| On 10-12 June 2008, the NOAA Climate Observation Division sponsored the 2nd Joint Global Ocean Surface Underway Data (GOSUD)/Shipboard Automated Meteorological and Oceanographic System (SAMOS) Workshop in Seattle, WA, USA. The workshop focused on the ongoing collaboration between GOSUD and SAMOS and addressing the needs of the research and operational community for highquality underway oceanographic and meteorological observations from ships. The SAMOS initiative is working to improve access to calibrated, quality-controlled, surface marine meteorological data collected in-situ by automated instrumentation on research vessels (primarily) and select merchant ships. GOSUD is an IODE project which focuses on the collection, quality evaluation, and... |

| The ocean meteorological program of the Weather Bureau has two separate and distinct parts. First, there is the daily service by radio. Owing to the need for brevity, the radio reports contain a limited amount of essential information. The daily weather reports from ships and islands reveal the conditions over the ocean; when assembled on a map, including continental reports, they give a picture of weather conditions existing momentarily over a large region. A collection of observations is immediately returned to the mariner by radio broadcast so that he may draw his own weather map on shipboard. By this process, the weather at the earth's surface is mapped and much can be inferred as to conditions above the surface. Formation and movement of storms are... |

| The ocean meteorological program of the Weather Bureau calls in general for the making of but one regular observation a day, this, as well known, being made at noon· Greenwich mean time, (civil). However, in certain designated areas from which observations are transmitted by radiotelegraphy an additional regular observation is provided for at Greenwich midnight. Supplementing these regular observations are extra ones made under conditions of threatening or severe weather, gale and storm reports, and descriptive notes of weather experienced between observations, the lastnamed taking the form of a Daily Journal. The total requirements are such, however, as to make the smallest possible demands on observers consistent with the needs of the bureau in meeting... |

| Using the glucose and L-glutamic-acid to prepare the standard substance according to the ratio of 1:1, and the artificial seawater and the standard substance to prepare a series of standard solutions, the distribution pattern of uncertainty in measurement of seawater COD is obtained based on the measured results of the series of standard solutions by the potassium iodide-alkaline potassium permanganate determination method. The distribution pattern is as follows: Uncertainty in measurement is big and not constant at the high end, but small and constant at the low end. |

| The Conference of Brussels, called in 1853, was the first International Maritime Conference ever held. It sponsored the idea that governments should foster systematic weather observations on ships, and should prepare and publish charts of the prevailing winds, ocean currents, average sea and air temperatures, and tracks of dangerous storms based on the additional data. With the introduction of radio and fast ships, weather information became of vital importance to safe and efficient ship operation. Many countries began regularly scheduled weather forecasts to ships in nearby waters. Today, weather forecasts as well as charts are prepared from data collected through ship observations. Forecasts of weather and sea conditions arc prepared for ship operation,... |

| Newman's (1966) method of total root length estimation is modified and adapted to measure total length of filamentous algae in culture (i.c. <i>Polysiphonia</i>). This method makes possible a measurement and an estimation of the growth of the algae in culture without disturbing them. The petri dishes are placed on a 1x1 mm grid and the filament/grid intersections are counted. Total filament length (T) is given by T = Pi N (LxW)/4(LxW), with N = the number of intersections, L = the length and W = width of area in which the thallus is situated. Total filament length of <i>Polysiphonia</i> in culture estimated by the Newman method is compared with camera lucida measurements. The correlation between the results obtained by the 2... |

| A critical component of the Continuous Improvement and Innovation (CI&I) process described in Paper 4 above is Performance Assessment - analysing and interpreting the results achieved, and not achieved, in relation to the focus and target outcomes. This is made easier if specific Key Performance Indicators (KPIs) are established during Action Design and monitored during Action Implementation. The target outcome for the Measurement, Monitoring and Evaluation (MME) Strategy is to design and implement effective and efficient MME mechanisms that will demonstrate improvements and innovations in individual beef businesses and supply chains and in the broader Australian beef industry. |

| Biodiversity measurement is necessary to evaluate conservation alternatives and understand how to maximize biodiversity returns on conservation budgets. In the economics literature, most studies focus on species level diversity. Existing measures based on species' pairwise genetic differences do not perform optimally. This paper develops two new biodiversity measures within the same genetic framework. An axiomatic diagnosis for this class of measures is proposed and four biodiversity measures are then compared. Though the axiomatic comparison points towards a single "best" measure, it also indicates that the choice of measure should be dependent on the conservation problem at hand. |

| In Tanzania, as in many other developing countries, the conventional wisdom is that economic reforms may have stimulated economic growth, but that the benefits of this growth have been uneven, favoring urban households and farmers with good market access. This idea, although quite plausible, has rarely been tested empirically. In this paper, we develop a new approach to measuring trends in poverty and apply it to Tanzania in order to explore the distributional aspects of economic growth and the relationship between rural poverty and market access. We find that, between 1991 and 2003, a period of extensive economic reforms, the overall rate of poverty fell about 9 percentage points. The degree of poverty reduction was similar between rural and urban areas,... |

| Sustainable Value is a method to measure the contribution of an economic entity, such as a farm or the entire agricultural sector, towards the sustainability (sustainable development) of a region, a country or on a global scale. A positive sustainable value is created once resources are used more efficiently than by a benchmark. It shows the excess return that is created or lost by the use of economic, environmental and social resources by an economic entity relative to a benchmark. The purpose of this paper is to give an overview on the characteristics and requirements of the SV and to provide information on (a) possible applications and (b) extensions of the SV method related to the agricultural sector. A particular emphasis is put on the choice of... |
