After the previous day’s success with the first core, the team was eager to collect as many cores as possible while the weather remained calm. With that in mind, the group was already underway on the coring rig shortly after sunrise. Click through the slideshow below to see what it’s like to work on the coring platform, which has no shelter or facilities.
Over the next few days, the coring team collected eight cores including one from each of the six sites. Several cores were 40 feet in length (previous cores from the Lake maxed out at ~28 feet), and one of the cores may have penetrated into glacial flour, meaning it may provide a complete record back to the last glaciation. Many of the cores contained significant amounts of gas, probably carbon dioxide, especially the Stevenson Island core. The team is thrilled with the coring effort and eager to see what stories the cores will reveal.
