OPERATION BISMARCK What To Expect On Your Dive The following information is provided to you as a basic guideline for your upcoming dive to the Bismarck. If you find you have additional questions not covered in this section, please contact us on info@deepoceanexpeditions.com 1. How do I get in and out of the MIR? Once inside the submersible, it is imperative that you get yourself as comfortable as possible and that you avoid touching or manipulating any of the control systems or instruments. Prior to your dive, you will be taken individually into the interior of the MIR and given a "tour" of its facilities to orient you for your upcoming experience. 2. What is it like inside the MIR? / What do I bring? As we dive, the temperature goes from somewhat hot and humid at the start, dropping to a constant temperature of 50°-57° F during much of the descent, during our time at Bismarck, and during the majority of the ascent. Please note, while this temperature does not seem to be too cold, the inside shell of the MIR is cold and moist due to condensation. Therefore, you want to make sure you dress warmly. It is recommended that you dress in comfortable, loose fitting clothes (tight jeans, for instance, are not recommended). You will need to wear your clothing in layers, allowing you to add or subtract layers to adjust to temperature variations. We suggest two pairs of warm socks; warm water-resistant booties; light thermal full-length underwear; a warm comfortable pair of sweat or fleece pants; a thick warm sweater, pullover, or fleece jacket; a woolen cap; and a light pair of gloves. In addition, we will provide everyone with a pair of special NOMEX overalls (suit) which is a fire-resistant garment. Your clothing will be inspected before the dive to make sure that you are adequately prepared. For the dive, we will provide you with a packed lunch and drink (not too much of either to avoid added bathroom needs). A hearty "welcome back" meal will await you at the end of the dive. In addition, we recommend that you bring a camera and/or compact video camera, tissue, a notebook and pen to record your observations, and a small tape recorder to record your impressions. Be aware that the following items are not allowed on the submersibles: anything made from a petroleum base (lip sticks, lip balm, Vaseline, some lubricants, etc.), matches, and lighters or other combustible materials. Please note that there is absolutely no smoking in the submersibles. 3. Exactly how does the "bathroom" procedure work in the MIR? As for "serious" matters, it is largely a case of "mind over matter" but a suitable device will be carried for absolute emergencies. In order to better control the need for the bathroom facilities, we will be recommending an eating plan that minimizes the amount of food and drink that you should consume for about 12 to 18 hours prior to your dive. You should also know your general needs and reactions and plan accordingly. 4. How does the dive operation begin? About an hour prior to dive time, you and your dive partner (either chosen by you or assigned to you) will be called to a final briefing and equipment inspec-tion. When the final order to prepare to dive is given, you will be escorted to the ladder for entry into the submersible on the deck of the Akademik Keldysh. Once you, your partner, and the pilot (who will speak English) are settled in and comfortable, the hatch will be sealed and the submersible lowered by the ship's crane into the ocean. The surface test team will inspect the outside of the MIR and then release it from the crane, after which a launch will tow the craft to its dive point (a little offset from Bismarck so that you don't land directly on top of it). This towing process can take a little time, and if the ocean surface is choppy, you will experience some rolling of the submersible. For some people this can induce some temporary motion sickness (it will quickly disappear once the dive starts and you descend below the surface). As a precaution, we advise those prone to motion sickness to use tablets (taken in advance) or behind-the-ear patches to help relieve symptoms. It is best to consult your physician for their recommendation prior to your trip. Once the pilot has checked all systems, he will slowly start to pump ballast water into the tanks, and the MIR will begin to descend. The descent rate will be approximately 100 feet per minute. The water color turns from light green, through the spectrums of blue, and in a short time to black as ambient light disappears at around 700 to 800 feet (200 to 230 meters), assuming, of course, that it is a daytime dive. It is worth noting, however, that we are not restricted to daytime dives, and there will certainly be nighttime dives made, especially if weather and sea conditions are favorable. As our dive does not rely on ambient sunlight underwater, day and night dives are of equal quality. The total descent time to Bismarck is about 2½ hours. During that time, you may relax, enjoy the music, watch the pilot manipulating the MIR, and/or scan the ocean depths for bioluminescent creatures. From time to time the pilot will turn on the submersible's powerful external lighting system to look for other marine creatures. All work inside the MIR is done by faint red lights (similar to a photographic studio) to preserve the pilot's night vision. The pilot is in constant voice communication with the Akademik Keldysh to assist his navigation. 5. Will both MIR submersibles dive together at the same time? 6. What is the size of the three MIR viewing windows? 7. What will the video memento be like? 8. What will I see of Bismarck? Time will pass quickly as the MIRs maneuver slowly and deliberately around the wreck; you will be entranced by its majesty and the sheer adventure and excitement of our endeavor. Ample time will be built in for photography and quiet observation. 9. How will we decide the dive order? bismarck.pdf (246Kb) |
