BEST: The Impact of Changes in Sea Ice on the Physical Forcings of the Eastern Bering Ecosystem - Retrospective Investigation and Future Projection: High resolution modeling studies of present and future Bering Sea circulation
Chukchi
Borderlands: An Arctic Crossroads Collection of new field
data will be combined with historical data in order to model
the entrance into the Arctic Ocean, an area 600 miles north
of the Bering Strait. The objective of the work is to analyze
the role this crossroads area plays both in the Arctic and
in world climate.
Circulation
in the Freshwater Switchyard of the Arctic Ocean A program
to study freshwater circulation (sea ice + upper ocean) in
the “freshwater switchyard” between Alert (Ellesmere Island)
and the N. Pole.
Evolution
of Exopolymers Aquatic substances, Exopolymers substances
(EPS), are found in all marine ecosystems. An investigation
will study the potential of EPS to alter the bulk properties
of sea ice by means of biological alteration of the sea ice
texture. Also being studied are the environmental conditions
that lead to high concentrations of EPS in sea ice and how
the magnitude and variability of EPS affects the natural desalination
of sea ice during an annual ice cycle.
High
Latitude Dynamics This program strives to understand the
physics of the high-latitude oceans, including their circulation
illuminate the role of the polar oceans in climate, identify
the links between physical mechanisms and the biology and
chemistry of the high-latitude marine environment and achieve
a mechanistic understanding of the variability of cold oceans
and lakes.
International Arctic Buoy Programme maintains a network of drifting buoys in the Arctic Ocean to provide meteorological and oceanographic data for real-time operational requirements and research purposes including support to the World Climate Research Programme (WCRP) and the World Weather Watch (WWW) Programme.
Landfast
Ice. This program studies the long-term contribution of
landfast ice to the Arctic freshwater budget.
Collaborative Research: North Pole Station: A Distributed Long-Term Environmental Observatory, an international research team supported by the National Science Foundation (NSF) will establish a camp at the North Pole in April 2000 to lay the groundwork for a five-year project to take the pulse of the Arctic Ocean and learn how the world's northernmost sea helps regulate global climate.
The PathP:TOVS
Polar Pathfinder Project The Path-P data set provides
profiles of atmospheric temperature, humidity and cloud information
for the Arctic (North of 60 degrees) derived from the TOVS
satellite sounding system. It is a tool for the study of climate
processes in the Arctic. The data set is currently available
for the period 1979-1998.
Polar
Science Center Hydrographic Climatology (PHC). The goal
of this project is to produce a global hydrographic climatology
that includes a good description of the Arctic Ocean and its
environs.
Producing an Updated Synthesis of the Arctic's Marine Primary Production Regime and its Controls - The focus of this proposal is to synthesize existing studies and data relating to Arctic Ocean Primary Productivity (PP) and its changing physical controls such as light, nutrients, and stratification, and to use this synthesis to better understand how PP varies in time and space and as a function of climate change.
Projections of an Ice-Diminished Arctic Ocean, The goals of this project are 1) to understand the large-scale changes that have occurred in sea ice and the upper Arctic Ocean between 1948 and 2003, and 2) to project a diminished arctic sea-ice cover with multiple warming scenarios.
The Radarsat Geophysical Processor System (RGPS), currently
under development at the Jet Propulsion Laboratory with funding
from NASA, will use weekly synthetic aperture radar (SAR)
imagery of the entire Arctic Ocean, acquired by the Canadian
Radarsat satellite, to automatically produce gridded fields
of sea ice motion, thickness distribution of new ice, and
other data projects.
