The last deglaciation of the Scandinavian Ice Sheet (SIS) from ∼21,000 to 13,000 yr ago is well-constrained by several hundred ¹⁰Be and ¹⁴C ages. The subsequent retreat history, however, is established primarily from minimum-limiting ¹⁴C ages and incomplete Baltic-Sea varve records, leaving a substantial fraction of final SIS retreat history...
This article presents the results of a high-resolution (1/12°), two-way nested simulation of the
oceanic circulation in the southwestern Atlantic region. A comparison between the model results and
extant observations indicates that the nested model has skill in reproducing the best-known aspects of the
regional circulation, e.g., the volume transport...
Observations show abrupt changes in the oceanic circulation of the southwestern Atlantic. These
studies report a southward drift of the Brazil/Malvinas Confluence (BMC) and a change in the spectral
characteristics of the Malvinas Current (MC) transport. We address the cause of these changes using the result
of a high-resolution numerical...
Background: Pearl millet [Pennisetum glaucum (L.) R. Br.] is a widely cultivated drought-and high-temperature tolerant C4 cereal grown under dryland, rainfed and irrigated conditions in drought-prone regions of the tropics and sub-tropics of Africa, South Asia and the Americas. It is considered an orphan crop with relatively few genomic and...
The Southeast Pacific, which encompasses the coasts of Peru and Chile, is one of the world's most productive regions resulting principally from the upwelling of subsurface nutrient-rich waters. Over the satellite altimetry era, there have been numerous evidence that surface mesoscale eddies play an important role in the offshore transport...
The Chloroflexi CL500-11 clade contributes a large proportion of the bacterial biomass in the oxygenated hypolimnia of deep lakes worldwide, including the world's largest freshwater system, the Laurentian Great Lakes. Traits that allow CL500-11 to thrive and its biogeochemical role in these environments are currently unknown. Here, we found that...
Chemical synthesis of oligonucleotides is a widely used tool in the field of biochemistry. Several methods for gene synthesis have been introduced in the growing area of genomics. In this paper, a novel method of constructing dsDNA is proposed. Short (28-mer) oligo fragments from a library were assembled through successive...
Located approximately 360 nm off the coast of Chile there is a disjoint realm of two small
oceanic islands systems, the Juan Fernández and the Desventuradas archipelago. Currently the local economy
of the islands is almost exclusively supported by the harvest and trade of marine resources, focusing mainly on
the...
Anomalous uplift is observed at the Lop Nor, China nuclear test site using ERS satellite SAR data. Using an InSAR time‐series analysis method, we show that an increase in absolute uplift with time is observed between 1997 and 1999. The signal is collocated with past underground nuclear tests. Due to...
