Abstract This study presents a high‐resolution reconstruction of the Antarctic Intermediate Water (AAIW) transport variability on the southeastern Brazilian continental margin over the last 16,000 years BP, based on grain‐size analysis. Variations of sortable silt (SS¯$$ \overline{SS} $$) are interpreted as changes in flow speed of the Intermediate ...

Detecting and attributing climate change effects on vegetation: Australia as a test case
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Successful valley bottom restoration requires an understanding of current and historical conditions determining whether a reach can currently support a multi‐thread or meandering channel, an understanding of reference conditions to assist with design, clear objectives to evaluate design alternatives, and post‐project monitoring of success using a ...

Diagenetic Effect on Planktic Foraminiferal Mg/Ca Records in the Arctic Ocean
Abstract Mg/Ca ratios in planktic foraminifera have long been used as a thermometer to reconstruct the past climate. However, this study revealed that in certain intervals, the Mg/Ca ratios of the planktic foraminifer Neogloboquadrina pachyderma, a widespread species in the Arctic Ocean, displayed anomalously high values which could severely bias paleo‐

Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)
