Ocean satellite Imaging Systems (OSIS) was founded in 1998 by Jean Pierre Arabonis, in response for the need for economical satellite imagery for the fishing industry. Since then OSIS has undergone consistent growth to meet the demands of our clients, as well as branching into other sectors of the marine industry, namely shipping, salvage and ship routing. While remaining small we have built a solid reputation for speed, reliability and high quality. With our access to high speed computer networks and corresponding Oceanographers in Chile and Australia we are able to provide continuous coverage of the entire southern hemisphere.
We own and operate our own satellite reception ground station, hence can supply raw or processed NOAA satellite imagery for a variety of applications economically and speedily. As we retain a full backup system there is no chance of a disruption of service.
As our software can process several
different types of satellite data, we are able to process Landsat,
Radar, Modis, Spot, Seawifs imagery as well for special applications
Presently, besides the Noaa data, we are receiving data from the Chinese Fen Yung 1d satellite from which our ocean colour imagery is derived, presently this data feed is under development, and it is anticipated that the data will be operational by mid 2002.
We provide the full range of environmental services required for Towage and Salvage, including liaising with authorities on environmental matters, environmental and pollution reports, weather and sea state forecasting, chemical testing etc. Projects of this nature are handled with the highest priority from start to conclusion.
In support of the salvage consultation, oceanographic investigations are undertaken, this can be from pollution monitoring (e.g., Nitrates, phosphates, ammonia, oxygen, etc determinations and oil "fingerprinting") Projects can be undertaken either operationally, or in the form of recommendations forming part of an environmental impact assessment or engineering plan.
Further oceanographic services include the determination of circulation patterns and wave action within regions in support of larger engineering projects.
Marine Weather Forecasting
Weather forecasting is considered a support service to other activities, forecasts are generated from NOAA WaveWatch III model and NCEP mrf (medium range forecast) model, from experience the usage of these two models provide the most accurate forecasts for the Southern Hemisphere. The raw model data is downloaded daily ad processed according to empirical models run by us to tailor the final forecast to local conditions. Two main types of forecast are generated, a graphical output for large forecast areas and a text based forecast for fixed positions, all important variables are given, ie wind speed direction, swell height, direction, period, rainfall,humidity and barometric pressure. Our forecasts have been tried and tested operationally and have been proven to be among the best available under many different conditions.
