Routine Cleaning

It is time once again for the CREWS buoy routine cleaning.  As you can see in the photos, we stir up quite a mess but it's all in the name of science!  Nothing out of the ordinary was observed and all reported data remains in the expected ranges.

Integration of Ocean and Light Data

It's not gone unnoticed that the light and ocean data from this buoy have until now not been included in AOML's reports and database.  This was due to a miscommunication between AOML, which processes the output of the buoy, and YSI, which created the buoy programming.  AOML's near-real time processing of CREWS data depends on having one hourly summary table with data from all station instruments, but the buoy's current program only provides 10-minute data summaries for light and ocean data and spreads these data summaries across three data tables, one per instrument.

I am in the process of altering the buoy's CRBasic programming to correct this problem.  Once these changes are complete the programs will be handed off to CCMI/LCRC for upload to the buoy.  Very likely this programming update will be timed to coincide with the buoy's annual refurbishment, when it will be brought to shore for cleaning, repainting, and instrumentation swapout.

We always knew that new routines would have to be created to process the first year's worth of buoy data after the fact.  Those routines have now been created, and with their creation it now becomes possible (through a minorly hackish kludge) to process ocean and light data in near-real time as well.

Complete data reports, including light and ocean data, are now available here for the first time:

http://www.coral.noaa.gov/static/data_ccmi2_Web_12.html

See also the links at the bottom of that page for "Detail" reports that include every parameter reported by the buoy, including diagnostics, and also the "Ten-Minute" reports that show some of the higher-frequency data that are summarized in the "Hourly" reports.

The light+ocean data have also been integrated into the "Ecoforecast" expert system that is running on our Gensym/G2 server:

And the light+ocean data are also queryable through our beta-versioned CHAMP Portal product:

http://www.coral.noaa.gov/champportal/

Note that the CHAMP Portal currently has known issues with user concurrency -- only one visitor at a time may run a query, while others who attempt to connect will see a progress message that will remain fixed in place until the first visitor's query has finished.  Developers are hard at work on this issue and we hope to release a fix very soon.

As a final note about CCMI2 data integration, I have now set up a feed of data from this station from AOML to the National Data Buoy Center (NDBC).  As of this writing the feed is undergoing quality assurance on the NDBC end.  I will post an update (including a link) once the feed has gone live on the NDBC web site.
