Saturday's dive
Sorry for the crappy photo.
The wreck diving at Bjuröklubb was scheduled for 27-29/7 but since I was working on Friday I arrived to late for Friday's dive. The following day I got up at around half past nine. One of the compressors had been running a few minutes and even though I could rest fairly comfortably I couldn't sleep, might as well get up.
I had a light breakfast and spoke to some of the other divers. Today we were going to dive the Syria. Syria was sunk at N 64.22.0 - O 21.36.0 on July the 16:th 1916 by the Russian sub Vephr. Vephr fired three torpedoes which hit Syria astern, mid ship and at the bow. Syria was transporting iron ore from Luleå to Germany and due to it's heavy cargo it sank rapidly but the entire crew of 23 men, one pilot and one pilot apprentice was rescued. The wreck lies at 22 meters depth just outside Bjuröklubb.
We had two boats at our disposal, "Bulan" and "Explorer", each towing a dingy. We stowed our gear onto the boats and got into our dry suits. The boat ride took roughly 70 minutes one way. There was a constant light rain in the air and the winds were picking up. After about 40 minutes at sea a lot of people did not look all that well. As we got to the position we called up "Explorer" and asked her to drop anchor at the wreck. We paired up and the dive leader documented the dive teams. I dove with my instructor as this was a course dive for CMAS 2*. Dive time was decided to be no more then 40 minutes. We got into our vests and prepared to dive. Out of paranoia and caution I did not fasten the vest clip that is positioned closely to the button that inflates the suit. During a dive in the river that very clip pushed down on the inflator which slowly and quietly filled the suit with air, pulling me to the surface despite my attempts to empty the air through the escape valve.
We made entry onto the water from the dive platform and swam towards the descent line. My instructor went down first and I followed behind. I could see roughly 7 meters down the line, beyond that there were just darkness. At around 19 meters there was a large sheet of metal against which the line was resting. As we hovered past it I could see the bow of the ship. Beyond the bridge the decks lay like an open landscape below. It was quite a sight. Much of the wooden deck was still in place although parts were torn open to reveal the rooms below. There were several holes on the deck including what looked like a brick chimney. My instructor picked up what looked like an S-shaped pipe while hovering just above the deck. He handed the pipe over to me and I immediately sank to the deck a few inched below. The pipe was massive, not very long but very thick and quite heavy. Daylight was sufficient to illuminate the decks well enough for navigation but inside the ship it was pitch black. I turned on my Underwater Kinetics Q60 and looked into the holes. There were usually not very much to see inside since most of it was torn by the explosion and ravaged by time - but it was still hard to just swim by without examining more closely. The white light of the Q60 pierced the darkness with a sharp concentrated beam. We swam past the deck and over a cargo hold. It extended down perhaps 5 meters into the dark belly of the ship. My instructor went down into the hold. Although the opening was fairly large I waited for him to get down before I made my way down. When you're lying horizontally and wearing fins you take up a lot of space. I raised my left arm to let air out of the suit and ascended into the hold. Around the edges of the opening there were steel support columns. We looked around for a while and then my instructor went back up onto the deck. I waited for my instructor to clear the hold and then made my way up. At this point I was rather careful not to over inflate the suit, if I filled to much air into it I would probably not be able to stop my ascent. Just at the top of the hold I kicked something with one of my fins. The first thought was that I just kicked the regulator out of my instructors mouth. I stopped moving my legs and turned 180 degrees to my left but I didn't see anyone. At this time a second dive pair swam by the hold. I turned my light into the hold but couldn't see anyone or any bubble trail. Well, the good news is that I probably didn't kick anyone. The bad news is that our two man team just became two one man teams. I decided to stay at the hold, if my instructor was going too look for me this was probably the first place to search. I looked 90 degrees to my left and saw my instructor at a distance, looking around for someone - presumable me. I flashed my light in his general direction and swam up to him. We started to move back over the deck towards the bow. At the end of the deck there were debris from the bridge above. I could clearly make out several faucets and a tile floor in the beam of my flashlight. As I looked above I could see the torn upper deck stretching above my head. We swam back and over the bridge to the line. We made our way up the line to 5 meters were we made a decompression stop for three minutes. My instructor hooked his Jon line to the ascent line, I held my right arm above the line just in case. The idea is to "hang" at the line, using it as a reference point without actually holding on to it. Suddenly the line dropped a few meters. Apparently one of the divers above had a too negative buoyancy and pulled the line down with him. As I looked up I could see a diver trying to swim to the surface only to be grabbed by his dive buddy which signed to him, in no uncertain terms, that he MUST stay for the entire decompression stop. After a while the line stabilized again and the top most pair broke the surface. Shortly there after we ascended to the boat and swam to the diving platform. We handed over out weight belts and climbed the dive ladder. Syria may be ravaged by time and Russian torpedoes alike but it still offers great diving. We stowed away our vests and waited for the other divers. As all divers were accounted for there were only a hand full of people in shape for a second dive. My instructor had a slight shift in the skin color of his face and didn't really feel like diving again - even though he was the number one candidate for retrieving the anchor at the end of today's dive. Only four divers went down for the second time, one of which nearly got puked upon on his return. During their dive time the winds started to pick up and the dive platform was savagely striking the surface of the water for each big wave. As the diver ascended it was decided that divers should only enter the platform from the side to prevent getting struck on the head by either platform or ladder. There were two of us on the platform, one on either side. The divers handed their weight belts and fins to us and we helped pull them on board. Shortly there after we pulled up the anchor and made our way back to Bjuröklubb. After our deco stop we swam up to the boat. I was as good as out of air but my instructor made a short dive to try to locate the wreck that should be around here somewhere. I climbed aboard and stowed my equipment. The other divers joined shortly. That was the end of that day's diving. We returned to the harbour and unloaded our gear. Today's dinner was surströmming, very tasty but an acquired taste to say the least. Later in the evening we broke out the whisky, brandy and cigars - well, no cigars for me thought but plenty of whisky (both Laphroaig 10 years and Ardbeg 18 years) and a hint of brandy. As for cigars, I've sold off my humidor and quit smoking as advised by the doctor I saw about my lunges, which was probably a good idea but the other doctor is not going to like that I sold off his access to a cigar habitat (sorry dad).

At the harbor we had some refreshments and shortly there after my instructor, me and another dive pair was on the next boat out to a small wreck just off the harbor. My 10L 300bar bottle (3000 liters of air at 1bar/surface) was not filled yet, so I used my 12L 200bar bottle (2400 liters of air at 1bar/surface) instead. The other dive pair was going to see the wreck, we were going to practice breathing two divers on one regulator, buddy breathing and mask emptying at 21 meters. The boat took us out to the presumed position of the wreck and we went down the descent line. At the bottom my instructor attached a search line and we swam roughly 15 meters out were we made a stop. My instructor signaled "empty mask". I let some air into the mask from my nose in order to remove the mask without getting squeeze on my eyes. As the mask was slightly over pressurized I held it and slid it right of. The pressure forced some water up my nose but there weren't much to do about that, I just concentrated on the breathing and putting the mask back on my head. I held the strap with both hands and hooked it over the back of my head and pulled the mask over my eyes. I emptied the mask, tucked the seal of the mask underneath the hood and signaled "OK". Then we made a circle search around the ascent line for a while. My instructor then signaled "no air". I took a deep breath and handed him my main regulator. I exhaled constantly but slowly to prevent lunge damage if we were to rise against the surface. I held the regulator at the hose and my instructor grabbed my hand, that way the assisted diver can still reach the purge button. We each took two breaths then handed over the regulator. After a while my instructor signaled me to hand over my secondary regulator and use the main myself. I gave him my secondary air source and we swam along the line for a while. I held on to his vest's shoulder strap in order to make sure that we did not get separated. The hose for the octopus is longer then the main, but we still had some problems since the hose extended from the first stage's right side and the regulator was connected to the hose on the right side. In other words the hose most be positioned from my right side, behind the other diver's head and to his mouth. After a short swim I looked at my manometer, 50 bar - just into the red area. The general rule is use 1/3 of the air diving, 1/3 to get back and 1/3 as backup. I only had a 1/4 of my original air supply left and we were two divers breathing from that tank. I showed the manometer to my instructor and he switched back to his main. We swam to the line and ascended to 5 meters were we hovered for 3 minutes of decompression. It's a strange feeling to float almost weightless in the water. For every inhalation I moved closer to the surface and for every exhalation I moved closer to the bottom. Every time I moved closer to the surface the pressure against the suit decreased and my lift increased, every time I moved closer to the bottom the pressure squeezed the suit and lift decreased.
