A first look at paleotemperature prospects from Mg in coccolith carbonate: Cleaning techniques and culture measurements

A culture-based calibration of benthic foraminiferal paleotemperature proxies: delta O-18 and Mg/Ca results

Benthic foraminifera were cultured for five months at four temperatures (4, 7, 14 and 21 C) to establish the temperature dependence of foraminiferal calcite δ18O and Mg/Ca. Two Bulimina species (B. aculeata and B. marginata) were most successful in terms of calcification, adding chambers at all four temperatures and reproducing at 7 and 14 C. Foraminiferal δ18O values displayed ontogenetic vari...

Internship: a closer look at its prospects.

orking in a hospital is quite different from sitting in a lecture hall listening to the professor. Having been charmed with the clinical aspects of medicine during ward postings in clinical years, interns enjoy the period of internship to the full extent. Should I be asked for my valued phase in the whole MBBS study – It would undoubtedly be internship for it offered me learning opportunity, be...

Demography in the Age of Genomics: a First Look at the Prospects

A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera

[1] Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record the equatorial Indian Ocean SST was 2.1 C colder during the last glacial maximum as compared to present times. The data further shows that the surface equatorial Indian Ocean was...

A first look at blazars with BeppoSAX

The ”blazar phenomenon” is due to the presence of relativistic flows (jets) emanating from the nuclei of active galaxies which are radio loud. The power to energize the radio lobes is transported in the jets. Blazars are the subset of radio loud AGN for which the relativistic jet happens to point at small angles to the line of sight. Since the radiation emitted by the jet is relativistically be...
