We present a synchronization of the NGRIP, GRIP and GISP2 ice cores onto a master
chronology extending back to 104 ka before present, providing a consistent chronological …

Human activities have already modified the chemical composition of the natural atmosphere
even in very remote regions of the world. The study of chemical parameters stored in solid …

Two deep ice cores from central Greenland, drilled in the 1990s, have played a key role in
climate reconstructions of the Northern Hemisphere, but the oldest sections of the cores …

RECENT results1, 2 from the Greenland Ice-core Project (GRIP) Summit ice core suggest
that the climate in Greenland has been remarkably stable during the Holocene, but was …

DEFORESTATION and logging transform more forest in eastern and southern Amazonia
than in any other region of the world1–3. This forest alteration affects regional hydrology4 …

MANY tropical soils are poor in inorganic nutrients and rely on the recycling of nutrients from
soil organic matter to maintain fertility. In undisturbed rainforests such nutrients are recycled …

The evidence for the Little Ice Age, the most important fluctuation in global climate in
historical times, is most dramatically represented by the advance of mountain glaciers in the …

The Greenland Ice Sheet Project 2 glaciochemical series (sodium, potassium, ammonium,
calcium, magnesium, sulfate, nitrate, and chloride) provides a unique view of the chemistry …

The 3‐km‐long Greenland Ice Sheet Project 2 (GISP2) ice core presents a 100,000+‐year
detailed oxygen isotope profile covering almost a full glacial‐interglacial cycle …

It is suggested that the GRIP Greenland ice‐core should constitute the stratotype for the Last
Termination. Based on the oxygen isotope signal in that core, a new event stratigraphy …
