A setback

We’ve discovered that we won’t be able to install the knife gate mechanism for the ADCP (funded by our MRI grant) because the design of the new research vessel doesn’t have enough space for it. Without the knife gate, deploying and servicing the ADCP will be somewhat more difficult. We have asked NSF for permission to use these funds towards purchase of a Conductivity Temperature Depth (CTD) profiler/rosette system instead.

This piece of oceanographic equipment, like the other equipment purchased with the MRI funds, will further the use of technology for teaching undergraduates. If we are allowed to use the funds this way, we’ll need to make up the difference in cost. Middlebury College and a local foundation will help.
