Space-Age scuba suit enables divers to go deeper

Published

on

A space-age scuba suit that enables scientists to dive and stay beneath the water’s surface at depths of 1,000 feet or more will have its first test this summer in the ocean off Nantucket.

The suit, known as an Exosuit, is on exhibit until Wednesday at the American Museum of Natural History in Manhattan. Scientists there say it will bring ocean exploration to a new level, going beyond the mini submarines that have been used to explore deep unchartered waters to collect marine life from its natural habitat.

The 530-pound aluminum alloy suit has rotary joints at the hands, elbows and knees and a bubble helmet mask. The suit’s handgrips enables scientists to touch and grab marine life and provides a 50-hour life-support system with communications with a surface vessel.

“For the first time, I will be able to get out into the water and experience marine life and actually touch it,” said John Sparks, 50, a curator at the museum’s ichthyology department. Sparks, who is not a diver but has been training for the excursion, said he is especially excited about the suit’s foot power thrusters that will help maneuver him through the ocean waters.

Scientists this summer will test an Exosuit off the coast of Nantucket where waters plummet 10,000 feet. “This is blue water. There is no bottom,” said Michael Lombardi, 31, the museum’s diving safety officer and marine biologist who will also test the suit.

“We are at a crossroads of diving technology,” said Lombardi. “This is a form fitting space suit. You are in a shell with all this technology that works with you.”

Scientists hope to gather a new jelly fish species with a visible luminescent light they hope to reproduce for medical research in helping to track cell movements in the human body.

Using Exosuit to collect these bioluminescent species in their natural environment will allow scientists to freeze them for research at the lab.

“Our access to these deeper waters [up until now] has restricted our ability to investigate the behavior and flashing patterns,” said Sparks. Before Exosuit, divers could only see them when they emerged in shallow waters, when their luminescence is not as intense.

Now with Exosuit, scientists can study them for several hours watching and documenting their lighting patterns with video and high-definition images, all in their environment, said Sparks.

Ultimately, the suit will give divers the chance to work in some places where no human has gone before. “Underwater exploration gives opportunities to be the first person in that environment and that is a very humbling experience,” Lombardi said.

Diving with… Ana and Miguel, Siladen Resort & Spa, Indonesia

Published

on

In this ongoing series, we speak to the people who run dive centres, resorts and liveaboards from around the world about their businesses and the diving they have to offer…


What is your name?

Ana and Miguel

What is the name of your business?

Siladen Resort & Spa

What is your role within the business?

Co owners and General Managers

How long has the business operated for?

Almost 20 years.

How long have you dived for, and what qualification are you?

Miguel has dived since 1993 and Ana has dived since 2002. We are both Open Water Scuba Instructors.

What is your favorite type of diving?

We love all dive types, especially wall diving for the wonderful corals and looking out into the blue wondering what other animals will come up next. But as an UW photographer and videographer we both love critter hunting in the sandy slopes. We are both very fond of night dives as we always find interesting animals and different behaviour.

If you could tell people one thing about your business (or maybe more!) to make them want to visit you what would it be?

We have a wonderful location in the heart of Bunaken National Park and we have an amazing team that provides the best service to each guest. We are a fun dive resort; we constantly strive to be as sustainable as possible and safety is our number one priority. If you like sea turtles and beautiful coral reefs you cannot miss this area for diving or snorkelling.

What is your favorite dive in your location and why?

If we have to choose one wall we would say Mandolin as it has beautiful and healthy corals with a wonderful and shallow reef top. We love to search for turtles in the overhangs, look for long nose hawkfish in the black coral bushes, admire the schooling snappers, and spend a long safety stop on the coral gardens on the top that are full of anthias. For critter hunting and night dives we both love Bolung. Here we can find frogfish, ghostpipefishes and nudibranchs, plus at night we often find decorator crabs, octopus and even stargazers on its white sandy slope.

What types of diving are available in your location?

There are very shallow coral reefs surrounding all five islands within Bunaken National Parkpark — beyond the shallow reef, the seabed drops away very quickly, forming the beautiful walls that Bunaken is famed for. Many of these walls are vertical with huge caverns and overhangs, however some are more gentle slopes that allow more reef building corals to form. On the North Sulawesi mainland there are black sand sites that allow amazing muck diving. Close by, we also have white sand sites, which offer some beautiful coral reefs and gentle slopes. There is even a fairly intact (entirely sponge encrusted) wreck within easy access of the resort.

What do you find most rewarding about your current role?

Working together in a dive resort that welcomes divers and snorkellers from around the world and sharing with them our passion for diving, snorkeling and uw photography and video is a great pleasure. Besides we have the privilege to dive and snorkel at world class sites every week.

What is your favorite underwater creature?

We both love cephalopods in general for their intelligence, capacity to camouflage, change colors and patterns…. We are fortunate enough to have many encounters with cephalopods in this area, from the tiny bobtail squid to the wonderful broadclub cuttlefish, the flamboyant cuttlefish, squids and Ana even filmed reef octopus mating. We could watch cephalopods for ever. And although we see them often, Ana has a soft spot for turtles.

As a center what is the biggest problem you face at the moment?

The biggest problem we all face as divers and nature lovers is climate change and pollution. We need to work on these issues locally but even more importantly we need to address these issues worldwide.

Is your center involved in any environmental work?

Yes, we clean our beach daily and we organise very frequent island clean-ups. Not only do we clean this area, but we also separate the garbage trying to send as much as we possibly can to be recycled. We often have activities together with local school children to help bring awareness of the dangers of plastic pollution. We reduce our single plastic use as much as possible and all our vegetables and fruit peel leftovers are composted. We also protect the nests of turtles that hatch on our beach.

Are there any exciting changes / developments coming up in the near future?

We are partnering with Coral Eye Resort in Bangka Island so that guests can have the best service in the best areas of North Sulawesi. We are getting one more boat; we want to make sure our boats are never crowded, besides we keep working to maintain and improve all our facilities.

How do you see the SCUBA / Freediving / snorkeling industry overall? What changes would you make?

The industry is doing well and I am happy to see that there are more and more avid snorkellers and not only scuba divers. We would like to see more ocean protection worldwide to ensure the future generations get to enjoy the beautiful reef corals and marine life around the world.

Finally, what would you say to our visitors to promote the diving you have to offer?

We give you a chance to explore some of the best snorkelling and diving sites in the world while providing you with comfortable accommodation, wonderful food and the best service. Staying in Siladen Resort & Spa you can do up to four dives or snorkelling sessions every day with very experienced guides, while staying in a safe and comfortable resort that aims to provide the best service to each guest.
