WWe
have two buoys in the water near VIMS:
Gloucester Point Real-Time Data Buoy and Meteorological
Node
The VIMS Gloucester Point data buoy is the first step
in a long-term project to provide real-time data for accurate predictions of
ecosystem processes in Lower Chesapeake Bay
A weather station is mounted on a pier at
VIMS near the buoy and the buoy itself houses an additional anemometer, a YSI
6600 Environmental Monitoring system measuring water temperature,
salinity, dissolved oxygen, turbidity, and fluorescence. Two RD Instruments ADCP's (Acoustic Doppler Current
Profilers) mounted in bedframes provide information about the real time waves
and water velocities at GloucesterPoint.
The location of the VIMS Buoy is displayed on the map here. Real-time data are here.
Goodwin Island Real-Time Data Buoy
The Goodwin Island Nomad buoy is located on the north side of Goodwin Island
near the mouth of the York River. It represents a collaboration between SAIC,
VIMS, and other organizations. A
Nortek AWAC (Advanced Waves and Currents)
Doppler profiler is moored nearby and communicates with the Nomad via an
underwater acoustic modem. Both buoys
communicate with VIMS through HF radio modems. A weather station is mounted on the buoy and
real-time data will be available shortly.
The location of the Goodwin Island
Buoy is displayed on the map here. Real-time
data are here.
These buoys are the first in a planned network to
extend the Chesapeake Bay Observing System (CBOS) into the lower Bay.
This comprehensive network will provide simultaneous measurements of winds,
waves, currents, water density, nutrients, water quality, biological indices
and fish stocks under all conditions. Basic
and analyzed data and linked numerical models will be accessible in real-time
and at high-speed through a web portal. Funding has been provided by the Commonwealth of Virginia
and the U.S.
Coast Guard. Predictions made by this
system can help guide the management of natural resources, enable planning
for extreme events, facilitate maritime operations, support military
security, and advance science and education.

WARNING!!!
These Data Are Preliminary!
No QC has been done to them!
These data are in NetCDF format and most have also been
converted to text files.
Unless otherwise specified, files are for an entire month
and data time intervals are as specified by the instruments.
The NetCDF files contain a small amount of metadata
detailing the location, etc. of the data
For information on the NetCDF data format, go to Unidata
- NetCDF.
The text files have an icon that looks like a sheet of
paper to their left and contain 2 header lines, the first is a short name for
each variable and the second is the units.
Text files are easily imported into Excel and will align
properly if you parse them using Space Delimited.

The current month will have the suffix *active.* to denote
that it is still being written.
The current month data files are updated hourly at 35
minutes after the hour.
