The warmest global climates of the past 65 million years occurred during the early Eocene epoch (about 55 to 48 million years ago), when the Equator-to-pole temperature gradients were much smaller than today (doi:10.1130/0091-7613(1995)023<1044:ECCALT>2.3.CO;2, doi:10.1038/nature08399) and atmospheric carbon dioxide levels were in excess of one thousand parts per million by volume (doi:10.1016/j.gca.2003.09.002, doi:10.1038/ngeo1186). Recently the early Eocene has received considerable interest because it may provide insight into the response of Earth's climate and biosphere to...

Palaeogeography, Palaeoclimatology, Palaeoecology, 337-338, 108-119

Judith Barke, Johan van der Burgh, Johanna H A van Konijnenburg-van Cittert, Margaret E Collinson, Martin A Pearce, Jonathan Bujak, Claus Heilmann-Clausen, Eveline N Speelman, Monique M L van Kempen, Gert-Jan Reichart, André F Lotter & Henk Brinkhuis
For a short time interval (c. 1.2 Myr) during the early middle Eocene (~49 Myr), the central Arctic Ocean was episodically densely covered by the freshwater fern Azolla, implying sustained freshening of surface waters. Coeval Azolla fossils in neighboring Nordic seas were thought to have been sourced from the Arctic. The recognition of a different Azolla species in the North Sea raised doubts about this hypothesis. Here we show that no less than five Azolla...

Late Cretaceous (Maastrichtian)-Quaternary summary biostratigraphies are presented for Ocean Drilling Program (ODP) Leg 189 Sites 1168 (West Tasmanian Margin), 1170 and 1171 (South Tasman Rise), and 1172 (East Tasman Plateau). The age models are calibrated to magnetostratigraphy and integrate both calcareous (planktonic foraminifers and nannofossils) and siliceous (diatoms and radiolarians) microfossil groups with organic walled microfossils (organic walled dinoflagellate cysts, or dinocysts). We also incorporate benthic oxygen isotope stratigraphies into the upper Quaternary parts of...

SAFARI 2000 Global Burned Area Map, 1-km, Southern Africa, 2000

The Global Burned Area 2000 initiative (GBA2000) was launched by the Global Vegetation Mapping Unit of the Joint Research Centre of the European Commission, in partnership with several other institutions, to develop reliable and quantitative information on the global magnitude and spatial distribution of biomass burning. The objective of GBA2000 was to produce a map of the areas burned globally for the year 2000, using the medium resolution satellite imagery provided by the SPOT-VEGETATION (VGT)...

E.A.G. SCHUUR
The objective of this study was to quantify net primary productivity as a function of rainfall in mesic to wet montane rainforests in Maui, Hawaii. The Maui Moisture Gradient is a sequence of 6 sites located on the island of Maui that range from 2200 mm to 5050 mm mean annual rainfall, while temperature and all other state factors (parent material, substrate age, organisms, and topography) that control NPP remain relatively constant. This data set...

SAFARI 2000 Meteorological Tower Measurements, Kruger National Park, 2000-2002

N.P. HANAN, R.J. SCHOLES & M. COUGHENOUR
An eddy covariance system mounted on a tower near the Skukuza Camp in Kruger National Park, South Africa, has been operating continuously since early 2000. Meteorological measurements started in February 2000, and the first flux measurements were made in April 2000. The site is unique in that the micrometeorological instruments are positioned on a tower located between two distinct savanna types, a broad-leafed Combretum savanna and a fine-leafed Acacia savanna. These contrasting savanna types are...
