| Résumé | (disponible en anglais seulement)
The PharmaDeep Expedition was a EUROFLEETS2 funded project that combined traditional marine biological and geological exploration with the search for new
bacterial 'extremophile' communities in the quest for the next generation of pharmaceuticals.
The South Shetland Trench, located near the Antarctic Peninsula, is one of the few cryogenic, deep-sea trenches in the world. The Expedition aimed to
collect marine organisms from deep-and-cold-water habitats which may prove valuable pharmaceutical potential; to perform the first known biological and geological survey of the South Shetland Trench; and to compare the fauna and drivers controlling
their distribution to other trench ecosystems.
Between the 13th and 29th December 2015, 14 researchers from a range of disciplines sailed on the Spanish research vessel BIO Hesperides. The operational scientific days allocated to the project
totaled 6 days during which time 4 baited lander deployments, 8 gravity core sites, 2 multi-cores, 3 beam trawls, 10 zooplankton hauls and 19 phytoplankton hauls were conducted. Additionally, 3148 km2 of multibeam echosounder data and around 600 line
kilometres of Topas sub-bottom data were acquired covering part the southern flank and trench floor of the study area.
Although the expedition objectives were met, this was not without its challenges, including permitting, a shortage of bunks,
weather, sampling troubles, an inordinate number of icebergs and Christmas.
We will present some of the technical and logistical challenges encountered working in this remote environment and summarize some of the key findings from the
expedition. |
