Important Information for Proposers

Any proposal submitted in response to this funding opportunity should be submitted in accordance with the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. The NSF PAPPG is regularly revised and it is the responsibility of the proposer to ensure that the proposal meets the requirements specified in this solicitation and the applicable version of the PAPPG. Submitting a proposal prior to a specified deadline does not negate this requirement.

Dear Colleague Letter

Seafloor Geodesy 2022


Invites proposals to deploy seafloor transponders from NSF’s instrument pool for research in the Cascadia and Alaskan subduction zones. Proposals that target volcanic processes, transform processes, plate motions or polar regions are especially encouraged.

Dear Colleagues:

NSF recognizes the unique contribution of offshore geodetic measurements and recently funded the construction of 48 seafloor geodetic transponders, their benchmarks, and 3 wave gliders. A community workshop and report https://www.seafloorgeodesy.org/post/future-directions-in-seafloor-geodesy-2021-community-workshop highlighted several recommendations for the application of seafloor geodetic techniques to constraining offshore geodetic measurements in different environments. A follow-on community workshop https://www.seafloorgeodesy.org/post/workshop-on-the-alaska-and-cascadia-seafloor-geodetic-community-experiment discussed the design of a community experiment to deploy a subset of this instrument pool in the Cascadia and Alaskan subduction zones.

The subduction community experiment will only use a subset of the instruments available which leaves enough instruments to address other science needs. Considering this, NSF invites proposals for field campaigns to deploy seafloor transponders from the existing instrument pool for 1-4 sites at tectonic settings consistent with priorities identified in the 2021 Community Workshop report. The geodetic instruments have a depth limit of 3000 m. A multi-year deployment is envisioned with requisite waveglider surveys. Of particular interest are proposals that target volcanic processes, transform processes, plate motions, or polar regions.

PROPOSAL PREPARATION AND SUBMISSION

Projects can be PI-driven or Community-driven. Proposers should contact program officers Gail Christeson gchriste@nsf.gov or Michael Jackson mejackso@nsf.gov early in the proposal development process for seafloor geodetic facility budget preparation guidance. Proposals should be submitted by February 15, 2023, for full consideration.

TO WHAT PROGRAM SHOULD I SUBMIT MY PROPOSAL?

While additional funds may be provided by other programs as appropriate, interested parties should plan to submit all proposals for deployment of these seafloor geodetic instruments to the Marine Geology and Geophysics (MG&G) Program.

PEER REVIEW AND FUNDING

Proposals will be reviewed with and compete for funding with other proposals submitted to the MG&G Program. As such, the total budget should be commensurate with the proposed scope of activities.

Sincerely,

Alexandra R. Isern
Assistant Director
Directorate for Geoscience
