‘Rational use’ in Antarctic waters

Multidecadal warming of Antarctic waters.

Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss is largely driven by ice shelf basal melt, which is influenced by ocean-ice interactions and has been correlated with Antarctic Continental Shelf Bottom Water (ASBW) temperature. We document the spatial distribution of...

Iron in East Antarctic Snow: Implications for Atmospheric Iron Deposition and Algal Production in Antarctic Waters

To evaluate the deposition and solubility of aerosol iron in the Antarctic seasonal sea ice zone (SSIZ), iron was measured in snow samples collected from three areas in the SSIZ (Prydz Bay, Dumont d'Urville Sea and Ross Sea) and one continental area (Princess Elizabeth Land) of East Antarctica. Concentrations of total-dissolvable iron (that soluble at pH -2) ranged from 20-2950 pg g-l, with the...

Conservation and Management Frameworks for Sub-antarctic International Waters

The waters of rhe sub-Antarctic Southern Ocean are legally distinctive from those which fall within the Antarctic Treaty area extending to 60e S, not only because the Treaty does not apply in those waters but also because sovereignty over sub-Antarctic islands is largely uncontested. As a result, many of the countries claiming sub-Antarctic possessions are able to assert the full range of marit...

Improving Injectable Medicines Prescription in Outpatient Services: A Path Towards Rational Use of Medicines in Iran

Injection is one of the most common medical procedures in the health sector. Annually up to 16 billion injections are prescribed in low- and middle-income countries (LMICs), many of them are not necessary for the patients, increase the healthcare costs and may result in side effects. Currently over 40% of outpatient prescriptions in Iran contain at least one injectable medicine. To address the ...
