Abstract:

Workflow in most ICDP deep drilling project seems to be much less standardised than is the case for IODP projects. We therefore take this as an opportunity to present field and lab protocols that were applied during the drilling and subsampling campaigns of the ICDP project PASADO (Potrok Aike Maar Lake Sediment Archive Drilling Project). According to our knowledge, PASADO was the first ICDP project where continuous subsamples were taken for the entire sediment sequence (106 m). Lake drilling in Laguna Potrok Aike was carried out in Sep. to late Nov. 2008. In total 510 m of lacustrine sediments have been recovered using the GLAD800 platform equipped with a CS-1500 drill rig . At two drillsites quadruplicate (site 1) and triplicate (site 2) cores down to a maximum depth of 101.5 m below lake floor have been taken with a high recovery rate using mainly the hydraulic piston coring (HPC) tool.
