This site contains data from mooring sites in the Bering Strait region, deployed from 1990 to present day, under various funding sources. Not all moorings are deployed all years. Data are generally from ca. 10m above bottom, as discussed in the header to the data files. For science overview, see Bering Strait Home Page. For data overview, see archived readme files for 1990-2002 (both channels), 2002-2005 (US channel), 2005-2006 (US channel), 2004-2006 (Russian channel), 2006-2007 (both channels) For data, see links below. The 1990-2005 data are also
archived at JOSS/EOL
as part of the SBI program, and have also been submitted to NODC as Accession 0049437
The 2005-2006 data are archived at NODC as Accession 0013223. The 2004-2006 Russian channel data have been submitted to NODC as Accession 0045300. The 2006-2007 data have been submitted to NODC as Accession 0045300. Mooring positions A1, A2, A3 and A3' (black dots) are shown in the Figure to the left, superimposed on a MODIS sea-surface temperature for 26th August 2004 in the Bering Strait region. In the east, red indicates the warm Alaskan Coastal Current in the east. White areas indicate clouds.

 |
Salinity (top) and temperature
(bottom)
from ~ 9 m above bottom at site A3 and A3'.
Horizontal
axis is time starting in August with letters indicating
calendar
months. Black stars mark the 14-year monthly
climatology
of Table 1; thin black lines, the standard deviation;
and
the grey band, errors obtained from variance of the monthly
means.
Colored curves are 30-day running mean (with errors)
from
the various years (red= deployed in 1990
or
1991; magenta=1992, 1993; yellow=1994,
1995, green=1997, 1998, cyan=1999, 2000; blue=2001, 2002,
black=2003). A3' (deployed summer 1992 to summer 1995) data is
not included in the
climatology. Water column means are probably ~ 0.5 to 1 psu
fresher and 1 to
2°C warmer than these values
during summer/autumn. |

 Fourteen
year 30-day smoothed time-series of salinity (top)
and
temperature (bottom) from ~ 9 m above bottom at A1
(cyan),
A2 (blue), A3 (red) and A3' (green - summer
1992
to summer 1995). Line width indicates errors. Grey area
and
black lines are the climatology given above. Water
column
means are probably ~ 0.5 to 1 psu fresher and 1 to
2°C
warmer than these values during summer/autumn.
