Annex 1 to the Protocol consists of six parts as follows: Table 1-A, titled "List of Seismological Stations Comprising the Primary Network"; Table 1-B, titled "List of Seismological Stations Comprising the Auxiliary Network"; Table 2-A, titled "List of Radionuclide Stations"; Table 2-B titled "List of Radionuclide Laboratories"; Table 3, titled "List of Hydroacoustic Stations"; and, Table 4, titled "List of Infrasound Stations."

The six lists that comprise Annex 1 are the lists of facilities of the International Monitoring System (IMS). Article IV, paragraph 16 of the Treaty requires that the IMS shall be comprised of facilities for seismological, radionuclide, hydroacoustic, and infrasound monitoring, certified laboratories, and respective means of communication. Annex 1 lists the actual facilities for monitoring and the certified laboratories (but not the means of communication). Paragraph 2 of the Protocol also indicates that the IMS shall consist of the facilities specified in Annex 1.

The seismological monitoring portion of the IMS is specified by paragraphs 6 through 8 of Part I of the Protocol. It includes a global network of primary and auxiliary monitoring stations. The primary stations are listed in Table 1-A of Annex 1. These stations are to provide uninterrupted data, directly or through a national data center, on-line to the International Data Centre (IDC). Table 1-A lists the 50 stations of the primary network alphabetically by the state responsible for the station, and includes information on the location, latitude, longitude, and type of station.

The auxiliary stations are listed in Table 1-B of Annex 1. These stations are to provide data at any time on request by the IDC. The data are also provided directly or through a national data Centre. Table 1-B lists the 120 stations of the auxiliary network alphabetically by the state responsible for the station, and includes information on the location, latitude, longitude, and type of station.

Note that station number 20 in Table 1-A and station number 39 in Table 1-B have no information associated with them. Their entries in the tables read, "to be determined." These stations were originally intended to be in India. After India requested that all IMS stations on its territory be removed from the IMS, the entries were left blank. At the November 19, 1996 signatories meeting to establish the Preparatory Commission, statements were made making it clear that entries for these stations concerning their location and type, whether they are in India or elsewhere, will be left to the Preparatory Commission, and do not require adoption pursuant to the procedures outlined for changes of an administrative or technical nature, detailed in Article VII, paragraph 8 of the Treaty. Stations number 26 and 38 in Table 1-A, slated for Niger and Saudi Arabia respectively, do not have longitudinal and latitudinal coordinates listed in the Table. As in the case of stations originally intended for India, the exact locations will be determined by the Preparatory Commission, and will not be subject to the provisions of Article VII, paragraph 8.

The radiological monitoring portion of the IMS is specified by paragraphs 9 through 11 of Part I of the Protocol. It includes a global network of radionuclide monitoring stations and certified laboratories. Paragraph 10 of Part I of the Protocol requires a network of 80 stations to measure radionuclides in the atmosphere. Forty of these stations will also be capable of monitoring for the presence of relevant noble gases. Table 2-A of Annex 1 lists the eighty radionuclide monitoring stations. Table 2-A is alphabetical by the state responsible for the station, and includes the location, latitude and longitude of each station. Forty of the stations listed in Table 2-A will be designated by the Preparatory Commission for the installation of noble gas monitoring capability, subject to the approval of the Conference of the States Parties. In addition, the Conference will consider and decide at its first session on a plan for implementing noble gas monitoring capability throughout the network.

Paragraph 11 of Part I of the Protocol provides that the network of radionuclide monitoring stations will be supported by laboratories that must be certified by the Technical Secretariat and will perform, on contract to the Organization and on a fee-for service basis, the analysis of samples from radionuclide monitoring stations. Table 2-B of Annex 1 lists radionuclide laboratories that may also be drawn upon, as required by the Technical Secretariat, to perform additional analysis of samples from radionuclide monitoring stations.

The hydroacoustic monitoring portion of the IMS is specified in paragraphs 12 and 13 of Part I of the Protocol. It includes the establishment and operation of a global network of hydroacoustic monitoring stations. Paragraph 13 of Part I of the Protocol states that this network shall consist of the stations specified in Table 3 of Annex 1. Table 3 of Annex 1 lists the required network, which consists of 11 stations -- six hydrophone and five T-phase stations. Table 3 lists the stations alphabetically by state and provides location, latitude, longitude and type (i.e., hydrophone or T-phase). These stations shall provide data to the IDC in accordance with procedures to be developed in the Preparatory Commission and approved by the Conference.

The infrasound monitoring portion of the IMS is specified in paragraphs 14 and 15 of Part I of the Protocol. It includes the establishment and operation of a global network of infrasound monitoring stations. Paragraph 15 of Part I of the Protocol states that this network shall consist of the stations specified in Table 4 of Annex 1, and shall comprise an overall network of 60 stations. Table 4 lists the 60 stations alphabetically by the state responsible for the station and provides location, latitude and longitude. (Again note the discussion above with regard to stations on this list that are "to be determined".)
