Geocache Description:


HR: Cache nije na danim koordinatama, ali tamo su se ove hrvatske podmornice koje su dio naše priče projektirale, razvijale…

Dogodilo se i to da su naše podmornice konačno napustile vojnu bazu i sada služe isključivo za istraživanje i proučavanje podmorja. U ovoj priči to je podmornica patuljak, klase Velebit P01 sa četiri člana posade koja je prevozila četiri mokre ronilice R01 kojima upravlja po jedan ronilac znanstvenik koji se nalazio u podmornici te još jedna ronilica R02 koja prevozi dva ronioca koja mogu napustiti usidrenu ronilicu i istraživati okolno podmorje.

Na taj sunčani ljetni dan kada je na temperatura dosezala i 45°C, temperatura mora i nije bila baš ugodna za kupanje, iznosila je  15°C. Tlak na površini mora je iznosio 1 atm, a svaki odgovorni podmorničar zna da je to 101325 Pa. Posada podmornice P01 je upravo završila s mjerenjem saliniteta i gustoće mora na tom području. Rezultati su vrlo precizni.  Gustoća mora je bila 1032,8745 kg/m3.
Sretni nakon napornog istraživanja odlučili su se odmoriti prije povratka u znanstvenu bazu. Nije čudilo, kad su posadu činili svi redom geocacheri i da su za taj popodnevni odmor organizirali i Event Cachei to na EarthCache-u otočića. Kako zgodno. Tamo ih je dočekalo još 13 geocachera koji su također prvi put na ovom otoku!

U ronilici R02 oba geocachera su htjela prije susreta sa P01 pronaći što više podmorskih cacheva, što je značilo zaroniti sa ronilicom što je dublje moguće. Međutim, imali su ograničenje. Sila koja im je bila na raspolaganju za otvaranje poklopca dimenzija 65 x 60 cm je bila 94840,2 N. U ronilici je vladao tlak od 1,6 atm, a na površini mora je tlak 1 atm. Nisu gubili ni trenutka i već su bili usidreni.

Dok su naši prijatelji iz ronilice R02 pretraživali podmorje podmornica P01 je zapažena pokraj plutače B1 u 10:25 AM, kako bi stigla na Event do plutače B7 pet minuta prije podneva, bilo joj je dovoljno da na površini plovi brzinom od 0,4 čvora. Za to vrijeme su se četiri geocachera spremala u lov na kutijice na svojim mokrim ronilicama R01.

Cache se nalazi na koordinatama:

Sjever: A B.C

Istok: D F.G

  • A: temperatura zraka na Event-u
  •  B: broj logiranih posjetitelja ovog EarthCache-a taj dan, plus broj sudionika Event Cache-a (uzimajući u obzir da nitko nije propustio logirati svoje ostvarenje)
  • C:  dubina na koju je zaronila ronilica R02 u decimetrima
  • D: temperatura mora
  • F: ukupni broj logiranih cacheva ovog šarenog geocacherskog  društva. Geocacheri na mokirm roniliciama su imali ograničenje zarona od 20 m. dok ronioci iz ronilice R02 nisu izlazili na površinu tražiti cache-ve. Cacher koji je pronašao cache s površine, nije išao tražiti podvodne cacheve.
  • G: Prevaljen put ronilice R02 s mjesta na morskom dnu na koji je bila zaronila do Event-a u metrima. Uzimajući u obzir da je prvi manevar bilo izranjanje okomito prema površini, a zatim plovidba naprijed do plutače B7 čemu valja nadodati 227,4 m koje je ronilica napravila tražeći pogodan vez na Otoku.

Ako je potreba, gravitacijska konstanta je g= 9,81m/s2

 

ENG: Given coordinates will not bring you to the cache itself but rather to the location where these Croatian subs were designed and developed...

It finally happened! Our submarines left the naval base. But they are far from being retired. Although they ended their honorable naval duty they are now used exclusively for scientific research and underwater study. In this story our main actors are: one submarine dwarf class Velebit P01 with crew of four submariners, which carries four wet submersibles R01 each managed by one diver scientist. There is one additional and independent wet submersible R02 transporting two divers who can leave once anchored submersible and explore the surrounding seabed.

On this sunny summer day the air temperature reached 45 ° C and the temperature of sea water was not very pleasant for swimming - only 15 ° C. Pressure on the sea surface measured 1 atm, and every responsible submariner knows that this is 101325 Pa. The crew of submarine P01 had just finished measuring the salinity and density of the sea water in the mapped area. The results were very accurate. Seawater density for example, was 1032.8745 kg/m3.
 

Happy after a long research, they decided to take a break before returning to the scientific base. It was not surprising, when the crew, who all of them were Geocachers, for the afternoon relaxation organized Event Cache at the EarthCache Isle. How convenient. There they met another 13 Geocachers who are also first time on this Island!

In the submersible R02 both Geocachers wanted before meeting with P01 to find as many underwater caches as they can, which meant to dive with the sub as deep as it can. In this case they had the restriction. The available force for them to open the hatch dimensions 65 x 60 cm was 94,840.2 N. The acting air pressure inside the submersible was 1.6 atm and at sea level is 1 atm. They wasted no time and were already anchored at the seabed.

While our friends from the R02 searched the underwater, submarine P01 was spotted near the buoy B1 at 10:25 AM, in order to arrive at the event at the buoy B7 five minutes before noon, it was enough to cruise the surface at speed of 0.4 knots. During that time, four Geocachers were ready to hunt for boxes riding on their wet R01s.

The cache is located at coordinates:
North: A B.C
East: D F.G

- A: air temperature at the Event in °C
- B: the number of logged visitors of EarthCache plus the participants on the Event Cache (taking into account that no one failed login its presence)
- C: the depth at which the submersible R02 dived in decimeters
- D: the sea temperature in °C
- F: the number of all logged caches of this colorful geocache society. Knowing that: geocachers from P01 had a dive limit of 20 m. While divers from submersible R02 did not went on the surface to look for the caches. Diver who found the Cache on the surface did not go to look for underwater Caches.
- G: the distance in meters that submersible R02 traveled from place on the seabed to the EventCache in meters. Taking into account that the first maneuver was perpendicular to the surface, and then the submersible sailed forward to the buoy B7. To that one should add 227.4 m, which RO2 made trying to find the suitable place to anchor on the island.
If necessary use the gravitational constant g = 9.81m/s2
