  • Faros Argentinos

    Según la definición del Diccionario del Bureau Hidrográfico Internacional, faro es "una estructura distintiva sobre una costa o alejada de la misma que presenta una luz principal destinada a servir de ayuda a la navegación". Más precisamente, una construcción costera que posee una señal luminosa característica cuya función es orientar al navegante. Generalmente ubicado en puntos destacados del litoral, en lugares altos, notables, ya sea artificiales o naturales. De su elevación dependerá el alcance que se quiera dar a la luz. En este sitio se actualizan las características nocturna y diurna de los faros permanentemente ya que afectan la Seguridad Náutica. No obstante, los navegantes deberán consultar las publicaciones reglamentarias Faros y Señales Marítimas, los Avisos a los Navegantes y Radioavisos Náuticos respecto a este tema.

  • Tablas de Predicción de la Corriente de Marea

    Se suministra las predicciones de corrientes en 27 puntos del litoral marítimo, la información brindada corresponde a los instantes predichos de ocurrencia de la estoa y de la máxima corriente. Para este último caso se da asimismo la intensidad de la corriente expresada en nudos (1 nudo = 1 milla náutica/hora) y la dirección en grados respecto al norte geográfico y con sentido de rotación hacia el este. Debe aclararse que la predicción incluye la corriente permanente, no así el efecto meteorológico sobre la corriente de marea. Es de notar que en algunas estaciones se predice la ocurrencia de dos máximos de corriente consecutivos. La causa estriba en que el mínimo de corriente ausente tiene un valor de intensidad que no puede considerarse como estoa.

  • Wave Model for the Southern Oceans and South Atlantic

    Hourly fields of 6 hours of retroanalysis and 96 hours of wave forecast, corresponding to the most recent forecast hour. The forecast hours are 00 Z, 06 Z, 12 Z and 18 Z and the products are estimated to be available at H + 4.5 hours. All heights are expressed in meters. The significant height is inferred in the model from the total energy of the waves. It resembles the characteristic height that an experienced observer visually estimates in a wave field and is the most widely used proxy measure of the field. However, it should be noted that individual waves can exceed significant height (ideally just over 13% of the waves) and even under normal conditions, an individual wave could double this height. The peak direction is the mean direction at the frequencies containing the maximum energy and is, in general, close to the direction of the maximum. The period of the energy peak or dominant period is the one corresponding to the frequencies that contain the maximum energy.

    • South Atlantic
    • Southern Oceans

  • Pronóstico Numérico de Olas (SMN)

    La altura significativa se infiere en el modelo a partir de la energía total de las olas. Se asemeja a la altura característica que un observador experimentado estima visualmente en un campo de olas y es la medida representativa del campo más utilizada. Sin embargo, se debe destacar que las olas individuales pueden exceder la altura significativa (idealmente algo más del 13 % de las olas) y aun en condiciones normales, alguna ola individual podría duplicar esta altura. La dirección del pico es la dirección media en las frecuencias que contienen la máxima energía y es cercana, en general, a la dirección del máximo. El período del pico de energía o período dominante es el correspondiente a las frecuencias que contienen la máxima energía. Todas las alturas se expresan en metros.

  • Accuracy and reliability of Paper Nautical Charts

    How accurate are nautical charts? How much faith can be placed in them? Unfortunately, the answer is quite complex – far more complex than simply saying one chart is accurate whilst another is not. However, having the necessary skills should be essential for any mariner venturing into unfamiliar waters. All charts, whether paper or electronic, contain data which varies in quality due to the age and accuracy of individual surveys. In general, remote areas away from shipping routes tend to be less well surveyed, and less frequently, while areas of high commercial traffic are re-surveyed frequently to very high levels of accuracy, particularly where under-keel clearances are small. It is quite accurate to consider a chart as a jigsaw of individual surveys pieced together to form a single image.

    The transit time of a celestial body refers to the instant that its center crosses an imaginary line in the sky - the observer's meridian. It's represents the time at which the body is highest in the sky on any given day: the transit of the Sun is local solar (sundial) noon. At the twilight time in the absence of moonlight, artificial lighting or adverse atmospheric conditions, the illumination is such that large objects may be seen but no detail is discernible. The brightest stars and planets can be seen and for navigation purposes at sea, the sea horizon is clearly defined (Geoscience Australia).

  • Depiction of charted information—electronic navigation chart vs paper chart

    This Pilot Advisory Note (2/2020) informs about circumstances where the information depicted on an ENC may differ to the information on a paper chart for the same location. Note that in all cases where a difference may be noted: 1) The ENC depiction will more closely resemble real-world features due to scale limitations inherent in paper charts; 2) ENC are used as the source for updating paper charts – updates to paper charts will therefore either be released in parallel with the ENC, or lag behind, but will never precede an ENC update.

    The Interactive Weather and Wave Forecast Map Viewer is used to display images of computer-generated forecast data for up to the next 7 days. The computer model generated maps contain no input from weather forecasters. The link of the map shows Day+0 data.

    • Sea (or wind) waves are generated by the local prevailing wind and vary in size according to the length of time a particular wind has been blowing, the fetch (distance the wind has blown over the sea) and the water depth.
    • Swell waves are the regular longer period waves generated by distant weather systems. There may be several sets of swell waves travelling in different directions, causing a confused sea state.
    • Combined sea and swell describes the combined height of the sea and the swell that mariners experience on open waters. The height of the Combined sea and swell refers to the average wave height of the highest one third of the waves. Combined sea and swell is also known as total wave height, or significant wave height. Some waves will be higher and some lower than the significant wave height. The probable maximum wave height can be up to twice the significant wave height.

  • The International Antarctic Weather Forecasting Handbook

    This volume presents a comprehensive account of the theory and practice of weather forecasting in the Antarctic. It is designed to be of practical use to forecasters on the Antarctic stations and on research/supply vessels, but will also be of value to those concerned with research into Antarctic meteorology and climatology. It splits broadly into two parts. In the first, the climatology of the Antarctic is reviewed and there are discussions on the nature of the weather systems found over the continent and Southern Ocean. The means used to forecast all the main meteorological elements are discussed as well as the use of satellite data and the output of numerical weather prediction models. In the second part, the meteorological conditions found at various locations around the Antarctic are considered and guidance provided on the forecasting rules and techniques used at specific locations (British Antarctic Survey).

  • Space Weather Services (SWS)

    • Space Weather Hazard

      Space Weather broadly describes the impact of solar activity on technological systems and human well-being here on earth. Dynamic variations on the surface of the sun can release large amounts of energy in various forms including electromagnetic radiation, charged particles and eruptions of huge clouds of ionised gas. These phenomena can significantly affect the earth’s upper atmosphere (ionosphere) and surrounding space environment with impacts felt all the way down to technological systems on the ground. Space weather events that modify the density and/or structure of the ionosphere can significantly impact the performance of HF communications, satellite communication and global navigation satellite systems (e.g. GPS).

    • Fact sheet on the potential impacts of space weather

      This information sheet is designed to assist owners and operators of critical infrastructure better understand the effects of space weather events. These may include disruptions to telecommunication and radio communications systems, satellite navigation systems, energy supply and power grids. Space weather could also lead to damage or loss of critical infrastructure.

    TEC Disturbance Index This index is defined as the mean deviation of the current conditions for the Total Electron Count (TEC) in the ionosphere from a 15-day running median reference data. An index of 1.5 mean there is a deviation of 150% between the current and the average TEC values. It is representative of the deviation of current ionospheric conditions from those expected by an usual GPS receiver. This deviation can cause a position error if it remain uncorrected. For the real GPS position errors refer to the L1 map below (More information about TEC mapping).

    S4 Index Ionospheric scintillation occurs when a radio frequency signal traverses a region of small scale irregularities in electron density in the ionosphere. This is a rapid fluctuation of radio-frequency signal amplitude. The S4 Index quantified this amplitude scintillation with a measure of the short timescale fluctuation in the signal to noise of a transmission. Values over 0.6 indicate strong scintillation which can cause loss of lock on a GPS signal. A scintillation index below 0.3 is unlikely to have any affect on GPS (More information about ionospheric scintillation).

    • GPS: L1 Ionosheric Positioning Error

      The ionosphere is a significant source of error in satellite navigation systems, such as GPS. In ordinary operation the position of a GPS receiver is estimated by measuring the time delay between a radio signal transmitted from each satellite and the reception of that signal at the receiver. Assuming a constant speed of light, this time delay can be converted to a receiver-satellite distance. By comparing the distance to multiple satellites a GPS receiver can determine its three dimensional position. The ionosphere disrupts this approach since the GPS radio signal is slowed by the presence of free electrons, causing an additional time delay and hence an error in the distance to each satellite. The greater the total number of electrons (Total Electron Count, or TEC) on the signal path, the greater the time delay.
      This near-real-time map shows the estimated GPS positioning error, in metres of L1, resulting from the difference between the GPS broadcast Klobuchar model of ionospheric delay and the best current estimate of 'true' ionosheric delay, as observed by SWS. It is therefore representative of the ionospheric contribution to GPS position error for single-frequency GPS, which at mid-latitudes typically ranges between 1 and 5m. Both enhancements and depressions of the ionosphere can result in reduced GPS positioning accuracy. The map shows colour contours of position error at GPS L1 (ie single frequency), in units of metres.

    Global space weather advisories for GNSS - MOD: Moderate, SEV: Severe

    • Space Weather Advisories

      Space weather can be described as the solar activity on the surface of the sun creating certain atmospheric events that can affect us here on earth. These environmental conditions are important for us to monitor as they can affect the performance and reliability of our satellites, navigation systems and radio communications. The space weather advisory service targets three broad space weather impact areas for ships: HF Communications (HF COM), GNSS-based navigation and surveillance (GNSS like GPS) and satellite communication (SATCOM). However advisories for SATCOM will not be issued by any space weather centres until further work is undertaken to develop and validate operationally relevant advisory thresholds for this impact area. Further information can be found in the companion Space Weather Hazard brochure. Advisories are issued at either of two intensity thresholds: Moderate (MOD) and Severe (SEV). More information.
