Sea ice kept oxygen from reaching deep ocean during last ice age, study finds（图）
Sea ice oxygen reaching deep ocean during ice age
2021/3/5
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...
New findings from the University of Michigan explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models predict.The study, published in Na...
In the words of Paul Simon, "these are the days of miracles and wonder."1 We live in a time when any given cruise can give rise to whole new concepts and observations that enhance understanding. Many ...
No laughing matter: Nitrous oxide rose at end of last ice age
No laughing matter Nitrous oxide end of last ice age
2014/12/30
CORVALLIS, Ore. – Nitrous oxide (N2O) is an important greenhouse gas that doesn’t receive as much notoriety as carbon dioxide or methane, but a new study confirms that atmospheric levels of N2O rose s...
CHAMPAIGN, Ill. — It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study from...
Study resolves discrepancy in Greenland temperatures during end of last ice age（图）
Greenland temperatures ice cores
2014/9/12
CORVALLIS, Ore. – A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming o...
There is growing scientific concern that corals could retreat from equatorial seas and oceans as the Earth continues to warm, a team of international marine researchers warned today.

The number of Americans who believe [sic] that our climate is changing has dropped 20 percentage points to 57% in the past two years. This figure should be a clarion call that we, as environmental sci...
The Age of Water and Ventilation Timescales in a Global Ocean Model
Ventilation Timescales Global Ocean Model North Atlantic Deep Water
2008/12/12
The age of water in the World Ocean is studied using a passive age tracer introduced into a global ocean model. Additional information is derived from a transient “dye” tracer that tracks the time-dep...
A Sea State Parameterization with Nonarbitrary Wave Age Applicable to Low and Moderate Wind Speeds
Sea State Parameterization Nonarbitrary Wave Age Applicable Moderate Wind Speeds
2008/7/31
A simple coupled flux and sea state model is developed. It is applicable to low, moderate, and high wind speeds, with a nonarbitrary wave age. It is fully consistent with an atmospheric flux parameter...
A general theory to describe and understand advective and diffusive ocean transport is reported. It allows any passive tracer field with an atmospheric source to be constructed by superposing sea surf...
The influence of stream age and environmental variables in structuring meiofaunal assemblages in recently deglaciated streams
The influence of stream age environmental variables structuring meiofaunal assemblages recently deglaciated streams
2014/5/4
The influence of stream age and environmental variables on meiofaunal assemblages were examined for 15 streams across a temporal gradient of 200 yr in Glacier Bay National Park, southeast Alaska. Meio...
Dissolved and particulate organic matter source-age characterization in the upper and lower Chesapeake Bay: A combined isotope and biochemical approach
Dissolved and particulate organic matter source-age characterization the upper and lower Chesapeake Bay A combined isotope and biochemical approach
2014/5/4
In order to characterize the sources and ages of organic matter contributing to river and estuarine outflow waters, the present study investigated Δ14C and δ13C signatures of the major operationally d...
Effects of short-term food variability on the plasticity of age and size at metamorphosis of porcelain crab larvae
short-term food variability age and size
2014/5/13
In a series of three experiments, we tested the effects of short-term food variability on the larval development
of Petrolisthes cabrilloi. We first reared seven sibling clutches of zoeae at 19...

Multispectral optical sensors Marine observation satellite ocean color optical oceanography
2015/7/29
A multispectral optical sensor collects data at select wavebands or channels. An example is the Sea-viewing Wide-Field-of-view Sensor (SeaWiFS) ocean color satellite, which measures eight wavebands be...
