For Scientists and ETs on the Laurence M. Gould:


The OS38 data acquisition system displays green panels when the raw data streams have a good checksum. Fundamentally, if the panels on the display have numbers in them (then they acquired data) and if they are green then the data are good. More information about UHDAS is contained here.

If for some reason the figures quit updating, check the panels and make sure everything is green. If they are, DON'T ADJUST ANYTHING: the raw data are good, but the processing software hit a glitch for some reason. There is a good chance things will recover at the next even 2-hour interval, when a new data file is started. If it does not, the ET may start data acquisition again under a new cruise name in an attempt to re-initialize the processing, but it this still does not revive the figures after several hours, email us and we will try to help (hummon@hawaii.edu, efiring@hawaii.edu).

When we get the data after the cruise, we will process it and send it to the chief scientist if they are interested. Scientists are free to walk off the ship with copies of figures from the web site and the matlab files distributed there, but please remember, the data contained there are preliminary. If you intend on any serious use of these data, please contact us to see whether there are updates or notices regarding the status of the processing or your particular dataset.

Thank you
