Cruise Objectives

1.

To conduct detailed side scan and bathymetric surveys using Sea Marc II to locate possible sampling sites thought favourable for massive sulphide deposition on the active spreading centers;

2.

To photograph massive sulphide accumulations to help select the most promising areas to sample;

3.

To core sediments along rift valleys to determine the degree of metal enrichment;

4.

To dredge rift valley floors and fault scarps in areas of possible massive sulphide accumulations; and

5.

To detect active hydrothermal plumes using methane (CH) and helium 3 (3He) contents in hydrocast water samples.

Investigative areas of interest include: geomorphology, sedimentology, igneous petrology, geochemistry, existence and distribution of hydrothermal sources.

Model Schedule

Suva, Fiji to Honiara, Solomon Islands; Calendar year 1985; 3 in-port days; 22 sea days.

Staffing:

Co-Chief scientists-UH/HIG and CCOP/SOPAC

3.

To core sediments along rift valleys to determine the degree of metal enrichment;

4.

To dredge rift valley floors and fault scarps in areas of possible massive sulphide accumulations; and

5.

To detect active hydrothermal plumes using methane (CH) and helium 3 (3He) contents in hydrocast water samples.

Investigative areas of interest include: geomorphology, seafloor structure, sedimentology, igneous petrology, thermal regimes.

AGREEMENT AMONG THE GOVERNMENTS OF THE UNITED STATES OF AMERICA, NEW ZEALAND AND AUSTRALIA CONCERNING THE CONTINUATION OF MARINE GEOSCIENTIFIC RESEARCH AND MINERAL RESOURCE STUDIES IN THE SOUTH PACIFIC REGION

The Governments of the United States of America, New Zealand and Australia,

Recalling the Agreement among our three Governments in cooperation with the Committee for the Coordination of Joint Prospecting for Mineral Resources in South Pacific Offshore Areas (CCOP/SOPAC) relating to the Conduct of a Joint Programme of Marine Geoscientific Research and Mineral Resource Studies in the South Pacific Region - Second Phase ("the Phase II Agreement"), done at Washington on 19 September 1984, which Agreement expired by its terms on 19 September 1987.

Noting that work under the Programme has in fact continued since the expiration of that Agreement, and Recognizing that CCOP/SOPAC has been recently reconstituted as the South Pacific Applied Geoscience Commission (SOPAC),

Have agreed as follows:

ARTICLE I

This Agreement shall be referred to as the "Tripartite Phase II Extended Agreement".

ARTICLE II

The Parties shall continue the Second Phase of the Joint Programme in accordance with the provisions of this Agreement. The scientific and technical programmes which may be conducted in implementation of this Agreement are set forth in the attached Annex. Amendments may be made to this Annex by mutual arrangement between the Joint Programme Coordinator and the national coordinators.

ARTICLE III

For the purposes of this Agreement the following provisions of the Phase II Agreement shall apply:

Article I;

Article II(a), (d), (e), and (f);

Article IV(a);

Article V(a);

Article X;

Article XII;

Article XIII(b), (c), (d), (e), and (f);

Article XIV; and

Annex A.

ARTICLE IV

All activities to be carried out under this Agreement are subject to the availability of funds.

ARTICLE V

This Agreement shall enter into force on the date of signature and shall remain in force for five years. A Party may withdraw from this Agreement at any time by giving six months notice in writing to the other Parties.

IN WITNESS WHEREOF, the undersigned, being duly authorized by their respective Governments, have signed this Agreement.

Done at Washington, in triplicate, this tenth day of September, 1990.

ANNEX

The scientific and technical objectives of the Tripartite Phase II Extended Agreement are set forth below and will be implemented in association with SOPAC personnel:

OBJECTIVE A: PRESENTATION OF RESULTS

This objective is to present to SOPAC technical staff and pertinent country officials and their technical staffs briefing sessions/workshops reporting upon the results of Tripartite I and II cruises (supplemented by other data where appropriate). These briefings, made in-country, by Tripartite and SOPAC scientific experts, will be presented in non-technical terms and will be adequately illustrated to inform the audience of mineral and hydrocarbon potential, and geohazards, as presently known. During the workshop phase Tripartite scientists will assemble camera-ready information that can be used for an informational brochure. It is anticipated that the island countries will use this material for distribution to industry and other likely interested parties. Approximately three to four days will be spent in each briefing session/workshop.
