Note for Phase 5:
On February 23, 2011, JAMSTEC deployed the
fifth surface buoy JKEO5 at JKEO site (38-05.06' N, 146-26.87' E) during
the R/V Mirai MR11-02 cruise. The design of JKEO5 buoy is a little modified
from JKEO4 buoy with adding sensors of barometric pressure, precipitation,
and two acoustic current meters. MIO of JAMSTEC had set a CO2
measurement system on JKEO5 buoy. The meteorological data has been provided to institutions for
weather forecast and re-analysis numerical model calculation through GTS
since February 24, 2011 (WMO Buoy No. 21210). On August 16, 2012, the sensors for wind, relative humidity and
long-wave radiation were replaced by new ones. On June 23, 2012, JKEO5 buoy
system was recovered
The ASCII
formatted high resolution (10 min interval) meteorological data retrieved from the data
logger, and their daily and hourly means are
publicly available in this web page together with spot values of buoy
location fixed opportunistically by ARGOS and the noon positions derived
from them. The ASCII formatted high
resolution (10 min interval) and hourly oceanic data retrieved from the instruments equipped at recovered JKEO5 buoy
are publicly available in this web page together with daily means of hourly
data. It should be noticed that
the OceanSITES NetCDF formatted oceanic data are in
preparation.
1)
Since 00
UTC on February 26, 2011, the long wave radiation data were wrong.
2)
Since 07
UTC on March 7, 2011, the current meter data (U, V, T) at 125 m depth
indicated sometime zero value.
3)
Since 13
UTC on March 12, 2011, the current meter data (U, V, T) at 10 m depth
indicated sometime zero value.
4)
Since 00
UTC on March 13, 2011, the wind direction data were wrong,
5)
Since 22
UTC on May 7, 2011, the Relative Humidity data were wrong.
6)
On August
16, the sensors for wind, relative humidity and long-wave radiation were
replaced by new ones, and began again transmitting good quality data.
7)
Since
October 14, sea surface salinity data were wrong.
8)
Since
November 15, the wind data are being missed.
9)
Since
November 28, seasurface temperature and salinity are being missed.
10) Since
February 9, the wind sensor began again transmitting the data of which quality
is uncertain.
11) No data was
transmitted after March 19.
12) Buoy was
recovered on June 23, 2012, and no data was found to be stored in the data
logger after March 19.
