Special Great White Shark Expedition to Guadalupe Island.


Shark Diver is excited to announce that we will have a very special expedition to Guadalupe Island this fall. From Sept. 8-13 we will have both Nicole Nasby-Lucas, the scientist responsible for the Guadalupe Photo ID database and Tanya Houppermans, a world renowned underwater photographer on board.


Nicole Nasby-Lucas

Nicole has been studying the white sharks of Guadalupe Island, Mexico since 2001. Her research includes satellite tagging and tracking studies to examine migration patterns and behavior. She also manages the Guadalupe Island white shark photo-ID program and maintains a database of all sharks sighted at Guadalupe Island since 1999. The photo-ID program is important for tracking the visitation patterns of individual sharks as well as monitoring the overall status of the population. By using the unique coloration of these sharks, she’s been able to identify over 360 individuals to date. This project started in 2001 and some of these sharks have been seen every year since. All of this research is crucial for the management and conservation of northeastern Pacific white sharks.

All our guests will receive a copy of the official Guadalupe Shark Photo ID database. How awesome would it be if you can say "this is the shark that swam right next to me" the next time you watch Shark Week?

Tanya Houppermans is a world renowned underwater photographer and conservationist best known for her images depicting the grace and beauty of sharks.

 

Tanya Houppermans
 

A former mathematician and research operations analyst, she left the corporate world behind in 2015 to concentrate full time on conservation after learning that over 70 million sharks are killed every year with many species being on the verge of extinction. Her articles and images have been published around the world, and she is the recipient of several prestigious awards for her photography including her photo "Harmony" which won:

First Place awards in the ‘Sharks’ category in the World Shootout in 2017, First Place in the ‘Portrait’ category in the Underwater Photographer of the Year competition, and the Grand Prize in the California Academy of Sciences Big Picture Natural World Photography Competition. 

"Harmony"
 

A prominent public speaker, Tanya has shared her experiences in the underwater world with international audiences in locations such as Singapore, Shanghai, Paris, and Washington D.C. She is actively involved in cutting-edge shark research and helped to develop the citizen science program Spot A Shark USA to study sand tiger shark populations along the east coast of the Unites States. Tanya can be seen in the program ‘Shark Gangs’ that highlights her work with the sand tiger sharks of North Carolina as part of National Geographic’s SharkFest 2021.

On our expedition Tanya will share her vast knowledge of underwater photography, giving tips and advise to our guest as well as talk about her work in conservation.

Having both Nicole and Tanya on board will give our guests the unique opportunity to get to know our sharks, some of which we have known for over 20 years now, participate in the research and learn how to take awesome pictures and videos or our toothy "friends". 

We only have a limited number of spaces left on this special expedition. Call us at 619.887.4275 or email crew@sharkdiver.com for more info.

Let's go shark diving!

Science Expedition to Guadalupe Island

I booked the trip to Isla Guadalupe (Guadalupe Island) with Shark Diver of San Diego to fulfill a long held desire – since reading Jacques-Yves Cousteau’s “The Shark” and meeting his son in San Diego when I was a boy. And, in every way possible, this trip exceeded my expectations owing to the efforts of an outstanding Shark Diver team (particularly Martin Graf and Cindy Michaels), the Guest Marine Researcher Nicole Nasby Lucas, a fantastic Horizon crew, and great group of fellow shark divers. This is a must do in my opinion for anyone with a passion, interest or bucket list item relating to Great White Sharks – it’s fun, safe and amazing. Many details follow.

The Main Event:
I don’t want to bury the lead, so I’ll get right to our guests of honor. The Great White Sharks are impressive, majestic, and beautiful. They move by the twin cages, quite closely, at a stately pace, and look at the folks in the cage with large deep blue eyes; and, they appear utterly calm and in command. They make passes at the two bait carcasses off the stern, sometimes lazily and on occasion quite quickly. We were fortunate enough to witness a breach on one occasion – a male, who had previously made half-hearted passes at the bait, disappeared, the emerged from deep below the boat, under the cages, at speed, and hit the bait vertically from below, taking himself halfway out of the water – to the astonishment, screams and overwhelming joy of everyone aboard.


The visibility, typically, is very good at Isla Guadalupe, so the sun penetrates deep into the water and the boat casts a long shadow into the depths. Often our first sightings each time into the cage(s) were of the dark silhouette emerging from the shadow cast by the boat, coming up slowly from below and then circling the cages, bait and boat for some time before silently disappearing into the shadows again. Though each of us kept eyes peeled in all directions, it was amazing how frequently we were taken by surprise by a shark suddenly appearing. On deck, between dives, the crew is very experienced and keen eyed; and, they will call out “White Shark” as they approach, usually well before any guests see them. From above or below it is mesmerizing, and difficult to turn away.


Isla Guadalupe:
There are a few places worldwide to see Great White Sharks with predictability. Both South Africa and the Farallon Islands offer this opportunity; but, both have limited underwater visibility and challenging water temperatures. Isla Guadalupe has better water clarity, 100 foot visibility, and weather, and very few (we saw only three other) boats, some distance away. Unlike other locations, Isla Guadalupe will not force you to deal with cold and murky water, crowded boats and cages, quick “in and out” quick thrill experiences, etc. You will have days on the dive site, in relatively warm and very clear water, and good weather.

#153 he needs a name! You can name him by clicking here
Isla Guadalupe is a designated Bio Sphere, a marine sanctuary. It sits about 200 miles southwest of San Diego. It is made up of volcanic remnants and has a stark beauty, with tall, steep cliffs diving hundreds of feet down to sea. There are large populations of, and rookeries for, elephant seals, sea lions – all of which you are very likely to see, with approaches to boat on occasion.

Timing:
Typically, though as Martin notes there are no hard and fast rules with White Sharks, they tell us the males will show up in earlier months – e.g., July, August, and September – and in greater numbers. And the typically October and November are when they have female sightings – the females being fewer but much larger than the males. Also, typically, the wetter weather comes later in the year, with the Pacific hurricane / wet season; but, this too is not always the case.

The Drive Out:
It is a long trip out to, and back from Isla Guadalupe from / to San Diego. It was some eight hours from San Diego to Ensenada Mexico, where we docked to have passports checked, and then a long 18 +/- hours to Isla Guadalupe. Note that the return trip is the same itinerary, in reverse, with a stop in Ensenada before entering U.S. waters. Along the way out to Guadalupe, a large pod of dolphins escorted us. The sea can often be a bit rough to quite rough, with good swells causing a fair bit of roll onboard. Owing to timing, much of the initial leg is spent hanging out in main cabin getting to know fellow divers, with folks eventually heading to their beds – sleep and good anti motion sickness remedies work well. Most folks used some combination of ear patch and oral medication. It’s a long drive, so be smart and just bring your meds.



The Boat:
You won’t “Need bigger boat”  The MV Horizon the Horizon is roughly 80 feet long with 8 state rooms and several bunks. There are two restrooms and showers that are shared by all. The accommodations (two persons to a room with curtain for privacy and in bunks) are not lux, but they are nice, and you won’t care anyway  The Horizon is used only as diving vessel; and that's all season long. They determine who bunks together once everyone arrives in San Diego, based on number of couples, individual travelers, etc. The sleeping quarters are below,, and the main cabin contains the galley and a series of booths along each side used for dining and spending time together with travelers in route or between dives. Net / net, this is a large and comfortable boat.


The Cages:
There are two, kept on deck astern for the trip and each night when diving is completed. For each day's diving, each is suspended off, but affixed to, the stern at the surface (that is, they do not sink below) – so you simply climb down a ladder and into the cage (easy); and each easily holds four divers. One cage is aft port, one aft starboard. You will alternate each dive, so that everyone has plenty of time in each cage.


 The Dives:
The divers are assigned to two teams. Each team dives for an hour, and then rests and re-hydrates for an hour while the alternate team dives. Each team has four people in each cage, and the team alternates cages each time, so everyone gets to try both cages and gets plenty of dive time and rest. There were a couple days of early open diving as well – starting just after sunrise – during which anyone who preferred could climb into either cage.


The crew will size you for suits, equipment, weights, and Martin himself oriented each of us to breathing via air hose and made sure we comfortable before we stepped fully down into the cage.
Safety is primary and at no point was anything but utterly assured all was well and well in control. No divers are ever permitted out of the cages – for the sake of the sharks, the marine preserve, as well as the divers. You are completely safe at all times. There were folks of all ages, bith genders, and widely varying experience levels. Past trips have included folks in their 60’s and 70’s, and quite young divers as well. The always amazing Cindy at Shark Diver can advise on particulars.

Breathing with the hookah system is easy – no metal tanks to strap on, simply a long hose that goes from on deck tank system to each diver’s regulator (mouthpiece through which you breathe). So, if you’ve ever snorkeled and used a mask, you’ll be just fine. The cages are beyond sturdy, offer complete visibility around, above and below, and are plenty large enough for each set of divers.



The Purpose:
In addition to the opportunity provided to guests to see these amazing creatures, each shark observed is photographed (Martin, Nicole and the divers get to participate in this) and compared to a database of previously observed sharks. New sharks are named and tracked in the database each successive year. This is a joint effort between the Marine Conservation Science Institute (MCSI) and Shark Diver.

Newly identified sharks on a particular dive are named by the people on the dive in a bidding process (proceeds of which go to the MCSI and shark research effort). On a side note, I was fortunate enough from a 2014 dive with Shark Diver to name one – Hooper (after the Richard Dreyfuss oceanographer character in Jaws) – great fun and a great way to support the cause.

# 159 Hooper
Isla Guadalupe is home to a marine preserve and a research station manned by a researcher named Mauricio – who will visit the Horizon and give an excellent presentation with Martin on Great White Sharks and the Isla Guadalupe Bio Sphere.

The Shark Diver Team:
Martin Graf, the CEO and dive leader, teacher, host is a deeply experienced and great guy. He is hands on, overseeing everything on the dives. He also gives talks and a presentation to the divers on Isla Guadalupe, Great White Sharks, and many experiences with both. If Nicole Nasby Lucas (again, researcher from MCSI) is leading Science Expedition, she, too, will give a fine presentation, talk. Both Martin and Nicole worked each evening on identified sharks seen from photographs taken during the day. All the reservations, logistics, arrangements, and care taking of the divers before and after is led by the excellent and omnipresent Cindy Michaels, their Director of Communications – Cindy was a rock star and took care of every question and need leading up to the trip.

The Horizon Crew:
In a word, excellent. Experienced captain, crew – professional, easy going, genuinely friendly, and they take care of anything you might need. I cannot say enough good things about the crew of the Horizon.

The Food:
As noted elsewhere, the food is outstanding. The quality and quantity of the meals is positively surprising and uniformly excellent. There is also beer and wine aboard. There are large and delicious breakfasts every morning cooked to order, excellent lunches (including Sashimi), and absolutely fantastic dinners, including prime rib near end of stay. The galley will account for you preferences and restrictions with no problem.

Thank you David Moore! We appreciate you taking the time to share your experience with us and our future divers. We are glad you enjoyed your expedition and hope to see you again on another shark trip.

Cheers,
Martin Graf

Do you want to join a researcher at Guadalupe Island?

Every year we get hundreds of emails from people asking us, how they can get involved with shark research. This has lead to Shark Diver teaming up with Nicole Nasby-Lucas from MCSI to offer special science expeditions to Guadalupe Island. These special science expedition give our divers a chance to actively participate in the Great White Shark photo ID project and also learn about the results of various studies, involving our sharks at Isla Guadalupe.

The response from our divers has been overwhelming. Last year's science expeditions filled up in just a couple of weeks and for this season, we already sold out our September and October expeditions. Right now, we do have a a few spaces left on our November 11-16 expedition.

Don't miss your chance to be part of this exciting research, which up to today has resulted in over 160 sharks being identified at Guadalupe Island. Some individuals like "Bite Face", "Jaques", "Thor" and "Chugey" are regular visitors and have been seen every year since we started going to Guadalupe Island. You will learn the differences in behavior and migration between male, female, juvenile and adult sharks along with many other interesting things about Great White Sharks and sharks in general.

Nicole has a wealth of information and is excited about sharing her knowledge with you, our divers and research assistants. She will teach you how to identify the individual sharks and tell you about their history at Guadalupe Island. Just imagine, next time you watch "shark week", you might recognize the shark and realize that it's the one you came face to face with. The one that looked you straight into the eyes!

If you would like to be part of this experience, we recommend that you book now, since this is your last chance to join a scientific expedition in 2015.

The price for this trip of a lifetime is $3300 and it includes a copy of the photo ID book, containing all the identified sharks at Isla Guadalupe. We will also provide digital underwater cameras for you to use and you'll get a DVD of your trip to take home and share with your friends. If we encounter a new shark during your expedition, the group will be offered and opportunity to name the shark!

This special science expedition will run from September 11-16 2015

To book your expedition, or for more information, call us toll free at 855.987.4275 or 619.887.4275. You can also reach us via email at staff@sharkdiver.com or visit http://www.sharkdiver.com/dive-packages/great-white-shark-diving-science-expedition/

Let's go shark diving!

Do you want to see the big "girls" at Guadalupe in November?

Our 2 science trips for this September have sold out in just a couple of weeks and we have been getting a lot of interest in doing another trip in mid November, when the truly enormous females dominate the waters off Guadalupe Island. 

That interest and the fact that our Great White Shark database is in need of pictures of the big, late season females, we have decided to add a special science expedition from November 11- 16.

We are proud to announce, that  Nicole Nasby-Lucas from the Marine Conservation Science Institute, the scientist that started the Great White Shark photo Id database at Isla Guadalupe, will again be joining us on this special expedition to photograph and identify the large females. She will also be sharing her research with our divers and showing everyone how to identify the sharks. So far the database has over 150 individual sharks identified and some of those individuals have visited Guadalupe Island every year since first being identified in 2001. It is amazing to see how those sharks change in size and behavior.


This expedition is a unique opportunity to participate in growing our database. Should we find a new shark, which is fairly likely during that time of the year, the group will get the opportunity to name the shark. Imagine seeing a shark on a future television documentary, knowing you were there when we first encountered it. All the participants will also get a copy of the photo ID book, containing all the identified sharks at Isla Guadalupe.

The price for this special expedition is $3300 and is limited to 18 divers. We recommend that you book early, since our last two science expeditions sold out in just a couple of weeks.


To book or for more information, call us toll free at 855.987.4275 or 619.887.4275. You can also reach us via email at staff@sharkdiver.com

I hope you can be part of this exciting expedition!
