The sedimentary record of Antarctic climate change
Read more of: The sedimentary record of Antarctic climate changeCircum-Antarctic marine sediments contain a record of past climate and Southern Ocean circulation that both complements and considerably extends the record in the continental ice. Variations in primary biological production, […]

The effect of sample emission on measurements of spectral parameters using a fourier transform absorption spectrometer
Read more of: The effect of sample emission on measurements of spectral parameters using a fourier transform absorption spectrometerRadiative transfer within an interferometric spectrometer is discussed in relation to measurements of infrared transmittance spectra of gases. It is shown that for certain types of interferometric spectrometers, radiation from […]

Feeding rates and diel vertical migration of copepods near South Georgia: a comparison of shelf and oceanic sites
Read more of: Feeding rates and diel vertical migration of copepods near South Georgia: a comparison of shelf and oceanic sitesSeventeen Longhurst Hardy Plankton Recorder profiles were taken over a diel cycle in January 1990 to study the feeding of four major copepods over the South Georgia shelf. Ontogenetic changes […]

Diel vertical migration and feeding of copepods at an oceanic site near South Georgia
Read more of: Diel vertical migration and feeding of copepods at an oceanic site near South GeorgiaTwelve Longhurst Hardy Plankton Recorder (LHPR) profiles were taken over a 16 h period in January 1990, in order to study feeding of four copepod species at an Antarctic oceanic […]

Aging live Antarctic fur seals and southern elephant seals
Read more of: Aging live Antarctic fur seals and southern elephant sealsThis study describes a method for extracting post-canine or incisor teeth from live antarctic fur seals (Arctocephalus gazella) and southern elephant seals (Mirounga leonina) respectively and their use to determine […]

A microbarograph for internal gravity wave studies in Antarctica
Read more of: A microbarograph for internal gravity wave studies in AntarcticaMeasurement of pressure fluctuations provides the best means of detecting atmospheric internal gravity waves at the Earth’s surface. We have developed an instrument which is sufficiently sensitive to detect the […]

Evidence of marine ice-cliff instability in Pine Island Bay from iceberg-keel plough marks
Read more of: Evidence of marine ice-cliff instability in Pine Island Bay from iceberg-keel plough marksMarine ice-cliff instability (MICI) processes could accelerate future retreat of the Antarctic Ice Sheet if ice shelves that buttress grounding lines more than 800 metres below sea level are lost1, […]

Biological and physical characterization of the seabed surrounding Ascension Island from 100–1000 m
Read more of: Biological and physical characterization of the seabed surrounding Ascension Island from 100–1000 mRecent studies have improved our understanding of nearshore marine ecosystems surrounding Ascension Island (central Atlantic Ocean), but little is known about Ascension’s benthic environment beyond its shallow coastal waters. Here, […]

High-resolution sub-ice-shelf seafloor records of twentieth century ungrounding and retreat of Pine Island Glacier, West Antarctica
Read more of: High-resolution sub-ice-shelf seafloor records of twentieth century ungrounding and retreat of Pine Island Glacier, West AntarcticaPine Island Glacier Ice Shelf (PIGIS) has been thinning rapidly over recent decades, resulting in a progressive drawdown of the inland ice and an upstream migration of the grounding line.
