Quantifying and understanding the processes driving turbulent mixing around Antarctica are key to closing Southern Ocean's heat budget, an essential component of global climate system. In 2016, a glider deployed in Ryder Bay, West Antarctic Peninsula, collected hydrographic microstructure data, obtaining some first direct measurements kinetic energy dissipation off Antarctica. Elevated O(10−8) ...

Sea ice is an important habitat for a wide variety of microalgal species. Depending on the species composition, sea can be seeding source pelagic phytoplankton blooms after melt in spring. Sea-ice algal communities were studied over 2 full winter seasons 2014 and 2016 at Rothera Research Station, situated Western Antarctic Peninsula (WAP). Algal pigment patterns microscopic observations combine...

In the science education research literature, it often appears to be assumed that students “possess” more or less stable “images of science” that directly correspond to their experiences with scientific practice in science curricula. From cultural-historical and sociocultural perspectives, this assumption is problematic because scientific practices are collective human activities and are theref...

--We studied the relation between nutrient reserves and reproductive performance of female Lesser Snow Geese (Chen caerulescens caerulescens) in 1971 and 1972 at the McConnell River (60ø50'N, 94ø25'W), Northwest Territories, Canada. We determined the potential clutch size of a pre-laying female by counting large (>20 mm), highly vascularized ovarian follicles; actual clutch size of post-laying ...

A protein of a biological sample is usually quantified by immunological techniques based on antibodies. Mass spectrometry offers alternative approaches that are not dependent on antibody affinity and avidity, protein isoforms, quaternary structures, or steric hindrance of antibody-antigen recognition in case of multiprotein complexes. One approach is the use of stable isotope-labeled internal s...

The effects of injection of BAL on the metabolism of lead has been studied by Eagle (1948) and by Ginsburg and Weatherall (1948) in animals poisoned with lead acetate, and by Ryder, Cholak, and Kehoe (1947) in human cases of acute lead poisoning. The action ofBAL has been shown to be the same both in experimental animals and in man; in animals it had no demonstrably protective action, and on oc...
