and Bermuda. Lionfish have even been spotted as far north as Rhode Island in summer months, NOAA said.They are not aggressive toward humans, and their sting is not fatal. There are no estimates so far of tourists who have been stung. But marine officials say swimmers will be more at risk as the venomous species overtakes tropical waters along popular Caribbean beaches.
The slow-moving fish, which measures about 18 inches, is easy to snare, though lionfish swim too deep for divers to catch in nets — a common method of dealing with invasive species.
Looking for lionfish predator
So researchers are scrambling to figure out what will eat the menacing beauties in their new Caribbean home, experimenting with predators such as sharks, moray eels — and even humans.
Adventurous eaters describe the taste of lionfish fillets as resembling halibut. But so far, they are a tough sell. Hungry sharks typically veer abruptly when researchers try to hand-feed them a lionfish.
"We have gotten (sharks) to successfully eat a lionfish, but it has been a lot of work. Most of our attempts with the moray eel have been unsuccessful," said Andy Dehart of the National Aquarium in Washington, who is working with REEF in the Bahamas.
One predator that will eat lionfish is grouper, which are rare in the lionfish's natural Southeast-Asian habitat. Scientists are pinning long-range hopes on the establishment of new ocean reserves to protect grouper and other lionfish predators from overfishing.
Hixon said there is some evidence that lionfish have not invaded reefs of the fully protected Exuma Cays Land and Sea Park, a 176-square-mile reserve southeast of Nassau. But unprotected locations in the vast archipelago are more vulnerable.
Containing the spread of the lionfish is an uphill fight. As lionfish colonize more territory in the Caribbean, they feed on grazing fish that keep seaweed from overwhelming coral reefs already buffeted by climate change, pollution and other environmental pressures.
Dehart said: "If we start losing these smaller reef fish as food to the lionfish ... we could be in a whirlwind for bad things coming to the reef ecosystem."

Despite the many locations to obtain scuba diving certification in the region, most new divers postpone their first dive until they can travel to more tropical climates. However, regional dive shop owners think that the lakes are vastly underrated and new divers often miss out on the opportunity to explore the shipwrecks, remnants of history frozen in time.
“It’s eerie to see something that you’re not supposed to see underwater and strange seeing something so out of context,” said Ralph Naruscewicz, an owner of D.D.

“I have newly certified people go out and do a dive and they don’t think they’re going to see anything,” he said. “But they see the wreck, they see the artifact, they get back on the boat, and you can’t stop them from talking for the next half an hour because it is the most thrilling experience.

Lupton, Sharon Cook and others pulled on wet suits, fins, masks and air tanks to swim down to the bow section where two large iron anchors landed on the sandy bottom, entwined in front of long sections of the wooden hull. The windlass, which would have pulled up the anchors, ended up next to the planks, not far from a portion of the hull that looks like a skeleton with ribs sticking up in the green water.
The shipwreck was discovered in 1989 by Harry Zych, who was awarded ownership a decade later after a long legal battle.

Lake Wazee
The depth of Lake Wazee make it a scuba diver's paradise. |
By Gregg Hoffmann Special to OnMilwaukee.com E-mail author More articles by Gregg Hoffmann |
Published Aug. 3, 2008 at 5:04 a.m. |
If you want to say you've gone swimming in the deepest lake in Wisconsin, take a dive into Wazee Lake in Jackson County.
Wazee Lake, east of Black River Falls, is 355 feet in its deepest hole. That's more than 100 feet deeper than Green Lake. Of course, the folks near Green Lake will argue that their lake is a natural waterway while Wazee is a restored quarry.
Scuba divers and others don't really care about that distinction. Most will tell you that Wazee is the deepest and clearest lake in the state, and they love it.
The name Wazee means "tall pine" in the Ho-Chunk language. You can see where the name fits the lake and recreation area around it, since pine trees are plentiful. The Black River State Forest, in fact, is near Wazee and offers a variety of hiking and other trails.
Wazee was formed artificially, after being used as a quarry for taconite mining between the mid-1960s through April 1983. The quarry produced about 850,000 tons of taconite pellets each year.
The mine closed in 1983 as a result of a crash of the domestic steel markets in the United States. When the mine was in operation, pumps removed about 800 gallons of water per minute from the quarry. Once these pumps were shut down, the quarry began filling with water.
The lake, now part of a county park, is a prime scuba diving destination because of its deep, clear water. Visibility averages between 30 and 40 feet during the summer months.
There are also visible remains of mining operations underwater, such as roadways used for hauling equipment. Some features have been added to the lake, such as underwater platforms for training divers and fish cribs to improve habitat for the fish. Fish species within the lake include rainbow, brook and brown trout, bluegills, suckers, catfish, walleye, warmouth and smallmouth bass.
Because of the depth, Wazee's water is cold. It runs from approximately 70 degrees surface temperature to 40 degrees below the thermocline. The thermocline depth varies during summer, but averages about 30 feet.
Divers who venture to greater depths will encounter a second thermocline at approximately 60 feet where the temperature drops to a chilly 34 degrees. Use of a quality dry suit (with proper training) is recommended for deep diving in the lake.
If that isn't cool enough for you, ice diving has become very popular at Wazee.
Other activities exist in the rec area for additional enjoyment. Many miles of hiking and gravel surfaced bicycle trails wind through a mosaic of prairie and forests. Several scenic overlooks are currently under construction as well as improved picnic and sanitary facilities. Construction of a large beach and boat launch complex was completed in 1996.
Wazee is not the only popular quarry lake in the state. Red Granite Quarry Lake in Waushara County is listed as the third deepest lake in Wisconsin with a maximum depth of 163 feet.
Discovery of red granite at the central Wisconsin hamlet of Sand Prairie in the 1880s sparked a mining boom that brought skilled stonecutters from Europe to settle the area. Granite paving blocks from the quarry were used in streets as far away as Chicago.
When concrete and asphalt became the popular choice for paving, the site closed in the 1920s. Now filled with a 7-acre lake, the quarry was designated a Red Granite village park in 1995, and is used by scuba instructors for deep-water diving certification and by tourists and residents for other recreational activities.
Lohrville Quarry Park, also in Waushara County, is listed as the fifth deepest lake in the state at 120 feet. It took offers great diving, swimming and other recreation. Brillion in Calumet County also is home to a quarry lake.
Closer to Milwaukee, you can find Quarry Lake Park in Racine. Again, scuba divers use this lake and swimmers and sun bathers also love the expansive multi-level terraced beach.
Once a limestone quarry, this park has been transformed into one of the finest outdoor swimming and beach facility in the area. Quarry Lake park features an 18-acre lake, picnic areas with grills, a large air-conditioned beach house with changing rooms, lockers, concessions, lavatories and showers.
Scuba divers must be certified and pay a registration fee to enter and explore the depths of the Quarry Lake. A daily entrance fee is charged during the swimming season.
Sheboygan Quarry Lake, an 18-acre lake with depth of about 45 feet also is popular with divers. Harrington Beach State Park, which has been featured in OnMilwaukee.com before, has a quarry lake as well as a wonderful Lake Michigan beach.
There are other quarry lakes around the state. You can find out more about them at www.dnr.state.wi.us.
