An example ingrowth curve and the seismic record that led to the Gorda event response are also shown, tied to calendar time and sample ages. This figure is from an article in the NSF Ridge2000 program newsletter (Spring 2005, which is available in pdf-format) For more info please see these papers, and the references therein: KH Rubin, SA Soule, WW Chadwick, DJ Fornari, DS Clague, RW. As a result of the diverse and extensive experience, our staff can anticipate and resolve many problems that might occur before the analysis of an individual core is begun. We have also applied this technique to lavas collected after suspected submarine eruptions at NW Rota-1 seamount, the Northeast Lau Spreading Center, Axial Seamount (project underway), the 2005-06 eruption at 9° 50'N and 2004 eruption 10° 45'N on the EPR, the Gorda Ridge, Boomerang Caldera (near South East Indian Ridge), and the Loihi Eruption in Aug 1996.As of June 30, 2019, My Core Scientific has “retired”.Our new company will be taking over the business and will be providing to My Core’s customer base and new clients the same quality 210Pb dating services that a small personal company can be picking up from where My Core has ended.The 2-month window we currently report is based on observations at 9°50'N EPR (panel A), although the still preliminary data from 1044'N EPR (panel c) may allow us to narrow eruption window widths because 3 of 4 samples were 75% degassed of Po upon sample collection.Errors in maximum age (gray horizontal bars) reflect data regression and analytical errors (see the eruption window inset).
Absolute and relative times are given at the base of the plot.In addition to taking an active part in a number of research projects, the laboratory carries out age measurements under contract to Historic Environment Scotland.We also provide a radiocarbon dating service to national museums, academic staff in a large number of universities worldwide, and many UK and European commercial archaeology units. We developed this dating method back in 1991 after divers in the manned submersible Alvin appeared on the scene soon after a submarine eruption at 9° 50'N on the East Pacific Rise (EPR), to determine when the eruption had occured.Pb dating results from 3 eruptions on the EPR and Gorda Ridges.
