Sea ice kept oxygen from reaching deep ocean during last ice age, study finds（图）
Sea ice oxygen reaching deep ocean during ice age
2021/2/25
Extensive sea ice covered the world's oceans during the last ice age, preventing oxygen from penetrating into deep ocean waters and complicating the relationship between oxygen and carbon, a new study...
Scientists at the Scripps Institution of Oceanography at the University of California, San Diego, have found that low oxygen levels in seawater could blind some marine invertebrates.The results, publi...
Transport and consumption of oxygen and methane in different habitats of the Ha˚kon Mosby Mud Volcano (HMMV)
Transport oxygen methane
2010/4/17
The Ha˚kon Mosby Mud Volcano is a highly active methane seep hosting different chemosynthetic
communities such as thiotrophic bacterial mats and siboglinid tubeworm assemblages. This study focus...
Episodes of low dissolved oxygen indicated by ostracodes and sediment geochemistry at Crystal Lake, Illinois, USA
low dissolved oxygen stracodes sediment geochemistry
2010/4/17
Low dissolved oxygen during the summer and early fall controls profundal continental ostracode distribution
in Crystal Lake (McHenry County), Illinois, favoring Cypria ophthalmica and Physocypria glo...
Mapping the spatial variability of plankton metabolism using nitrate and oxygen sensors on an autonomous underwater vehicle
Mapping the spatial metabolism using nitrate
2009/4/18
It is now possible to make highly resolved vertical (,1 m) and horizontal (3 m at constant depth and ,400 m
when undulating from surface to 100 m) measurements of nitrate concentration in the upper o...
Spatial and temporal variability of prairie lake hydrology as revealed using stable isotopes of hydrogen and oxygen
Spatial temporal variability hydrogen and oxygen
2009/4/17
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern
Great Plains, but little is known of how the relative importance of these processes may vary...
Spatial variations in time-integrated plankton metabolic rates in Sagami Bay using triple oxygen isotopes and O2 : Ar ratios
Spatial variations plankton metabolic rates
2008/4/21
Plankton metabolic rates, such as rates of gross, net community production and community respiration, were
measured in the surface waters using triple oxygen isotopes and O2
: Ar ratios. The 17
D a...
Long-term changes in the areal hypolimnetic oxygen deficit (AHOD) of Onondaga Lake: Evidence of sediment feedback
Long-term changes areal hypolimnetic oxygen
2006/4/30
Long-term trends in the rate of depletion of hypolimnetic dissolved oxygen (DO) are documented for ionically
enriched hypereutrophic Onondaga Lake, New York, for the 1978–2002 interval. Depletion rat...
Is phosphorus retention in autochthonous lake sediments controlled by oxygen or phosphorus?
autochthonous lake sediments phosphorus retention
2006/4/30
Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient
loading and installing aeration/oxygenation systems. For five eutrophic lakes, three...
The sensitivity of minimum oxygen concentrations in a fjord to changes in biotic and abiotic external forcing
minimum oxygen concentrations biotic abiotic external forcing
2006/4/30
We investigated the possible biotic and abiotic causes of the observed long-term decrease of oxygen minimum
concentrations in the deep water of Gullmar Fjord. Physical factors explained about 40% of ...
Coupled nitrogen and oxygen isotope fractionation of nitrate during assimilation by cultures of marine phytoplankton
Coupled nitrogen oxygen isotope fractionation

Meristematic oxygen variability in eelgrass (Zostera marina)
Meristematic oxygen variability eelgrass
2003/5/20
We examined the variability in oxygen content of meristematic tissues in eelgrass in order to evaluate its potential
role in events of sudden mass mortality within eelgrass beds. Oxygen content withi...
