Paleoceanography is a peer-reviewed scientific journal published by the American Geophysical Union. It covers the history of the ocean and its plant and animal life. Paleoceanography accepts articles that reconstruct past conditions and processes recorded in sediments deposited in water. The main focus is on marine sediments, but also extends to sediments from freshwater environments. The past is reconstructed using sedimentology, geochemistry, paleontology, oceanography, geophysics, and modeling. Contributions are global and regional in scope and cover all ages, Precambrian to Quaternary, including modern analogs. Paleoceanography is abstracted and indexed by GEOBASE, GeoRef, Scopus, PubMed, Web of Science, and several CSA indexes. According to the Journal Citation Reports, the journal has a 2010 impact factor of 4.030, ranking it first out of 48 journals in the category "Paleontology", 8th among 165 journals in the category "Geosciences, Multidisciplinary", and 3rd out of 59 journals in the category "Oceanography".
In common parlance, the phrase "global climate change" is often used to describe how present-day climate is changing in response to human activities. But climate has also varied naturally and sometimes quite ...
Panama debate fueled by zircon dating: Americas connected earlier than thought
New evidence published in Science by Smithsonian geologists dates the closure of an ancient seaway at 13 to 15 million years ago and challenges accepted theories about the rise of the Isthmus of Panama and it ...
North Atlantic signalled Ice Age thaw 1,000 years before it happened, reveals new research
The Atlantic Ocean at mid-depths may have given out early warning signals – 1,000 years in advance - that the last Ice Age was going to end, scientists report today in the journal Paleoceanography.
Ocean primed for more El Nino
The ocean is warming steadily and setting up the conditions for stronger El Niño weather events, a new study has shown.
Microfossils reveal warm oceans had less oxygen, Syracuse geologists say
Researchers in Syracuse University's College of Arts and Sciences are pairing chemical analyses with micropaleontology—the study of tiny fossilized organisms—to better understand how global marine life ...
Past climate change and continental ice melt linked to varying CO2 levels
Scientists at the Universities of Southampton and Cardiff have discovered that a globally warm period in Earth's geological past featured highly variable levels of CO2.
The last ice age
A team of scientists has discovered that a giant 'burp' of carbon dioxide (CO2) from the North Pacific Ocean helped trigger the end of last ice age, around 17,000 years ago.
Modern ocean acidification is outpacing ancient upheaval, study suggests
Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
New high-resolution record of middle to late Miocene climate evolution
After the fairly warm Miocene climate optimum about 17-15 million years ago, Earth's climate began to cool. Holbourn et al. present a new high-resolution record of climate evolution over the middle to late Miocene from 12.9 ...
A selective approach to draw data from altered foraminifera shells
A sudden surge in the concentration of carbon dioxide in the air and the ocean 56 million years ago may have triggered the Paleocene-Eocene thermal maximum (PETM), a period of rapid and dramatic warming. In conjunction with ...
Shifts of the Subtropical Shelf Front controlled by atmospheric variations
In the western South Atlantic, off the coast of South America, a band of cold, fresh, nutrient-rich Sub-Antarctic Shelf Water (SASW) meets warm, salty, nutrient-poor Subtropical Shelf Water (STSW) to form the Subtropical ...
