Appendix B to SeaWiFS Dear Colleague Letter

SeaWiFS Research Data Use terms and Conditions Agreement

NASA will furnish SeaWiFS data, either directly, or indirectly through a NASA-designated ground data processing and archive facility, to members of the SeaWiFS Science Team selected in response to a NASAResearch Announcement, to other researchers who may be selected by NASAon the basis of a SeaWiFS data use request submitted to NASA, and to

NASA contractors, as necessary.

SeaWiFS Data are defined as original data from the SeaStar satellite, the SeaWiFS instrument, or information derived from these sources which has been processed, reconstructed, enhanced, or reproduced by NASA and/or its support contractors, grantees, and/or research users.

NASA receives the right to use SeaWiFS data under contract with Orbital Sciences Corporation (OSC), with the express limitation that these data will not be used, reproduced, or disclosed for commercial or operational purposes without permission of OSC. The Individual SeaWiFS Data User__________________________[Herein referred to as User] is authorized to use, reproduce, and disclose SeaWiFS data and any information processed, reconstructed, derived, enhanced or, reproduced from such data solely for research purposes authorized by NASA.

As the overall consideration for the opportunity to use SeaWiFS data for research purposes, Individual SeaWiFS Data User agrees to the following terms and conditions:

1. If requested, the User will provide to NASA a copy of all products derived from SeaWiFS data and algorithms directly used to process the data.

2. The User will make available to the scientific community the results of SeaWiFS investigations through publication in appropriate journals or other established channels as soon as practicable and consistent with good scientific practice. Copies of reports or publications shall be furnished to NASA. If the reports or publications are copyrighted, NASA and OSC will have a royalty-free right under the copyright to reproduce, distribute, and use the copyrighted works for their purposes.

3. SeaWiFS data and any information processed, reconstructed, derived, enhanced, or reproduced from such data may be used, reproduced, and disclosed only for the purpose of NASA authorized research; and will not be used, reproduced, or disclosed for commercial or operational purposes, without the written permission of OSC. OSC is a third-party

beneficiary of this agreement. Accordingly, in the event of the breach or threatened breach of this agreement by the Individual SeaWiFS Data User, OSC is entitled to suspend or cancel the right to receive SeaWiFS data, and may exercise all other applicable legal remedies, including seeking injunctive relief.

4. Nothing in this agreement shall be construed as granting or implying any rights to, or interest in, patents or inventions of the Parties, or their contractors, subcontractors, or co-investigators (as appropriate).

5. This agreement covers all data in the User's possession that are less than five years old. Data become public domain five years after capture.

6. Commercial uses prohibited under this agreement involve the sale or resale of the SeaWiFS data and all SeaWiFS-derived data. Operational uses prohibited under this agreement involve the use of the SeaWiFS data and all SeaWiFS derived data during the two week period after the data are acquired, other than as specifically authorized by NASA.

Program Title

Episodic Events: Great Lakes Experiment (EEGLE). An experiment to assess the impact of episodic events on the nearshore-offshore transport and transformation of biogeochemically important materials in the Great Lakes.

Scientific Rationale

This project is part of a joint NSF/OCE and NOAA/COP program whose goals are 1) to determine what processes control the cross-margin (inshore to offshore) transport of biological, chemical, and geological materials in the coastal margins of the Great Lakes, and 2) to develop and test scientific strategies for assessing, quantifying, and predicting the impacts of multiple stressors, both natural and anthropogenic, in the Great Lakes or selected sub-regions. A tight coupling between contaminated sediments and overlying water exists in lakes and coastal ecosystems through the process of sediment resuspension. Satellite observations of suspended sedimentary material in Lake Michigan provide a unique opportunity to investigate an apparently annually recurrent episode of nearshore-offshore transport which can frequently consist of a 10 km wide plume of resuspended material extending over 200 km along the southern shores of the lake. The plume appears to be initiated by a major late winter storm after the melting of surface ice, and it eventually veers offshore along the eastern shore of the lake, coincident with the area of highest measured sediment accumulation in the lake. The inventory of particulate matter in the plume is comparable to the total annual load of fine sediments into the southern basin. Preliminary evidence indicates that this episodic event may be the major mechanism for cross-margin sediment transport in Lake Michigan. We believe this type of event is ideal for studying internal recycling of biogeochemically important materials (BIMS), ecosystem responses, and one of the major processes controlling cross-isobath transport in the Great Lakes. While we are focusing on a particular episodic process in southern Lake Michigan, the program results will be applicable to similar events in many coastal areas.

The purpose of this program is to create an integrated observational program and numerical modeling effort to identify, quantify, and develop prediction tools for the winter-spring resuspension event and to assess the impact of this event on the transport and transformation of BIMS and on lake ecology. Satellite remote sensing, including SeaWiFS, is expected to be a major source of data for interpreting in situ observations and for model development.

General Description of Spatial and Temporal Coverage

Spatial coverage will include the Great Lakes region. Temporal coverage will be from 1997-2003 (the expected duration of the EEGLE program).

NASA Archive

Processing Level II or III data may be requested from the NASA archive.

Publication Plans

SeaWiFS data may be used in Technical Reports and/or open literature publications (in accordance with the SeaWiFS Research Data Use Terms and Conditions Agreement).
