  • Title: CLS - Argos : Newsletter 53 - Editorial - Argos on the Web
    Descriptive info: Argos Newsletter N° 53 - August 1998.. Editorial.. Welcome to this special issue of our Newsletter on Argos and the World Wide Web.. We have all watched the Web grow to become, in many places, a part of everyday life.. As recently as three years ago, millions of today's Web surfers had not even heard of the Internet.. Millions of participants are now attempting to sort out the functionality and value of this new technology.. In some cases, they are finding it where it was least expected-ironically one of the world's most popular Websites is used to sell of all things books! We too are continuing to evaluate the most effective ways to utilize this new medium.. One example of how we are using the Web involves a new Animal Tracking Forum.. The CLS and Service Argos sites are now linked to this forum dedicated to wildlife studies.. As well as containing articles on animal migration and physiology, the forum is a great place to exchange ideas and information related to wildlife tracking programs and the Argos system.. No matter how it progresses  ...   small sample of these efforts through articles about their sites.. Subjects range from El Niño and data buoys to tracking eagles and curlews.. You will also find articles about the sites operated by Service Argos, Inc.. and by a transmitter manufacturer.. Exciting times are ahead for the Argos system, thanks in part to the Internet.. Soon, you will be able to enter or modify your program requirements on line, instead of filling out paper forms.. You'll access your Argos results from our Websites, and enjoy a better choice of delivery options, for example platform tracks displayed on maps instead of as coordinates.. And, with Downlink Messaging on future satellites, you'll control your transmitters via the Web, for example to turn them on and off.. The Web will give you fast, flexible access to Argos data.. Our goal is to make the Argos System easily accessible and very flexible in addressing the requirements of our Users.. For this we continue to need feedback from our Users and ask that you feel free to provide your comments.. Jeff Wingenroth.. Vice President, Service Argos, Inc.. jw@argosinc.. com..

  • Title: CLS - Argos : Newsletter 53 - The Global Drifter Center at NOAA/AOML
    Descriptive info: Mark Bushnell.. Global Drifter Center.. E-mail:.. bushnell@aoml.. noaa.. gov.. http://www.. aoml.. gov/phod/dac/gdc.. html.. The Global Drifter Center.. at NOAA/AOML.. The Global Drifter Center at NOAA's Atlantic Oceanographic and Meteorological Laboratory maintains an array of drifting buoys worldwide.. A strong international community of cooperating oceanographers and meteorologists supplement the u.. s.. contribution, and the present array contains over 600 buoys.. The drifters all provide Sea Surface Temperature (SST) and ocean current observations.. Some also have barometric pressure, salinity, Global Positioning System (GPS), ocean color and/or wind speed and wind direction sensors.. All the drifters have a drogue, centered at a depth of 15 meters, to eliminate wind effects on the drifters and make them better current followers.. Drifters typically transmit for about 1.. 5 years, although some have lasted 5 years.. All drifters transmit data via Argos receivers aboard NOAA's two operational Polar  ...   Data Assembly Center (DAC) at aoml, and more than 3,500 drifting buoys have been deployed.. The DAC/GDC maintains a web site at.. gov/phod/dac/.. Photos of drifters being deployed, and present drifter locations are available at this site.. Maps showing the average ocean currents and the variability of those currents can also be found.. To encourage drifter deployments, oceanographers have added barometers and wind sensors to the drifters.. While this has helped to increase the number of drifters in the ocean, it has also forced oceanographers to begin data processing in real time.. At present, the GDC web site continues to operate at oceanographic time scales, relying upon Argos and GTS to distribute the data to forecasters.. As resources become available from meteorological agencies, data products from atmospheric sensors will be displayed at our web site.. Figure 2: Status of global drifter array..

  • Title: CLS - Argos : Newsletter 53 - WOCE Works the Web
    Descriptive info: N.. Penny Holliday.. WOCE International Project Office.. penny.. holliday@soc.. soton.. ac.. uk.. soc.. uk/OTHERS/.. woceipo/ipo.. http://diu.. cms.. udel.. edu/woce/.. WOCE Works the Web.. The World Ocean Circulation Experiment (WOCE) is the part of the World Climate Research Programme that will provide improvements in ocean circulation models for use in climate prediction.. The oceans are a key element in the climate system in the way they transport heat and fresh water and exchange them with the atmosphere.. WOCE used resources from 25 countries to make in-situ and satellite observations of the global ocean between 1990 and 1997 and to observe poorly-understood but important physical processes.. In parallel, great advances have been made during WOCE in the ability of ocean models to reproduce the known characteristics of the ocean and its circulation.. Figure 1: The WOCE Hydrographic Survey Grid.. Dissemination of information and data is a priority for WOCE and until recently the main route for rapid distribution had been through paper  ...   be kept up-to-date and distributed in a huge variety of forms.. All WOCE Data Centres now have active Web sites and the majority provide access to data and products through their sites.. The ipo and the Data Information Unit provide details of all aspects of the programme ranging from field work summaries, to investigators' contact addresses, meeting and conference information and a bibliography of WOCE publications.. The caveat to this is that the Web is not truly global, and can be slow and difficult to access for many people.. WOCE remains committed to disseminating data and information on alternative media such as paper documents and cd-roms.. A set of cd-roms containing Version 1.. 0 of the WOCE Global Data was recently produced and distributed at the 1998 WOCE Conference Ocean Circulation and Climate held in Halifax, Canada in May 1998.. Please contact the WOCE ipo for details of how you may obtain a set of the cd-roms (.. woceipo@soc.. )..

  • Title: CLS - Argos : Newsletter 53 - The Tropical Atmosphere Ocean (TAO) Array World Wide Web Site
    Descriptive info: L.. J.. Mangum, D.. C.. McClurg,.. D.. Stratton, N.. N.. Soreide,.. M.. McPhaden.. TAO Project.. atlasrt@pmel.. pmel.. gov/toga-tao/.. The Tropical Atmosphere Ocean (TAO) Array World Wide Web Site.. The TAO array consists of nearly 70 moored buoys spanning the width of the equatorial Pacific Ocean (Figure 1), a distance over one third the circumference of the globe.. Moorings of the array measure oceanographic and surface meteorological variables critical for improved detection, understanding, and prediction of seasonal-to-interannual climate variations in the tropics, most notably those related to the El Niño-Southern Oscillation (ENSO) events.. Figure 1: TAO Array.. The development and implementation of a real-time ocean observing system in the tropical oceans was one objective of the recently completed 10 year (1985-1994) international Tropical Ocean Global Atmosphere (TOGA) program.. The need for an ocean observing system in the Pacific was dramatized in the early planning stages for TOGA by the occurrence of the very strong 1982-1983 ENSO warm event, which was neither predicted nor even detected until nearly at its peak.. The TAO array is now one of the cornerstones of this observing system which also includes drifting buoy arrays, a volunteer observing ship expendable bathythermograph network, island and coastal tide gauges, an island wind profiler network, and remotely sensed measurements from both operational and research satellites.. The TAO project is a multi-national effort involving the participation of the United States, Japan, Korea, Taiwan, and France.. TAO measurements consist primarily of surface winds, sea surface temperature, upper ocean temperature and currents, air temperature, and relative humidity.. Data from most sensors are telemetered to shore in real-time via Service Argos.. A subset of these data are placed on the Global Telecommunications System (GTS) for distribution to operational centers for assimilation into weather and forecast models (Figure 2).. Figure 2: TAO system overview.. Data are received daily at NOAA's Pacific Marine Environmental Laboratory (PMEL) via Service Argos' Automated Distribution Service, where they are processed and quality controlled.. From the early stages of TAO development, it was recognized that data from the array needed to be accessible in near real-time to the entire oceanographic and meteorological community.. The first TAO web pages, real-time data displays, and ASCII data file  ...   of 1997 (Figure 3), and has reached a magnitude larger than that of any previous warm event in the past 100 years, including the 1982-83 El Niño.. Data from the array have provided for a day-by-day description in real-time of changing climatic conditions across the entire equatorial Pacific basin.. Also, the most accurate predictions of the current warm event were made using coupled ocean-atmosphere models that incorporated TAO wind, sst and subsurface temperature data into their initialization schemes.. Figure 3: Five-day mean zonal wind, STT and 20 C isotherm depth, 2 S to 2 N average.. A number of challenges were faced in setting up the TAO web pages.. Due to the real-time nature of the data, all of the TAO data files and graphics which are dependent on them must be updated daily.. Despite increasingly powerful central processors, several hours of computer time each day are required for reformatting, gridding, graphics display, and copying updates to the Web server.. Standard HTML (V3.. 2) is employed in the TAO pages to guarantee access to users from any of the widely available Web browsers.. CGI scripts have been written to create the gif images, and to return the gifs and any data requested to the user's web browser.. Due to bandwidth limitations, a cache system has been implemented for gif files on the PMEL server.. After a particular gif is generated from the data in response to the first user request on a given day, users making subsequent requests on the same day will receive the cached gif, saving cpu time on the server, and reducing response times for the user.. In the future, the TAO data set is expected to continue to grow in size and complexity with the integration of new sensors into the data stream, necessitating software and hardware enhancements on the TAO server.. The implementation of Java Applets will enhance the degree of interactivity with users and will give them more control of the displays and data processing.. Future efforts will concentrate on ensuring that high quality data, displays, and information are available to all interested users.. This article appears courtesy of.. Dr.. Michael J.. McPhaden,.. TAO Project Office director, NOAA/PMEL..

  • Title: CLS - Argos : Newsletter 53 - Polar Science Center International Arctic Buoy Program (IABP)
    Descriptive info: Ignatius G.. Rigor.. Polar Science Center.. igr@apl.. washington.. edur.. http://IABP.. apl.. edu/.. Polar Science Center International Arctic Buoy Program (IABP).. The Polar Science Center (PSC) of the Applied Physics Laboratory, University of Washington, in collaboration with the participants of the International Arctic Buoy Program (IABP), has maintained a network of drifting buoys on the sea ice of the Arctic Basin since 1979.. These buoys measure pressure, temperature, position, and a host of other meteorological quantities which are transmitted and collected via Argos.. These data are used for meteorological, climatological, and oceanographic purposes and serve both research and operational needs.. Traditionally, these data are archived at the World Data Center for Glaciology at the National Snow and Ice Data Center (NSIDC).. Researchers who wished to use the data were required to contact nsidc which would send the user magnetic tapes of the desired data by mail.. Needless to say, access to the data would take at least a few days.. To expedite the process, an FTP (File Transfer Protocol) server was installed in 1987.. This service provided users immediate access to the data via the Internet.. In 1994, an HTTP (HyperText Transfer  ...   Typical users of the data are scientists from various research institutions, who use the data to study topics ranging from pollutant transport by sea ice to global climate change.. Operationally, the data are used for forecasting the weather and ice conditions.. Officially, we have over 200 users internationally.. Access logs from the Web server, however, show that the Web server is currently accessed by over 500 different users each month.. Future enhancements are planned to take advantage of the many improvements in Web browsers.. Each year, for example, data reports for the buoys are published and mailed.. Digital versions of these reports can easily be made available on the Web.. The Web (ftp/http) address of the International Arctic Buoy Program is.. Acknowledgements: The International Arctic Buoy Program at the Polar Science Center is funded by the National Ice Center, which represents several U..

  • Title: CLS - Argos : Newsletter 53 - The Migration Route Satellite-tracked by ArgoSat NTT
    Descriptive info: Akio Kunii.. NTT World Bird Count Office.. wbc@wnn.. or.. jp.. wnn.. jp/wnn-n/w-bird/.. The Migration Route Satellite-tracked by ArgoSat NTT.. Figure 1: 15-gram Argos transmitter, used for tracking Far Eastern Curlews.. Argosat micro-miniature transmitters, developed by NTT, were attached to Far Eastern Curlews in Australia in March 1997.. Our hope was that the 15-gram transmitter, the world's smallest, would shed light on the migratory routes of this declining species.. NTT has supported wild bird tracking projects for over 10 years by developing and repeatedly miniaturizing tiny transmitters to mount on birds.. On the request of BirdLife International, an umbrella organization for the world's protection agencies, we took up the new challenge of further miniaturizing the transmitter: from 25 grams to 15 grams.. A readily-available 15 gram transmitter is a breakthrough for wild bird conservation: only with such lightweight devices is it possible to survey the migratory routes of medium-sized or small birds like Waders and Sand-pipers.. After studying the three main  ...   weighing less than 15 grams.. With the Argosat transmitter mounted, some Eastern Curlews stayed in their wintering grounds in Australia, while others flew to their breeding grounds.. NTT displays easy-to-follow bird tracks at one of its wnn (World Nature Network) websites, called The Migration Route Satellite-tracked by Argosat (http://www.. jp/wnn-n/migrant/english/index.. html).. By July 1997 there had been 100,000 page hits from bird experts, students and other Internet users from around the world.. We also expect the page to help raise public interest in nature and wildlife conservation.. NTT is continuously using the Argosat transmitter to help plot the migratory routes of other birds.. Species tracked will include the critically endangered Black-faced Spoonbill, from spring 1998.. The tracks will be presented on the website as the data arrives; so too will the continuing voyages of Far Eastern Curlews.. Figure 2: The Wild Bird Society of Japan and Yamashina Ornithological Research Institute are also tracking Black-faced Spoonbills.. Dotted lines show predicted migration paths..

  • Title: CLS - Argos : Newsletter 53 - Satellite Tracking of Threatened Species
    Descriptive info: Margaret Williams.. (NASA).. williams@sauquoit.. gsfc.. nasa.. Allen Lunsford.. (GST),.. David Ellis.. (Patuxent),.. Jon Robinson.. (Hughes STX).. Patrick Coronado.. (NASA),.. William Campbell.. http://sdcd.. gov/ISTO/satellite_tracking.. Satellite Tracking of Threatened Species.. Can you watch the birds fly, right on your computer monitor? Yes, you can! All you need is browser software, and an internet connection.. Point your browser to our web site and see what the scientists see to study the flight patterns and migration routes of threatened/endangered birds.. The project we are referring to is the result of a joint effort of two U.. federal agencies, NASA Goddard Space Flight Center (GSFC) and the Patuxent Wildlife Research Center.. We initially joined forces in 1990 in a project that used satellite telemetry to discover the winter home of a tiny dwindling population of Siberian Cranes.. Since then several projects have emerged, and a web site was created to follow some of these activities.. This web site is called the Satellite Tracking of Threatened Species and its location is.. It describes the overall program, and links you to three subsections that describe the projects in more detail.. Satellite Direct Readout.. This site gives you an overview of how the program works, the agencies involved, and how the bird is actually tracked by satellite.. You'll get a sense of the entire spectrum of the program with Patuxent scientists at one end (studying the birds' habitats, and strapping tiny transmitters [PTTs] onto the birds), and NASA at the other end (processing and correlating the data into bird locations).. But right in the center of all this is a company called CLS/Service Argos.. This company plays a key role in the feasibility of the program, for it enables access to the satellite data from transmitters around the world..  ...   full of things to see and read about.. It features a slideshow of the birds involved in the project and their natural habitats.. You can read the actual trip reports and published articles describing these and other unique studies being developed to protect these birds.. Visit this site to learn how and why scientists are training cranes to follow a truck and geese to follow ultralight aircraft.. A Guestbook is available for our web site visitors to send us electronic mail.. Some of the birds we feature and will be featuring at this web site are:.. 1) harpy eagles in Panama and Venezuela,.. 2) some African eagles,.. 3) cranes in Siberia and Canada,.. 4) steppe and golden eagles in Mongolia,.. 5) cranes that have been lead on migration by a truck or by ultralight aircraft,.. 6) fish eagles in Madagascar.. Our web site has been on-line for about 2 years.. On average, we get about 7 unique IP hits per day.. We get hits from both elementary and college students, from federal agencies and commercial companies, interested individuals, and just plain web surfers who have dropped us an email from time to time just to tell us what a great program they think this is.. We plan to continue following the activities of the NASA-Patuxent projects and continue to feature the many articles that are published on these and other similar projects.. As web technology improves, we expect to stay on the leading edge to make our web site more interactive with our viewers and to bring them closer to the environmental dilemma of these beautiful yet vulnerable birds.. We all share the hope that these birds will continue to fly the skies of the most beautiful planet in the universe..

    Descriptive info: Etienne Charpentier.. Technical Coordinator, DBCP.. charpentier@cls.. cnes.. dbcp.. gov/dbcp.. Data Buoy Cooperation Panel.. The Data Buoy Cooperation Panel (DBCP) is an international body which coordinates drifting and moored buoy programs worldwide.. Its main purpose is to increase the number of buoys deployed and the amount of good-quality oceanic and atmospheric data available for the international community.. Most of the buoys report through the Argos system.. Figure 1: Data Buoy Cooperation Panel Action Groups.. The DBCP is an official joint body of the World Meteorological Organization (WMO) and the Intergovernmental Oceanographic Commission (IOC).. It was formally established in 1985, and will be integrated in the Global Ocean Observing System (GOOS).. The current DBCP chairman is Graeme Brough, in charge of instrument engineering at the Australian Bureau of Meteorology (BOM) in Melbourne.. DBCP achievements include:.. Implementation of a dedicated sub-system at the U.. and French Argos centers for data processing and insertion of Argos data onto the Global Telecommunication System (GTS).. Implementation of Quality Control Guidelines for GTS buoy data.. Participation, with the Surface Velocity Programme, in the design of a new low-cost meteorological/oceanographic barometer Lagrangian drifter..  ...   (IABP).. International Programme for Antarctic Buoys (IPAB).. International South Atlantic Buoy Programme (ISABP).. International Buoy Programme for the Indian Ocean (IBPIO).. Global Drifter Programme (GDP).. [The Tropical Atmosphere Ocean (TAO) array Implementation Panel (TIP) is due to join the DBCP as an action group in 1998.. ].. Regularly updated information and data products.. A lot of data on the site is regularly updated, such as archived quality control messages and the status of buoys transmitting data onto the GTS.. Some is in graphical form, e.. g.. trend in number of wind speed observations over time.. Similarly, in the section on GTS distribution, you can consult data products from the Drifting Buoy Data Assembly Center (DAC, Miami, USA) such as global Lagrangian drifter population maps, or annual mean velocity estimates by region or period.. The DBCP website also gives access to data from the Canadian Marine Environmental Data Service (MEDS) and Météo-France, by FTP, using interactive forms.. We now expect to add interactive access to U.. National Weather Service (NWS) data.. Our thanks to NOAA's Atlantic Oceanographic and Meteorological Laboratories (AOML, USA) for hosting the DBCP website..
