Physical Oceanography of Frontal Zones in the Subarctic Seas
Physical Oceanography Frontal Zones Subarctic Seas
2015/7/27
Fronts and frontal zones form natural boundaries in the oceans. Their effects are sometimes dramatic when seen from deck level, such as the massive changes in marine life, bird life, and ocean color s...
Subarctic Cetaceans in the Southern Chukchi Sea: Evidence of Recovery or Response to a Changing Ecosystem
Production sea ice the bering strait tourism sea ice cover
2015/7/16
The southern Chukchi Sea is one of the most productive areas in the world ocean. Over the past decade, there have been dramatic changes in this region in sea ice cover and in Bering Strait inflow, and...
Seasonal dynamics of autotrophic and heterotrophic plankton metabolism and PCO2 in a subarctic Greenland fjord
Biological metabolic kinetics Greenland fjord
2014/10/16
We measured net planktonic community production (NCP), community respiration (CR), and gross primary
production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
Microbial dimethylsulfoniopropionate (DMSP) dynamics along a natural iron gradient in the northeast subarctic Pacific
Microbial dimethylsulfoniopropionate DMSP dynamics along a natural iron gradient northeast subarctic Pacific
2014/4/17
We characterized the effect of an inshore-offshore gradient in Fe in the northeast subarctic Pacific on the bacterioplankton and phytoplankton assemblages and on the microbial cycling of particulate a...
The role of net community production in air–sea carbon fluxes at the North Pacific subarctic–subtropical boundary region
air–sea carbon fluxes net community production
2014/4/17
The North Pacific subarctic–subtropical boundary region is an important sink for atmospheric CO2
, with high
annual influx relative to surrounding waters and large seasonal variability. The location...
Effects of climate on organic carbon and the ratio of planktonic to benthic primary producers in a subarctic lake during the past 45 years
organic carbon benthic primary producers
2014/4/17
The effects of climatic variables on lake-water total organic carbon (TOC) concentrations and benthic and
pelagic primary producers during the past 45 yr were assessed using the sediment records of t...
Oceanic Subarctic Fronts of the Central Pacific：Structure of and Response to Atmospheric Forcing
Central Pacific Oceanic Subarctic Fronts Atmospheric Forcing
2009/3/7
The oceanic fronts in the subarctic region of the central North Pacific are investigated and related to atmospheric forcing. The thermohaline structure indicates a near balance between horizontal temp...
Large-Scale Response of the Pacific Ocean Subarctic Front to Momentum Transfer：A Numerical Study
Large-Scale Response Momentum Transfer Pacific Ocean Subarctic Front
2009/2/8
A numerical four-layer hydrodynamical model is implemented to investigate the role the atmosphere exerts on the dynamics of the subarctic front. While the effect of the westerly winds causes a southwa...
The Subarctic and Northern Subtropical Fronts in the Eastern North Pacific Ocean in Spring
Subarctic Eastern North Pacific Ocean Northern Subtropical Fronts
2009/1/10
The subarctic and subtropical frontal zones of the eastern North Pacific Ocean were surveyed in June for five consecutive years starting in 1972. These surveys from the basis for a description of the ...
Deep Currents in the Central Subarctic Pacific Ocean
Central Subarctic Pacific Ocean bottom topography Deep Currents
2009/1/5
Sections of closely spaced CTD stations along Longs. 165°W, 175°W and 175°E, in combination with 14-month current records from the central longitude, define two deep, nearly zonal currants, with speed...
Testing a Coupled Ice-Mixed-Layer Model Under Subarctic Conditions
Coupled Ice-Mixed-Layer Model Subarctic Conditions
2009/1/5
A one-dimensional oceanic mixed-layer model has been coupled with a thermodynamic sea ice model in order to study the seasonal cycle of ice-ocean interaction in the subarctic ocean. The ice thickness ...
Tracing terrestrial organic matter by d34S and d13C signatures in a subarctic estuary
Tracing terrestrial organic matter d34S and d13C signatures a subarctic estuary
2014/4/21
A key issue to understanding the transformations of terrestrial organic carbon in the ocean is to disentangle the latter from marine-produced organic matter. We applied a multiple stable isotope appro...
