GESAMP - Reports and Studies, 97. The magnitude and impacts of anthropogenic atmospheric nitrogen inputs to the ocean
World Meteorological Organization (WMO) ; Food and Agriculture Organization (FAO); United Nations Educational, Scientific and Cultural Organization (UNESCO); et al. - WMO, 2018The present global modelling study of the Nr atmospheric cycle and Nr deposition to the ocean is the first that evaluates past, present and future Nr atmospheric deposition accounting for ON primary sources as well as for secondary ON chemical formation as a N-dependent process. While the total Nr deposition to the ocean is not expected to change significantly by 2050, the relative importance of oxidized and reduced N is expected to change, with an increasing proportion of ammonium compared to nitrate, resulting from more efficient controls on terrestrial emissions of nitrogen oxides (NOx) com ...

While the total Nr deposition to the ocean is not expected to change significantly by 2050, the relative importance of oxidized and reduced N is expected to change, with an increasing proportion of ammonium compared to nitrate, resulting from more efficient controls on terrestrial emissions of nitrogen oxides (NOx) compared to ammonia. This would result in a change in the acidity of the atmospheric deposition.

GAW Report, 203. The Atmospheric Input of Chemicals to the Ocean
World Meteorological Organization (WMO) ; International Maritime Organization (IMO); Food and Agriculture Organization (FAO); et al. - WMO, 2012The atmospheric input of chemicals to the ocean is closely related to a number of important global change issues. The increasing input of atmospheric anthropogenic nitrogen species to much of the ocean may cause a low level fertilization of the ocean that could result in an increase in marine 'new' productivity of up to ~3% and thus impact carbon drawdown from the atmosphere. However, the increase in nitrogen inputs are also likely to increase the formation of nitrous oxide in the ocean. The increased emission of this powerful greenhouse gas will partially offset the climate forcing impact res ...

Published by: WMO ; 2012The atmospheric input of chemicals to the ocean is closely related to a number of important global change issues. The increasing input of atmospheric anthropogenic nitrogen species to much of the ocean may cause a low level fertilization of the ocean that could result in an increase in marine 'new' productivity of up to ~3% and thus impact carbon drawdown from the atmosphere. However, the increase in nitrogen inputs are also likely to increase the formation of nitrous oxide in the ocean. The increased emission of this powerful greenhouse gas will partially offset the climate forcing impact resulting from the increase in carbon dioxide drawdown produced by N fertilization. Similarly, much of the oceanic iron, which is a limiting nutrient in many areas of the ocean, originates from the atmospheric input of minerals as a result of the long-range transport of mineral dust from continental regions. The increased supply of soluble phosphorus from atmospheric anthropogenic sources (through large-scale use in fertilizers) may also have a significant impact on surface-ocean biogeochemistry, but estimates are highly uncertain. While it is possible that the inputs of sulphur and nitrogen oxides from the atmosphere can add to the rates of ocean acidification occurring due to rising levels of carbon dioxide, there is too little information on these processes to assess the potential impact. These inputs may be particularly critical in heavily trafficked shipping lanes and in ocean regions proximate to highly industrialized land areas. Other atmospheric substances may also have an impact on the ocean, in particular lead, cadmium, and POPs. GESAMP initiated Working Group 38, The Atmospheric Input of Chemicals to the Ocean, to address these issues.

"The International Atomic Energy Agency (IAEA) has released its annual report for 2011. The report highlights, inter alia, its research activities on climate change issues in the oceans, isotope applications in hydrology and climate studies, and nuclear energy as a mitigation option.
The report indicates that the Agency strengthened its research activities to monitor radionuclides in the marine and terrestrial environment, and to study climate change issues in the oceans, in particular to study the impact of ocean acidification and climate change on oceanographic processes, ecosystems and associated services.
It stresses that the IAEA's Global Network of Isotopes in Precipitation, managed in collaboration with the World Meteorological Organization (WMO), has been the primary global database since 1961 for isotope applications in hydrology and climate studies. An atlas of isotopes in river waters was completed to aid the efforts of member States in monitoring the hydrological impacts of climate change, as rivers integrate the spatial and temporal changes in precipitation, water use and land use patterns in a catchment.
The report notes that increasing use of groundwater, in part to mitigate the impact of climate change, requires a better understanding of aquifer recharge, for which isotopes of noble gases are a powerful tool. In this context, IAEA informs that a portable sampling device for dissolved noble gases was developed in 2011 that allows wider use of isotopes for climate change adaptation studies."

Joint Radiation Emergency Management Plan of the International Organizations EPR-JPLAN (2010) : emergency Preparedness and Response
IAEA, 2010Pursuant to the obligations placed on it by the Conventions, the IAEA regularly convenes the Inter-Agency Committee on Response to Nuclear Accidents (IACRNA)2, whose purpose is to co-ordinate the arrangements of the relevant international intergovernmental organizations (‘international organizations’) for preparing for and responding to nuclear or radiological emergencies.

Pursuant to the obligations placed on it by the Conventions, the IAEA regularly convenes the Inter-Agency Committee on Response to Nuclear Accidents (IACRNA)2, whose purpose is to co-ordinate the arrangements of the relevant international intergovernmental organizations (‘international organizations’) for preparing for and responding to nuclear or radiological emergencies. Although the Conventions assign specific response functions and responsibilities to the IAEA and the Parties, various international organizations have — by virtue of their statutory functions or of related legal instruments — general functions and responsibilities that encompass aspects of reparedness and response. Moreover, some regional organizations (e.g. the European Union) are party to legally binding treaties and have directives and regulations that bear on emergency response arrangements among some States. There are also bilateral agreements between some international organizations that also have relevance to preparedness and response arrangements.

International Evaluation of Neutron Cross-Section Standards
IAEA, 2007Cross-section standards are required to be of high quality and accuracy to form the foundation of a wide range of important nuclear measurements and evaluations for both energy and non-energy applications. They constitute the yardstick for all other nuclear physics measurements. These standards have been re-assessed and evaluated to make significant improvements in the data, and to take into account important new experimental data and improved evaluation techniques. The methods employed were the most sophisticated ever used in cross-section evaluations. These present standards are more accurat ...

Database of Prompt Gamma Rays from Slow Neutron Capture for Elemental Analysis
IAEA, 2007Neutron-capture prompt-gamma activation analysis (PGAA) is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma ray emissions. Inaccurate and incomplete data have been a significant hindrance in the qualitative and quantitative analysis of complicated capture gamma spectra by means of PGAA. This database was produced to improve the quality and quantity of required data in order to make possible the reliable application of PGAA in fields such as materials science, geology, mining, archaeology, envir ...
