Warto obejrzec - patrzac na tak zrealizowane projety GUE, rosnie coraz bardziej nasze zrozumienie tego, ze nurkowanie to nie tylko niezla zabawa, ale i umiejetnosc przedstawienia i podzielenia sie ta "zabawa" z innymi. A sa to tylko nurkowie, nurkujacy i przedstawiajacy swoje nurkowania - ale czy aby na pewno "tylko"?
Tak powinnismy kontynuowac nasz rozwoj - coraz bardziej dostrzegam, ze nurkowe GUE moga faktycznie zostac kolejnym pokoleniam nastepcow Cousteau - nasza misja faktycznie nabiera konkretnych kszaltow - przez edukacje, do eksploracji i do ochrony srodowiska, a raczej uswiadamiania jego znaczenia historycznego, ekologiczengo i ekonomicznego. Dzialamy !!! |

Fragments of monk seal bones (Monachus monachus) discovered 7–12 m
below water level in Bel Torrente Cave (central-east Sardinia) in 2004 have been AMS radiocarbon dated. The bones, probably of different individuals, have calibrated ages ranging from 5000–6500 calendar years B.P. and allow reconstruction of the paleogeography of the cave and the surrounding area during this time period. Monk seals living in large numbers along the Sardinian coast used the cave for shelter and to give birth to their pups. The lower sea level of the mid-Holocene, combined with cave morphology, allowed them to reach far into the main tunnel of the cave. The large number of bones found of approximately the same age seems to indicate that the monk seals used caves either to shelter from storm waves or to escape from natural predators during periods when human disturbance of the coast was minor. This could suggest the monk seals had other predators they were also trying to avoid. |
