Instructions to the Marine Meteorological Observers of the U. S. Weather Bureau, 1st edition. OceanDocs
Page, James.
The form of weather Report at present issued to vessels by the U. S. weather Bureau is a slight modification of that devised by the U. S. Signal Service for the purpose of its series of International Simultaneous Meteorological Observations, covering the period 1878- 1887, which form in its turn superseded the once well-known Meteorological Journal. The last-mentioned form of record, which went into effect in 1876, and which was in many respects identical with that recommended by the Maritime Conference held at Brussels in 1853, contemplated that the various meteorological observations should be entered at the end of every two hours throughout the twenty-four, or a total of twelve sets of observations per day. The new form demanded, in place of this...

Instructions to the Marine Meteorological Observers of the U. S. Weather Bureau, 4th edition. OceanDocs
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 G.M.T. (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 last- named 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 me ting its...

Instructions to the Marine Meteorological Observers of the U. S. Weather Bureau, 6th edition OceanDocs
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...

Manual of Marine Meteorological Observations, Eighth edition. OceanDocs
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 arc prepared from data collected through ship observations. Forecasts of weather and sea conditions arc prepared for ship operation,...

Mesure de la demande chimique en oxygène dans l'eau de mer. ArchiMer
Michel, Pierre.
Introduction: Measuring the chemical oxygen demand (COD) is a way of determining the organic matter in water based on its oxidisibility by bichromate. The presence of organic matter in sea water is one of the factors that determines the productivity of the oceans: whether this organic matter will be absorbed directly or must first be transformed into nutritive substances by bacteria. This beneficial action also has its limits. On the one hand, consumption of organic matter remains limited; when it exceeds a certain rate, there is no longer any increase in productivity. On the other hand, the excess organic matter deteriorates by consuming the dissolved oxygen and thus competes with marine life. In extreme cases, this excess can cause the eutrophication of...

Theorie et pratique de l'analyse de cohortes ArchiMer
Mesnil, Benoit.
Foreword: Sequential analysis of the demographic structures revealed by catches is currently the method most used, in particular by work groups working together within the framework of the C.I.E.M., to assess the characteristic parameters of exploited marine populations. The reasons for its success are due to a simple analytical definition, the absence of restrictive hypotheses, and especially a singular property thanks to which the results converge towards the parameters' true values. Due to its quasi-systematic use at the outset of the process leading to exploitation regulations, it is particularly important to take in the method's advantages, limits and rules of usage. This study is, in part, a review of the principal work performed on and around cohort...

Observation on the bacteriology of fronts : some problems of methodology ArchiMer
Floodgate, G.d.; Lochte, K.; Egan, B..
The data obtained in surveys to investigate the bacteriological aspects of the biology of two contrasting frontal systems has shown that the Inherent homeostasis and the complexity of the environment, together with the Imprecision of the data, lead to biomass values that are difficult to interpret in terms of the physical factors governing the formation of fronts. Although biochemical measurements offer some promise of providing more reliable and less confusing information, the oeed to develop high precision methods that can be made very frequently is emphasised.

An automated method for the assessment of mercury adsorption rates on particulate suspended matter OMA
Baeyens, W.F.J.; Decadt, G.; Dehairs, F.A.; Goeyens, L..
A continuous filtration system connected to a mercury auto-analyzer has been constructed for obtaining mercury adsorption rates on particulate suspended matter. The capabilities of this device have been demonstrated by carrying out a series of experiments under controlled physicochemical parameter conditions on samples of the Scheldt estuary. Duplicate measurements showed coefficients of variation ranging from 1 to 6 %. Depending on the physico-chemical conditions, the initial adsorption rate per unit of dissolved mercury concentration varied between 1.2 and 8.1 x 10<sup>-2</sup> mn<sup>-1</sup>.

Nutrition experimentale: Problemes methodologiques lies a l'utilisation des microorganismes comme source trophique ArchiMer
Guidi, L.
The present study deals with technical problems encountered under lab conditions in studies of trophic relations between deposit-feeding invertebrates and microorganisms. Using 2 pure cultures of Pseudomonas and Navicula , it was shown that these microorganisms will attach to artificial (glass beads) and natural (sand grains) substrates. Best microbial attachment was observed on sand (up to 4.8 x 10 super(8) cells.g super(-1) dry wt.). The radioactive labelling of the microorganisms depends not only on the form under which the isotope ( super(14)C) is supplied to the cultures, but also on the time and the duration of the labelling. 70% of the isotope was incorporated in a stable manner by the diatoms. The bacteria incorporated, at most, 34% of the...

The problems of application of radiocarbon method for estimation of primary production in oligotrophic waters ArchiMer
Krupatkina, D; Berland, B; Maestrini, S.
The errors in primary production estimation by the radiocarbon method may differ from one trophic region to another. Such supposition is based on unequal phytoplanktonic structural characteristics of these regions. These errors are likely to appear rather significant in oligotrophic waters predominated by nano- and ultranano-plankton (the so-called picoplankton). The organic substance of oligotrophic waters is obviously produced by picoplankton for the most part, the need for clarifying possible errors when estimating primary production by the radiocarbon method, which is the purpose of the present work is urgent. For these topics in oligotrophic waters, measurements were carried out in two ways: (1) according to the generally accepted pattern (Sorokin,...

Reduction du nitrate dans les sediments marins. Comparaison des activites mesurees in vitro et in situ ArchiMer
Esteves, J; Bonin, P; Blanc, F; Mille, G; Bertrand, J.
In vitro nitrate reduction in hydrocarbon-polluted marine sediments has been studied by flow-through system. By analysing the rate of nitrate comsumption as a function of nitrate concentration the authors determined the Michaelis-Menten kinetics parameters. (km = 330 mu M; vax = 2.0 mu M/g super(-1)/h super(-1). The authors found a value of 60 mu M/m super(-2)/h super(-1) for the rate of in vitro nitrate consumption derived from the above kinetic parameters and from the nitrate concentration in the sediment. In parallel a value of 67.4 mu M/m super(-2)/h super(-1) was found for the rate of nitrate consumption under in situ conditions. The great similarity between both results would favor the in vitro technique as a valid and more convenient one.

Distribución del mercurio total en los tejidos de un delfín nariz de botella (Tursiops gephyreus Lahille, 1908) de la provincia de Buenos Aires (Argentina) OceanDocs
Malaspina, A.M.; Pérez, A.; Moreno, V.J.; Bastida, R.O.; Aizpun, J.E..
Samples of seventeen different tissues of one specimen of the bottlenose dolphin Tursiops gephyreus, caught accidentally in waters adjacent to Mar del Plata by local fishermen (38°00'S; 57°20'W), were analyzed for total mercury distribution. The analytical procedure employed for total mercury involved a wet acid digestion followed by flameless atomic absorption. The method was based essentially on the one proposed by Armstrong and Uthe (1971).
