Water temperature, salinity, velocity, including ADCP ice tracking, collected from Bering Strait Moorings A2, A3, A4 in Bering Strait from 2019-09-07 to 2021-07-09 (NCEI Accession 0253624)

This
is
an
archive
of
data
from
moorings
deployed
in
Bering
Strait
from
summer
2019
and
summer
2020
to
summer
2021.
Mooring
deployments
were
funded
by
the
NSF-Arctic
Observing
Network
award
PLR-1758565
(PIs:
Woodgate
and
Peralta-Ferriz).
The
mooring
work
required
3
dedicated
cruises:
-
in
2019
(5th
-
15th
September),
a
~
11
day
cruise
on
the
US
vessel
Norseman2
deployed
the
2019
moorings.
Some
CTD
sections
were
run
on
this
cruise,
and
those
data
are
archived
separately.
-
in
2020
(1st
-
18th
September),
a
~
19
day
cruise
on
the
US
vessel
Norseman2
deployed
the
2020
moorings.
Some
CTD
sections
were
run
on
this
cruise,
and
those
data
are
archived
separately.
-
in
2021
(7th
-
17th
July),
a
~
11
day
cruise
on
the
US
vessel
Norseman2
recovered
all
the
moorings.
Some
CTD
sections
were
run
on
this
cruise,
and
those
data
are
archived
separately.
In
both
2019
and
2020,
a
total
of
three
moorings
were
deployed
(each
year):
-
two
moorings
(A2
and
A4)
in
the
US
channel
of
the
strait,
-
one
mooring
(A3)
at
a
site
just
north
of
the
strait.
In
what
follows,
mooring
names
include
a
two
digit
suffix
to
represent
year
of
deployment.
Although
the
2019
moorings
would
normally
have
been
recovered
in
2020,
the
global
Covid
pandemic
prevented
this.
Instead,
the
2020
cruise
only
deployed
a
further
3
new
moorings
(each
~
400m
west
of
their
usual
positions).
All
6
moorings
were
recovered
in
2021.
Sites
A2,
and
A3
were
established
in
1990.
A2
and
A3
have
been
occupied
almost
continuously
(all
years
except
96-97)
since
then.
Site
A4
was
established
in
2001.
Mooring
location
A2
is
in
the
middle
of
the
eastern
(Alaskan
side)
channel.
Mooring
location
A3
is
just
north
of
the
strait,
immediately
east
of
the
Russian-US
EEZ
(Exclusive
Economic
Zone)
line.
Experience
has
shown
that
site
A3
samples
both
eastern
and
western
channel
water.
Mooring
location
A4
is
close
to
the
Alaskan
coast
and
allows
measurement
of
the
Alaskan
Coastal
Current.

of
instruments,
