  1. Summary Carol Johnson NIST

  2. Technological Improvements • New Buoy Design • Solar panels, power on mooring buoy • Reduces weight/size of optical buoy • Smaller, lighter optical buoy can be deployed from a much smaller vessel • Go from $22K/day to $2K/day ship costs • Applicable for coastal environments • Updated communications systems • More capabilities to monitor/download data/change configurations/trouble shoot remotely

  3. Technological Improvements • Evaluating new spectrograph design • Based on Volume Holographic Gratings • Simple design, f/1.8 • Better imaging, thus more inputs • Multi-track fiber input • Enables simultaneous observations, reduce environmental noise • Reduce/eliminate self-shading effects (multi-arms) • Apogee Camera Systems • Ethernet-compatible (stable communication) • Extensive experience in oceanographic instruments • Simple power supply, no external cards/control cards

  4. Technological Improvements • New calibration sources • More flux in the UV (better s/n & stability) • Better spectral match to measurement • Reduce sources of systematic error • New Hyperspectral Source Monitors for laboratory calibration • Complete spectral monitoring of source distribution, improved endpoint calibrations

  5. Technological Improvements • UV-LED-Based anti-bio-fouling • 265 nm LEDs, optimized for breaking DNA bonds • Better anti-fouling means longer deployments/fewer diver cleanings, reduced operational costs • Internal & external in-situ calibration sources • Better monitoring of responsivity in situ • Better tracking of responsivity changes • Lower overall uncertainty • Contributes to longer deployments

  6. Current status of R&O BuoyPrimary Equipment • Tether evaluated • Discussed earlier, first attempt failed-future plan to address this • Spectrographs and cameras on-order • Delivery date August - September

  7. R&O BuoyAncillary Components • Anti-fouling LEDs in house • Field-test planned in Mill Creek, Fall 2006 • New calibration source development • LED source prototype tested • Revised source under development • Rev.2 should be ready this fall for evaluation testing • Detector-based source standard under development • Prototype ready for preliminary testing this fall

  8. AHAB Milestones • MIFS breadboard evaluation by 4/07 • MIFS prototype final by 12/07 • MIFS production delivery 5/08 • AHAB mooring delivery 6/08 • AHAB test deployments start 8/08 • AHAB/MOBY crossover 3/09 to 2/10 • MOBY decommissioned 3/10 • AHAB operational starting 3/10

  9. Schedule • GOES-R • 2012 launch (GOES-E or GOES-W?) • GOES-E Site established 2010 • Manned with buoy 2011 (1 year in place prior to launch) • GOES-W Site Established 2015 • Manned with buoy 2014

  10. Funding • ROSES2006: Proposal submitted for building new AHAB system and covering operational shortfall • NOAA: committed to significant help towards MOBY operations • Future: starting in FY09 NIST/NOAA initiative so NOAA should be picking up AHAB operations.
