Connections Among Atmospheric
Forcing, Runoff and Conditions in
the Laptev and East

Siberian Seas.

The First All

hands Meeting of CHAMP PIs and Co
-
PIs, 18

February 2003, Boulder, CO.

I.P.Semiletov and G.E.Weller

Since the great
Siberian rivers
play a significant
role in the
biogeochemical
regime of the
Arctic Ocean
through transport
of carbon and
nutrients into the
sea and through
permafrost
thawing, we
address

our
project to evaluate
the land hydrology
effect on the
environmental
change over
most
wide Arctic
shelf
: in the
Laptev and East
-
Siberian seas.

Goals of the atmosphere
-
land
-
shelf studies are follows:

1) identify what type of atmospheric circulation causes similarities or
differences in the precipitation regime of the main East Siberian and
their discharge using a complex analysis of types of atmospheric
circulation, meteorological and land hydrology records;

2) investigate the connection between the variability in discharge
(and their anomalies) in the main East Siberian Rivers and two
-
circulation regimes of the wind
-
driven Arctic Ocean as well with
dynamics of the Siberian High, and the difference between two
patterns of Arctic circulation in hydrology, hydrochemistry and
sedimentation (where available) in the Laptev and East
-
Siberian
Seas.

3) determine the linkage between multiyear variability (inter
-
annual
and intra
-
seasonal) of runoff and marine environment (hydrology
and hydrochemistry) and ice condition (where available)

Knowledge of the coastal processes as a linkage between land and ocean
processes in the Arctic is a primary interest of this project because the
major transport of fresh water, dissolved and solid material into the Arctic
Ocean is determined by 1) the fluvial discharges and 2) coastal erosion.

Modified from Semiletov, submitted to GRL

Major transport of terrestrial solid material into the Arctic
Ocean: the Laptev and East
-
Siberian seas.

We

determine

the

inter
-
annual

and

intra
-
seasonal

variability

of

atmospheric

forcing

over

East

Siberia

and

the

adjacent

part

of

the

Arctic

Ocean

that

influences

the

land

hydrology,

runoff,

water

circulation

and

biogeochemical

regime

on

the

East

Siberian

Shelf
.

How

we

do

this
:

by

acquiring,

synthesing,

integrating

and

comparing

land
-
shelf

(meteorology,

land

and

marine

hydrology,

hydrochemistry

and

sediment

data

for

two

seminal

areas

of

the

Arctic
:

1
)

the

Lena
-

Laptev

Sea

system,

and

2
)

the

East
-
Siberian

land
-
shelf

system,

which

is

influenced

strongly

by

the

Pacific

water

inflow
.

Data sets
.

All available meteorological,
hydrological, and hydrochemical
data sets obtained by the Russian
Academy of Sciences, Hydromet ,
Navy Hydrography, and other
institutions, and including results
of our own investigations (three
cruises along the Lena River from
Yakutsk to Tiksi, 1995, 1998,
1999; all
-
seasonal observations in
the Lena Delta, 1994
-
1996 and
seven summer
-
fall oceanographic
expeditions including Trans
-
Arctic Expedition
-
2000). Data are
taken from the published (USA
web sites), digitized and solid
Cadastre and Bulletin yearbooks of
Yakutian Hydromet (Yakutsk,
Tiksi, Cherskiy) and
Roskomhydromet (Moscow,
Obninsk), Russian Academy of
Sciences (Vladivostok, Moscow),
Far Eastern Hydromet, Navy
Hydrography as well from the
unpublished reports of Tiksi
Hydromet.
