Buoy status report
The following report on the status of GoMOOS buoys is compiled by Linda Mangum at the University of Maine.
U.Maine PhOG GoMOOS Status Report Update 18 October 2007
Budgetary shortfalls have forced the operations into austerity mode.
Under this mode of operation, problems with buoy performance are not
necessarily corrected at earliest opportunity because of ship charter
expenses. Instead we rely on local small vessels and good weather to
attempt repairs on nearshore buoys. Offshore buoys will be repaired if
ships of opportunity become available or if the buoy becomes a hazard
to navigation.
MOORING PROGRAM
Recent Updates:
Fall Turnaround: The first part of the fall turnaround was completed
during 17-24 Sep 2007. Buoys A01, B01, E01, F01, I01, L01, M01
and N01 were recovered and redeployed with new buoys and
instrumentation. All buoys are measuring surface met observations
every 10 minutes; surface wave and 1m temperature and salinity
are measured every 30 minutes. Currents and subsurface temperature
and salinity are reported hourly. Processed optics data from B01,
E01, F01, I01, and M01 are not available in real-time. Optics data
from A01 are avaiable in real-time.
Summary of Array Status:
A0119 Deployed 23 Sep 2007.
All data okay.
B0114 Deployed 23 Sep 2007.
All data okay.
C0214 Deployed 25 Mar 2007.
Visibility sensor replaced 7 Jul 2007. All data okay.
D0102 Deployed 1 Nov 2006.
Winds failed 28 Dec 2006.
35m salinity sensor failed on 20 Apr 2007.
Wind sensor replaced 31 Jan 2007 (mast/sensor damaged).
Winds failed again on 28 Jul 2007 (mast/sensor damaged).
Replaced wind sensor on 21 Aug 2007 but winds are still invalid.
Last data received from 20m optode 5 Sep 2007.
E0121 Deployed 18 Sep 2007.
All data okay.
F0116 Deployed 22 Sep 2007.
All data okay except for tower optics (PAR) sensor.
I0118 Deployed 18 Sep 2007.
All data okay.
J0214 Deployed 29 Nov 2006.
Wind sensors replaced 28 Feb 2007.
Last data received from 2m surface current meter on 28 Apr 2007.
Barometric pressure sensor flagged as invalid on 1 Jul 2007
(appears to have drifted high by 2 mb).
L0113 Deployed 21 Sep 2007.
Temperature and salinity data from 20m and 50m SBEIMs show
occasional corrupt data; otherwise all data okay.
M0112 Deployed 21 Sep 2007.
All data okay.
N0106 Deployed 19 Sep 2007.
All data okay.
Notes:
SBE37 sensors continue to be set to internally record temperature and
conductivity data every 3 minutes. We are only getting back hourly
data in realtime but the high resolution data from these sensors will
be available after the moorings are recovered and the data are
downloaded from the instruments.
All buoys (except D01) are deployed with dual wind sensors. The primary wind
sensors are Gill sonic anemometers and the backup wind sensors are
RM Young sensors.
Cruise Schedule: There will be one or more cruises sometime in late
October or early Novemeber to service buoys C02, D01, and J02.

CODAR PROGRAM
______________________________
Green's Island:
Current Status: Equipment being repaired.
Recent Visits:
A visit was made on 12 Sep 2007 to investigate damage caused by a storm
in Aug 2007. The transmitter and wireless internet antenna were found to
be damaged; the transmitter and receiver have been sent back to CODAROS
for repair. As soon as the repaired equipment are received, they will be
reinstalled on Green's Island.
______________________________
Cape St. Marys, NS Canada
Current Status: Operating normally.
Recent Visits:
A site visit will need to be made in the next few months to upgrate the
firmware so that the site can operate in multi-static mode.
____________________________
Wood Island:
Current Status: Operating normally.
Updates:
A site visit was made in July 2007 to reinforce and add concrete to the
antenna bases (they had been damaged in the storms earlier this spring).
_____________________________
Grand Manan:
With the cooperation and support offered by several units of the Canadian
Coast Guard, the installation of the site at the Canadian Coast Guard site
on Grand Manaan was completed between 6-10 August 2007. The assistance of
the unit of Towers and Antennas Systems was invaluable in doing the actual
installation. The Search and Rescue Unit contributed fencing material to
comply with the license requirement to erect a fence around the antennas
and the Towers and Antennas Systems Unit coordinated the actual installation
of the fence. The site was operational on 10 Aug 20067 but problems existed
in setting up communications to transfer the data from the site back to
U.Maine. A second visit was made on 17-18 Sep 2007 to install and set up the
wireless internet. Data are now being receieved at U.Maine and are presently
under evaluation to diagnose possible hardware issues. An antenna pattern
will need to be done at some later date.
______________________________
National Coordination:
Radial files from the GoMOOS Codar sites are now being transferred
to the Scripps/UCSD San Diego Coastal Ocean Observing System (SDCOOS)
prototype project. A server has been received and is being configured to
act as a northeast network portal.
